Racquetball isolation platform perfection

Racquetball isolation platform perfection ... and DIY style to boot ! Thought I'd share with you my experiment that turned out working perfectly in my system.
Basically I copied a Ginko Cloud platform using $5 worth of racquetballs from Wal Mart and some 1/2" Birch plywood. I used a specialty grinding stone from a local tool store that makes a perfect 1.5" concave in the wood. Cinched it up in my drill press and drilled it down about 1.5" in from every corner, and went down about 3/8" deep. It's allows the balls to move back and forth by about a half inch, and when the top platform is added the CD player simply " floats " on top. just like an original Ginko. This EASILY bested several different cones I have in my collection, a set of Isonodes, a set of Symposium Rollerblocks, and a innertube isolation platform.

Total cost ? $15.

The bass is the tightest and most defined I have ever had in my current system. It made amazing amounts of good things happen under my Lexicon RT-20.

Try it for yourself, it was a winner in my system.

I made something similar under my turntable. Basically my TT sits on a butcher block, then I put 9 squash balls under that, then there's another butcher block floating in a sand box. I didn't route out any cups for them though.

Try the squash balls instead of racquetballs. They flatten down quite a bit more and do not bounce (squash balls are essentially dead). Here's a picture where you can sort of make them out:

Here's a link to the balls I used:
