How can I tell if it's a split phase motor?
Also, since this is a stand alone motor, I could just switch belts
between a grinder and a lathe setup.

Thanks for the information on the 1hp motor. I've got a local motor
shop that should be able to help me out.

Is there any useful purpose I can put a 1/6HP motor to?

It won't have a capacitor "hump"

A shop cooling fan.

Probably.

3/4 HP would be better suited.

If it is a split phase unit, not a good choice for a lathe.

You need what is known as a "megger" or also a "growler" to determine
if the motor has a short in the windings.

Any money spent to repair a 1HP motor is a waste of good money.

Take it to a motor shop and have them test it.

If they want anything more than $20 to look at it, toss it in the
scrap heap.
