Making the "Impossible Joint" 四方鎌継

- Making Shihou Kama Tsugi (four-way goose neck joint). When you first look at it, it can be confusing as this joinery is on all four sides, without a way to be taken apart. But this joinery actually slides diagonally, making this "illusion" possible.
The wood is Walnut and Birch.

after watching this, i was inspired and fixed a broken chair leg with duct tape.
Too complicated! Instead I watched a video of a guy repairing a chair with duct tape --- was it you?
I watched an instructional video on CZcams on fixing a chair with duct tape, then I made an instructional video about fixing a chair with duct tape, and now others can make instructional videos on how to fix a chair with duct tape..
@@irieanimalcare2736 Excellent news! I've got beer and crisps, I'll watch them all while sitting on the ground. I'm hoping to acquire a broken chair at some point in the lockdown.
Lol
Well, doing something is better than doing nothing.
I had accidentally turn on auto captioning before this video. Whenever chiseling would occur, a caption would say “Applause”.
Who am I to argue with that.
Underrated comment
It works, 😱😵😵👍
I am in the Nobel Committee, and I think I know who wins this year's Nobel in Literature
👏👏👏👏👏👏👏
Hahaha I am surprised when I saw "Applause " caption.. wtf
My dad is a carpenter and he's always been impressed by Japanese woodworking. I get it now.
This is very interesting to me, not to mention very impressive. No intro, no dialogue, just a mind blowing level of precision and commitment to the craft.
I swear i spent 70% of the video admiring how sharp his chisels are.
Japanese steel is top notch shit
Thank god! I'm not the only one 🙂
Same here
My wife used one of mine as a screwdriver when she could find a flathead
@@apcook34 haha,thats just something to use next time she says she puts up with so much,just be like " says the women who ruins a chisel i have spent and hr sharpening over a screw haha
Making an impossible joint is now legal in 16 states.
It's 4:20 somewhere.
Was already legal for ages where i live 😊
😄😁☘
what
Lol!
Not the kind of joint I was expecting, but still a solid 10/10 execution.
Same
This was exactly what I thought it would be. Just like in the thumbnail. "Impossible joint" is a magic trick / an illusion. Drugs are for stupid people, nobody should make videos of them. :)
@@siipi6331 haha drugs bad
@@leviathan3630 Yes, they are. ;)
Same, but I made one out of rizla and burned it anyway😂✊🤪

When I saw impossible joint making, this isn’t exactly what I had in mind
I was expecting other kind of joint
Thats why I clicked lol
That's the bait
Same here mate
free the joint. legalize it!

Amazing. The use of 'basic' hand tools is stunning - a clear demonstration of craftsmanship. Inspiring !
I was expecting some steam and clamps, not laser chisel precision. Very impressive!
Steamed clamps
@@fedyx1544 An unforgettable furnishing
Same, though i believe that option would've needed quite some laser chisel precision too.
@@fedyx1544 steamed clamps??
@@Ozone946 Yes. It's a regional dialect.
This video isn't click bait, but the joint itself is.
I too was disappointed that it is not impossible
It's smart and plays on pretty clear assumptions. When I saw the diagonal profile I actually laughed out loud and thought it was brilliant. This is one of those things where if I bought one I would say "I not sure how they did it either but I'm sure it isn't a veneer"
I think so too because it’s an illusion, and a lot of extra work for something that probably isn’t as strong as a simpler joint and weaker than what it appears to be.
@@Anvilcjl well no,because this joint have actualy been used time and time again in Japan
Yall really suprised that the video "making the impossible joint" is not about making an acually impossible joint. Like duh, he cant make something that is impossible to make. The joint is called "impossible to make" coz of how it looks
Its so relaxing to watch this master craftsman working. No unnecessary music or talking, just the tapping on the chisel. Thank you for posting this.
Happy to hear that! Cheers! 🙌
I cant believe how many fantastic videos are ruined by obnoxious music.
@@silverishme8675 haha yea
Sure, your preference! Cheers
@@silverishme8675 Sure, your preference! Cheers
Traditional Japanese woodworking is positively beautiful, as well as ingenious. Those chisels are stupid sharp.
I'm impressed that this was done by hand and not by modern machinery. I've seen this joint before but never cut by hand. Beautiful work.
I watched the whole video just to find out how it fits
I watched the end of the video just to finds out how it fit sooner
I skipped to the end...
Noob. I skipped to the last minute
I dont even play the video. I just let my wife tell me how it fits after she done watch the video.
Totaalmeente.. increible ingenio
The noise of the sped-up chiselling is sooo satisfying
Its perry the platapus!
Its like woodpecker.
Watch at 2x speed. It's even better
Trrrrrr trrrrr tar tarrrr
It's like a musical machine gun
What an incredible joint to make! The super sharp chisels and the accuracy of the cuts with the saws, inspirational!
Japanese woodworking craftsmanship is second to none...💯☝🤫
I'm honestly impressed by the craftsmanship. I wasn't expecting the hand tools!
I’m not sure this would be really doable with power tools. The wood work is too delicate for that
@@DK-lz7kg I agree. Sometimes, you need the lighter touch of a human handsaw rather than a circular saw. Much more precise, even if it takes more time.
@@DK-lz7kg maybe a CNC machine but idk
His skills are at peak perfection
@@yyhrva5605 Yea I've seen other youtubers do it with a CNC machine, the fact that this guy did it all by hand is amazing
Wow ! I'm a welder of 35yrs I have since retired my eyes have waned but , they're still good enough to recognize the work of a Master ! What a gifted set of hands I would be proud to work / learn from your skill set . It is my hope that you have and are teaching a room full of apprentice's your craftsmanship you are an Artisan !!
Hope ur eyes get better
Its always good to see people well versed in the field of craftsmanship praising one another

@@imho2278 Thank you for your response ! I don't have cataracts. I'm just an old fart who is losing his visual acuity . Wearing glasses is about as good as it's gonna get for me . 😎
Check out Grampa Amu. He'll blow your mind.
...fellow welder here, btw.
Cool stuff. I love the showing of the whole outside before any marking/shaping. It's fun to pause after seeing the 4 faces, and take a moment to figure out the possible inside shapes!
This is amazing. Elegant and precise. Woodcrsfting in this manner is so rare these days.
Thank you💛
Elegant and precise are often used to describe musicians, authors, athletes. I love that it can also be used for this. Artistic design that's functional.
I'm more impressed with how sharp your chisels are. Jesus.
Yeap, especially when chiseling against the grain
I was thinking it's the wood being soft or some shi lol
Same there - jeez, one slip and down a finger or two!
I took a woodworking class and the first two days were spend on how to sharpen cutting tools. This was on timber frame houses. Wish I could remember it now.😄 neat video.
It is necessary.
3:35
Video: person making the most complex joint
CZcams caption : applause
even CZcams impressed by his craftsmanship
Lmao
I had the same thing 😂
Haha
I don't know what's more impressive. The layout of the work or the incredible chisel work . Truly amazing art.
I am thoroughly impressed! It just shows me how much I have left to learn. I love this type of content, as opposed to the videos that show simple hacks, because this type of video shows you that there is still virtue in dedication and doing hard things. Very inspiring.
Well said
His control is amazing. Notice how he takes small cuts as he chisels. Also notice the backside of his chisel is like a mirror.
You noticed two great points!
Cheers!
That's really how chisels are meant to be used. Same reason chefs don't bludgeon wildly with a knife. It's a fine skill but an essential part of woodworking otherwise you're not going to be able to make anything presentable.
It is said you can tell a lot about some one based on the condition of their tools. Amazing work and amazing skill.
Seeing thumbnail : what? How?
See the diagonal join : Ah, that make sense.
Thanks for your insight
From impossible joint to sorta possible joint
This is peak CZcams comment brainpower
@@johncarlofernandez2698 its 100% possible tho
reminds me of the dove box
I am going to a timber school soon. And I have tried to make wood joints before and failed horribly, but I know how much patience and perfection you need for these thing. So great job 👏
Amazing Japanese wood craftsmanship!
when they said people back then can make homes out of wood without a single nail, this video proved how that is possible
There's a bridge in Cambridge, England, that was built without nails.
Yeah I'm glad I got to witness fine Craftsman but damn
They built entire castles in Japan
And yet at the same time because this one join is this labour intensive, why it is also functionally impossible in today's world
@@greebj you can automate the procedure, though
The fact that he did it all with his hand tools and did not use machines makes it so much better.
Judging from the sound he used a hydraulic hammer.
Since this is youtube, where users are slower than elsewhere: I am joking. And if you were just enraged, then this means you, yes.
Tbf that's how all carpenters make joints if they are worth their salt
@@bur2000 ???¿???
@@bur2000 Looked more like a hydraulic arm than a hammer to me. That sawing was of Steve Austin standard.
For anyone under 40, not the wrestler.
it's the artistry of the design of the structural integrity that makes it 'better' - NOT the lack of using machines.
I have no idea how the algorithm put this in my feed, but it was absolutely captivating.
It is in fact an illusion, but one of absolute brilliance. This is what woodworking is all about. I couldn't hope to get something like this right if I tried it. Hat's off to you!
This guy makes it look easy, but that precision with handtools? That's serious dedication to craft and project, with a heap of talent to boot.
If you keep talking like this you'll never achieve anything in your life
@@cube4547 Ahh yes appreciating other peoples hard work means you will never achieve something.
It looks so difficult because of the speed-up. Wood-carving is so slow that as long as you're using the proper techniques and not too much brute force, accuracy isn't a problem. It's mostly about knowledge and keeping your tools in good condition.
I think wording it as hard work, practice and skill would've been better than talent
@@dovydasgrigas441 there's no such thing as talent. If you keep thinking you need some magic, help from god or genetic luck to be relatively successful, skilled or knowledgeable then you'll never be any of those things.
Boss- "This looks great, we're gonna need a thousand of these by tomorrow."
Because you're so good with it, you're from now on responsible for it
Boss: "Congratulations! You are a victim of your own success."
This... is why I don't get coffee breaks anymore...
@@robdom91 right!
And what i do after lunch ?
Absolutely fascinating. World-class pin-point chiseling to create a wonderful joint. Which is not only beautiful but also seems to be strong as well. Lovely stuff keep it up!
I love how the title doesn't even mention that it's done entirely with hand tools. Masterful work.
@@marxgalacticambition7023 nope, it entirely matters how it was made.
I love watching things that make me realize just how much I suck at everything.
That's what she said
I hate watching things like that
Maybe stop watching and learn something instead?
Naaaaah, too hard.
@@HandledToaster2 people learn by watching though.......No?
@@chaosismyway690 have you learned woodcrafting from this video?
Bravo. The precision of each cut is mind bending, and not a piece of sand paper in sight! 👏

Only one possible conclusion: I know nothing about woodworking
you should at least know that it requires wood.. and working with wood
@@jub8891 NO SHlT????
@@jub8891 GODDAMN!
@@jub8891 My eyes have been opened
@@jub8891 Sherlock Holmes, that you?
Man, this kind of chisel work always blows my mind and impresses the hell out of me because I know there's no way I could ever achieve that kind of perfection, shaving off exactly the right amount, getting all the flats just right. If any one of then isn't just right then the piece either won't assemble, or it might have gaps. That level of precision is just exceptional to me.
You could if you have the right chisels and patience
This isn't talent. It's a skill through repeated actions.
@@tmmnago2722 This guy gets it. There is nothing to prevent the average person from achieving this level of craftsmanship, save for years and years of practice.
@@totsuka2213 well I think the dedication that must've gone into achieving this level of skill is very impressive
Dude you absolutely could make this, all it takes is patience
That’s fricken amazing patience and craftsmanship .
Amazing! Such a precise job without any machinery!
Imagine there being a disclaimer...
"*This footage is not sped up.*"
me: enables 2x speed
That would be funny because technicly the video asked
Howb
Why on earth have 300 people liked this moronic comment. What an asinine thing to say. *Sees slowed down content* “Imagine if there was a disclaimer that said this isnt slowed down LOOOOOL hhahhaha so funny!!!”

1000 years in future, people will find this joint, and think it was built by aliens.
What if we're aliens pretending to be humans

"People in 2020 couldn't have possibly been this smart, they must have had help!"

Right, because it would be unfathomable to future humans that past humans had any skills? Do people think archaeology is the study of alien artifacts?
So satisfying watching a master craftsman at work!
Japanese joinery is always perfection, amazing.
No machines, no chemistry magicks, not even sand paper.
Only chisels, saw, wooden clamps, some hammering. And godlike dedication.
those chisels were sharpened somehow
@@mro4922 You can hand sharpen to a mirror finish like that... I've done it multiple times over the last 3 days.
@@mro4922 probably on a stone.
That lumber is definitely sandblasted before he buys it tough
And to think ancient chinese slaves had to do thousands of joints like these for buildings
That flow of sped-up background noises (church bells, cars, voices et all) is a treat on its own.
Beyond amazing job, and that dark wood sure is extra pretty. This takes great skill and patience! ❤️
Takes skill, patience and years of practice to achieve this. How the 2 pieces slotted into each other is like magic.
As a Danish carpenter and woodworker, I find this very fascinating. I haven’t seen a joint like that before. Beautiful!
go china, u will see more than this,this construction be called '榫卯' in chinese. 事实上,日本的木工技术是从中国流传进入的
@@eugenesilence4009 lol
@@eugenesilence4009 and yet China can’t build roads that don’t fall apart and collapse daily
@@eugenesilence4009 Your social credits have been increased. Congratulations!
The two modern China don’t use this technique anymore. Cost to much time and money.
I love how impossible it looks at first glance, then finding out the solution is very simple - or as simple as it could be if you're a master carpenter!
I really like when a video just shows you exactly what's going to be in it, no clickbait. I could definitely not smoke this joint.
The world needs more of this. Love it!
I love how the wood is hard yet so soft.
Edit: Oh no, what did I just say
lmfao
I feel you man

Very thoughtful idea !!!
Thanks for the video !!!
What a gift you have BEAUTIFUL WORK
If there's one thing I've learned about "impossible joints," it's that whatever it looks like is a lie.
Its called an optical illusion, magicians use them all the time this was a neat example of one
@@ronaldharris6569 always do amusing that usually the trick of the trick is pushing the boundaries if credulity.
The tricked watcher can't even conceive of the work that went into the staging of a seemingly simple trick.
A often it's about putting in a lot more effort than people would suppose anyone would invest for the result.
Magic I mean, not the woodworking.
Is a very beautiful joints, and that is the meaning with this joint
Og
@@asiastreets4032 and it is as strong as the wood so it's a good thing
Thank you for graciously showing us how you made that joint. I thought you might have done it another way, but seeing this solution has opened up entirely new doors to solutions in the future for me to use. Thank you again, this kind of thing is helping me improve my repertoire in joinery, and I appreciate it greatly
Yeah i though it was only on two sides and figured it was a twist on kind of thing
I was simply fascinated by watching this video. This is truly art of worksmanship! Respect!
Any joint which joins a beam with a square cross section, and produces 4 identical faces is conceptually easy. It takes precission layout and execution, but the idea is simple enough.You could even make curlicue faces, although that would be a REAL challenge.
Me: That’s impossible.
Woodworker: I know what I’m about, son.
Give me all the bacon and eggs you have
DELETE ALL PICTURES OF RON!
I call this a turf 'n' turf.
A combination of evenly grained wood, sharpest tools, a steady hand and focused mind, yes this is great accomplishment. I am amazed
Congratulations and thanks for sharing this seemingly impossible task!
Why do you send comments out into the ether? What purpose does it serve?
@@SargentandGreenLeaf aren’t you doing the same thing right now?

I thought it was witchcraft

I made this using light coloured wood and a dark brown felt tip.
Finally after a couple of years of CZcams recommendations, I watch this video.

The sound of wood carving is so relaxing to listen to, I could fall asleep to this video.
japanese woodworking is really incredible how clean it is
Something about the sped up sounds of carving and chiseling is a bit mesmerizing
Am i the only one who thinks that this is really satisfying? Both the sound and seeing him slowly chisel away at the wood
"slowly"... I wish I could chisel away hardwood at this speed with this precision. (Yes, I'm aware the footage is sped up)
That is amazing. I really admire the precision and dedication. Also sounds are pure pleasure.
芸術としか言いようがないです。感動しました！
Imagine the competency of the craftsman who invented this joint.
The chiseling is pure ASMR
Bro same on 2x speed it is amazing
Yeah, it is kinda. I noticed that.
I felt so relaxed, this shit is entrancing.
It lowkey sounds like Perry the Platypus or keyboard clicking at times
That is a killer joint. thx for sharing!
Congratulations on your mastery of the craft!!!
I would make an unfixable mistake so quickly. There isn't a single step to this process that I could not mangle beyond recognition.
THOSE are some tight seams, bravo!
I usually scroll through videos like this to save time, just wanting to get an idea of how the affects are achieved. But the precision and sharpness of the tools were mesmerizing. Had to watch it all the way through. If any of my tools were that sharp, I'd be a danger to myself and anyone within arm's reach. Truely amazing work. Thank you for the video.
Thank you! That's great to hear! 😊
Same here, first I had to guess at how it pops together, then I wondered how he got those tools so sharp where he could push them through hard wood. I ended up watching everything
sharp tools are safer than stump tools😉
@@Hermelin.G1 Exactly... Less force is required to push the tool through the material. Less chance of a slip.

What kind of timber is this? Man it looks amazing. Your craftmanship is astounding. It is so hard to hand carve with precision, your tools are maintained!I work as a labourer doing houselifting in New Zealand. We usually work on houses that are over 100 years old and the amount of timber we pull out that was first sprouted since the early 1800s is honestly what I love about my job. The aroma when you cut through it is one you'd imagine when you think of ancient forests thick with trees that have endured nature and all its chaos yet untouched by modern day pollution. If you were to try to hammer a common nail into it the nail would bend and youd probably hit your finger. It is the best wood for carving and You've given that tree respect, turned it into something that people look at with wonder. I would usually take the timber home for firewood during the winter, but I'm going to buy me some fine chisels and spend some of those cold nights trying to achieve your level of skill. I can't get over this. Awesome.
The brown one is Japanese cherry and the white one is akamatsu . Both are only available in Japan and if you want to importe them they will cost you a Lot
@@mzi6519 dang, well I won't be affording any wood from Japan, however pristine it is. Guess I'll keep working with Kāuri and Rimu for now, just a couple trees native to New Zealand. Who knows hopefully not too far in the future I'll be able to get my hands on some of that Japanese wood.
Edit: I had to capitalize Japanese my grammar sucks but the small j was annoying me.
