Ive got a southbend Fourteen lathe. It has the variable speed pulleys
that go to a two speed transmission.

It has a 200 volt 3phase baldor motor. Baldor say that it is rated
for +- 10% on voltage.

I am using a 5 hp idler with no caps running off of 220

If I try to start the motor in high the motor starter on the lathe
chatters before it finally stays engaged. Low speed starts fine.

But the motor gets hot after about 10 minutes of running( you cane
keep your hand on it for about 10 seconds before it gets
uncomfortable)

any recommendations of what I should do.

Thanks
Bill

Probably should not try and start anything much over 2hp with a 5hp
idler. Assuming this is not a purpose made phase converter idler
motor, you really need to check the phase currents and adjust them with
running caps. Also, make sure the power for the lathe motor control
contactor is not on the developed phase. I built a 15hp converter two
years ago and it's been working nicely, but it uses running caps to
balance the phase current.
