Having done this already on the left flap, I knew just how approach this riveting session. This right flap should go a lot faster. I'm beginning to think that the technique of doing the left side first on any left/right assemblies, is the way to go. This way the right assemblies done after the left usually take less time and turn out better looking when completed.

The instructions say to "Rivet the FL-906B Plate to the inboard FL-905 Rib; install the platenut; and rivet the Rib to the FL-903 Spar". I don't agree with this. If you put the FL-906B reinforcement plate on first, the short rivet at the end of the plate that holds the platenut in place is almost impossible to squeeze without stove-piping(bending over) the rivet. So I put in the aft-most rivet to secure the platenut first.
Now it's time to rivet the reinforcement plate onNow it's time to rivet the reinforcement plate on
I put in all the 1/8 inch rivets and then put in the last small rivet, holding the other end of the platenut in place. You can see in this photo just how close the reinforcment plate is to that platenut rivet. It just doesn't allow you to center the squeeze for a proper riveting session.

I was lucky on this one. My good buddy Norwood just happen to drop by to visit and I put him to work, bucking the puppies.

I wanted to use my pneumatic squeezer, so I added some washers under the flat head die to increase the gap of the yoke to where it didn't hit the spar when a rivet get's squeezed.
