Try to keep it simlpe. I use walnut shells also. I just deprime(not size) my brass and throw it in the vibrator. I let it run til the next day then I take it out and size the brass. After I size it I throw it back in the vibrator and let it run til the next day. Then I throw it in a bucket I bought from Midway that filters out the media, you can shake the top part of the bucket, and most media will come out. Then I have a dry clean rag to pick the cases out of the bucket and take a toothpick and push out the media that is stuck in the flash hole of the brass. Then you have perfectly clean brass. Pretty simple. I also use the dryer sheets, and dust is kept to a minimum.

IMO you can not run the vibrator too long. Once I forgot it was on and it ran for three days. No big deal, just super clean brass. If your brass is stil dirty then change your media, get more course media, and let it run. I put 4 nails in my reloading bench(around the vibrator) to keep the cleaner from vibrating off the table. They will dance around on the table top if you do not do something to keep them in one place.

I have heard the new Hornady sonic cleaner is the "berries". I have been thinking about getting one and trying it. The problem is I am not in a hurry, and the one I have works perfectly. Tom.
