(...) Wow! I for one can hardly wait to see the video of this. And I would love to see more explanation and construction details too! cheers, Alexander (17 years ago, 10-Dec-07, to lugnet.technic)

Thanks -- making a hexagon out of equilateral triangles occurred to me after submitting my post, but I really had no idea what was going on with the funny angle, so this has been very educational. As always, this is one of the most helpful and (...) (17 years ago, 10-Dec-07, to lugnet.technic)

(...) Try approaching it in steps. Can you make an equilateral triangle out of Technic beams? Don't worry about making the angles rigid, just make a structure with three equal-length sides, connected near the corners (connected with something that (...) (17 years ago, 10-Dec-07, to lugnet.technic)

(...) It would appear that they're approximately 126.8698976 degrees. That's from approximating some angles and noticing that what I think they were trying to do was to create the geometry such that a 3-4-5 right triangle was possible. DaveE (17 years ago, 10-Dec-07, to lugnet.technic, FTX)

Your best bet would be the #4 angle connector, its a 135 degree angle. (17 years ago, 10-Dec-07, to lugnet.technic)

I'm trying to make a largish (20 cm across or so) octagon or hexagon out of technic parts. I thought this would be easy, because I believed that the bent technic beams (e.g. (URL) 32348>) had a 135-degree angle, or at least some angle that would (...)
