Vibratory Tumbler

Well, I tried another batch. Pulled the last few screws and clips off my car from under the hood. Before and after pics. The mix I used this time was green pyramids, 2 cups sand chunks of ceramic plate and a cup of denatured alcohol.

Ran it for 48 hours. You can see some stuff came out nearly spotless. Others a little of the undercoat and seam sealer outside or inside couple clips did not come off. The metal bracket still had some rust. Also the stupid green pyramids blocked some cleaning action as they stuffed theirselves inside the clips. I pulled the worst parts aside for another experiment and blackened the rest.
