Single Phase Bridgeport 1

[swall]

I am a hobby machinist and have a Series 1 Bridgeport.Yesterday, I toasted my rotary phase converter. Before I spend $500 on a new one, I'd like to look at the possibility of replacing the Bridgeport three phase motors with single phase 220v motors.Has anybody done this?

just noticed this post now, probably a little late, I would think a VFD rated for twice the three phase horse power rating for your motor would be your best bet, you will have speed control, reverse, ramp up and braking properties if needed as well as motor overload protection all in one, these go on E bay very cheap sometimes,

Uncle Syd--thanks for the links.Reading them brought back all of my nightmares from EE301! Which is why I am a metallurgist and not an EE!
