Are you having trouble with your rock tumbler? Trying to figure out why your rocks aren't getting shiny? I have about a dozen years of experience helping people learn to tumble rocks and troubleshooting their problems. Let me help you figure out what you might be doing wrong. There might even be a tip or two in this list for more experienced tumblers.

Kingsley North is a lapidary store in Michigan's U.P. They make a great cab machine and sell many other brands too. They have a huge selection rough rock, tumblers, grit, jewelry supplies etc. at good prices. I buy most of my coarse grit from here in 45 lb. bags. It's the best price I have found. If you buy using the following link, I make a small commission.

This was a good over all review I'll share it with the Rock Club members who are new and trying to choose where to begin. We're pretty much on the same page with just those couple difference in how I load and the amt. of grit. And nice this is all about using the Rotary tumbler all the way. The only thing I can add for anyone else reading is; IF you do have a failure and it happens; you can start over and while your rock will be smaller you can achieve a good result in the end. Thanks again. A great resource.

[@MichiganRocks]

That's a good tip, Margie. I wish I would have remembered to include that because it's a question I get from time to time. People seem to think that they can mess up their rocks beyond repair, but that would be extremely difficult to do.

[@user-dx6in7lu4q]

I hope to have some pix to share to prove that coming up.

[@OntarioRob]

You were kind enough to give me a lengthy & very detailed plan to follow for the entire process. I do everything you've just talked about in this video, so I know I'm doing it right. I did, however, start my 1st stage with 46/70 grit & made my 2nd stage 60/90 grit. It's an extra step, but I'm really pleased with the results. This is definitely not the hobby for someone who's impatient. Another thing I try to do is keep all the rocks in the barrel the same hardness or at least close to it. The best thing I've done is ignore the tumbling instructions & asked you for the advice I needed to start my hobby. Thanks again, Rob. You've made tumbling very enjoyable for me

[@MichiganRocks]

I finish most of my batches with a vibratory tumbler and I don't find that it's all that important to tumble rocks of the same hardness. I have a feeling that it's more important with rotary tumblers. What advantage do you see by adding a 60/90 step after 46/70? I've never heard on anyone doing that.

[@mitchellmajor8984]

I need help in tumble polishing BLACK CORAL from Maui. Have a Hawaii State license to harvest the coral. I need direction. Thank you Mitchell Major

[@OntarioRob]

@Michigan Rocks I used to polish metal bumpers for a living & once in a while I'd come across a bumper that needs a very coarse grit belt. I tried moving down to a finer grit belt & it removed all the coarse grit lines from the previous belt. Once the blemish is out, it took forever to buff the grit lines out, so it's that theory I'm using. So far, I'm getting great results. Tumbling rocks of the same hardness just makes it easier to move the majority of the batch to the next step. Keep in mind that I'm just using my common sense. If you're tumbling rocks that are a 7 on the hardness scale, they're all done around the same time. I've rarely set some aside & added rocks. My 1st step lasts a minimum of 2 week. If there's the slightest imperfection, the 2nd step of 60/90 takes care of that for me. The 60/90 step runs for about 7 days & the results are great, but I don't recommend starting out with smaller rocks or throwing in some softer rocks. The first 2 stages really grind them down to a very smooth feel. No blemishes, cracks, spawls or the like either. The first 2 steps do an incredible job

[@irishguyjg_2ndchancerecovery]

Ditto. Absolutely. Well said BFBR

[@MichiganRocks]

I haven't tumbled coral, except fossilized coral, so I can't help you out. Sorry.

Those stop-motion transitions were really clever. Great job!

[@MichiganRocks]

Thanks!

[@morganwright6388]

Along your point about choosing the right rocks to tumble, one thing I eventually learned was that regardless of the type of rock (chert, granite, quartz, etc..), the shape and characteristics of the rock matters as well. One thing I had to learn was that if a rock has a big hole or crack in it, well then that rock is going to end up being pretty small by the time I moved it to the second stage. Thanks for the great info. Your videos are where I go to if I ever run into a problem or need more information. Thanks for the help!

[@MichiganRocks]

That's very true. Depending on the crack, sometimes I'll break the rock along the crack to eliminate it.

[@morganwright6388]

@@MichiganRocks I take a lot of my rocks to the tile saw before putting them in the tumbler. It saves a lot of time on the first stage.

[@MichiganRocks]

I don't do much pre-grinding, but I will take very nice rocks to the saw or grinder after a few weeks in the tumbler if they need a little extra attention.

[@wwright8119]

You know Rob, you really put it all together well in this video. The RTH has greatly appreciated your advice over the years and your instructional document (as well as Chuck's advice) was foundational for my personal understanding of how to properly tumble rocks, saving me hundreds of hours and dollars in the process. Thank you!

[@MichiganRocks]

The more you tumble, the easier it is to be patient. If you really like those perfect rocks, patience is what it takes. But if you don't mind a few flaws, you can sure save some time.

[@soul_adventurist]

That was an excellent summary of pretty much every tumbling video you’ve made! And the editing was phenomenal ❤ I took your advice and bought the good grit. Tomorrow, I will take my first batch out of it’s 2nd week of Stage 1. I’m excited to see the results after the 1st week turned out so well. I really do appreciate the knowledge and humor you bring into your videos. Again, thank you so much for all you do for the rockhounding community ❤

[@soul_adventurist]

I forgot to add that I really like the clear end on the barrel. I imagined the turning looked that way, but the visual certainly shows the importance of spacing. Thanks!

[@irishguyjg_2ndchancerecovery]

Absolutely. I agree wholeheartedly

[@MichiganRocks]

You're welcome. Don't expect as much change in the second week. The first week knocks the sharp edges off and they show the most change. After that, it's a little more slow going.

[@soul_adventurist]

@@MichiganRocks just took them out of tumbler. The one I’m most interested in has revealed a lot more cracks. I’m considering not putting it back in. I’m afraid they will just get deeper. All the others looking good though.

I continue to be surprised at how many people are using low quality polish, or what I consider to be pre-polish. It's a shame because good polish doesn't even cost more. I'm glad you've got it figured out.

[@lorettamartinez2144]

@@MichiganRocks Well as a beginner in tumbling rocks I didn’t know much of anything. I started with what came with my tumbler. Realizing it wasn’t working I started researching KZbin tutorials. Which brought me to your videos. After researching I learned . It’s not that I wanted cheap stuff. I also didn’t research enough before I started …I don’t know about anyone else . But that is my reasoning?

Kingsley North and the Rock Shed is my answer to your grit question, but you can ask anyhow.

[@tulazaz]

Now that I’m ready to set up my new and first rock tumbler, I knew I could find the perfect how-to video by you to get me started. Thanks Rob! Some of the rocks I’m tumbling are Potomac Marble, which is what the pillars in statuary hall of the Capitol building are made of. It isn’t actually marble, but a very hard conglomerate with a grey or red substrate. The creek I find them in, behind my local grocery, also runs along an old abandoned mine of it. The cut and polished specimens I’ve seen are beautiful, but have never seen tumbled pieces. Can’t wait to see the end results! So glad I watched you first!

[@MichiganRocks]

Hopefully it tumbles well. Conglomerates are made of different minerals, so they can sometimes be tricky.

[@MichiganRocks]

That's why I made this video. I get a lot of very vague questions from beginners who just say something like, "I just took my first batch out of polish and they're not shiny. What did I do wrong?" As you know, that requires a lot of questions in return just to start making a guess. Often, I spend time asking follow up questions, and then never even get a response. From now on, I'll just point people here.

@@MichiganRocks absolutely, it's in the works. I will be proud to show you when we get it done. It'll be a few months, we got projects going in every area of our lives and we do martial arts as well, busy. I had a small haul today while out rockhounding, it was in the 20's and very windy, but I've been able to figure out a way of finding rocks in the winter, I honestly don't see anyone else oit doing what I do too much in my area, it's basically all to myself and whoever I bring out, I found alot of smalls today and a cooler full of cuttable rocks. I really need to find a scab machine, I think that's my next project maybe purchase one, but how does one buy one of those on a budget lol, used one are close to $700. If u have any ideas on that topic, a scab machine, I wouldn't necessarily need a large scale tumbler if I could polish and shape these stones with a scab... got the juices flowing now, all I can think about

[@MichiganRocks]

I don't have a great suggestion for you. They're expensive machines. You could think about getting a flat lap instead. I don't like them as much for making cabs, but if you're just polishing rocks, it would be a good alternative. It's "cab" by the way. That's short for "cabochon", one of those domed rocks used in jewelry. Do you watch Agate Dad? He's in Minnesota too. He has a flat lap and made lots of videos using it to polish Lake Superior agates before he got a cab machine. He also has a discount code for buying one.

Thank you for this. Might soon buy a tumbler and start rocking.

[@MichiganRocks]

You should! It's a fun hobby.

[@sashakys]

great advice! thank you

[@MichiganRocks]

You're welcome!

Loved this video I learned a lot

[@MichiganRocks]

Oops, I just suggested it to you in response to your question about amethyst.

[@hubrigant]

I'm actually about to start recovering from following the manufacturer's instructions. The tiny tumbler my wife gave me for Christmas came with a small bag of rocks to start with. By the time the 2nd stage was finished, about half of the original volume was gone and there was nothing in the manual about adding something for cushioning. As a result, by the time I got through the 3rd phase most of the rocks had chipped and some had broken into smaller chunks with sharp edges. The ceramic filler I bought just arrived so I'll be re-running from 2nd through the polish soon.

I bought a National Geographic tumbler just to do a video about it. I did one video where I followed the directions and had results about like what you described. Then I ran another batch doing it my way and they turned out pretty good. Your next batch should be better.

[@OntarioRob]

Can I make a recommendation ? Run your new ceramic media by itself with some 60/90 grit just to smooth out the sharper edges before you add it to your stage 2,3 or 4th stages. Makes a big difference. Good luck

[@MichiganRocks]

Good suggestion. Thanks for adding it.

I am 3 days in tumbling my very first batch and i did use ceramic media in the first stage. I like to experiment so i will see how they turn out.

[@lindah6258]

I can tell there went a lot of effort in this video, great work!

[@MichiganRocks]

Yeah, I spent a few minutes on this one, thanks for noticing.

[@virginiarocks]

Very clever and well thought out numbering ~ very cool! Excellent video and explanations. Thank you.

[@MichiganRocks]

Thanks. I spent as much time on the numbers as the rest of the video, probably more.

[@virginiarocks]

@@MichiganRocks great job. Very impressive.

[@bethrigall7160]

Thank you so much for all the information you provided. Yes, I was one of those who tried the florite. It didn't turn out so well all of it is hazy. I put it aside and will revisit tumbling it to a later date and see if I can salvage it.

[@MichiganRocks]

Fluorite is difficult. I had success, but I can't remember exactly how. I remember trying several different things until I got it figured out. I would like to make a video about tumbling it one of these days.

[@rogeliocprinci]

I just subscribed and my first tumbler with my first rocks are rolling and rolling now ...thanks 😎

[@MichiganRocks]

That's awesome, I hope they turn out great. But if they don't, you know where to come for some troubleshooting help.

[@jonathonlafave3698]

Well I'm back here lol, I love this channel and I knew right where to go. I finally have everything to tumble. I can't believe this is happening. I'm so excited. 😁 I listened to you and ordered good grit and I did not use what came with. I believe what you said. I have ceramic and I'm ready to finally learn how to do this. I have so much to work with from rock hounding. 😎

[@MichiganRocks]

It's about time! Get those rocks rollin'!

[@wyomingadventures]

Great to know about the aluminum oxide. I have it in 1000. But now I'm going to try 8,000. I did learn from you that stages take longer than the book that came with my tumbler. I do a mixture of sizes. I've only tumbled 6 to 7 hardness so far. I haven't tried Obsidian because I'm not sure about trying it yet. Thanks Rob you're videos are very helpful!

[@MichiganRocks]

Obsidian is really difficult to tumble in a rotary tumbler from what I've heard. You need to run it for really long periods of time in the final stages. I have a video on how to do it in a rotary tumbler. That's actually pretty easy.
