    I could only guess as to what the machine was, so I googled it, and found a couple of pics of yours that I hadn't seen before.
    ???

    That's a lot of warrs there, so there must be several motors on this thing?

    Power knee for sure?
    Have you tried the switch for that?

    Is there any other "independant motor" controlled movements?

    Maybe an oil pump(s)?
    Machine lube and coolant?

    The buzz will normally go away soon if you run it much.

    Ok after I posted that I sort of had a eureka moment.

    This thing has a main drive motor, feed/rapid motor, and coolant motor. No lube pump I can see/know of.

    The motor starters aren't really show in the picture of video, but they are massive things. I've got two, one for forward and one for reverse.

    Then the starter with the red arrow on the bottom left, must run the knee motor. I heard a faint mechanical whirring noise from the machine when that starter energized. That's one of the reasons I stopped messing with the machine, the knee dosent have any oil in it right now.

    The starter next to that must run the coolant pump, I can see the small wire from the coolant switch going to the coil.

    I'm still confused with the top things are. The one with the arrow on the top left and two things next to it.

    Yah, well, the starters are all 1950's vintage.

    Ok since I'm sort of oriented a little bit better now, I'll try it again and maybe get it going.

    The breaker in the machine has a label of '53 and the machine was built either '53 or '54

    The inside looks the same as my 3CH. Did you use a motor rotation meter before putting power to it? Don’t ask me how I know but my 3CH will make all kinds of noise if I try starting it backwards.

    Idk if the start up sequence is the same for your mill?
    Push the master start and hear a slight hum. Push the handle forward and the spindle starts, push the handle forward again and the feed/elevation motor starts up. You’ll know it’s running because the feed shaft on the right side of the knee will be spinning.

    It says but date is November (dont exactly remeber the month) of 1972.

    And I highly doubt there are many of these in the states, since its originally Chinese built. But presumably a copy of a British or Russian machine.

    A picture of the tag is in the old thread about this machine. But its date of manufacture is kinda irrelevant to getting the motors turning.

    Those toggle switches would work, but this machine is 440V only, there were rated to 380v.

    Late to the party, One of my past trips to China, I toured a plant where they had a exact copy of a Cincinnati Hypro planer, about a 20 foot capacity. Instead of Cinn-Hypro up on the over head on the columns, was Chinese writing. All of the controls were in Chinese, too. Couldn't take pictures or I would have been shot!

    American Pacemaker is coming togeather. Took $50 worth of new bearings, but seems to be silky smooth now.

    Just need a motor starter and to free up the tailstock.
