[Robotgroup] Building a vacuum forming machine need a goodvaccum pump

[Leslie Filip]

I bought it mail order and assembled it myself but the pump alone is  
regularly on the surplus market for around $90. Mine is 110v, but  
here is a similar 220v model with the specs:

If the link gets mangled just go to surpluscenter.com and search on  
vacuum pump. You would still need a timer/controller but I'm sure  
you're more than capable of fabricating one. You could use my  
existing setup for developing your table and then buy your own if you  
liked it. Personally I would not use a venturi.

Regal is currently the best source for plastics if you are judging by  
both customer service and price.
