look into laboratory equipment, i bought one from a lab and was from the 50s..still works like new..its a vibratory cleaner and was used to clean circuit boards, i made a container to bolt onto it and its a vat...i can get pullies in it..and it takes 2 people to move it..there 1 1/2 inch block of steel bolted to the bottom and that gets bolted to the floor..

ive never blasted or prepared anything..once you use an abrasive it changes the surface.,,if youre gonna blast it,,why even tumble it..

the media and the type of liquid will determine how it comes out..i use green pyramids and just plain old vinegar does wonders..put a little dawn in it and its cleans everything..some CLR and it de-rusts..and simple green is amazing too..ive been tumbling for 15 years,,,i would never sell my tumbler
