  Hi all,

  The below URL is of a simple table top test vertical setup I tried =

  hinge/pivot, main spring/s and seems to allow some limited mass weight =

period ran from 1 to almost 2 seconds...probably
  typical for such.  This is ONLY a test vertical mainly looking at the =
pivot and flat springs used; I don't really know
  if its really worth pursuing.  Their is 3 "varieties" on the page; =
with the last one looking much more potentially useful. =20
