(1) Clecoed on upper left outer skin and leading edge (2) Adjusted jig to remove wing twist (1-5/16" +/- 1/32" each end of spar) (3) Riveted leading edge rib flanges to main spar using LP4-3 pop rivets. Used this technique based on experience of Dan Checkoway who got the same guidance from Van's Aircraft to use these pop rivets, if desired. Had to grind down the top of a cheap pop-riveter to get the rivet head seated fully. (4) Used the pneumatic squeezer and 470-4-5 rivets to squeeze the farthest outboard attachment points. (5) Used the squeezer again to rivet the leading edge skin to spar. Did the wing bottom side first. Then removed outer main skin and riveted top side. Once complete, I reattached the outer main skin w/ clecoes.
