I decided to start with the ailerons and flaps since I am familiar with the elevators and rudder and when the wing progresses I want to be able to just install the controls rather than switching back to build these. Here I am match drilling the stiffeners to the skins.

Here all the aileron parts have been primed, again using the PPG DX1791/1792 primer.

Another shot of the internal aileron parts after priming.

The stiffeners riveted to the skins. The back rivet plate has been dropped into a recess in the board that was cut with a router.

Here the skins have been closed up to final shape using the bench mounted brake made of 2x12 boards hinged in the middle. The bends have been made such that the skins sit on the spars with no added pressure.

Installed in v-blocks, the ailerons are aligned and drilled to the structure. The counterweight pipe has not been installed yet.

Another end of the skin/structure fitting, this time from the end.

The completed aileron after riveting together. The pipe has been installed and dimpled per the video where the female countersink is used with the make die to form the dimple.

A shot of the cutout for the middle bracket attachment bolt. Note that I did not install the bracket per the plans - they assume all will fit perfect and doing so would eliminate the ability to align the surface to the wing.
