A guy I used to work for built bamboo fly rods. You split and taper each individual lamination. The simplest one is made of two pieces tapered and laminated together. If anyone would like I can get some info from him on tapers and length. From what I've seen him build all you really have to have is a hand plane and to make your self a form to plane the tapers to. The 6 piece rod I'm no sure about.
