When we heard that the latest challenge was chopstick based a friend said to me that I should make "one of those mad pencil thingies but with chopsticks rather than pencils".  I finally managed to get sense out of him and he directed me to this website and the amazing work of George Hart:
http://www.georgehart.com/sculpture/pencils.html

I sourced some super cheap chopsticks from ebay and set about making my own slight variation.  I knew I could not use exactly the same design as the chopsticks where not hexagonal cross section like pencils and they tapered.  So rather than the 72 pencils of George Harts original creation - I went for 76 chopsticks in a solid three to the edge hexagon rather than empty 4 to the edge

Step 1: Craft temporary rigs I

First you need to get the spacing of the chopsticks straight - in your head and then on paper.  Each set of chopsticks fits through each other set at a 60 degree angle.  This part does not need to be absolutely millimetre perfect - after drawing lines at 30 degrees apart on a piece of Westfoam 5mm foam board,
1. To avoid ripping paper make a tiny cross cut in the board (much smaller than cross section of the stick) at the point where the tow lines meet.
2. Supporting the board push one chopstick through 
3. Lie a chopstick flat on the board and ensure it is point at around 60 degress
4. Draw around a second upright  end of chopstick
5. Repeat with another to get a good idea of the separation needed.
this give me an idea for a chopstick holder...hmm
Here are alternative instructions for building the same object<br>http://alejandroerickson.com/joomla/personal-projects/90-how-to-make-hexastix-detailed-photo-instructions<br>(sorry, I haven't make it an instructable yet)
I love it and all the other post too! So many crafts to explore
Nice. Her's a template to print to make your holders. Sized for pencils. You may need to enlarge a little for chopsticks.
Very nice - you would have to use sharpened pencils rather than the flat ended that most model makers use :-) But your template would make it much easier - thanks
Here's how I did it:<br> Cut out a few of the templates. tape them to cardboard. I didn't have foamcore. Then use a sharpened pencil to poke all the holes. Then assemble with unsharpened pencils.<br><br>-Caleb<br>
Yeah - I should have thought of that! <br><br>Foamboard is great stuff - I bought some because it was in a sale (sucker for a bargain) and I have used it regularly for modelling ever since. I tend to use it more for support and structure - rather than a primary medium, but it is so easy to cut and craft. I tend to reuse it because of this - ie I sliced up the above rigs and reglued them for support of a clay model - it means that I am still on the first box that I ever bought.<br><br>Next project is with cocktail sticks - a variation on the lovely model that Alejandro posted below
That is awesome!!!!!!!!
Hello Astropoke - it is fun isn't it! It's gonna be really difficult to keep dusted though so I think an explosive deconstruction may be called for sooner rather than later
re band it and throw it in the dishwasher, let it dry and then re-acetate
Madrigone - elastic bands and into the dishwasher? Might work - those things get quite hot tho - might open up to a disassembled mess
Use hair bands - the cloth covered kind - they are usually tougher.<br>If you're going to 'splode it anyhow, couldn't hurt to give it a shot...
If you're going for explosive deconstruction, videotape it and post it here!
I might have to rig it to make sure it is impressive enough! I will try freakyqwerty's suggestion of canned air for a while - till I get bored.
Noo! Give it to me! =D
Canned air... Unless of course you are looking for an excuse for an &quot;explosive deconstuction&quot;... : )
Freaky - you got it - I am always looking for an excuse for explosive deconstruction! :-)
Simply amazing! And a very clear, concise instructable--not that I'm likely to try it, I'm not a particularly patient sort, but your work couldn't be easier to understand. Beautiful!
Thanks your kind comments Suayres. I don't think of myself as a patient sort - but I guess I must be. The satisfaction when hours/days/weeks of work come together in a beautiful object is really special
Tension/compression in action same principle used by Romans to quickly do formwork for stone arches best use recorded in the building of Caesars bridge accross a wide river in 14 days- nice work! Self Explanatary
Thanks Stephen - Bamboo is amazing stuff, I think/fear that the Romans would have been even more efficient at building if they had access to such a resource
Please, oh please record it if and when you drop this!!
Fun! Welcome to the infectious world of geometry. Here is another way to do those&nbsp;<br> <div class="media_embed"> <object height="300" width="400"><param name="movie" value="http://www.youtube.com/v/C7VaEZXwH8M?version=3&amp;hl=en_US&amp;rel=0&amp;hd=1"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed allowfullscreen="true" allowscriptaccess="always" height="300" src="http://www.youtube.com/v/C7VaEZXwH8M?version=3&hl=en_US&rel=0&hd=1" type="application/x-shockwave-flash" width="400"></embed></object></div> that I posted on Youtube, and here is a picture of myself with a slightly crazy one http://www.flickr.com/photos/alejandroerickson/6012575847/in/photostream.<br> <br>
Hello Alejandro - fraid I am already a long term addict, I just hadn't tried using pencils/chopsticks in that way before. Most of my stuff is paper and card - modular origami and cardboard geometric shapes.&nbsp; I think my favourite would be the five intersecting tetrahedrons<br> <br> But I am also doing a lot of experimenting on one sheet repeated folds like the two examples below.&nbsp; Great models btw - will have a detailed look at your video and photos on flickr, might try to find some nice variations on the theme.&nbsp; Cheers<br>
Oh, and a little white glue goes a long way, and is quite invisible.
Congrats for winning!!!
Thanks Astro. I am well chuffed!
