I completed deburring the right hand aileron and moved back to the left aileron. The first step was to mark the small flange so that I could determine what overlap I would have. I looks like I\’m shy about 1/64th from the 1/4 inch edge distance that I would like to achieve. Next I marked the hinge and drilled most of the the pilot holes. I left out the one at the middle rib and the ones at the counterbalance ribs. I\’ll mark and drill these while transferring the holes from the hinge to the skin. I transferred all of the holes in the hinge to the skin. Next, I marked and added the holes through the each of the ribs.
