Vacuum Forming Machine Plans
About Clamping
Remember that the sheet size is not the entire usable area of
the piece, you really end up loosing an inch off of each side
for the clamping and sealing margins
About the pump
You can save money by buying a particular air-compressor rather
than an expensive vacuum-pump.
Once upon a time you could get the Coleman Powermate (stock
number CP0070010), which had a threaded inlet port. This
means you can use it as a compressor or a vacuum pump. It also
worked great as a small shop compressor or a high quality air-brush
compressor. It's also very quiet compared to other compressors
of comparable size and pulls more vacuum than most industrial
vacuum pumps for a fraction of the cost.
Try to find your plastic locally
The last way to save money is to buy your own plastic locally.
High Density Polystyrene is usually the least expensive and easiest
to get. You may also want to check on Flame-resistant plastics
as well as the ability to recycle them. Recycling will save you
money, but be forewarned, many plastics are not taken by most
recyclers.
