Mathias I'm a Big fan of you. I always watch your videos. I just want to point out that the Sawstop would only stop if you were touching the metal. I don't think you were so there wouldn't be a reason to swear.
I messed around with geodetic domes backin the 60's and found that the angles have to be exact. When you said that the blade angle was close enough I new you were in trouble. You are the best. Thanks for the all the interesting and educational videos.
Awesome work! You mentioned about your dislike of tape as clamps. Here's a suggestion: Use the masking tape to line up the pieces (just like you did), then use a 1/2" thick rubber band that they use to hold broccoli stalks in a bundle. Secure the rubber band around the outside of the 5 piece pentagon. The pressure will be exerted inwards which will hold the pieces in place until the glue dries.However, this will only work for the pentagon pieces. Once you assemble the 12 pentagons into the sphere, use large rubber bands (cut from a car tire inner tube). The pressure will keep everything nice and tight but it will also allow last minute adjustments until the glue sets.Excellent video and excellent RUclips channel. I am now inspired to try to build my own.
Matthias Wandel very impressed with your work. Being a high school student, this woodwork has really caught my attention... thanks again for being a reliable uploader. peace!
Dude, you do some of the coolest stuff. I learn engineering just by watching your videos - the use of tape on those glue ups to provide compression through use of tension was just awesome.
man I needed this video like a month ago! I built a 1080 piece chair out of trapezoids fashioned to form equilateral triangles but I couldn't get the miters right to do my original design, props to you :D
That was a nice surprise! I will instantly have to fetch my own old paper-polyhedrons. I made a icosahedron from wood almost 30 years ago, but that didn't turn out as well as your dodecahedron-based geodesic, because I had a very cheap table saw. Btw: I assume, that your old one at 0:05 has been made without the double cut you show at 2:15.
This would be the start of an awesome series of lamps. Now I just need to figure out a jig to drill out most of the material from the center each triangle.thank you sir for keeping me busy for the next week.
I would be very impressed if you scaled it up to make a roof for a gazebo . This video is impressive by itself. You make it look easier than it is. My wife buys metal gazebos from Target and the never survive the winter winds. Love watching you work it a true pleasure.
I have been a follower on my old account since I first created it in 2010 and I just want to say you are one of my favorite youtubers so keep making the videos thanks
The whole time I was watching, I was wondering if he was going to do the "stand on it" test. Matthias, you did not disappoint. Also, as a math teacher, polyhedra make me happy.
Thanks for sharing this Matthias! As you know Dodecahedron is one of the sacred geometries. And you may also know that, if you were to build one big enough for you to sit inside comfortably, you will be *inside a sacred space* but did you know that if you were to meditate inside this 'Sacred space' , something strange, something magical begins to happen!
Always fascinated by your work, Just think in 10 years I'll be watching your next video where you have figured out how to make each piece using dovetails
Mathias, Merry Christmas to you and your family . This video inspired me to make three way speakers, 3 domes on a base. I used a ring with sand paper on the inside to sand and shape the domes round. These are floor standing speakers using JBL studio master components and crossovers . I'm planning a set of dome speakers made out of limestone, they will look like snowmen. I wanted to thank you for all you expertise and videos , especially this one. My wife extended you this complement: "His ,(meaning you , as I watch your videos), skill and craftsmanship makes you,( you is me her husband), look like an idiot". It's true. Still I love her after all these years. Thanks again.
Great to see you make that thing, I've build a similar one at the art academy three years ago and still use it for storing small tools and some other special items :) Built my own laser cutter some time ago and now can cut thin veneers with it, so I make these shapes out of very thin wood which makes it easy because I don't have to use miters for the thickness :)
I always like your work and your working style.its very nice and very professional and also its very helpful for those peoples who want to do something different and according to the natural requirements. Thank you sir Mushtaq mughal
Nice. I can imagine those miters are very hard to get right - once I made a world map in the shape of dodecahedron and it required quite a long time to fine tune the cuts. But the result can only be beautiful.
frank howarth I'm not so fond of the "sculpture as a a birdhouse". I guess a birdhouse is the new "ashtray" that kids always made from clay, for lack of a better "use" for it. I'd be more concerned about weather resistance for a birdhouse.
Matthias Wandel What better "use" is there for this piece you made? because for me a birdhouse it's just as good as any other use you could give it. If birdhouses have become dull proyects, what better way to put some style and expertee on them than making something like this into one? I do see your point on this being somewhat difficult to make waterproof, but I'm sure there is a way that this could be done, and i would love to hang this piece on a tree and see a bird flying out of it. That or play D&D....
The mathematical shapes are one of the things I would love to make in the shop, but the angles worry me. I will attempt again when I have a hole in projects. Awesome work Matthias!
I love when you show that you really trust your work byt just jumping/sitting/standing on your products You can really say that you trust your math and geometry! ahah I remember building these complex shapes in middle school for tech drawing, and just cutting and creasing the paper then glue it was a real mess on most of the complex shapes
I only knew that name through Marc Maron's podcast, although he pronounces "B" differently ;) Thanks to your comment I can now put a thing to the name, so, thanks for that!
Fuller once announced that he could cover New York City with a dome, for the cost of snow removal for ten years. He said the year round temp would be in the 70s F, so no heating or cooling costs for the residents. He was still on campus when I attended SIU-C, but I never thought to go meet him.
Nice job. I would suggest you try a silicon caulk to adhere and to fill the cracks. You may also benefit from building the pieces around an inflated balloon that you could pop when completed (or if you glued the outside of the balloon it could remain as a smooth inner coating of your dome).
Great job, Matthias! Did not expect that ending. Also, this video is exactly what I needed. I'm wanting to build fence post caps and want them to essentially be a four sided pyramid. They won't come to an equilateral. But how would I go about finding the bevel angles for each triangle?
Inspirational video as usual. Small point: I believe that SAW STOP would not have stopped (i.e. destroyed the blade) as SS requires contact with a fleshy material (not a wood and metal clamp).
Peter Henry I believe it works by the blade having a very small electrical current passed through it, it detects changes in this current and depending on that change takes action to stop the blade. I guess it would depend on whether the clamp metal was being touched during the cutting, which looking at the video looks possible.
Matthias Wandel A saw stop will be triggered by the smallest piece of metal including any part of a tape measure and backed insulation. Supposedly wet enough wood will also trigger the mechanism.
Peter Henry At work the saw stop has been triggered 5 times and only the last time was from someone's finger. You can easily test if the material that you are going to cut will set it off. With the saw OFF just touch the material to the blade, if the RED light flashes then you need to "lock it out" or better yet use another saw.
Very well done. I've been trying to think through a jig that would allow me to cut a dodecahedron out of solid wood for a while. It seems like a very difficult problem to me, maybe you have some insight. A small side-note: I think the term "geodesic" refers to something constructed using "geodesics" or arcs of great circles of a sphere. A polyhedron is not of geodesic nature because the vertices are "straight" line segments and not arcs of a circle.
Matthias Wandel I don't really understand how the idea of geodesics is incorporated into Buckminster Fuller's designs. Why aren't they just called regular polyhedra?
+Matthias Wandel so I just got the idea of dividing up each side of a regular polyhedron and then projecting it onto the sphere. It makes sense that this wouldn't yield a regular polyhedron.
If you wanted to hide those screws in the lid. Drilled pockets in the lid and the base and glued in magnets, just be sure to orient the magnet poles for attraction.
Nice work. I think you could make something practical out of it if you turn it round on a lathe, cut the top clean off, dye the outside maybe bordeaux red or jaguar green and add a nice wooden base to it (like a ring). Varnish it and the grain should come out awesome. Could be a awesome cookie or sweets jar, IMHO....
Once I tried to make one of those "barn stars" out of wood. I understand geometry well enough to calculate all of my angles and bevels, but the compounding errors proved to be too much for me to pull it off. Nice job here.
I remember when scientific American published the article about buckminsterfullerenes. I tried to make the crystal structure from clay balls and old pen refills. It was tedious to say the least. Great video as usual.
Hi Matthias, I really enjoy your channel. I'm curious on how you arrived at your calculations for the bevel. I've been trying to derive calculations in this area on my own with minimal success. Is there a calculator you could point to that doesn't require a learning curve as steep as the problem itself? I'm also interested in oblique pyramidal shapes as well. (meaning the apex is not in the center of the base). Any advice appreciated!
Why not use small neodymium magnets as the "lid" catch? Not sure what you have in mind with it, but the use of strong magnets would keep the lid on fairly well while still leaving the outside looking normal.
Next you need to write numbers on each face and use it playing D+D.... Yeah, never mind that. I agree about your comments about the miters! I think I might go bonkers with all those miters.
This is neat stuff. I work with icosahedral viruses that look kinda like this. Interestingly, the leading theory is that they assemble in much the same way you assembled it (pentagonal bits first).
The sawstop wouldn't of went off unless you were holding that metal collar of the clamp. I've cut through a nail before and it didn't go off. Thintz did an video a while back that showed this..
Matthias, sir I've been truing to figure out how to make a geodesic dome for so many years. I'm terrible at math, but I've been a welder for over 40 years. I can't figure out how I've been successful as a welder with poor math skills either, but that's another conversation. cam you share with me how you figured the formulas for different sided domes. I've wanted to build a Geodesic shaped Meat Smoker for many many years. if I can make a template, I think I can pull it off. I need several sizes, so it would be great to understand the formula.
If you had wanted to clamp those glue joints, a good way would be to get a sheet of 6 mil clear polyethylene sheet, put the object on it and wrap the plastic around, bunching it up all together at one face so it's in a sort of pouch, and suck the air out with a shop vac. You'd have a lot of pressure, even from all sides. As you pull the tube out, twist it tight many times and tie off with a plastic zip tie. Maintaining a seal would be the trickiest part - maybe clamp the plastic in a vise really tight. Or just leave it on a vacuum pump until the glue dries.
I recently have been looking at some videos of Da Vinci bridge, and Da Vinci Dome structures erected out of small logs, or sticks, or small lumber. Very interesting concepts, however the edges protrude out making it nearly impossible to cover with any kind of plywood, or paneling, or any kind of wrap. I am really interested in seeing what you could some up with to make these structures functional in the real world by use of fasteners like screws or nails with glue, and maybe wedges cut to fill the gaps at the ends of the boards which meet and cover other boards. There are videos of a guy using the Da Vinci bridge frame work to build a hot house/storage unit, and a cabin. I think you could do MUCH better than he did.
Its already been done for a long, long time. That's not to say it's some simple thing to do though. It's master carpenter type stuff, but the geometry of regular polyhedra is what is applied to n-sided roof framing. Essentially, the edges of a given polyhedron are exact stand-ins for the hip rafters of a roof whereby the roof sides correlate to the faces of the poly which share a vertex..
Thanks for the video. You've got my creativity wheels turning. I do have a question. Approx. how long is the base of your triangle? (the 8.95° side) I know your drawing says 1.176 for the base, but the triangles look too big for that to be inches and too small for it to be decimeters. Was it just a ratio of some other measurement?
Side length for equilateral triangle is arbitrary. Go ahead and choose whatever size you'd like - the geometry will scale while preserving its angles as they are..

This is awesome. Replace some triangles with semi transparent ones and put a light bulb in it.
This is a great idea... even if you stick with all wood you could cut slits or holes or simply leave the bottom section out.

Jay Bates was gonna call him on it too lol
I'd be a liar if I said I didn't gasp in shock when I saw it!
Matthias Wandel I actually laughed out loud at that disclaimer.
Mark Lindsay as did I! Plussed for that alone.
I can just imagine David Attenborough's voice at the end: "And here we have the rare footage of a native Matthias on a freshly laid egg..."
That would make a great bird house !
I like this idea. May have to steal it!
syd ascott It would, but with all the work it takes to build one, you should charge the birds rent.
man I needed this video like a month ago! I built a 1080 piece chair out of trapezoids fashioned to form equilateral triangles but I couldn't get the miters right to do my original design, props to you :D
The first sentence of this video tells you all you need to know about this guy. A TRUE genius.
With the amount of tolerance stackup involved with a process like this it's impressive that you only had a few small gaps.
That was a nice surprise! I will instantly have to fetch my own old paper-polyhedrons. I made a icosahedron from wood almost 30 years ago, but that didn't turn out as well as your dodecahedron-based geodesic, because I had a very cheap table saw.

That's some fine looking geometry; oddly satisfying watching it all come together.
I knew that there was a reason why I failed math at school. It's just so darned complicated. The table saw king strikes again! Well done Matthias.
This would be the start of an awesome series of lamps. Now I just need to figure out a jig to drill out most of the material from the center each triangle.thank you sir for keeping me busy for the next week.
You don't need to drill the centers out, silly - just make a skeleton frame using a length of wood for each edge..

I am fascinated by these types of work. Well done..
You are a huge nerd. I wish I had your talent. Well done.
Put a bunch of numbers on it to make it a D60
With all the cuts it came out great. Just a little error can really add up. now you have a fancy cookie jar.

Joshua Luther Easy method: Download Sketchup (free and Matthias uses it). Draw your plan. Use the protractor tool to measure the angles.
Joshua Luther A 4 sided pyramid would need 45 degree bevels on the sides. No need for sketchup for that.
@@Importenator you think so? Ok, how about the miter angle?..
Wow ... that must have taken forever to put that together.
Inspirational video as usual. Small point: I believe that SAW STOP would not have stopped (i.e. destroyed the blade) as SS requires contact with a fleshy material (not a wood and metal clamp).

Peter Henry A sawstop will trigger off metal, if it's big enough or touched.
Matthias Wandel A saw stop will be triggered by the smallest piece of metal including any part of a tape measure and backed insulation. Supposedly wet enough wood will also trigger the mechanism.

Is that normal masking tape? It seems to hold really, really well; way better than any masking tape I have ever used.
Kevin Medici Ordinary masking tape, but it didn't hold that well.
wow that is too cool. That must take a lot of patience to make all those pieces without knowing if it will fit perfectly
Great project Matthias! Thanks so much for sharing with us!!! W
If you wanted to hide those screws in the lid.
Drilled pockets in the lid and the base and glued in magnets, just be sure to orient the magnet poles for attraction.
*Very good job Matthias!!!*
Very cool! Looks like my summer project list just got bigger!
EL CHAPPY TAN If I attempted this, it would be all my summer project list would consist of!
TOTALLY AMAZED BY YOUR BRILLIANCE, HOWEVER WHY DID YOU NOT PUT THE HANDLE OF YOUR CLAMP AWAY FROM THE CUTTING BLADE?
if I put it on the other way, I'd have to reach near the spinning blade while clamping
Bravo, Matthias! Can you explain how you figured out the angle for the bevel cuts?
Cool and all. My only question is why build one? Is it a model or just for fun or something else?
Awesome job, Matthias
I love your weird testing methods... lets jump on it! Or stand on it! Brilliant!
Nice work. I think you could make something practical out of it if you turn it round on a lathe, cut the top clean off, dye the outside maybe bordeaux red or jaguar green and add a nice wooden base to it (like a ring). Varnish it and the grain should come out awesome.

(meaning the apex is not in the center of the base). Any advice appreciated!
mike trombly I was lazy this time and just measured it off the CAD model.
Knowing all the dimensions, would it be possible to put rods through the axes of a sphere and sand away the faces ?
Why not use small neodymium magnets as the "lid" catch? Not sure what you have in mind with it, but the use of strong magnets would keep the lid on fairly well while still leaving the outside looking normal.
Recalling my one attempt at compound cuts for fitting molding corners I am sitting here with my jaw on the floor in awe.
always been fascinated by euclidean solids...bucky-spheres are just an extension of those.....may have to make a set of them now....
Great idea and execution of that idea!
Thank you for your video, you are not selfish like others i have seen, the last cuts should be able to get them on miter saw, Correct.??
I'm gonna start wood working now because of this. I could build my own furniture!
Next you need to write numbers on each face and use it playing D+D....
Yeah, never mind that.
I agree about your comments about the miters! I think I might go bonkers with all those miters.
This is neat stuff. I work with icosahedral viruses that look kinda like this. Interestingly, the leading theory is that they assemble in much the same way you assembled it (pentagonal bits first).
+Mike Strauss an icosahedron only has 20 faces though. This thing has 60 making it a hexecontahedron
Very interesting. That would be interesting to make on from various types of wood and then turned round on a lathe

Fester Blats no
With so many repetitive cuts, it's easy to let your guard down. Glad you didn't cut into a finger!
That's crazzzzzzy! Cool but crazy, nice work.
Just rewatched this one, and still love the way you troll the trolls. Unsafe pocket hole joinery.
damn i need to stop watching wood shop type videos i get too jealous. i want all those tools and blades and that table saw is soo awesome
Buckminster Fuller was an amazing guy. And an excellent woodworker, I suspect.
Mr. Matthias Wandel Very Smart.
I salute with you Mr. Wandel.
How long from start to finish did it take you to make this? I love how I can watch it be done in all of 8 minutes. Keep up the good work!!
With all those repetitive cuts, the first thing I thought about was safety. People can often nick their hands on the blade with repetitive cuts.

You'd have a lot of pressure, even from all sides. As you pull the tube out, twist it tight many times and tie off with a plastic zip tie. Maintaining a seal would be the trickiest part - maybe clamp the plastic in a vise really tight. Or just leave it on a vacuum pump until the glue dries.
I recently have been looking at some videos of Da Vinci bridge, and Da Vinci Dome structures erected out of small logs, or sticks, or small lumber. Very interesting concepts, however the edges protrude out making it nearly impossible to cover with any kind of plywood, or paneling, or any kind of wrap. I am really interested in seeing what you could some up with to make these structures functional in the real world by use of fasteners like screws or nails with glue, and maybe wedges cut to fill the gaps at the ends of the boards which meet and cover other boards. There are videos of a guy using the Da Vinci bridge frame work to build a hot house/storage unit, and a cabin. I think you could do MUCH better than he did.
Its already been done for a long, long time. That's not to say it's some simple thing to do though.
It's master carpenter type stuff, but the geometry of regular polyhedra is what is applied to n-sided roof framing. Essentially, the edges of a given polyhedron are exact stand-ins for the hip rafters of a roof whereby the roof sides correlate to the faces of the poly which share a vertex..
I don't know what purpose this could serve... but it's really cool anyway!
This project is like watching the cliff divers in Mexico. Fascinating but I would never, ever try it myself.
Pretty cool! Now you need to make a tape dispenser! lol
Now we know where Fred Flintstone got his bowling ball.
This will be a great project for my grandson and me. Maybe a geodesic dome model...
Thanks for the video. You've got my creativity wheels turning. I do have a question. Approx. how long is the base of your triangle? (the 8.95° side) I know your drawing says 1.176 for the base, but the triangles look too big for that to be inches and too small for it to be decimeters. Was it just a ratio of some other measurement?
Side length for equilateral triangle is arbitrary. Go ahead and choose whatever size you'd like - the geometry will scale while preserving its angles as they are..
Awesome Mr. Wandel, tnx for sharing!!!
I like the stress test on an object which shouldn't really be under any load.
Well done. I couldn't do that. Really impressive
I have an overwhelming urge to kick it, but know it would just break my foot. Neat project
