Get a bag of the white granite stone from Lowes and throw some of that in there for a real nice deburr job

Use some glas botle or nut shel for polish

If you coat the outside with spray on bed liner or anything rubberized it will make it much quieter. Also try pea gravel as a media or river stone that may work too. Great Idea! If it could be slowed down that would help too.

What a great idea! I might try this with some corncob bits and some "brass tubes".

the carbon on those brass tubes doesn't come off super reliably with corncob bits, I like a vibratory tumber and steel pins, gets the boom button hole cleaned well
