Drilled rest of the R/H wing bottom skins to a #21. Taped the tie down ring to the height I wanted. I'll drill the holes after I remove the leading edge skin. Opened the cutout for the strut bracket bolt a little more so the bolt can clear the skin. Cleco the trailing edge skins to the rear spar. Needed to remove more material from the inboard trailing edge skin outboard end where the outboard trailing edge overlaps it. This took awhile to get the two pieces to fit good. Cleco the flaperon brackets and L angles to the ribs. Drilled the L brackets to a #30 in the skin. Taped the skins where I'm going to prime. All set to remove the skins to sand the edges, debur, and prime the mating surfaces.
