We spent another hour on the left outboard flaperon. The splice rib and associated bracket were drilled into place, the whole assembly was deburred and then protected from corrosion. The splice rib and bracket were riveted into place using the hand riveter.

After some exploration the electric drill does not differ from the air drill in regards to producing burrs. The electric drill is less ideal than the air drill in three main ways. 1) The chuck area is larger and thus much harder to get into tight spaces. 2) The drill is MUCH heavier so when it punches through the metal the chuck hits the metal skin with more force, and thus the protective rubber washers much faster and it is much easier to damage the skin. 3) The drill takes a long time to spool down after use making several seconds of delay required before moving onto the next hole. On the upside the drill generates much less noise.

Project Status:
Flaperons: ( right outboard DONE! ) 11.5 hours spent ( 1h, 1h, 1.5h, 3h, 6h )
Paint Design: 2 hours spent ( 1h, 1h )

Horizontal Stabilizer DONE!: ~28 hours spent, 3 pieces replaced ( 3h, 2h, 2h, 2h, .5h, 1.5h, 3.5h, 1.5h, 5, 4.5, 2h, .5h )
