I'm at wit's end.
I've successfully made several clear canopies using my old Mattel VacuForm or the "plug and push" method, but I can't seem to produce a decent canopy for Emil Zarkov's OV-10 Bronco.
As a single piece, the canopy is too big for my Vacuform and for plug&push.
I tried cutting the pieces of the canopy out of flat stock but shaping it is difficult and the frames are too narrow to hold the sections if they are not perfectly shaped. Heating the transparency film and forming it just left me with a mess.
I thought about molding it in sections (sides, top, windscreen) but the frames are so narrow that I don't know if I'll be able to join the sections securely.
I've also thought about doing it in two pieces--front and back halves--but I don't know if that's going to work either.
I have been using epoxy putty for the molds but when I make a mold this large, it's hard to work the putty enough so it doesn't crumble or crack when it cures. Is there another mold material that might work better?
Emil, or anyone else out there who has built this very fine kit . . . HELP!
