With the wings on the jig i was able to cleco on the top skins of both wings and managed to match drill all holes of both wings (top skins only though) It wasnt too bad, but im about out of clecos so i ordered another 250 from spruce to do the bottom skins. The inboard skin gets a thick aluminum doubler plate concealed behind it and match-drilled in place. This is where you will be allowed to step on top the wing for entry and exit. There looks to be some tough beveling ahead where the skins overlap.... and tons of deburring.
