I begun riveting the bottom skins. Some rivets are quite difficult to reach. I adopted the sequence described in the manual, which albeit very short seems to work.
I begin by the rear part on the fusleage side of the wing and work in an fan type pattern toward the front and the tip.
The skin must be lifted to reach some rivets towards the rear. Care must be taken not to fold the skin which would be a big problem.



This is the fuselage side access, the right hole is too small for my arm which is a problem for some rivets.



After almost four hours, the first skin is almost done (some rivets missing on the main spar). I begin installing the second skin and work in the same pattern, but only finish half a bay. This skin is more flexible must also more fragile.
