I found out extremely fast that the plastics are nothing more than a pain in the ass, I use 4 sizes of ceramics in my obsidian both in the rotary and in the lot-o to finish polish them. Looks like you have a great batch coming!!!!

nice result. just one word of advice. Reverse the order of the storage of your grits and polish. The logic is heavy things at the bottom and lightest at the top. Heavy grit will always contaminate downwards rather than upwards.
Cheers Scott

I actually read that in another thread and when I setup my new shelving, everything is now the opposite of what was shown here. But this is good advice!

Well, this batch has finally finished. This material is impossible to photograph with my crappy homemade setup. And my lint-free cloth must need to be replaced. 46/70 SiC in the QT66 until ready 48 hours in each - 120/220 SiC, 500 AO, 1000 AO and polish. Here are the results:

Perfect! Now that's a good looking batch. I'm excited to do an obsidian batch soon.

Those look really great. Nice work on the tumble and really nice material Tommy provided.

Why did you keep them in a jar of water while they waited for their teammates to be ready?
Simple curiosity.
Nice result!

Everything was nice and smooth when they went in. And I bet there was maybe 25-30% large and small ceramics added. I guess it's the nature of the material. I'll do a little grinding on the new flat lap and throw them in the next batch.

Awesome batch!
What polish did you use? I finished a batch of obsidian this summer but ended up with a matte shine using TiO2.

Guess I'll have to try that when I start the tumblers up in the Spring. Thanks.
