And here it is prior to sheeting. Look close and you will see how I bonded ply plates to structurally connect the two main cross member parts (F117 and F124). This requires sanding the faces of the two projections that stick out of F124 at an angle that is flush with F117. You will wind up with a perfect flat surface to bond a plate onto to join these critical parts together (right where it counts).
I also didn't like the entire load of the positive flying wires working to pull F124 out of the center section so you can also see how I put a small counter sunk screw through F124 into the rib assembly underneath.
Bottom ready for sheeting
Sheeted. I did not install the F125 plates. I couldn't deduce any advantage to having them. If they were for added strength they were all wrong. Assembly is plenty strong without them
