Chapter 19 - Wings - Part 16

More work today on the left aileron and wing.

Pictured here I have clamped a straight edge on the wing to guide me while cutting out the hinge notches on the top skin of the wing. This ensured that the hinges were all in line with each other and inset the proper amount.
Pictured below is the inboard most hinge with clickbonds test fitted. The plans call for a machine screw and a nutplate to be riveted to the hinge. The ckickbond fasteners are simpler to install and will have a seamless appearance then the wing if finished. This hinge happens to be 8" with three fasteners, the middle and outboard are 6" with two.  
Pictured here is the middle span hinge with showing the clickbond fasteners protruding through the top skin and hinge.
And here is the inboard hinge clickbonds floxed in place with two plies BID. The hinge has a protective clear tape to ensure that any flox or epoxy will not bond the hinge to the clickbond or wing.
