I just finished my DIY bridge hammock and set it up for it's maiden voyage. Unfortunately, my foot end spreader bar broke on the first try. My spreader bar was an Easton aluminum tent pole tube, .433 diameter, single piece 26" long. The sides of the triangle were set at 18". It folded and broke exactly in the middle. I weight 180 lbs. The ridgeline was at 9'4" and the front spreader bar is a (2) piece .625 that is 36" long with sides set at 28".
I don't remember high school trig, so maybe some of you mathites can figure out where I went wrong.
Anyhow, I am moving up to .625 diameter easton tubing, setting the sides longer (I am using dynaglide whoopies for the side lengths so adjustment will be a cinch) and using (2) 13" poles with a pole insert in them.
