AMi K-100 tonearm mystery

Okay, here's a little picture puzzle. Those of you who are familiar
with the AMi mech circa 1960 should be able to answer this pretty
easily.

I'm resurrecting an AMi "K" that was kind of a basket case, and I
believe it is missing a part (or parts) in the tonearm assembly. The
problem is that the tonearm assembly does not sit down securely on the
pivot post, so instead of pivoting smoothly left and right, it wobbles
around drunkenly. Check out these pictures:

It sure seems like I'm missing a bushing of some kind, but I don't
have mech to compare it to. I have a manual for the "J", which has the
same mech, but in true AMi style it contains NO diagrams or part
numbers for this assembly.

And yes, I've picked up all of the various small parts from the bottom
of the cabinet, and found nothing even close.

So what am I missing?

You are missing a brass bushing that sets on the pivot and goes up into the
tonearm. WURCO reproduced them and I bought out there remaining stock years
ago. I only have one left but could part with it for $40. Let me know if you
are interested.

If someone is interested, I have a freind with a machine shop, and a
machine, that once programed and set up, would whip them out one after
another. We could possibly put this part back into the "available"
status. I don't know if there is much of a call for it or not? And of
course, I'd need one good one to start with.

I decided to go ahead and buy the one from Glenn. I am considering
taking it to a local guy here who I know has done similar machine
work, and get a few copies made. If he can't do it, I may get in touch
with you.

I'd at least like to have a spare or two for myself. I doubt there are
many AMi's of this vintage left that are worth restoring, so not many
people are likely to be missing one, but who knows. And I'm assuming
they do wear out eventually. Why else would this have been made as a
removeable part?

I think you need a ball bearing as well, I got mine from Stanmann in
Germany, its a brass bush but inside it has a ball bearing to act as a
bearing!!

Hmmm... I haven't actually seen the bushing yet so I can only guess
how this works. I'm guessing the bushing sits on the pivot post, the
bearing goes down inside of it from the top, and the tonearm assembly
sits on top of the bearing.

Did you buy the bearing separately from the bushing? If so, do you
know what size the bearing is?

Hello Mr. Willoughby,
it's a 3/16" steel ball inside that bushing. We have a picture of that
little assembly on our website. If you search for the part no. A 013
or "tonearm bearing assembly" you can have a look.
