Aligned and drilled holes in replacement hinge. Deburred and riveted with CPP-42 rivets. Middle two rivets pressed on tail post reenforcement, distorting the lay of the hinge. Alignments with rudder looked good during trial fittings with Clecos. Bolted the tailpiece in place, torquing to 5.5 Nm using 3 Nm for the bolt/nut and 2.5 Nm to overcome the nylock friction. .After final rivet and bolting of tail post, Hinge pin wouldnt go past half way down the hinge. Used a trick introduced in Jeff Schultzs FWF seminar to open the hinge pin hole slightly. Using a piece of hinge pin, the end was flattened slightly with a hammer on a vise anvil. Ran pin through hinge to the top and chucked the pin into a drill. While turning the pin, pulled it up through the hinge, opening the holes slightly. The opened holes allowed the original hinge pin the fit through the knuckles.
