I just laid up a set of 80# recurve limbs and got them mounted on the riser. i'm doing some different lam configurations on 3 different sets. One set will be 115 # and i'm trying a new recipe to get better longevity . My last set this heavy had compression fractures in the maple on the belly side, so i have a different plan this time. The 3rd set for this riser will only be 65- 70# and I could just use maple on those with .040 glass.
I'm experimenting with this Fossilized woven bamboo on the belly side. So far my tests are showing higher compression strength than maple. The epoxy infused bamboo is seriously hard stuff, but surprisingly flexible. I was afraid it might be to brittle at first, but its held up well on heavy bows so far.
