VPI Rim Drive vibrations

Well, dear Stingreen...when I've bought my house I didn't have analog setup yet :-) After talking to Dan from edenSound, I'm going to get his new gizmo - polymer/brass TerraCone:

"Yet for the ultimate in single-direction energy transfer and simultaneous isolation, you might want to step up to our hybrid polymer/brass TerraCone .
With a model sized specifically for the VPI tables w/ outboard motors, the TerraCone is our best and most sophisticated vibration-control foot for replacement of the stock VPI feet. It has a dual-material construction: solid high-quality brass for one-way egress of energy, and our proprietary TerraStone high-density acoustical polymer for isolation of the table from structure-borne and room-borne vibes. The TerraStone polymer is the most inert, neutral vibration-absorption matrix I have tested in more than twenty years of listening."

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.
