Interestingly enough, I use felt in building my layout. But strips of it go between tables as a cushion / noise suppressant. This is a trick I learned from my friend Price Bradshaw (The Shadow on this forum). My tracks sit on Vinylbed (or Flexxbed as it's called now); they are very quiet.

Do you mean between the supports and the plywood top? If so do you essentially have a floating table top? How do you join adjacent sections?
