VPI Rim Drive vibrations

Yes I know about that. Dan and I went round and round until I figured out my issue. What I did was raise the motor assembly with four Cardas wooden blocks still with the soft sponge rubber feet on the unit, which placed the rim drive in exactly the right place on the edge of the platter. With the newly designed Bearpaw, you don't need those 4 wooden Cardas blocks. Regarding vibs from the floor....I would make sure that my supporting table is solid, and would still get those Bearpaws...especially now that it is a custom fit. I know that it will prevent the arm from rocking. I think that's the best you can do. My floor is very solid French travertine tile...one reason I bought this house

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.
