In the previous session, all the Hinge Brackets for the Left and Right Aileron’s were separated and edge cleaned. Tonight, the Brackets will be “fitted” to their respective Nose Rib. The Outboard Hinge Brackets to Nose Ribs are the upper two Ribs in the picture below. The Inboard Hinge Brackets to Nose Ribs are the two Ribs in the bottom of the pictures. The two A-1004-1R and A-10041L Nose Ribs in the middle will be used to attach the Counterbalance. Initially, the #30 holes common to the Brackets and Ribs were final-drilled. Next, the holes in the Brackets (on the opposite side of the Ribs) were countersunk to accept the head of a AN426AD4 flush rivet. These pieces are now prepared and ready to riveted together. However, prior to doing that, I am going to a treat the parts with Alumiprep, Alodine, and Akzo Primer.
So, moving on. The next step in the plans is to separate the Main Ribs as shown below.....
The two A-1005-1L Main Ribs are shown on the right and the two A-1005-1R Main Ribs are shown on the left.....
.....and here they are separated. I used my cutoff wheel to separated the parts.
