Finished riveting spar stiffeners to rear spar using pneaumatic squeezer. Love this tool. Riveted elevator hinge brackets to rear spar. Struggled a bit getting a proper squeezer on the -7 rivets as they seemed a little long but what was speced in the planes. Mic'ed them and all within specs. Bolted center bearing block to spar, will need to borrow a inch-lbs torque wrench to finalize.
HS-609PP stiffeners to HS-603PP rear spar
Rear spar completed except to torque bearing block bolts.
