The slant tumbler has a cap that allows gases to escape. Tumbling metal generates lots of gas. aluminum grip fittings and brass wire hooks Run 12 hours with water and AO 220 broken grinding wheel media large enough to not get jammed in holes. Semi dry: This mystery machine. Barrel design may be a real speedy way to do step 1. It was engineered by some heavy hitters decades ago.

Dry tumbling metal probably won't. The cap can be removed and the action watched while tumbling with this machine. The action of the tumbles is very different from a round barrel. The tumbles travel from left to right instead of falling down a hill. The upper action zone where there appears to be the most rubbing action is the full width of the barrel and is as mentioned almost horizontal. I would like to have a larger say 15 pound version of this shape barrel to see what the step 1 grinding rate would be.
