Vacuum Chucks, Fixtures, and Clamping: Definitive Guide .

Interesting thought: to pull a vacuum, the compressor must overcome a pressure differential of 14.7 lbs per square inch. To compress to normal shop air pressures, it needs 10x that much pressure differential. Doing duty as a vacuum pump is much easier on the compressor. Geoff suggests a 2HP converted to vacuum pump is plenty.
