    What did you order? It's not clear from the website what's what. They list a "Cam Screw", a "Cam" and a "Cam Stud", all with the same photo...

    Some comments on DC Control Panel Coils -- round- vs. square-dial; 115V vs 230V

    Round- vs. Square-Dial DC Control Panels

    The vast majority of 10EE DC Control panels fall into two basic types: most motor/generator (MG) drive round-dials used a panel based on Struthers-Dunn...

    Note that Bill's DC Panel is the newer version, typical of square-dial MG and WiaD machine, which uses Cutler-Hammer 598 forward/reverse relays. (This is the type of panel with the three resistors in...

    I had a chat with Bill W (hitandmiss) on Tuesday and he made several good suggestions:

    You need to verify that the spindle motor field windings are intact.
    You should pull and inspect the...

    Sorry, I meant F2 to E2. 106 VDC is low, but that's to be expected with a simple rectifier in place of the exciter. So the field has voltage, which is what we need to see. What we need to figure out...

    The commutator in the photo that I posted had been recently reconditioned, normally they aren't bright, shiny copper like that. The dark brown or bronze color of a well circulated penny is good. It...

    I agree with labeeman and I'm 99% sure that this is a replacement for a failed exciter on a motor/generator 10EE. The transformer in the upper left probably steps the incoming AC sufficiently that it...

    Your problem has nothing to do with not having exciter voltage, which is why I moved it to a new thread.

    You can get brushes from Monarch (link). At last report, they were reasonably priced....

    Does Bijur actually call this type of part a "check valve"? I would call this a pressure relief valve, since it's job is to bleed off excess pressure. In my world, a check valve only lets fluid flow...

    For what it's worth, years back, Scott at Monarch told me that the want to see 15 PSI at the apron manifold test port. You're obviously not going to get that with a 5 PSI pressure relief valve. The...

    If memory serves, that's not a metering valve, like the rest of the Bijur fittings in the system, but a 15 PSI pressure relief valve. It keeps the rest of the system at 15 PSI and lets the excess oil...

    You might have a look for manuals on Vintage Machinery (link). There are also dozens of brochures going all the way back into the 1920's, most of which were posted by Keith Rucker.

    Thanks for the photo.

    I'm glad to see that the Dymo label makers that work with heat-shrink tubing have come down in price and that there are now third-party labels available. About 15 years ago,...

    Interesting. Round-dials have an elaborate spring-loaded gizmo that holds the rear cover in place and allows for easy removal.

    Are you using socket head cap screws to hold the cover to the cross-slide?

    That all looks nice, with one problem: white and green wires should not be used for general purpose connections; they have special meanings in standard AC wiring practice. Green wires should only be...

    I would go for it. You can't really get hurt at that price. The machine has some nice features, like ELSR, taper and an accumulating cross-feed dial. Worst comes to worst, you could part it out and...

    There shouldn't be any arcing coming from the generator's brushes. All you should see is a tiny spark at each brush. You may have a brush timing issue. This photo shows the brush ring for the...

    Good point. He has an inline-exciter motor/generator (MG). I don't actually know what was ultimately decided for the original exciter voltage. But for sure, if he has a 115 VDC DC control panel and...
