Today I started off by clecoing the flap braces to the left and right bottom wing skins...then match drilled them. I did the same for the Aileron braces on the top outboard skins. After deburring the newly match drilled holes, I dimpled the rest of the bottom skins. The only skins that I have left to dimple are the left and right top outboard skins. Next session I will finish that and finish the edges, deburr and dimple the flap and aileron support braces. I'll also prime the wing skin rivet lines on the inside of each skin.
