Well, I tore into it tonight. Removed the bark and the sap wood on one end and tried chasing a ring on the end I showed in the pic. It didn't go very well and I think they are way too close for a first try at a self bow. Spent three hours on that dang thing and made it about 8 inches with three ring violations already. Backing will be needed.
So if I wanted to turn this thing into a BBO, can I simply rip the back on a bandsaw or run it over a jointer to get a flat surface to glue the bamboo to?
In those three hours I spent trying to chase a ring, I developed a whole new respect for you selfbow guys
I honestly don't know if I have the patience for this type of bow and I already had thoughts of running that sucker through my bandsaw to make laminations for a glass bow.
