Today, I completed the one remaining row of channel to bulkhead clips, and then I began working on the rear wing mounts. This inolves making two doublers for each side, drilling to another bulhead, and drilling the wing attach fitting holes. It also involves cutting a hole in the root rib for the fitting. The difficult part is aligning it so the wing attach fitting hole is in the correct position. I used quite a few refernce lines and clamps to accomplish this. I completed the #2 side and have one doubler and the hole cut out on the #1 side. Probably another 4 hours of work.
