I have try this before.
It work good indeed, just, I heat treat hickory into reflex after I pre-shape it, holds reflex better and make better bow, I think.
Last bow is flat limb bow, 62" long and 11/4" wide, no set. I think it is 46#@26", limb thickness only 1/4" thick from middle of limb.
Also, it is good idea to make bamboo thinner in working area, can be thicker at tips to make less hickory. Trapping I did do, but I think little more is harder when limb is thin like that.
