Homemade vacuum forming

I started learning vacuum forming because I desired to build a metal detector coil housing (the cover of a metal detector search coil). Basically, vacuum forming is the process of forming a plastic sheet into a usable part through vacuum between the plastic sheet and a form. Many house items we use are made by this technique. I used the following items: - pieces of wood to build a frame to hold the plastic sheet - screws - 2mm polystyrene plastic sheet - homemade form of the piece to be replicated, made of plywood - vacuum table (a homemade wooden box with many holes on top and a vacuum output tube) - vacuum cleaner (mine has 1400w) - oven (electric is better but mine was a gas oven) Below you can see some pictures of the parts used: Some important tips: - the wood form should be covered with epoxy or something that prevents the plastic from sticking to it. - Keep the plastic inside the oven until the center of it it reaches more or lesse 150 degrees...
