Nude Turntable Project

Fascinating. The material. To be uniform or not, that´s the question

Granite certainly has a sound to it. I hope it works for you.

Granite certainly has a sound to it.

I hope not in this situation....?
As I'm only using the granite to create a 'mass cradle' in lieu of my stainless steel cradle, I'm hoping for no contribution to the sound of the turntable itself.
After all....when I went from the 'nude' table on tiptoes to sitting in the steel cradle, there was no alteration to the tonal characteristics of the table. In other words....the steel cradle had no 'sound' to it so I'm hoping the granite table similarly has no sound to it...🙏
We'll soon know...🕟

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.

Henry, thanks for continuing to update us with your trials. Material choice can be tricky and I believe there are some misconceptions about benefits.

Years ago I read advice to try a marble cutting board for placement under a turntable. I'm not sure how marble measures up against granite but when I checked out the recommended marble I found a knuckle rap produced an audible reaction, almost a ringing.

I've read that Corian includes chips of aluminum and it too can ring, pitch being dependent on how much aluminum.

Brass of course is also utilized to produce church and tower bells so I think shape and thickness must be critical there too.

I've also read that slate, being a sedimentary material, is actually layered so good at dissipating energy, whereas stones such as granite and marble, being more solid, do not reduce energy as well but simply transfer it.

They may not be as dense but I go back to thinking of certain hardwoods which have been traditionally selected in instrument making. At least their energy transfer (vibrations) are sympathetic with musical tones.
