Topic tags/keywords: scoccer ball plans drawings dome sketch up

Ok guys this one goes out to those who have made woden scoccer balls or you guys that are real good at sketch up. First the background info – Back in 1972 Buckminster Fuller designed the Hexi-Pent dome. A simple to build and assemble dome system. Back then they offered plans of which I could not afford back then and today I cannot find them anywhere. So this project keeps surfacing in my brain from time to time and it again surfaced today. In the receint past I realized that a scoccer ball was in fact, A Hexi-Pent. Thus this question here.

For those of you who have made the wooden scoccer balls what is the angle that you cut each of the blocks to to make the angled joint that makes the arch of the sphere? Are all the angles that make the arch the same (I would think that they are)? From small to large as long as you have the same amount of pieces the angles remain the same whether it’s a 12” scoccer ball or a 20’ dome.

Now you guys that are sketch up wizards I’m sure you can give me the same info.
I really would like to try building this type of dome but I need some accutate angles. I have made paper dome, straw dome and stick dome models but my brain just will not give me the correct answer. For some reason I have never been able to get my brain to think this way. Even with the meger drawings in the 1972 Popular Science about the Hexi-Pent and owning and reading both Dome Book 1 & 2 I just cannot get it right. Anybody able to help me out here?
