What is under your TT, cheap islolation?


I am looking for a way to isolate my turntable without using a shelf bolted to the wall. I am trying to save money while I re-configure the room. For now my turntable is on top of my stand but you have to tip toe around the room. I am wondering if a big rock iso platform (or DYI version) or some iso nodes under a butcher block would help with the bouncing turntable? I have two tables I am testing at the moment, one is a Thorens TD-160 & the other is a VPI HW19 MKII, both of them suspended. The floors are pretty sturdy, it is a dedicated room over my garage with serious supports built in to the floor.

Perhaps rather than hanging a shelf on the wall you could just attach the existing rack to the wall so that it cannot rock when the floor flexes. In my case, the motion that caused the problem seemed to be horizontal, not vertical.
As an update, I cut some raquet balls in half & installed them under the isolation platform. It certainly helped with the footfall issues but if the TT does get moving the balls keep it moving, the needle bounced almost half way across the record until it stopped. Under normal conditions of moving around in the room the raquet balls are a definite step in the right direction.
Build your own. I have an old AV clamp rack where inbetween I clamped two cinderblocks & some cut 2 X 4's to raise platform. Using spikes & cones, a level you can construct a wonderful turntable stand. I can actually jump up & down right next to my table while playing and does no skipping whatsoever. The clamp rack was by I believe Michael Green......Enjoy.
