How to make DIY Sandbox isolation table

This was my first attempt at building an isolation platform – sandbox.

Design layed out before stepping into the garage to start.

Painted with Krylon Semi-Flat black and then weathered stone finish. Topped off with six coats of semi-gloss Deft.

Here is the pebble finish. The color was black sand. Then the final coats with Deft. The glass beads are size number 10 and came in a 50 pound bag. I used about half the bag.

Here is the finished platform filled with glass bead media used in bead blasting. Finer than sand, white and covered with a piece of 1/2 inch glass.
The hardest part was getting the “sand” absolutely level. Instant difference in the sound quality from the Rega. The rumble that I had been experiencing since installation of the high output Audio Note cart is gone.
