I double-checked the flange angles of the tip rib to unsure it matched the taper of the spars, and then I radiused the front corners of the nose and tip ribs to remove the sharp edges and help them fit easily into the vertical stabilizer skin. With the final adjustments to the flanges complete, the entire vertical stabilizer skeleton was cleco'd together for the first time. I then cleco'd the skin into place to prepare for final drilling. It was very exciting to see an assembled part that is an identifiable piece of an airplane!
