I thought someone might know how to use a wood/styrofoam mold (is that properly called a "buck"?) to fabricate a superbird type nose for my '72 Plymouth Sebring Plus "Super Satellite" project car (search "Project Odyssey" on this site). My question is how to size it, i think the model mold would have to be slightly smaller to account for the metal that is formed over the top of it, but how much smaller would it need to be? Or am i wrong and the mold/form can be the exact size of the finished project? I have a very detailed fabrication book but it seems to skip right over my problem/question. Thanks for any hints you might be able to offer.
