This weekend, I disassembled the left wing from the jig. During the process, I photographed EVERYTHING and took notes in the assembly manual so I had a good record of where the original builder left off. I found a few things that surprised me, not in a bad way, but more in a "huh" way. For instance, mid-span on the main top spar cap, there are a number of holes that were not countersunk. I am guessing he either stopped and didn't pick it back up - or was unsure of where the transition between the different skin thicknesses occurred so he left it un-countersunk to avoid a mistake.
I was impressed, however, with the in-place "notes" he made on the parts. Countersink depths, rib numbering, etc. right on the parts. Reminded me how important it will be to maintain correlation during priming! And made it easy to understand where in the assembly manual he stopped. So far, I have only noticed 2-3 places I need to back-track, but nothing scary.
As I mentioned in an earlier posting, I followed through on my intentions and packed up and labelled all the wing components. I am moving on to the ailerons and flaps. I am confident this is the right decision as the parts are smaller and more benign than the wing. If I screw up here, it's a much cheaper fix! Plus I am considering building the left/right pairs of things concurrently in the interest of continuity. Builders disagree on whether that is really a benefit, but I think it will work for me.
