Polishing a Large Puddingstone

- Learn how I polish large puddingstones.
Here are the steps I took to polish this.
I started with my normal, dry angle grinder. The cup wheel is 50/60 grit, but is way more aggressive than the soft 30 grit wheel I followed it with. The angle grinder also spins much faster than the wet stone polisher. I spent 17 minutes shaping the rock and removing holes in it.
Next I moved to the wet stone polisher. This has a soft backer, so the pads can flex to the shape of the rock. The grits and times are as follows:
30 grit - 40 min.
50 grit - 11 min.
100 grit - 11 min.
200 grit - 11 min.
400 grit - 8 min.
800 grit - 11 min.
1500 grit - 10 min.
3000 grit - 8 min.
At the end, I used a cloth polishing wheel with aluminum oxide polish. I think I'll skip this step in the future. I don't think it made much, if any, difference.

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.

My husband and I are completely hooked to your channel! We just purchased some land in Fostoria, MI with a 22 acre lake on it. It used to be a gravel pit so we have found SOO many beautiful and unique stones (including Petoskey!) so we are stocking up on all the polishing gear. Thank you for being so informative and also entertaining!
That sounds like fun. I'm glad I can help out a little.
Hey neighbor I’m in North Branch. Amazing place we live
The pudding Rock is beautiful. The client that you are doing the work for. It's going to get one beautiful Rock. Thank you for sharing how you. Buff out the Rock.
As a rock Lover and a Michigander, I love and appreciate your videos!! So so much! Im learning more than I did in school for damn sure!
Juliesunshine 333 being an eight grade math teacher, I’m not sure how I feel about that. I’m glad I’m teaching you something!
Thanks for being so kind to do this step by step as you did. Very well done. What an artist (and teacher) you are. Rock polishing aside, you are quite a good instructional video maker. Bravo!
Thanks, Rick. I'm trying.
Really appreciate your breakdown of your process & showing each step, I get both new info and confirmation of my own approach. Beautiful pudding Stone!
Janice Gipson I’m glad you learned something. I really enjoy teaching other people how to do stuff themselves.
The before and after photos are nice, I wish you could do this for random stones you collect, it's always interesting to see what they turn out to look like.
I have a video in the works right now showing some rocks from Lake Superior that I’m tumbling.
And I liked how you did the before and after picture to show the comparison it’s very nice good job 👏
Carson Frisch Thanks Carson!
I have a new appreciation for pudding rocks! Thanks!
Sue Erickson I found the crystals searching for diamonds in my youtup channel ➡️ cambaz cnl
Me, too.
Wow, you are a fantastic rock smith. Great work. I’ll be watching this one again! Upon closer inspection, your work really brought out the jaspelite or banded iron rock on the right!
My parents had a puddingstone a little smaller than this one that was cut in half. I inherited it when they died and I always thought it was just some slag conglomerate put together. I never knew it was a real rock (never learned of it in my Texas geology class years ago) until I saw you collecting them on another video. I had never heard of a petoskey stone either. You have amazing things at the Great Lakes we don't have in Southern Indiana!
I think it's fun that different places have different rocks. We are lucky here in Michigan to have a huge variety. The rocks near my house in Lake Huron are completely different than the rocks up in the U.P. If you get up to the Keweenaw Peninsula, there is a huge variety of rocks and minerals.
Very nice! Thank-you for another great video as always, you make a great teacher ☺️
Hi there! Great job!!! You made love to that pudding stone! You know every nook and crevice and corner by the time you got done with it. Impressive dedication!
You do get to know a rock pretty well by the end of that process.
@@MichiganRocks I knew you would agree! 🌞
Another Blast From The Past.Very Nice
Turned out beautiful! Great information too!
It really is amazing before and after. Love how you polish rocks. And thank you for telling us how you do that. Great information!
307 Wyoming 4E I love seeing before and after pictures. I don’t always remember to take the before pictures because I’m so excited to get started.
That process was impressive! Another great video... Thank you.
Gorgeous rock! You do great work. I enjoy your videos immensely.
I recently learned these conglomerate rocks are called puddingstone. I thank my jr high science teacher for encouraging my love of rocks.
The end product is really nice. Thanks for the helpful instruction.
As a junior high math teacher who is married to a junior high science teacher, it's nice to hear that you appreciated your teacher!
Gorgeous stone! I am so happy this video is out because I needed a tutorial for larger stones, I’m currently hand polishing a 90 lb stone that is the size of a basketball yet the shape of an oval, this tutorial is exactly what I needed!
I’m glad I could help!
Another awesome video. Appreciate the editing as well as the content. Thanks for sharing.
Wow! a beautiful stone and fine polish
I was looking for an art project to do with my kids. I am so glad I had found your channel !
I'm not sure this is a good kids project, but I have one on polishing a Petoskey stone by hand that might be.
I a have research how to polish large stones. Just stumbled across your video of pudding stones. I have accumulated several big and large for my property in southwest Michigan. Thank you for the how to no I can.
I'm glad I could help you out.
I’m not sure I’ve seen one of these with as much blue in it. Gorgeous!
I think those are probably more black than blue. It was a nice rock though.
That turned out beautifully!
What a make over! I do like polished rocks.
Mark Reetz I really enjoy the transformation too.
Turned out beautiful!!
Carolyn S I found the crystals searching for diamonds in my youtup channel ➡️ cambaz cnl
Ive never found a puddingstone but watched the crystal collectors channel and man are they pretty! New to collecting rocks
If you like puddingstones, I have a whole playlist about them. They're very popular to collect in Michigan. I've found little tiny ones all the way up to huge boulders.
th-cam.com/play/PLqNINgwEkm-JFqp4NngQF4UdEFP8pfF5B.html
This is just the information I’ve been looking for, thanks!
Cvx 2dog I glad i could help!
Wow! What a transformation!!
great! just today i was looking at similar sized rocks in my garden, wondering how i would be able to tumble them. now i know. i need to purchase one of those wet grinder -polisher and pads. fantastic. great post!
I haven’t been able to get them quite as shiny as tumbling, but the matrix is much better this way. When I tumble smaller ones, the matrix always gets quite pitted.
Gorgeous pudding stone!! Great video! Love this channel!
I love that you love it! Weeee!
Thanks for this video and your whole channel! I always know to go to Michigan Rocks for answers!
You're welcome, Nancy.
I was just talking about you and the pudding stones at work today🤣😁❤️
Fantastic, clear, concise presentation style. Thank you.
G E I found the crystals searching for diamonds in my youtup channel ➡️ cambaz cnl
It's so impressive to see the before and after of that rock. It's God's gift to mankind and you know how to bring out that shine. I love your little forest in your yard. Trees are amazing.
Thanks. Our whole street has wooded back yards. That’s one o the main reasons we bought a lot here. Lots of wildlife to see too.
Incredible piece!
Nahuel Britos I found the crystals searching for diamonds in my youtup channel ➡️ cambaz cnl
Pudding Rocks are really special to me, my dad collected them. When he died, my sister rescued a few of them. Now I know what I want to do with mine. Thank you, I found your videos by accident
Meaghan Larsen I’m glad you found me. I have a whole playlist on puddingstones if you’re interested. The small ones can be tumbled if you have any that size.
Michigan Rocks we are Michiganders and teachers too.
Meaghan Larsen cool!
That is beautiful! I never knew puddingstone could shine up like that. I can't wait to get to Michigan to hunt rocks- maybe I'll even find a puddingstone!
I hope you find one. They shine up pretty good. When I tumble them, the light colored matrix rock gets little pits in it, but the red jasper shines up great.
I just become a "Rockhound" in the last 3 years. I'm fascinated by the myriad of different types of rock i encountered when excavating my garden. Now, because I walk alot, i find rocks all over NYC. So oftentimes I travel with a butter knife and a plastic bag. People look at me like im crazy, but they'll never get to see the fruits of my labour. GREAT JOB with that rock, its gorgeous!!
What's the butter knife for? Prying them out of the ground?
@@MichiganRocks Yes. I only collect the ones I see loose or partially buried, when outside in my neighborhood.
@@MichiganRocks In all actuality the butter knife is to defend my newly found bounty from 'Rock Pirates'. They're everywhere!
@@MADGUNSMONSTER Yikes!
Wow looks amazing after your work on it! Loved watching the process. I have a lovely slice of pudding stone that looks like its had some polishing but not as much as that!
I have never polished a slab. I should do that when it warms up. Seems like it would be pretty easy since I wouldn't have to keep track of what I had done and what I hadn't.
Great job! Looks great!
WOW, that is so cool - wish I could get my hubby into this hobby... I know those stones would look gorgeous, too! Thank you!
Why your hubby? Why not you?
@@MichiganRocks I know - my hands are too shot, I'm afraid! So I'll just enjoy the mysteries being revealed! It is fascinating.
Small Wonda oh, sorry that you’re not able to do it yourself. Good luck working on your husband.
Mr A!! My junior high math teacher! I just stumbled on your video on accident. My mom collects these stones and I’v wanted to polish one or have someone do it, maybe ill look you up sometime. As far as math, well I was never good at it, and even in college, I had to go to a math tutor everyday after school to help me through it, and eventually I got my degree. Now I gotta watch more of your videos. You ‘rock’!
I'm not sure who you are, but hi! Hopefully I didn't shock you too much when you ran across me with no warning. Thanks for letting me know you found me.
FANTASTIC. Really great!
Nicely done!
Excellent vid - thank you for posting
You're welcome, Mr. Lewis.
Great vid, subbed. I've just recently discovered my interest in geology and being a Michigander myself I think I'm in the right spot, I have three puddingstone that are about three times the size of the one you just polished, two more about twice the size and one about the same and I've been looking how to polish all of them up, thanks for posting the vid, looks like I've got some work ahead of me!

Wow , amazing job
Good to see you on Pinterest Rob...love your videos! I learn so much from you and your wife and neighbor. Thanks and keep them coming.
I didn't know I was on Pinterest. I think someone else probably put a video of mine there.
@@MichiganRocks yessir! I look up various rock specimens here, at times, and I ran into you sanding and polishing your friends Pudding Stone. Maybe someone placed it here. Never theless, it was great seeing your videos here.
Wow, so gorgeous!
Congratulations, this video is amazing, good luck ❤❤
Crazy talented
You're a great teacher. Great video.
Thanks, I'm glad you learned something.
Thanks for all of your amazing videos that have taught me so much over the years and have contributed to one of my favorite hobbies. Your videos were a wealth of information when I started tumbling a few years back and they continue to be today as I've just stumbled upon this video. I recently found a Petoskey stone about half the size of your pudding stone and was going to try out this process with polishing it. Keep doing the amazing work that you do! All the best!
Wow, thanks for the tip! I'm glad my videos have been helpful. Have you seen my videos on polishing Petoskey stones? I did a big one with a drum sander on an electric drill. It wasn't made for polishing wet, so I wore out several drums while doing it, but it got me through the first stage. After that I polished it by hand. That's a lot cheaper than buying the machine I used in this video. Here's my video on hand polishing a Petoskey stone:
th-cam.com/video/sjImNrwR9As/w-d-xo.html
@@MichiganRocks Thanks for the advice, I've handpolished a few smaller Petoskeys using that video actually! I really lucked out and found that makita wet stone polisher on facebook marketplace new in box for a price too good to be true so really been looking forward to getting it dirty. I'm a bit hesitant to put an angle grinder to the Petoskey for the first stage so I may try your drum sander technique or go at it with some 30 grit pads on the wet Makita until I'm happy with the shape. Either way it will be a fun learning lesson!
@@foulout If you already have a Makita wet grinder, just use that. It's made for water and it will work well.
That rock was really nice. Trying to talk my siblings into a trip to Michigan 😉
It sure was nice. They're not all that good.
A beautiful pudding stone!
That is totally amazing ! Thanks for sharing :)
Chocolate Cherry Coins you’re welcome!
Glad to see you're wearing a respirator! ;) Looks great.
I like how my lungs work. I'd like to keep them that way.
Excellent video 👍
There was a time when I'd have rolled up my sleeves and done that but I don't have the strength now so I guess I'll just have to find one to buy :) You did a great job :)
Mary-Anne Swanson thanks. If you’re just doing one, it wouldn’t be worth investing in the equipment.
Etsy and other online sites have some gorgeous specimens
You did a beautiful job on the big rock.
Thanks Thomas!
That turned out perfect!!
I thought it looked pretty good.
Thank you! I’m learning
I just liked and sub this is a great place to learn for me just starting the rock hounding thing in Upper michigan
that's gorgeous!
This is truly impressive!!!
Thanks!
Nice work
Beautiful
Really is incredible how it goes from beast to beauty
That's why I keep polishing rocks. It's the transformation that I enjoy.
Essa máquina de poli q tem a lixa já saí água junto. Bem pratica. 👍 Interessante o processo de polimento da pedra. E um processo q leva tempo mais o resultado ficar vale a pena.
Wow.. hope I find some on my trip..,👍👍👍
Good luck!
Awesome!
Did a great job 👍🏼😄
Thanks, Victor!
Woah man! What a beauty! This was really helpful bud. I’m working on those littler ones yesterday and today and it’s really so much fun but also kinda mesmerising doing it. Learning a bunch from you dude. Thank you so much!!!
Rookie Rockhounding this is what I think you should do with that big one you dug up and dragged home.
Michigan Rocks
Yeah I’m hoping to get some of the grinder cup things and then try them out on that biggy 😉 hopefully ha! Have a great weekend mate!
Rookie Rockhounding good luck!
Michigan Rocks
That rookie gets everywhere, always poaching ideas and getting free advice.
BTW, that's just my sense of humour and I never ever write anything derogatory about my Buddy the rookie.
Symon Sheppard yeah, what a jerk, coming here and complimenting me all the time!
great job
Thank you.
Good job, no matter how you do it.
Awesome job sweet knowledge thank u
I love how the thumbnail makes me think it's a small stone. Then I see you holding it, and my mind is blown
Yes, I guess I should have put something in the picture for a size reference.
@@MichiganRocks a banana for scale, still that was an amazing rock. Very beautiful. Excellent job polishing it
So awesome thank you so much , I live in Indiana my dad plowed one up about 35 yr ago it's huge like 2'x11/2' haven't measured but some where give or take , he brought it up to the house and been wanting to polish it , now I can't wait , going to start it immediately now I know how lot of red jasper and lots of other stones haven't seen the bottom ever so turning it over to see best side , I herd Indiana is pretty rare for this , Mich, Canada Europe, China ect are the usual spots so cool it could be 2.3 billion yr old , ice age stuff don't know how they can tell in billions of yr ?? But definitely some ice age , pretty fascinating, so Thank you so much .
Puddingstones found in China or Europe would be a different kind of puddingstone. These are only found in Ontario, Michigan, and a couple other states, like Indiana, for example. They come from a spot just north of Michigan in Ontario.
Nice! Thank you for this tutorial. We have a monster huge Petoskey stone to polish!
Petoskey Stone is much softer than puddingstone, so the work will go much quicker. I did a pretty big one that I found in a quarry. The rock wasn't very good quality, but it shined up by this method pretty well.
Thank you! I’ll look up if you did a video on the polishing of it. My brother who’s passed found it and gave it to my Mom many years ago. She’s 92, so we’ll want to polish it this winter. Chuck said he almost died getting it :-)
Patty W P Schoonbeck you can start it just like I did in this video. I do have a Petoskey stone polishing video and you could finish up the last step or two like I did in that video.
that's awesome!!
Very nice thank you
nice job . Thanks for sharing on youtube
It's beautiful!
Yeah, it turned out nice.
that is so cool
good job
Wow so cool
Thanks!
Hi I'm new here I have also like this rocks I like to collect a nice stone
We were doing garage sales in Michigan and hoping we'd find somebody who had large rocks to put around our campfire pit. We turned into one driveway and my wife said "look at all the big rocks!" I didn't even see them. We purchased some items at the sale and then my wife asked if the rocks were for sale. The lady said :"Oh, take all you want." The rocks were scattered in their vacant lot across the street. The sizes ranged from 1 to maybe as much as 50 lbs. I started throwing the 5 to 10 lb rocks into my truck and spotted a near perfect puddingstone that was about 30 lbs. The lady said "Oh, I want to keep that one." I continue to load the other rocks and found some less impressive puddinstones which she said we could have. Also we got about a dozen very large Petoskey stones! The biggest I've ever seen. Some maybe 5 or 6 lbs! They just found these rocks on their property and piled them up. I sure was glad my wife saw them! Now I have to build a giant rock tumbler. Looking for plans is how I found your video. Thanks
What a great find! Petoskey stones are really hard to tumble, so you might want to do them by another method. Here are a few ideas:

Nice job, it really turned out pretty. Now I'm off to see if you have a video of cutting one up ... I hear they are stunning in slices. I want to see that.
Anita Mitchell this coming Friday, you’ll like the video then.
I’m going to try to do this!
Go for it! It’s not difficult.
I wish we lived closer to one another. I have some massive pieces of jasper and a large stump of petrified wood my grandfather found in AZ back in the early 1900s, which has been passed down through the family. I have always wanted to polish that piece, but I'm no longer able to handle that type of equipment any longer. If it is large and has a relatively flat top, (like the pet wood stump has) a friend of mine told me to round the very top edge off about a quarter to a half inch, so that more light gets through the top clear top to brighten the inside colors. It was from the petrified forest area many moons ago. I plan on soaking it soon to open up the colors, but I'm always hesitant to do that because the family member it goes to next likes rocks as they were found and so do I. The jasper pieces start at 5 pounds and go up past 70 lbs. I about killed myself getting that one up out of the cliff and that was years ago. One larger one is egg shaped and relatively smooth, so it would be easier to polish, but it is a lot of work. I've done this before, but only a few times and you did an amazing job on that stone. WOW!!! If you open a float agate by cutting it, or with a flat lap, slightly round off the edges to prevent cracks and chips and use a smoother grit. It does make a difference when using a cab maker, but only with flat ends. The larger the piece, the more material you round off. Even with medium to large size agates it makes a difference with the light that comes through and protects the edges. Again, beautiful work.
I'll be doing another one of these this summer. A lady at church asked me to polish a puddingstone just a little smaller than this one, but also nicer. It has a story with it an she agreed to tell it for my video. We're trading polishing for video content. I think everyone will go home happy.
Very nice
muy buen trabajo
I was surprised you weren't surrounded by a cloud of mosquitos in the first grinding step. I think your can of OFF! is a vital tool in this process. :-)
It definitely is. There’s a swamp a little farther back in my yard. The mosquitos are awful.
Mounted buffing wheels are the way to go.
Love!!
NICE
