    Monarch still offers new lathes at around 150k all options. However, from what I understand they re-use later style circulating headstock castings.
    This new Japanese lathe would likely top 100k.

    I saw the motor, being a dual mount type its certainly not original, 3600rpm, perhaps the source of your hum, high speed AC motors not so good for heavy starting loads like lathes.

    Looks like a nice machine, has the later improvements, circulating oil in the headstock, and heavy tailstock.

    I have cut lots of acme threads, awhile back I made some changeable arbors for an old table saw, the thread pitch was 12. That is getting pretty fine for an acme thread, but sometimes found on...

    Bed wear is a hard thing to deal with, and has a big effect on the value, or usefulness of the machine. On lathes with really long carriages, the wear near the chuck has less effect on causing taper...

    Though differently laid out, the Reeves drive system in the Rivett has much of the same mechanical aspects of the drive system in the Moore jigborer of the same time period. I have not come across...

    If you have done alot of work with die grinders, the electric models are much larger, generally do not work for long at low speeds. I am hoping that some of the new electric motor technology finds...

    It looks like the price of older shovelheads and panheads is going up some, evo models not so much.

    You dont need a phase converter at all, the machine will run on 220v single phase, the only 3 phase motoer would be the coolant pump, and it looks like you dont have one.

    I believe your problem is part 57, and its mating part #20 "I think", those parts are the clutch for direct belt drive. Those parts can get pounded from too hard fly cutting.

    Yes, see if the machine runs at a single speed with the module removed, and check the module diodes, bad ones can point to the problem circuit.
