Dad and I have been working over the last few days on closing up the wings. The bottom skins are slowly going on. Took a while to work out the approach and settle into the task.
We have added one 'ding' to the skin near the rear spar that is quite ugly, but not structural. Pretty upset about that. Also have some slight 'oil canning' in one panel. Seems like this is very difficult to eliminate. The holes were lined up perfect on the pre-drill and then under bucking some small amount of canning.
