Replacing the Motor on the Boxford AUD

My Boxford Aud died this week. I took the motor out this afternoon to get the details for a replacement.
It is currently a three phase using a 0.75HP Brooks Gryphen motor.
Looking at their website it looks as though I can find a nice new replacement at about £75-00 very easily.
Before I picked up the phone I thought I would just ask the question "Should I take this opportunity to convert to a single phase?".
I expect I could find a single phase of the correct power and size to fit BUT....
Does anyone know what wiring problems I would face.
Is it a good idea or am I being stupid.
(It would save plugging the lathe through a phase convertor)

I have a Boxford AUD wired for 1 phase. I'll get some details and pictures tomorrow ( Thursday) and probably send you a PM.

I've just moved on from a single phase CUD, if I kept it I was planning 3 phase.
I think you'll find reversible single phase more than the 3 phase motor. Also you won't have the speed control.
The finish is meant to be better with 3 phase as well.!!

Compared with 3-phase, single-phase motors vibrate more, provide less torque, and are unreliable. The only good reason for using a single-phase motor is lack of a 3-phase supply. As you own a phase converter it makes no sense to change to single phase, especially as the lathe would have to be rewired. Spending time and money on a complicated backward step wouldn't appeal to me.
If money is no object you might consider upgrading the phase converter to a VFD . The combination of VFD and 3-phase is hard to beat - speed control and other improvements.

3 phase every time! The ability to control the speed without swapping belts and pulleys alone makes it an easy decision.

3 phase with vfd would be the preferred choice
