VPI rimdrive squeaks

Has anyone else got or had a problem with a VPI rimdrive making a regular chirruping or squeak (in time with the rim drive rotation, not the platter).
Rimdrive is on my SuperScoutmasterReference, converted from belt drive.
I've tried ensuring the contact is as light as possible but no joy.
Silence if rimdrive isn't in contact with the platter, twice per revolution squeak from (I think) contact point when rimdrive engaged.
At 45rpm squeak is audible from 3 or 4 feet away. Less at 33rpm but still there.
HELP ! This is driving me mad.

Rateourmover,

If all else fails, try oil/grease change on both platter and rim-drive spindle.

No Stringreen, I'm not using pointed solid feet. I'm using flat plates made by Symposium Acoustics, which mate beautifully to the bottom of the motor assembly above and the Symposium Ultra shelf the plates sit on below. These plates made a real improvement, and eliminates movement that the motor assembly had using the rubber feet. I tried both the original rubber feet and their upgraded rubber feet. Both types of rubber feet were problematic in my motor setup with lateral movement, which was transmitted to the turntable.

I said I'd report back what effect my changing from black belts to the (new) rust-coloured ones had.

It almost entirely eliminated the Squeak ! It's not achingly quiet but is a very significant improvement. If it had been like this from new, instead of audible from up to eight feet away, I may not have noticed anything amiss.

This result invites speculation. Here's mine.

VPI have always produced a certain look of kit. Many people like it (I do) and many don't. The new rust coloured belts are strangely at odds with their usual brushed steel and black theme. Could it be that black compounds couldn't be made squeak-free for all installations ? This would also explain why VPI made me think the squeak was mine alone and therefore of my doing - because they didn't then have a solution available. When one was developed they couldn't let me know of it without the glaring contradiction...

Only a theory, of course. Allowing it may be true - what do YOU think YOU would have done as VPI when faced with apparently random squeaky installations and suspecting the rim-platter interface was the problem ??

...just remembered....I DID have a squeek when I first got my Superscout. I was told by Harry to lube the motor shafts which I did and never had any squeeks thereafter. I used the VPI lube that looked like oil that was sent to me.
