This is my second attempt at using my UV-10. These are mostly slabs I cut with my workforce tile saw. They have a really good glassy shine but it does not really show in the pics. I cut them as slabs as I hope to have a cab machine by Christmas. I've noticed you really have to pack the vib to the top to get the best results, especially with the polish. I've been using my 2000 psi power washer after each stage to clean the rocks and the bowl. It does a great job of cleaning between stages. I used 220 grit for 4 days (recharging a little daily), 600 for two days, 1000 for two days, tin oxide polish for 6 days and Borax for 3 hours. Pet. wood from the Yellowstone river and a uncut agate  Quartz from the Columbia River  ?? stones from the Yellowstone River  Quartz/agate stuff  Palm wood? Got a big hunk of it waiting for proper cutting  Thanks for looking and appreciate any suggestions on what some of this stuff is! |

You might get better results by doing longer stages. And not sure what you mean by re-charging a little bit each day. Do you mean just adding more grit without cleaning? If so, I think you might be defeating the purpose. Part of the grinding process involves the breaking down of the grit in each stage. If you're constantly adding fresh 220 grit, I don't think you can achieve that.

Thanks for the suggestion! I put in 4 tablespoons of 120-220 at the start and then added a tablespoon full each day. I guess I was thinking that the vibe breaks down the grit much faster than the rotary and adding grit would keep the old grit braking down and add some new to keep it going. I'll try washing it out at day two like Randy's vibe directions say next time. I only went four days as I was just trying to grind off the saw marks, and I'm too impatient. Waiting the 6 days for the polish just about made my wife crazy as I had to check the progress probably 4 times a day. A couple of the wood pieces I didn't cut and it shows. My brother wants them and he really liked the outside wood patterns. He just wanted them shined up a bit.

Nice batch,you have some nice material.I do a lot of slabs in my vibes and I get the best results when I add a good amount of round stones from previous batches.

I'd like to see an id of the last photo. In the top photo where its positioned are the three smaller pieces the same material cut at a different angle?

I'd like to know the ID of that last photo too! The little pieces next to the big slab are the same material but from a different small stone that I hacked into pieces. I rock the big slab weights probably 4 lb's. It's tubs are filled with quartz. The outside looks like concrete but polishes very well. Looking at pictures on the internet it could be pet palm or some sort of fossilized coral. It's from the Yellowstone river gravel beds by Miles City. 50 million years ago there was a inland sea there along with palms and redwoods. Lots of interesting stuff in that river due to the Yellowstone eruptions.
