    Delta 7” bench grinder 23-105 repair questions

    Yeah, that makes total sense, and was what I was originally going to do. I read something somewhere suggesting that because it was using a centrifugal switch and start winding instead of a capacitor for starting that it was safer for the motor to switch both. Nonsense? My understanding of...

    Delta 7” bench grinder 23-105 repair questions

    Mine has had the neutral switched as well. I was planning to still do that, since it was apparently part of the original design. Would I then need a three pole to do this?

    Delta 7” bench grinder 23-105 repair questions

    Definitely interested--I'd love to run it that way. If it is easier, and you can find someone else with pictures online, a link would work too. I'll take a look at that too, thanks.

    Delta 7” bench grinder 23-105 repair questions

    Definitely upgrading to LED. Having the little incandescent bulbs was great when it was new, but they really don't put out much light. As for the separate switch, unfortunately I don't have the pedestal with the grinder. And my bottom plate doesn't have a hole for the wiring to pass through, but...

    Delta 7” bench grinder 23-105 repair questions

    Yes, the mass of wires in the center are the wires that go up to the motor through a hole in the base. Is it OK to interrupt both the white and the black? That is how it is currently set up, and I know that it was done historically, but is it safer/better to change that so that only the black...

    Delta 7” bench grinder 23-105 repair questions

    Electrical questions will likely continue, but I also have some more general questions. As I'm cleaning the grinder up, I'm realizing it has several layers of peeling paint built up. I want to take that down, at least some, and probably repaint at least well enough to protect it from rust. I am...

    Delta 7” bench grinder 23-105 repair questions

    Thanks. I didn't mean the electrical part of it--I've got 120 up at the end of the cable where it enters the "twin lite" unit, and the connections to get that right up to the lampholder are easy enough, and there's plenty of room for them. I meant I wasn't sure about how the actual lamp holder...

    Delta 7” bench grinder 23-105 repair questions

    If anybody knows anything about these, let me know. It almost looks like they’re insert and solder, except the bad one is the only one I can actually see solder on. First pick is a bad one, last pic is of one that works

    Delta 7” bench grinder 23-105 repair questions

    I do have a meter. The left unit is working, but the right is a mess--I get weird measuments that make no sense to me. I read 115v at the point where the wires come into the housing. Nothing at the pins. One pin has no continuity with any of the wires except right on the back of the fixture. The...

    Delta 7” bench grinder 23-105 repair questions

    Thanks, and I had my terminology mixed up. I HAVE a double throw switch. The parts list mentions a "2 pole toggle switch." Should I assume that the 2 pole toggle switch was there to allow for wiring the grinder for 240, and that in some retrofit/repair, someone used a 2 throw instead of a 2...

    Delta 7” bench grinder 23-105 repair questions

    A few years ago I came into possession of an old Delta grinder. The original pedestal is gone, but it came with an adequate stand. Anyway, it has a double pole throw switch: center is off, right is on, and left is, well, left has been nothing. Still, it worked for what I needed and so I sent...

    Replacement 12v test light for OTC 3633

    It finally struck me (I’m slow sometimes) if the 3636 and 3633 use the same size bulbs, even if the 3636 IS led, I’d I put an incandescent bulb in, it becomes what I want (minus the needle point and threads). Right? Is there any circuitry in the device itself, or is it just straight wired? Same...

    Replacement 12v test light for OTC 3633

    I’m pretty sure they are describing the 3633 (which is discontinued) and you linked the 3636. Which I’m now leaning against since it is LED.

    Replacement 12v test light for OTC 3633

    Thanks. Does anyone know if there’s a good quality alternative that *does* have the threaded fine point?
