Image 3 shows an angle that I needed to wait to rivet. This angle piece is riveted on the flap actuator channel at an angle, not parallel to the channel flange.. The angle is determined by pre punched holes and by putting the whole mechanism together. It was tough getting it all together with the fuselage upside down. The plans have you extend the actuator motor rod half way as seen in image 1 to determine the angle of the angle piece and the angle of the hole going through the channel. All good, rivet it.
