VPI Rim Drive vibrations

Thanks for the information about the tera stone. Let me know how it works out

Krell303,

If you need to isolate your TT from the floor yet also need it holding rock steady vis-a-vis the motor, the obvious solution is to place both TT and motor on a single platform, then isolate that from the floor. Vibraplane, Symposium shelf, Minus-K, a DIY or whatever.

Two engineering requirements, two solutions.

Some Canadian garage business tried the rim drive approach and it failed miserably.

There were numerous revision/upgrades in the first year all of which resulted in excessive motor noise, erratic speed, and overall poor performance.

I had updated my plinth feet to TT Weights brass Soundpoints before adding a single motor rim drive flywheel so never heard of this issue before.

In order to help seat your belt in the flywheel track, place a round toothpick or other small diameter object (small drinking straw etc.) between the flywheel grove and belt. Run this around the flywheel circumference a few times. Make sure you keep the belt even to the grove as you navigate around the circumference. You should be able to seat the belt evenly in the grove. I use a small diameter wooden cylinder I borrowed from the kids.

I also see you have the brownish rim belt for the flywheel. Does your flywheel make any noise when it touches the platter? Regardless of the contact pressure, my flywheel makes a high pitched noise. I have tried a few things to reduce/remove the noise but cannot eliminate it.

Maczurak, I did try to seat the belt with a round polished pin - it made the wobble less visible but still...No, there is no noise at all.

I hope to receive 4 TerraCone for VPI SSM Height-adjustment hardware Point-receivers from Eden Sound in the next few days and will post an update.
