!!!!!Happy Easter!!!!!
Here we go.....riveted the Rudder Skins to the R-912 Counterbalance Rib using AN426AD3-3 flush rivets and the pneumatic squeezer. The E-614-020 Conterweight was then installed on the Counterbalance Rib using MS21042-3 nuts, NAS1149F0363P washers, and AN509-10R16 bolts. The Counterweight had to be trimmed slightly to allow clearance for the shop heads of the forward most rivets on the Counterbalance Rib.
Next, the Rudder Skins were riveted to the Spar using AN426AD3-3.5 flush rivets. I had to shoot these rivetes using the Rivet Gun and Bucking Bar because the distance was to great for the squeezer yoke due to the forward part of the Skins. This part of the Skins will be rolled and riveted together in a future step to form the leading edge of the Rudder. You can see the area I'm talking about in the picture below.....it's the part of the Skin that has the six empty holes.
I Final-Drilled #33 the six aft most holes of the R-903 Top Rib to allow these holes to accept MK-319-BS flush pop rivets. The Top Rib was clecoed to the Spar and Rudder Skins and is ready to be riveted together during the next session.
