Deburred, dimpled, and back riveted stiffeners to right elevator. Worked on both frameworks to prepare them for final skinning. Riveted doublers and platenuts on right elevator spar. Primed tip ribs for same elevator. Drilled holes in steel parts that actuate both elevators to 1/8". Also, trimmed lead counterweight for right elevator per instructions. Will need to drill it out for bolts for attachment to tip ribs.
