I started cutting and adding in some of the new skylight tubes today.
I cut a notch into the tube to make it match the mounting area.
Mysterious note from the future!
I learned in retrospect that the following picture shows a tube that is ground a little too much. It should have been a little bit taller.
Mysterious note from the future number 2:
The above and below pictures show another problem. I put the tubes in as straight tubes, and they should have been curved slightly. Can you see what I mean? They should probably match the curves in the channels at the wing root.
While I was there, I welded the seatbelt tube in place.
