Cool beans. Hope you update with pics on each clean out. Petosky stones can be tricky to get a polish on. You may want to check out post by Jugglerguy. He’s had some amazing result with them and has posted a lot of info on how to do so as well.

Nicely shaped by Mother Nature rockstock. Rounded by nature makes fast tumbles. Fortunate situation.

He’s had some amazing result with them and has posted a lot of info on how to do so as well. Those aren't Petoskey stones, they're puddingstones. I find and tumble both. Petoskeys are soft and tricky to tumble. Puddingstones are hard and easier to tumble in some ways, but difficult in other ways. The quartzite matrix always ends up with little pits in it, which frustrates me. They guy who has the most experience tumbling puddingstones is Drummond Island Rocks. rockstock, are you from Michigan? I'm in Alpena.

Nice looking puddings in the mix. It has been awhile since I have rotary tumbled so I cant give advise on that. In the vibe tumbler more time is not better. The problem with the matrix undercutting just gets amplified the longer they run in each stage. Pudding stones were the first stones I started with 8 years ago and after tumbling hundreds of pounds of them I still get frustrated by the undercutting. They are hit or miss though. Some have a tighter matrix that comes out pretty good and some are just problematic. Good luck. Looking forward to polished pictures. This picture shows the undercutting. The damage comes after the 120/220 stage. When the 120/220 stage is complete they feel completely smooth and look great. After 500 they still look pretty good but 1000 and polish is where the problem happens. Some still come out good though. Chuck

Unfortunately I won't be able to vib these, they are all fist size and larger. Some to mess around with and see what kind of polish I can get. Can always cut them up if it doesn't go well. Waiting on larger saw to cut some up. Not sure if I'll get to the point of breaking some up, but may be my only option to have smaller ones to tumble. I had a few large quartz rock this size that seemed to smooth out pretty well after a week or so, little different with the multiple hardness parts but willing to find out

I did a fist sized one in a three pound barrel recently. It hurned out as good as the one in the Lot-O do. I did one big rock with the rest of the load ceramics. After rough tumbling, I went for one week in 220, ten days in 500, and two weeks in polish.

Two rotary with LSAs and one big one with Puddings, vibes are empty at the moment. Just getting post-winter started up little by little

Those are coming along nicely. It'a always hard to know when to stop tumbling puddingstones. They never look perfect, but how do you know when it's as good as it's going to get? I usually just make sure all the big holes are gone.

Left these tumbling for awhile since it's not a quick clean out. Yes... I am tumbling that many large rocks at the same time in the same tumbler. Experiment and impatient of not wanting to do just one or two lol. Rounded off pretty nicely from the rough shape they were originally. At the very least I'm liking the rough rounding and cleaning up that's done.

Nice pudding stones! What's the green/blue/gray one at the end?

Thank you! It's a jasper I assume. Similar to the below photo, has some rough parts and a very smooth part. After tumbling a lot more of the smooth part was exposed with just a small darker banded spot left on the top.
