of course you could build a box of wood with carpet on the inside
that you tumbler goes in and it would cut down the rest of the noise
too. Aaron, kinda new here, but I read all the postings
Hello all noisy tumbler operators. I have an idea that those in the
shop driving you crazy were being run on a hard surface, so putting a
box over it isn’t the answer. Nor is a sound-proof room practical
for most. Try buying a thick as possible carpet remnant for the
floor, covered with a heavy as possible rubber mat of the
non-flexible variety. Then your tumbler will purrrrrr.
Comparatively, that is. Works for me.
