1.8 Hours -
Stiffener work is really simple, but it is also very repetitive, very boring, and very time-consuming. This evening, I started by final drilling all of the stiffeners to the rear aileron skins. Once this was done, I deburred all of the rivet holes in the stiffeners, scuffed them and dimpled them. These parts now need to be cleaned and primed before they are riveted to the aileron skins.
I didn’t want to clean and prime the stiffeners this evening, so I pulled out my soldering iron and removed some of the blue vinyl from the rear aileron skins. On the outside of the skins, I removed the vinyl from the stiffener rivet lines. All the vinyl was removed from the inside surface. The only reason I did the strips on the outside (rather than removing all of it) is because I’ll be back-riveting the stiffeners and I don’t want the back-riveting plate to scratch the skin.
