And you can get a VFD that runs on 120v up to 1/2 hp.

A 1/2 hp 3-ph motor will be cheap on eBay.

Hey, thanks... I don't have 3ph in my shop though. Will the VFD's w/
220 1ph-in/220 3ph-out work in this situation? Or, are rotary phase
converters the only option w/ machine tools? In that case, I'd just
scrap the thing and buy a full-size Bridgeport anyhow.

Sure, they'll work. - GWE
