I've been researching DIY stands as my yard is treeless and I had been planning to do TrailH4x's Portable Hammock Stand as designed, but came across some other ideas today that made me wonder if the upright braces could be eliminated. It stems from this design:
and this post by WonderMonkey:
What if you extended the base of the PHS 2' past the upright, keeping the uprights in the same place. You could then attach some Amsteel whoopies to the ends of the base up to the uprights through an eye bolt like WonderMonkey's design shows? What kind of forces would we be looking at on the whoopies? I'm going to try and go through the math exercise to see what the tension would be, but someone whose statics skills aren't 10 years old might get it faster.
You'd need some sort of light line between the uprights just to keep them from falling down until the hammock is loaded, but the line would not be under tension in use.
