how fortuitous - I was just about to post my occasional "solicitation
message" reminding the group that I exist, and here comes the perfect inquiry and an unsolcited referral - what could be better :-) I have at this moment two 1/3 hp wobble piston pumps left, one three phase GAST vane pump (with a VFD if you want it that way), and a few other vane pumps - all the info is on my web page under vacuum pumps (www.wbnoble.com). And, there is a fairly lenghty and hopefully informative article (and a much shorter summary) about the salient characteristics, how to use them, and so on - the links to the articles are on my web, and also in the tips section of www.woodturners.org And, I make inexpensive faceplates - welded ones - again the details and pricing are on my web page, but under faceplates (seems logical, no?). I started making them because I couldn't see paying $35 for a faceplate that would be used on a fixture, you too may have a similar aversion - I'm a great believer in functionality so while they are not beautiful works of art, polished to a high shine, they will hold your wood or fixture.

Hi Bill,
I have a couple of questions that you may be able to answer: 1. What happens in a typical inverter VFD drive when the wire(s) connecting the speed control pot are broken? Does the motor shut down or run away or.....? 2. I am using a 2 cylinder, single-stage, fairly large, old refrigeration piston compressor as a vacuum pump. Apparently it was used many years ago on a farm to chill a large cement tank with water that the cans of fresh milk were placed in to cool quickly. I cleaned the valves etc and it pulls about 28" Hg and seems to be able to tolerate some leakage. Any (very) rough idea how this pump compares in pumping capacity with say a real vane vac pump? Thanks, Billh "william_b_noble" wrote in message news:1107656326.e40c8eb2b60aa6270feb3e89f7a4c692@t eranews... how fortuitous - I was just about to post my occasional "solicitation message" reminding the group that I exist, and here comes the perfect inquiry and an unsolcited referral - what could be better :-) I have at this moment two 1/3 hp wobble piston pumps left, one three phase GAST vane pump (with a VFD if you want it that way), and a few other vane pumps - all the info is on my web page under vacuum pumps (www.wbnoble.com).
