Brief Description: Skinning the underside of the left wing
Lots of gunk required on the mating surfaces of the wings - ribs, spars etc. Not obvious from Picture 1, but it's there.
Pop riveting was pretty easy, though a couple of rivets were a bit tough to bed in properly - push and twist with pliers does the job. Picture 2 shows countersink rivets that go into the stub spar on the leading edge. The hole to the right of the (out of focus) cleco is where a duff rivet pulled right through leaving a hole into the wing. I drillled it out with my rivet removal tool, and replaced without problem. Hooray.
