I'm looking for a decent vacuum regulator. I've found decently vacuum pumps at reasonable prices, and I'm going to build my own vacuum tanks: http://www.joewoodworker.com/veneering/whybuild.htm
But now I'm looking for an electro-mechanical valve that will cut off the pump when the vacuum hits about 25" Hg. Any ideas? I started trying to find a good regulator, but the only regulators I'm finding are really expensive at over $200, and that doesn't include a cutoff valve to shut the pump down when the pressure gets high enough:
Maybe it's cheaper in the end to just buy a more expensive regulated pump? I don't know.
