After showing my wife the basic of riveting, she became a great helper for riveting the top main skin. After a few trial rivets, we went ahead full speed. The shop heads all look pretty good. She dinged the spar flange slightly at one location that I need to smooth out using scotchbrite, other than that, she did a great job. We spent about 3 hours to have the inboard top skin riveted in place. We will do the outboard tomorrow.
Grace learned how to buck the rivets
Inboard top skin for the right wing is riveted, except the rivets to the rear spar. They can be squeezed.
