VPI Rim Drive vibrations


I have VPI SSM with RIM drive and SDS. The issue I'm having is a vibration being transferred from rim to the desk/platter. As the result tonarm wobbles a little bit in azimuth plane.
I tried to replace the brownish rim belt, change contact force/distance between the drive and the platter, and reinstall the belt - the vibration still there (exactly one wobble per rim's full revolution - 360 degrees).

The speed stability is very good though - have checked it with KAB Speed Strobe.

Any ideas how to resolve the issue?

Thanks a lot!

Krell303....as for MY SS/rim drive, I got all of #1 and none of #2. Maybe it's my Bearpaws maybe trolls, but I'm a happy vinyl guy. Just thinking as I write. My floor is very solid French travertine tile at ground level with no basement. The turntable sits on a very solid table on a very solid floor. Anyway, its working well.

Normansizemore...VPI arms sit on a needle point, and the rocking can be very obvious with the rim drive. Most arms have gimbled bearings which would prevent the rocking I discribe. I suspect Thorens, Duals, Garrards, Miracords, etc. wouldn't have this problem even if the drive wheel were elliptical.
I have the Super Scoutmaster Reference with Rimdrive and Edensound Bearpaws. I get absolutely NO rocking of the tonearm- it is totally rock steady from the point the tonearm is lowered onto the record to the end of the record. I used the Fozgometer to adjust azimuth. This has completely eliminated any wobble I used to get when I adjusted azimuth without this device.
Stringreen...I have hardwood floor in my listening room and the basement under it. Both do not make a sound foundation for the table. Before SSM I had VPI Scout wall mounted on Target shelf - no issues with vibration whatsoever. Unfortunately SSM with Rim drive is just too big and heavy for the Target shelf.

Now I put back original feet and running the table non-stop for 24 hrs trying to sit the rim's o-ring belt more/less evenly
Krell303...Running the table for 10 years won't help it. you need Bearpaws or something similar to eliminate the wobble. If you have wooden floors, I would make sure that the table that the VPI rests on is very solid...that's about all you can do. I am quite sure that would be enough.

I spoke to Symposium Acoustics (they are located not so far away from me in NJ) and have decided to try Symposium Acoustics Ultra Platform shelf – put it on the set of three Roller Blocks Jr on top of my rack. Ultra Platform supposed (hopefully) mto eliminate microphonic effect introduced by hard pointed TerraCones and at the same time to eliminate lateral vibrations from floor.
To be continued.
