Lot of folks over here practice what we call "Catch and Release." It's the thrill of the hunt. Actually, the machining concept for bamboo rods has been around for a long, long time. The old production rod makers had a number of different machines for making the tapered strips. In fact, my design is kinda borrowed from the designs of the machines used by the Payne and Leonard companies. They used saw bevelers to cut their strips. The two big differences - the cutting heads remained stationary in the Z axis, and the strip was pulled through the machine. The taper was implemented through that use of what was called a taper bar that was pulled through the machine at the same time as the strip. A bearing rider with a push rod was utilized to move the cutting head up and down so that the saw's imaginary "point" was the bottom, or pointy part of the taper cut into the stick. Other older machines were like the more common bamboo mill, with 60 degree cutters running the length of the strip. In this case the "V" was inverted, with the apex at the top, and they cut the strips from the pith side of the bamboo. My machine cuts with the enamel side up and the pith side down. My saw beveler machine is also a single pass machine, while the millers were typically multi-pass machines.
