The schematic - yup, though I'd be interested in the 1c1/1c2 arrangement - these are contactors?, what actuates these? a mechanical forward/stop/reverse switch? in which case this can be re-used - which is what I think you're after?
The other thing is to look to see if you can only energise the start coil whilst the run coil is energised - again, can be done with the 1c1/1c2 arrangement, depending on it's behaviour.

My bad - 1C1/1C2 are the relays shown at the bottom of the schematic?
Then use two pairs of the 1c1/1c2 contacts to provide the change-over for the start coil, and the remaining contact for both 1c1 and 1c2 wired in parallel to provide the live supply to the motor run coil.Last edited by Doddy; 15-10-2018 at 04:46 PM.

Yes, 1c1 and 1c2 are the fwd/rev contactors operated by microswitches which are in turn operated by the motor control lever on the carriage. See bottom of schematic. Obviously they are never both closed!
You're right, I can use the third pair of contacts to switch the run coil on/off, which I haven't shown in my sketch.
Cheers!

You'll have to wait and see, you don't have the rubber mounts normally associated with single phase machines, they help significantly in smoothing out the bumps in the torque output.
I noticed a significant improvement in surface finish when I converted my Myford Super 7 to 3 phase, I would never go back to single phase for a lathe or mill,

NickYou think that's too expensive? You're not a Model Engineer are you? :D
