I have fabric on the way that I am going to use on my first attempt at making a Bridge hammock. I was sitting here this morning playing around with lVleph's Excel program (via blackbishop's directions for making a cat cuttarp) for making the cat cut curves.
I have decided that I am going to shoot for a finished hammock that will be 84" (~7') long and I will be using fabric that is about 60" wide. Using lVleph's program I have been fooling around with the sag inch/ft measurement which basically influences the depth of the cat cut.
At 1" sag/ft the deepest part of the cat cut is going to be 5 1/8" per side which means that the narrowest part of the hammock (the middle part) is going to be about 49-50". If you go with a 2" sag/ft the deepest part of the cat cut is 10 1/8" per side which means you the narrow part of the hammock will be somewhere around 40" and with a 3" sag/ft you are looking at about 30". etc etc
I'm sure the depth of the cat cut is definitely going to influence how easy it is to get in and out of the hammock because a lower sag in/ft is going to make higher sides of the hammock to climb over to get in. On the other hand I would not think you would want your sag in/ft to be to high because a really narrow middle section might make moving around or lying in the fetal position difficult. I'm thinking that the depth of the cat cut may also have some influence or how the hammock lays and hangs. Is the depth of the cat cut also going to influence the forces on the edges of the hammock?
Any thoughts?
