right now I don't have a reversing switch on my treadmill motor.
I didn't either. Getting the single speed motor (which was installed
sometime around 1950) to run backwards was one of the challenges in
adding metric to my lathe. I still want to switch to 3 phase with a VFD
(and maybe an electronic lead screw add-on) but for now, I got some
many-conductor cable and ran all the connections for the starter coil in
the motor back to the barrel switch, so depending on which way I turn
the motor on, the starter is wired up in forwards or reverse, and the
motor starts that way. You have to wait for it to come to a complete
stop before changing directions, but it was a cheap fix.
