(...) We looked at 22.5 deg joints but it's not so much the angle (well, 22.5 vs 90 yes, but...) as the sudden increase in outer diameter due to the joint. Once you build some flexibility for the increase in diamater due to the fitting, most of the (...) (22 years ago, 30-Dec-02, to lugnet.org.ca.rtltoronto, lugnet.space)

This is so cool! I really look forward to see how this is developed. I imagine it will be quite a trick to get this across the joints. Have you thought about a less extreme joint? 30 deg maybe?

It's really quite fun--part of it is because it's in 3D vs the usual 2D building we do (ie, wheeled/tracked floor based vehicle) and at that, you have to work at any angle (because the pipe is 1D, but you can approach the joint at 360 (...)
