We have an old lathe that had a overhead drive system and were wanting to attach a gearbox and vfd 7.5 hp 3 ph motor. I had an old faye scott that was adapted that way. Any sugestions.

What RPM does it need?
I'd personally just mount another flat belt pulley on a jackshaft to drive the lathe, and use a V belt to connect the motor to the jackshaft.

why not connect it the old way , but use a vfd to control it. it sorta' worked then. if you have
control of the ac frequency , with a Dodge or whatever 3 speed truck
gearbox in control. and you can go to higher rpms, 700-800 is ok... they didn't have hss or carbide.
nobody cared. so those 400 rpm top speeds were fine then. going from lineshaft belts to hangover ac-motors
must have been a revolution. don't be afraid to go too fast . you will hear it howl if starts to detonate.
good luck.

The old flat belt drive cant take 800rpm more like 400 and it is pushing it, you need to post size of lathe and a pic or 2...Phil
