A New Project, GT6 aluminium body
John Bonnett - 22/1/13 at 05:55 PM

I hope this fits in to the Forum although strictly speaking it is not a Special; only a special body.

I have recently restored a MK3 GT6 and I really love the shape and lines of the bodywork. I originally bought the GT6 to use as a pattern for my new project; an aluminium replica body but it was so good I had no alternative but to put it back on the road for the first time since 1989 so losing my pattern but in return, deriving a great deal of pleasure both in the restoration and the 7000 miles of driving since April last year including two continental holidays.

As luck would have it, I located a MK3 bodyshell locally which has proved ideal for my purpose. I also have a tax exempt MK4 Spitfire onto which I am going to fit the new body.

I'm going to make a tubular steel frame to support the bodywork but for the last few days just to get back into the swing of metal shaping, I have formed some panels for the roof.






So although I have nothing in place as yet to support the roof, I'm going to finish it and then build the frame to suit.

John

Can't wait to see more of this! Epic!


Mr Whippy - 22/1/13 at 06:48 PM

Good work but will an aluminium body be strong enough in a crash, the steel ones arnt all that strong in the first place, the spitfire chassis is very much inside the parameter of the bodywork so you can't rely on that. My brother in law has a red spitfire which I use quite often in the summer, it's a fun car if a bit low and the bonnet shakes a lot


mark chandler - 22/1/13 at 06:52 PM

Triumph made some lovely shaped cars, you have a hefty challenge there.

Which version you after, I prefer the mkII myself.

One car that I would really like is the TR4a, mint ones look fantastic


John Bonnett - 22/1/13 at 07:58 PM

Tegwin, yes I know it's an ambitious project but I'm hoping I have enough hours left not only to finish it but to enjoy driving it.

Whippy What's with these negative thoughts? If we worried about the consequences of crashing we'd never drive anything other than a Volvo

Mark I'm afraid it's going to be based on a MK3 GT6. It's very subjective I know, but perhaps unlike the majority I prefer the shape to the earlier roundtails.

So, a little bit more detail which I hope will put my friend Mr Whippy's mind at rest. I'm using the steel floorpan from a MK4 Spitfire and onto that I'll fabricate a tubular steel frame that will provide a safe and rigid support for the aluminium bodywork. The advantage of using the steel floorpan is that it provides the strength of the sills, needed by the chassis and of course the mountings for the standard seats. The bonnet too will have a supporting frame from which it will derive rigidity..

It is my intention to arrange things so that the standard bonnet and doors will fit my frame so if I sense that time is running out I can take a couple of shortcuts to get the car on the road.

Thank you for your interest and your replies. I'll keep you up to date with more pictures as the project unfolds.

A really excellent project. Where did you pick up the skills to hand make body panels, it's an incredible and a rare skill ?

Thank you but I'm self-taught and very much an amateur who likes a challenge.


mark chandler - 22/1/13 at 10:24 PM

MkII does have a nice round bottom, they spoilt them with the mkIV

Good choice then, very hard to make matching sides, you must have a nice big English wheel then.


Uphill Racer - 23/1/13 at 12:55 AM

In the dim and distant past I had a Spitfire 4, the first model they made and came with a works steel hard top.
When it came to fitting it after summer........, I had to put my back against the windscreen and feet on the rear bulkhead to stretch the living area to fit it....................The good old days..................

Now then what engine and running gear?
There's an opportunity to sort the rear end out and put a bit more power under the vast bonnet

Ah, now there's the problem. I'm doing my best to avoid IVA and if I modify the chassis by altering suspension points or don't qualify for the mandatory eight points by not having retained sufficient mechanical components, it would have to go through the test.

If there were no constraints, I'd fit a Zetec/Type 9 combination and as you suggest do something with the rear end. But, the body is quite a meaty challenge so I'll get that under the belt first and see how it goes; literally.


rdodger - 25/1/13 at 09:00 PM

Couldn't you change the engine on the V5 now? Engine swops happen all the time!


adithorp - 25/1/13 at 10:08 PM

Good to have you back, John. Whatever the project your skills are always worth looking at.

Like Roger said, change the v5 first. But I think it should at least be another 6pot... Otherwise it'd be just a GT4. Have you seen Claire's MX5 THREAD ?

Would the chassis need modding if the transverse leaf spring was replaced with a wish bone mounting bolted to the diff instead?Might take a bit of thinking out to work but it could be done ?
Keep up the good work John

John Bonnett - 26/1/13 at 06:27 PM

Adi and Rusty, very good to hear from you and thank you for your good wishes. We just need 907 to come and join the party

Yes Claire's workmanship and skill is absolutely awesome and all apparently accomplished with consummate ease!

You are both absolutely right in what you say both about the engine change and ways of improving the rear suspension. But for the moment at least all my attention is totally focussed on the bodywork. One of the many problems I have as someone with very limited skills is trying to reproduce crisp coachlines that have, on the pattern, been pressed in and I am already considering taking a broader approach and rather than an exact replica produce a body that is inspired by.... if you see what I mean. If you go back to pre-war times, panels generally didn't have sharp creases, were more rounded, and easier to reproduce by hand. The decision was made when looking at the side roof section as picture



The line is as sharp as I can make it but not good enough and no matter how well the rest of the body turns out to be, the eye would always be drawn to that coachline. So easiest is to leave it out and continue the curve of the roof down to the gutter. There may well be similar decisions taken with the rear wings and on other parts. We'll see how things progress.

It is really good to be back amongst my friends the Locosters and to be involved in metal shaping once again. It really is addictive!

[Edited on 26/1/13 by rusty nuts]

believe you me, not as easy as it sounds. The leaf spring is possibly (and unwittingly) far cleverer than it seems. Besides, the bottom wishbones on the triumphs (the ones that have them) are short and not ideally positioned.

People have mocked up double wishbones, but I haven't seen one yet that I would remotely consider. Honest. Best I have seen is somebody who has modified the lower wishbone and mountings to achieve zero camber change. But I am unsure if that is beneficial. I suspect the inner wheel wants to be in positive camber (so it leans into the road/track) and the outer wheel negative. So they are sort of parallel.
Hmm, there my ideas run out.


rusty nuts - 26/1/13 at 07:47 PM

ISTR there used to be a leaf spring to decamber the rear suspension, possible from a company called SAH that was supposed to improve the rear suspension?? I've never really looked at the rear suspension with modifying in mind but would have thought that it would be possible to maybe attach a lightweight subframe with suspension attached that would not need to be IVA'd?

Hi John,

There was a time, when at the mere mention of a party my three word answer would have been; "Mine's a double."


Sadly, my answer now is; "Two sugars", although that's not strictly true.
"Two sweeteners" is nearer the mark.


As for crisp lines I would say, if a jobs worth doing it's worth doing well. Better to find a method of sharpening the lines
than making compromises that at the end of the job your "heart of hearts" isn't happy with.

I made 4 rear arches before I was confident enough to make a mirror image one for the other side of my car.
Life is a learning curve, and metal shaping even more so.
I now consider myself in the 40th year of my apprenticeship and still learn something every day.



All the best John,

Paul,

Very good to hear from you and thank you for your wishes and words of wisdom; as always, very much appreciated. You are absolutely right about not settling for a job that you are not 100% happy with. It's like "Marry in haste, repent at leisure!"

I've thought long and hard about about the coachlines and have made the decision simply not to have them. The roof will just curve down in a tighter arc to the point where I'll pull out a return flange as part of the gutter. That particular panel if it did have the coachlines, would need making in two parts and welded together and getting the two coachlines to line up with a weld crossing and to be identical to each other is beyond my meagre skills. In actual fact, I don't think the coachlines add anything to the beauty of the shape and in my opinion a progressive curve will look better.

I've made a start and it all looks very promising. Pictures to follow.

Best wishes Paul

John


John Bonnett - 28/1/13 at 04:24 PM

This is a picture which shows the coachline I'm referring to.
[img][/img]

I don't think it adds anything and in actual fact a progressive curve might be visually more pleasing. So,I formed quite a nice a sub panel omitting the coachline but it was ruined it when I turned the flange for the base of the gutter and no amount of shrinking made it any better. I'm still unable to upload any photographs which is perhaps just as well. So, my next plan is to form the gutter separately and weld it onto the sub panel.

All part of the learning curve


John Bonnett - 11/2/13 at 05:18 PM

I've made some good progress and have now nearly finished wheeling the main roof panel and the two sub panels. Unfortunately, I've been unable to upload any pictures.

They say that a low crown panel is among the most difficult to form and my aching arms and shoulders wouldn't argue with that. But, a great feeling that the roof is done and ready to weld together.

Now, come on. I've been looking through your photo archive and your workmanship is of the highest quality and something to be very proud of.

On my project, I've been beavering away slowly but making progress. The gutter under which the tailgate fits has slowed me down while trying to find a way to make it using my limited skills but I hope I've come up with the answer.

I've just two pieces left to make before the panels that I've made can be welded together to make a complete roof.

I've been able to upload the pictures now so thank you Chris for sorting out that little problem but I've forgotten how to include a fullsize picture in my post.

Ah, now sorted

John Bonnett - 14/3/13 at 09:16 PM

I was hoping to have all the roof panels finished by now and ready for welding but have suffered a bit of a delay.

I'm getting a bit old and senile and the first thing I didn't notice was that I had turned the flange for the gully (N/S tailgate gully) up instead of down and to make matters worse, the lower wheel on the jenny had slipped backwards so that I had two knife edges top and bottom instead of just at the top. Result was a wonderfully crisp fold but a deep score as well. So no chance of reversing the fold and therefore, I had no choice but to bin the panel and start again. The good news is that its replacement completed in a fraction of the time, is actually a truer shape than its predecessor and the flange turned down properly this time; nice fold and the right way. So not all bad. Just the lower horizontal to make now and then time for trimming and welding.


Volvorsport - 15/3/13 at 12:29 AM

what wheeling machine do you have ?

any pics ...?


Not Anumber - 15/3/13 at 09:23 AM

+ 1

It would be very good to see the equipment you are using to fabricate these remarkable curved panels and even better to have a few pictures of you actually using it.


John Bonnett - 15/3/13 at 12:59 PM

I'm afraid my equipment's not very impressive

But in my workshop I have an Edwards wheeling machine, a shrinker/stretcher and a beading machine or jenny. I don't have any motorised or power tools like and Eckold or Pullmax.

Anyway here is my E.Wheel


And a couple of pictures showing the lower tailgate aperture panel being developed. I wheeled a bit of curvature into it before turning the flange on the jenny.

This is a picture showing the jenny with the side panel.



Pictures of lower panel




The next thing is to trim and turn down the flange for the gutter


John Bonnett - 15/3/13 at 05:18 PM

Well it started off quite well but went wrong at the end. I may be able to save it but most likely will start again after a bit of a rest.

John Bonnett - 18/3/13 at 02:01 PM

I have indeed started again and changed the approach to make it a bit easier. The crease on the bottom edge will now be in the deck panel rather than this one. This has simplified things no end because the gutter return and the crease no longer have to be perfectly aligned.





John Bonnett - 24/3/13 at 09:54 AM

Suffered a small set-back after having welded the lower gutter section onto the side roof panel I noticed that along its entire length, the weld was full of porosity; loads of tiny pinholes. Serves me right for using four year old flux! The odd thing is that the test pieces were fine.

I mentioned this to Trev D and strangely enough, using the same make of flux, he has also had problems but in his case cracking of the weld. I've been recommended a really good flux from TM Technology which I have just ordered up This is coming from the States so there could be a delay before I can crack on.


boober - 24/3/13 at 06:30 PM

is the crack at the start of the weld bead,or further in.

Trev didn't say but no crack on my weld Mark, just porosity.

There are many variables which will affect the weld and apart from the flux and filler not the least is the preparation of the material prior to welding. I perhaps wasn't meticulous enough in removing every trace of aluminium oxide. So, from now on I'll be more aggressive with the stainless steel wire brush and be absolutely certain that every trace of oxide has been removed.

Do you have photos of the weld and other progress? I ask because I have no idea how a body is made like this and have found this a very interesting thread.

If you look at the pictures I posted earlier in this thread, you will see that the roof is made up of a series of sub-panels which are welded together and then planished (smoothed) to finish the complete panel. Gas welding is preferred because the weld bead is soft and malleable and can be easily flattened back into the parent material.

Here are a couple of pictures of a weld I did on a test piece. The second picture shows good penetration on the reverse side of the weld.

My good friend Mark has let me have a sample of the TM Technology flux which I have now tried and not only has the porosity problem disappeared, the resulting weld has never been brighter or cleaner. So, that little problem seems to be behind me.

I managed to salvage the roof side panel and just needed to cut off the gutter just above the weld line. Picture attached showing new lower gutter ready to be welded on.


Once done, the rest of the roof panels will be finally trimmed and ready to be welded together.

How do you chose where to join the panels? when you flatten the welds does that not reshape the panel?


John Bonnett - 26/3/13 at 09:38 PM

Good questions, both of them. I'm only a self-taught amateur and we'd need Trev D to provide a complete answer. But I do know that choosing where to put the joints needs a bit of thought and planning. For minimum distortion during welding it's best to put the join on a curve but it needs to be an outward curve to be able to planish it. If it were an inward curve it would be impossible to use a body file. Generally, from a shaping point of view, joins would be needed in areas where there is a severe change in curvature or where a large amount of shrinking or stretching is needed. or just to reduce the size of the panel into a manageable piece. So there are a number of factors that contribute to the decision.

The second question is also bang on the nail. Flattening the welds and pushing the metal back into itself can easily stretch the material and change its shape. So it's good to keep the weld bead and the penetration to a minimum during welding and to file off the the bits of the bead that are proud before planishing. This leaves the minimum of work to do with a hammer and dolly.


John Bonnett - 3/4/13 at 01:17 PM

With all the roof panels formed, I'm now at the welding together stage so progress is being made; albeit slow.




John Bonnett - 6/4/13 at 04:41 PM

I've just completed welding the roof panels together and, amazingly, the assembly fits the buck so, happy days. There was hardly any distortion during the welding process which was an unexpected bonus.

I'm now faced with a job that I find really challenging; even more than the welding. The metal finishing, bringing up the lows and planishing to a nice smooth curvature. Hammer and dolly in the hands of a professional looks so easy but what job doesn't when carried out by a skilled man?



John Bonnett - 20/4/13 at 02:43 PM

Work has been progressing steadily with many hours spent bringing up the lows on the roof. We are not quite there yet but there has to be a point at which one says, that's good enough. I'm not quite at that point yet but not far off.

The panel rear of the quarter light was an interesting one to make with the reverse curve. I managed that one okay but I now have to make another one for the other side and I always find the second one more difficult.

The three tailgate aperture panels are now welded but I can't weld them to the roof until I've finished the planishing but more importantly until the panels immediately beneath are in place to provide rigidity.

A few pictures attached.

Thank you very much. I'm keeping the rain gutter because the two part gutter is the means of holding the roof on. All the other seams will disappear.

I'm going to re-model the rear end and make it more rounded and tapering. The final design depends on which rear lights I can find which fill the criteria. These are; Provide good illumination, fit on a curved panel, inexpensive and easy to source. The curvature of the rear wings will be tailored to the light unit. But which light?


John Bonnett - 27/4/13 at 04:14 PM

A bit more progress. I've made the rear quarter light aperture and the gutter, side panel and the aperture are now all welded up. Attached are a few pictures bringing everything up to date. Let's hope the other side goes as well as this one!








rdodger - 27/4/13 at 06:29 PM

Stunning work!

Can I ask a stupid question?

Since you are using the steel body as a buck won't it end up a few mm bigger than the original car? Therefore standard glass etc may not fit?


John Bonnett - 27/4/13 at 06:39 PM

Not a stupid question. You are quite right but the difference is only the thickness of the aluminium (1.5mm) so overall not a problem. However, the tailgate aperture will be 3mm undersize which will be okay and still allow clearance for the standard tailgate. But, the rear quarter lights will not allow the same approach. I had to remove the steel frame and replace it with the one I made in aluminium identical in size to the steel one so the opening window should fit. I say should because I haven't tried it yet.


rdodger - 27/4/13 at 06:47 PM

Ah good. I will tell the Mrs I'm not as stupid as I look!


TheGecko - 28/4/13 at 02:07 PM

John,
Hadn't noticed the updates typo this thread for a little while. Looking very good. Is that a timber hammerform that was used to make the quarter window aperture?

No it's just a template Dominic. I started with a flat strip of aluminium, folded a 12mm flange to a right angle and using the shrinker/stretcher, formed the profile. I then broke a line for the return using the jenny, annealed in the area of the fold and again with the jenny, tipped the flange to 90 degrees.


John Bonnett - 3/5/13 at 05:29 PM

Nothing spectacular to report but progress has been made. The passenger side quarter light panel is now formed together with the quarter light aperture. Today, the associated gutter was made. In order to fit the window aperture it is necessary first to remove the steel one because they are the same size as each other. This entails removing the spot welds; a job I'm not yet comfortable with. I've caused a fair bit of damage mostly to myself





John Bonnett - 12/5/13 at 05:18 PM

A couple more pictures to bring everything up to date. Apart from welding the panel surrounding the tailgate aperture to the main roof this part of the body is pretty much there.

With the roof just about done, we've reached the stage where I'm going to do my own bit of styling. The square tail and the external seams are going to disappear along with the pronounced haunch of the rear wing just aft of the B post. I've just sourced a complete bodyshell, (well a complete GT6 actually although in pieces) onto which I can hang the doors to see how the design will "Flow"

The picture shows the rear of a MK3 GT6 (not mine) and the taper of the cabin area flowing into a fairly flat deck which meets the flange of the rear wing. I'm going to try mimic this curve in the rear wings. The panel immediately below the tailgate will continue to slope down rather than becoming horizontal after the crease; something along the lines of an E Type.

So, a bit of thought and work to make a buck before any more panel work but I'll update as more progress is made.

Although it has been several months since updating, work has never stopped and the project is progressing well. Main reason for not posting is my inability to insert full size pictures. But until somebody lets me into the secret this is the best I can do.

With the outer skin removed the skeleton stiffening structure was shot blasted and primed. This revealed a lot more corrosion than expected with the knock-on effect of increasing the cost and time and blowing the budget out of the water. But, undeterred, we ploughed on.

I mentioned earlier that I'm taking a bit of licence with the design of the GT6 and making the rear end a bit more tapering and curvaceous.

I have recently acquired a pneumatic planishing hammer which has turned out to be one of the best buys I have ever made. It is very controllable and great for raising lows and shaping parts that are too small to wheel. Another benefit is that the air tool can be demounted and used on its own for flow forming. I made the number plate panel using it.

After a lot of thought I decided on round rear lights comprising inners and outer rings which can be LED. These are from the "Mix'n'Match range from Stafford. In order to mount them on my panel I rolled some cylinders and cut end plates. These were TIG welded together.

That's very kind of you Paul, thank you. I have no drawings to work to, I'm just carrying an image of what I want in my head.

Trev D is my friend and mentor and he is always ready to offer a telephone help line whenever needed. After a few words with him, it's like magic and all of a sudden the job goes right.

I'm absolutely delighted with the way the project is progressing and enjoying every minute of it.


rdodger - 28/9/13 at 10:13 AM

Awesome!

It's really starting to come together. The back end looks fantastic! Well done!


Fred W B - 28/9/13 at 10:17 AM

Thats looking fantastic, excellent work!

To insert full size pics what I do is:

Once the picure in is your archive, click into it to open it.
Right click to see the properties of the picture and save the properties to the clipboard
Go back to your post and click the "add image" yellow icon.
Paste the properties into the box that opens and enter

It helps to have the website open twice in 2 windows so youc can jump between your archive and the post you are working in.

Thier probabably is an easier way but that works for me

Cheers

Just to prove to myself that I can now attach a full size picture here we go.




I just love the bonnet on this car and will do my best to make something along the same lines for the project. I particularly like the feature near the windscreen that allows hot air to escape from the engine compartment and to blow onto the windscreen.

I'd like to thank you all for the kind things you have said about the project and for your encouragement. I'm really enjoying what I'm doing more and more as it progresses. I am very much a novice, completely self-taught and owe all I know to a number of tutorial videos made by various craftsmen. I'm slowly unlocking the secrets of wheeling up a decent panel and when it does go right first time it is hugely satisfying.

As far as the number of craftsmen making panels in this Country goes, there are more businesses than you might think all turning out panels and complete bodies to amazingly high standards. We can thank the high market values of vintage and classic cars as well as damage done while racing. Our own Trev D has a thriving business and is just one of several in the Midlands. Near me in Devon there are three or four and there is Geoff Moss (ex Aston) in Liskeard. And they are not all old-timers either. My friend Mark has just turned forty with a great future ahead of him.


John Bonnett - 12/10/13 at 04:36 PM

The return is now ready for welding to the quarter light panel and with the main wing panel bolted in place it gives a good idea of how the rear end will look. It is rather more tapered and rounded than the standard car, even the round tail models. The close up shot shows the wing bolted on but not nipped up because just out of shot is a double thickness of material awaiting trimming and welding.




[Edited on 12/10/13 by John Bonnett]


John Bonnett - 9/11/13 at 05:01 PM

Work has been continuing on the steel shell but not much aluminium panel work done since the last post. Mark is doing an incredible job and now the rear tub is joined to the floor and the scuttle/bulkhead has been trial fitted. Everything is inter-dependant and each part has a knock-on effect with door gaps and quarter light to windscreen frame gaps. We now have a situation where he is happy and some serious welding can begin very shortly.




When I visited Trev D a month or two ago, his colleague Martin was making a new bonnet for an Alfa TZ (Zagato). I just loved the shape and the curves of the bonnet and thought how good it would be if fitted to my project. Dimensionally the two bonnets are so close to each other this could be a reality Well it seems I can help Martin and in return he is going to make me a bonnet skin. This is really exciting and will be the best bit of my car by a country mile.

Yes it's absolutely mind blowingly beautiful. i can't wait either.
The flaps can be opened in the cockpit and the hot engine bay air is taken out just in front of the windscreen. Under bonnet temperature has always been a problem on the GT6 and i'm hopeful that this arrangement will be the solution.


Andy B - 9/11/13 at 06:26 PM

I dont think we have spoken on here before John but I have been following your build from the start and its one of those threads that always leaves me gutted when I reach the end of the latest update. Its totally absorbing not to mention incredible in its detail and your skill and I just love seeing the parts being formed from scratch. Keep it up and hurry up with the next update

keith777 - 9/11/13 at 08:25 PM

Can't believe I've only just found this thread,your work is absolutely brilliant
Can't wait to see the finished product !


John Bonnett - 9/11/13 at 09:30 PM

Thank you all very much for your interest and very kind comments. I'm still very much a novice metal shaper with an awful lot to learn. Fortunately my mentor Trev is a great inspiration and is very generous in passing on advice. It's probably lucky that he's in Northampton and I'm in Devon. Any closer and I'd be an even bigger nuisance to him

Once the sills are in place I'll be able to finish the left hand rear wing and make a start on the one the other side. To make things a bit easier for me I am avoiding putting in the straight creases or coach lines of the original design and sticking to flowing curves which I actually quite like. I'm not saying that the shape I've conceived is any prettier than the original, just easier for a beginner to cope with.

I'll certainly keep you posted with progress which hopefully will move up a gear once Mark has completed the restoration of the steel shell.

It is a six but a straight six. A freshly built 2.5 Triumph engine which I'm going to install six inches further back in the frame to aid weight distribution. For the moment, bodywork is everything and that's where I am focussed. The mechanics are pretty straightforward and should be a fairly easily assembly job certainly compared with the body.

Mark has overcome all the problems now and has achieved very nice shut lines of the doors against the sills, A post and windscreen. There is still a way to go yet but the rest should be much for straightforward.

For my part, I have welded the return to the lower wing section and welded the two rear wing section together. Once the sill is on, I can make the last two pieces to complete the wing.




Mike Wood - 17/11/13 at 09:00 AM

Hi John

An imaginative project with great workmanship; thanks for posting.

How are you going to mount the aluminium body panels? Keep the underlying steel structure - using aircraft/boatbuilding practice of barrier paste, such as Duralac ( http://www.intek-uk.com/duralac.htm ) to stop electrolytic action - combined with Monel rivets to make the structural join? Or go for superleggera approach of lightweight framework of small section steel tubes as used by Touring of Milan for 1950s and 1960s racing, sports racing and GT cars? ( http://www.velocetoday.com/images/january%2007/gt3a.jpg http://www.registrotouringsuperleggera.com/images/storia02.jpg http://www.moal.com/04_gallery/11gatto/01.jpg http://images.hemmings.com/wp-content/uploads//2012/04/TouringSuperLeggera_01_1200.jpg )

The project does remind me of 1960s works racing cars, either specialist Le Mans cars such as the works Triumph Spitfire coupes - http://www.canleyclassics.com/?xhtml=xhtml/workscars/default.html&xsl=workscars.xsl - or Austin Healey Sprite based Sprinzel Coupes (for racing and rallying): http://www.sebringsprite.com/pmo200.html ; or standard bodied cars using aluminium replacement panels to conform to more limited silhouette racing rules, e.g. http://www.sebringsprite.com/mark2sebrings.html

Your project does remind me of the work of Williams and Pritchard - http://www.williamsandpritchardregister.co.uk/ - who made a range of racing car bodies for open single seater cars, open and closed racing sports cars for a range of manufacturers e.g. Lotus but also initially for Sprinzel for Sebring Sprites. Also makes me think of Italian coachbuilders such as Scaglietti, Touring, Betone and Zagato building sports car, sports racing car and GT bodies on short 'production' runs. The English coachbuilding firms dating from the 1920s and 1930s, e.g. Hooper, Gurney & Nutting, always seemed to concentrate on large saloon cars and limousines, with only new concerns springing up in the 1950s and 1960s working on sports and racing car bodywork in both aluminium and fibreglass.

Engine - surely just use the 2litre straight 6 of the GT6 tuned?; or for more torque could put in the 2.5 litre engine from the 2500 saloon. Guess you've already checked out info on websites: Chris Witor Triumph spares, Canley Classics and Triumph Six Sports Car Club? Also people putting the 2500 engine into Triumph Herald Vitesses.

I enjoyed reading your Fury build blog including all your production engineering - how you solved all the detailed design/fabrication issues for small components and fitting it together properly. So this project perhaps not such a surprise!

Best wishes
Mike

John Bonnett - 17/11/13 at 10:15 AM

Hello Mike, very nice to hear from you and to read your detailed reply. The Phoenix you mention seems a lifetime away now. It was a big mistake putting the Cosworth engine in. The sheer weight of the unit spoiled the balance and handling. I believe it now has a K series engine which I imagine will have transformed it into a much more nimble car. I can never understand why people fit heavy lumps up front in a 7 but perhaps like me, they just had one!

The GT6 has a steel skeleton frame which I am using to fit the aluminium panels to. I do have Duralac and also some plastic tape which will insulate the dissimilar metals and help to prevent corrosion. Monel rivets are a good idea too. The roof , tailgate aperture panel and the rear quarter light panels will all be bonded to the steel frame. The rear wings as you can see will be bolted on. I'm going to fabricate a steel supporting frame for the bonnet skin but at the moment I've not decided whether to bond or clench. I'm quite excited that Trev D has agreed to make the bonnet skin for me. It should take several months off the build and it will really enhance the look of the car.

Work is progressing well on the steel shell but still a fair way to go before it is finished. I've formed quite a lot of the panels already and hopefully it will all come together quite quickly once the shell is done. I don't want to hang around with this project and am looking to have it on the road by the middle of next year. Spa in May was my target but I don't think that is realistic although I shall try.

I shall be using a Triumph 2.5 litre engine just because I have one. Otherwise, it would be a 2 litre. I also have an overdrive gearbox and a 3.27 diff. The rear suspension will be rotoflex.

I have two more sub-panels to make to complete the rear wing and once they have been formed and welded together the rear left hand three quarter will be finished.

Will keep the thread updated. Thank you for your interest.

regards

John

John Bonnett - 5/12/13 at 07:09 PM

Mark has done a fantastic job and the steel shell is pretty much there which is now allowing me to press on and form some more panels.

I took the opportunity today to dust off all the panels that I've made so far and place them in position. Not only is it encouraging it is also a measure of the progress that has been made.

I have to make two more sub panels to complete the rear wing.




John Bonnett - 9/12/13 at 05:49 PM

A couple more pieces in place ready for scribing, trimming and welding together. This leaves just the sill extension to make which will then finish the panels for the rear wing.


John Bonnett - 21/12/13 at 06:49 PM

Although there is a fair bit of planishing to be done, the left hand rear wing is pretty much there apart from the sill extension piece which should be fairly straightforward (famous last words!)

I'm making the rear valence in three pieces, the return which fits to the steel boot floor, the centre single curvature piece and the end panels which have quite a lot of shape. Here are a few pictures which bring everything up to date as of today.




John Bonnett - 30/12/13 at 06:11 PM

With the Trials car to prepare for the Exeter which is this coming weekend, time has been a bit limited on the project. But, a bit of progress which is better than no progress. I've formed both ends of the rear valence and welded them to the centre section and the trial fit looks quite promising. Just the return to weld on and that's the panel finished.

The aluminium will be dressed over the inner wing return and bonded to it. So there will be no wheel arch extension as on the GT6.

I've taken a bit of licence with the design not because I think I can improve it but just to make things easier for a novice metal shaper.


John Bonnett - 18/1/14 at 05:16 PM

Work on the shell and the panels is still progressing nicely. A bit more remedial work needed to the scuttle but for the shell the end is in sight and I've broken the back of the panelling. Here are a few pictures bringing everything up to date.




ceebmoj - 18/1/14 at 06:13 PM

Looks great. Is the body going to stay on this floor pan or are you making a tubula chassis? If it stays on this floor pan how do you deal with galvonic carosan where the steel and aloy meet?

Good questions there. Essentially it is still a GT6 with aluminium panels so we're sticking with the original chassis. I'll be using Duralac which is a zinc chromate paint to insulate the aluminium from the steel and help prevent corrosion. The panels will be bonded to the stiffening structure using panel adhesive which should also help the insulation. in any event, it will last me out!


ceebmoj - 18/1/14 at 07:01 PM

I used duralac with bolts on the Elise should it be used with steel bolts in an alloy block?


John Bonnett - 26/1/14 at 09:38 PM

The panel work is still progressing quite well with the left hand rear wing finished apart from forming a return to fit the inner wing and B post.

The rear valence has to be welded to the panel adjacent to the tailgate aperture before the number plate panel can be welded on.

That's really kind of you. Thank you. Welding up small panels is relatively easy and straightforward but welding the number plate panel will make for a very large and cumbersome pice which is going to take me right out of my comfort zone. Whre is Trev D when I need him?


Jimmy-boy - 6/2/14 at 08:55 PM

wow just wow


John Bonnett - 9/2/14 at 02:45 PM

A little more progress to report with a couple of pictures.

Initially, my idea was to form a scuttle in aluminium hence the reason for using a MK2 bulkhead with the detachable windscreen frame. The plan has now changed and I intend to stay with the whole thing in steel. I see no reason to keep the screen frame as a detachable item which with rubber seals top and bottom will always be the source of potential leaks of both rain and wind. So it's going to be welded in permanently which hopefully will add to the stiffness and integrity of the whole shell. Here are a couple of pictures showing the lower intermediate piece formed to suit the frame and the scuttle. The scuttle was cut to accept a joddled edge of the mating part leaving a flush joint. The top piece is work in progress and yet to be finished.





The panel adjacent to the tailgate aperture is now welded to the lower rear valence and the assembly trimmed ready for welding in the number plate panel.





So tomorrow, is the day set aside to tackle the big challenge (for me) of welding in the number plate panel. I hope to have some more pictures very soon.

Thank you Steve. No at the moment, I don't have a picture of the car with the tailgate shut. In order to get a realistic picture of what it will look like, I really need the back end assembled, perhaps after tomorrow. Let's see how it goes.

John Bonnett - 12/2/14 at 07:57 AM

The panel is now successfully welded in and because I was able to do a lot of the welding with the assembly fixed to the car everything kept its shape and the whole job proved to be very much easier than I feared.


I'll post a few more pictures once the panel is planished and fitted back onto the car.

[Edited on 12/2/14 by John Bonnett]


John Bonnett - 12/2/14 at 11:03 AM

The panel needs a lot more planishing but I was anxious to check that despite the welding, it still fitted the car and that the lights still fitted into their apertures. Fortunately, all is well so I can relax now.


rdodger - 12/2/14 at 02:54 PM

Looking really good; I notice you have the tailgate attached...any pictures of the rear end with it closed?






Here we are Steve. The fit and shut lines leave a lot to be desired but at this stage I'm happy to settle for the fact that it latches.

John

I've spent a bit of time on the passengers door working to achieve a decent shut and panel gap. The gap can be further adjusted during skinning the doors with aluminium but it's been good to get it as close as I can.

The main problem was the unsupported part of the B post to which the striker plate is fixed. Once I'd put a brace in place, the problem was solved and the door latched nicely.

Nothing fancy. 1mm mild steel with three holes using hole saws, a couple of swage lines and the top and bottom edges have a 12mm flange turned at right angles. I didn't like adding weight but the stay was needed.

For the swage lines do you beat the steel over a bit of rod or do you have a wheel to form it.

I've got a Jenny with the tooling to form a swage line and that's what I used. But it would be quite easy to sit the job on two pieces of plate with the correct separation and using a bit of round bar hammered from the top to form the trough will achieve just a good a job.

If you are interested in metal shaping using just hand tools David Gardiner's CD is excellent and you could also have a look at 2cv's tutorials on this forum.


John Bonnett - 5/3/14 at 09:30 AM

The right hand rear quarter light panel wasn't quite right so I re-made it and I'm very pleased i did. It is much better this time and I'm happy with the result


Meanwhile Martin, Trev D's colleague has made good progress with the Alfa bonnet and he has just sent me these two pictures.

Nothing spectacular to report but work is still going ahead. I spent a bit of time fabricating a section that mates the windscreen frame to the roof and that was an interesting exercise in steel. In the end it all fitted quite nicely and puts a lot of strength into that area.




I have also fabricated a stiffening section to fit in the boot which has made a huge difference to the way the tailgate shuts




I've been thinking about pick up points for the rotisserie and have started making a frame at the rear. as a basis I'm using two engine stands which I bought new for the amazing value of £33 each.


No further news on the bonnet but most of the work is done with just the welding to complete the two halves. At this point I'll have to mark it up where it needs trimming (so that the width is correct) and then Martin will have it back to finish it.

So all progressing well but never as fast as I wish.

You really are very kind and the support I receive does give me a lot of encouragement and a tremendous boost. However, I don't really have much in the way of skill to impart. I didn't take up metal shaping until I was sixty and I'm totally self-taught. I'm now in my seventies and thoroughly enjoy what I'm doing. I really do wish I'd taken it up earlier in life because I can think of nothing more satisfying than creating a beautiful shape from a flat piece of metal.

Thank you once again for your kind words.

regards

John


John Bonnett - 12/5/14 at 06:10 AM

The shell is now at a stage when it can be removed from the chassis without any worries about stability and distortion. This is now allowing me to start on the dummy build up of the chassis. Dummy because it will all have to be dismantled so that the chassis can be shot blasted and powder coated.

Some of you may be interested in the rotisserie I made quite simply and cheaply so that the body can be rolled over. The video is all very amateurish I'm afraid but here's the link:

https://www.youtube.com/watch?v=JNlp6Vsc0Qw

I'll put some more pictures up once the engine and gearbox are in the chassis.

Fantastic work as always John!

Really enjoy seeing the updates on this.


John Bonnett - 8/8/14 at 06:38 AM

Thank you for your interest chaps. Holidays have slowed the progress but the steel shell is finished now and ready to go back onto the chassis. The underside and insides have been seam sealed and the underneath sprayed with Stonechip.

I've changed my mind for the final colour which was going to be Rosso Red but will now be French Blue. The only reason is that although I love the red there are just too many red cars (in my opinion). Colour is very subjective and very much a personal choice. I really liked French Blue on my GT6 and am very happy with the choice of colour. I've used an enamel tractor paint for the inside which is fairly close to colour the body will be. In any event it will be covered by either carpet or upholstery.

Petrol tank is now modified and ready for powder coating. The GT6 MK2 tank has the filler neck in the place I need for my set up but the tank was badly corroded so I cut the piece out of the MK2 tank and welded it to a MK3 tank which is in very good condition. I'm going to use the redundant neck for a breather.

John Bonnett - 10/8/14 at 04:43 PM

Looking back through my posts I realise that I've been quite liberal with the pictures but perhaps a bit short on text so hopefully the following will tie everything together and bring things up to date.

The initial aim was and still is to build a lightweight GT6 where the steel panels are substituted for aluminium. The standard car has a nice skeleton steel frame that I'm using to underpin my build. I have taken a few liberties with the shape of some of the panels partly to make things easier for me to form and partly because I'm aiming for a more rounded look with the absence of external seams.

Building the shell was a huge task because, not wishing to butcher a perfectly good shell and risk the wrath of many I started with sections from three different vehicles which were joined together and many new repair panels fitted. This was a very costly and time consuming exercise but at the end of the day we have a very solid and rustfree body as the basis of the build.

In the interests of handling and sheer driving enjoyment I am using a four cylinder Spitfire engine rather than the much heavier six. Powerwise we should have a similar output to the six although granted not as torquey but coupled with a lightweight body the car should be nimble and actually want to turn in to a corner. I'm using GT6 brakes and suspension including Rotoflex at the rear which eliminates virtually all camber change. Adjustable dampers all round. The very much cheaper option would for sure have been to fit a Zetec or other lightweight modern engine but I really want to keep the car as a Triumph.

I've built up a rolling chassis and during this coming week the body will be transferred from the rotisserie onto the chassis for the panels to be fitted. All are made except one rear wing which having made the reversible buck and the wing for the other side should be fairly straightforward.

Once the panelling is finished the body will come off the chassis so that the chassis can be shot blasted and powder coated.

So that brings everything up to date. My thanks to all of you who have expressed an interest in my project and have taken the trouble to read the write ups.

John


John Bonnett - 18/8/14 at 07:19 PM

The body is now back on the chassis and pleasingly every mounting bolt hole on the body lined up perfectly with its opposite number on the chassis. The doors were trial fitted and much to my relief, they still fit their apertures.

I'm spending a lot of time trying to achieve a decent shut line between the tailgate and its surround. This is proving difficult but not impossible. I need sufficient gap to allow for the thickness of the paint. the next phase of the job is going to be slow and painstaking I feel but this is the bit that everyone will see and so it does have to be as good as I can make it.

John Bonnett - 23/8/14 at 05:17 PM

A bit more progress made over the last few days. The roof is now sitting nicely in place and to my eye is symmetrical. I found this a very difficult panel to make and I have to say how pleased I am with how it has turned out. The tailgate surround is now in place and ready for welding to the roof.

A couple of pictures attached to bring things up to date.

Mark, I can tell you that apart from the old sand running through the hour glass at an alarming rate, retirement is the very best time of my life. I can just play every day. I've been retired sixteen years now and it just gets better. But having said that, don't wish your time away. No time is better than the present.

I had my 40 year crisis and got a big bike, now enjoying my early 50's spent the last few weeks building my project shed for hopefully a good few years of tinkering 10 tons of concrete and two pallets of bricks later and I am awaiting my oak frame to arrive

Also purchased my sprinting clothes today, I have finally reached the point that I can start spending on myself.

John Bonnett - 27/8/14 at 06:34 PM

A bit more progress today. One leg of the tailgate panel is now tacked and ready to be fully welded. The complete panel is getting a bit difficult to handle now.
[img][/img]
[img][/img]


John Bonnett - 28/8/14 at 05:28 PM

Seems like my misgivings about the panel never fitting again were unfounded, much to my great relief. Once the tailgate panel was welded onto the roof it is quite surprising how stiff the assembly is. There's quite a bit of planishing needed to finish the job but it is encouraging to know that the panel is going to be okay. This was one of the parts of the job I was dreading.

A few pictures bringing this up to date.

Ah, the front, funny you should mention that! I've tried to restrain myself from doing anything with the bonnet. Trev's colleague has made a wonderful job and it is now waiting for me to work out how to fit it. I did give in to temptation and offered it up a week or so ago and I think once the surplus has been trimmed off and it sits several inches further back towards the scuttle it's going to be fine.

John Bonnett - 1/9/14 at 07:54 AM

I've spent ages on the tailgate fit and panel gap and it's now just about as good as i can get it.

John Bonnett - 5/9/14 at 07:12 AM

I've now spent many hours with a flipper and weight working on the tailgate aperture panel bringing up the lows . In my last post i said it was as good as I could get it but I keep nadgering away at it. Where do you stop?

I ordered up a standard roof finisher which I hoped would fit because if it did it would make a nice job of covering the front edge of the roof and clamp it tightly to the mating panel. The finisher is just a U and it needed opening out a tad because my set up is a mm or so thicker than on the original car. Once this was done, to my great relief, it tapped on nicely. So another hurdle over.


[Edited on 5/9/14 by John Bonnett]


John Bonnett - 18/9/14 at 08:22 AM

I've done a bit more and following two coats of etch primer and a top coat of French Blue the roof is now bonded on. I used two pack panel adhesive. The roof flanges were clamped down tightly whilst the adhesive went off.







John Bonnett - 23/9/14 at 03:09 AM

The rear panel is now bonded on to the steel frame and tack welded to the roof panel.




John Bonnett - 27/9/14 at 08:44 PM

I've just finished the bonding on of all the panels the last being the two rear quarter light panels. Next up is to make the final weld across the width of the car making all the panels one.



John Bonnett - 28/9/14 at 08:03 PM

Clamps are off and all the panels well and truly bonded on. Certainly no shifting them now. These modern boding adhesives are formidable. The rear quarter light panels are now tacked waiting for the final TIG weld to fully weld the whole assembly together.





ceebmoj - 28/9/14 at 08:13 PM

looks great, what are you going to do next?


John Bonnett - 28/9/14 at 08:17 PM

Next up is the driver's side rear wing which will complete the rear bodywork. After that it's going to be the bonnet which will be a project all on its own.


John Bonnett - 4/10/14 at 06:19 PM

The in-situ TIG weld has now joined the panels into one making the new aluminium body shell and that is a real milestone. I've spent a bit of time today metal finishing which I've found very pleasing and rewarding.



John Bonnett - 24/10/14 at 04:36 AM

The weld across the rear of the car which joins the panels together is now metal finished and the rear lights trial fitted. The modified tank is also trial fitted. I've retained the MK3 filler neck on the far side to incorporate an air bleed. Here are a few pictures bringing us up to date. And yes, I do realise the steering wheel is upside down. This is only a trial fit. My main concern was that the column when clamped up, lined up properly for the shaft to fit through the hole in the bulkhead. Fortunately all was well and everything went together nicely.

Very nice to hear from you Nick and Stu and thank you so much for your encouragement which is very much appreciated. Trev D is coming down this weekend and I'm hoping that he will be able to give me a bit of guidance on adapting the Alfa bonnet. It's going to need a fair bit of re-shaping at the scuttle end but nothing too serious, (I hope!). Once that's been sorted we'll be well on the way.

How is your project coming along Nick?

My wife and I are taking the trials car to France next month just for a couple of day's holiday. The French really love the car particularly when I tell them it has a 205 GTI engine. I'll pop some pictures up when we get back. We are now running a 1.9 engine coupled to a 306 diesel turbo gearbox and this coupled with 185 80 15 tyres gives 30mph @ 1000rpm in fifth. It's an awesome cruiser.

Hi John

My project has reached the stage of a205 gti on the drive which is good for the occasional boat here and there. I also have a bare 205 shell in the garage which I'm slowly striping of paint and underseal and contemplating what to do with it.

Family life and work allow no real project time at present and an impending house move with a list conversion to do will slow it to a stop. The bonus is a large garage/workshop to fill with more parts while I work on the house.

Have you any recent pics of the trials car? I'm sure others on here will be equally interested to see it.

Nick

I was so privileged to have Trev D spend a day with me to help me with the project. He spent some time tidying up my shoddy workmanship and he has transformed the tailgate area. It shut better and the shut lines and gaps are very much better. He then turned his attention to the bonnet and after re-working the up-stand at the scuttle end we were able to offer it up. It all looks quite promising.

Today, I have made a start on the right hand rear wing which will be the last panel to finish the job.

John Bonnett - 2/11/14 at 04:55 PM

The wing buck I'd made for the other side is reversible and turning it round worked out quite nicely with not much work being needed to mount it to the body.

The return started as a flat piece of sheet folded to a right angle and then shrunk and stretched as necessary to match the shape needed. A lot of shrinking is going to be needed to give the necessary taper. That's going to be quite challenging!

Perhaps we should have a Plan B then Paul. I know how much you love polishing so fancy coming down and buffing up the ali?


John Bonnett - 7/11/14 at 07:04 AM

The return took a bit of shrinking but the annealing did the trick and all turned out quite nicely. Two wing sub panels in place ready to weld together.



John Bonnett - 7/11/14 at 04:49 PM

Slow progress today but I've gas welded the main wing sub-panels together ready to weld the assembly to the return. That will be a weld of about seven feet.


John Bonnett - 16/11/14 at 07:03 PM

I'm pleased to report a bit more progress since my last offering. On this side I've decided to form the B post return separately rather than tap it over as I did on the other side. This has the advantage that the bend is crisper and the actual B post won't need a supporting stay to withstand the tapping round. Starting with a flat strip I put a fold in not a right angle but enough to break the line and then I annealed the bit that would need stretching. This minimises the risk of the aluminium splitting. using a combination of shrinking and stretching the return was quite easily formed. The remaining sub-panels were gas welded to the main wing section. All that is left to complete the wing is to weld on the return and tap the return round the wheel arch.

You have no idea how much I appreciate the encouragement and kind words I receive on this forum. Thank you so much.

I really feel we are on a roll now with the end in sight. This wing will see the bodywork finished just leaving the bonnet which Trev D's colleague Martin is going complete when I have made the supporting frame and worked out where it needs welding. All quite exciting.

John


rdodger - 16/11/14 at 08:51 PM

I think we all look forward to the updates and can't wait to see it finished!

Can I ask about the welding? Is it all gas welded? If so why is it gas rather than tig? Sorry if you have already told us earlier in the thread.

I've gas welded most of the panels because the weld bead is very malleable and the heat affected zone is annealed. This makes the planishing and further working of the panel easier than if they had been TIG welded. The long weld across the rear of the body below the tailgate aperture is TIG welded because it would have been difficult to wash the flux off if it had been gas welded. I shall also TIG weld the B Post return onto the wing because this will lead to minimal distortion and no further forming will be needed. I'll just need to sand the weld bead flush. That's the plan anyway. I hope to report some good news tomorrow night!


rdodger - 16/11/14 at 09:35 PM

The edge lips under and is bonded and countersunk riveted to the inner wheel arch. I've cut a piece of plywood that I shall use to clamp the aluminium tightly against the inner wing and then it can be tapped over with a nice tight bend. I did the same on the other side and it worked out well. Hopefully some pictures tomorrow.

Thank you Mark, yes I hope so. I'm hoping to do three events in France next year and also get up to Donnington for the TriumphFest so there's no time to lose.


John Bonnett - 17/11/14 at 07:02 PM

Well, I had to work hard today but the wing is pretty much there now with just a bit of tidying needed. The picture show the B post return in place over the top of the wing ready to scribe and cut and trim. The second the wing tacked to the return. The third fully TIG welded and the final one the return starting to be tapped over against the inner wing.

John Bonnett - 18/11/14 at 09:09 AM

Thanks guys, to be honest it ain't that great but you know the right things to say

It will be painted I'm afraid because the car is going to be used and nothing corrodes aluminium better than a salt/water solution.


Mr Whippy - 18/11/14 at 12:42 PM

I'm assuming and sorry if this has been already covered before in conversation, but is there a barrier between the steel and aluminium panelling? I notice that some of the recent pictures seem to show the aluminium being on top of what appears to be bare steel.

It's just I've just spent the last few months and heaps of cash replacing corroded aluminium panels on a landrover where they had been contacting the steel work or bolts or washers...it's a nightmare


mark chandler - 18/11/14 at 01:01 PM

John

You started off with gas welding, now it's TIG what changed and why?

I once tried gas on thin ali sheet, trying to repair a rangerover tail gate, everything fell apart in molten blobs

John Bonnett - 27/11/14 at 01:40 PM

With the body panels all made and fitted I've been turning my attention to fitting the bonnet and making a a tubular steel frame for the air intake aperture and around which the aluminium will be dressed.

I'm making a simple plywood buck to hold the bonnet in place and the transverse stages will be notched to locate the tubes for the bonnet supporting frame. Here are a few pictures.






rdodger - 27/11/14 at 02:34 PM

No pressure John!

You can always have another bonnet made

John Bonnett - 27/11/14 at 06:39 PM

A lot of time today spent looking and adjusting so not much to show. However I have made a longitudinal sweep and from that cut the centre station for the buck. Just a couple of pictures I'm afraid.


John Bonnett - 7/12/14 at 04:50 PM

Quite a while since I posted any progress but I've been beavering away. Not a huge amount of perceived progress but I've spent a lot of time measuring and fitting in an effort to get the bonnet sitting in the best position with respect to the body and the general appearance.

The buck is now finished and this provides some reliable datum points as well as a firm base to support the two bonnet halves.

Right from the outset, it did look as if there was too much shape in the bonnet where it meets the door so I took the bull by the horns and cut a Vee stretching from the door end a foot towards the front. I then tapped the aluminium down onto the buck which closed the gap and then welded it up. Phew! Glad that's done. The transition is definitely much closer now so it was the right thing to do.




ceebmoj - 7/12/14 at 05:25 PM

Great progress. Will the steel opening form be left in why'd bonnet? Or will it come out once the shape is there.


John Bonnett - 7/12/14 at 05:45 PM

A good question. The steel hoop is actually a fundamental piece of the bonnet supporting frame. There will be two longitudinal legs coming off the lower part of the hoop going back to the hinges and two longitudinals inboard of the headlights going back from the top of the hoop to a transverse tube near the scuttle. The aluminium will be dressed around the the hoop which will secure the bonnet to the frame in that area.

The buck itself was quite fiddly and time consuming to make but well worth the effort as all I have to do is to notch out the transverse stations to lay the tubes in and they should be located perfectly. Fingers crossed on that!

I'm going to make a start on the hinges tomorrow. I've been given some really nice oilite bronze bushes which are absolutely ideal. They have an 8mm bore and the shank fits nicely inside the 5/8" tubing that I'm using. Deep joy


John Bonnett - 9/12/14 at 09:50 PM

I've now made the hinges for the bonnet which are a very simple affair but hopefully will be up to the job. The bonnet itself is light and the inner wings will be fixed to the chassis rather than an integral part of the bonnet. So the hinges will never have a huge load to cope with. The aluminium sweep represents the bonnet and shows that the opening will be sufficient to access the the engine bay.



stevebubs - 9/12/14 at 10:34 PM

Holy cow .. not really looked at this site properly in a while and I see this... coming on really well, John...

It's coming on nicely Steve and early in the New Year, I've got the added bonus of Trev D's colleague Martin who made the bonnet coming down to my workshop to make sure it fits properly; all very exciting.

That's really kind of you Nick, thank you.

Trev |D's mate Martin reckoned with the hinges where I've put them the bonnet doesn't open wide enough and of course, he is right. The sweep looks as if the open position is more than adequate to give good access to the engine bay but I'd not allowed for the restriction of the wings. So, today I've moved the hinges three inches towards the front and I think that has done the trick. I'd only tacked the clevises so it was no great problem to get them off.

I've also started bending the tube for the bonnet supporting frame so we are still progressing albeit slowly.


mark chandler - 11/12/14 at 09:25 PM

I,m only seeing a little 4 pot under the bonnet, I thought gt6's were all 2.0 straight 6's unless the 2.5 had been transplanted.

Are you planning anything under the hood John?

Quite right Mark, but the sheer weight of a Triumph six would negate everything I'm trying to achieve in building a lightweight nimble car that is fun to drive on the road. The GT6 is a great tourer and we took ours to Scotland, France and Spain and it was superb. But this car is different and my target is to achieve the handling and sharpness of a Caterham 7 and no amount of moving a six cylinder engine back in the frame would come anywhere near that.


adithorp - 12/12/14 at 08:49 AM

The GT6 grew out of the 4pot Sptfire LeMans coupe anyway.

More great work, skill and progress John.


John Bonnett - 27/12/14 at 06:42 PM

Work stopped for a short break a couple of days before Christmas but I managed to get the bonnet supporting frame tacked together and the over centre catches together with their mating parts trial fitted. I was really pleased to discover that the reinforcing bonnet corners which accommodate the rubber locating cones are available as a Heritage repair panel. This was a huge benefit and saved a colossal amount of time. A few pictures follow.





ceebmoj - 27/12/14 at 08:14 PM

Great progress. Have you seen the hinge on project binky, it could make removing the front end for work very easy?

I've just watched the latest episode and that solution is so neat and above all, simple. Sadly, I didn't think of it and I'm too far down the line to change now. But all I have to do is remove a couple of R clips and pull out the hinge pins to remove the bonnet. Not so easy as Binky but do-able.


John Bonnett - 30/12/14 at 10:02 PM

I've decided to leave the bonnet supporting frame just tacked for the moment. Trev D's colleague Martin is coming down soon to do some work on the bonnet skin and if he recommends that I change the frame it will be easier if it's not fully welded.

So I'm now starting on the cooling system which uses a Golf radiator and a MK4 Astra header tank. The VW radiator is efficient, light and above all amazingly cheap. I bought a shroud complete with fan to suit off Ebay. The radiator is located on the base by two spigots which are accommodated by a pair of simple brackets fitted with rubber grommets to provide the necessary cushioning. Next was to cut out a cardboard template for the ducting which will be transposed onto aluminium. The ducting will be screwed to the radiator and will hold it rigidly in place. It will be fun folding the aluminium with many opportunities for mistakes.

John Bonnett - 10/1/15 at 04:43 AM

Yes, the ducting is finished now after aborting the MK1 on the grounds of it being too heavy. Pic 1 The MK2 is a lot better and uses a frame of 25 x 25 x 1.5 extruded aluminium angle with the panelling in 1mm. I had to add stiffness by putting in a few swages but I think it will be okay. I have also made the crossbar that fits across the middle of the air intake aperture frame. This started out as a piece of 1.2mm stainless sheet 32mm wide folded into a Vee. In the centre is a stainless backing plate to accommodate the Triumph badge.

Good point Adi. I could also do with a diffuser and some sort splitter at the front. Then onto fitting the supercharger.

Motivation seems lacking at the moment. I haven't even washed it after Brands Hatch!

Can we look forward to the fitting of the bonnet soon?

Indeed we can. Martin, who made the bonnet skin has spent the day with me and has made terrific progress. The skin has been clecoed to the frame so that it will always go back in the same place, one headlamp aperture cut out and one headlamp bowl made and tacked together. It was very pleasing to see it, fixed to the frame hinged open. There will be a gap now while Martin takes the assembly away to finish in his workshop when time permits.

John Bonnett - 11/1/15 at 07:23 AM

Thank you all for your very kind words and encouragement. I'm so lucky to have Martin's help without which I would have been totally out of my depth. It was quite amazing to witness his accuracy, and speed of work; a real privilege to be in the company of a master craftsman. All a bit of an anti-climax now that he has finished and I'm back on my own. But everything should be pretty straightforward from here on in. Next weekend I'll have the body off the chassis and during the following week strip it down and get it over to the painters to be shot blasted and powder coated. In the meantime I can be making up the wiring loom so plenty to get on with.

I'll keep you posted and thank you all for your interest and encouragement which i find absolutely fantastic. Thank you.

John


John Bonnett - 2/2/15 at 07:26 PM

Since the last offering the body has been removed from the chassis, the chassis stripped of all the running gear and taken for shot blasting and powder coating.

Work on the wiring is under way with the rear loom finished. To clip it to the car I've sourced some nice little tie wrap saddles that can be screwed or riveted. The tie wraps allow the loom to be demounted if required.



I've painted the bulkhead and it is now ready for the master cylinders and all the other bits and pieces that sit on the scuttle shelf.



I'm trying to keep the car simple and the dashboard that I've just made does, I believe, fit into that concept. There will be a couple of other gauges mounted on a sub-panel behind the steering wheel but nothing over the top.


John Bonnett - 8/2/15 at 01:48 PM

Before the loom can be finished the hardware has to be sited so that the various wires can be trimmed to the right lengths. So, the wiper motor is in position, the dash instruments and the heater. I'm using a T7 modular heater similar to the one in the trials car which works very well. The heater is available with a wide choice of blanking plates and outlet stub pipe diameter. The bulhead adapter, also from T7 is nicely made and with the pipe spacing matching the heater inlet and outlet pipes it allows a neat installation.





[Edited on 8/2/15 by John Bonnett]


John Bonnett - 27/2/15 at 07:24 AM

The chassis went together really quickly and is now fully built and awaiting the engine. The secret to the quick reassembly was that sections were removed after the dummy build as assemblies rather than individual components. And the brake and fuel pipes were already formed.

I've been told that the diff mounting plate should be fixed with Wedgelok bolts which are a special type that is self-locking. Standard bolts have a tendency to work loose, come out and jam the propshaft; not nice! I've been unable to source them so I've fitted new star washers and wired the heads. I'm hoping that will do the trick.

The new bonnet catches arrived today and I've been able to trial fit them to the aluminium recesses that I made a week or so ago. These will be trimmed and welded into the bonnet while being located by bolting through into the steel backing plate.


John Bonnett - 18/3/15 at 08:09 PM

Well, I now have the engine, the gearbox is fitted and all is bolted in. So pleasing progress. I've decided to change the diff to a better ratio and before doing that, I've drilled and tapped the casing for a drain plug. Early cars had a drain plug but this was later discontinued. However, the boss is still present and being cast iron easy to drill and tap.

There is a copper washer there sitting under the plain washer. You can just see it.

That'll tend to leak between the head and steel washer. You should have just the copper washer.

Looking good though. Best looking GT4 I've seen

Yes you are right, it will leak. I put the plain washer there to give a bit more area to act on the copper washer but unless the plain washer were welded to the bolt there is no seal. So thank you Adi. I'll sort it.

Hi John

A flange bolt (non serrated type) would give a larger surface area to seal on.

Keep up the good work.

What size/thread is the plug? There might be a sump plug that's right for it. They often have a flange... though there's plenty that just had a hex.

It's M8 Adi. I'm sure that a copper washer and flange bolt will be fine.


John Bonnett - 23/3/15 at 07:34 PM

A bit more done today. The dashtop crashpad and the demister ducts are in and piped up to the heater. It was a trying job totally because of the inaccessibility of the fixings underneath. But we got there in the end.

A much more pleasant job was the trial fitting of the oil cooler. I welded up a simple U shaped frame from extruded rectangular aluminium tube and picked up on the mounts in the cooler. The frame and the ducting are away tomorrow for powder coater.


John Bonnett - 28/3/15 at 08:40 PM

The radiator ducting came back in record time from the powder coaters; just twenty four hours turn-round. Terrific service and quality. All fitted now together with the oil cooler.

We got the body back on this afternoon which went very easily thanks to a party of willing lifters. It is all bolted down now together with the steering column. Now the body is on there are loads of things I can get on with not the least being finishing the wiring.



rdodger - 28/3/15 at 08:53 PM

I really can't now it's so close to completion. This project totally has taken me over and I'm working on it pretty much full time . With the steering column in, all the plugs and sockets can be connected and then it's the moment of truth. Connect the battery time. How many, if any of the circuits will actually work? Or will there be an almighty smoke up? Finger crossed. I'll report back.

cheers

John


John Bonnett - 13/4/15 at 07:55 PM

Plumbing on the cooling side is now finished and the system filled with coolant.


The wiring would have been finished by now but I made a late decision to to give the dashboard its own loom connected by plugs and sockets. It took a few days but it will be worth it not to find, once it's put back that a spade had pulled off one of the terminals which always used to happen on my GT6.


John Bonnett - 15/4/15 at 08:19 PM

At long last, the wiring is finished and the dashboard fitted. Martin has done his bit on the bonnet which I am absolutely thrilled with and cannot wait to see it fitted on the car.

Nice to hear from you both and thank you for the encouragement. I'm collecting the bonnet middle of next week. I'm really hoping that there won't be a clearance problem with the Webers. I set it up with the SUs on the other engine because at that stage I didn't have the new one.

I'm moving ever closer into a start-up situation. The tank went in today and also the alternator the alternator so that the water pump is driven.

I finished the exhaust system yesterday and connected the Rotoflex tie rods; both fiddly and time consuming jobs but done now.

First of all VERY GOOD WORK....

On a side track, Nice Tail lights; could you elaborate on Brand, Model, Supplier and Cost??
Thanks in advance.

As an ex- GT6 owner it's been fascinating watching progress, John.
Looks like you could do with a genuine gear-knob?
If you don't have one let me know by pm and I'll donate one.
Cheers, Pewe10

Pewe that is really kind of you, thank you. I do have the overdrive knob but probably won't fit it until after the tunnel is in. I really appreciate your kindness and that of many others who have generously offered help and components along the way.

Had a big disappointment yesterday when after starting the engine the entire contents of the header tank were pumped straight into the exhaust pipe. Cracked block, cracked head or head gasket; nothing trivial. The engine builder will have to sort it out but, working to a June deadline, that engine will not be taking us to France. Fortunately I do have a serviceable 1300 which I'll transfer over the weekend. Meanwhile I've made a bit more progress with the assembly of the fittings including putting in a rather poor looking seat. I have another pair of seats that I'll re-upholster at the end. Meanwhile this pair will do a turn.


John Bonnett - 3/5/15 at 07:45 AM

Well, I've got the bonnet back and it is over to me to finish it. First thing I've tackled is the the air intake aperture. To aid trimming trev sent me a picture of a clever little tool he has made to mark an offset with the scribed line on the outside of the panel. It took less than half an hour to make and it made the trimming really easy.

On the lower part of the hoop, I had to add some metal. This was done by using a TIG lap joint. I wasn't looking forward to this job but it went okay and the joint is all but invisible.



John Bonnett - 18/5/15 at 06:24 PM

Much to my relief, I've finished the bonnet without ruining it. This involved fitting additional tubes to support the front valence, wrapping the aluminium around the tubes, clenching at the scuttle end and wiring the wheel arches. I also formed the bonnet catch recesses directly into the bonnet rather than welding in the ones that I had made separately.

The lights are now fitted and the bonnet loom made and connected to the main loom. It was a very good feeling to connect the battery and see that everything worked as it should.

The windscreen and headlining are now fitted as well.

Today I've made a start on the inner wings. The list of things to do to finish the car is getting quite short now.









rdodger - 18/5/15 at 07:10 PM

Amazing work as usual John.

It looks fantastic!

Thank you. We are nearly there now and I'm really looking forward to seeing it roll out of the workshop and getting a distance view rather than just close ups.

The door skins are underway and before fitting we have the opportunity of adjusting the shells to give a nice fit and good shut lines. I've pretty much made the inner wings which although they will do the job they are intended for, are totally out of keeping with the rest of the car. They need to be double curvature, not straight line folds so they'll have to go once we get back from France when I'll have time to make a buck and do the job properly.

Another job I've got to do is to machine some thin wheel spacers; 5mm thick. MWS tell you to shorten the wheel studs so that the wire wheels go back on their seats but if I do this I cannot fit bolt on wheels should I ever want to. The aluminium plate has arrived and doing a bit of machining will make a pleasant change from bodywork.



John Bonnett - 29/5/15 at 08:16 PM

A few more pictures follow. The interior is now in and finished although the seats have yet to be re-upholstered; a job for when the car is being painted.

The replacement cylinder head arrived today and hopefully we'll be up and running over the weekend.

So, all going well.




John Bonnett - 2/6/15 at 03:54 AM

With the replacement head fitted I did get the engine running and actually drove the short distance down our lane from my workshop to the house. Here are a few pictures.

But the drama continues. There is a problem with one of the DCOE40s. Petrol is leaking out and it is not obvious even when stripped down where the problem is so it is going back to the engine builder who supplied the package. While it is away I may well fit a pair of SUs so that we can make the MOT booking for next week.

So to finish the car I've just got to build up the driver's door.




HowardB - 2/6/15 at 06:16 AM

That is incredible....

so impressed, a work of art


adithorp - 2/6/15 at 06:43 AM

Seems a shame to paint it.


rdodger - 2/6/15 at 07:31 AM

That looks just Amazing!

Fantastic work John.


ettore bugatti - 2/6/15 at 09:48 PM

Agree, it only need a polish not paint.

Just out of curiosity, what grade and thickness aluminium did you used?

And is it recommended to anneal the material when the final shape is achieved?

Again, it looks great.

It was made from 1.5mm thick in either NS3 alloy or pure aluminium 1050A. The only annealing was done in small areas like for example when forming the recesses for the bonnet catches or areas where quite severe stretching or shrinking was needed on the rear upper corners. But in general the panels were wheeled up without annealing.


ettore bugatti - 3/6/15 at 08:31 PM

Thanks!

I'm just re-reading N. Lockwoods' Designing and building a sports car and he seems to re-anneal a lot.


alistairolsen - 4/6/15 at 02:37 PM

Wow, not looked at this in a while, but what a job! Amazing work and an amazing looking car!


fesycresy - 4/6/15 at 02:55 PM

I wouldn't have the balls to paint it.

Simply superb.


John Bonnett - 5/6/15 at 09:03 PM

Thank you all for your very positive comments; very much appreciated. Believe me, the photos do flatter the car and hide the multitude of highs and lows in the bodywork. It really does need to be painted not just to hide the blemishes but also to make it usable throughout the year in all weathers. Nothing corrodes quicker than aluminium exposed to a salt solution.

The car is pretty much ready now for the MOT which is booked for next Tuesday. It was a pity about the problem with the DCOE40 but while i am waiting for it to be repaired the engine is running very nicely on the twin HS4s which I fortunately had on the shelf. I've had to modify the plumbing to suit and although it is not as neat as it was, I hope it is still acceptable.

The interior is now in with the driver's door being the last thing to build up.

So fingers crossed for Tuesday and the MOT.




Pojo - 6/6/15 at 07:05 AM

And thank you, everybody, for your encouragement and support.

John Bonnett - 10/6/15 at 05:08 AM

Barring any unforeseen unpleasant surprises, our trip to France, once just a dream, should be a reality. I enjoyed the build but now all i want to do is to drive the car and get some enjoyment from it.

To anyone who fancies trying their hand at metal shaping, I can assure you that anyone can do it. I didn't start until I was turned 60 and learned all I know from Ron Fournier's excellent videos. I a now nearly 73 and this is my second project; the trials car being the first.

As for the next project, I've not decided what just yet, but there definitely will be one.


SJ - 10/6/15 at 07:07 AM

As others have said, the car looks amazing and is an absolute work of art.

Badger_McLetcher - 10/6/15 at 05:03 PM

I may have dribbled slightly... that's lush!


John Bonnett - 22/6/15 at 08:09 PM

A couple of final jobs completed before we set off for France. One was to fit a towing eye and the other, to replace the tired and sagging rear spring. Had I realised that the spring was sub-standard, I would have replaced it early on in the build when fitting it would have been many times easier. But it was well worth the effort with the raised rear end and improved ride.

The trip to France is going to be a bit of a leap of faith with less than five hundred miles on the clock since the car went on the road but hopefully all will be well.

I'm pleased to report that all went well in France and that the toolbox remained unopened for the whole trip. We thoroughly enjoyed the whole experience and the wonderful reception the car received wherever we went. We were away for two weeks and covered 1300 miles door to door, much of it in 30 degree plus temperatures which the car coped with rather better than did we.

Pewe, very good to hear from you and thank you so much for your kind words.

There has to be a next project because at the moment I'm like a ship without a rudder. Having said that, the car is not quite finished because despite a lot of opinion against it has to be painted and the seats reupholstered which will be done after the Coupe Florio speed hillclimb that we are lucky enough to have an entry for, and a further three weeks in France.
http://www.lacoupeflorio.com/ This will take us to October.

But what the project will be, I haven't decided. Trouble is, I've blown a lot of money on this one and without selling it I'd struggle to get funding for a new one past management. However, I think this is a very pretty car based on an MG Y chassis. In many ways similar to an AC Ace.

[img][/img]

As soon as I make up my mind I will let you know.

regards
John


rdodger - 28/7/15 at 03:16 PM

Glad to hear the car was trouble free on your French tour John. We expected nothing less!

Now that is a pretty car and looks like a challenging build. I'm sure you are up to it though!

It would seem a shame not too.


John Bonnett - 6/9/15 at 12:06 PM

We've just returned from France having competed in the Coupe Florio hill climb in Saint Brieuc. We were really lucky to have an entry knowing that anybody can apply but at the end of the day there are only ninety places and they select just the ones they want. Sadly, a dose of food poisoning prevented my driving the final run but here is a clip of my second timed climb.

Thank you Ivan, I enjoyed it hugely. It has been twenty years since any competitive driving and what a buzz it was to get back to it. We showed a clean pair of heels to an E Type, MiniMarcos, TVR and Morgan to name just a few and with only an estimated 80bhp to play with it says a lot for the way the car handled.

I don't remember whether I have mentioned the engine woes along the way but if not that shows how well bred I am. But over the next week or so I'm going to book it in for a rolling road power run so that I have a benchmark for what the engine is producing now with the current set-up. It is then coming apart to see exactly what is wrong inside. It has always sounded like an engine that needs a rebuild rather than freshly put together for the best that money can buy. Hopefully at the end of it all I will have a decent unit that doesn't rattle, throw oil out and produces some decent power as well.

The most important thing for me is the suspension. My target has always been to achieve the sharpness of a Caterham and whilst I know this is never going to be achievable it is well on the way. The car runs in beautifully and corners absolutely flat even when under a lot of pressure. The biggest surprise was the amount of grip from the Michelin XASs; 155 R 13s. I could not unstick them even on the hairpin where a bit over oversteer would have helped. Here are a few photos of the event.




mark chandler - 6/9/15 at 04:24 PM

The car is a tribute to the builder, your next project needs to grow oily fingers and build the new engine yourself.

Having been competing in hill climbs this year it looks like the UK cannot touch the hill you have just done

Thank you Mark and good to hear from you. There is still a fair bit to do to this car before thinking about the next one. The Jury is still out on whether to paint it or not. I spoke to a lot of people over the weekend and almost without exception they said do not paint it. Problem is interfacing the steel parts like the sills, scuttle and windscreen frame etc. The amusing thing was that nobody could walk by the car without stroking it. Even the lady in the immigration kiosk at Roscoff leaned out of her hatch and stroked the bonnet; bizarre! I would certainly loose that amusement once painted.

Yes the climb was awesome; 1.7 miles long and climbing all the way after the flat out blatt along the quay. There's something quite special about racing on a closed public road. The organisation was a bit chaotic at times but overall it was a fantastic weekend that I so lucky to be a part of.

COOL!!
I just watched it to the tune of Kashmere by Led Zeppelin...


John Bonnett - 25/2/16 at 01:09 AM

It's been a while since my last update but the project has been moving on albeit slowly. It was an agonising decision but I decided to have the car painted rather than leave it as bare aluminium and the colour will be French Blue; a genuine Triumph colour. The preparation is just about complete and painting should be started very soon now.

I've ditched the wire wheels in favour of alloys on the grounds of weight saving and ease of cleaning. This will knock 34kg off the unsprung weight which is surprising and significant.

The engine has been a big disappointment for reasons that I'm not going in to but it has just been rebuilt and ready to collect from the builder. I did have a power run done on a rolling road before it came out of the car so it will be interesting to see how it compares with the new spec on the same rolling road.



HowardB - 25/2/16 at 07:12 AM

it is going to be a beautiful sight,.. can't wait to see more pictures


nick205 - 25/2/16 at 08:59 AM

Hi John,

Really impressed with your work on this, it looks a labour of love for sure!


John Bonnett - 27/2/16 at 06:27 PM

Thanks Chaps, all moving along well now. Please don't be fooled, It's not me doing the preparation or the painting. I've left that to the expert and all is progressing very well. He is hoping to have the colour on this week so more pictures when that happens.

The newly rebuilt engine is ready for me to pick up so everything is coming together nicely.

Thank you all for your interest.

John


mark chandler - 27/2/16 at 07:16 PM

I,m sure it will look wonderful when done.

Bare aluminium does not weather well so this was expected


02GF74 - 6/3/16 at 08:33 AM

NO!!!!!! Why!!!!

Raw alloy body and wires made it look special, now it will look like some blue car.

Its your car and you had good reasons but imo it was better unpainted..... plus youll adda couple of kg in weight.

Re engine, is it on twin SUs, 1 1/2? Is easy to convert to twin 1 3/4,

Re engine, is it on twin SUs, 1 1/2? Is easy to convert to twin 1 3/4,





Why? Okay, here goes. First of all it was a very difficult decision and I anguished for months over whether to paint or not for the very reasons you mention. However, my panel work was not good enough to polish and the steel to aluminium interfaces in some places looked unfinished. I do use my cars in all weathers and nothing corrodes more quickly that aluminium in a salt solution. Against that, the car in its ally state looked what it was; hand built, and absolutely nobody could resist stroking it as they walked by. Even the lady in the passport control kiosk at Roscoff leaned out of the hatch to stroke it. That will never happen again because it will as you say look just like a painted classic car. The decision was not an easy one but I finally came down on the side of painting because I knew that the bodyshop could improve shut and panel gaps and take the car to another level. And this they have done. I am absolutely delighted with the result, I love the colour and I'm really looking forward to getting it all put back together. I've made a good start already.

The engine has been rebuilt to a high spec which includes a fully gas flowed, big valve cylinder head and a 244 profile cam. 11.4:1 compression, bespoke forged pistons and a pair of brand new Weber DCOE40s. The builder is going to run it in on his rolling road and I'll report the comparative figures between what it produced before and now.

The wire wheels have gone and have been replaced by Minilites with a net saving of 34kg. I shall be replacing the window glass with polycarbonate and the cast iron rear wishbones for aluminium ones. Paint and filler will have taken their toll but the above weight savings will, I hope bring the car in at under 800kg.

Paul, you are a knock out. I love your humour. Very good to hear from you and I hope all is well. I fear a drive up to North Essex may be a step too far but all being well we'll be at the Silverstone Classic. It would be so good to meet up and if Saint Trev could join us my cup would truly runneth over

If it were up to Trev's standard I probably would have polished it but there really were a lot of flaws; hammer marks, highs and lows all of which would have leapt out at you had it been polished. I'm very pleased with how it looks painted and this undoubtedly was the right decision.

Once it's all back together I'll have to wheel up a pair of patterns for the perspex headlamp covers. Unfortunately they are not an off the shelf item and will have to be made specially.

[Edited on 7/3/16 by John Bonnett]


John Bonnett - 15/3/16 at 07:53 PM

I may have said that I'm replacing the chrome wire wheels with Minilites in the interest of weight saving and ease of cleaning. Unfortunately the standard wheel studs are too short for the alloys and so they must be changed. I'm using the opportunity to go over to the much stronger M12 Freelander studs. The fronts are easy enough to change but the back is a bit more fiddly. Either the hub has to come off or make a hole in the back plate and feed the stud in that way. For the time being I'm ignoring that little problem and getting on with the rebuild. Today saw the engine go in which was a major step forward. I'm hopeful of having the car running by the end of the weekend.


John Bonnett - 11/5/16 at 07:17 PM

Just to finish off this thread, I would like to thank each and everyone of you who have helped me with encouragement and advice along the way. It has been very much appreciated and a great help.

The car is now finished and I have to say that I am absolutely delighted with the result and well worth all the blood sweat and tears lavished on it. I shall be using it during the Summer after which I will put it up for sale to fund the next project.

Here are a few pictures.

It has come out a lot better than I could have hoped for and it is a shame that I've got to sell it. But I need a project more than I need the Triumph and the next one is not going to be cheap. There are a number of much cheaper options but having had thoughts on this particular one I can think of nothing else.

That,s an enormous amount of work to move on John, good luck with the new project when the time comes.

I thought about flogging my locost a couple of years ago to raise funds, I could not bring myself to do it but then the value is low so it was not a compelling argument.

I need to get a decent price to be able to start but I have absolutely no idea what mine might fetch because there is nothing to compare it with; not like a Sebring Sprite replica for example which seem to go for 25k plus. But that's in the future. there's the Summer ahead and plenty of enjoyment to be had.
