The location of the F-707B angle interferes with one of the rivet holes in the top skin (see pic 1). When I’m ready to rivet the top skin on I will temporarily drill out the angle to allow access to the back of this rivet. I’ll set this one and then replace the angle.
Before match drilling the top skin I drew a line down the middle of the F-786A J-Stiffener in order to make sure it lined up with the holes in the top skin.
In order to pull the F-6111 rib into place, I started match drilling from the bottom and worked my way up, placing a cleco in each hole.
The ideas above were provided by RV 7 builder Matt Burch. Thanks for the help!
