Someone made a post earlier about tumbling being rocket science. And you all know me, I have to open my big mouth and speak as if I know what I am talking about. So ... I have decided to do exactly what I said to do in that post. After I get done with Obsidian batch, I am going to do this batch. I am going to load the barrel, load the grit, and add pellets and water and then let er rip for a bit. I will not handle this batch methodically (I rarely do anymore). I will let it go for say 2 weeks and not check it at all for that time period. Here are the pictures of the rough (mostly rough scrap from other pieces). This rough is similar in MOHS and I will start it only with 2 tbls of 60/90. I will add the plastic like I always do (I like plastic pellets and most people do not) and then fill with water almost to the top like I always have. I do know that there are some of these pieces will not survive (as they are too soft) and this is okay, however, I do this on purpose as I always try to add some scrap to all my loads as additional and different cushioning. I predict that there will be some pieces that are spectacular and some maybe not so much. You guys be the judge. Let's see what happens ...

I know you have your own method and you are on a mission, but if you find that the edges are not rounding quickly enough, consider this ...
Maximize the grinding action in Stage 1. Do this by eliminating the pellets and not over-filling the barrel. I fill to 2/3 full with rock, and 1/2 full with water. This gives the rock plenty of space to tumble and maximizes the grinding action. When you reduce the space, you reduce the grinding action and increase the time necessary.
I have even tried 46/70 grit in Stage 1 for some extra grinding action. This doesn`t appear to make a significant difference because the SC grit breaks down as soon as the tumble gets going. Chances are, the 46/70 has been reduced to 60/90 within the first few hours of tumbling.
Nice pet wood and good luck.
Darryl.

Hey All!!
Depending on how the river rock batch is doing will determine if I start this batch this weekend.
I need to check the obsidian batch that has been in pre polish since January 19th.
I cannot wait to get this batch started with my own brand of tumbling and see if I am gonna shoot myself in the foot or not. ;D
