    Hi Nick,

    Can you post photos of the back end of your cross-slide, so I can see what you've got left. I need to see what draw bar you have and how the cross-feed nut is attached.

    I'm pretty sure that's a serial number. At least on 10EEs, Monarch stamped the serial number of the machine on the backs of chucks and the bottoms of rests.

    Your lathe is "round-dial" 10EE and is equipped with the "electric leadscrew reverse" (ELSR) option. ELSR is really a misnomer: all the mechanism does is stop the spindle motor when the saddle bumps...

    What's serial number and build date of the machine? What type of drive did it originally have? It's hard to read the data plate, it doesn't look like that for motor/generator (MG) drive machines. In...

    The guy with the DC panel parts is still around. He's going to see what he has left. At one point he had two sets of 598 forward/reverse contactors and three field acceleration (FA) relays.

    It's entirely possible that someone replaced the ball thrust bearings with roller bearings and that accounts for the gap at the dial. Maybe someone with a square-dial will pull out theirs and measure...

    Roller thrust bearing? The ones that I've seen use ball-type thrust bearings.

    Is the backlash the same all along the screw?

    Does the gap in front of the dial change?
