I would stabilize it by adding 4 vertical pieces of wood that connected from the seat slats to the floor. 😎
It's been done a million times
@@betanick14 that was the joke
That's genius
I see what you did there. 😂
That's genius. 🤯🤯
Everyone gives you a hard time for making chairs that you can't sit on because they seem fragile. I think you should make a throne that you can park your truck on.
well sure.. he should.. but that doesnt change the fact that he cant.. becuase hyes clearly bad with weight managment in all forms
He should try to make a da Vinci bridge
One already exists....lol
Now I'm picturing a pick-up sized throne. 🤔
“It’s wants to fall but can’t because of constant pressure”
Same chair same
🤣🤣🤣🤣
actually the joke is "It wants to fall but can't because of constant stress"
same...bzz
Daily dose of memes?

"Is that right Rambo..." 😂 Boondock Saints!
HAHAHHAHAHHAH such a good line
@@John_Malecki Is it dead?
Anyone new to woodworking, just because Bessey sponsored this video doesn't mean that him saying " Bessey is the answer" was because of the ad. They really do make the best clamps you can buy. Especially for the price. I have never had a Bessey clamp fail on me.
You my friend are correct hahha
Having a clamp maker sponsoting a woodworking project is like a fresh lemo ade stand in the middle of the sahara...
The only answer a woodworker can give to how many clamps do you have? Is "not enough"
"I can sit in any chair and snap it in half!" Same John, same...
What makes these tensegrity items so “magical” is that it looks like it’s floating; when more and more cables are added it begins to lose that magic because it looks cluttered. The fewer cables the more magical. I also think you should increase the distance between the underside of the chair and the top of the bottom support to really emphasis the illusion that the body of the chair is not connected to the legs.
John, I think some of the issues may be coming from how the cables are ran through the wood as one cable. I think the way they are ran through the seat back proper allows the chair to slide back and forth. If they were attached to the chair as individual pieces the chair couldn't move.
More importantly the supporting outer cables need to be tensioned when the chair is under load. The way it was produced here the supporting outer cables become slack under load ie. not supporting the load. Applying more poorly tensioned cables did little to improve the situation.
The outside cables don't support the load, they go slack when someone sits down because you're taking tension off of them... The only cable that supports your weight is the center cable, the rest of the cables try to balance the forces. If you imagine a plate on a ball with each corner tired to the ground, as you push on one corner the rope on that corner becomes more slack, while the opposite corner becomes more tense. HOWEVER, your point is still valid to a degree. You can over tighten the outer cables, causing the object to collapse with the smallest tip in balance while it's not under load, but you don't want them to be too slack while under load, or they are not fulfilling thier purpose.
Amazing quote, "Someone skinny! Prepare your ass." 19:03
"Charlie Bronson's always got rope.
He's got a lot of rope strapped around him in the movies, and they always end up using it."
The Golden Gate Bridge had less cabling than that "floating" chair... interesting build though
It's coz it's a first try for them but yeah taking notes from suspension bridges is probably needed here.
Liar.
To be fair though!
Actually there is about 80,000 miles of wire on the Golden Gate Bridge and there is approximately 11 to 14 feet of cable there
@@SodaDaquavion cringe af mate quit bleeding social platforms
"Serial crushed by a big friggin' guy" - One of my favorite lines from that movie, lol.
What helps a lot with these tensegrity structures is diagonal cords. like from the left front down at the ground to the left back of the seat itself, from the left front of the seat to the right back down, etc. i did that on my tensegrity shelf and the stability improved drastically. evan and katelyn have a video about it
“You and your stupid rope” is from Boondock Saints. My favorite movie
"Why don't you make like a tree, and get the f*ck out of here?!"
What is the "SSSSSSSSSSSSymbolism"
Fooken rope*
Are you ohbe kaybe
The center of gravity needs to be centered more over the central cable when someone is sitting in the chair. But the fact that it's a chair means that leaning back places a rotational moment, moving the CG that overpowers the cable tension in the front. a stool would probably work better. Though, it does look awesome.
I thihnk i need to triangulate the whole design, add some widt hto the back and it may help! thanks Puke!
@@John_Malecki
if you make a cable from the lower suspension point to the rear legs, it probably stops the unsteadiness and the lower point cannot move forward.
and was able to learn many of your projects and use in making projects in the netherlands
Had to agree. I would love to see this as a stool as well, since you will only sit upright on the center the twisting/rotation will be minimized
I agree with Schmill. The main cable that holds the weight needs to be towards the rear of the chair. Basically line it up with your spine when sitting. You had it too far forward and created a moment that caused the front cables to burden the load instead of containing the load to main support cable.
I’m a mechanical engineer so I saw the issue right away.
Could you add another main cable from the center straight to the main support of the top... and add tension so when you lean back the chair does not
"What we need, is some rope" "Is that right Rambo?" "Take your stupid ...rope" LOVE this movie!!! "Is it dead?!"
ooooooohhhhh what's the cat's name?
I was thinking Boondox Saints.

Bahaahahaha
As an amateur wood worker, seeing those perfectly square edges after jointing makes me weak in the knees
Dude same I only been woodworking about 2 years now and the two best days of my woodworking life so far we’re the two different days I bought A a plane and B and jointer lol and don’t just buy the cheap ads big box store bench top ones sage up and buy the big 13” dewalt planet and a floor model at least 6” jointer that’s what I have and now it’s so so easy to make perfect square edges and faces that are beautiful and will leave you loving your hobby much much more it’s totally worth it oh and a table saw and track saw and good sanders lol that’s all you need literally
@@TheHomeMaker1 I bought a wen lunch box plane and it does a decent job. But I also bought and had to return a porter and cable 6" jointer. The jointer had aluminum tables and jointing just soft yellow pine for one project on it, huge deep scratches went into the face of the jointer leaving positive matching scratches onto the wood face...
I'm now saving up for a for model, any recommendations?
@@pengwin429 if you can afford it (or save up enough), one with a spiral bit cutter-head. I still need to get one eventually. Probably a Delta, Jet, Grizzly etc.
Intermediate skills world class shop tools. Geometry of cables is absolutely paramount. Love the videos and his personality.
John that is the greatest movie ever! Boondock Saints, and when he says “aye Rambo” hilarious.
185 people cant even build with legos, its amazing how many keyboard professionals have all the answers and opinions, yet you are the one with a successful business and UA-cam channel.. weird how that works.
I know right? It's almost as if other professional woodworkers are actually watching, and commenting on UA-cam videos. We know that's not possible though. Why would people who are actually knowledgeable in a subject they're interested in watch videos on that subject?
That gives me an idea for a full tensegrity dining room table
Not what would be cool.
Wow, I typoed that one really badly.
Make a metal frame covered with wood do some seriously scary you've never done it before cable tension with a lot of weight on top of the table it will be Rock Solid
@@greggarrot8132 I'm in the process of building it got the design done. Its going to be amazing
You are literally living my dream. Your shop, your job, and your creativity are all dreams of mine. I’m wanting to start an epoxy furniture/countertops business but also want to be able to do all kinds of metal and wood work and build different types of furniture. Literally what you do!
Oh and home remodels as well!
@@loganmorris9005 did you ever start the business
Just found your channel today and have greatly enjoyed 3 videos so far... love them and can practically smell the wood... love it!!!
"I'll get my stupid rope. I'll get it. There's a rope right there!"
“I’m f**king fine..... I’ll catch you on the flip side.”
9:40 I can't believe the chair disrespected your time and effort like that! Your commentary is so funny and your woodworking skills are top notch, keep up the great work.
This was so dope , you guys should Build another one ! I wanna see the whole process of building a fully stable one where you can sit at any angle
Awesome job, sitting in the chair may require some mental focus, Best line in the video "Someone Skinny prepare your ass" John you said that right as my Girl Friend walked in my computer room.
Boondock Saints. The first one. I love those movies.
3 years later, seeing you without your shop shades really looks different.
YES! please do another one. I am also a big guy and would love having a chair like this.
especially if I built one myself.
Pretty nice work, John! 😃
It may have problems, but looks really nice!
I don't know what to do to fix it, but next time start with a cheaper wood as a prototype. 😬
Anyway, stay safe there with your family! 🖖😊
I can't recall ever laughing with someone sitting in a chair!
How can are there people not loving this content. Keep on going man! love it!
After watching your vids I finally bit the bullet and used some nice wood in a project, built a black walnut toolbox with a thick poplar handle (not the strongest ever I know but it seems alright hahaha) but wow!! I still have a ton to learn but honestly it looks really nice, Im so pleased! Thanks for the inspiration man
What about a tensegrity hammock, where each “arm” that holds the hammock is a tensegrity element?
I have a Boondock Saints movie poster in my home theater. One of the best movies ever.
and I believe it's "...stupid fuckin' rope!"
Of course! you have to make another one !,Cheers from Toronto Canada!
Love the look. The only way I see fixing the forward/backwards rotation is to move the center of gravity back as you said. Boondock saints is one of my favorite movies.
Boondock Saints!!!! Love the ass clownery!
Nailed it !
As a project it's quite nice. I've always loved this kind of "How the hell does this work?" things.
My thoughts about the design are, that the connection between the base and the chair that supports everything should be more on the rear, this way the main tension rope goes with the center of gravity. Probably it's enough to invert the orientation of the wood hooks that he made for the main cable.
I've never been this early to the party, but I'm psyched about this build! Ready to learn some more about real woodworking!
“ Boondock Saints” One of my absolute favorites. We can officially be friends now John.
Can we get a "Fancy as F&*%" shirt?
I will add it to the idea sheet !
You could benefit from taking some physics courses.
The main issues you're encountering are coming from alignment. Your loads are varied, but your cabling is not, it generally follows one direction which is obviously weak and unstable.
That is not to advise perpendicular alignment. I recommend short interval curved parallel alignment. Consider compression, ductility and the engineering benefits of shallow, long span lateral and vertical arches when designing your pieces.... Good luck.
For stability tighten the front wires a lot more, bringing the chair forward a bit. Then how about, adding wire straight down to floor base, as oppose to two that you did and add tension spring to the center tension wire also to absorb some shock?
Very nice build. It looked like some of the wires you built were able to slide through the wood. I would change those out were they were unable to slide. Also I would run wire from the back piece at the lower point that has the main wire (the very first wire that you built in thto the vide) to the front legs. Hope this helps.
Boondock Saints. Best lines in #2:
Everybody shut up! Romeo is crying!
And
"You look like you've seen one up close ". 🤣
Big guy problems with chairs, my life story 😆 I'm with ya John, great build and video!!
Getting crazy wowsers amazing video as always John keep up the great craftsmanship and hard work my friend keep making
Gotta love the 'Saints'!
"Oh, is that so, Rambo?"
Yood video! I am impressed that it is much harder to get it to work than I thought it would be. The flexing of wood is a problem. That might be why most are made of steel instead of wood.
"Charlie Bronson always has rope" haha. We would get along for sure.
Hey I know one like might not be much but what ever helps supports what you love I’m glad to do it and I love wood working myself
"Go to your home!" Gotta love the Happy Gilmore reference!
To fix the rocking back back problem you can run a hole from the base of the seat "arm" (where it pokes out from the rear vertical back support) and twist the 2 wires together and inlay them into the front arm of the base to anchor them at the very bottom where the chair sits on the floor
It’s a shame that I haven’t long discovered your videos/builds. I like you and think you are pretty cool. I would like to see your interpretation of a floating shelf with a hidden compartment? Something like we have not already seen on youtube, I’ll continue to catch up on your videos whilst you figure something rad out.
"what do you need the stupid rope for" lol great Boondock Saints reference!
Excellent work!! 👍
Maybe a second wire like the first one you installed towards the back can help stabilize the tilt forward to back. Since it’s all about balance, perhaps more balance between cable in opposite directions of tension.
Run the play until it is perfect!
Looking forward to chair version 2.0
This is sweet. i still cant wrap my head around whats keeping it from rocking backwards, at least to the point where the lower mounting cable mounting point (bottom of the chair piece) goes forward and its the back of the front vertical support. I'm sure its simple, but its some kind of optical illusion that I can't figure out
Nice idea i would try adding a tension line just under the front of the seat to the top of the pillar to stop sway back
I may have been rooting for a ca-chunk moment there at the end... LOL! Killer build John. Tension structures always start to look a little radio tower like, so I think you're on the right track.
Can you make it with the center of gravity back further like you said. Also what about having 2 of the center (looking from above) spines? one left and one right. So there would be 2 center cables suspending the top to the bottom, and way less cables to support the side to side sway.
That is the most beautiful carnival ride I have ever seen.☺️
I admire the maximum clampage greatly boss!
I believe if you were to add a second line to your first and 'main' attachment point on the 'base' and connect it to a point further back on the 'floating' piece (basically a triangle with the top at the metal anchor), you could eliminate the majority of that sag that occurs when you add weight. Additionally, you could add a couple tension strings which begin on one side of the base, go through a hole on the floating piece, ride up the length on the other side, then come back through another hole near the top and attach back to the original spot on the base. This could add an element that resist the side-to-side deflection.
"You and your stupid rope" - Boondock Saints. Great movie indeed, in my top 10 for sure.
[Splatters Cat on the wall.]
Murphy : I can't believe that just fucking happened!
Rocco : Is it dead?
this is very cool would you ever build anything from hemlock i know its a strong wood and it kinda looks nice
Wicked idea and execution... I have to see every stone, pound & ounce of your hefty frame suspended in one of these chairs. I recon it's going to take some scaffolding-handrail bent with a mandrel and some slightly thicker gauge wire!
Dude. I just found your videos today. All I have to say is..... “I’m not worthy!” I love your vids man.
Could you reverse the base and chair arm components? So that the Arch comes from the back of the chair from the ground and vise versa? as well with realigning the center point i think that would help.
I know I'm two years late. But "is that right Rambo?"
"Alright get your stupid f***ing rope!"
Could you replicate the main thick cable, with a 2md cable going horizontally back.
In theory if that was in enough tension it would help the lean problem... maybe
The upper chair piece's main support cable attachment could also be wired to the same rear outrigger points to prevent the back from torquing forward. Might work
soo this was the first video i've ever watched of you. and oi gotta say. i like the way you talk freely. like every other youtuber at this point is holding back because of ad revenue. but you just shoutout sponsors every 5 minutes, and honestly i dont even mind. at least your sponsors are relevant!
@John Malecki Why not try to put another short cable in the front? the same way you supported/connected the top and bottom halves with the metal rod in the wood.
Try a second main support from same bottom frame top point to the middle of bottom curve of floating seat part. Maybe even lower on the curved area.
IT WAS A FIREFIGGHHHTTTTT! great movie. Great floating chair
This is sweet! I feel the not being able to sit in delicate chairs. Another great creation.
Base rear most point cabled to the seat lower bend will add more rotational support. Currently the seat lower bend to the rear side anchors is what is trying to stop your leaning back rotation but doesn't have a good angle for front/back directional support as most of its strength in in the left/right direction. The closer to horizontal the cable the better, Might want to even consider a little upwards hook to the wooden structure to elevate the new cable anchor.
I'm paralyzed from the waist down it would be awesome if I had a realtor that floated. Awesome chair and great video
you got it right at the end when you said your cent of gravity is to far forward. Plus the wood is flexing under the weight which is allowing the back to dip down. make it have 2 of those center cables.
boondock saints.. lovley movie :D
jealous on your diffrent type of wood u getting your hands on! cool builds keep up the good work!
//from a swedish carpenter.
Could you extend the arm piece thats directly under the chair and run two of what you currently have as centre supports? You'd still have to counteract a sway (make a feature, rocking chair?) But it wouldn't pivot in the same way. Essentially your central support which is the main weight-bearing one become two and is some kind of quadrilateral rather than a just a line.
How about adding a secondary tension point behind the back of the chair? Meaning the central cable has two points pushing upward, one in front of the backrest (the one that's already in) and one behind the backrest to relieve a bit of the spring when sitting back. This would in theory also mean way less other support cables.
I think the key to this is to think of the cables on each corner as a 3-legged stool, for a total of 12 cables (13 if you count the center one). Also, think of the base as a 4-anchor-point plane, and the bottom of the seat as another. Now it's a simple task of having 3 cables come up from each bottom corner, to the seat corners directly above and to the left and right (i.e., not the far diagonal corner). Also, engineer some sort of tensioning system into each of the 12 cables, such as turnbuckles, hidden perhaps within the seat and accessible from the bottom. Now those 12 cables, 8 of which are on a diagonal line to 2 other corners, will provide the rigidity you're after, without sacrificing too much of the 'invisibility factor'. And if it does, simply start subtracting cables, starting with the straight vertical ones.
Yes make another one... I think you need to approach this chair with the first tension as you had it, but then a second tension in the back for the sway
Love your videos! More and longer videos please.
🙈 I was a bit scared not gonna lie lol great job!
I can't even put together Ikea items, yet I can't stop watching this channel!
After searching the comments I was shocked to find that not a single person had related this char to lieutenant dan. So I felt obliged to do so.
The Boondock Saint's... best movies ever... 'you and your stupid rope' 😅😂😂
Making the verticals spine of the back deeper (in relation front to back of the chair) may gain you space to move the center point of balance further back. The edge of the chair may need to come forward beyond where you had it as well to get better COG. It makes footprint size larger but could gain you better access to fix the leaning back balance. Also, since you’re doing a 2.0 (I assume?) consider adding guy lines to each corner of the seat and run outward from center rather than straight down. That may help counter the leaning back motion. Better yet(?) you could cross brace each wire point = Run from the center line of seat to outer section of the base and from the outer edges of seat/lower back slat in to centerline of the base.
Fantastic video John!
Very cool. Definitely make another one that is a chair you can actually sit on for a while.
Can you put one cable on the bottom of the back to the end past the feet that will to the forward rotation
