Today I continued working on the wing covers. I installed all of the lower wing ribs in both wings. I then focused on the left wing. I finished the wing tip ribs which included safety wiring. I then cut the openings in the wing cover for the aileron, flap and rear jury strut attach points. Then I located all of the rivet and bolt locations in the front and rear spars and burned holes through the wing cover with a soldering iron. Next I cut the openings for the front and rear lift strut gusset plates and attached them.
