Part's

The belt is easy...  Get an O ring at Ace Hardware, it'll work better and lasts much longer than the original belt.

Danko 35747B at Ace Hardware, Danko O ring,stock number 35747B, #33 O-ring, 1 1/16 x 15/16 x 1/16.

I can't help you with the connecting pins, though I suspect you can create something that would work for those. I'm assuming you're talking about the spring loaded contacts that ride on the contact rings.  What happened to the original ones?

Thanks for the o-ring information, I'll be at my local Ace Hardware in the morning.

One of the original pin's is good, the other not so good.  I don't know if the spring is damaged somehow because the narrow pin that sticks out the bottom is not as long as the other pin.  I bought the turntable used and when I took it apart the pin's fell, so I didn't know how to orient them.  I'm assuming the thicker rounded end is what slides into the turntable and the thinner end is what rides on the base.

Actually, I believe you have the pins upside down.  The rounded end rides on the fixed base contact ring, the spring is stuck on the smaller end.  The pins are actually pushed down on the TT by the spring.

The fun is putting the TT top back on once you've screwed the base down and overlapped all the bays with track!  I used a little grease to hold the pins in the TT top until it was in place, that seems to work, at least for me.

Yeah, after my last post I was thinking I probably had them in upside down.  Thanks

Now I just have to find at least one new pin.

You can probably make one out of a brass rod and just round the end and polish it.

OTOH, it's possible that they are different lengths.  I remember puzzling over them when they fell out of mine.  Look closely at the bottom of the table and check them, you may not need any replacements.
