All the joints are given a going over with Titebond III, including the capstrips.
Balsa is added to shape the lower section of the rudder to fair to the aft fuselage.

I did not include this detail on the plans because it seems like everyone has their own favorite way of hingeing control surfaces.
Tools used to shape the leading edge of the elevator. The shaping should be done so that there is a constant radius about the center of the carbon fiber center joiner.
After aligning the elevator with the stabilizer, at the location of the outer hinges a T-pin was pushed through at the same height as the carbon fiber center joiners. The elevator was
separated from the stabilizer and a guide hole was drilled through both components from the front of the elevator and the back of the stabilizer to get exact alignment.
