I made a long bow last year with the directions from an old fox fire book. i stuck a strong piece of bamboo in a home made mold and let it dry there for bout a month. i got a hold of some jug fishing string and drilled a hole through each end till it was pretty taught. turns out 7 months later i'm still shootin with it and it's got a 45 lb draw weight. Bamboo is really quiet too!
