at the side of the box is a tube (simple nylon male connector at the hardware store) to connect to a vacuum cleaner(for suction) then you put the part you want to mold on top of the holes, making sure there is releif angle, lay a piece of the plastic over it, heat with a quartz space heater till it droops over your part, the vacuum will suck it around tight...outside the plasticsheet the holes can be blocked with paper..that is it very basically..
Thats it..made some canopies for model airplanes that way..of course those were small parts but the principle is the same..

On a related note, has anyone thought about vacuum bags? This would apply more to laminating wood veneer to something like an instrument panel, glove box door, armrest, or a console insert, but I think once a person got started using this technique, the possibilities for the technique could come flooding in.

Here are a few links for your perusal. While they deal mainly with woodworking, with the exception of Chris Fouquet, who discusses making model airplane wings, the basic idea remains the same.

http://www.pilotsguide.com/rc/vacbag.shtml

http://www.woodweb.com/knowledge_bas...wer_Faces.html

http://www.joewoodworker.com/veneeri...uumforming.htm

Personally, I think the last link explains the process a bit better than the others, but that's just me. Chris Fouquet (the airplane guy) brings up the idea of laying up fiberglass and vacuum forming it over the mold as well. The possibilities there seem endless.

I'm thinking those "Spacebags" you see at Wal-Mart and other places could be used for smaller pieces, and Chris Fouquet has a great idea for making bags for larger items on the page linked above.

Just a thought…

Try wooden boat magazine for info on the vacuum bagging.. those guys make some huge wood veneer laminations with the vacumm bagging process..Heavens a fellow could make an entire car body with that process if so inclined..actually it is quite simple to do..
