Nude Turntable Project

Just thought I'd mention Dupont Corian, as an excellent, easy to work, non-resonant, very dense material, that can be built up into whatever thickness desired: (http://casf.com.au/?src=globalnav) I've personally used it in a variety of resonance defeating projects, with great success. I like granite too, but Corian can be worked like wood, machined like aluminum, comes in a wide variety of colors and takes a very glossy polish.

@Mr P- There are, "metallic" Corian colors available, that(in order to be, "metallics) contain aluminum flakes. No other Corian contains aluminum(or any other metal). I've been using Corian for a couple decades and there is no resonance or ringing, at all. Regardless of how it's suspended/mounted, however one attempts to get it to ring or resonate, it will not. It's dead within the audio spectrum. If struck; One thud will be all you'll get. Free samples are readily available from distributors, that the OP can experiment with.
