Found the midway point on the trim servo arm and cut the trim servo rod to 130 mm in order to install the rod from the trim tab hinge to the servo arm with the trim tab in the neutral position. Drilled out remaining holes in the elevator skeleton and the elevator horn assembly. Removed all clecoes, trimmed elevator parts and deburred all drilled holes . Total time = 11 hrs.


Deburring, Cleaning and Applying Anti-Corosion Protection

9/25/11 - Cleaned all surfaces and coated with anti-corrosion protection. Re-assembled elevator skeleton and riveted together. Re-attached top and rear skins to skeleton with clecoes.

A Thing of Beauty!

Elevator Complete

10/9/11 - Filed down the horizontal stabilizer horn so the elevator could rotate freely without hitting the nose skin. Total Time = 2 hrs.

Attaching the "L" Angle to the Horizontal Stabilizer Bottom Skin

10/23/11 - Aligned elevator hinge brackets (75T2-7) on the hinge pin and drilled and clecoed brackets to the horizontal stabilizer. Aligned the elevator so the ends were equal distant on the horizontal stabiler. Filed down more of the horizontal stabilizer horn so the elevator completely pivots on the hinges with free travel throughout. Attached the "L" angle to the horizontal bottom skin. Total Time = 5 hrs.

Elevator Joined to the Horizontal Stabilizer

   Total Elevator Assembly Time = 64 Hours
