Deburred, dimpled, and countersunk HS

Spent some time dimpling, deburring, and countersinking the HS. Rather than simply countersinking the skeleton, I dimpled first and then added a little countersink to each dimpled hole. This yielded much better results than merely countersinking .032 as I did on the VS. According to specs, it is technically ok to countersink a 3/32" hole in .032 aluminum, but in reality it enlarges the holes, so I'll keep on using this process of dimple then light countersink.

Today I finished the left skin and most of the ribs.

Time spent: 2 hours (37 total)
