Any tips for how to best setup the wing spars for placing and riveting the top skins on? A friend built an RV-9 and talks favorably about having a wing jig, but I don't have that. I did build a wing stand though.
For those who built a wing without a jig, what tips can you give about how to keep it straight and true?..?
