    Default 1946 10ee

    I just picked it up a few weeks ago, I talked to the last two people to operate it and they could not answer, so, any idea what this box is /and does?

    Cant help you with what it actually is. But the machine is 70 years old. When I was looking at machines I saw one early round dial with a similar box in the back - had zero effect on anything. I did not investigate further, I suspect it was not even hooked to anything when I was looking at it - that particular machine would not spin above about 500rpm and the owner at the time was fine with that......

    Open it up and take a picture of what's actually inside, also not if it is actually hooked to the current electricals (if they are functional).

    Is the field exciter in the machine? With the steps it looks like something perhaps to power the field.

    Mine is a 46 and there is nothing like it on the machine.

    All the parts are there and the machine was operational when it was disconnected in Nov 2015 I was thinking it was a Potentiometer for additional control but I am not sure. The hard conduit for the wiring makes me think it's factory installed.

    I was noticing you have what looks like a transformer mounted above the motor. My lathe does not have that either. My fused disconnect is mounted in the spot where the box is on your lathe. Could it be the main power connect point?

    From the knob, it is probably attached to another rheostat, used to set the reverse speed when using the leadscrew reverse.
    The numbers by the pointer are probably spindle speed, since the tach only works in forward.

    Post a pic of the open box to solve the mystery.

    The machine came well documented.

    One more of the gizmo on the back of the machine.

    Googling around this is the only reference I can find.

    Boy this is a long shot, those electronics look amazing like the Keller Tracer attachment that my Monarch has. It could just be that they are very close in time period. I wonder if any 10 ee came with tracers?..............

    A friend mentioned tracer last night as a possibility, I don't see it listed as an option in the manual, but then again I don't see potentiometer (or whatever it is) mentioned.

    looks similar to the rheostat that controls the forward speed (chain driven one onside the base), so my guess is its for adjustable reverse speed as others have said.

    Post a picture of the front of the machine - does it have ELSR?
    Congrats on the documentation - looks like you even have the original monarch inspection sheet for the machine. This may mean you have more detail in the schematic blueprints. Your going to want to post pictures of the schematic prints, these could help.

    Electronics/electrical are not my area of expertise, but as you have probably gathered plenty of knowledgeable people on here.

    Yes ELSR. The front.

    Nice - looks like you have an accumulator readout on the carriage handwheel - I believe these are quite rare.

    The black knob on the box at the back of your 46 Monarch
    is like the one on my machine of the same year. A cleaver
    device for sure. You can use this feature when cutting
    threads. First you have to properly set all the knobs and
    levers for threading. Now the fun begins. Engage the half
    nuts and when you reach the end of your cut back out the
    tool and raise the lever that reverses the spindle leaving
    the half nuts engaged. The spindle reversing speed can be
    adjusted via the that black knob which also reverses the
    speed of the lead screw. So the saddle can rapid back to
    the starting point. Set the compound screw stop and zero,
    with the little knob on the side and this makes for some
    quick threading without needing to watch the thread dial.
    For long threads still use the dial as usually done.

    Spaeth's confirmation is that it is the variable speed option for the ELSR feature.

    If you don't know what ELSR is yet - search on it here. Bunch of mechanisms that turn off the spindle when it hits a stop. Allows accurate threading to a fraction of a turn of the spindle. The variable reverse lets you have a faster reverse speed so you can get back to the start quicker.
