Tonight I match drilled the right ribs to spar, match drilled right aileron leading edge/trailing edge skins to skeleton (spar + ribs) and drilled counterbalance pipe to #30. The counterbalance pipe is a glavanized steel pipe that spans the length of the leading edge of the aileron to counter the aerodynamic effect. It weighs over 3 lbs. I also drilled bottom of skins to #30 to accept the blind rivets. Blind rivets must be used because after the top skin is riveted, there will not be access for a solid rivet,
Only one picture as I forgot to take more...it shows the right aileron after being match drilled...except the bottom skin is still at #40.
