Brief Description: Preped inboad upper wing skin and double for left
Deburred the inboard uppern left wing skin and left wing doubler, Cleacoed in place, the removed a few times to break the lower edge of the wing doubler. The seamer and the handy-dandyrollwer-type breaking tool were both useless--not emound grab with the seamer, and the roller tool doesn;t work well with the dimpled holes next to the break edge. Used the 4" shop vise (smooth-jawed, fortunately) to grip the 1/8in inch of flat aluminum between the edge and the dimples, and was able to be the right amount of break in the edge after a couple of tries. Completed pulling all the leading edge flush rivets, and about half of the remaining rivets on the inboard skin and wing walk doulber.
