I got all the various pieces of the aileron match drilled, deburred, scuffed and dimpled. Next step is cleaning and priming.
A significant amount of the time was spent countersinking the metal counterweight pipe. The rivets that hold the skin to the pipe are flush so the skin had to be dimpled by tapping the male dimple die into the skin on top of the pipe. The results were good but once the aileron is installed no one will see them. The rivets are flush for clearance with the structure.
