Re: Vacuum Forming --- Was--->Lights and lenses, the poor mans laser?

Graham,

I have been wanting to try some vacuum forming for a while now. Can
you give me a quick rundown on the process? I am planning to make a
molded cover for the back of my machine (the one on the home page).

I know I need a vacuum source - I assume a shop vac would be fine. I
know I need a heat source - your idea is very neat.

What types of plastics can you use and where can you purchase them?

Are there any guidlines as to the mold - number/size of holes finish
needed to keep plastic from sticking etc.?

Thanks

Chris
