Step 3BB Shell, Heat Treating
I cut a short piece of bamboo to act as a sheath for the BB shell, and then used a rasp to increase the inner diameter until the bamboo fit over the BB shell.
Heat treat your bamboo first, as there is a little shrinkage that happens when you heat-treat. I learned this the hard way. When heat-treating, I found it easiest to have the flame be very small and be very patient. Heat treating strengthens the bamboo by caramelizing the sugars inside it, bonding the fibers closer together. It also looks nice.
