18-03 step 3 - Rivet nose ribs to counterbalance. Did both wrong. The nose skin holes were not at the place were I suspected them (Discoverd this during nose skin installment). Had to drill out the rivets and turn the counterbalance pipes 180 degrees, stupid me!
18-04 step 3 - Used C clamps and clecoos to hold the brackets and nose ribs together before riveting. Even with this setup a small gap formed between the bracket and the rib.
18-04 step 6 - Match drilled the actuation brackets and riveted them to the spar. Shop head on the fwd side.
