Many thanks to everyone for the positive comments.
I used solid 3D modeling to get a rough idea of what it should look like.
Then I hung the project at several stages during construction and verified some dimensions, and adjusted as necessary.
All connections were made with 3M 9460 adhesive and primer.
1. Lawson used the same weight cuben as me.
2. Lawson looks to be a bigger guy than me, and he seemed happy enough with his own testing to nearly bring them to market.
3. The guy who was testing the prototype that broke weighed 260# and it did not fail on the first hang.
4. I weigh 150#
I certainly am not selling this product. I simply hope that my testing proves that it is strong enough for myself.
Another hiker has used a lighter weight cuben hammock on many trips and it has not failed for years.
Hoping this thing is usable near 30 degrees.
I'll try it in the backyard this Friday at about 38 degrees.
The enlightened equipment quilts were certain good fuel for this fire!
Currently mine has only one small opening hemmed with netting.
I have a much better plan, but had to seal this thing up and try it after several days of working on it.
I will operate on it some more over the next few weeks.
