I have made these as well and know this as folded gniess. It is easy to find absolutely beautiful raw pieces usually in creek boulders. Gnice piece you have made.
Safety and protection is good. Respirator and glasses is a must for such work, ear - maybe not that necessary for grinder, that's not so much noise to dammage hearing, but if you do have the headphones anyway they won't make things worse. The gloves hover, are strongly not recommended near devices that spin. If you touch something with a naked finger you may get a scratch at most (you can of course cut off the finger but lets be honest gloves don't protect from that either). But if you touch a spinning part with glove there's a chance that it'll got caught and will pull your hand into a meat grinder. I had a situation at work when one woman was wearing gloves near the machine with spinning shafts and gears, and the gear bited the glove and pulled the finger in. Luckily that machine was spinning quite slow, there was another colleague nearby that stopped it almost immediately, called for help and we partly disassembled the mechanism in about a minute to pull the hand out. And luckily there was only a broken bone that was possible to heal. But if then machine was stopped 5 seconds later, that woman could easily lose an arm or worse. So remember, if something spins - gloves, sleeves, baggy clothes, long hair and etc is a huge no no
@@nemorianderson Almost all angle grinders are above 80 dB. At that level, you need to wear hearing protection to avoid permanent hearing damage. If you care about your hearing, you should always use ear protection with any tools over 80 dB.
@ritterlost8424 I guess it's also depends on the environment you using it, and for how long. Like if you need to cut a lot of pieces in a tight room then yeah, headphones are a good idea. If its 20 seconds of work on the open space, than noise damage is negligible. I mean sure, if it do affect and you work with them a lot protection is needed. But on the other hand a lot of things outside are also louder than 80 db. Wouldn't you wear the headphones while crossing the road cause there's a truck ot a motorcycle passing nearby? As for me i often use power tools and sometimes worked with mills and other big machines, and can't say that I'm deaf now. However there were times that i visited machine rooms that were extremely loud. I'm not sure how many db it was, just so loud that you won't hear another person screaming at your ear. And first time I made a dumb mistake walking there for few minutes without headphones cause i forgot them and thought nah, in and out, I'll be ok. Damn my ears hurt there, and also i heard ringing after that for about an hour. So yeah, with those kind of noise not using headphones is suicidal)
Love the way you cut it by hand it's so quick. Usually I cut about 32 cuts in the gig which takes ages. Then I grind before putting it in the machine. I have used both steel and plastic cups with 80 silicon carbide grit when the diamond cups are too rough. I was surprised how long the plastic cups lasted with the grit. Great video.
I bet it would look really nice as well if you dipped it in thin resin and then polish it so the resin would fill some of the pores. Great job, looks beautiful.
The beginning of the video is the classic "oh, a stone that looks nice" that seems to be absolutely ingrained in humans. Picking up stones you think look neat, probably older than history, and even Homo Sapiens. :D
Gneiss used to be granite. It got folded and smeared under high heat and pressure deep underground by tectonic movements and metamorphized. Then everything above it was eroded away or scraped off by glaciers. The black parts are mica, which you can almost scrape off with your fingernails. The red stuff is feldspar, and the white is quartz. That looks exactly like the gneiss we have everywhere here, which was brought from the Canadian Shield by glaciers. The granite north of here is also pink.
Reminds me that some years ago when visiting a beach in Devon that was composed of white quartz stones, I discovered 3 pebbles, the size and shape of eggs. I took them home and put them on the rockery. The crows stole all 3 obviously mistakingly them for real eggs.😢
I've thought about making a stone ball by the pecking method (hitting it with another stone until its a round ball). I won't go any further than thinking about it as it's a huge amount of work and time, and a lot of noise lol
Have you ever considered adding a fourth motor to your sphere grinder, to put the bits into a tetrahedron array? I guess that keeping the water out of the motors would be a bigger problem with that, though.
@@pebble-ology1845 Since I asked you this question, I have considered how I might accomplish a 4 motor grinder, and have concluded that, yeah, it gets a lot more than 1/3rd more complicated.
Ich benutze für das erste schleifen Bohrkronen. Das geht viel schneller als nur mit den Pads. Ab und zu habe ich auch das Problem, dass einige Kugeln an einer oder zwei Stellen Spuren des schneidens zu sehen sind. Ich fahre dann vorsichtig die ganze Kugel noch einmal mit dem Sägeblatt ab. Also ich schneide nicht, sondern versuche nur in etwas die Tiefe des Schaden zu erreichen. Wenn man dann neu anfängt zu schleifen, ist fast immer der Fehler weg. Wenn man versucht den Fehler durch schleifen der ganzen Kugel zu beheben, dauert es viel zu lange. Aber wie gesagt, ich würde es zuerst mit Bohrkronen versuchen. Es gibt auch kleinere für Steckdosen.
Please dont wear gloves with a grinder. what can happen is the gloves will be pulled into the grinding disc and it might tear your hole skin off with nerves attached. which is impossible to reattach at the hospital. if you lose a finger you can at least get it reattached
You don't wear gloves when working with grinder. You do, however, fix your bench in place so it doesn't wiggle and keep all the cords and tubes away from blades. Nice balls of stone.
Beautiful, Gneiss is metamorphic granite. I can send you tons of cool rocks to cut if you can cut a few for me 😊. I'm a professional amateur geologist and professional meteorite hunter and collector. I buy most meteorites because hard to find in non desert areas 😅
I have a sphere machine that I built from your previous videos. Thanks for that. My current project is a hunk of marble that is shorter on one diameter than on the orthogonal two others. The 50 grit cups are not taking rock off and I'd like more aggressive action. Where did you get the grinding parts of your aggressive cups, and do you have any words of wisdom about attaching them to the cups?
@@kennethgeoheganrogichms4349 I buy the pads on Amazon. I’ve used 50 grit for most stones but for anything of a hardness of a quartz or jasper I use a 30 grit. I super glue sections of the pads to the grinding cups. I would experiment with your tension to get a better grind.
I would be interested in making a sphere machine of my own. Can you upload a plan? In particular, I'd like to know what you used to make the pads. Thanks!
Hmmm! I was taught ot to wear gloves when operating any power tools, and especially any rotary tools. But hey, the rest is probably fine. And hey... You can never make everyone happy. ;-)
If your hands close enough to get caught in an angle grinder you are doing it wrong. I urge people who want to use a grinder to seek out help from someone who uses one lots (welders) and can show you how to use them properly. I have seen many many injuries from improper use. Wear your gloves.
@@trevorgoode4219 In Germany, it’s forbidden to wear gloves near belt grinders, and OSHA doesn’t approve of it either. If you're working close to the belt, don’t wear gloves!
@@trevorgoode4219 I would rather have skinned fingers, than torn up hands, or be dragged into reciprocating machinery, never wear gloves with rotary tools! No ties, rings, floppy clothing, or other dangerous 'fashion' accessories!
I was always taught no jewlery or anything that can get caught. I remember my class in trade school. Dude got his wedding ring caught in the lathe. We were finding pieces 2 years after.
Gloves and high speed rotary tools are not a fun combination. What could be a nasty gouge without gloves could be a hand crushed and twisted if the gloved hand is caught in fast moving parts.
Nice video. Safety is relative to the user. I predict you will roll this forth and fill the whole world with stone balls for the safety police to find.
Surprisingly thoughtful to bring a replacement stone!
Otherwise it’s theft
Definitely did turn out to be pretty gneiss.
L.O.L.
Im glad the algorithm brought me here, Cool vid. Something very intrinsic and pleasing about making a rock sphere.

Thanks!
Glad you enjoyed it.
The "sphere machine" is just wonderful!
Bravo! Such a well presented video about a means to make something so beautiful. We had no idea there was a sphere processing machine. Best of luck!
Maybe a bit less talk but beautiful stone and great video you got my sub
The ball machine is pretty awesome.
I can't believe this channel hasn't blown up yet. Those stone-heads would absolutely gobble this up
Had that same thought. Pebble-Ology are you on any other social media? Instagram ? I’d love to check out more photos. Excellent video.
this is such a ruidonculous contraption and it never ceases to amaze me how well it works
looks like space. Great job Man. And I never knew atall how to do this. Thanks.
Looks really gneiss when you're done.
You win. Congratulations.
Beautiful. I remember finding natural spheres along the water falls in yosemite as a kid.
Lovely job. It came out very cool.
That's some gneiss schist.

As a woodworker, I was concerned to see you working with your hands so close to that cutting wheel.
@@martys9972 a diamond blade is nothing like a wood cutting blade.
sweet job
Nice
I bet it would look really nice as well if you dipped it in thin resin and then polish it so the resin would fill some of the pores. Great job, looks beautiful.
I have thought of that. Maybe in the future I can use a lower grade stone that has issues and experiment with resin. Thanks.
Gneiss and easy does it, does it every time 🎵
That sphere grinder looks like something they invented in Mesopotamia, 4000 years ago and nobody’s improved on it because it can’t be improved
Pretty gneiss result from the aggressive cups.
The Indiana Jones routine of dealing the rock out for another one lol. Very sneaky.
Thats a very gneiss rock.
The respirator is a good idea, however wearing gloves with an angle grinder is dangerous.
YES, LEATHER GLOVES OR NO GLOVES.
What a Nancy. Not dangerous at all if you know anything about using tools.
Yes
Cool machine. :)

You’re a fun kind of weird. Keep on keeping on.
Looks great, very much like a gaseous planet with those bands.
Careful wearing angles around that glove grinder though.

For a second there I was worried you were stealing but good on you doing a fair trade, rock for rock of similar size.
Nice!

Gneiss? More like nice. Ok bad puns aside, that's really cool, glad youtube recommended this channel to me
Make that bad spot a flat spot so it can sit on a shelf or a table and not try to roll away like the meatball from the kids song.
Nothing like a hunk of gneiss
I only came here for the gneiss comments
yeah more bridge or railroad or tunnel will be amazing sir
In German we pronounce the g in Gneiss. I believe that’s the origin of the word. Very common metamorphic rock.
Looks like diorite, volcanic mix of bassalt and quartz that cooled over a long period of time
I strongly recommend you to buy some UV light and see if some stones after polishing have some interesting effect :)
That's a great idea.
That's a meters rock from space .. thanks Suze
God bless the YT algorithm 👍❤️

I'm in Colorado and make custom crystal ball stands called hand stands which started being modeled after my right hand holding my labradorite sphere
I have seen things like that. It would be fun to see one of your stands holding one of my spheres.
The rock so nice they named it gneiss.

Gneiss!
This was very interesting. I collect spheres. The grinding part was pretty slick. Are the cutting blades diamond or just steel?
diamond. I'm thinking of creating a store for my stones. Please let me know if it would be something that interests you.
Please dont wear gloves with a grinder. what can happen is the gloves will be pulled into the grinding disc and it might tear your hole skin off with nerves attached. which is impossible to reattach at the hospital. if you lose a finger you can at least get it reattached
BTW gneiss is a German word and the g is not silent. Do with that information what you want 😁.
That's a high grade metamorphic rock.

Utah, USA
OMG!! You need to wear a jock strap for improved safety!!!
That seems to be the most unsafe operation in North America. I’m shocked you still have thumbs, but the finished product is fire

Hopefully you do something with them. Good luck.
