For sand to work here in friction does it not have to be load bearing itself: i.e. inside a steel cage that propagates the vibration through the walls there will not be much friction, no? What you want is a sandcastle.....


Vibrating steel walls set the sand grains in motion. They dissipate the energy rubbing one against the other, down to some frequency when the sand
sarts to behave like a solid. Ever run on a beach?

I start to get Paul's idea I think. I could couple the rack to the wall through some kind of elastomer/oil dampers, used e.g. in motor bikes...interesting!

I'd like to end theoretizing at this point, change the oil in my TT, sit down and listen. Will report how the rack works in practice in few days.
