??? Mine is identical to the one I linked . I've seen them on
ebay & at some flea markets . the motor has that long skinny
shaft with a little star washer kinda lookin cutter that cleans
out the grooves on the communicator .? Let me see if I can find a
longer youtube on it . Mine is over at a bud's place , We were
thinkin on doing some automotive alternator windmills , but life
got in the way . I installed some new power in our local NAPA auto
parts for their new alternator tester? when he said gimme a bill I
told him I wanted the old tester , we were gearing up & then
.....
Here's a pretty good tube on one , these folks have a couple of
the l'll buggers .
Ebay has a couple but their pretty darn proud of them .
this ones pretty good , Lost Creek Machine had one a ways back
they may still ?

Mike,?
.
I have never seen one of these and
this unit clearly has a label identifying its'-self.
Is this your actual lathe or similar
to yours?
What does the motor do? Help with
balancing? Missing a chuck that has a cutter to clear the
grooves between the armature contacts?
Does it have a main drive motor?
.
Nice history lesson.

I picked up a armature lathe many years back at a yard sale .
I asked the guy how much for te armature lathe & he said "
is that what that is " . He gave it to me cause I was the only
guy out of 50-75 people that knew what it was . Have used it a
fair amount over the years .

If ya ever see one of these at a yard sale & ya can get
it cheap their on the handy side .
I've always used scotch pads instead of sand paper over teh
years , their a bit cleaner then sand paper . Here's some

You don’t need to
turn it, you just need to clean it.

By turn I meant put
it in the chuck and spin it by hand, holding? the
sandpaper in the other.

Here’s some good
pictures showing the general idea: ,
obviously a smaller motor than what you’ve got.

“kinda rough” is an
understatement.? Basically that carbon can build up
between the copper rails and cause a short, might be
your problem.? But yeah, shiny & smooth is good.?
Once you get all the black gunk off you be able to see
if there any further damage that you’ll need a lathe to
fix, things like gouges & pitting.

What do you mean by
belt?

My other lathe is not running so I
cannot turn the commutator.
That commutator does look kinda rough.
What is the belt?
