Today samples of canvas came and so did the ballistic nylon. I was not impressed with the canvas 10oz samples but it gave me some materials to plan the front folds with the steel overhang and screw locations. Enough for 2 layers of 12 oz cotton canvas is on it's way, thus I will have 2 inner layers canvas + one outer layer ballistic nylon + insulation. Only the 18oz seemed worthy of using without the outer BN.
Tomorrow I'll get the "duck bill" 14 ga metal strip 2x2 with 30* bend and a 3/4" strip to sandwich all the material. Was planning rivets but stainless small bolts are sounding better. My fold will result in doubled BN + 2 layers of canvas folded over....so about 1/4" thick of canvas and nylon to sandwich and hold on the bottom of the duck bill . I'm leaving enough nylon to be doubled back (10") under the outer layer for reinforcement.
This thing should stretch very tight and have plenty of padding on the leading edge. I will round the steel edge and may put other protection on the edge that (4) layers wrap around.
I may be able to similarly anchor the back with steel strips to pull against, to make it tight.
