Started working the ribs for the vertical stab and rudder. I also jumped ahead a bit with the instructions to fit and drill the half inch aluminum edge that is used to attach the rear inspection panel. I read somewhere where one builder thought it would be easier to do the fitting and drilling of those before the rib was Hysol'd on to the frame. That sure made sense to me so I followed suit by doing the fabrication, drilling and fitting of the pieces. Got them primed and painted so they are ready to install once I get all the ribs installed permanently. Pressed on with fitting the rest of the ribs on both the vertical and the rudder making sure they were lined up with each other (so they look cool when I cover them). I built the stiffeners for the ribs, removed the ribs from the airframe and Hysol'd the stiffeners to the ribs so that I can move on to giving them a coat of lacquer tomorrow.
