Thanks for the thorough how to Ray, couple of Q’s if I may to either u or Dana?
Dana leaves a small step at the back of the thread underbody, near the base of the tail. This helps the first wrap of hackle fiber to sit properly on the back of the fly. A small detail, which comes with experience.
Small step are u referring to a thread bump/ramp?
Also wanted to ask about the quill, you say trim the fibers either side short, when you flatten the quill with the pliers are you positioning the quill flat with stubs pointing out either side of the rachis or trying to flatten the quill with the stubs contacting top and bottom of the pliers?
Last question is how do you wrap the quill, flattened quill with Stubbs left and right of the rachis slightly overlapping? Also do u try to mount the quill so that the curvature of the rachis is positioned so that it conforms to the direction you are wrapping? Flattening the quill may negate this a bit, I grade all my quills and biots so I know which way they will naturally wrap. Makes for a neater and more durable body. Love to hear your thoughts...
