    There is a drawing, but it's in really rough shape, sections are missing and some parts are illegible. It does show the area in question. What is shown is a setscrew, spring and plunger. The same...

    Brian,

    It's from a square-dial DC control panel with a Cutler-Hammer bulletin 598 contactor:

    I don't like using thread cutting taps and dies to chase threads. It's too easy to damage the threads. I've got a set of thread repair taps, dies and files that are perfect for this sort of thing....

    It's been a long time since I messed with it, but I think I replaced the washer on the screw end with one that has a smaller OD, so it still holds the felt disk, but won't hit the feed gear.

    That looks just fine. But you need to drop the apron a bit for the washer to clear the cross-feed drive gear in the apron when you insert the screw.

    On newer round-dials with the lever-type gearbox (instead of the T-handle) the gearbox outputs can be disengaged via the lever.

    What do you mean "lower knob"?

    The 10EE feed-rod worm gear (part EE-2106) is the same for most round- and square-dials, with the possible exception of the Sundstrand drive machines. Square-dial parts sheet 147 shows the worm,...

    The worm sump on my 1943 10EE has a tapped hole with a plug. As far as I know, all 10EEs are like that. I've always thought that the sump was intended to fill to the level of the feed rod and any...

    Very nice work! You really should add a nice brass plate somewhere with something like: "Loving Restored by Grant, 2021".

    Nice lacing job!

    FYI, Using white (or green) wire for anything that's above ground potential is bad practice. Slip a couple of inches of red, blue, black (or anything other than white or green)...

    The only time that it pumps when threading is when the carriage is moving. Even if the feed-rod is turning, the pump cam isn't operating when the feed-direction plunger is in the center (threading)...

    Download the 1965 square-dial manual. Parts Sheet 115 shows the tailstock. All the 13xx and 14xx part numbers are common to round-dials and the rest are similar.

    I'm pretty sure that the apron pump also works if the feed-rod is turning and the feed-direction plunger is pulled out. (The way the apron gear train is drawn it's hard to see how the gears mesh, but...
