Sandbox Design Advice


I understand the recommended design is to build an open wooden box plus a loose lid (possibly granite) which is slightly smaller than the internal perimeter.

Fill the box with kiln dried sand, float the lid on top of the sand and then component on top.

Heavy duty sorbothane feet for the box.

There were a few design details i couldn’t find on the forum and so pl can anyone advise on:

  1. what size should the gap be between the lid and the perimeter?
  2. how deep the sand should be for a 52 kg power amp (114lbs in old money 😀)?
  3. i am going to use a carpenter to make it for me (pine?) and would like a professional finish in black - any suggestions? 

thanks very much - advice is much appreciated.

With regard to the filling, my understanding was that vibrations passing through the filler would cause the particles to rub together and the kinetic energy would be reduced through friction turning it into heat.

If this is correct then the best filler would be the one with the smallest particles and highest surface area.

I have no formal scientific education and the above is just me regurgitating stuff i have read elsewhere so happy to be corrected if it’s wrong?
