I deburred and dimpled all the ribs. The left LE contains the stall warning system. I also did the access hole doubler and panel. I read through the stall warning system drawings as well to make sure I wasn't missing anything. I finished by dimpling the Left skin also. I used the new tank dimple dies for the ribs. I recently ordered the "sub structure" dies from Cleveland but haven't gotten them yet. I'll use those on the right side and see if I notice any difference.
