I was lucky enough to join the Jacks from Jacks 'R' Better at Trail Days 2012 and saw first-hand the pipe stand that they used for their demonstrations. The Jack's used 2 in. pipe that was virtually indestructible. I liked it so much that I made my own for my hammock demonstrations. I made mine from 1 in. pipe and it has been working flawlessly. I love it!
This stand packs down and travels much better than my Vario stand and it works perfectly with a tarp.
The Jacks' stand is based on the Speer design from 2004. This is nothing new: there are lots of variants on the forums, but I thought I'd draw up the basic instructions from the Jacks for the benefit of the forum. Take it and run with it!
I wrote up a quick blog post on my website for non-forum traffic.
