A sand box? Literally? Some bags filled with sand really helped
with my turntable. Make sure that it stays in the bags.

There was a turntable stand with the creative
name "lead balloon" that worked like your sand
box (I actually don't know what substance the
"lead" balloon used for ballast).
You might also consider locating the oscillator
in your garage/basement on the concrete. The
ideal setup is to pour concrete for a "floor
safe" sort of container and then mount the
oscillator inside the container below ground
level. For the advanced user, dig a 5 foot
deep hole with a post hole digger than put
in a pipe with the oscillator at the bottom.
As a free bonus, you will get temperature
stabilization.
