Close up left wing

The left wing top skins were riveted in place. I enjoyed the huge payoff of dealing with the spar rib mount flange tolerance error months ago. The skins lined up with the ribs with negligible forcing and only a handful of cases where 0.1 or so of misalignment of rib to skin holes needed to be reamed out. Oil canning is absent, except for a little bit of it around rib 8 where the skins join. As documented in another post the improved skin 3-4 connection went off without a hitch.

The only issue I ran into was some some forcing and cleaning needed to get the front flange holes of rib 3 to match the skin. When this was done I noted that rib 3 itself has a slight oil-canning mode. I may deal with this.

Also I had to clean typically 0.2mm misalignments between the rear part of the step on skin and ribs 201-204, where some forcing did not prove sufficient.
