I'm fairly new to hammocking DIY, so excuse me if this has already been tried, but I couldn't find it when I searched so here it goes.
Thru-Hiker has the new Dyneema X Gridstop fabric available. It is stated that each spectra thread can hold up to 150 lbs. Since these spectra threads are placed every 1/4 inch that should mean that a one inch strip of this fabric should be able to hold 4 x 150 = 600 lb. So if you stitched 3 one inch strips together (3 x 600 lb) you should be able to hold 1800 lb.
The fabric comes in 60 inch width and is sold by the yard. It weighs 4 oz/yd2. Doing the math- that comes out to just over 0.5 oz for a one inch by 60 inch 3 ply strip. Sew two of these together and you have roughly a 10 foot by 1 inch strap that can hold 1800 lb.
It cost about $20 a yard, but you could get 3 pairs of 10 foot straps out of that yard, so your cost would be under $7 per hammock.
So, help me here. What am I missing? Has this already been tried and rejected? Is this just crazy and I am going to end up on my butt in the dirt when I try it?
I just got a yard of the fabric from Thru-Hiker today so I welcome your input.
