Rud: Leading Edge

September 18, 2007

My first leading edge bend was difficult and produced so-so results. I ended up using strips of duct tape to hold curved edges together. Then I alternated the stripes adding more and more tension on each strip to “walk” the holes into alignment. 

–Rolled and match drilled rudder leading edge 

E: Drilling, Deburring

September 16, 2007

–Match drilled left and right stiffeners to skins
–Deburred right elevator skins

Upon review, I don’t think I’ve been doing a good enough job deburring and rounding the edges of the skins thus far. Starting with the right elevator.
