Repeated the process of wing attachment today on the left wing. After riveting the wing fairing attachments to the fuselage I placed nutplates along the inbd edge of the wing for the fairing attachment. Again using motor oil on the bolts and the rivet gun to drive the bolts into place, I had no difficulty placing the bolts. I will clean all oil of the bolt threads before attempting to torque them. The rear and front spars were attached to the fuselage. I then attached both flaps to left and right wings. I adjusted the right flap actuating mechanism.
