Completed steps 1-4 page 23iS/U-06for the left skin. Deburred and primed. Completed steps 1-4 on the right side. Need to complete debur and priming.
Step 1: Cut out the wing spar penetration holes in F-01270-1 to make F-01270-L-1 & -R-1. Started by marking out the shaded areas labeled in Figures 1 and 2. Step 2: Drilled a large hole inside the hatched areas shown in Figures 1 and 2. Used snips to cut close to, but not at the edge of the hatched area. Snipped around a final time removing material up to the trim line around the hatched area. Deburred the edge of the hole. Step 3: Clearly marked F-01270-L-1 & -R-1 left and right! Step 4: Dimpled the screw, then the rivet hole in F-01270-L-1 & -R-1 as shown in Figures 1 and 2.
