I call it Roller Base Platform
They are simply two pieces of plywood about 18"w x 16"d x 3/4"h with 6 pieces of 4" x 4" x 3/4" squares. Between them, there are 6 concave door knobs atached to the shelves and with the squares having a cut-out in a circular way. The shinny things between the mirror imaged devise are ball bearings that flout over/under the knobs giving the effect of a Double Stack Symposium Roller Blocks alike.... ( as per Listener review). The other thing you see between the cones and devise top, is a whole pad of Rubber-Cork-Rubber Mat that cost around $30 at any industrial refrigeration store and that some audio dedicated stores charge $10-30 for 4 square pieces. ( the pad can give 81 of those pieces).
The TT move around if touched but never felt down. The mechanism allows for strong movement is required but keep the system in place at the center of the cones once it stop moving.
Results... under a CD player is like magic and do much of what Darumas, Symposium and other bearing systems bring. With my TT I eliminated the feedback that haunts me before and eliminate most ( if not all) the vibrations entering to my TT even with my heavy weight DIY rack ( granite, cedar wood and cedar plywood with 3/4" long screws).
