Any thoughts on a solid hickory platform under my tt

"But i am searching out granite, corian or wood options(honestly i would perfer it to be black so i may stain or paint it ).I have 6"thick walls and a steel wallmount stand with massive isolation..my floors are rock solid i can have my table on top of my stand shelf mdf (spiked and filled with sand) and jump on my floor and nothing comes through my table.with it on the wall i could sit on the shelf."

As fate would have it the Earth's crust motion forces the entire building to shake and vibrate like a rug being shaken out, such that even heroic attempts to stabilize and keep everything "rock solid" actually exacerbate the situation. Since isolation can be defined by the "ease of motion" in the direction of the external force, say the vertical and the horizontal directions, for example. This ease of motion concept is actually the opposite approach from the "rock solid" approach. The most common ease of motion approach for component isolation is mass on spring. I have used laboratory black granite mounted on stiff springs though you might have to look high and low for a large laboratory granite slab. Bluestone is much easier to find in say 3" thickness and works well with or without springs.
