Thanks for your help, that worked great. I had another idea though. I kind of like the drum handle size/placement on my bench to turn the lathe on/off.Often the thermal switch IS feeding both the run and start circuits. Is there a diagram you haven't posted yet?
My assumption looks to be correct: the red and black wires are only the start winding not the entire start leg.
So you may have to disassemble the motor to figure out how the start leg is configured and the thermal protector wiring. It can be a pain.
My advice: use the second switch for power and the drum for direction only:
Extend the red and black wires and connect them to drum switch 3 and 4. Connect drum switch 1 and 5 back to the motor terminals where red and black came from. Drum 2 and 6 not connected. Connect your second switch in series with the hot line wire to the motor. Done.
If I would keep my incoming power on drum 2/6 and 1/5 back to the motor, I would have an on/off/on at the
drum.
Then use a DPDT toggle to control direction.
From what I’ve read the toggle wiring would be:
Extend red/black start wires out to 2 center terminals
Connect 4 outboard terminals using a X pattern
Connect 2 wires back to motor from either outboard end of switch
I could do this with a 4 wire cord
Does this sound like it would work?
