I think with plain bearings your probably limited to 1400 or so rpm, thats why they went to rolling bearings.
If its only a 1 hp motor on the lathe it might be cheaper to just replace it with a single phase one. I keep hearing how 3 phase motors run smoother but I've never had surface finish problems with lathes that used single phase motors.

Free advice is worth exactly what you payed for it.
