Drilled the flap actuator shaft for the safety wire. Drilled the floor for the F-680 bearing block. Fabricated the F-766B, F-766C, F-766D, F-767 and F-785B. I began to fit the flap motor as called out in the plans AN4-16 bolt, but the bolt supplied in the flap kit was a AN4-22... Just a tad too long!!! bummer. I searched my parts bin and could not come up with a -16, so I will stop by the airport and see if they have one on hand.
