| It should certainly make the job easier once you sort it all out

hey sly,
Did you ever find out anything on the missing side mechanics from the 3D model? vertigo

Oh, I had kind of forgotten about that. I've been obsessed with finding a better CAD/CAM program. I have tested about 20! In the end, I think what I had to start with is as good as any.
So.......... I re cut the model body more accurately and re-ran the middle two sections. The results came out MUCH better this time.
Now I just need to glue the layers together. 
The only problem I had was the small top piece on the passenger's side came free of the clamp during milling and caused it to be cut a little short as you can see in the pictures. But I can re-run that piece easy enough. You can even see the small grooves that decorate the car. I tried to enhance them a little on the drivers side as you can see but I think running one of those wheel things you use to set window screen wire will work best to deepen those groves in the foam.
Now I'm starting to think how to use these to produce molds. Ideally it would be best for strength to do the whole thing as one big mold, but you would need a crane to separate the body from the mold and I would be a major problem to store it any where. I have to go look at the pictures of the '89 molds and see how they did it.

| There is a lot of information on line for reinforced plastic resin boats. Might find some information there.

hey sly,
Any progress on your milling of foam? vertigo

Update:
Finished milling the front section of the body. One thing that's hard to see in these photos is that even the little decorative grooves are there.
Put the 1:24 scale Mobius model on top for a little scale perspective.
This is a little more than one third of the body. The next level will begin the cabin section and will include the front wind screen. Unfortunately, I start my yearly banishment to a south pacific desert island at the end of this month. Will be out of action 'till the middle of August. Hopefully I can have the next section milled before I go.
I have been researching how to prepare the foam plug for fiberglassing. Fiberglass resin will melt foam if it comes in direct contact. There is an epoxy resin that will work, but I haven't had much luck with the epoxy stuff, it takes forever to cure. Also need some kind of filler and some kind of sealant. The consensus on sealing is to use white glue. The one thing I've found about a filler suggests is spackling compound. I may test that out and see how it works.

Very impressive work and quite wicked.
How many milling hours did it take to produce what you have completed?

That's one thing that surprised me, the panels take a lot longer to mill than I thought they would. Some took several hours. And, as you can see, there are several panels sandwiched together to make one section. The above pictures are eight separate sections. So that's a lot of individual panels.
The nice thing is I can set it up, start it, then go do something else while it runs. It doesn't require much supervision.

nice progress sly! I've seen on smaller scale you can wrap the foam in clear packing tape as the protective layer... that may not be feasible here though. But maybe a related product can help. So large plastic wrap will have a hard time with wrinkling issues... but maybe doing a full vinyl wrap on the finished foam model, where you can warm it and apply it exactly to the detail work, will result in a good reusable mold base, to at least get a few good pulls.
Plus for at least a first static build you could wrap it in a realistic metallic gunmetal finish, with the windows done in a mirrored black or something.
