Here are the steps I took to polish this:
I started with my normal, dry angle grinder with a diamond cup wheel. The cup wheel is 50/60 grit. I followed this up with a 16 grit silicon carbide wheel.
Next I moved to a Makita electronic stone polisher. This has a soft backer, so the pads can flex to the shape of the rock. The grits are as follows:
30 grit
50 grit
100 grit
200 grit
400 grit
800 grit
1500 grit
3000 grit
6000 grit
8000 grit

If you like my rock hunting videos, I think you'll really like Thomas's channel. th-cam.com/video/TjfUqASineg/w-d-xo.html
Thomas's channel is great!
You cracked me up with the safety gear switches. The rock was nice. It almost looked wood grain when you were done. I’ll go check out Thomas’s channel now.
Thomas and I both thought it looked like wood grain too. Nice rock.
Very funny editing, made me laugh with your "going to the grocery store" comment lolol great vid! Thanks guys, alot of fun😁really cool rock, it turned out great
I was hoping that my little joke would be audible through the mask.
Ya, it was great! lol
The grocery store joke cracked me up too.
You did a good thing, brother! As if I needed another reason to like your channel. Great collaboration, and great results!
Thanks, Cristian!
That is a beautiful piece of jasper, even unpolihed.
I agree. I liked it both ways.
Nice piece, polished great.
I have a yard full of untouched rocks and fossils, can't resist bringing them home (for a few decades or so, lol)
It's delightful when it rains :)
I can see how that could happen!
I like those natural imperfections in rocks. It is beautiful!
@Dawn Hill I agree ! Completely !
'And now you're ready to go to the grocery store '
I got a good chuckle outta that 😆
I'm glad you're amused.
Looks like a big hunk of petrified wood. 😍
It does, doesn't it?
Beautiful job...I've started circling the areas that need more care. Thanks for the little tidbit. It helps immensely. I've watched Thomas's TH-cam videos.
I like Thomas. He stayed here for a few days to rock hunt with me.
Turned out very well! At 2:06-2:12, the rock looked like the profile of a dog. 👍 Nice video Rob.
It does! I almost never notice things like that.
Love the woodgrain effect.
Yeah, that's cool, isn't it?
Nice job on Thomas's beautiful rock! I really like his channel too. You gave me a good idea with the polishing table. Having pieces of boards screwed on to help keep rock from moving around while you working on it.
Yes, Thomas has a good channel and it all stared with this rock.
I really like you are helping others... respect
Thomas got a shiny rock, I got a video. Everyone wins.
Great job on this rock. What a beautiful specimen. 😍. Your video had me laughing. Very much enjoyed. 🤩
I'm glad you liked it, Stacey.
Wow, very cool transformation
You are awesome brother what a great project and a wonderful thing to do for a young man starting a new channel. Thanks for setting such a good example. 👍🎯💯🔥😎☮️🌎♾️❤️♻️🙏🤳
I just wanted to see the rock up close!
This is the best thing I've seen so far this week. Super satisfying. Thanks!! I do love jasper....
I just hope it's not the only thing you've watched this week!
A rock handoff that spanned Wisconsin! #RockOn
That was Thomas's idea. I think it turned out pretty well.
Gorgeous shine..... expertise...perfected BEAUTY......SOooo GOOD🤗
Thanks, Lindalee!
Your large puddingstone and large unakite polishing vids are my favorite videos you've uploaded. Just yesterday I was hoping you'd be uploading another large rock polishing video soon and then you go and upload this today! Awesome!
I really need to do some more large rock tumbling videos. That unakite video was really popular. I was thinking of doing a large crazy lace agate.
Beautiful Jasper and polishing work
Beautiful jasper!
Loved the special effects!
Fancy, huh?
Nice stone...GREAT results!
What an awesome finish.
Nice job, what a great piece of jasper, thanks for sharing
Thanks, and you're welcome!
Clever hand off! Always enjoy the creativity and personality you bring to your channel!
That was Thomas's idea, so he gets all the credit. I liked it too.
I love how I can tell just how much fun you have making these.
Weeeee!
Amazing transformation!
Thank you so much Rob! It looks absolutely amazing. It totally made it worth carrying around all day!!
You’re welcome. I just found this message in my spam folder. I can’t figure out why TH-cam thought it was spam though.
It polished up nicely. Great job! Be happy, safe and stay healthy 😷⚒
Yeah, it turned out pretty good.
What a great job you did on polishing the rock..... He will be so pleased with it 💕💕👍
Thanks, he was happy with it.
Fun video. And the rock is so pretty! Love the colors and patterns and textures and the whole sculptural look. Super nice of you to help the kid out. Not just doing it but showing how. Thank you!
He got a polished rock out of the deal and I got a video. Everyone wins!
That is such a beautiful rock 😍 love the way it turned out.
It sure is shinier than when I got it.
“I feel like I’m ready to go to the grocery store now,” - too funny Rob! Nice work on the jasper. I know how long it takes. An 8 min video doesn’t do any justice. You spent a lot of time on that big rock.
Yep, these take hours and the video stuff makes it take a lot longer. I only do a couple of these a summer because I don't want to annoy my neighbors too much with the noise. So far, no one has complained.
What a drastic change
Great job, Rob. Nice looking jasper.
Gorgeous specimen. Nice Work.
You guys are so awesome.... I just love the partnership! LOVE the hand off!
The hand off was Thomas’s idea. I liked it too.
That was fun! Enjoyed the Economics lesson the most, “Get some new pads.”
Funny thing is, I have some new coarse pads and I just didn't use them. Next time.
It's beautiful, Rob
For a second I was sure I clicked on the wrong video 😆 great content as usual 👌
I thought that would be a fun way to start out, with a little surprise.
What a nice rock indeed! Deep red colours and the bold lines throughout really set it off. Good collab here!
It was a keeper for sure.
Wow you're becoming quite the actor! 😆
Well that's a stretch.
It’s beautiful. Great job .
Thanks, Denise!
These videos to shine rocks with sanding and buffers are so interesting. Tumbling is fun but it takes so long. You can shine up a big piece of rock in one day by more intense processes. This rock turned out so well and I'm sure Thomas is going to be thrilled. We always learn so much watching your videos. I belong to a Michigan Rockhounding group on facebook and one member mentioned she's unable to go to most beaches as she's in a wheelchair. I suggested she go to youtube and watch your videos as they are such fun. One guy commented that he liked your videos as well and he thinks of you like the Bob Ross of rockhounding!
I think I read that comment about me being the Bob Ross of rockhounding. Someone else said that too. I'm not quite sure how to take that.
I have gotten quite a few comments from people who are no longer able to get out on beaches to hunt and live vicariously through my videos. I like that they're being used that way.
I'd much rather tumble rocks than polish them this way. It's not very exciting work. I also worry about bothering the neighbors with all the grinder noises. It's true that they only take a day instead of months, but with the tumbler, I don't spend too much time doing much, and my back doesn't hurt when it's over.
Great work on the polish, also very cool rock!
Awesome video, i like the intro, it was different and unique. The jasper looked amazing at the end! All those bands were really cool. 😍🥰😇👍🏻👍🏻👍🏻
I thought Thomas did a good job. It was a fun project to do with someone else.
@@MichiganRocks It turned out AMAZING! 😍🥰😇👍🏻👍🏻👍🏻😍🥰😇👍🏻👍🏻👍🏻
That was very cool! Thanks for sharing....
Glad you enjoyed it, Dan!
Awesome video sweet looking rock outcome fantastic awesome job thank u
Thanks!
Beautiful job wow !
Awesome job!!!
Thanks!
Looking good so far
Hello, hello Michigan Rocks and 99 Rockhounding, This is a class A video from start to finish. I love the rock handoff, so cool of an idea. That jasper has a lot going on in it, especially the many close lines side that resembles wood grain. Once again, MR has shared an enormously valuable lapidary video using an angle grinder, blocks of wood on the tabletop, and the Makita electronic stone polisher. I'd have to buy those tools but it would increase the possibilities to polishing some larger stones that won't tumble well. Thanks for sharing a great video.
I'm glad you enjoyed the video, Doug. The rock hand off at the beginning was all Thomas's idea. I think it worked out well.
I think the, as you call them soft areas, ad character to it. Looks great. Thank you for sharing.
They do show a contrast between them and the shiny parts.
@@MichiganRocks I started following Thomas as well. Looks interesting.
I love that you and @AgateDad are mentoring a young rock hound! The collaboration turned out beautifully too! 💯✅
Thomas doesn't seem to need a lot of mentoring. I think he has this stuff pretty well figured out.
Love the intro! Dude is awesome
Check out his latest video, it's really good.
Beautiful stone 😊
This was a great collab. Fun and educational! But of course, you are a teacher 😊
Good luck!
Great job
The swirl's and lines through the stone looks like tree rings and grain pattern very cool rock,nice job Rob...
Yes, it does look like wood in some places. It's a great rock.
Turned out really nice.
Thanks!
I was super confused at the beginning of this video. But, man, that's a pretty rock!
I can understand why.
Wow that would look amazing as a table top!
It would be a very small table though.
@@MichiganRocks sure if you only use the one rock.
I love It’s so smooth and shiny cool
That was the objective. Mission accomplished.
Damn you did a awsome job. Looks amazing man!!!!
Thanks, Ivan!
2:29 "I feel like I'm ready to go to the grocery store". Ha! That was funny right there, you cracked me up. :)
That turned out really nicem
Nice
Yah!!..quit being so cheap Rob!!!..jk!..what a great video!!..I like how you show each step,so that we get to see the transformation gradually. I know this project took a considerable amount of time,so I appreciate you doing it.. Thomas is lucky to have you do this for him!..I'm going to jump on over to his channel now...have a great weekend!
I saw your comment over on his channel. I think you'll like it. I sure like what I have seen so far.
@@MichiganRocks he's good!!..amazing jasper and agate!!..guys a natural!..and he knows his rock terminology!..awesome!
Nice job! That is much harder than it looks. I've done some larger pieces of petrified wood and also jasper, using similar techniques and you handled the undercutting a LOT better than I thought it would come out (sometimes you don't know when it will end, or get worse). Beautiful lines and layers throughout the jasper and the quartz is a very nice touch.
I think it turned out about as well as could be expected. I knew it wouldn't be perfect so I tried to quit while I was ahead.
Fantastic
Nice work!
Thanks!
Nice job!
Thanks.
Very cool collaboration!
We had fun doing this together.
@@MichiganRocks cool! :)
Great collaboration! We vacay in northern MN so I'll be sure to go check out Thomas too!! If I watch enough of these videos, I might just plug in the tumbler and see what I can do too.
You have a tumbler and it's not plugged in???
@@MichiganRocks bwah ha ha ha!! Right? I need to get all the supplies!
GREAT VIDEO HAHA the grocery store :)
That's just what came to mind for some reason.
God I love jasper!
Very cool collaboration.
That was the start of Thomas's channel and our friendship. I've been to Minnesota twice to hunt with Thomas and he's been here once.
@MichiganRocks Very cool. I'm an in-betweener, good ole Wisconsin. I just started collecting and tumbling last year. Now, my whole family is a bunch of geology nerds. I've learned a great deal from your videos on how to tumble. You have also helped me identify a lot of what my wife and I collected in MI this summer. We even got to go to Lindberg and sons to collect Kona Dolomite. Thank you for all the great videos and advice!
@@whygowegabusch120 Can you believe how cheap Kona is when you get it at the source?
@MichiganRocks It is crazy! We got lucky that the Ishpeming gem and mineral show was happening while we were on our trip, so we went on their field trip to the quarry. We definitely plan on going back.
Nice stones
Word has is, Thomas is still stood in the Minnesota river waiting for Rob to hand his rock back.
He's not waiting anymore, because I did hand it back, in person.
Good job fromlao
I've been eyeballing grinders. I will check out your Amazon Store. Thanks.
That wet grinder is kind of expensive, but it has worked well for me.
Настоящий мастер своего дела. 👍👍👍
Спасибо!
Word of advice for those silicon carbide grinding stones. DO NOT EVER get them wet or drop them. If either happens throw them away. The water will rust the hub and cause a hairline fracture. And dropping will also fracture it. Also I NEVER spin any of them over 4,000 rpm.
They also work great to dress diamond blades. Get both spinning and grind the leading edge of the blade with the wheel. It will make the blade like new again!
Thanks for the tips, Aaron.
Subbed to your friends new channel😃
Thanks. He's off to a good start.
UAU! QUE LINDO!!!
whatta beauty , nice work Rob......I hope to send you something from Ca someday
Robert J.
I almost always turn down offers of rocks. I'd never be able to do something with all of them. It's really nice that a lot of people offer though.
@@MichiganRocks yeah well there ya go then
wow!!!
Cracks in rocks seem to eat up the flexible diamond sanding pads. I think the cracks grab and rip off bits of the rubbery matrix material that holds the diamonds. A lighter touch can help, but it takes long enough when applying pressure. A firmer pad holder also seems to help them last a long longer, although I understand the benefit of the softer, more flexible pad holder. I think that's why you see them wear the way yours did -- with the outside being worn out before the inside. With a soft pad holder the outside is particularly flexible, and when the disc bends to get into a cracks it rips off the rubbery material on the face of the disc even more quickly.
I got the soft backer when I was doing stone bowls. It really helps to get in the concave part better. I also tend to use the outside of the wheel more, so that's my fault. You're probably right about the cracks pulling off those little rubber bits. I have gone through more of the 30 grit pads just like I go through more coarse grit in the tumbler. The other ones last quite awhile.
Rob, have you thought about epoxy filling the depressions, and re-polishing?
Nope. That might be a good idea, but I haven't tried anything like that.
I like those depressions ! Finished it looks like a miniature cliff with little cave dwellings in the side .. I think they add to the charm .. : ]
😎👍
Excelente la piedra 👍 hola cómo están saludo
Heck. Grocery store? You should have received invite to 44’s birthday bash.
I'm just getting into this. When I attempt to polish a rough jasper or pet wood, I can never get the surfaces completely polished. most of it is perfect, but there's what seems to be small, very shollow indents that don't get polished. I use a dremel but smaller rocks. 50,80,120,240,380,480,600,800,1000,2000 grit.
maybe it's too hot, or I'm unaware just unaware of the correct procedure lol.
ty for reading lol✌🏽
I have never polished a rock with a Dremel, so if that's part of the problem, I can't really help you. I do know that some rocks have parts that are softer than other parts. Soft rocks can be hard to polish. You might just be working with rocks of varying hardness.
Another problem might be that you're not spending enough time with the 50 grit and leaving behind some spots that are slightly concave. Concave areas are going to be either missed by the polishing pads, or will get less pressure if they're only slightly indented.
@@MichiganRocks ty that is helpful
That sure looks like a piece of mahogany wood !!! I’ve never had a good understanding of how to identify Jasper. Maybe sometime you could give a demonstration. Is red the only kind that’s found in Lake Huron and Michigan?
I'm not the guy to help you with that. I just know that it's red and has conchoidal fracturing. I read up on the difference between jasper and chert once and it is very confusing. A big part of the problem is that geologists and lapidaries use different vocabulary. This one was banded iron formation, I think. That's another good way for me to identify it. As far as I know, we only have red jasper in Michigan, but I could be totally wrong about that.
Silly question I’m sure, but on the rotator tumblers, does it make any difference at all to reverse the tumbler direction mid point of the tumble?
I don't think that's necessary. I have never done that.
Is it possible to polish even more (after the 8k) with a buffing wheel an micro aluminum polish?
Rock looks so much like wood.
I'm sure that it would be possible to get a better shine. I don't really have a big buffing wheel to try it.
Hi Rob. May I ask....I’ve got a 4 1/2 day time frame to hunt. Coming from Ohio. Did superior last year. Would u be so kind to recommend a destination given the workable travel time that I have? Very grateful and hooked on your channel! Sandra
I think I need to get the 6000 and 8000 pads but they are proving to be a bit elusive. Be perfect for the obsidian free forms.
I don’t know if they’re available in New Zealand, but they’re in my Amazon storefront.
