Making a small 60-sided geodesic dome out of solid pieces of wood. Lots of miters! woodgears.ca/geodesic/ A 60-sided geodesic is derived by taking a 12-sided dodecahedron and turning each pentagon into a 5-sided pyramid.
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.
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.
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!
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 :)
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 RU-vid channel. I am now inspired to try to build my own.
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
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 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
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
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.
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.
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.
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.
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.
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.
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
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
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!
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!
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....
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.
Ive always wanted to make a 3D pumpkin mask for halloween. I might do this with cardboard so its lighter and then paper mache and paint it to finish it off. Thanks for the measurements.
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).
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....
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.
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.
