bamboo bow and cores

i started my first hornbows years ago. for many reasons,most bows broke and some were too strong to draw. i have to say it is hard to glue horn to bamboo.i learn sth new each time i make a bow,and it is fun to learn.
i happened to find some bamboo pieces under the sofa,and some on my roof. i must have stored them years ago. an idea came to me --why not try some bamboo bows. :)
in Ming dynasty,chinese bowyers would smoke the bamboo for at least 6 months.i smoked the pieces for a month when my father was making bacon.then i glue the peeces together.
