Thanks Allen. I have plenty of bamboo. Right now, I offer raw MOSO bamboo backing strips for bamboo backed bows. Like Allen mentioned, these can be ground down for lams. I am hoping to offer ground lams in the future, but for now, my prices on the raw are good enough that you might want to grind them yourself.
When I say Raw, I mean it has the natural outer surface of the bamboo as it grew. They are dry and ready to work. Pretty flat, from large diameter moso bamboo. They are 2" wide and 6' long. 8 foot lengths available but incur an oversized shipping charge.
