Probably a treadmill motor but it does well for me. Surpluscenter
recommends adding a fan for cooling at low speed but so far I havent
seen enough heat to warrant it.

I'm planning on mounting the motor where the original is and usining a
length of flexible dryer duct from the end of the motor to under the
bench where I'll mount a computer fan. This will provide cooling and
keep chips out of the motor.

The twiddling and modifying has no end it seems

Yeah but it's fun! :-)
