Back in college, on a limited budget, I cut the soft plastic liquor bottle cap, one of the soft gold ones. Worked perfectly, and still working to this day! And it created its own dimple.

PL-41
Thanks to all of you who have contributed to this posting. I used the information to service the bearing on my PL-41. I used 1/8 in sheet Delrin stock instead of the Delrin rod. I cut out a little square of the material, nibbled off the corners and inserted it into the cup. My bearing had two of the spacer washers; I scrapped them since the 1/8 sheet raised the platter to the correct height. After running the table for less than 15 minutes, the dimple appeared in the Delrin. I see no need to machine in a deeper dimple.
My table still needs work however. After running for 5 minutes, the motor exibits a ticking noise....about 8 times/second. I have taken the bearings apart, cleaned and re-lubed with Singer Sewing Machine oil and bicycle chain oil. The problem still remains. Do you all have any ideas on what could cause the motor ticking noise?

I don't think that is usually a good sign. My PL-41 is disassembled. Let me know if you need a replacement motor.

Motor tickjng
IIRC the "speed change" lever from 33 1/3 to 45 can rub against the belt, so check this is in the correct position
Check the rubber grommets that hold the motor; as these can fail
Check you've got the correct length belt

Resurrecting an old thread:
What about using a delrin guitar pick cut to shape for a thrustplate. It's much cheaper, easier to find, and comes in thicknesses of up to 2mm (slightly thinner than the .083", but close).
Any opinions?

If I am remembering the thing correctly, that seems far too thin. It is certainly easy enough to have a shop part the right thickness off of a rod.

delrin guitar pick
Dear jeeves:
The guitar pick is much thinner than the original thrust plate. I do however think it will work provided you shim to get closer to the original thickness. If you don't get close the the right thickness, the spindle will ride too low in the sleeve. You can give it a try because you don't have much to loose. More spacers may cause more problems. On one of my earlier rebuilds, the spacers would turn inside the cup and the sound was audible. I now tack the delrin (no more spacers) down with black RTV.
Most posts on this topic do mention Delrin as the material of choice but as djkieras points out, the original material was much softer than Delrin, some think it was nylon.
Dear pajanda1;
Thank you for offering up a motor. I did find a PL-50 motor for this table that worked with just a few changes to the mount.......and just two weeks ago another PL-41 motor in very good condition.
