I started this morning... (2:30 am) could not sleep for some reason, by backing riveting the rubber stiffeners to the left and right skin. Turned out really nice.
I then installed the skins to the rudder skeleton. Everything lined up well. I continued to fit the rudder horn R-405PD and rudder brace R-710. Drilled / Dimpled the aft three holes on the upper skin to #30. Dtrilled the E614-020 counterweight to R-912 rib. Dimpled the trailing edge skins. countersunk the R-916... That was a pain in the butt...
