All of the leading edge ribs have now been glued to the left side of the wing.  I might be getting old, but at least I’m patriotic

 

 

Another view of the leading edge ribs glued to the left side.  I have clamped the left leading edge strip to the top side of the ribs to stabilize them and prevent them from being “knocked off” while I worked on the other side of the wing

 

 

This is a long story, but I had to glue a 1 mm piece of plywood to the right front face of the main wing spar at station 5 and at station 9 because those two leading edge ribs ended up located right on the joggle where the thicker inboard plywood of the spar met the thinner outboard plywood.  This caused and uneven surface where the two ribs were to be glued, so the 1 mm plywood piece was scarfed and glued at the joggles and then sanded flat and smooth to provide a flat gluing surface for the ribs

This shows the 10 mm spruce doubler for the #14 leading edge rib with the holes cut in the doubler and the rib to accommodate the Whelen navigation/strobe light
