Tiny vacuum pump

Does anybody have an idea on how to make a tiny little vacuum pump on the order

110, but I can rig up a 12 volt supply if necessary.



If you have a compressor, use a venturi vacuum generator.
Harbor freight has them for about $10 from time to time.

Jim,

That air compressor sprayer I gave you a couple of years ago is just a
venturi. Use the liquid imput end to generate the vacuum. Unless ypu lost
it, you already have what you need.
