November 29, 2004 - Aileron

The spar and rib assembly with the trailing edge skin clecoed on. 
The aileron with the leading edge skin clecoed on.  Notice the pipe in the leading edge.  That's a steel pipe which weighs a ton and acts as a counterbalance for the aileron.  Ready for match drilling.
In this picture, I'm using my 12" long drill bit to drill a hole through the nose rib flange and the counterbalance weight pipe.  To get to the pipe, the drill bit goes through a hole in the spar. 
After match drilling everything, I disassembled the aileron and started deburring and dimpling.
I primed the counterbalance weight pipe and the nose rib.  Then I pop-riveted the nose rib to the counterbalance weight pipe.  I gave the pipe two coats of Mar-Hyde primer since it's dissimilar metal to the aluminum.  For the inside of the pipe, I just sprayed into the pipe from both sides.
