What however is very practicable is some kind of sealed TT mat of 2-3 cm tall, fully filed with mercury. It would be 10kG of inertial mass – it might work… The question is how?
Ah, this is a GOOD idea! Wood would be the easiest material with which to make a prototype, and it can be readily turned on the lathe that is used to make horn loudspeakers. I bet the same craftsmen can do it for you. The inner chamber can be sealed and filled with mercury from amalgam. Or perhaps a plaster model can be made? I am sure this is how Jessie would do it.

I still think that a record clamp idea is the easiest way to start to experiment to see the sound. My concern is that the mercury may cause some ringing in the platter.
