This is like a time machine to the early days of youtube. People doing what they're interested in, and sharing it with the world. No ads, no sponsors, no "like and subscribe".
It’s been my goal to make videos that I would want to watch. I’m glad some people seem to enjoy them because I just love making them! Thanks for watching!
sucks that this a rarity for your youtube feed. most engineering or crafting videos are still like this. most dont even have dialogue. even the high subcount guys. stuff like "maker b" or "shurap". even "AvE". even "adam savages tested" feels like old youtube. honestly a shame you only see ad infested garbage on youtube.
@@newp0rt TBF I do follow shurap actually, and a I get a lot of guitar building videos (i play guitar), and Primitive Technology is one of my absolute favourite channels on here. I guess it's more that the "LIKE AND SUBSCRIBE" crowd are so loud and obnoxious, it feels like there's more of them than there probably are (and they're not all bad, they're just trying to make a living I guess).
@@spwinaustin I found a few large, light pink quartz rocks that would be great projects. part of my yard used to be a creek so they are fairly rounded, but more of an oval shape. I looked up that machine after watching this video but I couldn't quite justify the price just to make spheres out of these big river rocks bc I wouldn't be selling selling them. who knows though. one day I might.
Beautiful! Who knew a couple handfuls of crushed limestone would polish up so nicely? THANKS FOR FOLLOWING YOUR HUNCH! Looks like a FINE "head cheese"...yummy!
Your videos amaze me every time 👍 First time watching the making of a sphere. Quite the bit of work with such beautiful results !! Really enjoyed watching another great video😊
@spwinaustin I wonder if there are efficient algorithms for cutting a n approximation of a sphere of a desired diameter from an arbitrary starting shape with a finite number of cuts.
@spwinaustin I think that your method is decent. First create a cube at least as thick as the diameter of the sphere. 6 cuts yields 8 vertices, 12 edges, and 6 faces. Then chamfer each edge. 12 cuts yields 24 vertices, 24 edges, and 18 faces. Chamfer each of the resulting edges again. 24 cuts yield many more vertices, edges, and 42 faces. approximate a cylindrical prism along each axis. Decently spherical.
Great video. I was just looking into getting a couple sets of the covington grinding cups, nice to see they worked well. I'd like to see more for sure ^^
That “nipple” sticking out was probably a high point which managed to not get touched by the grinding cups, and eventually got so high and steep that it wouldn’t go underneath the cup to be ground down, and so just bounced around. Great video!
Thank you! If you check my playlists you’ll find at least one more under the “Lapidary Adventures” section. I will do more in the future. They take lots of time to make 😢.
concretion (like concrete but occuring via nature), not a stone, looks awesome im glad ya did it, this runs the risk of flying apart, im not sure what kinda damage such an event might cause unless it happens in your saw
Thanks so much for watching my video, I appreciate it! The gadget is called a slow speed sphere making machine. HP Lapidary also makes a much more powerful high speed version of it.
Just a thought, I wonder if once you got down to the finest grit if you then slowly reduced the bungee tension in steps while continuing to run the machine if you’d get it even shinier? Or maybe even adding in something like baby oil at the end of the process to reduce the grinding/cutting action even further to thereby getting it even shinier than in previous steps?
That’s an interesting thought, I honestly don’t know if it would make a difference. In order to polish you still have to scratch out ever finer lines in the rock so you definitely still need pressure for that.
Have you ever tried using core drills? Seems like you could save a lot of time just drilling out a core, then drilling through the core perpendicular to the first cut. Or maybe just drill out a core then cut it lengthwise and proceed to the sphering step.
I can’t remember the website but if search for Dirtcleaner on RU-vid and check his detailed sphere making video you will get the answer. He says where to buy it and that’s what I did.
Hey, thanks for watching! I can’t remember the website off the top of my head but I learned about it from a sphere making video from “dirtcleanervideos”. Search for his video and you’ll find the answer therein.
Go back to the 1200 to bring that shine out. I can get a mirror polish on wood and metal with 1200, but you don't always get it if you rush that part and keep going upwards in grit. Those invisible sized scratches just get embedded and you lose all the hard edges which makes it harder to bring to a mirror finish no matter how long you go with the 2000. Honestly take it back down to 1200 and run it for longer before heading up to 2k, that should bring out that mirror finish shine, those rocks were soaking up the light beautifully, it could look truly magical.
@@GoldenBoy-et6of quoting Wikipedia Tektites (from Ancient Greek τηκτός (tēktós) 'molten') are gravel-sized bodies composed of black, green, brown or grey natural glass formed from terrestrial debris ejected during meteorite impacts. The term was coined by Austrian geologist Franz Eduard Suess (1867-1941), son of Eduard Suess.[note 1][1] They generally range in size from millimetres to centimetres. Millimetre-scale tektites are known as microtektites.[2][3][4]
Hi, thanks for watching! My build was accomplished by ordering a machine from Highland Park Lapidary!😆 It would be fun to build a sphere making machine from scratch and I promise if I ever do I’ll definitely make a video about it 😁.
The jump from 1200 grit to 4000 grit is rather extreme. Do you have a 2000-grit to bridge that gap? With lenses, the abrasive size is approximately halved at each step.
He Scott! West Texas gal here, found your channel looking for West Texas rockhounding. Brand new to the hobby! I found a little Rock with lots of other rocks in it.(my favorite find so far) Tried using the rock identifying app and it just called it a conglomerate. Google lens called it a pudding stone. How would you suggest I identify stones as a newbie! Have learned SOOOO much from your videos!
Hello West Texas girl! I’m heading back out your way in less than a week for some more rock hounding 🤞. I’m no rock expert but I’ve learned a great deal about how to identify them through RU-vid videos. Look up Shawn Wilsey and find his rock identification series. It was very helpful. Good luck and congrats for living in such a great rock area!
Thanks for the info!!! Good luck! I think you go a little more West than where we are. We are more in the Permian Basin. Hopefully I can venture out more West haha! This is a very addictive hobby! Thanks for the reply and happy Hounding!
Sorry if this is a dumb question (your video just randomly popped up in my feed and I know nothing about rocks) but are these stone balls used for something or are they just for art/decoration???
A chunk of concrete of interesting color. In mu house i had to lay a pipe over a foundation and for some reason the concrete under the earth was red. I have no idea why.
Hi, thanks for watching! The sphere machine comes from Highland Park Lapidary. The sphere itself is not currently for sale but you can usually buy them from and rock shop.
Formations can be found like that in nature. They’re called conglomerates when the stones within the rock matrix are smooth and called breccias when the rocks are angular. If this is natural, it’s likely that it’s some sort of breccia as the pieces within are somewhat angular. I have seen breccias form like this in nature down in the Florida keys. Pieces of rock got trapped and solidified within an old sinkhole.
Good thing you didn’t waste our time with the cutting and polishing process, otherwise I would have just had to go back to my favorite channel where the lady just shows progress pictures and then reveals the end product after her slideshow.
It’s like only chose to stop recording on the parts we want to see… “Ok now I’m gonna set up the cut. Ok now it’s ready to cut and I’m gonna cut it.. ok i cut it. SHOW THE CUT. It shouldn’t take you like 18 minutes to just say “look what I did.”
You mean that wet saw with a lid and water/coolant mixture? Or the wet sanders with a water drip? Serously wth are you talking about also unless its pure granite i doubt its super high silica content. seems like a mixture of rock types which i think he spoke about.
