Had $30 and an evening to play, so I decided that with so many recreational type hammocks around, I'd build a stand so I could hang closer to the house, on the north side where the shade is for much of the day.
* (4) 2x3x8
* (2) cast/galvanized solid bolt-through hooks
* (2) captive/collared style hooks (no place to get carabiners locally, and these are pretty strong)
* (crapload) 7/64" amsteel blue
* few washers that I already had in the garage
* piece of old yellow rope, not structural, not even used until I take the hammock down
* 2ft of 3/8" all-thread rod that I had in the garage, cut into (4) 6" pieces
I also tried using the stake boom method out in the yard, but couldn't get it to hold to my satisfaction (yet), so I called myself defeated and continued on the porch.
I made a pair of continuous loops, 4ft each of amsteel and used the joist under my deck to secure to: feed the rope down under, hook it with a coat hanger and back up, then pass it back through and its a fairly solid hook point, this is also where the captive-nut carabiner replacement comes in:
The 2x3s got measured, marked, and drilled at what I hoped would be a reasonable height. Turned out a bit too high, but it works great.
The bottoms of all 2x3s got drilled in about 3-4", and each one got a piece of all-thread rod hammered into it to keep the feet in place. Here I show it being used in a wide gap between my decking boards. There isn't much stress on this point, most of it gets referred through the amsteel to the continuous loop/decking joist.
Make two whoopie slings (a bit differently sized than normal) and slip the fixed-eye end over the top of the collapsed end where your eye-hook is bolted through:
The finished product:
The yellow rope is tied between the ends, the ends are leaned slightly "out" from the center, based on the tension of the amsteel down to the joists, and they get pulled together when you lay in the hammock, adding more tension. I plan to take the hammock down before dew sets on it, and the yellow rope just puts a false load in so the uprights don't get pulled down to the ground.
Not exactly high tech, and really not even very elegant, but it sure is comfy.
