Is there anyone in the group that has any experience or information they can share regarding a 1940 Monarch 18-BB or CBB? I just purchase on and need to get it home. Looks to be in amazing shape. This lathe is fitted with a 440v 3ph motor and I weighing the options of changing the motor to a 240v. Also looking to see pictures of others lathes.

Thanks in advance!

The motor may possibly be dual voltage, but the problem may be with the magnetic contactor, where the coils would likely need to be changed to the lower voltage, but perhaps the solution might be to use a boost transformer and keep the control circuit on high volts.
I had a Monarch 12" CK in my shop that I sold, it was a pleasure to use! Another possibility would be to use a drum switch instead of the magnetic starter, that is what I did on my 19" Regal LeBlond at my home shop.

Yes, that is the one! I saw one just like that about 25 or so years ago at a dealer's in Berkeley, but it was no cherry.

I wired my 14" AA Monarch directly to a VFD and eliminated any other switches . There is a reverse button on the VFD.
The good VFD's have good directions on wiring.

My Monarch is very similar to yours. Built in 1939.

I'm glad you posted. I was thinking whether that was possible and as I tought about it, the lathe is all mechanical control, so its a matter of getting power to the motor.

Thanks!
