Riveted all parts to the rear spar channel. Includes the attach plate, root rib bracket (including AN-7A bolts), aileron actuator hole doubler, splice plate, and tip attach bracket.
Most holes were drilled last night; a few things like the splice plate and tip mount angle were pilot drilled, then taken to #30, deburred and riveted.
Drilled all rib attach holes using a rib as a pattern. These were left at pilot size (#40) until the actual wing build-up.
