I bought a little Barker horizontal mill last week. It's the AM model, and in great condition. The trouble is it's 3-phase. Simple to change out the motor, but am I better off getting a new single phase motor, or going with a static phase converter, or VFD?. Cheapest new motors I've found are about $200.00 for a 1 1/2HP. Original motor is 2hp. I've got outlets for both 110V & 220v where this is going to go. Any advice greatly appreciated.
