Thank you James....Yes, I have built several bamboo-backed bows...no boo bellies, yet. All have been either hickory or osage bellies. None draw anywhere near as cool as yours. My 48" bows stack at about 24" draw. I guess it's a design flaw I haven't figured out yet.
Anyway, your bow is a model and an inspiration, as in: "this can be done!" So, back to the drawing board with new hope! Any further secrets you're willing to part with would be more than welcome.
Thanks for sharing that great bow with us.
