- Stone Turning on a Wood Lathe! I take a granite field stone and turn a natural edge/ live edge cup on my wood lathe using diamond tools and polishing pads.
Please be sure to visit bisonhillstonecrafts.com and see all the products they have to offer!
The stone was found on a family farm in Waterford, PA and is a very dark green granite with white veining. The final cup is 3" in diameter and 6" tall and holds about 10 oz of liquid. Subscribe for more artistic stone working videos!

This is awesome! More stone turning please🤑
In India, there is ancient temple called "Hoysaleswara Temple." In the temple, there are these amazing pillars which look like there made with a lathe machine.
Seeing the amount of work you put into this cup, makes me wonder what type of machine could turn a giant piece of stone and turn it into a pillar with small details carved into it? It baffles the mind.
Thanks! I looked up the temple and it is amazing, the people that built it must have dedicated their lives to it. It's impressive it's still around hundreds of years later. I couldn't find what material it was made with? Do you happen to know?

More informations & lot of videos you can study from there.
@@BLOODYMISTYT my favourit channel, great mysteries...we used to have high tech societies in the past....but mainstream says we come from apes, lol
I recently saw that video. While I agree that some type of lathe must have been used in the creation of the site, I think that particular stone is a millstone. Probably used to grind flour from the dozens of different grains and seeds that would have sustained a vegetarian culture (for - in this case 500 years)...
I've watch that channel. It's more than incredible; it's incomprehendible. The temple looks like no other temple: is totally dark inside, totally out of place in every way. We must thank the Sire Mohan-who is a gift-but the mystery is even greater than it looks.
I cannot escape the sensation that a lot of those places in India were built with the express purpose of wowing us now. They are a message from the deep past to our present. A subtle message left like a coded picture for us to unravel, to alert us to something strange, and something wonderful.
Very relaxing. Thank you for this.
Beautiful!! I was thinking of doing something similar and then stumbled on your video. I wasn't sure it was even possible, in fact I thought I was a little crazy for even thinking about it. But thanks to you I know now it can be done. Not easy, but definitely possible!
Definitely not easy or quick, but it turned out beautiful!
in a hundred thousand years it'll still be there for future generations to display in a museum and ponder how the primitives made such things.
Yeah except when they find it they will immediately known it was created on a lathe, if they smart enough…there are very obvious signs of a lath spun piece
They will also probably find remnants of his carbon cutting blades… leading them to some rather reasonable conclusions
The ancient "egyptians" made lathe-turned granite vases with 1/40th of an inch thickness and whose dimensions all correspond to the the Golden Ratio or Pi.
Oh my god. I was watching another video where this woman was unboxing a bunch of stones, and some of them were mushroom-shaped and looked like they were crafted on a lathe of some discription. So happy to learn that it's an actual thing!
This man has a cavalier disregard for his own fingers :)
Yep fingers are good, even useful, not so good standing up and looking at them on the floor.
They usually do until they lose one
You'd have to try really hard to get those blades to cut your finger. They don't have sharp edges, they're just covered with tiny diamonds.
@@TrailChaser yes it'll grind or otherwise simply work off your fingers.
to be fair, it looks a lot more dangerous than it actually is when it's sped up like this. real time stone cutting is pretty slow going
Good jab thanks for sharing
Excelente!!! Saludos desde Lima.
That's cool!
Thanks!!!
Just watching this video and seeing the amount of work and the difficulty of the required tools involved...I am amazed by the built artifacts from the Ancient Egyptians..Truly Amazing Technologies involved by the Ancient Egyptians.
hahahha, no way with hand tools mate, no matter what they say...the marks speak for themsleves
they would of used something similar to this wouldn't be hard to make a lathe type of machine powered by water look at the old water mills
I love this
amazing video! thank you.
just curious about your water set up. What did you use and attach the water feed to so that it is directional? and do you have to keep it away from yhr motor? i am thinking about this set up but for much smaller pieces. and i was worried adding water near the moror as its usually used for wood which runs dry. Could you help me out?
thanks so much
I too plan on trying this wonderful technique. I think as long as try and keep most of water away from motors like how he has the plastic covering the worrisome parts we should be okay. If you haven't already tried @sarah Eisman I shall be the guinea pig and if I don't respond in a few days then I probably got electrocuted lol then you'll for sure know it wasn't a good idea 🤣 j/k safety is always priority 😁
Really cool thx :)
great piece. I like that you left the crack section instead of cutting it down.
Thank you! I do believe you are first person to say that, most people think I should have smashed it and started over. It's not super functional with the natural edge, but it's cool to see the weathering zone of the rock
@@bisonhillstonecrafts5122 oh most definitely, little touches like that add more character. Keep up the hard work!
Wondered how you were doing this so a lathe and diamond tools truly cool and makes sense just gotta be water-cooled for preserving tool lifespan
Well, that and preventing silicosis
This is like a scaled down representation of how the massive stones found at ancient megalithic sites were processed.
Without electric tools and no videos on how to do it.

Nice work , would this cup float on water ??
Nice
Thanks a lot for sharing! Just a few questions; what the use of the little water pump attached to the machine? Does overheating have serious consequences while working with stone ? Is any lathe wood machine also suitable for stone? And what would it be the average cost for buying a similar one you have? Thanks !
The water pump keeps the stone and diamond tools cool, and it keeps the dust down too. I'm not sure about every machine, there are definitely some cheap ones that wouldn't work for stone. The tools I used were over a thousand dollars combined so it's not super cheap to get into.
Cooling is important to keep everything from expanding and contracting. It's also important to keep the tool cool. Steel aspects of any tool head are hardened through a process called HEAT TREATMENT. When steel is hard it becomes very sensitive to heat. Temperatures in excess of 200C will alter the properties of your steel and above 400C, generally speaking, ruins the heat treated mechanical properties of the steel. Often diamond tips, or carbide is fused to these steel tools in order to work material harder than the steel itself.
I work with stone on a daily basis. I can tell you that unless you are working with soft stones dry cutting is next to impossible. The cutting surface is equal to the amount of abrasive material making contact with the stone, ie how many diamond points are actively scraping the rock. The amount of friction generated is enough to send steel red hot fairly quickly. Working with cultured marble with a quartz substrate I can tell you that it eats through a dewalt XP4 blade in a matter of days worth of cutting. When it is darker out you can see a steady stream of sparks emanating from the contact point as the diamonds heat the metal around them and abraid both the stone as well as the metal they are impregnated in. Without water cooling you would have to have a steady supply of blades to keep changing.
Sert işçilik, güzel sonuç...👏🙂
Ticonderoga pencils are so versatile
Can you make a video on how to set up and use water powered dust control measures for odd/abnormal uses?
You’ve shown the Egypt archeologists how its done 😊👍🇨🇦
With modern tools and machines 😊
Can we use any tool bit on my lathe machine 🤔
I had no clue this could be done on a lathe like this. I have that exact same lathe.
Id use a diamond cup wheel instead of a large cutting blade like he did. Slappping a huge disc like that on a small grinder(non variable speed) is a safety no-no. A very quick way to the ER, darwin award style.
Is that just a steel lathe adapted for stone? What is the smallest stock you are able to turn on it? I’d like to set up something similar for turning marble and granite chess pieces, but I’m worried that it would be too fragile at ~1.25”
It's actually a wood lathe, I haven't played with super thin material but I did break some marble that was around 2 inches thick. Some rocks have cracks naturally running through them so you have to watch out for those.
The cup would make an excellent crucible.
perfect
Could you recommend some diamond burs? Just getting into stone work and can't find any good burs
There are sets on Ebay or Amazon for pretty cheap that work good, just make sure you use water with them. Get a more aggressive grit (40 or 60 grit) to take more stone away faster too
Nice toolbending! Classiest dribble glass ever!
Seriously though, I like the inclusion of the imperfection.
What’s that bit you use at the end to finish the bottom? I need at least one of those, maybe different sizes if they make them. I always have a hard time finding the tools I want for stone projects.
The Wales slate is the best 👌
I have that exact lathe, and I have turned wood, metal and plastic so far...
let me know when we learn to work on granite & basalt with copper tools, then i will built a pyramid with lots of slaves, lol
There were no slaves
They still work stone today in Asia using this method.

@@sharonjuniorchess that video doesn’t even compare also why listen to Russian trolls
@@manbearpig710 How exactly does it not compare? I would like to know what makes you such an expert that you can say that this method does not work and could not have been used then. It is no different to the practices carried out by stone workers in Asia today that have been passed down through the generations. Just because the people on the video are Russian does not make them trolls. You should have learnt that lesson from the now discredited fake narrative promoted by Hillary Clinton to deflect attention away from her illicit financial dealings with Russian oligarchs that were being exposed around the Uranium One scandal. Joe Biden does the same with China. Why do you need to stoop to their level and trying to discredit others. Surely you can put together a few words to do that rather than just casting unsubstantiated insults against people. At least these guys are exploring how the Egyptians (or whoever was before them) did it. Its a form of reverse engineering and it seems very credible to me.

When you're polishing the inside of your vessel, you could try wrapping your hole saw with carpet tape and and then sand paper
Wow! Impressive. Why did you work from the back side of the lather? How much total time to make this?
Thanks! Partially for filming and partially for the relative motion of the tool vs the stone. It was about 40 hours over the course of a couple months.
Bison Hill Stonecrafts hi , does the larger disc really lower your working time ? (Sorry for my english its not my native language)
By the way.. this is a masterpiece !
How long did it take to make your cup?
Bro, that looks really dangerous!
It's not as dangerous as it looks, the diamond blades I use won't cut your skin like wood saw blades.
Cool
Saludos y bendiciones! 🙏🙏🙏
Diamond disks are really dangerous, be careful mate!
@@bisonhillstonecrafts5122 It was the water and electricity especially from the dremel that weirded me out. I'm scared to wet dry sand paper wood with a finishing sander. You have balls my friend...Bison balls.
So that's how the Egyptians did it!
Im seriously wondering how they did.
And the lingam in india
As a geologist, and a wood worker, I am absolutely impressed and green with envy. Out of curiosity, how long did this take?
Thanks! It was a long process learning and testing off camera that took over a year, but I'd say it was 40-60 working hours.
@@bisonhillstonecrafts5122 40 to 60 hrs? Whoever carved that granite in pre Egyptian times must have had some incredible machinery.
@@whyattrmellon5269 indubitably!
@@whyattrmellon5269 there a video of a woman attempting something like this by hand took her 6 months and no where near the quality. The official narrative is beyond ridiculous. The Egyptians were far beyond our capabilities and understanding of life and materials.
@bisonhillstonecrafts5122 your saw always makes me nervous, isn't their more.safer.ways you can cut stone, or just grind it down on an angle grinder, not to mention they make stone bits for the lathe.
Assuming I know nothing about turning stone "Other than that stone is involved, I kinda don't." I do have that same machine though. Where do I find the bits? Thank you and this is a lovely piece of work!
You can buy diamond tools online on Amazon or Ebay. They aren't anything special and are relatively cheap. I'd start with a Dremel and some diamond grinding burrs on some stones you find in your area. Good Luck!
Do you think this is possible with Quarts? I have been wanting to make an urn for my dog from rose quarts and I am trying to figure out how... Maybe a dremel would be best.
The problem with quartz is that it tends to contain many internal fractures. Finding a piece of unfractured rose quartz of sufficient size would be difficult and expensive. It's also harder and more brittle than granite and thus more difficult to work. A chunk of agate would work, if you have a great deal of patience and time. Large chunks of agate are available, depending on where it's from, for instance Brazilian agate is relatively cheap.
@@r.awilliams9815 don't you know all you need is some good Ol Egyptian vibrations?
Really Innovative use of a cheap wood lathe from Harbor Freight and some industrial Diamond discs with an angle grinder.
Especially genius is the creative use of diamond hole saws for the chucking solution and hollowing out.
Subbed for the skill and daring alone, and because I've seen a lot of crazy stuff as a machinist and watchmaker, but never seen this done before.
Have you ever done solid quartz crystal goblets?
Thanks! You actually hit the two things I spent the most time thinking about how to make work!
I have it on my list to take a single quartz crystal and make a shot glass but haven't had the time yet. Thanks for the sub!
What was your reasoning for choosing to leave the huge chip in the rim ...? It’s a major deterrent for me
I would rather it didn't have the edge on it too, it would fit a full beer that way. But if you look at the beginning of the video the original stone has a depression in it that I couldn't avoid. I had already made up my mind on the shape so it was either make the cup 2 inches smaller or live with the "chip". It's kinda cool though because the whole weathered zone of the rock
do you have a recommendation for brands of long lasting stone cutting bits or drills. seems like the ones i get only last a few minutes. thanks, mh
Diamond coated tools should work and last a long time, make sure you are using water to cool them off though
According to mainstream academia all you need is another stone and a bronze chisel, and you can make polished granite vessels perfectly symmetrical and less than 0.03 inches thick. Easy!
Ami me gusta trabajar con piedras como me gustaria aprender mas
Looks like you’re working off the back of the lathe? Reason?
Partially for filming and partially to keep the water from spraying all over me
6:24 could this be done with the saw drill offcenter, with OD of the blade positioned on center? (just in theory)
Yes, the difference is that you'd have to grind away ALL the granite inside the cup then. It may seem like a ton of work to change the tools, but in realtime it is much faster because the grinding time is greatly reduced.
@@bisonhillstonecrafts5122 Ok. Thanks for reply. Was just curious if the diamond will cut that way, because I've no equipment to try it by myself so..
Now make one with walls the thickness of an Uno card and you’ve got yourself a 15,000 year old Egyptian vase 😃
Don’t forget to leave material on the side for handles…. How the Egyptians did this with primitive sticks and rocks is amazing 😅😂😂… The Egyptians were so advanced it’s mind blowing 🤯
да безопасность просто на высоте ,видно все пальцы на руках как можно так работать.
Great stone work, but please put on hand guard when cutting stone bro
I bought a turned stone cup and now it bleeds through when I have liquid in it. can somebody tell me how to fix that. thank you

it would be cool to see that chip in the cup filled with epoxy and stone fragment dust
I tried epoxy in another project and thought it turned out cool, but I wanted to leave the edge natural on this one just cause I was feeling it.

How to finished inner bottom surface
With the blue sandpaper in the video, I just pressed it against the bottom. It's not nearly as polished as the outside but it's good enough.
Can you do it with a copper chisel and a wooden hammer pre-dynastic Egyptians did 3000 bc in granite with a 3 thousandths of an inch tolerance
People have reproduced vessels using tools/ methods available to the Egyptians.

I call BS on the 3 thou tolerance though, I've yet to see someone actually measure any of the Egyptian vessels with a measurement device capable of resolution down to thousandths of an inch.
@@bisonhillstonecrafts5122Why dont you measure yours? A dial is only like 20$..
This kind if technology was around before rhe dynastic Egyptians
Nah, it wasn't. The Egyptians were just more clever than me and you
@@bisonhillstonecrafts5122no n-answer.
Good work, and I like the technique. A shame lathes are so expensive
@BKNY FINEST ha same types of videos brought you here as me. While they must have had some tools we haven't found yet, how do you feel about the claim that we can't create precise granite turnings today? This guy did it with a lathe and some regular old hand tools
@BKNY FINEST yea its crazy for sure. It may not be something extra spectacular either, just lost lathes and other mechanical machines from a pre-dynastic era that they inherited. Not sure why we haven't found any of that stuff though
I do believe lathes are the scariest thing in any given shop. I'd love to work on one, but I can barely butter bread without cutting myself. I'd get scared I'd catch clothes in it then go in naked and catch something worse than a cold.
Is there any safer way to cut that stone?! Your fingers are literary a few inches away from that bloody cutter :D
yes, that was crazy. also rather impressive strength. Lots of rock holding jigs, most use some type of toe clamp type arrangement. My saw is similar, but the rock is held to the table & I push it just like you would with a tile on the table. a lead screw lets me slide it over in a controlled manor, ive made a lot of coasters that way.

So you can drill into granite with a cordless drill year people still say it is impossible to do without magic high technology.
But predynastic Egyptians did it with copper hand tools.
Why the music?
Yeah that broken area turned me off too.
Been in cnc 13 years. Hardest thing I’ve ever turned was titanium. This was great to watch
What’s the point of using stone with a broken edge? I can hear you now, well it creates negative space or it’s more interesting. Tell that to Michelangelo, I’m sure that he’d agree.

No the Egyptians did it with copper chisels and wooden hammers! Or so they say 🙄 lol, my guess is all their lathes and mechanical tools rusted away after the flood and all the craftsman died off, we can all use a cellphone but how many of us can make one?
Craftsmen DO NOT leave their tools behind, when they are done, they pick them up and move on to somewhere else, same goes for today, and also was the case in the ancient world!

why spend all that effort on a piece with a big chunk broken off the edge. just get a new piece of stock and start over
cups got a big chunk out of it
Yeah, I didn't lay it out perfectly. I would have needed to make it way smaller to get rid of the natural edge. You can see at the beginning when I put the chalk on the stone that there is a divot in the one side that edged up being the missing chunk.
@@bisonhillstonecrafts5122 its still pretty cool. Just sucks you put so much time and effort into it and ended up having a big flaw
@@kindredspiritzz66 I truthfully don't mind the look of it, it's the natural edge of the stone so it's kind of cool that it's unfinished. But it only holds about 10 oz now too so I have to take a couple sips of beer before pouring the rest in haha
So how do you think the ancient Egyptians cut granite pottery with hyper precision?
The same way as in the video, with diamond tip implements, lathes and power tools!
Why would you do the whole thing with a HUGE chunk missing from the top??? 😡

Cool video! I would love to know what you think of this video titled "Precision! - Evidence for Ancient High Technology, part 2". It covers various ancient Egyptian artefacts made from granite and other extremely hard stone. most astounding were some difficult vase forms made with extremely thin walls. Seems impossible after watching a modern approach with a lathe and diamond abrasives. Their era having supposedly not even made use of the wheel yet, still using copper tools...
Thanks, Glad you liked it! You lost me at Ancient High Technology though, I don't even need to watch that video to tell you it's absolute BS
You should check it out before you come to that conclusion! I found it to be a very interesting and well made documentary. Some of those artefacts are extremely beautiful and precisely made for 4000+ years ago. Would be keen to know your thoughts if you do give it a watch.
