Ralph, . *Lots of 8" lathes *are 7" lathes with a 1/2 inch rise on the spindle axis. I'm working on 1/2" risers, maybe even 1" risers to get to 9", but it really wont be a 9" in strength and

??? Ralph how do those motor bearings feel , How did the motor sound was there any whining on the brush side ? ??? I'm kinda thinking? that ya may also have a bearing on it's way out . I'm

Ralph, That is a massive misalignment! Is that glued in place or is that some kind of sealer, or did it deform from running hot! . You're on track for something! Send us a photo of the whole

The gaps just need to be below the copper. Realistically, anything that will get them there will work - toothpicks, small screwdriver, blunt scribe, etc. Cheap and/or old toothbrushes are handy for

Commutator cleaned up nicely. Looks pretty flat, doesn’t seem worn. I didn’t expect it to be, our little lathes really don’t get enough use for that to happen. Unlike something like a car

Oops, here is the rough comutator! ( https://photos.app.goo.gl/Xbbm2DZUPaofjkkz8 )

I have the motor off the lathe and have cleaned up the comutator, which I have a bunch of question. But thought I show the brush holder first. As you can see the brush holder has gotten hot and is

What's needed is a saw blade that fits neatly in the gap between commutator segments - on larger motors, a hacksaw blade is appropriate. On these smaller motors, an X-Acto razor saw blade is the right

As with everything, there are differances. Those are from small armature to huge ones. So any method to clean out the insulation, mica, would vary in size and method. I mentioned hacksaw blade

As far as I can tell the difference is dependent on the manufacturers idea on what & how their tool is supposed to function . I can't find a picture of the second one I mentioned with the hacksaw

Ralph, Truly any thing that gets the job done with the lease amount of damage, is the "correct" tool. . You need to clean the gap, then lower the material in the gap to below the surface of the

Handsaw blade will be fine. You want something with a bit of width to scrape out the junk. Hacksaw is pretty blunt compared to a knife and less like to cause any damage. Anything that you can

RE: " It has a short piece of hacksaw blade mounted for cleaning out the slots" I thought someone had said it was not a good idea to use a hacksaw blade. I know the Armature lathes have a rotating

I have another armature lathe , that I bought 20=30 years back . Had no idea what it was , I have a weakness for things that seem bitchin & much to my wife's dismay I have way to many . It has a short

You can do a pretty good job by just using a strip of abrasive paper in a shoe-shine motion with the armature held in a vise or clamped to something convenient. I did quite a few motors that way

Here's a pretty comprehensive guide to actually available belts & pulleys: < https://sdp-si.com/tools/download-papers.php > Roy

You do NOT need to remove the timing belt from the lathe , just from the motor pulley. You may need to remove the lead screw to remove the nuts that hold the motor to the lathe bed. You should not

Thanks for the help. I will have to clear a space to dismantle the lathe for further inspection. That will not be easy! Ralph [email protected]> wrote:

The holders should be fixed firmly to the end cap, and lined up directly to the one on the other side. The brush should have just enough clearance to slide in & out, but not wobble about. I think
