Once the inboard and outboard skins were secured in position with some Clecos, the W-1202R bottom skin was prepared for assembly by removing the blue protective film from the rivet lines followed by a quick smoothing of the skin’s edges with the 3M foam sanding blocks.
Placing the W-1202R center bottom skin onto the right wing’s skeleton.
The W-1202R bottom center skin was then secured onto the right wing skeleton using the same method mentioned above followed by adding many more Clecos to all three skins. This is a slight deviation from the plans which would have the builder Cleco and then rivet one skin at a time (which I suspect is due to the small number of Clecos Van’s says is necessary to build the RV-12). The DOG Aviation procurement department purchased far more Clecos then the suggested minimum, so all three skins will be riveted at one time. Knowing from having worked on Pete’s RV-9A (which incidentally has just received an airworthiness certification from the FAA, so first flight will be any day now - congratulations Pete!!!), one can’t have too many Clecos when building an all aluminum aircraft.
Securing the right wing’s W-1202 bottom center skin onto the right wing’s skeleton by using a center punch to help align the underlying rib before placing a Cleco into the adjacent rivet hole.
All bottom skins now secured with Clecos and ready for a mass riveting session.
