    I've been using PPS for some months now and agree it really is nice for cleanup on the harder to clean products. The integrated filter is lovely for paint at risk of inclusions (like old enamel). One...

    Hey, use whatever brings you joy. I just thought the properties of this might make it a good choice for machine paint.
    I've previously used the KM equivalent to the "super spec" and apart from the...

    I used some of my fancy aircraft anti-chafe paint yesterday, looks light tool-gray to me, which is fine.
    Solvent base and guns *really* nicely when mixed per directions and run through a .8mm tip...

    As reported above, there is something wrong in the drive that precludes tuning. Before I solved the resistor issue I could attain the rated spindle speed and could set the minimum voltage and some...

    thread on the drive system is here:
    New to me 10EE ser39962, with drive issues (of course)
    but it has a lot of false leads and random dead-ends.

    In brief.
    Original drive system.
    Armature goes...

    Using the lathe a touch has improved matters. I got to about 1900RPM today.
    Watching the Armature it looks like 0-225V is the range. The field is 85V until 750RPM then dropping to 20V by 1900, at...

    I did get as far as pulling the tumbler and shaft. Knowing the cover comes off like that is a big help and thanks for the gasket tip!
    After having squirted some oil onto that square slide or at...

    I did try rotating the spindle while engaged, I tried released, I tried in CDE settings on the next gear. It wasn't just that it didn't shift fully, it was that it didn't budge even the slightest. ...

    DING DING DING, we have a winner, one of my 1600ohm resistors was in fact bad.
    Thanks Cal, I would have paid no more attention to a wire-wound resistor of the type than a bit of wire.
    The 1600 in...

    Not quite my problem, the problem is: things go badly when it does open. I have to prevent it from opening in order to have the contactor remain engaged. As soon as it pulls-in and opens, the...

    If you could check me here, I'd appreciate it:
    when you press the set-speed button on the ELSR control while the machine is running in forward, it stays in forward but uses the pot setting for...

    Good point, hard evidence indeed!
    I have every reason to believe the relay is just fine. It's a NC relay so if the coil were open or not consistently energized the relay would act as it does with...

    The compensation pot call-out is indeed 200K on all the schematics I own, but this one is 240K as is the one in my parts "works" drawer. No dead spots but good call on the cap. The lathe does run...

    A-B threading selector jammed

    This machine sat for a couple decades so some things work pretty reasonably and some things are quite stuck.
    This control is stuck in the B position. After some effort and gentle persuasion I was...

    How do you clean out your gun (assuming you spray it)?
  17. I appreciate the information, don't go out of...

    I appreciate the information, don't go out of your way to make a sample though. I don't have to match a particular color and I'm pretty sold on the idea so I'll buy a kit and try it out on a Monarch...

    Overkill sounds like just the right amount to me.
    Considering the alternative for me is automotive urethane with ISO-cayinate hardener, I can't imagine it's all that much worse: tyvek suit, gloves,...

    Good to hear. Do you think it would stand up well as a machine-tool paint though?
    How fussy is the application?
  20. Interesting paint option? PPG areospace anti-chafe coating. Desothane® HS CA8100

    One of the interesting things happening on the surplus scene is with Boeing being impacted by the pandemic and also not being able to build the MAX, they have lots of really neat (read expensive)...

    Indeed, thanks very much for that confirmation.
    The PO was trying to work through drive issues and had disconnected several things and then ignored the lathe for a decade or two. I've made a...

    I absolutely had no reason to believe the drive should run right with all it's been through, I was just reporting the observation as a diagnostic point of information. I did try tuning the drive but...

    ELSR speeds are reversed

    The speed control for the ELSR controls the spindle speed in forward and the main spindle speed selector governs the reverse speed. Obviously this is not right.

    Or rather I think it's the...

    So, six months is long enough to ignore this poor lathe I think.
    After having reacquainted myself with the machine I can summarize my issues thus:
    If I hold the AP relay closed, I can attain...
