Bodywork for CANAMSA
Fred W B - 18/4/06 at 02:30 PM

You guys may have noticed that I have not posted any progress updates on my project for a while. That is because, on top of some domestic projects getting in the way, significant progress has been made on a desk and in a computer, and not in the garage.

I posted previously (a long time ago) that I had purchased a 1:18 scale model of a Lola T70 Spyder, and that someone had undertook to measure it up for me on a 3 axis digital machine, "when he gets a chance". Problem is that he never did, so after over a year of waiting I went and got the model back.

In order to measure it myself, I made up a simple 3 axis measuring jig from alloy channel section and flat, steel rules, a straight edge and a digital vernier. Then with the aid of a colleague Andrew, I measured the offset of the body surface from the datum base at every point on a 5 mm x 5 mm grid, and recorded the measurements on a large piece of paper

Andrew then used this data and many reference photo's to draw the body surface in Inventor - One sentence that describes many hours of work.

Now we are using that data to produce drawings of many flat body sections (stations every 100 mm in the length) and some longitudinal stringers to position them, in DXF file format.

These will then be cut out on a CNC router from 8 mm plywood sheet, in order to start building the body plug. The router can handle 8' x 4' sheets.

I had promised myself that I would wait until I had pictures of the buck in construction before posting on my body progress, but I wanted something auspicious to be my 500th post.

Please see photo and screen shots below. The ribs screenshot I show is not yet complete.

Cheers

Huge respect to you Fred - the collation of all those measurements must have taken loads of time to do.
Judging from the ribs pic you have been very thorough too

Looks awesome - You have way more patience than me!

As a complete aside, Gardner Douglas are now selling a Lola T70 spyder kit in the UK.

When you have made your own moulds, are you planning to make a few more to sell?


C10CoryM - 18/4/06 at 10:18 PM

Looking good. Ive played with 3D programs so I know how much work that is. When I went to the monterey historics last year I met up with a guy from another forum who races a 1965 T70. (Yes I sat in it and made vroom vroom noises )
Anyhow, he may be willing to help you on some points. He is pretty busy though so may not be able to.
His website is here:

Fred W B - 19/4/06 at 11:04 AM

Hi guys, thanks for responses, and in particular C10CoryM for the very useful Link.

At this stage I am not planning to build more than one car, but you never know?

The link has helped explain something that has puzzled us, that being what should the rad exit duct (on top of the nose) and the body shape surronding the front brake air duct/driving light openings look like. Turns out there were mark 1 and mark 2 versions. The mark 1 has a small square rad exit duct- see scale model above, with "flat" round brake air duct/driving light openings - see light blue car, while mark 2 had a wider tapered rad duct, with brake air duct/driving light openings that seem to be more oval, and follow a smoother nose shape than the mark 1 - see mono picture . The GD replica 70 seems to use a mark 2 style rad duct, with mark 1 style driving light openings - see dark blue car.

Originally I had not intended to attemp an exact replica, to stop any pedantic's telling me I have this and that detail wrong but now that I am going to all this trouble, it seems a pity not to get it as right as I can.

So which one do I follow? I prefer the mark 1 rad exit duct, and the mark 2 brake air duct/driving light openings. I suppose I could do it that way, and call the car shape a tribute to a T70 spyder. Then again, presumably the nose was modified because of cooling problems. Currently our model is a mark 1.

How did people do this sort of thing before the internet??

Regards

Fred W B

sgraber - 25/4/06 at 07:29 PM

Hi Fred, Glad to see someone else taking up the task! Your work looks awesome!

I'm sure you have the process well in hand and therefore my suggestions may seem redundant. I'll post them for the benefit of others just casually looking in on your project.

If you recall I did the same cross-section thing with my 3D model (except it's my own original design) and then went to cad drawings which were taped to the wood sheets and cut with a jigsaw. I used 22 ribs along the length and interpolated the curvature. I don't know if you will need as many ribs as you have shown?

You will want to have as solid a substructure as possible. I have found my 2x4 structure woefully inadequate. And whatever you do, don't use styrofoam and drywall plaster! When you get out to the plug surfacing stage and are at a mirror finish, if your substructure is not rock solid, the mirror surface may appear to 'crawl' and move from day to day depending on humidity and temperature. So try to keep it in a temperature controlled environment. Specifically at these final stages.

Once again, Incredible progress you have made and I am now even more proud of you!

Fred W B - 4/5/06 at 11:19 AM

Hay Steve.

Thanks for the kind words. I have learnt a lot from following your progress.

I have had a conversation with the boss of one of my companies GRP suppliers, and he also reccommends gluing and screwing the buck framework together in order to make it as rigid as possible. As we cut the 8 mm plywood stations and ribs we will include matching groves so they will hopefully slot together jigsaw fashion. Below is half of the more or less complete set. It does look like a hell of a lot of wood, but I am hoping that going to all this trouble to produce a good framework with profiles that are exactly what I want will reduce the surfacing pain somewhat. We won't cut all the wood shown in the cockpit area.

Cheers

Just had the first trial station panel cut, to see if the CAD program talks to the CNC router okay. Came out pretty much perfect, just got to add a centre line reference. This is a transverse station on the front axle line, through the front wheel arches and rad duct.

Looks like I'm off to buy a pile of plywood.

Fred W B - 30/5/06 at 07:05 PM

90 square meters of 8 mm plywood loaded for delivery to the router guy.

The plywood is recycled from packing crates used to send stuff from GM Brazil to a GM plant here in Port Elizabeth.

Bloody hell that looks a bit complex! Good news on the progress front though, I was beginning to wonder if you'd had some major drawback or problem! How are you planning on doing the first layer of the moulds? Or are you filling all the gaps with something like polystyrene and then going over that?


Fred W B - 11/2/07 at 12:23 PM

Hi DIY

The hold up was this


WRT skinning the plug, I have had 350 polyurethane foam blocks cut, to glue into the "egg box" spaces to form the surface. These will be finished to shape and then the whole thing skinned with GRP and filler.

Cheers

Fred W B

[Edited on 11/2/07 by Fred W B]


DIY Si - 11/2/07 at 12:58 PM

Ah, I'd forgotten about that. Fair enough, I would gladly take time out to make such a nice garage/build space. Any guesses as to when the buck'll be ready? I imagine that'll be a fair sight all on it's own.


RazMan - 11/2/07 at 02:30 PM

I'm following your project with growing interest Fred.

When covering the 'egg box' with GRP are you going to anchor it to the surface with load spreader plates or similar? I was just thinking that it might need to be bonded in some way to avoid separation when it comes to removing the buck from the mould. Or is it going to be a sacrificial buck?


sgraber - 11/2/07 at 02:46 PM

Great progress Fred, and forgive me as I take the podium to say that you are doing the right thing by making sure you have a good base to start from. If I can give any advice to people seeing Fred's complex structure who are considering their own buck/plug/mold construct - Do not skimp on the understructure. I did, and paid for it over the years of struggle to prevent shifting and cracking.

Now, we could have a whole conversation about CNC milling the plug vs hand shaping.... But this is not the time or the place. Just LOOK at that amazing wood work! Lovely!


Fred W B - 12/2/07 at 02:56 PM

Hi Guys

Raz, I am hoping that the "skin" of GRP/filler will stay on the plug when I pull the moulds. I hadn't planned on doing anything more then just relying on the resin to stick the skin to the wood and foam base

Cheers

Most will melt away when the issue of getting paid to make one is raised.

Some things about folk are rather predictable unfortunately.

Looking very good (both of you) wish I had the time, space, money and talent* to make exactly what I want.

* Not necessarily in that order


Fred W B - 30/4/07 at 10:52 AM

Thanks Doug and iank

WRT the routing, the handling time was much more of a factor that the cutting time. The job was done in between real paying jobs, and took 3 or 4 weeks to complete, I think - It was a while ago!

Things I would do different next time would include putting 0.5 mm clearance in the interlocking slots (I made them dead 8 mm wide, to fit over the 8 mm ply and had to hammer the longitudinals in) and I would add some stations at the extreme rear, but fitted perpendicular to the body surface, not vertical. I would also make the longitudinal ribs thickness stick into the body shape from the actual longitudinal line, and not out as I have done. I still have to finish off all these edges flush with the eventual body surface.

Best thing I did was have lots of 92 mm wide planks cut, I've used them a lot to get spacing correct at various places, particularly on the base board. (my stations are at 100 centres, ply is 8 mm)


As for supplying others with bodies, I am under no illusions as to how many people will actually stump up money. Out here we have an expression which comes to mind whever anyone asks me if I can make them something - "Talk is cheap, money buys the whiskey!"

I want the wheel arches to look like this car. Over the years the wheel arch lips on original 70's seem to have varied quite a bit.

My next project is going to be a 4'x8" cnc router table.

Nice job so far. I've built lots of plugs in my day (boats) and a solid understructure makes a huge difference in the quality of your final mould, I've seen many try and cut corners to get done quicker or cheaper, and it either cost them more in the end, or quality was lacking.
But you are on the right track for a blug you's be able to pull miltiple moulds off of, if you were planning to go into production.


Schrodinger - 14/5/07 at 09:30 AM

I've been watching this progress and am very impressed with the project.
Any progress Fred?


Fred W B - 14/5/07 at 11:18 AM

Hi Keith - Thanks for your interest.

Progress seems very slow, but I do feel that I am steadily getting somewhere.
I have now got the radiator exit duct and the cockpit edges finished (except at the nostrils), and am fitting foam blocks to the nose and LHS of the car.
I will post some more photos soon. I prefer to post several pictures when I feel that I have made some significant progress, rather then one picture every week, as then it looks like I'm just bringing the post to the top again and again.

Cheers

Fred W B

Fred W B - 8/7/07 at 04:13 PM

Still plugging along, and have finally managed to wrestle the shape of the rear air intake ducts into submission. This has been the worst bit to get right so far, and one I have been working on a bit, leaving to do something else, and then going back to. We didn't get this area right in our computer model, so I had to go back to old fashioned first principles, shaping by eye from the model and photo references, and using wood and cardboard templates to get the left and right sides to match. It's still not quite finished, still pending the application of the hard skin.

Trust you will find the attached photos self explanatory. I bent the conduit to shape by hand in a vice and with lots of trial and error.

Cheers

I trust you will have room to save this 'intermediate' work of art once you have used it to create your mould! It's beautifully crafted.

Taking your time and spending the money/effort to make this phase as good as possible will save you so much money/time/hassle later on. (Said as someone with painful experience behind me. )

I can't wait to get started on my next one.

Ahhh the words of pure wisdom.... shame I'm making all the mistakes you did lol.

What rates do you charge for consultancy? I think I need some!


Fred W B - 18/8/07 at 06:05 PM

So back to the business at hand....

I have now got pretty much the whole of the body pattern framework covered in foam, and the hard edges such as the cockpit edges etc made up.

Won't be starting with the hard skinning for a while yet though, as I am currently working on the extreme rear of the body and the front 250mm of the nose still has to be done. I am also not happy with the contours we did along the top of the doors, into the top of the front wheel arches, so I have some reworking to do there.

I want to get rid of most of the foam dust before I get the sticky stuff into the workshop.

Cheers

@ peteff, that's because it kinda is, suprized me how long the tail is when I was in a GD t70 first, the rear is longer that my strikers bonnet....

@ Fred

Once again BIG THUMBS UP!!!

permission to speak freely, SIR?

the problem with the doors to nosesection is that it looks like the door is a section and the wheelarch is a section beause of the angle of the upwards curve at the section where the wheelarch begins, the flat piece of the door suddenly takes of as you move your eyes towards the arch.

maybe it would be an idea to make the doors and arch look like one piece

I can imagine that when you take a picture of the side of the car it looks like the car has three sections
front to arch, arch to rollbar, rollbar to rear.
you can try to make that 2 sections nose to rollbar, rollbar to rear.

more like this, I don't know about originality but it looks good



disclaimer: I may very well be that I talking a pile of poo that didn't even come from where it should.....

Fred W B - 31/8/07 at 02:13 PM

All right - look at the length of the tail of the body aft of the rear wheel arch. It's most apparent if you look backwards along in line with the top of the rear tyre.

I could not understand that no matter what I did with the blend of the rear lower section into the rear panel with the holes I could not get it to look right.

As far as I can tell from scaling photo's I have to shorten my plug behind the rear arch by about 160 to 170 mm

sgraber - 31/8/07 at 03:31 PM

yes, I see it now too. Very subtle indeed.


adithorp - 31/8/07 at 08:10 PM

So why would the models be wrong?

There wasn't a special body work for some events was there? Not sure about now but endurence race cars ran different bodywork for Le-Mans due to the sustained high speeds down the strieght, back in the '80s when I used to follow it.

well yes, that's true as well - with CAD though, a mistake means usually tweaking a few spline co-ordinates and examining the difference, it's the fact Fred's taken the entire back end off again and re-sculpted it - would be heartbreaking having put so much effort in the first time!

well yes, that's true as well - with CAD though, a mistake means usually tweaking a few spline co-ordinates and examining the difference, it's the fact Fred's taken the entire back end off again and re-sculpted it - would be heartbreaking having put so much effort in the first time!


yep pretty much what I do..... but by doing it in the flesh we can also see the change in the flesh.

Also the satisfaction when you have put it right is quite nice.... I almost forget the pain of doing it for the 4th time.


BTW Fred, top job... keep up the good work.


Fred W B - 17/11/07 at 05:45 PM

Thanks for the comments guys.

Some more progress to report. I am now happy the rear panel is ready for skinning. All the openings have 1 degree slope returns and the edges are all radiused.

Moving to the mid section, I have mocked up a windscreen template in hardboard in order to establish the angle of the windscreen recess.

Having reworked the LHS, I am now much happier with the blend into the top of the front wheel arch and the profile of the top of the door. Still have to finish off and do the RHS.

We have been discussing the merits of CAD verses old fashioned trial and error following the rework I did to shorten the tail. Here we see the other approach.

Andrew volunteered to do some more work on the nose of the car. This is the refined front view drawing, which was used to generate a tool path to cut the front 250 mm of the nose on his home made 3 axis CNC router. The part was cut in 3 sections which were glued together.

That 3D router certainly does a nice job Fred - what material is it working with?


Fred W B - 17/11/07 at 06:49 PM

Hi Raz.

The material you see there is polyurethane foam, with a density of about 32 kg/m2. That density is not ideal, heavier would be better.

so when are we going to see it in primer?


Fred W B - 5/12/07 at 06:03 AM

Still quite a bit of work to do before I get to the surfacing stage. Still need to complete the reworks on the RHS. and touch up a few other areas

I am now happy with most the shape, just want to do a bit more work on the rear air intakes, I now think they need to be a bit smaller and lean back less. I think I have cut them too far back into the rear wings, so they are much bigger than they should be. I also want to add a bit more "bulge" to the inside side of the front wheel arch bulges, above the tops of the front wheels

I have still not yet personally seen a real (or replica) T70 spyder in the flesh and trying to get the proportions and some of the details more or less right from photographs has been driving me crazy, not helped by the fact that the model I started with, the original 60's built cars in period (and now), the Lola Heritage continuation series cars, the GD / RCR narrow shell replicas etc are all slightly different in certain areas to each other.

I have had a lot of help from some of the Lola owning guys on gt40s.com who have sent me photographs and measured dimensions from original cars and bodywork that they own.

Fred - I am extremely impressed with the quality of work and effort you are putting into this project.

Seeing the nose done on the 3D router gives rise to the question:

If one where contemplating a similar project on some other car would it be worthwhile getting the shape cut on a 3D router using high density foam or doing it in frames as you did?

One advantage would be that re-designs would be a lot easier to implement.


thomas4age - 8/12/07 at 03:34 PM

Hey Fred

home made portal type CNC router, that sound very tasty!

@Ivan, that's a way of doing it,
but acces to a big cnc portal type milling machine isnt very easy, I know at least one who did it like that, the body plug was milled at a shipping yard on a 3d portal CNC mill, that normaly is used to make plug's for hulls of 100K+ costing sailing yachts, the total cost for tooling the bodyplug was somewhere in the region of 15.000euro's

so unless your neighbour has something like that standing in the workshop and likes lots of beer tokens.... it wouldn't be very locost.

Fred W B - 8/12/07 at 03:34 PM

HI Ivan

If you have access to CAD and CNC machinery at the right price, it will be MUCH easier to get the shell drawn completely in CAD, and then CNC cut in one piece (or sections) in foam. Nowadays, they cut the foam a few mill undersize, then apply the surfacing filler and recut the plug final size, so then just have to wax and take moulds.

If the CNC you have access to is a router with limited Z height I would suggest rather than cut thin ribs and fill between than manually, have foam sections cut in say 30 mm slices, glue then together and then blend the contours together.

With any task that is new to you, you only really know how to do it properly once you are finished! If I was doing this again, I would spend more time getting the CAD model to be exactly what I want, by comparing it at all angles with photos of actual cars. If you are doing an original body that will not be a problem.

Cheers

Fred W B

My plans at the moment are for a home made CNC mill roughly the same size as the workshop (the workshop is having parts built in specifically for the CNC machine)

Chances of success - 50/50 I reckon, it'll either work or it won't

To pay or do it yourself raises an interesting conundrum when you're retired. the conundrum being whether to work as consultant or at something that you're realy good at and pays well for a fraction of the time that it would take you to do the job and employ an expert to do the building - the alternative being to do it yourself that could be a real shlep and take years instead of months to do.

One of our local glass fibre firms for example makes some of the most beautiful car bodies for the racing and advertising industry from scratch at a cost for buck and moulds for what would take me around 4 months of Consulting to earn.

Bodies he has made recently include a Porsche 917, Audi LMP, Mustang, Formula 1 Clone etc.

Why I'm interested is I would love to do a Porsche 904 or 906 or Renault Alpine a110 replica and am puzzling out the best way to go about it.

No brainer then Ivan, by the time I have a set of moulds I recon I will have spent at least R15 000 on materials, and that includes getting the CAD, Router, and CNC time and the foam material for FREE, not to mention the maybe 500 hours I have spent on the pattern already.

Some sources quote 1000 hours for a car body pattern done the old fashioned way, and I can believe it

I have been working on the RHS, to get it the same as the reworked LHS. Where I have deviated from the original routed stations, I have to make templates to check symmetry of the profile on the LH and RH sides.

Fred W B - 7/1/08 at 06:22 PM

You have to be sure to keep the template vertical when checking, particularly where the body slope is steep, hence the spirit level attached to this template.

[img][/img]


Fred W B - 7/1/08 at 06:23 PM

In order to keep the body as symmetrical and "square" as possible, I check everything back to a horizontal reference plane I have across the back of the cockpit. Have to be careful you don't loose the centerline on the pattern!

[img][/img]


Fred W B - 7/1/08 at 06:23 PM

Here you can see that at this point I determined that I had had to bring the highest point of the RHS front wheel arch hump up another 3 mm.

Fred W B - 7/1/08 at 06:24 PM

Have now started adding a bit more "fat" to the rear wheel arch humps towards the center of the rear deck.

Finally starting to feel I have now broken the back of most the body shaping.

Fred - watching your progress amazes me - you are certainly going for perfection and getting there.

It reminds me of an old work colleage (a surveyor believe it or not) who's favourite expression was "we are not grinding crankshafts here" as an excuse for mediocre quality work or taking shortcuts, and in many cases it was valid. However that definitely doesn't apply to what you are doing and I am sure that your "grinding of the crankshaft" will show in the end result.

Keep up the good work - you are an insperation to many of us.

Dom9 - 10/1/08 at 09:53 AM

Hi Fred, I have hovered on this forum for quite a while but have spent the last few years working away from home. So I never signed up here or indeed had the space to work on my own project.

I was offered a Group C Jaguar XJR-9 body in GRP a few years back, but I had to move house and so couldn't commit to the project and I also remember in one of the UK kit car mags a few years ago, another Group C/ Le Mans style body in GRP being sold for only £600 if memory serves correct...

I haven't seen anything (except maybe the Ultima) like that for a long time and so I have been thinking a lot about getting a nice, authentic die-cast model in say 1/10th scale and having it drawn up in AutoCAD (my missus, Lou, is a CAD draughy) and make the plug exactly as you have done in the garage.

I would really love to design the whole car, from spaceframe and suspension through to bodywork and own my own Group C/ Le Mans/ IMSA GTP replica!

This thread is a real inspiration as is Andygtt's work, which I have followed (quietly) on Pistonheads since he first posted there. The only thing that scares me is the cost and the time involved... Despite being an engineer in the oil and gas industry, having previously worked for Lotus and Ferrari, I would still be worried about trying to build a body from scratch.

If we are ever in town, and I have promised Lou we will go to SA soon as my grandparents were from Cape Town, I would love to come and see the work you have done.

Hopefully I will have the time and passion to do what you and Andy have done, over the next few years.


Fred W B - 10/1/08 at 06:27 PM

HI Dom

Thanks for your post. I would be very pleased to show you what I am doing, if you ever end up in Port Elizabeth. If you are planning a trip to SA, driving by road from PE to Cape Town (or visa versa), via Kynsna is reccomended.

Anything is possible, if you persevere. As an engineer you already have the problem solving skills required. Before I started this, I had no practical experience in any car designing or composite building skills.

As I said in another post a while ago, once I've decided what I want to do I:

Find out how to do it - books, internet, speak to people.
Get what I need to do it - tools, materials.
Start doing it!
Solve one problem at a time.
If you get stuck do something else for a while, then go back to it.

So just go for it

Cheers

Fred W B

This brings to mind the quote attributed to Nevil Shute who, as well as being a notable author, was firstly an aeronautical engineer. He said:

"An engineer is a man who can make something for five bob that any bloody fool can make for a quid!"

I agree wholeheartedly with Fred's thoughts here. Knowledge of the technical details of building a car are less important than the mindset necessary to enable you to acquire that knowledge.

I suspect that some people enjoy the problem solving aspect as much as (or maybe even more than) driving the finished product.

ghetto_eddie - 16/4/08 at 03:28 PM

Fred,

I am building a body in a very similar way to you... even down to the little KD (modesty/whatever you call them) blocks holding the ply together..

But one big question... how the hell did you secure yours together? i started to assemble my buck the other day and realised my drill is too big and hence doesnt fit in enough for me to sink the final screw (of the 3) in the blocks!

My only solution so far is a 90degree drill adapter... but would be interested to see how you got on with this!

Regards

Edd


Fred W B - 16/4/08 at 03:42 PM

Hi Eddie

I made sure that I worked from the first station outwards, so you were always working away from the previous panel. Secure that panel, then move onto the next. You have to think the assembly process through to ensure you can get in where necessary. Put all the joiners on a panel before you add it to the buck where possible for example.

Where I sometimes had to go back in, I had to cut away the second panel back enough to get a short battery operated pistol grip style screwdriver in. Or some times I could use a very long adaptor made up from 1/4" drive socket set bits, through access holes drilled in the stations etc etc. Use a large "spade" drill

All the best with your project

Cheers

Fred W B

ghetto_eddie - 16/4/08 at 04:11 PM

Thankyou Fred for the quick and helpful reply!

I shall see tonight if my 90 degree adaptor idea will fit in... if not i shall procede with the method you outlined above!
All the consideration i put into this build... and i overlook the smallest of things!

Edd


Fred W B - 16/4/08 at 04:52 PM

I left out my "trick" , which was to put the longitudinal stringers 200 mm, far enough apart to fit in the pistol grip driver.

I put the connector blocks (with the two screws) on the transverse stations first, as I build up the framework longitudinally, then when the stringers went in I just had to put the third screw into the stringers

I am sure the right angle drill will work too, though just mayby a bit difficult to "muscle" . I stopped counting once I went past 1000 blocks x 3 screws each!

Cheers

Fred W B

[Edited on 16/4/08 by Fred W B]


ghetto_eddie - 17/4/08 at 08:00 AM

Fred,
I developed a similar method to what you mentioned, assembling the blocks on the "stiffeners" first, and now just to assemble... but unfortunately my sections are 175mm apart! shot myself in the foot there!

ime currently on 400 blocks pre-assembled onto my stiffeners! FUN

I bought my right angle drill adapter last night... shoddy piece of Cr*p but it may just work!

Sorry for clogging up your thread!

Edd


Fred W B - 25/5/08 at 05:51 PM

It's been a while, but I have very busy climbing up the learning curve of laying up and working off fiberglass. Having now consumed the majority of a 25 kg drum of resin, I have about 80 percent of the pattern covered in a generous layer of resin and CSM.

As I was warned, this is messy, tedious and unpleasant work that definitely requires a "knack" to be acquired. It is the most difficult task psychologically so far on my project. I am definitely very glad I spent as much time as I did getting the shape to my satisfaction before I started with the resin.

I attach some detail photos. As always the edges and returns take a lot of time. As you can see the pattern looks a lot worse for a while, before it starts to look better again. At the moment I am grinding back obvious high spots and overlap joints with a flexback wheel in an angle grinder, and reworking occasional "soft" spots in the surface, where I caught an airbubble in the layup. I'm looking forward to getting this stage finished so I can get onto the final smoothing of the surface with a long board etc etc etc

Cheers

For the last three weekends, and also some weekday evenings, I have pretty much done nothing else than graft in the garage, in order to get the damn fiberglass skin finished. Now every square centimeter (except under the nose) is covered, some of it worked off fair, and I have actually started applying some filler - Yay.

I couldn't resist working off the first section of filler I applied and I'm very happy with the way the surface came up. This is after just one application of filler.

Have now got a layer of filler worked off over almost the entire pattern. Not much to see though, just how many pictures of sanded filler can you all stand?

i think there are 2 types of kit car builders - those who make bits for the car and those that buy bits - personally i prefer the making bits type - because it stimulates the mind the make better things- after all if you can make something like this - you could make just about anything given the time and patience

Random Thoughts while shaping

I haven’t posted much progress detail lately. The work I’m doing now doesn’t show well in photos, but the shape and surface is getting better and better. I prefer to post details of what I’ve done, not talk too much about what I’m still going to do. I saw on another car building forum a guy posted nice renderings of a car body he was going to build. He gave himself a month to build the plug. After two weeks he had a lump of hacked about foam, and he gave up. Sorry mate – It doesn’t work like that.

All this sanding means you have a lot of time to think while toiling away in the garage. Making a body pattern single handed is a silly amount of work. To do this I think you do have to be determined, some would say bloody minded. It reminds me of when I was cycling competitively, and later racing karts. Sometimes while doing the activity (cycling – while feeling bad and just just hanging on the back of a bunch, karting – being nerfed off the track, or having other issues during a race day) I would think to myself – “this is madness, I’m not enjoying myself, I’m going to give up”. But then at the end of the day you see you have finished a bit higher up than last time, and you feel better, and so you give it yet another go. Having like minded mates to chat/drink beer with after also helps a lot.

I have seen a couple of references that state doing a body pattern the old fashioned way takes maybe 1000 Hours. I reckon I am averaging at most about 10 hours a week on the project, so that would be two years. Currently just starting the 20th month of work on the pattern and I hope to finish this year still, so that 1000 hours seems about right in my case. I read in USA magazine “Hot Rod”'s paint and body issue that rod or muscle car high end professional paint jobs may have 200 to 300 hours of block sanding alone in them – and that’s on an existing car!

I try to concentrate on just the area I am working on, without thinking about the all the work yet to do. When I get despondent I look back through this thread and see how far I’ve come, and that improves my resolve to keep going, as does the positive responses from you guys here.

Experienced builders might smile at the notes below, but I put this down for others who may be considering a similar project. Maybe they are just notes to myself:

There is no “easy way”

Don’t agonize over how to approach or do something. Just start, and move on from there. You may find that eventually the first thing you did has been changed/replaced, but at least you started.

Get each stage as good as you can before you move onto the next. It’s easy to shape wood/foam, less easy to shape GRP, a pain to correct stuff at the body filler stage. Getting it absolutely correct at the drawing stage would be first prize.

Don’t expect to get every section 100 percent the first time. Get it good, do another section, work round the car, when you get back to it you can get it better.

Even when you don’t feel like it, or just have a little bit of time, get in the garage. Things don’t get built if you aren’t in the garage. Even if you just tidy up a bit, you will do something.

Do everything to the standard you want. If it bothers you every time you look at something, rework it.

If you get tired, or find yourself rushing to finish something at the end of a day, stop. Do it next time. You will make mistakes and have to redo it if you don’t.

When you think you are just about finished, you aren’t - The last 10 percent takes 90 percent of the time.

Anything can be fixed / reworked.

Cheers

Benonymous - 6/8/08 at 01:05 PM

Hi Fred, I'm not only impressed with what you have achieved but also with your work philosophy. The car you are building comes from an era where design was functional but also aesthetically pleasing. Your ideas about carrying out the work also come from that era of patient craftsmanship.

I know for a fact that one day I'll see a gleaming Lola twinkling in the sunlight on this thread. I don't care how long it takes.

Power to your sanding arm mate!


sgraber - 6/8/08 at 02:53 PM

Thanks for that philosophical musing Fred. You've dredged up a rush of memories on my part! I would like to just stand beside you in agreement on all of your above mentioned points.

That part about just doing a small thing every day even when you don't feel like it, that is a core value that will see you finish this project and it's the one trait lacking in so many people. Dedication. You've got it in spades! Congratulations.

G.


Fred W B - 22/12/08 at 05:42 PM

So, an update!

I have not been making progress as fast as I'd like, getting a consistent uniform shape and radius on the edges around all the openings has been taking ages. I have got through over 50 kg of body filler so far. I am now working with 120 grit paper and trying to get up to a dark ABF guide coat that will be the last iteration before the primer surfacer can go on.

Currently I am pretty happy with all the top, side and rear panel surfaces, as well as the cockpit edges. The rear wheel arch edges are pretty much done, as are the edges of the "hip" ducts. The internal surfaces of these still need some more work, as does the front wheel arches and the edges of the openings in the front of the nose. After that the only major job left is finishing the inner faces and edges of the radiator exit duct.

I attach some photos

Cheers

I remain in awe of what you are achieving - it's something I would love to do but know I don't have the perseverance to ever reach your standard of workmanship I know I would eventually take a short cut and spoil the job

I'm much better at mechanical things that don't need the endless fettling and repetition to get them right.


smart51 - 22/12/08 at 07:54 PM

I am in awe. Seriously, if mine gets to look as good as yours does now, I'll have finished, not be thinking of finishing.

I've been on this site for a couple of years now and have only just stumbled across this post. I've just spent about an hour reading it and taking in all the work you have done. And all on top of having a job and normal life to go with it. You must be a very stuborn person! I only wish I had the patience and the drive to build something to half the quality that you are doing. Keep up the good work. No doubt when you are finished I'll still be reading and wishing!

Fred W B - 4/1/09 at 06:44 PM

Being on leave at the moment, I have been able to make quite a bit more progress.

The front wheel arch edges are almost finished. Here you see the arch opening shape template (the spirit level is screwed to it) and the lip profile checking plate.

In this first shot you can see that the blend of the lip to the fender still needs a bit more work, although the flash does seem to exaggerate the effect.

Although the pattern is solid enough that I can sit on it, it is difficult to reach down far enough to work in the bottom of the rad exit duct. I had to make this platform to kneel on. Its hard work sanding at the full stretch of your arms!

seansverige - 9/2/09 at 05:53 PM

Hi Fred

stumbled across this whilst doing some online research. First off I would like to congratulate you on what you've achieved - truly, truly amazing: you seem to have taken the hardest road possible from your 3 axis measuring jig onwards, and look close to completion - many others would have fallen by the wayside.

I'd like to offer a couple of observations that are too late for you but might prove useful to anyone reading this thread and is inspired to copy your example - I think these approaches could be applied to any subject.

When I read that you were working from a model my heart sank - models can vary significantly from the reality. This can be unintentional, such as the case with the rear overhang that caught you out - but I have to say that other than that you've really pulled it off. I don't know whether the different rear wheelarch on the other model is based on an actual variant or simply a liberty taken. It also use to be the case that a fair bit of plagiarism went on in the mainstream industry so the first guy to model it makes the tail a little too long, and this get copied in subsequent variations.

Variances can also be deliberate: smaller features can look out of scale when modelled accurately and in fact need to be exaggerated slightly to look right - and this effect increases as scale decreases. This is less of an issue with the more organic shapes like the Lola, but a problem with more complex forms such as the Audi TT's wheelarches (in this case complex means surface breaks and detail.)

The modelmaking scene has really taken off so if possible it's worth investing in a slightly more expensive but hopefully more accurate model. At the extreme end, I don't know how amenable they might be to sharing information but, on the assumption that actually purchasing one of their models is out of the question, contacting a high-end modelmaker such as John Shinton (www.johnshintonmodels.co.uk - who in fact makes a 1:8 T70 Mk3B coupe) might yield some useful info or tips.

I would also look at other modelmaking sites - there are some useful sites and forums out there. There are an increasing number of websites that collect blueprints (such as www.the-blueprints.com) - these are generally for guys building computer models, but there maybe some useful info there, especially for the more recent stuff.

I think you mentioned that you've never seen a T70 in the flesh - or at least hadn't when you started the project - making what you've achieved quite frankly jaw dropping. Historic racing is the fastest growing motorsport segment of late, and a quick search turned up the Zwartkops 9 hour revival race at Kyalami (don't know how much of a trek that is for you) - and the entry list DID feature a T70, although I don't know what variant. Even at the biggest events such as a Goodwood, paddock access is excellent compared to conventional motorsport meeting.

Having found this thread, I've registered and will be checking back on your progress - keep up the excellent work. Good luck!

/sean


Fred W B - 9/2/09 at 07:02 PM

Hi Sean

Thanks for your comments and kind compliments.

As you say, it seems to have been a long hard road, and I certainly have a much better understanding of the T70 shape now than when I started. As for working from a model, it was the only reference I had. I don't know where I would have started from without it. As for how accurate the shape is, I will really only know if my shell ever stands next to a real one. But which real one? The GD/RCR replica is based on the 3 continuation cars that Lola licensed in the early 80's, and that was quite a bit different to the original 60's cars in some areas. I understand that the GD/RCR replica shell is 4" narrower than an original.

Also, as I have stated before, I have deliberately done some details differently to the originals. I've got to the stage now when I have to put the pictures away and just get the damn thing finished and looking good to me. If I was trying to do an absolutely accurate, indistinguishable from the originals, copy I would have been a gibbering wreck in a nut hose by now.

That said, I'm not sure if I am really looking forward to when I will be able to get it onto wheels and push it out into the sun for the first real look, in case I am disappointed. I have read that the guy who did the pattern and moulds for the really accurate Kraftwerk 917 replica went through everything I have done, and then when the first body was out the mould and built up, it did not look right to him, and he went though the whole thing again, modifying the first set of panels and making new moulds.

But then, looking at various website's where guys discuss the various "high end" expensive replicas of some classic sports racers that are available, there's always someone who recons this or that is "wrong", and most people are happy to accept.

As you suggest, last year a real T70 spyder did make the trip out here with the David Piper circus to do the Zwartkops (Pretoria, 1100km trip for me) and Killarny (Cape Town, 800 km trip) races, but I was not able to schedule a trip to see it.

Their are 2 or 3 T70 Coupe replicas/mould sets in SA (I think originally based on a Maurader shell) but no spyders, at least to my knowledge.

Another point, in the now going on 6 years since I started this thing the amount of info and pictures available on T70 spyders on the web seems to have increased dramatically, unless it has just become more visable to me as I became more aware?

P.S - I dont intend to put "Lola" badges on the car, when people ask what it is, I say its "inspired by" a Lola T70 Spyder.

Cheers

Fred W B

seansverige - 10/2/09 at 05:16 PM

Hi Fred - thanks for the swift response.

I was just throwing out ideas that might be of use to others following your example and (just to be clear) not in any way challenging your approach or wanting to imply that none of the suggestions mentioned hadn't occurred to you - I'm sure you have plenty of hard won knowledge to impart. Starting with a model was the best way, but I guess the basic principles are to question everything – as you did with the rear overhang (it was this that prompted me to write) – and cross-reference data from as many sources as possible to get a levelling effect.

You do yourself a disservice stating you're not being absolutely accurate – the attention to detail and quality of workmanship belies that and I personally applaud your willingness to tweak things to your own satisfaction, which is surely why you're doing it in the first place?

As well as all your other challenges, there are some inherent in your choice of subject matter – with low volume race-bred stuff like this I'm sure very few were completely alike. These guys were concerned with winning, not historical record, and in a pre-digital era only documented as much as they needed to to get the job done, so reconstructing the picture decades later is open to interpretation - and that's before we consider any changes made in that period between them being cutting edge and classic, when they were simply old cars; finally, as you say, there's the issue of 'continuation' models...

I would say you're correct - in the broadband age more stuff is out there, and Lola's 50th anniversary stimulated that further, but there were a few good books about. The point about the modelmakers was that with someone like Pierre Scerri (the guy who did the 312 B) – his chosen subject matter is now probably more comprehensively documented than it was when first designed and built; how willing they'd be to share that info is another matter (if not already done, surely books could be written from the research material generated?)
In terms of actual replicas, I think this term covers a multiude of sins: many of replicas should be called lookalikes, but then categorising your project with some of these is frankly an insult to you, but that's a whole other discussion. It's not just the internet that's changed things – Goodwood FoS is only 15 years old and the Revival considerably younger; a quick trawl through Flickr the following Monday can yield useful data.

Look forward to seeing photos of the rolling chassis in the bright SA sun and hopefully the fact that this is your interpretation of a T70 means you're less likely to be disappointed.


Fred W B - 10/2/09 at 06:32 PM

Thanks Sean, and no, I wasn't taking any offence at all, enjoyed your input.


quote:

Interestingly enough, one of the most useful references I found was a scan of a scale 3 view line drawing published with a article about the car in a car magazine when the car was new. The look of the drawings suggests that the author might have had access to the original lola drawings.

It was very kindly sent to me by a guy in Belgium who saw my project on here.

Some good news out of the commercial crisis!

I haven't been able to get any time on the car for several weeks now, due to some other things keeping me busy, but this weekend managed to get back in the garage.

You know how retail establishments only know how to put their prices UP, while those of us in engineering / manufacturing / construction have to instantly adjust selling prices due to raw material price changes when commodities and petrochemical prices soften?

Today I went to buy some more paint rattle cans, to find the price is now two thirds of what I have been paying in the past. I nearly fell over. As we know all economic activity has softened but its nice to see a price reduction on the retail shelf when you are taking money out of your own pocket.

Hi Blue

The plan is a deep blood red and silver, just like the single seater below. Sills will be the silver below the beltline as well, running into a gulf GT40 style "moustach" . Stripe will be a broad centre stripe with two smaller stripes each side, like the second picture below, but with wider side stripes, more like the third pic, but here maybe too wide. Also here the red is too maroon for my taste.

Maybe now you are sorry you asked, but I have been thinking about this a lot......

Hi Chris

Don't know if your would call it a "big" step, but next is spraying the surfacer primer. Currently I have sanded the last guide coat off a good three quarters of the body, while it looks lousy I am happy that I am finally getting the surface good enough to start with the primer surfacer.

A few people who have seen what I am doing have commented that they would have gone with the primer surfacer long ago, but I wanted to get the surface good while still in filler, rather than turn lots of the expensive primer surfacer into dust

No doubt about it Fred, you're a stayer! What was your best profile as a cyclist? I'm betting a mile-eater or a climber rather than a sprinter

Thanks Ben

Good call on the cyclist type, being of small build I was never a "power" cyclist, so not a sprinter. If I could stay with a bunch on the flat I was always able to easily stay with on the uphills, so guess I would be a climber then

Fred W B - 27/6/09 at 04:00 PM

So I've got the entire pattern flatted with 120 grit and the mission for this weekend is to start getting the primer surfacer on. I've been able to clear the weekend of all other commitments. I'm finally looking forward to some concrete progress!

I've collected together the materials, spray gun, lots of wet and dry paper. I have my measuring scale. I've taken advice on mixing ratios. The primer surfacer requires a catalyst, some thinner and I have been advised to also add some pigment to the primer in aid in seeing the shape when polishing it back.

By 9.00 am Saturday the pattern is wiped down and I am ready to start mixing the first batch. I reach for the catalyst, only to find I haven't got it!. Apparently I must have left it on the supplier's counter when I picked up all the materials, or lost it on the way home. In spite of searching my car, tidying the entire garage and searching under every bench in case it fell and rolled out if sight I fail to turn it up. And no way to get any more until next week. I am now not very happy!

Oh no Fred that sucks - at least the rugby result was a small consolation.


Fred W B - 5/7/09 at 05:52 PM

Finally got the first coat of the Durabuild surfacer primer on.

Made a few mistakes, I thinned it with about 25 percent MEK and sprayed it with an syphon gun with a 1.5 mm tip. Battled a bit to get an even build, particularly on the top flat surfaces, but otherwise it went very well, apart from me dragging the air line over the wet surface on one of the door panels and also getting some dust on the surface in a few places. I really should have started from the center and worked out, but in my enthusiasm I did it the other way round and found it difficult to get to the center of the front and rear clip surfaces.

The pictures are with no flatting at all yet. Some mates have been round and have made encouraging noises, and I must admit to be feeling pretty happy with the results. I may just be having a beer or two at the moment!

Now to flat it back and put another coat on. I have now bought a gravity feed gun and will try a 2.2 mm tip, which apparently is much more suited to this work

Cheers

hi there,

any updates cant weight to see how you are getting on


Fred W B - 11/10/09 at 05:35 PM

Hi Cee

I'm still sanding, working now on a third (and final!) coat of surfacer primer.
The photo below is of 240 grit surface wiped over with a wet cloth to see the surface.

Just starting to move from 240 to 380/400 grit. Have given 600 a go on a small area and the results are most encouraging

Havn't been putting pics up because you can't see much progress, was thinking to wait until I have got the pattern up to polish stage but as usual some areas needed touch up and reapplication and this holds up progress on the big picture

Something else I have learnt - It would have helped (me, at least, I'm sure the pros have it sussed) a lot to stripe coat the edges and internal surfaces of recesses with the surfacer primer on a brush before spraying the bulk of the pattern

Cheers

In this photo (of my nephew checking to see if I've got that wheel arch lip blend exactly right....) you can see what the pattern looked like with the second coat flatted back.

Went through in a couple of places, and as the overspray goes everywhere I ended up giving the whole thing a third coat. The "tide" marks are because each pot mix is a slightly different colour depending on how much pigment I put in.

You would think so, wouldn't you?

Since the last post the whole pattern has been:

sanded with 360 grit
sanded with 600 grit
sanded with 800 grit
sanded with 1200 grit

and just this weekend I have started with the rubbing compounds. I have been trying to wait till I get the whole thing up to wax level before I post again but here is a teaser pic

Fred W B - 7/2/10 at 05:23 PM

Believe it or not, I have finally put down the sanding blocks, put the cap back on the polishing compounds, and stepped away from the car.

The whole surface of the pattern, including in the recesses and returns has been polished with coarse and then fine cutting paste. As the gloss comes up as you polish you see some areas where the 1200 has not taken previous grit scratches out so I go back to 1200 grit and then polish again etc, etc, but finally, finally, I reckon the pattern is FINISHED!

Next time I work on the car, which will be in a couple of weeks time, I will start with the marking out for and making the parting fences for the moulds.

I include some gratuitous photos. It looks a bit tatty with the three different colours showing but in hindsight it was very helpfull that I pigmented the first coat of surfacer primer black, the second dark blue and the third light blue. As you sand back you can see where you are, when you get to the black layer you stop! This was a pure fluke, due only to the pigments my supplier had in stock at the time and not some clever pre planning on my part.


Cheers

Fred, as someone who has been there and hopes to never be 'there' again I can only say congratulations on getting to this milestone. Your dedication and perseverance are exemplary and the photos of your work say everything else about your skills.

Now, take a short break and get on with the moulds! But that's another day. Relish this one as I guarantee that as you look back upon your lifes accomplishments, this is going to rank up there with the best of them.


alistairolsen - 22/2/10 at 02:23 PM

I've just read this whole thread and I can only say its truly amazing. Ive build things using this technique in the past which while the shapes were similarly complex, the items were tiny. I am in awe of the dedication and the time spent on this and I hope you enjoy your car for a very long time.


Neville Jones - 23/2/10 at 05:31 PM

Paint/surface that plug with black, then polish it. Put it under fluoro lights parallel to the c/line, look at the reflections.

If you're happy with what you see, THEN make the moulds.

From someone who has done it far too many times.

But you haven't looked at it in polished black, have you? Black will magnify the wobbles many fold.

Take the time to do this step, you won't regret it, and it's time well spent, and insignificant compared to the whole project length, but the most important.

So the next steps were to get the parting lines and fences done for the door perimeters . These were laid out with the aid of dimensions and pictures supplied by the very helpful owner of an original T70 in America.

Then 10 repeats with wax on both doors.

Small gaps between the fences and the pattern were filled with kids plasticine

Fred W B - 24/5/10 at 05:03 PM

Then on with the first door mould. I put on two coats of tooling gel and laid up 1 x surface tissue, 1 x 300 gram and 5 x 600 gram layers. Double thickness on the flanges.

Took me a while to get the "knack" of laying up. I put on two layers at a time. I let it rest for a good few days or a week between each session. The trick is to get all the bits of mat tailored exactly to fit prior to catalyzing the resin. I also prepared two or three small mixes, to use in one session, rather than mixing all the resin at once and rushing to get the whole thing done before it went off. The surface area of the door is 0.8m2. The flat bits are easy to do, its the fiddly bits on the returns that take time.

I then added some plywood bracing. I bonded only the longitudinal pieces to the mould, the transverse pieces were secured together and to the longitudinals with screws to hopefully eliminate "print through" of the transverse ribs.

[img][/img]


Fred W B - 24/5/10 at 05:07 PM

And now this past weekend I released the first door mould. Took some determined pulling with the aid of some friends but it eventually released cleanly, with no damage to the gel coat.The mould surface looks good enough to make parts (that will be painted) straight away with no further finishing. Lines are true and it appears "print through " is not a problem. The rough looking edges in the pic is just where some plasticine is still adhering.

Now to make up the wooden flanges for the door inner returns and the insert box that makes the return where the hinges are and I can then actually make a part!

I have removed this mould now as I want to cut the door sections out of the pattern once the doors are made to permit easier access to the top sections of the front and rear clips as I make those moulds. The forward facing sections of the rear section will have wood inserted to enable me to make the mould section for the return on the rear clip that is "in the door gap".

Cheers

Well done, well done indeed Fred! Wow seeing you go through this step does bring back some great memories for me. I've always told people that the hardest part of a scratch build is the bodywork. But it can also be the most rewarding when it turns out well.


chrsgrain - 25/5/10 at 08:38 AM

Wow - cool.... must really feel like you're getting somewhere now. The mould looks awesome.

If you're going to chop the plug about, would it be worth taking a spare mould (or two) from it before you start the dismantling... never know when it would come in handy, or who might be prepared to pay for it?

Chris


seansverige - 25/5/10 at 10:11 AM

Fred - just caught up on the latest, and continue to be amazed by your diligence and craftsmanship.

I'm sure the sanding phase seemed to go on forever but looking at photos of the polished buck, it seems to have been worth it - and I think I may have to check back a little more frequently as it looks like the next stages will fly by in comparison.

all the best, sean


Fred W B - 26/5/10 at 05:01 PM

Thanks for the kind responses guys.

quote:

worth taking a spare mould (or two)?



As for making spare moulds, while they would be nice to have, extra sets would be a considerable investment in materials (the moulds are 3 or so times thicker than an actual body would be), not to mention time. Also moulds are extremely bulky to store. Another consideration is that once the first car is built up and standing out in the open on wheels, some aspect of the shape might look completely wrong, and will require rework/mods to a mould. Provided you have a panel, you could always make another mould from that panel, if it should be necessary.

As for selling moulds, the hope would be that I might be able to sell a few shells, and if I was to sell a set of moulds I would be cutting down any potential market.

I've already had an enquiry to buy a shell from a concern that makes other fiberglass cars, so do I sell one to them, knowing they might splash their own set of moulds off the parts?

With half a mind to that, my body does have some distinguishing features that although I did them that way because I preferred the way they looked, I also liked the idea that I would be able to recognize one of “my” shells from a mile off. Two obvious ones are that the radiator outlet duct in the nose is a blend of styles between the coupe and spyder, and I have done the centre "window” in the rear a little different to an original.

Cheers

just make sure you get it in writing, if they do pull moulds off it that you're due a royalty, or any work derrived from the shell you sell them, you also retain ownership of.


Fred W B - 20/7/10 at 03:15 PM

Small update, but not much progress to report, have been otherwise occupied quite a bit over the last few weeks.

I attach some pictures of the left door mold buttoned up with all the return flanges (including hinge recess) and edges radiused.

I then had a bit of a set back, when I went to make the first part I flat lost my Mojo. I had spent hours getting the return flanges and plastacine radiuses to the edges sorted and matt cut for the first door part. I applied the gell coat and then rushed starting the lay up (something to do with getting to a social function to watch some soccer match). Didn't let the gell coat go off enough, it started to move around under the first layers of matt so no gell coat on some edges was the result.

So scrapped that attempt and pulled it all out once the surface tissue and first matt layer had gone off. Chalk it up to experience, and at least I proved that my edge radius prep worked well. I then found that my clumsy effort had left a slight texture on some areas of the the mold, so I have had to refinish the mould by sanding with 1200, and then bring the finish back with rubbing compound. Now I have to rewax, reradius and make a start on another attempt on the door.

Cheers

Neville Jones - 20/7/10 at 04:45 PM

You can't hope to short cut the system Fred, and get away with it.

You need to make proper patterns and moulds for the door inners. The melamine surfaced chipboard is ok for one offs, but not for the high quality stuff you're doing.

Just my 2p worth.

Cheers,
Nev.


Fred W B - 20/7/10 at 07:25 PM

Hi Guys

Thanks for responses, and kind compliments.

Nev - To to be honest, I am not sure how well the hinge point surfaces etc I have assumed (from pictures) will work. I hope to get the doors working in the scuttle openings to sort this once that outer mold is made and I can develop the inner detail required in the scuttle. So these inner return provisions are probably really protoypes at this stage.

Although the originals had what looks to be a double sided molding to make the doors, I am currently planning to finish the open piece of my door inners with an ally panel.

Cheers

Fred W B

Fred W B - 25/7/10 at 06:01 PM

Thanks Russ

I have had a question about the tools I used to make the plastacine radiuses.

Taking advice, I made my own not so professional tools, by welding balls (from ball bearings) to a bar.

The smaller tools in the pic are made from stainless steel welding rods with the ends rounded by a power file applied while the rod was rotated in a drill chuck.

Fred W B - 18/9/10 at 05:00 PM

Behold, a door!

Finally finished making up the first real part. I left it in the mold for two weeks. The lay-up I used is:

Gel coat (I first stripe coated all the corners/edges, then two more applications).
1 layer 300 gram CSM.
2 layers 600 gram CSM.
This gave me a final thickness of between 3 and 3.5 mm.

I added extra thickness on the edges, and in the forward part of the door and hinge recess.

The final part weighs 5.5 KG.

The pics are as the part came out the mould, with just the edges cleaned up a bit.

My skills with applying the gel coat and laying up are improving, but still some way to go. I have to keep telling myself "Don't Panic" as I try to get it all done neatly before the resin goes off.

PS - when you come to more complex bits that will take longer, have you thought of UV activated resin, it means you can take your time to get everything right, then open the garage door / wheel the thing outside, and it goes off.... makes things much easier!

Fred W B - 20/9/10 at 07:54 PM

Thanks for all the encouraging replies guys

quote:

Are you working to a target weight for the finished car?



Dave - the original cars weighed about 725 kg. That is with an ally mono chassis, but a larger heaver engine than the RV8 I am using. I am hoping that I might end up at say 850 kg or less?

I am weighing the parts as am trying to get a handle on the optimum amount of resin to mix for each layup. I can now calculate I am getting a resin to matt mix ratio of about 2.3.

As an example, to put two layers of 600 matt on 1 square meter, which the door + flanges is, I prepare 5 cut open plastic milk 2 L containers, the contents will be resin:
800 gram
800 gram
800 gram
500 gram
to give me a bit of excess,
plus another 300 gram standing by, in case!

Then I make up the first mix and start, adding hardener to the second mix only when the first one is used up, and so on.

I use a 10 cc syringe to measure out the hardener, works well. The resin is weighed on a cling wrap covered digital kitchen scale ( did you know cut open plastic milk 2 L containers weight 45 grams?)

I use a roller thoroughly between each layer.

I just did this layup tonight on the next door mold, and it took me two hours start to finish, just the actual layup, not including the prep and cleanup. That includes 4 layers on all the flanges.

quote:

Are you planning on painting the car,



Chris - Yes, eventually, but I can see myself running it for in the gel coat finish for quite a while as I debug it (and save up for the red paint.....)

quote:

when you come to more complex bits



In fact, considering all the returns and recesses on the door, seems I chose the most complex bits to start with! - It can only get easier?

suparuss - 21/9/10 at 06:47 PM

That looks stunning that does! i bet that deep recess was a right PITA to lay up!

Im wondering why you are not using woven cloth though? it gives much higher strength to weight than chopped strand.

ive found if i slightly over wet 300gram chopped strand and then overlay this with twill weave cloth it will soak up all the excess resin giving about as good a result as possible with hand layup. if you do a single 300 gram csm onto the gelcoat as usual to make sure you dont get any airpockets against the gel, and then on the next layup do a 300gram csm/ twillweave cloth combo, and then the same again it should come out much stronger than what you have with a bit of weight saving.


Fred W B - 21/9/10 at 07:26 PM

Thanks Russ, I found the worst bit was the long top and bottom returns, as it was difficult to see in around the corners.

As for different materails, I went this way to keep it simple and cheap for a first attempt, but as you say maybe I should have been a bit more ambitious.

Is woven cloth more difficult to lay up?

Cheers

Fred W B

[Edited on 21/9/10 by Fred W B]


suparuss - 21/9/10 at 08:38 PM

it can be a bit difficult sometimes but wets out really easy. main concern is that it wont conform as easily as csm and you need to be carefull not to fold it over, and anywhere this needs to happen you need to cut it and let it over lap other wise the fold may lift up during curing and forn an air pocket.
other problem is getting long strands tangled up in your roller!

worth the extra effort thoguh by a long way. but i agree if you havent done much fibreglassing it is best to keep it simple to start with.


Fred W B - 1/11/10 at 07:31 PM

Now almost ready to start laying up the "scuttle" section mold. The parting fences are installed (with 3mm hardboard spacers against the door molds to create the panel gaps) and the surface waxed. Just need to plastacine the remaining small edge gaps and finish cutting all the matt pieces and I can then get on with it.

I decided to do this mold in two parts, hence the locating "bumps" at the centre split line. These were made by casting resin around bolts stood upright in the sections of a plastic tray from a box of chocolates, and then finishing them smooth.

What are your plans for lights?


Fred W B - 18/1/11 at 07:08 PM

Plan for lights..

Rear
Use generic 1960's landrover style lucas assemblies, as on the original T70's. I have the actual part number somewhere.

Front
I haven't yet got up the nerve to mark out the cutouts in the nose , so I plan to make the nose mold without them, make the nose, assemble the car and then position the lights in the real nose, using mounting rings to mount 7" lenses.

Once the holes are cut in the nose, put it back into the mold and scribe witness marks of the cutouts in the mold that will then appear on future parts.

Then finish up the internal surfaces of the light recesses, make moulds of the recesses, to then make parts to eventually bond to the nose.

Meantime, save the front corners of the plug, and send them to a friend who does vacuum forming professionally to use them as the basis to make vacuum forming molds for the light covers.

Whew!

Thanks for the info. sounds like a good way of getting everything to look right.


Fred W B - 1/4/11 at 04:53 AM

It's been a while. I've been battling on with the outside sections of the front nose mold.

Hassles included:

I took a chance with some old tooling gel coat, and had to scrap two weeks work when it became apparent the stuff would not harden properly.
Finding a local supplier who would sell less than 20kg of tooling gell took a while.
Removing the parting fences was problematic.
I managed to put some dings in the pattern.
Turns out my parting fence placing is less than optimal in some areas.

to the extent that I have finally had enough of this, so I've given up. This has taken far too much time and money to be sensible and I don't have the strength to carry on.

I have not yet decided if I am going to sell all the running gear bits and pieces I have collected/made or put them into something else. I'll let you know in due course. Must just get over scrapping and disposing of the pattern first.

Thanks all for all the support in the past.

Cheers

Oh no - for a moment there you totally shocked me

I do hope this isn't true


Mr Whippy - 1/4/11 at 08:16 AM

I think you need a break, you may have just exhausted yourself with the sheer scale of this project.

From what I have seen you are very very skilled and I have no doubt that with some more cunning you can get over these hurdles. Your only human mind and pace yourself, if this project takes 5 more years so what?! I have spent 6 on just one little car and I'm still enjoying working on it but do need to leave it sometimes and come back refreshed.

If you've really had all you can take just now, wrap it up and put it away for a while, don't do anything rash and wait till you feel like working on it again. I find going to car shows always helps and gives me bursts of enthusiasm.

You owe it to yourself for all the hard dedicated work you have put in so far, you will finish it and you'll be all the more proud of what you have achieved knowing what a struggle it has been.


Fred W B - 1/4/11 at 06:56 PM

Thanks for the responses and enthusiastic support. As suspected, the last part of my post was a leg pull, I am still very determined to finish this damn thing.

Cheers

Fred W B


Fred W B - 3/4/11 at 05:35 PM

Current status.



Here you can see the difficult acute angle I've given myself at the front edges of the parting detail, and 2 small scars I've put into pattern. Wil just plastacine these up and poiish the marks out the mold. They might even be in the headlight cutout.




Ive built some benches to stand on to ease access to the upper surface, and down into the nose duct.



Trying to decide that I CAN lay this up in one hit.




Cheers

Ivan - 3/4/11 at 06:45 PM

To my untrained eye looking at it in 2D it looks OK for one part moulding - would think that the air vent shape is the critical factor. But if something about it is causing you uncertainty go with your gut.


Steve Hignett - 28/4/11 at 09:34 AM

Apart from it being a large area, I also think it looks perfectly fine for a one piece centre. The only worry from my point of view would be the time it takes Vesus the resin pot-life you use.

With the stuff we have at work, that would take a LOT of prep work and two guys just to make sure we got it down before it exothermed as it goes off so darn quick

Still looking great Fred, top notch work...

I can't say that I would have done the front wing flange at that angle, I would have come off the body at an angle to give a slanted plane to work both moulds into, but some of the world superbike stuff that we mould is tighter than that, so it shouldn't be too big a deal!!!


Fred W B - 28/4/11 at 05:18 PM

Thanks Ivan and Steve for your comments, and opportune Steve as I have just finished the first layer (tissue + 300 gram mat) of the centre piece.

I had been putting it off, waxing, rewaxing, making matt templates, cutting the various bits of mat (including the multiple corner fillets) etc etc, and doubting If I could do it okay single handed. I laid out all the matt pieces in order, and even did a "dress rehearsal" of laying the bits in. At this stage I cut the surface matt to butt into the flange corners, with separate pieces to fit on the flanges, and fillet corner pieces then laid into the corner joints. Also did some detail pieces around/in the location bumps. The surface only was 9 separate pieces of matt.

I finally screwed up my courage, started at 9.00 Saturday morning and by 2.30 it was done, with the exception of the corner fillets down into the nose duct, which I finished yesterday, after sanding the applicable areas. The complete area with flanges is 3.6 m2. I put the 1.8 kg of gell on in three stages (corners/edges + coat 1 + coat 2) and made up 700 gram batches of resin which I catalysed as I went along, working nonstop.

Thier are a few very small areas where I have chased back into small air bubbles and repaired, deep in the front recess particularly was a pain, but I thought I did pretty well overall.

Now to finish sanding the surface and cut the 600 matt for the next layers.

Re the front wing flange, I consider that a lesson learned

Cheers

Great to see the progress.

are you gong to bond any wood or a core to the center section of the mold?


clairetoo - 29/4/11 at 07:56 PM

Frad - I have been following this thread for a long time , and I have to say I am relieved to see you are continuing your work - when I read you were ready to chuck it all in a skip and give up I was gutted
I have made moldings of at least as large an area , but with a lot less complex detail - I just mix up 4 or 5 KG's of resin , with a bit less than the recommended 1% catalyst , and go for it


Mr Whippy - 29/4/11 at 08:22 PM

keep going

This is such a learning experience for everyone following this build just can’t wait to see the finished moulding and it’s soooo amazingly shiny!


Ivan - 30/4/11 at 06:52 AM

I continue to be amazed but there is a downside - I always had a dream of making a Porsche 904 or renault Alpine from scratch as Fred has done here and now realise that there is no way I would ever have the patience and determination to achieve the sort of results he has.

You might want to check the date of the 'giving up' post


Fred W B - 1/5/11 at 03:00 PM

Thanks for the responses Folks.

Ceeb - I do plan to bond some wood reforcing ribs on once the mold thickness is built up.

Claire - I use 0.75 percent catalyst. As our autumn has started our ambient temps have started to drop (to under 25 deg C)which also helps.

Chris


Fred W B - 26/6/11 at 03:59 PM

And today I rounded up some mates to help lift off the bigger bits. The scuttle mould came off easily



but the nose upper section put up more of a fight. Judicious use of levers, wedges, ratchet straps, roof rafters, hammers and mallets was necessary to "crack" it loose. It's a damn big heavy piece but it is off now.

Amazingly all the surface of the pattern stayed behind.

Steve Hignett - 4/7/11 at 09:33 PM

Hi Fred,

Your post above (on 29th I think), you make a comment about how difficult it was to remove off the pattern, and I'm not surprised!

Did you ever consider making the rad-outlet dip in the bonnet as a seperate part of the bonnet mould? A flange round the edge and dropped in and then obv through from above?

Obviously, you're not going to do it now, and I don't know whether it would be better or impossible from the Pics, but I just wondered whether it had crossed your mind or not?

Rgards,

Steve



And keep up the fabulous progress!!!


Fred W B - 5/7/11 at 08:12 AM

Hi Steve

I think I can see on the mold some small areas in the depth of the nose duct where it "hung up" . Possibly this is because that is where it was physically much more difficult to apply and rub out the wax, so maybe my preparation was not as through in that area.

I did consider (in fact agonized over) making the duct section a separate section, and I suspect I will still regret not doing so. This as the return section under the nose goes back a long way, such that now I will probably have to work though a gap between the front side of the duct return and the rear edge of the under nose piece when laying up some of the detail inside the front of the nose. I think I will have to make my under nose return shorter than on other T70's to make this possible. This is the section of the pattern I am working on now - see the last pic above. Thanks to another forum member I know that the GD goes back under the nose (from the bottom of the front opening in the centre) 385 mm. The rough surface you see on the pattern now is a bit longer than that.

So far I have tried to do all my moulding work "in one", but I have seen it stated that large mouldings can be done in sections, and because of the above problem might it be more practical to layup the part surface in the majority of each separate mould piece before assembling the mould pieces together and completing the nose?

How does one do that? Is it a case of stopping the gel coat application say 30 mm short of the join lines, and then tapering out the part layout just short of the edge of the gel. Then bolting the mould pieces together, applying gel over the joint sections, and then completing the layup? Would the result be satisfactory, or must I make every effort to do the nose layup 'in one"? I'm starting to think that might be very difficult.

As you can see I am still learning this stuff as I go along.

Cheers

Fred W B


ceebmoj - 5/7/11 at 08:25 AM

Hi,

I cant comment from experience of having done it my self. However if you look on you tube there are a large number of videos by a guy called "how to build a b1 bomber" and he sprays the gel cote in to the mold sections then lays up the mold sections timing the edges once they have gone very tacky and then glues the sections together however this seams to lead to some very long days while he does all the layup.


suparuss - 6/7/11 at 12:54 PM

Hi Fred, looks like you are making lots of progress! looking very nice indeed. ive just finished and mounted the main body shell on my car which although ive done it in 2 halves it was still 2 fairly large but really complicated pieces to lay up so really needed to be laid up in sections.
i put the gelcoat on the whole thing and then put the first layer of glass over that on the whole thing. once you are at this stage you can sart to lay up in sections as your resin will be air inhibited meaning that you can leave the section you dont want to do yet and it wont fully cure until you do lay more glass over it. just needs a quick sand and then prime with some acetone as usual.
id only lay up thin sections at a time so that you are gradually building up the thickness over the whole part, if you go thick in one area before moving to the next you may get un-predictable warpage.

Cheers,
Russ.


Fred W B - 6/7/11 at 06:23 PM

Please keep us updated and again, absolutely amazing.


Fred W B - 11/12/11 at 06:23 PM

Hi Guys, Thanks for the encouragement.

So one night this week I invited some mates over to help lift the nose pattern, and we demoulded the nose again. Then moved the nose mould sections to storage. I assembled the complete nose mould and finally I can see inside it.

The dark specs you see in the detail pics are bit of plastacine

Fred W B - 11/12/11 at 06:32 PM

This weekend I cut the front off the nose, to keep to one side to use later to sort the headlight recess/covers detail, and scrapped the rest of the nose pattern.

I have retained the scuttle section of the pattern as I still have to do something about the returns and internal details in the scuttle.

Now I can get on with the tail mould. The door moulds are still on the pattern so I can mark the forward edges of the tail section.

Cheers

Fred W B - 15/12/11 at 05:28 PM

Thanks for the kind responses all.

Re scrapping the buck sections, It's what I have to do to move on, so I just got on with it. I did double double check where I was cutting before I fired up the angle grinders and chain saw though!

It is great to have some more room in the garage now, for years I have been moving around in the narrow alley around the pattern.

Currently making progress on cutting the rear sections of the doors out of the pattern. This so I can then make the forward facing surfaces of the rear body section that are in the door gap. You can see the 3 mm gap that will become the door gap in the lower pictures

Cheers

Hay Mango, will be pleased to meet you, give us a shout when your planning is confirmed.

Not posted for a while, had some things going on that kept me out of the garage for a while.

I have now finished the first 2 sections of what will be a 6 piece tail mould, these being the outer face sections of the forward facing areas of the tail, including the inserts that make it possible to form the inner surfaces of the "hip ducts".

After making the insert moulds, these were closed off, and another mould made over them over the full forward facing surfaces. The surface down towards the belt line may be bigger than necessary, I can cut the parts back if needed later. I incorporated a step out block to give a register between the insert and face moulds. The insert section moulds are secured to the face moulds with screws.

The idea is that the full tail part is first made with the insert section removed from the face mould. The open area of the duct is then cut out, up to the join line. The insert mould is than screwed to the removed face mould and a moulding made separately of the insert. The insert part is then trimmed to the join line, the insert part put back onto the mould and the face mould bolted back into the full part mould, so that it positions the insert part in the correct place. The insert part is then bonded into the tail part.

Hope that makes sense, the pictures may help explain what I am trying to do. The insert and face moulds happen to be made with different colour green tooling gel, which make the join line easy to see

Cheers

On your bigger panel are you sticking some airline PCL connections to use when releasing the parts from the moulds.
I was watching a video making a body shell for the new shelby cobra and they had them installed in the mould.
When the release came it was blow air in and pop out it came.

Will defo make a trip to PE on the garden route in a hertz rental


Fred W B - 23/4/12 at 04:34 PM

Hi Mango

It's not the bigger panels I'm worried about, as my multipart split molds should make it easy to demould. I did use air to help release the insert "bucket" moulds from the pattern, you can see two holes in the back face of one in a picture above. I didn't bother to add connections, I just held the air nozzle firmly into the suitably sized hole and it released well enough.

Thanks for the thought.

So lately progress has been slow albeit steady.

The entire tail section has been waxed, and all the parting fences made and installed.



Fred W B - 8/7/12 at 07:16 PM

Working now on the next section of the tail mould, all matt templates have been made, matt cut, and today at 10.30 I started with tooling gel application, then once it had gone off I applied tissue, then one layer of 300 gram mat on the surface and flanges, + fillets in the corners, then a layer of 600 and 2 layers of 600 on all the flanges.

For the parts i'm planning on using ordinary Poly resin and glass matt (tissue, 1 x 300 + 2 x 600). Might add some foam between skins at some points, not decided yet

hi there,

Have you made any progress?


HowardB - 14/12/12 at 12:01 PM

I am seriously thinking that we should run trips to see Fred's work on this,... I am really looking forward to seeing the pictures.


smart51 - 14/12/12 at 12:20 PM

Yeah, very much looking forward to the next installment. Have you done the rear deck yet Fred?


Fred W B - 15/12/12 at 04:09 PM

Thanks for the interest guys. Over the last few weeks it has been difficult to find much garage time but I am now just about finished with the top of the tail mould. In fact today I finished making up the wood bracing, and should get it bonded on tomorrow.

A few pictures of the braces in position but not yet bonded on. You can see that I am experimenting with putting a strip of closed cell foam between the braces and the surface of the mould. This is to hopefully prevent "print through" from the braces on the large flat expanse of the tail top surface

Cheers

Fred W B





Fred W B - 15/12/12 at 04:20 PM

This was a big area, over 3 M2, and each session of two layers of mat needed about 10 kg of Resin.



ceebmoj - 15/12/12 at 04:37 PM

Looks great as all ways. Is this the last pice of the mould? If so what is next?


smart51 - 15/12/12 at 04:40 PM

I'd never considered print through from wooden braces. I like attention to detail like this.


sylva_phoenix - 20/12/12 at 08:50 PM

That's a fantastic project. I planned to do something similar, but Time and money won't allow it....


Fred W B - 21/12/12 at 05:02 PM

Thanks for the comments guys

Fred W B - 24/12/12 at 02:11 PM

And now the tail mold bracing is bonded on, all the fastening bolts through the flanges are fitted and finally I can say the body molds are finished!! Only took 1 week short of 6 years since starting to build the pattern.

Have a good Christmas and New Year All!

Cheers

Awesome work Fed!

I hope it doesn't take you another 6 years to complete a car! I can't wait that long to see it!!!!


TimC - 24/12/12 at 02:49 PM

Merry Christmas Fred. Absolutely awesome work.


ceebmoj - 24/12/12 at 02:49 PM

congratulations on reaching this mile stone. I look forward to seeing bits of body work.


GonzoRacer - 24/12/12 at 04:37 PM

Your work continually amazes me. Great designs, great attention to detail, all around world-class workmanship. I'm looking forward to seeing more.

Merry Christmas to you and yours, and good wishes for 2013.

chrsgrain - 27/12/12 at 06:34 PM

Awesome, awesome, awesome.....

Bring on the body parts! Decided on a colour yet?

Chris


Fred W B - 28/12/12 at 12:04 PM

Thanks Chris

As for the colour, I will initially get the car running and debugged in the white gell coat, but eventually the plan is to paint it a deep blood red and silver, just like the single seater below (the current favourite is Honda's "Milano Red" as seen on a Jazz or other model near you).

Sills will be the silver below the beltline as well, running into a gulf GT40 style "moustach". Stripe will be a broad centre stripe with two smaller stripes each side, like the second picture below, but with wider side stripes, more like the third pic, but here maybe too wide. Also here the red is too maroon for my taste.

Maybe now you are sorry you asked, but I have been thinking about this a lot......

Cheers

Fred W B

ceebmoj - 19/3/13 at 07:13 PM

hi, Hows the project going?


Fred W B - 20/3/13 at 08:17 PM

Hi Ceeb, Thanks for the interest

The short answer is that I now have both doors made



and the scuttle is laid up, I just want to leave it in the mold a few more days before I pull it.

As I wanted to have returns on most of the scuttle edges making the part turned out to be a bit of a nightmare.







In the below two pictures the camera is held where it is not possible to get your head, so some of the detail on the return flanges had to be laid up blind (and some upside down!).





Because of this complexity I decided to lay-up the scuttle in three sections. The left hand and right hand pieces were done first. The above and below picture is of the side I did first, I got the flanges neater on the next one.



These were then connected by doing the centre section later.



The layers in the lay-up in the join area are tapered to try keep the thickness even across the joint. I did make a bit of a mess of the gell side of the joint, but I think it can be saved by sanding and it's experience that will stand me in good stead on the larger parts still to be made. The picture below is of one side of this joint.



And just tonight I've added internal flanges to support the body shape where the perimeter flange has to be omitted to permit the door to open.



So I feel that some good progress has been made as 3 body sections are now finished. Just the small detail that the nose and tail which are still to be done each have a larger area than all 3 parts made so far.

Cheers

Fred W B

smart51 - 20/3/13 at 10:28 PM

Looking good Fred. I admire your patience. I'd be itching to pull it from the mould.


Fred W B - 23/3/13 at 11:42 AM

Thanks for the kind responses Guys.

The scuttle is now out of the mold, and I could not resist mocking it up with the doors. Does it look like part of a car yet?

Cheers

Fred W B











ceebmoj - 23/3/13 at 12:53 PM

wow.

I cant weight to see the rest. I think you may have been asked before, but do you intend to sell bits when you are done?


Fred W B - 24/3/13 at 07:24 AM

Hi Ceeb

Certainly if their is interest I will look at selling bits. Think that I might have to investigate getting a commercial concern to make parts in my moulds though as it takes me so long.

Cheers

Fred W B


Fred W B - 24/3/13 at 07:34 AM

All this time the mock up chassis has been supporting the cutting table. I pulled the top off, cleaned up the huge accumulation of sanding dust and glass fibres and tried the scuttle on the mock up chassis. It doesn't fit badly considering that when I made the mock up I did not know what body I might use.

And yes I tried sitting it and just sat there contemplating the progress for a while. I didn't make motor noises though

Cheers

Fred W B

Sorry Fred, but thats a crime... you must go back into the garage right now and make some brum brummm noises while sitting in the driver seat

parts look fantastic, really looking forward to seeing the complete body


chrsgrain - 27/3/13 at 08:51 PM

Wow - its always difficult to tell in photos, but those parts look SMOOTH... lovely work, nice panel gaps... awesome.

I thought I remembered that you've got the chassis all done and dusted, but that last post suggested that you've still got to make it??

Chris


adithorp - 27/3/13 at 09:09 PM

Hasn't anybody ever told you kit cars can't have a finish like that. Panel gaps are supposed to be huge and uneven.

I'm just glad it's taking you so long, Fred... 'Cos when it's done everyone else's car's will look crap by comparison.


Fred W B - 30/3/13 at 02:27 PM

Thanks for the complimentary comments guys

Andy - As for making engine sounds while sat in the chassis, if I did make some it would be how a V8 engine sound was depicted in writing in those wonderful "CARtoons" 70's comics, like this ..... Duga Duga Duga Duga.... .If you say it right it does sound like a V8 with open exhausts at idle.

I still have some of the comics

Chris - The chassis so far is a roughly built mock up protoype that I put together to sort the ergonomics and the layout of the running gear. I welded it almost fully and tested the torsional stiffness. I stopped working on it as I needed to sort out the overall width over the wheels and for that I need the body confirmed. The idea now is to finish the body, and then hang it over this mock up chassis to finalize things like where the radiator mounts, suspension etc. Once that is done I will then build a real "final" chassis. Some of the frame parts or subsections used in this exercise could become part of the final chassis.

Adithorp - I'm sure it wont be that easy to get the panel gaps right once I have to hang the panels and actually make them open and close.

Cheers

Fred W B - 30/3/13 at 02:36 PM

In further news, now that the scuttle is out of the way, a friend helped me pull the tail mold off what is left of the pattern.

We bolted it tougher roughly to get an idea of the scale of the next step. It's a big part, the surface area is over 6 m2. Now to get on with preparing this. Some more return fences to make, then more polishing, matt cutting etc etc.





My gell coat application does not look so good when the rear panel is backlit in the open door like that







Feels like I've come a long way since I bought the model to copy!

Made a bit more progress, scrapped out the rest of the pattern. I saved the rearmost portion of the tail and hung it on the wall.






Fred W B - 5/5/13 at 06:41 PM

Finished the returns on the edges of the tail, and made the former for the hole above the engine.






I made this a separate piece so that I can change the size of hole, or omit it altogether on future parts

Cheers

Thanks Smart, considering that I have not yet even polished the surface

I will run the usual plastacine fillet along the corner, to give me a 4 mm radius. The former actually fits tightly against the surface, what looks like a gap in the pictures is a thick blue felt tip pen line I drew around the former to mark the position.

Cheers

[Edited on 6/5/13 by Fred W B]


Fred W B - 30/6/13 at 07:25 PM

I've made some progress on the tail section. Because of the size of the part, difficulty of access and as I work mostly on my own I have to make the part in sections.

I laid up the side sections first




I made this tool to help work the matt into the tight corners of the wheel arch lip



Fred W B - 30/6/13 at 07:27 PM

Then I laid up the rear section



Fred W B - 30/6/13 at 07:31 PM

Then the main top surface




I masked the 2 layers of gell edges and staggered the edges of the 3 layers of matt to enable me to blend in the joining sections


Fred W B - 30/6/13 at 07:38 PM

Then I dressed the edges of the part sections and bolted the 6 outer pieces of the mould together. The next step was to glass over the join between the sides and the top section. Again the joining pieces of matt were staggered in width to give an even thickness across the join. The dark marks in the layup are pen marks I use to align the matt pieces



[Edited on 30/6/13 by Fred W B]

Well done, Sir!

smart51 - 30/6/13 at 07:44 PM

Good to see your progress. I can't wait to see the finished result.


Fred W B - 30/6/13 at 07:47 PM

Thanks for the comments guys

This weekend I had to position the mould almost vertically to make it possible to reach all of the top edge of the tail to top section join area.






Fred W B - 30/6/13 at 07:48 PM

and here you see the prepared matt to make that top edge join



That was laid up today. My hamstrings are going to feel it tomorrow!

Fred W B - 17/7/13 at 08:25 PM

Thanks Ceeb

Demoulding won't happen for a while yet, although I have since done the front faces of the clip. I am keen to see the finished part but after all this time I can wait a little longer to make sure it is right and gone off properly.

Currently I'm busy with making the "nostril" inserts.

Cheers

ceebmoj - 17/7/13 at 09:55 PM

Great update. I really look forward to seeing updates to this thread.


AlfaDriver - 21/7/13 at 01:05 PM

Just joined the forum to say...
What a FANTASTIC job you have done there.
I worked with GRP before and we did some big and complex jobs nothing close to yours.
We used to use chipboard, steel frames and body filer for detailing
Can you let us know what materials you used ?
I'm specially interested in the skin over the foam because the experiments I have done with body filer strait into the foam the foam reacted and shrank/melted leaving a horrible surface.
Looking forward to you next update.

Ric


Fred W B - 22/7/13 at 05:32 PM

Hi Ric

Thanks for your interest and compliment

The pattern was made out of wood and polyurethane foam, some shape added with plaster filler. Then the whole thing was skinned over with a good layer of 600 gram chopped strand matt and resin. Upol body filler was then applied over this and finally 3 coats of Durabuild spray filler to get the final finish.

Cheers

Fred W B

Mistron - 22/7/13 at 05:57 PM

I get mine from: http://www.ecfibreglasssupplies.co.uk/p-556-2-polyurethane-foam-sheets-50mm.aspx

You are right though - many people have tried to use pink, blue or yellow rigid foam insulation sheets from builders merchants. Yes it's cheap, but sadly, it's also useless unless you skin it in tinfoil etcto prevent the reactions.


AlfaDriver - 22/7/13 at 08:49 PM

Thanks Fred and Mistron

In the shop I used to work about 98% of the molds/panels we made were made with chipbord/mdf.
The really big stuff like buses rear ends were reinforced with a metal frame after the matting and covered with more mat.
I'm trying to remember the name of the stuff can can't figure it out...
Does any of you know the name of the polyester(?) that is fire retardant ?
We used to use it for places that were subjected to high temperature like the buses rear end and engine covers
All I remember is that is was white/milky type of resin.
Going to do some more investigation for my project.

Ric


Mistron - 22/7/13 at 08:54 PM

Here's how I combined the foam and MDF on an old project, but sadly never got as far as Fred, of whom I am in awe!


13-05-07_2145 by alastairbrownuk, on Flickr


Fred W B - 31/7/13 at 08:16 PM

Thanks for the compliment Mistron

Made some more progress, and apologies if I'm going into lengthy detail on this, but I've now got the nostril inserts bonded in.

Parts looked like this once I pulled them off the moulds. The ridge across the upper face of the bottom part in this view is where the join will be on that surface. On the rest of the perimiter the join will be on the centre of the edge radius.



Fettled them so that they fitted into the holes in the tail. The mould was bolted back together to support the inserts in the correct position.



I tried to get a nice even 1 mm or so gap all round, so that I could hopefully get gel right through the joint to the front face.



I made up a gel mix with some resin added and applied this with a long thin brush to the back of the join. Then applied matt and resin over the join where I could, some of the area right of the bottom of the "valley" was difficult to get to so there I just flooded it with resin and dropped a quantity of loose fibres in down the gap and worked them in with the thin brush.

Once that had gone off I dressed it and then applied expanding foam in the gap.





That was also dressed and then glassed over to finally secure the insert.



Must admit to being very happy with the result, it looks like just enough gel seeped though the join around most of the perimeter to make it easy to flat it back to a good surface. The blue marks in this picture are from the marker pen ink that was on the edge of the part, they are not chips in the gell coat.



Now just want to trim some edges and I can then get the tail out the mould

Cheers

Fred W B

I love catching up with this thread Fred.

Top work as always!


Fred W B - 9/8/13 at 05:54 PM

Thanks for the comments guys.

I gave myself quite a challenge in making this part as it is a 4 sided section that had to have the 3 layers of mat fed in and laid up through a slot in one side of the part. It was touch and go far a while as the loose edges of the layup were always in the way but I finally managed to get them to lay down and it turned out okay.

This had to be a seperate piece to allow the tail to open with fixed backstays fitted to the rollbar.







[Edited on 9/8/13 by Fred W B]


Fred W B - 9/8/13 at 05:57 PM

and I reckon the effort was worth it when I see the final result.




Fred W B - 9/8/13 at 06:06 PM

Positioned the tail at ride height and tried a wheel for fit in the wheelarch






Fred W B - 9/8/13 at 06:09 PM

Looks like it deserves something wider than the 245 section tyre shown here

The edge of the opening in the tail is not yet finally trimmed.

Cheers

Fred W B


Fred W B - 25/9/13 at 05:53 PM

Small update!

Turned out I had some imperfections on some areas of the nose mould (particularly where I tried to get away without using the durabuild surfacing primer on the buck under the nose) and I got a bit sucked into improving the finish on most of the mould by sanding and compounding. That took some time, as did the making of return fences and the usual tedious waxing but I'm now finally making progress with the parts sections of the nose.

Cheers

Fred W B







[Edited on 25/9/13 by Fred W B]


ceebmoj - 28/9/13 at 11:35 PM

Fred W B - 29/9/13 at 06:52 AM

Thanks Ceeb. This picture should help you identify the part, its a section of the nose, although the other side to that shown below

Cheers

Fred W B




[Edited on 29/9/13 by Fred W B]


Fred W B - 10/11/13 at 03:19 PM

So I completed the nose, stitching the 4 sections together using the same technique I described for the tail








Fred W B - 10/11/13 at 03:22 PM

The nose completed the set of body panels, so finally I can say the body is finished! That is if your don't count the headlight arrangements and the wheel arch inner panels.

These pictures are with the panels supported on blocks, and with the wheels just placed in the wheel arches.

Plan now is to take some time to spring clean the workshop, and then start to get to grip with the suspension and chassis.

Cheers

Fred W B - 11/11/13 at 05:42 PM

Thanks for the very kind comments guys

As for the chassis, I am pretty motivated to get on with it, I prefer the mechanical stuff to bodywork.

The chassis I've built so far is a rough mock up protoype that I put together to sort the ergonomics and the layout of the running gear. Its a tube frame with ally skinning to the centre section. I welded it almost fully and tested the torsional stiffness. I stopped working on it as I needed to sort out the overall width over the wheels and for that I needed the body confirmed. The idea now is to hang the body over this mock up chassis to finalize things like where the radiator mounts, suspension etc. Once that is done I will then build a real "final" chassis. Some of the frame parts or subsections used in the mock up exercise could become part of the final chassis.

At this stage I am not intending to attempt a replica pressed style tub chassis, maybe that will be a longer term project.

Reckon I should start a new thread to document progress on the chassis, this one has gone on for long enough now

Cheers

Hi Ivan

They are 15x7 and 15 x 8 "Superlights", with centres painted "charcoal". I imported them but now they can be supplied by a chap in Cape Town, I have his details at work. I want to eventually fit 8"s and 10"s

Fred W B - 2/2/14 at 02:36 PM

Hi

I said I would start a new thread to documument the suspension / chassis build, but I haven't got much progress to report, at the moment I'm still busy with tiding the garage and a few other non project things.

We've also recently had a death in the family which threw up some issues that needed my attention and that took some time.

What I have done is got the body positioned over the mock up chassis, and test fitted the motor and transaxle. The build table is back on castors so I can move it around, and under the cable hoist when I need to lift the motor etc.





I'll make the cut-out at the distributor a bit bigger when the final build is done.





I'm pleased I will only need a small rebate in the tail to clear the rear of the transaxle, and that the cut-out will not interrupt the horizontal line across the lower part of the tail when seen from the rear. The position of this plain was a guess when I made the pattern but it seems it will work out well. I'll glass in a recessed closing panel over an enlarged cut-out when the final build is done.






Cheers

Fred W B
