Brief Description: Rivet Stiffeners to Skin Part 2
The stiffeners are back riveted onto the skin. This was pretty easy to do and I got great results, except "The Curse" hit me again. One of the rivet heads was on the edge of the plate and when I shot it and I twisted the dimple as shown in the second picture. I thought I was being pretty good about checking and double checking the rivet position on the plate, but obviously one got away from me.
The shear clips are riveted to the right hand skin/stiffeners with the upstanding flange on the forward end to attach to the front spar. Cue "The Curse". I was being very careful to check the position of the stiffeners and clips as I riveted them to make sure their orientation was correct. It was late and I was tired after a long session. I can't believe I actually installed the last clip with the flange facing aft instead of forward.
I'm too tired to fix these issues tonight. I'm not yet sure how to straighten out that messed up dimple. The fix for the mis-installed shear clip is obvious though. The two LP4-5 blind rivets have to be drilled out, but I need to understand if there is any difference in drilling out a blind vs. a solid rivet.
Fortunately, at work we have some training going on with an AOG team (Aircraft On Ground). These guys are expert aircraft mechanics and have seen everything. I'm sure they'll give me some good tips.
Rivets set in place and rivet tape placed over the manufactured heads.
This is what happens when the rivet head is partially on the back bucking plate.
Stiffeners and shear clips riveted into place. One clip was installed improperly.
