Brief Description: Making Skin Spar Cutouts and Prepping Side Skins
Cut out the wing spar penetration holes in the F-01270-1 to make F-01270-L-1 & -R-1 by marking the shaded areas in figures 1 & 2 page 23iS/U-06 onto the parts. Then drilling a 1/4 hole inside the marked area. Then used snips to cut close to the edge of the hatched area and then filed the edges to remove material up to the trim lines. Deburred edge of holes. Marked parts left and right.
Dimpled the screw holes and flush rivet holes per same figures on the top forward ends.
Riveted F-1202L to F-1202E-L & -R. Cleco'ed F-01270-L-1 & -R-1, F-01270A-1 and F-1270D to the fuselage. Aligned the aft edge of F-01234-L-1 & -R-1 with the forward edge of F-01205B-L-1 & -R-1. Aligned the vertex of the F-01255-L-1 & -R-1 with the upper edge of the F-01270-L-1 & -R-1 per figure 2 page 23iS/U-02 and clamped both parts together. Aligned the outboard edge of F-01205B-L-1 & -R-1 with the vertex of F-01255-L-1 & -R-1 and clamped both parts together.
Match drilled #30 all holes common between F-01270-L-1 & -R-1, F-01270A-1, F-1270D, and F-01255-L-1 & -R-1. Match drilled #30 all holes common between F-01205B-L-1 & -R-1 and F-01255-L-1 & -R-1.
Machine Countersunk 120 degrees the hole locations in the F-1270D that use flush rivets to make F-1270D-L & R per Figure 2 page 23iS/U-10.
Removed and deburred F-01255-L-1 & -R-1, F-01270-L-1 & -R-1, F-01270A-1 and F-1270-L & -R and touched up primer.
