    Thank you very much!

    It only takes a few minutes to set it up, but with rings it will go a long way towards idiot proof... only one way will it work.

    I appreciate the kind words... it has been in the works for a while.

    Over a year ago, I tried to find someone at NCSU who could help me calcluate the loads on a tensegrity. No one responded. Turns out I did not need to calculate loads, but rather to share them.

    Did you ever build a bigger one? And how about a multi-hammock setup?

    Nope... we used the strut material in building a rabbit run.

    The important thing is that by making the X Tensegrity stand we solved the problem with the previous Tensegrity stand. Just lash the struts at the intersection, so that each provides support for the other.

    The X Tensegrity is simply a small 3 strut Tensegrity tipped over on it's side. If you build a large 3 or 4 stut Tensegrity stand, just orient it such that the struts cross right by each other. Essentially, that means making the base smaller... so you may need guys to keep it from tipping over. Anyway, with the struts touching at the crossing point, lash them there, and you are all set!

    MacEntyre, you leave me hanging! :-) Here I was about to shell out for almost 50' of pricey carbon fiber poles to try to build a 2.5lb TurtleCarbon stand that would pack to 21.5" long, when I stumble last night onto this, that promises to do the job with just 27', fewer splices, more elaborate cordage, and way cooler looks! And you built a rabbit run instead? Did Big Turtle send by their thugs to stifle this idea before it threatened their hegemony?

    When you tipped the stand up around the 10 minute mark, I wondered: couldn't the same structure hold 2-3 hammocks with some good staking?

I was hoping to avoid the iterative prototyping process using relatively inexpensive materials we've seen here, that are too heavy or bulky to pack all day, and leap straight to a proven optimal design in carbon, amsteel, Dutch bits, which I think could come to around 25" and under 3 lbs and accommodate 1-3, whether in a hotel, a bedroom, on a beach, or a mountaintop. I suspect the raw materials cost of carbon makes a commercial product un-viable in consideration of the liabilities involved, but there's no markup or liability for DIY...

    Sorry! I should get three 9' aluminum poles, fabricate three unions, and make the final Tensegrity Stand.

    The X Tensegrity Stand was made with 8' poles, and that is a bit short.

    The 9' poles would be cut, but not in half... probably 3' and 6' pieces from each.

    If the unions are strong, the 9' poles could be cut into (3) sections each 3' long, for better packing.

    Or you could cut one pole into (3) sections 3' long, and the other two poles 3' and 6'... pack all the 3 footers, and use the 6 footers for hiking poles.

    Yes.

    The X-Tensegrity Stand for one hammock is the same as the original, tipped over, with one short strut.
    You could tip over any symmetrical tensegrity stand and have the same thing.
    It's just that your hammock would be hanging over the end of a pole.
    Don't fall on it!
