Right hs skin in jig, preparing for skin drilling full size
I cut out the airfoil shape in the two pieces of plywood supplied in the kit and screwed them to 2x4's. Then I put the right hand skin in the jigs, and put in the nose ribs. The inside rib was quite difficult to get in, until I fluted the end of the rib some. After that they all went in very easy. Everything lined up perfectly. Quite amazing.
Removing protective plastic on left hs skin full size
Here I am removing some of the blue plastic on the inside of the left hand hs skin. I did the same on the right side previously, but didn't take a picture. After this, I assembled the left hand hs to match drill it's skin also. This time everything went together perfect, no problems putting in any of the nose ribs.
