try squash balls cut in half. These are hollow rubber balls.
Also, you could cut two matching sheets of board and in between them glue a bicycle inner tube. You can then inflate this to whatever psi is necessary.
Good luck

Hi,
Another variation on the squash balls in to use them complete.
In this case you fit retaining rings to the plinth, a simple tube.
Then choose your speed of squash ball, I think yellow spot.

experience with squash balls and tubes
I have used squash balls for over 2 years. I did not monitor regulary, but noticed just a month ago that my table (sandfilled) was tilting.
The squash balls (yellow dot) detoriate unevenly. They are still laying on my workbench, first the dimension was eliptical ball Dmax😀min=3:2, after the last weeks the relaxed to 4:3 average.
Now I am using a tube, not glued, fixed between to rims.
By the way I only use this construction because of WAF. I have to keep my deck in a kind of cupboard, when not in operation out of sight. When WAF is not a problem I would first experiment with rigid construction and different top platters, wood, MDF, reinforced glass, marble etc. and some spike type of things.
It is my feeling/experience that it is more important to get the "energy" out of the turntable/deck then the otherway around.
In my case the cupboard construction urged me to do it also the otherway around.
For what it is worth

Thanks guys! I have started using a bike innertube and all traces of sound and vibration are gone, not only in playback, but when I put my ear on the plinth and bang on the table that the turntable is sitting on! Man the bike innertube idea is fantastic. I am drawing up plans to build a platform that will hold the innertube and allow the valve to come out the side with teh tube in an evenly distributed labyrinth like shape. I will post plans sometime in the future.
Have been using bike inner tubes for some time now to support my modified Thorens TD 125 and they certainly work.
The only thing I have found with them is that tend to go flat over time and need reinflaiting - this even happens with the thick 'thorn proof' ones that are used by mountain bikers. I suspect that the valves could be the cause?? I intend to seal mine when I get round to spring clean my system.

Here is a variation on the inner tube design:

Also has the valves accessible from the exterior of the box as Harderror suggests.

Look for comercially available Isonodes, nice dampening spheres to glue under cabinets.
I made some myself, from 2 component silicone which hardens till a soft rubber is left. I molded them in contact lens disposable packages, they had a half sphere cup. The rubber is used to make a mould of an ear Concha for hearing aids! (am now educated for hearing specialist)
The rubber works fine but is a little slippery, the speaker which i provided the stands can be shifted easily from its place. Maybe the rubber has to be grinded a little with sandpaper.
