I have forgotten who posted earlier but they referred to a book "The Prop Builders Molding and Casting Handbook" by Thurston James. I bought the book from Amazon.com (it was not expensive like the techie stuff) and read it. Only the last chapter deals with vacuum forming and that on a grand scale. Like making tile roofs for movie sets. Very interesting though. The earlier parts of the book renewed my interest in fiberglass casting so I have been off on that tangent lately. BTW, the hard parts of vacuum forming seem to be the matter of an oven big enough for the work and creating a vacuum source (or is it sink?) with enough volume to draw down the material before the material cools out of the plastic condition... A home vacuum cleaner arrangement is not really up to the task. Besides, my earlier experiments with home vacuums lead me to believe a lot of air FLOW is essential to avoid toasting the motors.
