Brief Description: Flap drive plates and support jig
In making the elevators I realized that it would work better to drill the holes if there was some sort of support under the skin. Therefore for the flaps I build a support jig that simulated the flap ribs being in place. This allowed me to measure, center-punch and drill the holes with the flap skins being supported.
It worked extremely well.
I also located the flap drive plates on the both flap root ribs so my boys could help the next day with drilling.
