In addition to the old gearbox speed changer, speed can also be varied
with a pot (0-60 Hz).

I have a TECO FM-50 for a 2HP Bridgeport. A pot and on-off switches
in a separate box would be a lot more convenient. What are typical
specs for a potentiometer for one of these? Something I could pick up
at Radio Shack or do I need to order on line? Under what section of
the manual would you go looking for specs if it's something that
varies by manufacturer and model? I only read enough of the manual to
get my mill up and running so I could play with it. Now that I've had
it for several months, it's time to make improvements.

Radio Shack pots are garbage. Spend a few bucks and buy something
like this:

then it will last for years. I might even have one laying around
that would work. They are mil spec, and availible surplus. They are
sealed, so you don;t have to wory about dust or metal chips damaging
them.
