you still staying in Cowtown?Looking into it, it does not appear hard to do. The vacuum former is nothing more than a plywood box, sealed on the bottom with a pegboard top and a hole in the side for a shop vac, plus an aluminum screen frame to hold the plastic. One would also need an oven to heat the plastic sheet. I shall get on with it. Moving house next month, should be able to set up a better shop in the new space.
