Hey guys! This look incredible! I want to build one!
I have a few questions from experienced builders for this project.
First, the light poles are elegant, but I am not as concerned about the carry weight for my purposes, and want a build list that I can fill out at any hardware store. How about 10' galvanized steel pipe for the poles? Very strong I imagine, but heavier. Would that impact the effectiveness of the structure?
Also at least for the first build I was considering using 1" ratchet straps for the tendons. At least while trying it out. I want to make sure I understand the type of forces at play here though, The 1" ratchet straps I have are rated at 900 pounds, which I think would be sufficient, as dejoha was talking about using 550 cord. Although with the levering and tension of a tensegrity structure I don't know what kind of strength I need for the tendons. I like the idea of ratchet straps because I can set them to the right length to start.. then tinker a bit if I have to without re-knotting.
I think once I get the dimensions right something pre-measured might do for the upper and lower triangles, then maybe only straps for the side tendons.
I notice they sell 1" steel pipe in 6' threaded lengths, with 2 inch threaded couplers, so having a segmented heavy pole would probably work out as well.
One key consideration in choosing the material for the tendons... stretch, which should be minimized. That's why we used Amsteel, which also eliminated worries about the load.
I used the 1.25 EMT conduit and never had any issue with bending of the poles, so I am sure the heavier conduit would have no problem.

Ok guys, I'm intrigued by this... We are going to be setting up a camp for 24hr+ for a ragnar trail event in November. I'd love to have a way to hang at least 3 hammocks, if not more for lounging.
How have they been holding up? Whats been the best pole so far? I saw the video of Mac's collapsing.
Just make the tensegrity stand such that the struts all intersect touching one another, and bind them together.
