I'm trying to match feet underneath Krell FPB. I want it to be isolated as well as possible. The platform and Krell weights 75kg. Often the feats are "one size fits all" and often they are expensive.
Therefore I want tailor made feet. Calculation suggest Sylomer SR 42, 25mm x 55mm x 100mm. That gives an optimal reduction of vibrations for a fraction of the cost.
I also have to make a metal plate on top and bottom of the Sylomer, like a hamburger, to stabilize it.
To cut out the right proportion Sylomer is the first step.
