With some time to get back to building, I decided to finally start attaching the Outboard Leading Edge section to the right wing. I had been delaying this step as long as possible because the wing becomes much more difficult to move and store once it can no longer rest on its spar.

After trial fitting the OBLE a couple of times onto the wing and trying to cleco through the spar and into the OBLE ribs, I realized that I needed to enlarge the notches of the 2nd-most inboard rib a little more to fit around the steps in the spar. The instructions advised you long ago to remove a certain amount from this rib prior to assembly, but I apparently didn't remove enough so I got out the dremel and files and removed another couple of millimeters from those ribs.

With that done, I could cleco the OBLE back onto the wing and then begin installing all of the blind rivets that go through the spar webbing and into the OBLE ribs. This went pretty smoothly, though I did have to use a piece of trailing-edge wedge to set a couple of the blind rivets that were too close to the edge to fit my rivet puller straight on.

Then I squeezed all of the flush rivets that hold the underside of the OBLE skin to the wing spar flange, since these were easy to do with my hand squeezer.

What's next? I'll need to get out the air rivet gun and buck the rivets for the innermost rib, and then see if I can do any of the flush rivets on the other side of the skin (I suspect I may need assistance from another person to help rivet).
