I didn't take any pictures or do a write-up, but yesterday I prepped and primed the aileron skins and stiffeners.
Today I started out by back riveting the stiffeners to the skins. I sure wish all riveting was this easy! Back riveting goes really quickly and always turns out really nice.
The next step was to cleco the end ribs to the spar and match drill to the bottom skins. The ribs are not symmetrical, so I had to be careful to ensure I got them in the right place so the skin holes would line up.
After the skins and ribs were match drilled, the skin holes got dimpled with the squeezer. I dimpled as many holes in the ribs as I could with the squeezer, but the last couple were too tight to get the squeezer yoke into. The close quarters dimple die worked great though - just a female die bolted to the bench and the male die inserted into the ram from the C-frame dimpler. A couple of hits with a heavy hammer made nice dimples.
In order to match drill the top skin to the rib, the bottom skin has to be able to lie flat on the table. The only way to do that is to temporarily rivet the rib to the bottom skin, since clecos would get in the way. So I put two rivets in each rib, just barely set to make them easier to drill out later.
Now is time for the part I need to figure out how to do - wrapping the leading edge into shape and clecoing it to the top skin/spar. I clecoed the bottom side of the leading edge skin to the bottom skin and spar, then slid the clecos off the table and clamped everything down flat.
Of course, the instructions failed to call out that the nose rib and counterweight tube should be in place, so I had to back up and get it clecoed in. With the tube in place, bending the leading edge around and connecting it to the top of the spar is going to be a fight and a half. It is tight! By hand, I can only get the holes to be within about 1/4" of each other. So I'm going to have to figure out another method for this. Time to do some research and figure out what others have done!
