Any Way To Damp Ringing Stands Without Adding Weight???

I had to dampen my thin and ringing old Lovan Classic stand (which was to hold up a big new turntable).

I didn't care to pour crap of any sort into the poles.  So  I lined both the insides of the metal shelf bracing, and the vertical poles, with this sticky sided sound damping material:

Whatever I lined with that stuff really stopped ringing.

I also had a bunch of this stuff left over from my trials in sound isolation for my turntable stand:

So I cut up chunks and stuffed it into the hollow poles of my stand.  (A lot less messy than pouring any fine grained particles).  The result is a very dead sound when rapping anywhere on the treated stand.

When I put my Solid Steel stand together, I noticed there was acoustical foam inside each tubed pillar.  It is dead quiet.

Do not use kitty litter ever. Construction foam is a good idea or bean bag chair filling, small round Styrofoam marbles.
