Tom,
Glad to read in your Faq that you also like sandboxes. I improved my sandbox by cutting up the wood plinth that rests on the sand to isolate suspension towers, motor, and flywheel from each other and prevent vibration from being conducted across the plinth. Then I converted my TT from sprung to hard suspension to improve coupling to the sand. The set-up was then significantly improved by adding springs to float the 300 lb. TT/sandbox combo. It's likely that any thick maple platform would similarly benefit from springs. The sandbox or thick maple acts as a dump for TT vibration, and the springs decouple the entire assembly from earth.
