Vibratory Tumbler

More pictures.

Shows the results, also the rejects at the bottom of the post.

Most the black on the parts after cleaning was the original metal blackening that did not get stripped off. Nice thing is with the alcohol it is pretty much oil free when it comes out of the tumbler. Excluding the few pieces with undercoat still on them..

Shows the side profile of using this ceramic or what ever porcelain dinner plate busted up into pieces for media. The coating surface is harder than the center which results in there always being an edge on the chunk or "media" . That makes it great for tumbling as it will have an ever present edge to beat stuff up with .

Dang 1/4" pyramids round off, loose their edge, turn to worthless beads in my opinion. Then they insist on cloging into my threads. I am going to be running sand, and larger maybe 1/2" ceramic media soon so either the sand or small grit media will get inside the threads and do some action or simply stay the F out and beat up the outside of the part.
