I am currently in the process of building my first vacuforming machine, just a small and simple machine to be run with a toaster oven and shopvac. Next version will be bigger and with built-in heating elements.

but anyways, as i'm still a newbie i have a couple basic questions...
i will be forming lexan/polycarbonate rc car bodies, and using hdpe from milk jugs for test runs. do either of these plastics give off bad fumes when melted? (google couldn't help me here)

another thing, where is a good/cheap/reliable place to get polycarb from?
