You are correct, Michael. I have a vacuum pump and a larger two-stage commercial vacuum former, but making my own was a lot more fun. I'm working on a full description of the process on my web site. You can watch it develop at http://twofootartist.com/vacuum-forming/ Many vacuum formers use a box with a perforated top, which requires evacuation of a relatively large volume of air. Mine uses a solid shelf with an airtight perimeter that evacuates in a split second using my 1963 Electrolux vacuum cleaner. -Wes Ewell

You need to evacuate the air fast and I don't think you need to draw it down to anywhere near what the vacuum pump is capable of doing. Keep the vacuum pump, though, you are going to want it when you start casting parts with silicone molds. -Michael Eldridge -Current project: remodeling a room for guess what --- In mailto:S-Scale%40yahoogroups.com, "ctxmf74" <ctxm@...> wrote: > > Where would you learn to do something like that? > > > > I just bought a vacuum pump to do some AC repairs but have no idea how to > > use it for modeling. > > hi Carey, I don't know the details of using it but I know vacuum forming > can be a way to get cars built.
