i'm going to start manufacturing of bodyshell, but slabside or fia ?

I see now Russ, thanks!
The door should go a little farther back on the model, to the edge of the fender. On the one photo taken from above, there is a little bit of body between the fender and door.
Don't get me wrong though, it's not a big deal.

Dang-it! You're absolutely right. Now that I look at it more closely, the rear fender flares aren't big enough either, and the front edge of the hood scoop doesn't have the proper curvature. In addition, the gumball placement on the nose is incorrect.

That's it, I'm putting an M80 in this thing.

HaHaHa!
Sorry Russ, didn't mean to blow it for you! It's still pretty cool!

Hi Simon,
I'm using now meshlab (http://meshlab.sourceforge.net/) for cleaning of STL data and development version of rhino3d osx (http://www.irhino3d.com) for orientation of math data.
As soon as i've done with all corrections, i'll use CATIA for class A surface work and 5 axis CNC milling of model.
Regards,
Ozgur

Ozgur...I was planning a trip to the moon, could you throw together some plans for a rocket for me? you know...on your spare time...

Hi joey,
Hah hah, That's very funny. You made my day !
The thing is even jaguar xj-220 started as pet project of engineers from Coventry, UK.

Great project, please keep us informed! I'd love to see some pictures of the milling process.

Hi,
i'm still working on the orientation of 3d model based on some reference dimensions.

It has been long time since i've sent some update about project
I'm ready to start bodyshell from Scratch
I've decited to go classic woodenbuck way to built model.

I'm working on hardtop with integrated a-pillar & windscreen a la factory five '33 hotrod

Ozgur,

Do you mean something integrated like the AC Mamba????

[Ozgur_Tan]

G'day John
Yes similar to mamba (but removable)
i'm not sure for fastback style
i'll follow dragonsnake style hardtop with integrated windscreen and a-pillar
and
for summer wraparound lexan or single racing windscreen
Regards
Ozgur

[John McMahon]

Hmmm...what about a LeMans hardtop like on this here Kirkham? That would be cool....

[Ozgur_Tan]

Here is the some pictures of my work in progress wooden buck

[John McMahon]

Ozgur,

Very cool....what software are you using to create this?

I seem to recall that you have produced a number of cool images using various products...very talented!

you remember 100% about different applications that i've used
couple of my posts that contains screenshots disappear because of server problem of clubcobra.com some time ago
i'll add those missing pictures asap

Looks like you are doing a similar project like I do (if I understood right).

I made first wooden/foam (polyurethane) buck and finally pull a mold out of that (not completly ready yet).

I spent a lot of time trying to make that plug surface perfect and that is a nightmare if you have wood/foam plug like I have.

My main problem was that no matter how nice surface you make that wood sections will be visble after few days. Wood and foam just act differently in different temperature/moisture etc.

If I started now all over again I would add few layer of glass mat after rough finish of foam. That could made that plug more solid so that there is allways same material under filler.

If you like to know more about my project send me a mail.

There is also some pictures about my plug/mold in my callery.

[Ozgur_Tan]

as you can see on the updated pictures of my buck
i make sections as -18 mm offset from outside surface
than cover with 18 mm plywood strips
to archive good surface quality

ps:
i would like to double check outside diameter of front headlight bezel, can you assist me ?

regards

G'day jberg
My initial plan was to use 5axis cnc to mill epoxyputty and make model/mould, same as we do for motoryacht and automotive projects.
But, i would like to go with sections that will be cnc cut.
Good luck with your project
Regards
Ozgur @ istanbul

[Ozgur_Tan]

G'day to all,
I would like to give an update about project
next week wooden sections will be cut using CNC machine
Bodyshell and hardtop material will be carbonfiber w/ vinyl ester (or w/ epoxy)
opening panels will be aluminium (doors, hood, trunk)
I'm gonna post some pictures soon
Regards
Ozgur

Hi Ozgur

Nice to see that your project is on track.

Have you some idea how thick these mold wall's should be? Or what is your opininon that should these molds be rock solid or have some flexibility?

I have about 5 layers of 450g shopped matt, plus one layer 600g rowing matt (top layer) plus some "stiffering beam's" near of parting lines. I just don't know is this enought but I know that this is not even near of rock solid yet.


BTW. Good day at least here in north. All roads are frozen in mornings and my car go side way in every corner. It could be "interesting" drive a cobra these days here...
