manchuarchery.org has the build process of one
Also hornbowyers and ATARN on facebook, though it's mostly tatar, turkish and magyar bows. yokhua has made several though. Also someone made a ming style and a mongol style bow. Also Alex Wittenaar made several Mongol style horn bows, at least one with a black locust core.
I think the good thing about bamboo is that it's more accessible and maybe don't have to worry about knots or grain violations like with wood??
