VPI Rim Drive vibrations

Hiendmuse, I think that the vibrations are being caused by uneven placement of the ring belt on the RIM wheel. It's almost impossible to put the belt in the wheel's groove evenly

Krell303, I don't have any issues with vibrations from the rimdrive belt or anywhere else. The 10.5i tonearm is rocksteady when playing an LP- no wobbling. I use no special care or tool when putting on rimdrive belt. Make sure there is not too much pressure from the rimdrive belt against the platter. When turning off motor the platter should turn approx. 1 turn before stopping completely.

Hiendmuse, looks like I'm putting rimdrive too close to the table - it stops almoust instantly. But - do not have any tonarm wobbles anymore. Will try to reajust over the weekend, thanks!

Krell, I put a small red sticky dot on the side of the center clamp. you can also put one on the side of the platter to count the number of revolutions. You do NOT want the tonearm to wobble which is GOOD. Do not adjust so the tonearm wobbles, adjust it so the platter stops after about 1 revolution or slightly more. It only takes minute changes in moving motor. Make sure motor is centered front and back between the side of the table and the gap between motor and side of table is equidistant. Your vibration problems should go away.

I've only just come to this exchange - so you may all have gone away by now...
I've read it all because it addresses many of the problems I've had with rim drive - and I'll try the suggestions, particularly Stringreen, Thanks.
One thing I don't understand. Various people have put various things under the motor assembly. It isn't clear if they bypass the stock feet and rest them on the underside of the motor casing or not. I can only raise the motor assembly a very tiny amount before the rim drive is so high it prevents my using the ring clamp.
What am I not understanding ?

Hello...... Anyone still there......
