Capacitor start motors are notorious for tripping GFI receptacles.
GFI receptacles are typically designated for use with portable hand held
tools, which a lathe is not.

On what do you base those statements? Where have you seen restrictions on
the type of loads that can be run from a GFCI?

It sounds like your motor incorporates a centrifigal switch which is not
opening because it is worn out or fused together, or full of crud.

That could trip a circuit breaker due to over current, but it won't trip a
GFCI circuit, as it is not a "ground fault".
