Brass shiner. Wanted to try different shining methods so I put them all in one. I have corn cob, walnut, and not stainless steel media but copper wire for media. The copper wire work well. I have other tumbling barrels I will try walnut and bb's. Here is a video of it. Might end up putting some sort of fan for drying the wet media stuff. Any comments and suggestions welcomed. Thanks for look'in.
