If you like this table you're going to find this incredible Floating Cave Table to be just as cool! czcams.com/video/WUwjq1zZCis/video.html
John Malecki could you please send me the measurements you used im going to make one out of red oak
Can u send me on the dimensions please I would love to try this
Since you use Fishing line u could also use Lead weights. Weights with slots to 'grip' the line and then pressure fit the weights into each end as a counter sunk insert.
I like the table. Well done. Have you tested the weight capacity? 👍
I Love your videos and channel 💞
Use near-invisible fishing filament. Takes the magic up by a notch.
My thoughts exactly
Seconded!
I'd do the outter 4 in 20lb mono and the center at 80 plus braided wire in black for flex. I believe mono would stretch too much for the centerline
I tried this with 200lb mono. The stretch makes it very difficult to tension it evenly. Tried again with 1.5mm steel cable and it worked much better. To get the table stable, it needs a lot of tension.
Not stable
I appreciate how the sponsor segment lasted 4 seconds. Not 4 minutes
Made up for it with 6 commercial breaks.
@@seanemclean get premium. Its worth it just for that. I completely forget there are ads till someone mentions it. You also get google play music. It totally worth it.
ill only get premium the day we can listen to youtube and close the app.
@@lewishayward994 just use ad block. These guys get all their money from sponsors anyways
Lewis Hayward you... can, that’s another feature of premium...
If you look up Buckminster Fuller's Tensegrity you'll see his designs use the tension lines in the shape of triangles. So to stop the "wabble" you can add lines from the bottom center post down to the base points and from the top center point to the top points. Tighten it all up. The center line will need to be strong enough to hold the weight of everything put on the table.
This is a very nice table!
First I've seen a mention of Buckminster Fuller on these videos, although they may use his term "tensegrity".
if you know someone who studies civil, mechanical engineer or architecture ask them to know how much it could lift (they would know some materials) and where you can put the lines. A friend of mine did to his brother and he calculated it to make a very strong table. it can stand a person and doesnt move.
I mean, shouldn’t you just be able to tighten up the middle one and everything should be fine?
@@dannypal5385 those give you stability
I just learned something😁
This is like the perfect whiskey table, it automatically swirls it for you
Underrated comment
@@MagnumTimr seriously this John Watson is an undercover genius
Then pours it down lol 😂
It takes a certain kind of genius to turn a bug into a feature. Keep up the good work, sir!
@@MagnumTimr still really underrated
Should use black thread. They almost disappear enhancing the effect. It is why magicians use thin black thread to make things float and move.
My thought was to use transparent fishing line. I now think black is a better option.
What would be the most durable line that is also viable for being unnoticeable?
@@FavoRitsu lines from fiber optic wire could do the trick. They are very tiny and durable at the same time. But it will require different mechanism for tightening, as this lines breaks when folded.
@@PavelFilko honestly if you are talking durability and strength you'd probably want nylon (e.g. fishing line) or thin steel wire
Niklas Mertens
Dark fishing line, then?
could have also used steel wire and guitar string knobs
Yes. Three tuners could be fitted under the base unit, so they wouldn't be visible. Although nylon wire/string probably looks better than steel because it's less visible.
great idea
Same thing I was about to comment, could have used bass strings to tie in the guitar theme
That's what I was thinking, as well. Could probably tighten the guy wires a bit more then, as well - make it less wobbly. Although I worry about steel wires biting into the wood and cutting through corners.
Steinberger makes double ball strings
Wish I had a workshop like that in the backyard of my house -- can't wait for this madness to end so overtime will pick back up.
Awesome video!
18:58 The Doc Brown running down the street in BTTF 1 yell!!!! :O :)
*TopFineWoodworking. Com* is a fantastic website about wood working. I took various classes as well as finished a one year diploma in carpentry at a local tech college; this is much better than any book I worked out of during those lessons. It explains everything regarding woodworking as well as complements it with helpful photos.?
Love how excited Sam is at the end
I would honestly never get tired of looking at that if it was in my home. Really cool build featuring a crazy concept. Nice work John
available for purchase?
I feel some real Andy Bernard energy from this guy.
Lucas Pessoa Pereira I don't see it. It would be like Dwight because he makes tables.
Just found this channel and oh my God that workshop is amazing. Clean, organized, and so many great tools.
“Because I saw it on the internet, I’m obviously capable of doing it.” Haha!
That table is so cool! Stretches the mind to try to figure how it “floats.” But very nice looking!
The center of gravity is in the center of the table where the middle wire is. The entire weight of the top part is pulling downward on that middle rope, but the base on the floor is holding it up. The 3 wires on the sides of the table is just to stabilize it so it doesn't wobble too far away.
OhMyGulay thank you
@@Pwn3dbyth3n00b "The 3 wires on the sides of the table is just to stabilize it so it doesn't wobble too far away." It would fall immediately because it's an unstable equilibrium. Without those wires, it would be like balancing a pencil on it's point. But the rest of the explanation is written quite nicely.
Edit: Because the table is not symmetric, the center of gravity is not in the middle. So it's not even an unstable equilibrium.
Looks wicked love how you used the dowels to hide the fishing line while also making it look like a feature great work and craftsmanship
Best part: your true excitement for a job awesomely done. Rock on!
John and Sam crushing it. Very cool build.
Whoa was it just me who thought it was sketch how close his fingers were to the tablesaw blade?
Not just you, that was pretty sketchy
i noticed the saw blade was the other side so i didnt realy think it was sketch but if i didnt notice the id say that sketch
other people are more nervous of people handling knives than the person handling the knife.
he trusts his saw. Now when Michael Reeves gave a robot a knife and had it stab with a lot of speed and force and not a lot of control based on motion, that was dangerous.
You always use a push block, never your fingers. No matter how far you hand is from that blade, you’re putting yourself in a bad place.
You would have shit watching me cut 1/2 wood width wise on a table saw. Very dangerous if you dont have complete confidence and a little crazy in ya.
I absolutely love this video. In addition to "figuring it out," I appreciated that you're simply being yourself. Great work!
I wish I had a friend like John, such a hilarious red blooded American.
Random mustache at the end. Nice.
Subscribe for next week and see why hahahaha
Looks like he's channeling Instructor Earl from BRCC 🤣
@@John_Malecki lol anything to do with the artwork at 19:29 ? Classic.
I saw the Ron Swanson photo on the wall......the mustache approved!
Makes me want to commission a peice, because I wouldn't be able to even make this. Awesome work!
Very clever. Imaginative and stylish too. Im going to try 3 printing one. I love how it actually supports objects on top of it. Fascinating piece of engineering.
Love it! I just love seeing these crafts come to life. It's freaking cool!
Very cool, like how it turned out much better than the first mock up
"squirrel is delicious ... but also" this randomly popped up in my recommended and it's been 16 seconds and I'm already invested
I hope those 16 seconds were incredible!
Although I have seen small toy-like tables like this before, THIS one rocks! Full end table sized!! Nicely done! You need to sell these!!
It looks amazing! And walnut was certainly an excellent wood choice for the looks.
I love this channel. Bloody fantastic seeing some ex footy player going for a complete career flip like this. I only know one other and it's an ex AFL player who now works as a civil engineer. Will have to show him this channel now.
I actually looked up Computadora. Now I'm thinking of a computer wearing a fedora.
FYI: Fedora Linux is a thing.
He pronounced it horrendously
yeah that was very cool - nice finish - real craftsmanship here.
That's friggin awesome. Well done!
Petition for him to do a collab with Bobby Duke Arts
yessss
Hey. The reason your table is wobbly is because the side strings go straight up and down and describe a square. That's always going to want to shift sideways into a parallelogram. If you add another string to each corner and turn the top 60°, then you could have the side strings describe triangles. Under the center tension, they would not allow it to twist around like what you have now. It would still float -- only better. It would probably be as strong as a normal table -- especially if you went with guitar strings.
I'm drooling right now. I love that slab of walnut. Oh my Giddy Aunt, it's beautiful.
Wow!!! Awesome table. You should replace the string with gold or brass, even silver small chains. Would look stunning against the dark wood!
I'm pretty sure you could do a proper, usable table by having this kind of system, but like, times three
FYI, the term tensegrity was coined by Buckminster Fuller. While Fuller did not create the first tensegrity construction he popularized the term through his writing and went on to design many tensegrity structures.
It's not a tensigrity structure, though, as it has non-string elements which are under tension. In a tensigrity, all solid elements are under compression.
I am really impressed by that. Never seen something like that done and I watched a lot of word working videos. Congrats on getting it to work.
He's a master of tying knots. He's the knot master. When anyone needs a knot tied they go to him
Yeah right
Yeaahh right
He's the king of the trees. He's the Tree Meister
Get real
One might call him Captain Tyin' Knots
Great work John! If you make the top and base different sized equilateral triangles, it would likely be slightly more stable and prevent the racking/swinging motion under the same amount of tension. Also, if you can find something that has less give than fishing line, that would also stabilize things as fishing line does have quite a bit of flex even at that test.
Ooh, MARK II
"Don't waste the wood." I hear ya! Especially walnut over here in Europe, that chunk of slab-thing you started with would cost me several hundred USD. Crazy.
WOW!
I have a bunch of Black Walnut growing on my mountain.
Got some cut down and naturally drying now.
Is it just me that could envision this made out of guitar parts?
With that said, I'd love to see what you could do with a couple of acoustic guitars!
I had the same reaction. I've got some leftover bass guitar parts and lots of spare strings. Make the short center string a fixed length and the tension of the 3 corner strings can be adjusted using bass guitar tuners.
Awesome build man! Such a great fusion of cool science stuff while still keeping it classic with the woodworking
Last night watched that Australian guy use a chain as that tread..it's become trending about this floating table..just waiting for your video and this is it.. 👍👍
I am glad to see you're doing videos that you really want to do now.
Thank you my Leaf !
@@John_Malecki You are welcome friend. You seem to having a lot of fun and it comes through in your videos.
This was really awesome to watch. As soon as it finished, hubby said "$1300". Lol. Marvelous job guys. Can't wait to see other adaptations to the table. You could really market these!
You guys have some fantastic woodworking skills.
This guy is a nut he needs a Netflix series 😂
I would say it's the other way around: Netflix needs a series with him.
I would most definitely watch that
You can never be more american than an old football player who loves guns and makes things in a giant workshop WITH an american flag
freedom, you forgot freedom!
and cannot tie a knot
@@jensegedalsrensen1632 even more American- "I have people for that"
Arlington is full of people that prove that statement wrong......
Love it!
So awesome! Thanks for making this.
I dig your channel and love how organized your shop is and that it is also matchy matchy!
Now that's epic
God damn I drew this in my book in December almost identically after seeing the Facebook video about the tension! Now i'm going to have to try it for definite!
I like that you are so comfortable in your knowledge. Very cool table
Looks good . I may have went with bronze/copper chain with turnbuckles for tension and more points on the outside to make the table more resistant to wobble.
IKEA be like: Wright this down
Just to be correct
*Write this down
Not funny at all
Thanks John, there goes the next 2 days of my life. Fire up the coffee pot and sharpen the pencil its going to be a long night. Kick ass project!
hahah yes Mark !
this was amazing. well done. I think its time for another Epoxy/Resin build, please!
They’re coming ! They take forever to dry! Haha
So freaking cool! I might have to take the rest of the day off from work so I can binge your last few projects!
This is just the more american and table version of Bobby duke
Haha.. i'm from Indonesia..😎, so entertaining.. Bravo this project! 👍🏼
I definitely will make one. Thanks for sharing all process
That's a real work of art...beautiful!!
As a fellow woodworker who enjoys the craft as much as any that love the beauty of real wood, I have to say I am impressed with what you created here as an experiment! You likely brought "Tensegrity" to the attention of many that may never have known about it otherwise! Kudos for that!
Now I have to address something I watched you do repeatedly in this video, and it made me cringe. You likely have quite steady hands, which allows you to be more precise than most in this type of work (I do myself also). That said, it is not good to take risks that can do irreparable damage to your best tools; your hands.
First of all, your tablesaw work in which you use your hands to push the material through with what looks like no more than two inches clearance from the blade for your hand. I've seen many woodworkers lose fingers or parts of fingers doing that. Steady handed though you may be, you never know when something might happen that would cause a disastrous severance of a digit. My own Pop was distracted by a coworker while operating a tablesaw, and lost his right index finger because of it. I myself am a very careful individual around such heavy woodworking equipment; keeping safety foremost in my mind. Because of this, at the age of 63, I still have all of my digits, and they all work quite well. The fix for this is to use push sticks. I can give you plans for making push sticks, and even a fence rider push handle that will keep your hands safe.
The second thing is when you were drilling holes in the dowels, using your hands in very close proximity to the business end of the drill bit. That is no less dangerous than the previous thing I noted. The bit could hit a soft spot in the wood and punch through your fingers, or even your palm, due to the pressure you are using to work the drill! Very scary! You should use something to brace the dowels, holding them firmly in place other that risk your hands like that.
I'm only calling you out on this because I care about my fellow woodworkers, and I want all of us to stay as safe as we possibly can. Yes safety rules take a little extra time to follow in your work flow; however, following them is proven to save you time in the long run, because an injury will take away time you could use to do what you obviously love doing.
If you wish to know how long I have been working with wood, I now have 51 years of experience, as I started at the age of 12 in Wood Shop Class in Middle School, Virginia Beach, Virginia. I am also descended from a long line of woodworkers on both sides of my family. My Grandfather on my Pop's side was a furniture builder and cabinetmaker. My Pop was also in woodworking, and he and I worked together in the same company, doing what we love. It is my chosen profession, and I put myself into my work, as I love creating pieces of real beauty from beautiful wood.
Please sir, I respectfully ask that you take extra care to stay safe in your woodworking environment! In that way, you will extend the time you have working with wood, as you obviously love to do.
Cheers!
I was literally thinking about a wooden version of this thingy!
try building it on it's side...seems like it'd be a more stable one man job
NOW ......challengeJimmy DIRESTA to make it in steel😳😳 better yet do a collaboration!!
Looks great. I'd imagine that you would have to put in a tension tool to tighten up the string as it stretches.
I love your mental 3D vision (otherwise known as spatial awareness). Your enthusiasm is infectious and your vocabulary is fabulous as well. YES , I love watching your videos, John!
That is amazing looking table will certainly be building one of them. options of making a different shapes too great video
Dude, You’re the brother in law every guy wants to have around.
I would love to buy a set of plans if you ever make some up. Love this one.
Your mad comfy with that saw stop!
Like gramma used to say: "if you don't know knots, tie lots." Nice work.
We call that a cut knot
I wonder why this design is so popular now. Not just tables but something that goes on an office desk that looks cool.
We had to make similar items for our engineering class years ago
Because Lego
OMG this is amazing! Such great precision and skill 👍🏻
I am so happy to have found someone who seeks the tangents in life as I do. Left-right-up and down are okay for some people, just not for me. And your friend, Sam totally rules his own world. Thank you'ns for showing me a table that I must build. Your explanation of the project as you went along is like art in motion. Take care and stay healthy.
That was EPIC! Nice work, John. One thought regarding your knot choice: a taut line hitch might have been a better option. It's adjustable and used to tighten tent lines to stakes. Your Boy Scout assistant should be familiar with them.
Hahaha i'll let sam know, great input!
Man every time he drilled into the ends of those dowels I wanted to look away. I’d have a new fingerprint right now if I tried that
Such a delicate but gorgeous table!
That looks gorgeous!
I only wish I had the brain capacity to understand all that you did in this video.. alas I do not... I look on with wonderment and a hint of envy but loved every second of this video!
Try watching it several times till the penny drops, it's worth it, oh and find a buddy to help, it's got to be worth trying hasn't it?
@@catherinemalcolm8125 after rewatching it and thinking about it I think I actually figured something out. With the power of one brain cell and a half eaten quesadilla I've done it.
Google tensegrity for more info. The center line is what holds it up. The top's center of gravity is way off to the side so it is trying to fall to that side. The outside cables stop it from falling/twisting.
You don't want a table like this if you have cats. Might be funny though.
or if you ever set your beer down. lol
Good job guys! Awesome workshop and tools too. Applause
Thank you for fulfilling my wish to see it bigger
"Less thinking? More thinking? What do you think?"
Any way you could put the plans out for purchase. Would like to make this
Greg Kozma dang you Greg! Purchase? Now we all have to pay for the plans! ... LOOK! JOHN!! YOUR TABLE'S ON FIRE!!! (Psst! Hey! Greg! Quick, while John is distracted...can you memeograph me a copy?)
Haha I made it up as I went. So no plans my friends
You could also make a mechanism to configure side thread tightness, so it wouldn't be so wobbly. But the idea is mind blowing.
Very cool. The adjustable bolts was brilliant but I'd have gone with monofilament line instead of string.
What if you did a string to each opposing corner like an “X” to stop it from swaying and twisting
I was thinking much the same.
Rotate one triangle 60 degrees, and have two lines in a V going one each to the opposing points. It would probably stabilize that top nicely.
it would stabilize it but it would take some of the mistery of the table in my opinion
I get the whole fishing line/floating thing but I feel like it could look really cool with chain.
It's already been done.
❤️ YOUR WORK AND THE WAY YOU BRAINSTORM !!
Make more anchor points to stop that wobble. Use an extra two lines from each point across transecting the shape of the object (8 more if you wanted an octagonal table for example, so in this case 3 total) and tighten them for stability.
First time seeing one of his videos. Within the second sentence I found my people.
We were meant to be
When I have to thread a string through like a drilled "not really threadable hole" I use superglue to stiffen the string.. that kind that use reactive spray so I dont glue it to some random bodypart. :)
I love that you say "I love wood", starts cutting... then "lets do some thinking..." Just like me :) First the idea forms.. then how to cut... then back to the idea and .. hm.. back to thinking.
Nice way of utilizing tension physics do be wonderfull
Well I'll be damned. I thought it was trick photography at first! The damned thing really does appear to be "floating" ! My hat is off to a refreshing and remarkable build. Great job!
My brain can’t wrap around how that is possible
All the weight is on the center string. so it's all downward force. The other strings are in tension just to prevent the top from moving and shifting its center of gravity to anywhere else but the middle string.
It becomes apparent @4:43 when he pushes down and the 3 outer strings go slack (which means they aren't providing any upward force). Gravity pulls the tabletop down but the center string pulls against gravity, upwards. The C-shape design of the tabletop creates the illusion that it's floating -- if you imagine cutting off the table-top portion, just below the 'Y' joint, you'll see what's going on. Very clever illusion!
@@MikkosFree So magic. got it.
The center string is holding the platform up. The outside strings are used to balance the piece of wood from falling over... Everyone is making it way too complicated
