This thread has been a great help to me as I'm a sonic virgin stumbling along a rocky trail. Now that I have the manual, I have a valid starting point. I had only been using 1/2 the recommended grit amounts- now I can get my rock on.

Yep, it's a bit old, but beautiful work nonetheless. The shine on the "rotary only" gives me hope (and something to aspire to). Drummond Island Rocks , do you recall how long you left your rocks in the different stages following your coarse grind? If you already mentioned it, I missed it. Thanks and regards. Dave 46/70 SC as long as needed 120/220 SC 7 days 500 A/O 7 days 1000 A/O 7 days 14,000 A/O polish 14 days That is a whopping 5 weeks after stage one. Chuck Hmmm. I went from 500 to 1 micron polish, which based upon my research is 14,000. And, in that case, I only ran it one week just to get a baseline. On my next batch, I was going to try 14,000 for two weeks to see what happens. Seeing your results makes me wonder if I should insert 1000 AO. Then again, I'm wondering if I should increase my 500 AO from 7 to 14 days to break it down even further. Or, is there is distinct advantage of dumping the 500 AO after one week and going to 1000 AO? It obviously works for you. Very impressive. Regards. Dave

This is what the Vibra-Dry polish looks like. This is 15,000, but all of the polishes look identical in regards to the size of the media carrying the polish. Thanks for the info. I looke up Vibra-dry and its now called Vibra-dry plus. It contains rice and stainless steel shot in addition to the walnut shells. I'd love to try it, but it's really expensive. I guess if you can reuse it, that would bring the cost down. It's very intriguing. Omg'sh THANK YOU for posting this picture!! I bought a used machine a while back and with it came a container of these weird pellet thingys that the label had worn off. I have this stuff!! Not much but enough to try without having to purchase first.

That is Walnut Shell Media. A search revealed that you can make your own polish and tumble dry. Here is a general description . . .
--------------------------- Walnut shells are used in many polishing and/or deburring applications. Walnut shell media is used for polishing or cleaning fine metals, alloys, mechanical parts, shell cartridges, eye glass lens, rocks, stones, coral, ivory, beans, and seeds.
Jewelers use walnut shell media treated with rouge in both tumbling and vibratory applications for polishing gems and fine jewelry.
When polishing the media size should be small enough to freely pass through openings or large enough to avoid lodging in openings or crevices. ---------------------------
