I decided to move onto the wing spar section, so the first task was to drag the huge spar out of the shipping box and set it across two tables in my workshop. I then had to cut 4 pieces of J-channel aluminum to specified lengths (with a Dremel tool), then clamp them to the sides of the spar, and match-drill dozens of holes through them. Once fully drilled (which required swapping the lower pieces onto the upper side to fully drill), those 4 pieces can be set aside for a later section.
Then I had to final drill and countersink dozens of more holes along the flanges of the spar that would later receive nutplates. Once all of those holes were prepared, I started laying out all of the nutplates into their appropriate locations with clecos. Unfortunately, it looks like among the backordered parts in this kit are several dozen of some of the nutplates. I'll be able to attach the ones that I have, but not all of them for this section.
