Left Rear Window Continued

This morning I finished welding the top track for the aft window. The more difficult section is the aft side of the window. I started that section by moving the stringer attach points. THe lower stringer is going to be out a little bit further, while the upper stringer is going to be in a little bit from original. The aft edge of this window will be the forward end of both stringers now. The aft flange is not a track, since if it was, I wouldn’t be able to get the window in. Instead, it’s a joggle. It will get an aluminum mate later that will capture the window and shape the outside of the window aesthetically. I used a bead roller to make the joggle.

This is the result after a few practice runs. It’s not perfectly straight, but it won’t be visible once the airplane is done.


Here's how it comes together at the bottom

I would have preferred to have a straighter finished product on the top half, but all of that should be covered by the aluminum trim piece, so it won’t show.
