Rim Drive Mod or how to make it even better

Its interesting you mention this. I have my SAMA placed on a 6 x 6 slate tile and isolated from the maple platform using Sorbothane feet. I am also using silk thread belt for the Super Platter. The plinth rests on footer so both the SAMA and plinth are at the same relative height. I prefer this setup over having both the SAMA and plinth resting on the maple platform.

I ordered my rim drive in February and still don't have it! Who do you know?

Can't wait to try all this stuff...

Harry W... I had to wait as well. The wait is worth it. You get to open up the motor assembly and see a rats nest full of wire. You must cut and reattach the wires. MAKE SURE YOU"RE CUTTING THE CORRECT ONES. Oh - here's something I remember as well. You have to take the 4 silver feet off of the assembly. Peel the green felt pads off - they are only stuck on with glue. Put them carefully onto some wax paper or something similar to save them. When you finish the project, it will run (I forgot) very slow or very fast. Adjust with the SDS. Put the felt pads under the feet as I suggested above. Get the felt pads from Home Depot - furniture slides. This will enable the whole assembly to slide easily so that you can just kiss the drive wheel to the platter. Be sure that the wheel is driving on solid metal. Adjust the height so that the wheel is not running in one of the grooves of the platter. If you have a VPI arm, at first the drive will make the arm dance uncontrollably. Don't be socked - just wait 2 days for the belt around the drive wheel to seat. Enjoy.

Tom, if you are impatient and dying to try RIM drive on your VPI it is alot of fun to DIY with an old platter+ bearing . I don't know if it is better or not than the stock upgrade, but it works very well and surely much less expensive !

I finally got my rim drive yesterday. I hooked it up, and tried it out. Right now, I have 2 problems:

1) Speed stability. The KAB speedstrobe shows that the table is not running smoothly. Just by visual inspection I can tell that this speed instability results from the belt on the rim drive. It does not form a perfect circle. It other words, the belt has a few "bulges" which cause the contact pressure with the platter to increase, thereby briefly speeding it up. How does one address this?

2) I cannot currently use the Periphery ring clamp because it contacts the rim drive. To accomodate the ring clamp I would need to raise the table about 1/2 inch. If you loosen the Scoutmaster feet enough to raise the table 1/2 inch, the table itself will no longer be stable, but will be "wobbly" instead. What to do?

Thanks.
