different cross section shape for different skin types?

Post by brillythekid »

Hi Everyone,

Building a folder, for the most part according to Tom Yost (Yoswerks) instructions. On the site PVC is recommended for the skin; and the cross-sections/stations are somewhat concaved (1/2"-3/4"). (From the Yostwerks site: "Concave Cutouts - To accommodate the concave nature of the skin [PVC] while in the water").

I have nylon material available to me, so my question is this: I understand nylon expands\loosens in water, so would it make sense to leave the cross-sections straight without concaving them or concaving them less than with a PVC skin, or are the concaved lines in the cross sections advisable also with a nylon skin?
