Are the front wheel arches large enough to to steer, they look a bit small.
Also the scuttle looks a bit odd (not clean enough)
Otherwise a smart looking car!

Chassis work looks great.
My opinion on the body....You have smooth flowing edges everywhere, except for the front radiator opening that is a square frame. I think it might
look even better if you soften the corners of the front opening.

You can do it quickly. You can do it cheap. You can do it right. – Pick any two.

Thanks for the comments chaps.
Del- Yeah V5 is pretty pricey but then even 3k for Solidworks is out of the reach of most of us. Your modelling approach sounds similar to mine. Chuck
it on the screen, then try to do it properly.
Ceebmoj- I was looking at constructing the front end in a similar way to the rear (all sheet steel) but it was getting very complex and heavy. It
worked out much easier and lighter to keep the diagonal tubes for the front. As for learning TIG, I guess a few months really. Although my ally
welding still leaves a lot to be desired but I've not done much of that. I've tried a few different TIG plants but am using a Rehemann now
and am really pleased with it. Its a INV200 AC/DC and was only about £400. I've got a much more expensive transformer based plant as well but
the inverter is easier to use.
Ettore- yeah front wheels just about clear, I think the perspective makes it look tighter than it is. I'm not happy with the scuttle either-
especially as in plan view it looks like the car is wearing a bra 
Fred- I see what you mean, its a bit out of place. I wasn'y too keen on that bit myself but I tried a few rounded versions and it all looked a
bit soft. I wanted it to be a bit more aggressive. I've got a few other ideas for the front so will post the pics when I get round to modelling
it up.
Cheers

I first saw Catia back in 1990 when it was being used on Harrier GR7. I've never actually got the chance to use it unfortunately though.
Surfacing in itself is clearly an art, and one that I've not yet even begun to get to grips with properly.
The car looks great BTW, though I think you are in the same boat as me to a certain extent on being able to properly express the ideas you have in
your head on the body V what you can get into the 3D model.
I also preferred the previous (Black) version better.

Just a thought - has anybody out there tried any of the yacht design packages for 3d body shaping as that's basically what they're all
about.

Apparently many of the yacht builders use Solidworks or Catia!
Doug - have you ever dissected a finished article made by a pro? It's about as intuitive as sticking your hand in a vat of molten iron. I joined
a few groups and several were kind enough to send out files I could backward engineer - even having those to hand it barely made sense! About the only
thing that became apparent was there was no way they could have created a lot of the surfaces with a finished article purely in their mind, which is
what lead me to the blocking method - once you have something existing on the computer it's a great deal easier to see how you can make sweeping
surfaces to start with and intersect them later.
Of course none of that helps with the fact that you'll suddenly get 101 "failed due to geometry conditions" messages unless you are
merely duplicating what others have produced and can figure out why by comparison!

Nope I've not got to that stage yet, once I've got the software choice done then I'll just bang heads with it until it gives in.
I was look at a tutorial on how to do an Audi TT the guy said it would take 100 hours to complete properly

100 hours.... I've spent 3 bloody years on mine...

Nice project Bob, I like your Black renderings best.....
Do you have other views of your renderings ?
Cheers

Nothing much I'm afraid.
I've got most of my pannelling done. Covered my internal panels with Carbon/Kevlar and laminated it to the ally. Some pics are
here (on page 2).
I've also done some more design work on the bodywork and got something that I'm pretty happy with.
I bought a better lathe recently as well so have been trying to get my wishbones made, but havn't had much time.
I've redesigned my front uprights to be stronger and a bit lighter, so should get those made soon.
The trouble I have is that everthing is being designed from scratch (except engine and g/box) so it takes time to design, then earn the money to pay
for the bits, then make the bits, then do it all again because it's not right.
In the mean time I'm trying to figure out how the hell I'm going to mold the bodywork . . I think I've got a plan for that now
though.
I'll get there in the end, I hope.
Cheers
Rob

Hi bob,
I've been following ur progress for a while and think your frame design is spot on. I dont think that your body design compliments all that hard
work though. try slanting the front a bit forward and not so "seven-ish". Sorry for the criticism but i think u have a fantastic frame and
that front section is not too flattering.needs more work.

Don't worry about the criticism. All comments are welcome.
The front has been the hardest part to design (of the body that is) and I'm actually quite pleased with how it looks, finally. The front slants
back as I wanted to make it look more aggressive, but I do kind of see your point about it being slightly sevenesque.
I think if others agree with you and don't like it, I'll have another go, but at the moment I still like it.
Your comments are appreciated good or bad.
Cheers
Rob

pardon me
Hey Bob,
Sometimes I simply wash everything out into a soft wash to help identify the basic panel shapes before I begin to shape the different areas in
aluminum. I took the liberty of doing that with your dark blue rendering and came up with the left illustration. There were some areas that I
wasn't exactly sure what you had planned, but for the most part I think you can see more clearly the different planes of the car using this
method.
The second unit is just a different take on the front end. I'm not sure but that I like the original one better but this may give you an
alternative or a start on a new design for the front.
I really like your project build and am confident that whatever direction you choose it will be a knock-out!

It seems to me that in the body designs shown above there is not enough room for the front wheels to steer, unless those wheels are very narrow. The
problem seems to be at the back of the front wheel arches.

i quite like the convex-concave knifed out look, kinda hints at BMW style, looks great. I would open up the grill/ airscoop area a bit wider, to make
it look more aggressive.

Dick,
Thanks for that, I like that effect- how did you do it?
Gakes,
I have tried to add some BMW style flame edging, and will be adding some intakes in the front for brake cooling. Also there will of course be a
splitter which I think will add a bit of aggression.
Cheers chaps,
Rob

The scuttle is looking tight, I like it.
Not sure about grille and 'bumper' though.

Hi,
Nothing terribley exciting I'm afraid- been CADding mostly.
Most effort has been on the uprights re-redesign. This is done now so I just need to get the drawings done for the laser profiling and the bearing
housing turning.
They use Sierra rear hubs front and rear but with the drive flange turned off for the front ones
Front Upright
 
Front Suspension
Rear Upright
Rear Suspension
I have also had a go at designing my own hubs but decided in the end to stay with the sierra ones for the time being despite the weight of them.
I did manage to get my steering column made though as well, so I've been doing a little bit of sitting in the car turning the wheel and making
engine and tyre squeal noises
Cheers,
Rob

What material and thickness are you using for the uprights?
And did you do some FEM analysis on them already?
Good to see progress!

Uprights are 3mm mild steel and I have stressed them already.

Update
Hi,
I've not updated for a while so thought I'd take a few pics of where I've got to:
Rear Suspension is now mostly complete
The calipers are Hispec Ultralite 4 pot, discs are Ford Mondeo front discs 300mm dia.
Hubs are Ford Granada so the discs had to be redrilled as the PCD was different.
Also, I fitted the pedal box:
Front suspension is almost done, I just need to make the uprights.
Once I've got the car off the build table onto its wheels I plan to remove the engine from the RX7 turbo donor to rebuild it.
Cheers
Rob

looks good do you have any other picks of your pedal box it looks cool with the initials on the pedals
