Brief Description:    Pilot drilled bottom skin to the main spar extrusi
Pilot drilled bottom skin to the main spar extrusion. Used a piece of wood as a drill stop so that the drill would not would not make smilies drilling through the thick aluminum.

In image 1 you can see where the cleco is above the bolt. Other builders have removed the Rib Attach Angle and rounded out the plate to create an area for the rivet. I had the same problem on the bottom of the main spar. See the cleco below the nut in image 2.
