Brief Description: Forward fuselage skin
|
|
Today, because I finally received my replacement 120-degree countersink bit, I decided to attach the aft baggage door strip, and then drill and cleco the forward skin on. The new strip was match-drilled to the old one, deburred, and attached with LP4-4 blind keeper rivets (hence the need for the 120-degree countersink bit.)
Next, the skin was laid on the bulkheads. This time, I VERY carefully pushed the skin into the proper position and tightly duct taped it to the fuselage sides. The duct tape made a big difference. I got the sides of the skin even on both sides and, with a bit of persuasion, sighted the longeron centerline marks through the prepunched holes on both sides. (Last time, the skin was uneven by about 1/16" between sides, not enough to be a structural or even a noticable cosmetic issue, but enough that it would have driven me nuts forever.)
I clecoed the skin to the firewall using the existing holes, then drilled and clecoed the skin on as before, middle bulkhead first, and from the center down each side. It went very smoothly. The resulting slightly figure-8 holes in the flange will be addressed with oversized rivets.

The fuselage skin was held down tightly with duct tape and straps.

Yes, that's Patty Wagstaff overseeing the construction.
