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?

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.   
Wow. Highly entertaining. I didn’t learn anything, but I laughed my ass off. Fortunately I was sitting on a 3 inch slab of maple, so my ass vibrations were highly damped.
