Ok got the parts table out, what is the trick to removing the collar nut safley? ...
Remove the headshell, if any, then move the tonearm toward the platter center. This will expose the left side bearing of the tonearm gimbal.
Jeweler's screw drivers work nicely. First rotate the inner screw, counter-clockwise, until its slot lines up with the slot in the collar. Then, with a wider jeweler's screwdriver (wide enough to bridge from one side of the collar slot to the other, through the inner screw), rotate the two together, in the counterclockwise direction. Once the collar is free, you can gently rotate it off of the inner screw (counterclockwise). Then screw the inner screw back in, just until it touches, and back off 1/8 turn. That will keep the tonearm properly suspended and the remaining bearing parts safe.
Tim, you are a lifesaver. csmith (the table owner) will carry on negotiations with you, for trades or price, via private conversation. He will give you my address to ship it. Please do not ship it in a simple envelope. The letter handling machine will cause the parts to tear out and be lost. You can fit the collar into a hole in some cardboard, then into an envelope. That will make it safe.
We found the rubber hole plug. You can keep yours with your parts unit.
This will make csmith's table complete and ready for successful restoration. I will post a couple of nice pics, when done, to show you what you contributed to.
Thanks in advance,
