Using Maple Butcher Block Under a Turntable


When using a maple butcher block under a turntable, what is below the butcher block?  Cone?  Soborthane pucks?  Does it just lay on the shelf?  What are people using and how of they mounting the block?  How are they mounting the table on the butcher block?

Special mix concrete isolation platform. More dense than normal concrete but a third of the weight. Works fantastic under everything. Can get them specially designed in any shape thickness or color.

One of the best characteristics of Spam is that it has no expiration date. It's good forever even if it's left out in the open at room temperature.

Sauerkratut cans work just fine under tables manufactured by the Swiss and Germans.
