The gussets that brace the corner between the rear elevator spars and the inboard ribs need to be final drilled. The area to drill, especially through the rear spar, is very narrow; so I used a 12” #30 drill bit to final drill those holes. The elevator mockup is then completed by clecoing the tip rib assemblies to the elevators. I had to look ahead to the end of the elevator plans to see that the tip rib skins lie beneath the elevator skins (sheet 09-22). All the #30 holes common to the elevator spars and shear clips get final drilled once the tip rib assemblies are in place. The final stask in this step is to trim the trailing edge wedges even with the edges of the elevator skins and to reduce the outboard thickness of the trailing edge wedges to match the thickness and contours of the fiberglass elevator tips.
