Squeezed inboard Flap brace rivet. Used a 4-10 and cut it down to 4-9 for better fit.
Set the next two countersunk CR3212-4-6 cherry flush rivets in each wing. Really like these rivets . May get some more if I need some structural flush rivets elswhere.
Used my new cherry puller from Cleaveland tools and it is much better than my cheap one I have been using for pulling.
