Seconded on the 3 phase motor and vfd
This is the setup I use on my boxford BUD cnc conversion
A one horse power motor is more than enough
I still have the pulley options but rarely change it from the middle pulley
The motor is set up for 50% over speed
So I can get upto 2000 rpm at the headstock
And back gear is available if I need silly amounts of torque
Motor came with the lathe and is a brooks motor. I changed the jumpers to delta wind
The vfd is a £50 Chinese affair but other than the dinglish manual it’s been fine for two years

Cheers. Paul
