Greetings to all you big scale modelers!

I'm new to this forum, and generally not the forum type, but since there's a whole bunch of one-eighth fans around here,

I wanted to share my work with you. The first car I did in 1/8 was the fabulous Cheetah by Bill Thomas and Don Edmunds.

The model is curbside (no engine or chassis), with the body carved from rigid foam and the details mostly made with rapid prototyping.

She had the honor of being the first because to me, this car is sex on wheels. So, have a look...

Absolutly BEAUTIFUL !!!... The Cheeta has got to be one of my favorite cars of all time... You have done a fantastic job... B)

OK, I think I got the hang of uploading good-looking pics now.

And now, a little WIP photo series of how the Cheetah was carved. It's like magic :lol:

@ Plasticfanatic: That hollowing was a messy job. I did it after casting a mould of the body.

To get access, I cut off the roof and carved it all out.

Messy alright, and dusty too!

Thank you very much, is indeed quite a lot of work and effort, but worth every minute of it since you turn out an AMAZING model(S)....again, congratulations on a SUPERB craftmanship and scale models.

@ Cato: Nope, I'm not using RenShape. Or maybe, yes - it's hard to tell, because I have used leftovers from industrial modeling until now.

Basically, it doesn't matter what brand of KBM (Kunststoffblockmaterial - "Plastic block material") you use.

As far as I know, it's always foamed Polyurethane, and the only difference may be in the foaming process, influencing the structure a bit.

The main difference is about the density of the stuff, which is coded by the color

(but the makers may have different colors for their densities of course.)

Choosing the right density is crucial, because a light density means easiest carving, but sharp edges (e.g. fender flares) are damaged easily.

Also, the bigger the chambers in the foam structure, the bigger your problems at the filler stage are.

My observation is, that light foam produces a really heavy orange peel when fillered. You can add a thick filler and sand the peel down,

but the filler will continue to set down for months and you will see the peel again in the paintjob. It happened with the Cobra...

Heavier density foam is harder to carve, but the filler and edge issues are not as bad.

Personally, I found that density around 0,3 grams per cubic cm works best for me.

The main issues about the stuff are availability and price. I hope for you that in the US it's easier to get.

After all, it is pro material used in the rapid tooling process by industrial modelers. I found that they charge absurd prices in hobby shops for it.

I'd really like to support all you modelers out there with the know-how I've got about industrial modeling,

because the opportunities are countless. I thought about writing a book about it (like those Kalmbach how-to paperbacks),

but I'm not sure wether it would sell.

another kudos here, that is fantastic work! thanks so much for posting those in progress photos of the body. sets a totally new bar for me seeing that. incredible.
