Finally I riveted on the aft deck. You will recall I leveled the fuselage and ensured no twist earlier, but did not rivet the aft deck on until after I worked the rudder cable fairing, some holes for wires. I wanted to do the work under the aft deck without it in place.
Those things are done and so the aft deck got riveted. I squeezed most of the rivets and bucked a few.
