I have been looking for a suitable vacuum pump for my CNC machine for a while. I do have a small 2-piston high vacuum oil-less pump similar to this one, but the air flow is not that great:

So I thought a Supercharger from the scrappy may do the job and found the one below eBay for $59 (Eaton M62 for a Buick 3.8 V6, free shipping :) ).
Received it today and it is in pretty good shape. The plan is to power it with a 1 or 2 hp induction motor and pulleys to make 6000 rpm. According to the chart from Eaton it should pump about 500 m^3/hr or 300 cubic ft/min at that speed.
Did anybody try this before? I mean I will find out soon but it would be nice to know before I go to Harborfreight to shell out another $150 for the motor. Thanks.....
