This continues to faccinate me. So the supports are designed to be left in while you thread the pieces and then removed afterwards?

Yes, first do an equilateral on the top and bottom, then join the ends (as in the photo) with 3 more.

I wish I could tell you what the best line and knot system is. I've used surgeons knots in low stretch polyester cord, as they allowed me to cinch it up nicely, but it was a huge pain in other ways, often requiring me to use forceps. I also tried heavy monofilament line, and it was a pain to work with. I've done a lot of physical modelling of tensegrities and finding a good tendon system is always a pain. I keep trying different systems, but none yet have really satisfied. The tapered plug system I'm using in my hanging planter is a candidate for scaling them up.

I use a woodturning pencil tool to remove supports, If you look at the supports closely you will see it's a very thin join between them and the tubes.
