Disassembled, deburred, primed and riveted bars into spar channel. Squeezed first rivet (ouch!), then drove the rest.
Riveted outboard 4 elevator hinge brackets to spar.
Bolted center elevator bracket and bearing to spar. You're supposed to torque these to 20-25 inch-lbs, but since my present torque wrench doesn't read that low, I made an intelligent guess. I'll add this task to my "Punch List" and check it later.
