I had to take a week break due to recent ice storms here that caused loss of power and a lot of tree damage. However, now it's time to resume work on preparing the right wing spar for assembly.
I started by measuring and cutting the sections of J-channel stiffeners that will later be used to add rigidity to the uppper and lower skins of the wing. These cut pieces were then clamped onto the flanges of the wing spar and match drilled. The bottom pieces were only partially drilled, avoiding the nutplate sections, and then flipped onto the top flange to finish match drilling all the way.
What's next? Debur these drilled holes, then on to the nutplates.
