Nice job man. Unakites are some of my favorite tumbled stones.

I really want to figure out what I am doing right/wrong with the rotary. I know it CAN be done, and I believe that if I can acquire the knowledge to rotary well, that if/when I get a vibe, I'll just be that much better. Plus, I figure if I'm making bush-league mistakes with a rotary, they may just be magnified with a vibe. Sure. I'm no expert, but for me, getting a good shine using a rotary meant sticking to fundamentals and understanding tumbling physics: - Ensuring hardness of tumbling material is relatively uniform. - Adequate space-filling, cushioning material; Minimize impact, maximize friction. - Lots of patience. Stage 4 can take longer than 7 days. Most folks stress the importance of eliminating contamination (coarser grit leftover from previous stages), which is a good rule of thumb. But I don't meticulously scrub to remove every particle of grit, and my batches turn out just fine.

Hey Eric - I was experimenting with leather and wood as alternatives to plastic pellets, which I find annoying. I know that there are some very knowledgeable folks here who consistently achieve that 'wet' shine using rotary machines, but i agree with orrum. For someone impatient like me, getting a lot-o was the difference. Hit me up if you want to check out my setup (and trade some material).

I've used stuff like pieces of leather and chopped up wooden dowels for cushioning in my barrels.

The color looks right for amazonite, but the surface looks different from the specimens and other feldspars I have.

I've never used a grinder on my tumbles, but it's certainly a faster way to get to the shape you want or grind out imperfections. No harm is giving it a go and seeing if you like the results. Stage one can be maddeningly slow.

I wouldn't worry about making mistakes or strict adherence to protocols. Mistakes will be made and you'll learn from them. Even the most experienced tumblers get cracked and undercut material. Those are the ones that go back into the Stage 1 pile.

Picked up some obsidian and would like to learn knapping. Probably going to continue watching Youtube videos and dive right in.
I see that flint knappers use copper tipped tools. Are these necessary? Are there other household items I can use as a pressure flaker? I'm a cheapskate and would like to avoid buying tools if possible.

Open to whatever folks are willing to sell. I already have an abundance of mollusks, corals and sponges, so those are lower priority but still something I'd consider buying.

Thanks all. Sounds like it's less valuable material because it's heterogeneous.

Hello. I acquired a slab of something labeled as "disseminated turquoise" from Zaire, Africa. Anyone know what that means?

Awww. Thanks man. Frank Psycho is a trustworthy, stand-up dude. And Michael Fossilman is also a great trader with really nice material. Awesome community.
