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?

@nandric , I had to look it up to type it so I can assume that anyone that has a computer could do the same.
@toddbrom, it’s amazing where you can hear the benefits of the product dynamat, I keep a roll around and love it
Herbie’s grungebuster dots work well between my rack and the maple block that is the platform for my turntable.
