I'm in the process of chopping a nice little DD deck:

Which is already much better since I removed the dodgy 'suspension' and
clamped it directly to a piece of, er, kitchen worktop - which has produced
a much richer and 'fatter' sound already, but I need some feet which will
work at least as well as (and look better than) two bath sponges and a
packet of Fusilli...??

Nick G has mentioned squash balls which, sitting in little wooden rings,
would work but I'm curious about wooden cones, which I can buy for a coupla
hundred quid or make for about 50p (still not decided...) - what I want to
know is which way up for best 'isolation' (energy dissipation) - points up
(from a concrete paving slab) or points down...??

Any Stress Engineers here? (Or I'll take the opinion of an ordinary engineer
who is at least a little bit wound up.... !! ;-)


Totally unstressed today - but here we go anyway.

Wooden cones wont dissipate any energy to speak of, whichever way up
you put them. They'll transmit every footstep and passing lorry. The
squash balls are a great idea though. A better idea than wooden rings
might be a pretty sheet of wood with holes drilled in appropriate
places, about half the size of the squash balls. Is that grey plinth
thing heavy? If it is then try to keep that above the squash balls -
sprung mass is what it is all about.
