That's something to consider if I go back to the dry tumbling smaller volumes of brass, thanks!
Sorry for the hijack. Back to the mixer. Jerry Miculek said in his vid that he'd do a five gallon bucket of brass along with the same amount of water in what looks like the full sized mixer. I assume proportionally less for the smaller.
The work area at my club for the brass cleaning (also for cleaning up and ingotting scrap lead and for other casting) is just about done - pavers over gravel for drainage. Turned out nice. Maybe too nice - the club chairman thinks it would make a great place for a couple picnic tables and a grill. Sacrilege! Almost as bad as turning open land into a golf course instead of a rifle range.
