Repaired the primer coat on the rudder frame. I riveted the trim reinforcement plate to the left Elevator skin. Primed the reinforcement plate once riveted on. Started work on the C/B weights and end ribs. Also the diecided to run the elevator spars in tandem when I can. Clecoed and drilled the control reinforcement plates to the elevator spars, clecoed and drilled the end ribs and C/B ribs.
