The pivot point of the slats should be above the slats, so that when you push down on them the naturally rotate to the optimal position. They are kinda "over-center" as is. Love the idea!

That is a most Streampunk looking seat frame. Fantastic work. The extra 4 unused holes could be used to mount a custom sensual Hand Tool Rescue logo. CNC cut out of brass, of course.
I love how when you drilled those first holes the CC said "Applause" and then the bandsaw was "foreign". Absolutely the best start to a video beyond your intro
You should attached a layer of leather over the slats. You wouldn't be able to see your fancy cherry wood, but it would help the slats move as a cohesive whole, as one continuous surface, while still allowing the seat to conform, while simultaneously preventing pinching.
Those wood pieces could be taller and also wider, so that they would always be aligned upright with a help of few rubber bands going through. The holes for these bands should be long lines so that the band could move (not necessarily in the outermost panels). I also think one more layer of "fractality" and even narrower thin slices of wood would be better.
I think the main problem is that the surface of the slats that you sit on is too offset from the axis of rotation of the last stage, and they are too narrow. This makes them want to flop over when force is placed on them, rather than pivot to be normal to the body. Also if they attached 'inside'/between the pivoting metal parts instead of 'on top' of them if would also allow them to be wide without obstructing the metal parts - may need an eccentric shaft to connect the two sides and allow the wood to still be on axis, or just use the wood as the shaft. I agree that in addition to this, some kind of flexible strap between the boards to encourage them to follow a continuous curve and be less independent would also help. Perhaps a couple of elastic straps stapled to the underside of the boards. An elastic strap may also help reset the chair to a neutral position when you get up.

Easily my favorite part of these videos that I think most people miss out on are the closed captions during the machine work. Truly spectacular attention to detail.
Thank you for reminding me! HTR - put a clever reminder on the intro…make your cc work worth it! Oh, and you didn’t have an intro this time! I love your intro!
My 40-year-old bed base from Dunlopillo is very similar to the principle here. In fact, the principle was quite widespread for the high-end segment in the 1980s, before the waterbeds and the mattress construction with foam layers took over the bed market.
One of the first things I learned on mine was that the first layer of fractalness needed to have the pivot point above the butt-contact area. Having the butt-contact area above the pivot, as you did with the wooden slats, lends to a pinchy situation. Mine is actually quite comfortable, though not as beautiful as yours. Good job Eric!
@@michaelsorensen7567 What comes to my mind is to make the uppermost fractal pieces a sliver of a circle instead of a semicircle, so that the center point of the arc is above the slat. Pictorially, going from a 'D' shape to a ')' shape if that makes sense
Bravo 👏 Had a thought on stabilizing the planks of the seat. A guide cable. Drilled through each plank, counter sunk at each end. This will orient the plank into a curves.
You, sir, are my kind of nerd. I started watching you with the restorations, and I love the arcane patent builds. Thank you for being you, and please keep it up.
Nice job! Sitting on it could be more comfortable if the wooden slats were on an L bracket so that their center of mass would be below the axis of rotation.
This bothered me as well. It's not about the center of mass though, but the height of the plane where the forces are distributed (should on the bottom of a slope to self-center, not on top of it)
I am wondering if you can make the wooden planks to have their top surface to be almost where the center of rotation is for the smallest fractal pieces. Right now when you sit on the chair, the planks experience a big rotating torque, because the surface is far away from the center of rotation. So instead of conforming to the shape of one's bottom, they seem to want to rotate away. You might achieve this by either drilling a long hole in the planks to put the steel beam inside, or machine a groove from the bottom (which would likely be easier than drilling a long hole).
Cool stuff! You could try replaing the slats with rollers, and cover those with a "thin" sheet of rubber (which should extend slightly over the sides, helping prevent pinching), then cover that with an upholstered cushion.
@@kirbyis4evera cushion isn't rigid enough to make a difference. While it may lesson the effects, because it creates a single surface; it wouldn't be near enough to stop the device from working. It would be like putting a cushion over a hole. The cushion isn't going to hold up to human weight being ontop of it. Rather a human would fall passed the cushions position, into the hole.
I agree that is it very cool and the job is great. There is another problem: this item is usless, apparantly incovenient to sit. This is a big and primitive misconseption that things should take the shape of a human body. Why? To minimize pressure on body? Again, why? Some elementary thinking should reveal that it is not helpful.
I just got back from working at a shop in Nepal which had the worst drill press I've ever used. I never thought I'd be so happy to see a well working drill.
I think having the wooden parts be 'hanging' below their respective sections' center of rotation instead of 'balancing' above them would help a lot with comfort. Also, I feel you; I'm currently waiting for the operation of my own hernia, which I got doing something possibly even stupider than creating this chair: doing another persons' job, because I thought it would be a good idea to get it done while there's time.
Either hanging slightly below, or be at the center of rotation (maybe just use wood planks instead of metal bars for the final layer?) with wider planks that "fill" most of the gap between adjacent sections.
I admire your skill and ingenuity. Hopefully you are also inspiring the young craftsman of the future. Imagine what wonders they will create!!! Thanks for posting this video!
Nice work. I think the main improvement would be to make it so the surface of the slats (the surface you sit on) pivots on the center axis of the last stage. If they attached 'inside' of the pivoting metal parts instead of 'on top' of them if would also allow them to be a lot wider. Currently the slats being offset from the axis and very narrow makes them want to flop over.
What you are describing is a bed of hydraulic cylinders all connected to the same reservoir. The cylinders can all move freely, but the average has to stay the same.
@@Rudmin I think what he is describing is fixing the wood beams on the smallest fractal:s pivot so it isn't top heavy, and have it be wider since it doesn't have the same space constraint anymore. Idk though since I haven't watched the video.
I think the final stage should be padded cylindrical bars. That would take it away a bit from the original intention, but I think it's a necessary concession because of the imperfection of any such mechanism.
Fantastic execution. And now we all know that while a fractal clamp is great for holding material, using one to clamp your seat may not be the best idea. Well done sir.
I love the problem solving and humour. The only problem with the chair is that the slats are fractal in 2 dimensions only. To get real comfort (and extra pinching opportunities, obviously) each slat would need to be made from 4 (or more) fractal pieces. This would make the seat truly 3-dimensional (like peoples butts). The weight would only need to double or quadruple as would the complexity. :)
tridimensional tiny structures that are affordable and reliable enough for a chair ? humm, i dunno, there is this tecnology called FOAM, it can be salvaged from sofas using a hunter knife or you can buy it like a regular person
@@josephwheeler1 I find it easier to approach this piecemeal. First figure out how to engineer the 3 dimensions before you break out the expense of a 4 dimensional chair (be that in $, complexity, weight, etc.)
Can’t wait for the full body version! And I’d also like to see it with round wood slats, dowels if like, with metal rings on the ends to reduce wear. Those could rotate freely and be placed closer to each other 😊
Flatter slats would roll less and tend to keep the flatter more comfortable side against you instead of rolling so you're sitting on an edge instead of a flat surface. If you're concerned about structural integrity, try making metal slats. The finished chair has a steampunk vibe to it.....kinda cool!
@@ShadeTheif Perhaps, but not EVERYONE weighs 150 pounds. That extra beefy construction may come in HANDY if someone over 250 pounds decides to sit in it.
@@juliebaker6969 if you used thin metal slats then they would bend under the weight of a heavy person down to those beefy rods, potentially further increasing comfort.
@@joedingo7022 Thin compared to those 2 inch square wooden slats he used, not thin like made out of tin foil. About ½ inch thick should do it. Steel, or better yet spring steel slats 2 inches wide, ½ inch thick and 19 inches long would hold a grizzly bear without bending.
Amazing concept! I think the wood shouldn’t be on top of the semi circle. I imagine the ballast of a boat, it sits high and wants to tip over. Drill the length of the wood and slide the rod through it and then attach the semi circle portion. Or make another subdivision and instead of wood, brass rod. It rolls and no pinchy-pinch.
I was thinking the same. also, the chair differs from the fractal vice in that the large semi circles don't need to be nested within each other, each can , using a ball race for smoothness be arranged with the largest semi circles to the smallest from outside to inside of the chair. so long as the wooden laths are longer than the width of the posterior, then the height of the metal semi circles will not be an issue.Also, i would like to see a version of this made for a bed, because i have a bad back. we can build it, we have the technology.
That's so cool. I can't tell you how much I wish I had a fractal vice. Because of your channel I bought an inclinometer, a bedrock hand plane, a combination plane and several other assorted old school tools.
Fascinating engineering. The most comfortable conforming wooden chair I've sat in used flat wooden blocks interlocked with rope, which I think required tightening on occasion, supported by a solid wood frame. The result was a perfect balance of stability and adaptability.
beautiful craftsmanship the integration of the brass hardware is *chefs kiss* i think Ray and Charles Eames would have sold millions of these if cnc milling existed in the 40's and 50's.
I can't stress enough how much I dig your videos. You're a hard worker who does some damn cool stuff and you have exactly the right sense of humor, it fits my own like a fractal vice. I'd buy you a round in a heartbeat, thank you for always bringing us such solid content brother, keep up the great work \m/
A couple months ago a non builder friend of mine and I had a conversation about a wood couch, and something not too far from this is what I came up with. Wood slats with some ability to articulate and deform from metal joints and springs. I figured it would be a ten thousand dollar couch, but that someone could pull it off and make it functional, comfortable, and nail the aesthetic. Lo and behold, you're evolving a test mule in your garage:)
One thing I LOVE about your channel is the lack of music (excluding your awesome intro.) It makes your videos in my opinion the best restoration videos on RUclips!
I only know this concept from scifi books, great work, really impressive. I would say with slightly different materials and additional analysis regarding body measurements, you have built the next generation of high-end seating furniture
@@randomd286 Nice thing about the chair is that it doesn't have foam that flattens/wears over time. I imagine there's a lot of other maintenance though.
This is an interesting concept that could probably be improved upon. My personal first thoughts is to go an additional step deeper for finer variation and to pad the slats, possibly a slightly elastic cover similar to the sheet fabric that lawn chairs use. I'd also be interested in seeing this on the back of a chair, given variation in spines, could a form-fitting generalized spinal curve work using the same basic concept. Also, I'd be curious to see how the various slats follow the body throughout various postures, say going from feet flat on the floor, to a partial lift, to a full lift, and with a flexible back pivot how the slats would follow the body through various reclining angles; between a fully flexible system of the 'fractal' pivots, I want to see how a full chair made of them follows the body's shape from a proper sitting upright to a full lie down, with every leg and hip angle between. Furthermore, it'd also be interesting to see what this could do for neck and head rests, and the various movement the upper spine allows. Though at the same time, I think the variability could also lead to disfigurement over time, so much movement that it becomes a hindrance to having better posture; but I also wonder if something like this could be biased with springs to promote a more natural shape for the body, of course tunable due to variation from person to person. It'd be interesting, as there's more variation to people than just height (and thus things like scale of body curvature, specifically the spine, why adjustable lumbar is a thing) but also how people carry muscle and fat, not to mention individual proportions; personally I've had issues finding things that fit me correctly, as I'm tall, lanky, and scrawny, so I'd need a custom chair first of all, but imagine if a self-adjusting chair existed that not only comfortably fit me but also comfortably fit someone who is short, squat, and well filled out. At the same time, I think a concept like this may work better a 3D surface, as the body isn't flat. Though this wouldn't make this mechanism all that more complicated, just have depth compression along the slat. Similar to other things not fitting me correctly due to my body shape, I also feel like the stick-out of my spine is a bit exaggerated, any time I sit into a hard-surface chair, especially slatted (vertically or horizontally) ones, I'm always very aware of when my spine touches and how much discomfort it causes, I feel like my spinous processes are just abnormally large; which is why a 3D surface would be a better fit, as it relieves pressure from a specific area and rather distributes it along the surface. Though, cushions and padding basically do this anyways, problem is that cushions get hot; especially for someone with heat sensitivity and atypically high body temperature. Gel pads could be a solution, but they're an imperfect one, especially as a lot of them show atypical properties once they're warm, and really aren't as 'breathable' as marketing might tell you; sure, they may be a bit more open, but only along one axis, of which also doesn't see airflow, and even if it did you'd have to push air in to push air out as they're a cube with all but one side blocked, air cannot freely flow. I think the ultimate solution would be to use a compliant form as a 3D sprung surface, yet producing such would require a stupid amount of R&D work, even if the structure and materials are heavily borrowed from other sources. I just want a chair that forms to my body structure, promotes healthy postures throughout the ranges of sitting up and lying down, and has comfort and breathability. This strange little bench could be a stepping stone towards that, but inherently is complex and expensive to tinker with; though I might take a shot at it with other materials and a modified approach, at least before moving onto other ideas.
I would argue that the back could be connected to the seat and basically be a copy, or rather the chair would be just flat when not in use, then you sit on one half and the backrest comes to you, this would allow you to sit in any position between sitting and laying down.
hey man i've been independently working on designing a chair (and more broadly a healthier more modern workstation) with a lot of these considerations. if i ever actually make it, ill make everything publicly available and update this comment. but yeah, thousands of years of chair design and even herman millers best shit is still worse from a first principles standpoint than this fractal chair imo.
This belongs in a gosh darn museum, dagnabbit! This is art. This is not furniture, this is art. And furniture. Furniture museum? Do they have those? Make one just to put this thing in it!
I wonder what would happen if you tacked a piece of stiff leather or rubber to the top of the slats. It wouldn't move nearly as much, but it wouldn't kinda collapse in the middle either.
I was thinking a special-made cushion where the bottom of it has a ton of extra fabric between each button-point (to the max extent of each joint), and the cushion snapped down with the big metal button snaps, two to a slat. Then you could have a cushion that wouldn't get pinched, and could kinda "accordian" to the shape the chair took- I'd recommend to go heavy on the infill though, since the infill is going to get stretched and crushed a bunch, and you want it staying firm. Think on the cushion height, so that you could still feel the mechanism operating well.
I think what will make it more comfortable is to make the slats concave. They seem to rock back a forth a lot because the pivot point is so low. If you make the slats concave you can reduce that distance and make it so the slats auto level as opposed to roll to the max one way or the other. I think that will increase the comfort and also reduce the pinch potential.
I have no idea why this video was recommended to me. I don’t make things, nor do I watch videos about things being made (usually). But it was hilarious and interesting and I watched the whole thing.
Man, I love your work and you being here. I suggest making the wood pieces concave, so they equilibrate in a point and do not diverge to a point where your valued belongings get endangered. Other way, you could have put two wood pieces separated in every last moving piece
Like most of your content, this thing is *kind of* ridiculous. And also completely, absolutely, utterly amazing. I love your content. Never stop. Ever. I mean it.😂❤👍
Eric you sir never cease to amaze and deliver entertainment and quality craftsmanship that chair is absolutely gorgeous. The way to prevent warping on laser cut parts use cold rolled steel no internal stresses as with hot rolled material
This channel is by far the Funniest and well put together self talk/ sarcasm/ shop talk I’ve seen on RUclips. I thoroughly enjoy the humor and the content.
I really do love the steampunk aesthetic! You can never have too many brass fasteners! I think one thing I would change is going from bare wood slats to crushed velvet over the wood slats and maybe some rubber between the middle slat to lessen pinching. I can see why this chair was never made, it wouldn't be very cost effective to mass produce. The best it could be is some sort of luxury custom item. But I think nowadays, you could probably make something like this with modern materials. Cool and fun video, glad I found your channel definitely subscribed.
Yeah, right, "that chair is a piece of art". Sure, why not... taking into account the latest "art", it's just like that painting that was painted using real human sh*t. This chair is the art companion of that painting. Now, more realistic: that chair is a direct ticket to a spinal and back issues in less than a year of using it. It should have never been allowed to exist...
The aesthetic of this piece is really interesting. If you’re in the mood to make another chair how about a steel rocking chair with clawed feet and a mechanical rocking action? Bonus points if the rocking action connects to gears like an automaton, or generates electricity
This looks really great. You may be able to make it more comfortable if you could limit the pivots with a tension like device like springs or Bungie cords that connect the first or second level half circles
I think the brevity of this episode belies the extraordinary amount of effort that must have gone into this project. I can imagine this ending up in a museum. Is it art or engineering? 😊
My only issue with this (besides the pinching and things which can be reduced by connecting the wood straps together with leather) is that it is only fractal in 1 dimension where as the butt would need it to be fractal in 2 dimensions. I don't know if that is even possible. But it is why soft things and not wood are now mostly used for chairs.
you should upholster the wooden slats such that they cover the gaps, than the pinch factor is reduced. It would also look nice and feel more comfortable.
Fantastic! I do think the top of the slats should align with the pivot of the final element though so they just tilt without the forward/backward motion.
LOVE IT!! I very much look forward to EVERY new vid. The generous sprinkling of irreverence and the uniqueness of content make this channel one of the greats. Sorry to hear about the hernia but glad you're on the mend! 😃 Cheers from Sussex NB.👋
You are a true actor sir, I really do enjoy listening and watching to how you present things, well done on the work it's as great and amazing as your actorship! Love it!
This was really neat. In addition to the adjustments suggested by others, perhaps some light preloading of the pieces would be beneficial, so it springs back into a flat position when you get up? Could make it more repeatable and less pinchy :)
Really great to see such a wonderful whimsical chair! I’m glad your recovery is going smoothly. I wonder if some kind of (merely one pivot point) foot rest bolted to the frame would make it even more comfortable. Is there any possibility to spring load the 4 secondary fractals (like a spring in tension pulling them down, so they want to be centered) to add some resistance to your butt sinking down in the center? PS: might of missed it, but is that your poor lathe? Did it get refurbished? Did it do all the work? It seemed to handle so much work pretty well.
Nice. I can see one thing that might make it more comfortable. Instead of the smallest pieces being half-moons with stats attached to them. make them completely round. Then attach round dowels or rods to them and add padded tubes. Should help quite a bit with comfort.
Dumb is not a word that I would ever equate to you 🙂. I am always blown away by your skills, drive and knowledge that you express in your projects/ videos. I always look forward to every new video.
If you could mount the slats flush with the metal pieces holding them, the design should work considerably better. The surface should be flush (I think the math term is coplanar) with the axis about which it rotates (or maybe lower? I'm not sure), so that putting a flat object on top returns the slat to a flat position. Also, I wonder if you could do something similar with tiered leaf springs, the way some (older) wiper blade designs conform to the windshield. No idea how feasible that would be.
I think that the wooden planks should be lower so that the axis of rotation is in the center of the plank, then they will not twist so much i guess. Great video anyway, it would be interesting to see the refinement of this design in the future.
With all seriousness. You made Paulin Kunze proud. Amazing work. You made a dead guys dream a reality. I love your videos and especially your sense of humor. TY
Looks great very steam punk feel. If you do another I would suggest connecting the metal bits at the end of the wood. Having the wood on top gives it a high offset rotation point making it perform oddly.

You should attached a layer of leather over the slats. You wouldn't be able to see your fancy cherry wood, but it would help the slats move as a cohesive whole, as one continuous surface, while still allowing the seat to conform, while simultaneously preventing pinching.
when u sit on the chair and it conforms, the surface area of the leather would need to increase so it would tear or stretch a lot
@@hazza2247 yeah, it needs to be done modern material, not leather. Basically a cushion.
Those wood pieces could be taller and also wider, so that they would always be aligned upright with a help of few rubber bands going through. The holes for these bands should be long lines so that the band could move (not necessarily in the outermost panels). I also think one more layer of "fractality" and even narrower thin slices of wood would be better.
@@jankoodziej877 stretch denim? (it can be black, and will look like canvas)
I think the main problem is that the surface of the slats that you sit on is too offset from the axis of rotation of the last stage, and they are too narrow. This makes them want to flop over when force is placed on them, rather than pivot to be normal to the body. Also if they attached 'inside'/between the pivoting metal parts instead of 'on top' of them if would also allow them to be wide without obstructing the metal parts - may need an eccentric shaft to connect the two sides and allow the wood to still be on axis, or just use the wood as the shaft.
I agree that in addition to this, some kind of flexible strap between the boards to encourage them to follow a continuous curve and be less independent would also help. Perhaps a couple of elastic straps stapled to the underside of the boards. An elastic strap may also help reset the chair to a neutral position when you get up.

What a treat to see Cornholio since he disappeared in the late '90s. He must of been spending all this time developing his creative talents.
My 40-year-old bed base from Dunlopillo is very similar to the principle here. In fact, the principle was quite widespread for the high-end segment in the 1980s, before the waterbeds and the mattress construction with foam layers took over the bed market.
When you say "bed base" what do you mean? Is that what the mattress sits on?
One of the first things I learned on mine was that the first layer of fractalness needed to have the pivot point above the butt-contact area. Having the butt-contact area above the pivot, as you did with the wooden slats, lends to a pinchy situation. Mine is actually quite comfortable, though not as beautiful as yours. Good job Eric!
Out of curiosity, how did you achieve this?
@@michaelsorensen7567 if you were to go watch the video, you would know.
@@michaelsorensen7567 What comes to my mind is to make the uppermost fractal pieces a sliver of a circle instead of a semicircle, so that the center point of the arc is above the slat. Pictorially, going from a 'D' shape to a ')' shape if that makes sense
Bravo 👏
Had a thought on stabilizing the planks of the seat.
A guide cable. Drilled through each plank, counter sunk at each end. This will orient the plank into a curves.
That's actually a good idea! It would reduce pinching, since the slats couldn't rotate too far.
You, sir, are my kind of nerd. I started watching you with the restorations, and I love the arcane patent builds. Thank you for being you, and please keep it up.
Nice job! Sitting on it could be more comfortable if the wooden slats were on an L bracket so that their center of mass would be below the axis of rotation.
Yes! They are a bit top heavy and wants to tillt over.
And also that would have better self adjustment and weight distribution.
This bothered me as well. It's not about the center of mass though, but the height of the plane where the forces are distributed (should on the bottom of a slope to self-center, not on top of it)
Yes! The slats should just be combined with / replace the connector rod for the outermost semicircles.
Center of mass matters less than the surface height. It would work best if the top face of the slats was level with the center of rotation.
I am wondering if you can make the wooden planks to have their top surface to be almost where the center of rotation is for the smallest fractal pieces.
Right now when you sit on the chair, the planks experience a big rotating torque, because the surface is far away from the center of rotation. So instead of conforming to the shape of one's bottom, they seem to want to rotate away.
You might achieve this by either drilling a long hole in the planks to put the steel beam inside, or machine a groove from the bottom (which would likely be easier than drilling a long hole).
i can see it, yes.
In this case easier will be to make it in packs of 2 wooden rods fixed to a rotating sector. Looks like a shittification of original idea.
yes exactly
I had the same thought.
@@alexeikolokolcev3232 Sektors win
Cool stuff!
You could try replaing the slats with rollers, and cover those with a "thin" sheet of rubber (which should extend slightly over the sides, helping prevent pinching), then cover that with an upholstered cushion.
That sounds like a Walmart conveyor belt. Not as comfy as it sounds
The cushion itself would defeat the purpose of it's very design since its a deformative surface that your butt makes its own mold.
@@flavourruling2162Walmart conveyors aren't fractal devices. They are not the same.
@@kirbyis4evera cushion isn't rigid enough to make a difference. While it may lesson the effects, because it creates a single surface; it wouldn't be near enough to stop the device from working. It would be like putting a cushion over a hole. The cushion isn't going to hold up to human weight being ontop of it. Rather a human would fall passed the cushions position, into the hole.
@@northernsnow6982 it would render the device moot since a cushion does what the fractal chair does: deforms. And without extra steps.
Congrats on making the heaviest chair of all time. This is one of the most entertaining builds I've seen yet.
That thing is insane, overly complicated, heavy but oh so cool. Great job on building it.
I agree that is it very cool and the job is great. There is another problem: this item is usless, apparantly incovenient to sit. This is a big and primitive misconseption that things should take the shape of a human body. Why? To minimize pressure on body? Again, why? Some elementary thinking should reveal that it is not helpful.
Simply amazing, you are one of the few reasons I keep coming back to youtube, please keep being yourself, never change.
This man is a gem. Just a treasure of past mechanical wonderment.
I just got back from working at a shop in Nepal which had the worst drill press I've ever used. I never thought I'd be so happy to see a well working drill.
I don't think I could've comprehended making something "dangerously comfortable" before, but now I can. Truly a marvel of engineering.
I think having the wooden parts be 'hanging' below their respective sections' center of rotation instead of 'balancing' above them would help a lot with comfort.
Also, I feel you; I'm currently waiting for the operation of my own hernia, which I got doing something possibly even stupider than creating this chair: doing another persons' job, because I thought it would be a good idea to get it done while there's time.
man, i was trying so hard to think of a way to overcome that rotation and I think you nailed it!
It needs to be in between the metal half moons
Either hanging slightly below, or be at the center of rotation (maybe just use wood planks instead of metal bars for the final layer?) with wider planks that "fill" most of the gap between adjacent sections.
I admire your skill and ingenuity. Hopefully you are also inspiring the young craftsman of the future. Imagine what wonders they will create!!! Thanks for posting this video!
Now that's a chair, love the content, your sense of humor, and your honesty, never stop being you!
Nice work. I think the main improvement would be to make it so the surface of the slats (the surface you sit on) pivots on the center axis of the last stage. If they attached 'inside' of the pivoting metal parts instead of 'on top' of them if would also allow them to be a lot wider. Currently the slats being offset from the axis and very narrow makes them want to flop over.
What you are describing is a bed of hydraulic cylinders all connected to the same reservoir. The cylinders can all move freely, but the average has to stay the same.
@@Rudmin I think what he is describing is fixing the wood beams on the smallest fractal:s pivot so it isn't top heavy, and have it be wider since it doesn't have the same space constraint anymore. Idk though since I haven't watched the video.
I think the final stage should be padded cylindrical bars. That would take it away a bit from the original intention, but I think it's a necessary concession because of the imperfection of any such mechanism.
I was thinking padded upholstery and elastic bands between the slats to add comfort and avoid punching.
I enjoyed your sarcasm and silly jokes as well as the briefing and construction process. It was very fun to watch!
Fantastic execution. And now we all know that while a fractal clamp is great for holding material, using one to clamp your seat may not be the best idea.
Well done sir.
I love the problem solving and humour. The only problem with the chair is that the slats are fractal in 2 dimensions only. To get real comfort (and extra pinching opportunities, obviously) each slat would need to be made from 4 (or more) fractal pieces. This would make the seat truly 3-dimensional (like peoples butts). The weight would only need to double or quadruple as would the complexity. :)
tridimensional tiny structures that are affordable and reliable enough for a chair ? humm, i dunno, there is this tecnology called FOAM, it can be salvaged from sofas using a hunter knife or you can buy it like a regular person
Please what the op suggests is ridiculous. What it really needs is four dimensional fractals. That would be a comfortable chair.
But people did have 2 dimensional butts in 1913....
@@talesdemidioful Well that's the soft way out.
@@josephwheeler1 I find it easier to approach this piecemeal. First figure out how to engineer the 3 dimensions before you break out the expense of a 4 dimensional chair (be that in $, complexity, weight, etc.)
This is a thing of beauty and it deserves to be in a museum one day.
Can’t wait for the full body version!
And I’d also like to see it with round wood slats, dowels if like, with metal rings on the ends to reduce wear. Those could rotate freely and be placed closer to each other 😊
Fractal bed to conform to everyone’s unique body shape!
I came to the comments to also suggest dowels instead of square slats
Flatter slats would roll less and tend to keep the flatter more comfortable side against you instead of rolling so you're sitting on an edge instead of a flat surface. If you're concerned about structural integrity, try making metal slats.
The finished chair has a steampunk vibe to it.....kinda cool!
There are chunky metal rods hovering directly underneath the wooden slats already, there is perhaps a little bit of structural redundancy…
@@ShadeTheif Perhaps, but not EVERYONE weighs 150 pounds. That extra beefy construction may come in HANDY if someone over 250 pounds decides to sit in it.
@@juliebaker6969 if you used thin metal slats then they would bend under the weight of a heavy person down to those beefy rods, potentially further increasing comfort.
@@joedingo7022 Thin compared to those 2 inch square wooden slats he used, not thin like made out of tin foil. About ½ inch thick should do it. Steel, or better yet spring steel slats 2 inches wide, ½ inch thick and 19 inches long would hold a grizzly bear without bending.
Amazing concept! I think the wood shouldn’t be on top of the semi circle. I imagine the ballast of a boat, it sits high and wants to tip over. Drill the length of the wood and slide the rod through it and then attach the semi circle portion. Or make another subdivision and instead of wood, brass rod. It rolls and no pinchy-pinch.
I was thinking the same. also, the chair differs from the fractal vice in that the large semi circles don't need to be nested within each other, each can , using a ball race for smoothness be arranged with the largest semi circles to the smallest from outside to inside of the chair. so long as the wooden laths are longer than the width of the posterior, then the height of the metal semi circles will not be an issue.Also, i would like to see a version of this made for a bed, because i have a bad back. we can build it, we have the technology.
That's so cool.
I can't tell you how much I wish I had a fractal vice.
Because of your channel I bought an inclinometer, a bedrock hand plane, a combination plane and several other assorted old school tools.
Fascinating engineering. The most comfortable conforming wooden chair I've sat in used flat wooden blocks interlocked with rope, which I think required tightening on occasion, supported by a solid wood frame. The result was a perfect balance of stability and adaptability.
Like a rope bridge for your butt?
beautiful craftsmanship the integration of the brass hardware is *chefs kiss* i think Ray and Charles Eames would have sold millions of these if cnc milling existed in the 40's and 50's.
I can't stress enough how much I dig your videos. You're a hard worker who does some damn cool stuff and you have exactly the right sense of humor, it fits my own like a fractal vice. I'd buy you a round in a heartbeat, thank you for always bringing us such solid content brother, keep up the great work \m/
100% love this content. Really appreciate it.
A couple months ago a non builder friend of mine and I had a conversation about a wood couch, and something not too far from this is what I came up with. Wood slats with some ability to articulate and deform from metal joints and springs. I figured it would be a ten thousand dollar couch, but that someone could pull it off and make it functional, comfortable, and nail the aesthetic. Lo and behold, you're evolving a test mule in your garage:)
One thing I LOVE about your channel is the lack of music (excluding your awesome intro.) It makes your videos in my opinion the best restoration videos on RUclips!
I only know this concept from scifi books, great work, really impressive. I would say with slightly different materials and additional analysis regarding body measurements, you have built the next generation of high-end seating furniture
Agreed. I'd like it more if it was silent/quieter.
I feel like this concept was perfected in the beanbag chair. Am I wrong?
@@randomd286 Nice thing about the chair is that it doesn't have foam that flattens/wears over time. I imagine there's a lot of other maintenance though.
This is an interesting concept that could probably be improved upon. My personal first thoughts is to go an additional step deeper for finer variation and to pad the slats, possibly a slightly elastic cover similar to the sheet fabric that lawn chairs use. I'd also be interested in seeing this on the back of a chair, given variation in spines, could a form-fitting generalized spinal curve work using the same basic concept. Also, I'd be curious to see how the various slats follow the body throughout various postures, say going from feet flat on the floor, to a partial lift, to a full lift, and with a flexible back pivot how the slats would follow the body through various reclining angles; between a fully flexible system of the 'fractal' pivots, I want to see how a full chair made of them follows the body's shape from a proper sitting upright to a full lie down, with every leg and hip angle between. Furthermore, it'd also be interesting to see what this could do for neck and head rests, and the various movement the upper spine allows. Though at the same time, I think the variability could also lead to disfigurement over time, so much movement that it becomes a hindrance to having better posture; but I also wonder if something like this could be biased with springs to promote a more natural shape for the body, of course tunable due to variation from person to person. It'd be interesting, as there's more variation to people than just height (and thus things like scale of body curvature, specifically the spine, why adjustable lumbar is a thing) but also how people carry muscle and fat, not to mention individual proportions; personally I've had issues finding things that fit me correctly, as I'm tall, lanky, and scrawny, so I'd need a custom chair first of all, but imagine if a self-adjusting chair existed that not only comfortably fit me but also comfortably fit someone who is short, squat, and well filled out.
At the same time, I think a concept like this may work better a 3D surface, as the body isn't flat. Though this wouldn't make this mechanism all that more complicated, just have depth compression along the slat. Similar to other things not fitting me correctly due to my body shape, I also feel like the stick-out of my spine is a bit exaggerated, any time I sit into a hard-surface chair, especially slatted (vertically or horizontally) ones, I'm always very aware of when my spine touches and how much discomfort it causes, I feel like my spinous processes are just abnormally large; which is why a 3D surface would be a better fit, as it relieves pressure from a specific area and rather distributes it along the surface. Though, cushions and padding basically do this anyways, problem is that cushions get hot; especially for someone with heat sensitivity and atypically high body temperature. Gel pads could be a solution, but they're an imperfect one, especially as a lot of them show atypical properties once they're warm, and really aren't as 'breathable' as marketing might tell you; sure, they may be a bit more open, but only along one axis, of which also doesn't see airflow, and even if it did you'd have to push air in to push air out as they're a cube with all but one side blocked, air cannot freely flow. I think the ultimate solution would be to use a compliant form as a 3D sprung surface, yet producing such would require a stupid amount of R&D work, even if the structure and materials are heavily borrowed from other sources.
I just want a chair that forms to my body structure, promotes healthy postures throughout the ranges of sitting up and lying down, and has comfort and breathability. This strange little bench could be a stepping stone towards that, but inherently is complex and expensive to tinker with; though I might take a shot at it with other materials and a modified approach, at least before moving onto other ideas.
Yes, to all of the above
I would argue that the back could be connected to the seat and basically be a copy, or rather the chair would be just flat when not in use, then you sit on one half and the backrest comes to you, this would allow you to sit in any position between sitting and laying down.
A thin pillow attached by the corners would probably work perfectly.
touch grass
hey man i've been independently working on designing a chair (and more broadly a healthier more modern workstation) with a lot of these considerations. if i ever actually make it, ill make everything publicly available and update this comment. but yeah, thousands of years of chair design and even herman millers best shit is still worse from a first principles standpoint than this fractal chair imo.
I love that the first tool used in building the fractal chair is a fractal vice. 😊
This belongs in a gosh darn museum, dagnabbit! This is art. This is not furniture, this is art. And furniture. Furniture museum? Do they have those? Make one just to put this thing in it!
The musée d’Orsay got something like that.
Your content is what RUclips was made for. Fascinating, funny, wonderful.
I like that its smiling at you, that has to make someone a little more nervous to sit. beautiful as well! Great Job!
I wonder what would happen if you tacked a piece of stiff leather or rubber to the top of the slats. It wouldn't move nearly as much, but it wouldn't kinda collapse in the middle either.
I was thinking one of those lounge chair cushions.
I was thinking a special-made cushion where the bottom of it has a ton of extra fabric between each button-point (to the max extent of each joint), and the cushion snapped down with the big metal button snaps, two to a slat. Then you could have a cushion that wouldn't get pinched, and could kinda "accordian" to the shape the chair took- I'd recommend to go heavy on the infill though, since the infill is going to get stretched and crushed a bunch, and you want it staying firm. Think on the cushion height, so that you could still feel the mechanism operating well.
Yes use leather with the addition of slots so that the chair could move inside the slots without folding down into it. Well it made sense to me 🤷♂️😂
I think what will make it more comfortable is to make the slats concave. They seem to rock back a forth a lot because the pivot point is so low. If you make the slats concave you can reduce that distance and make it so the slats auto level as opposed to roll to the max one way or the other. I think that will increase the comfort and also reduce the pinch potential.
I have no idea why this video was recommended to me. I don’t make things, nor do I watch videos about things being made (usually). But it was hilarious and interesting and I watched the whole thing.
Man, I love your work and you being here. I suggest making the wood pieces concave, so they equilibrate in a point and do not diverge to a point where your valued belongings get endangered. Other way, you could have put two wood pieces separated in every last moving piece
"The laser cutter warped the pieces"
*Proceeds to drop every piece, multiple times....
Incredible work! It doesn't look very comfortable but the design is amazing and the result is very beautiful. Congrats!
Agree on both parts. It is apparently cannot be comfortable, and this is great work.
Like most of your content, this thing is *kind of* ridiculous. And also completely, absolutely, utterly amazing. I love your content. Never stop. Ever. I mean it.😂❤👍
Eric you sir never cease to amaze and deliver entertainment and quality craftsmanship that chair is absolutely gorgeous. The way to prevent warping on laser cut parts use cold rolled steel no internal stresses as with hot rolled material
This channel is by far the Funniest and well put together self talk/ sarcasm/ shop talk I’ve seen on RUclips. I thoroughly enjoy the humor and the content.
i love that you used the fractal vise throughout the video ! it really does seem like a very useful tool!
I really do love the steampunk aesthetic! You can never have too many brass fasteners! I think one thing I would change is going from bare wood slats to crushed velvet over the wood slats and maybe some rubber between the middle slat to lessen pinching. I can see why this chair was never made, it wouldn't be very cost effective to mass produce. The best it could be is some sort of luxury custom item. But I think nowadays, you could probably make something like this with modern materials. Cool and fun video, glad I found your channel definitely subscribed.
You saved a tons of money for diy makers! Thank you! And, yes, it was great jobs!
Absolutely love the old patent videos, have an easy recovery and keep up the awesome content.👌
I really enjoy your patent recreation projects. Awesome.
You sir are a skilled craftsman and a weirdo at heart. We are of the same ilk. This video is hilarious and very well done. Keep it crispy!
One of your best videos of all time Eric, love the commentary mixed in, you should have your own TV show
i laughed so hard constantly
Fantastic find and build. That chair is a piece of art.
loved the slo mo shot of the seat adjusting to the profile. And then it was gold.
Yeah, right, "that chair is a piece of art". Sure, why not... taking into account the latest "art", it's just like that painting that was painted using real human sh*t. This chair is the art companion of that painting. Now, more realistic: that chair is a direct ticket to a spinal and back issues in less than a year of using it. It should have never been allowed to exist...
@@Makeloafnotwar sorry, I lack holes to put those in. Maybe you could use them 'cause you really need something intelligent to talk about?
I’m three min in and you‘ve already made me laugh so many times. You make quality videos my man, keep up the great work.
The brass on scale looks fantastic 😍 and no pinching means no teepee for your cornholio 😁
The aesthetic of this piece is really interesting. If you’re in the mood to make another chair how about a steel rocking chair with clawed feet and a mechanical rocking action?
Bonus points if the rocking action connects to gears like an automaton, or generates electricity
This looks really great. You may be able to make it more comfortable if you could limit the pivots with a tension like device like springs or Bungie cords that connect the first or second level half circles
I think the brevity of this episode belies the extraordinary amount of effort that must have gone into this project. I can imagine this ending up in a museum. Is it art or engineering? 😊
A Folly Exhibit
A statement
My only issue with this (besides the pinching and things which can be reduced by connecting the wood straps together with leather) is that it is only fractal in 1 dimension where as the butt would need it to be fractal in 2 dimensions. I don't know if that is even possible. But it is why soft things and not wood are now mostly used for chairs.
It needs to be something like the mechanism used to align the mirror segments in the James Webb space telescope.
you should upholster the wooden slats such that they cover the gaps, than the pinch factor is reduced. It would also look nice and feel more comfortable.
yes that was gonna be my comment as a high end furniture repair technicians opinion
This is as if the fractal vice had a baby with the belt lacer.
Also, 16:27: Good job protecting your forehead from metal shavings 😂
This is the most overbuilt chair I've ever seen, and I love it.
17:20 “so this is cherry wood because, it’s a chair 🤌🏽”
Can’t NOT like the video after that one, you sir have gained a sub
Fantastic! I do think the top of the slats should align with the pivot of the final element though so they just tilt without the forward/backward motion.
LOVE IT!! I very much look forward to EVERY new vid. The generous sprinkling of irreverence and the uniqueness of content make this channel one of the greats. Sorry to hear about the hernia but glad you're on the mend! 😃 Cheers from Sussex NB.👋
You are a true actor sir, I really do enjoy listening and watching to how you present things, well done on the work it's as great and amazing as your actorship! Love it!
This was really neat. In addition to the adjustments suggested by others, perhaps some light preloading of the pieces would be beneficial, so it springs back into a flat position when you get up? Could make it more repeatable and less pinchy :)
Really great to see such a wonderful whimsical chair! I’m glad your recovery is going smoothly. I wonder if some kind of (merely one pivot point) foot rest bolted to the frame would make it even more comfortable.
Is there any possibility to spring load the 4 secondary fractals (like a spring in tension pulling them down, so they want to be centered) to add some resistance to your butt sinking down in the center?
PS: might of missed it, but is that your poor lathe? Did it get refurbished? Did it do all the work? It seemed to handle so much work pretty well.
They actually centre themselves due to gravity! The lathe is still lathing, you just have to work within it's anger.
@@HandToolRescue I have had the same thing said about me. Lol
@@HandToolRescue could add damping grease like nyogel (pretty expensive, might be a cheaper alternative) so that the fractals conform/shift slower
I love how the big scar on the top wood piece is shaped like one of the fractal sections! looks sick
Turned out magnificent! I imagine that if it was only padded somehow, it would/could be _very_ comfortable..
@peacenow42 That would be smart
I can’t wait for the new second channel: Butt Chair Rescue, so many under appreciated chairs out there
I like that the grippers at 3:20 use the same principle
Nice. I can see one thing that might make it more comfortable. Instead of the smallest pieces being half-moons with stats attached to them. make them completely round. Then attach round dowels or rods to them and add padded tubes. Should help quite a bit with comfort.
Exactly what I was thinking, with some period velvet for looks.
Dumb is not a word that I would ever equate to you 🙂. I am always blown away by your skills, drive and knowledge that you express in your projects/ videos. I always look forward to every new video.
I am so jealous……you are such an incredible craftsman…….great job !
If you could mount the slats flush with the metal pieces holding them, the design should work considerably better. The surface should be flush (I think the math term is coplanar) with the axis about which it rotates (or maybe lower? I'm not sure), so that putting a flat object on top returns the slat to a flat position.
Also, I wonder if you could do something similar with tiered leaf springs, the way some (older) wiper blade designs conform to the windshield. No idea how feasible that would be.
I think that the wooden planks should be lower so that the axis of rotation is in the center of the plank, then they will not twist so much i guess. Great video anyway, it would be interesting to see the refinement of this design in the future.
With all seriousness. You made Paulin Kunze proud. Amazing work. You made a dead guys dream a reality. I love your videos and especially your sense of humor. TY
As for how hilarious this design is, as a table vice, it's actually an incredibly ingenious design.
Adam savage is gonna go nuts for this
Amazing idea and execution. Well done, sir.
Looks great very steam punk feel. If you do another I would suggest connecting the metal bits at the end of the wood. Having the wood on top gives it a high offset rotation point making it perform oddly.
