1. Sanded the foam filler blocks in the ends of the caps. Sanded the filler at the interior skin seam on the elevators.
2. Used a set of smooth-jaw pliers to add a slight pre-bend to the outboard ends of the elevators skins. This will help the caps fit better.
3. Fitted the caps to the elevators and clecoed them in place to check their fit.
4. Sanded the trim tab filler and several other areas of filler on the elevators.
5. After observing the way the curved elevator leading edges met in several spots, I decided to remedy them by adding four rivets -- two on each elevator. This improved the way the skins joined immensely.
6. Filed the openings in the L elevator skin and access cover where the elevator trim tab actuator arm passes through, to give it a bit more clearance.
