    I made one of these! I didn't cut the notches for the rubber bands deep enough. when assembling, it really wants to curl up and undo everything. My current solution it to press one half over a glove and add about as much as you can, then start lifting and adding a few more pieces. at this point there will be a bit more than half and there is enough structure to make it curl down. remove from globe and continue assembling.
    I wrapped an LED strip around a section of pvc and inserted mid construction. hung with fishing line, makes an awesome pattern that looks like marble.

    You do some really amazing work. Some day I hope I can have a wood shop like that. I've always had a passion for wood working and have been a carpenter for several years but never done any real fine finish work like cabinets or furniture stuff like that. But I really enjoy your videos
    Thanks for sharing your passion so others can enjoy your great ideas.

    I made a kite string reel many years ago that I wanted to be heavy-duty because I like to fly my kites at very high altitude which means pulling in a lot of string.
    It had two dowels to wind and they were glued into 1/2" cabinet plywood.
    -----|--|
    |--|
    |--|---
    Well, I used it to wind in the kite and the whole thing completely crushed under the compression from all those winds of kite string.
    I was shocked that could even happen. Up until then it had never even occurred to me how much energy I was storing by winding the line in that way.
    I learned that the best way to do it was to pull in the kite by hand and wind the line without a high tensile load on it.
    Really cool project. I think I might make one. I'm thinking cherry for the hexes and walnut for the pents.
    Or maybe maple and walnut.

    Wow! What a very cool project! I'm new to fabricating and was wondering if you would suggest some books that may help me to learn how to use some of these tools properly and maybe some design reference you found inspiring. I'm studying sculpture and really got a kick out of this project! Thx!

    • @pocket83
      @pocket83  9 лет назад +1

      CHRIS polidoro When I did study design briefly, I was quickly drawn (sorry for the pun) towards the geometrical end of it all, so I might not be the best person to ask. However, I can easily recommend to you James H Earle's _Drafting Technology,_ which will no doubt become a useful companion to you. I always had a fondness for the artistic works of Escher, which could also provide you with hours of contemplation, with respect to your ongoing investigation of design. Good luck as you move forward, but expect change. When I was in high school, I was certain that I would become a sculptor, as well. I used to love it. Above all, keep studying; after having chiseled away at our misconceptions about the world for long enough, it's not be unusual to look back and regard that pursuit as our most productive sculpt.

  • @boomfiziks
    @boomfiziks 9 лет назад

    Sorry for the multiple posts. When you cut the slits that hold the rubberbands, how deep did you make them? Also, if were to do it again, what changes would you make in your jigs or procedures?

    • @pocket83
      @pocket83  9 лет назад +3

      The rubber-band slits are cut to around one half of the thickness of the piece (half of 0.5"). It is worth noting that I am using a thin-kerf blade, so that the slit is cut less than 1/8" wide. These slits are spaced such that 0.25” of material remain in between them, ideally.
      As for the “chamfer” question: These parts do have an angled cut added to their bottom edges, and this is shown in the first video. The cut is made at 20° with respect to the table-saw, and it comes up the side of the piece about 0.125” high. If I am not understanding/addressing your confusion correctly, you will have to further clarify.
      With respect to procedural changes, this is already a sound method. But if I were to do anything differently, I would make a chamfer sanding jig for the 20° inside edges, rather than sawing them back and forth on that makeshift sled. This would create a less damaging cut with less overall risk. Further, the jig would make the cut with respect to the edge being cut, rather than with respect to the overall polygon, which would eliminate chamfer size variations due do minor size discrepancies. If you would like a visual of this chamfering alternative, I discussed doing this with a disk sander in the Rubik's Snake puzzle video.
      I am glad to assist anyone who would want to construct one of my projects, so please let me know if I can be of any further help. Oh, you should know that I have posted two videos on this subject; one is a build, and the other is a solution. Also, I can provide you with any of the diagrams used in the videos (I first used a cut-out-and-taped paper version as a visual reference) should you need a “blueprint.” Out of curiosity, is there some physical principle or phenomenon that you had in mind, for which this could be used in demonstration? Good luck ;)

  • @jesslarche8129
    @jesslarche8129 9 лет назад

    a tip i thought of while watching is for anyone that is having trouble remembering to skip one pentagon while putting it together as you mentione was a star. the way i remember is that of putting a wheel on a car and skipping a lugnut. i would assume its for similar reasons to equalize the pressure across the surface instead of over tightening one area but i could be wrong

  • @boomfiziks
    @boomfiziks 9 лет назад

    That is just beautiful to look at. I've got to make one for my physics students! Do you think it would help to slightly chamfer the edges where the pieces come together?

  • @blackmephistopheles2273
    @blackmephistopheles2273 6 лет назад

    An easy way to visualize going from the regular icosahedron to the truncated one is:
    Mark every edge to be cut into thirds. Then color in the corners, down to the first mark - the uncolored parts then make hexagons!

      The original plans/ideas were quite different originally. I kind of worked on three projects at the same time: the build logistics, the rubber-band routing, and the solution's algorithm. A change in one would affect the others. I almost scrapped the idea once or twice.

    Only a few snowflakes have 6 fold radial symmetry or any symmetry at all. Most of them are irregular.

    • @pocket83
      @pocket83  9 лет назад +2

      ***** And there is no such thing as the perfect circle, either. We use mathematical models as conceptual tools for developing a furthered understanding. That being said, the rules that govern the formation of snowflakes describe 6-fold radial symmetry. I had attempted to photograph many snowflakes for this video, and damaged ones aside, they all had 6 petals (arms). They strive for an impossible goal. Inspiring, isn't it?

    • @SkyFoxTale
      @SkyFoxTale 9 лет назад

      pocket83 Interesting. Rarely any of the snowflakes I have seen have the 6 petals you speak of. While I don't draw inspiration from romanticized personification of them, I do find the results of the shape and electronegativity of water molecules quite beautiful. If you have read a maths paper on the formation of snowflakes I would be very happy if you sent it to me :)
      Thanks for the great video!

As for my romanticizing, pardon it, and I will just assume that you are an android who is learning to interpret irony and hyperbole. Consider: I make a claim that has been well-established for centuries, and I still receive comments from intelligent-sounding yet apparently ignorant challengers; see if you can connect the two parts to my "impossible goal" metaphor.

    I have a little question. Is it possible to know how much degrees is th e angle between the exagon and tne pentagon?
    I mean the visible gap outside the shape of icosaedron, 'cos inside all angles are closed.
    I ask it because it would be interesting to make the pieces with the correct angle to glue them tovether.
    I hope you u understand my poor english question...but you are smart and I am sure you bet the point;-)

    • @Nomen_Latinum
      @Nomen_Latinum 8 лет назад +1

      If you're still interested, we call the angle between two faces of a solid the dihedral angle. A quick lookup on Wikipedia tells us that the 5-6 dihedral angle for a truncated icosahedron is 142.62°, meaning the angle of this gap you're referring to is (180°-142.62°)/2 = 18.69°. Similarly, the angle of the gap between two hexagons is 20.91°. Hope that helps!

    Dark matter is solved when mankind realize that the galaxies we see are truncated versions of 4 dimensional geometry. When they reverse the truncation, they will see the restoration of the expected Newtonian physics thus eliminating dark matter. Invert all that and conveniently dark energy is solved. Like an inside out black hole. As you travel As you travel from the center the reverse truncation appears to accelerate the expansion of the universe thus accounting for the dark energy

      Ivan Solomon Nathan loves milk incredibly. That's pretty low for something handcrafted to such a degree of accuracy. You are implying it only takes him 3-4 hours to construct. I am not a carpenter, but I assume it would take that amount of time to only sand and finish all the pieces.
      I would guess around 6-8 hours start to finish of actual working hours. ($20/hr)(6 hr) + (cost of material)
      I would start the offer at around $120 USD and then see what can be agreed upon.

      pocket83 this hits the nail on the head. So many projects I've made, people have asked me if they could buy one. But unless it's something you're making to just pass time, rarely is it ever worth it. Example: I designed and created a business card holder that's unique and (vainly speaking) gorgeous. However, if you factor in the material cost (I used walnut) and the time I spent on it (not including design), at minimum wage ($12/hr here), I should be charging $120 for one. Can you think of a single person that would ever spend even close to that for a business card holder??

      If you see me being short with those "reasonable" commenters, who think that I ought to ignore everything, it's simply because I receive that same comment constantly. My _not_ ignoring comments drives a certain small but bizarrely fixated demographic simply mad. So, no. You ignore this.

      I just looked through a big portion of the comments for ones he responded to. I only see detailed / technical respones and replies of gratitude rather than rude ones. :\
