Now that all the skins have been match drilled, it was necessary to remove the skins and the underlying framework. I deburred all the holes in the skin, the bulkhead side channels, gussets, fwd fuselage ribs, longerons and longeron gussets. It was necessary to use the rudder pedal drill jig to place holes into the F1013 longeron. also Needed to match drill the #30 holes between the firewall upper and lower angles and the associated upper and lower fuselage channels. All of the above structures that mate with the skin needed to be countersunk for 3/32 rivets including the underlying center section side plates.
