Frank came over today and we riveted the inner top skin on the left wing. Frank needed about 5 minutes of instruction and we were off. I don't count rivets or holes anymore, there are just too many, and I'm not sure I want to know how many holes I've debured or how many rivets I've set. So Frank and I did the entire inner skin in about an hour. All of the rivets were set perfect except about two or three. Just about par for the course. Frank was a great help. Thanks, Frank!
