So I'm going to be using a CNC to cut all the part of my build then going right into the build full time until it's done. Part of my plan was to get all the wood parts assembled and then, seal with "the mix" then float the aluminum skin.
Since I'm using a CNC I was going to have it trim the metal to the 1/4" narrower than the body width ahead of time, plus put holes that would be tiny ovals for the trim screws to go through so if it expands it had room to move. Use some flexible sealant.
Wanted to float (see what I did there) this concept out there to see if it would be ill advised or if I'm missing something? Is 1/4" narrower not enough for expansion, I assume the trim could cover up 1/2" each side? I know many oversized and then trim. Also wanted to know if there is other things I could do to prevent oil canning?
