I picked one of the Chicago-Electric 2 canister 2x's 3lb polisher/tumblers.$43 and.some change. Sure makes for some shiny brass. Had 5lbs of pins on hand, couple drops of dish soap 1/2 tsp lemi shine spin em an hour presto. Cleanest brass I've ever cleaned. Plan to build a little bigger one but this cheapo tumbler proved to me just how well this method works. Ran 3 loads today of 223 cases I've been ignoring for a while because there were approximately 300 to clean and process. This was just the boost I needed to get it started.

Worked well on larger (7rm) cases too. Don't expect it to last very long (already had a screw fall out) but like I said it was an easy way to get started without much time or money invested.
