I just bought a new pile of vacuum pumps - mostly dual wobble piston, all
110VAC - I'll update my web site to show them after posting this note - I've tested them all, two are in need of work - so if you want a really good price and are willing to do some work, I will sell the ones needing work for $25 total (postage included within the USA) each. One of them has stiff bearings, one of them makes a clicking sound, neither draw a useful vacuum. They are both Thomas brand, dual wobble piston, 1/3 hp. The broken ones are, of course AS IS. The tested and working ones of course cost more -- see my web site below.If nobody snaps up the two that need work, I'll fix them eventually, but this is a way for someone with time on their hands to save a few $$
