Yeah, Tim, you are right. Make that 40 ufd or so. BTW, there's a nomograph
in Elect. Handbooks that specifies start cap sizes.

I think you can forget the resistor. Run it straight, after starting.

First I tried it with 40 ohms and it spun up very slowly after hand
starting. So that told me, safely that's the run winding.

The name plate says it is a 2.5A, 700 RPM single-phase motor, so
what's to worry?

Might hit a short somehow. The lights dim nicely when I stall the drill
press, granted it's a 1/4HP motor. But it has a centrifugal switch to
turn
off the start motor.

In all likelihood the
odd terminal is for switching in a start capacitor - which probably
resided in the host equipment. Try a 140 - 200 uFd cap from either
side of line, momentary, for starting.

Sounds like an awful lot for a 1/8HP motor, I'll have to string up all the
oil caps I have in the house to test that. What kind of switches can I
get
to turn off the start winding after it's running?
