Got up at 5am. Riveted on the 412 hinge brackets. Rivet callout was a bit short, so I went to next length and cut them back slightly to make correct length per the rivet gauge. Bolted on center hinge bracket (411). Used torque wrench and tightened to 28” lbs. Applied orange torque seal to bolts and nuts. Rear spar is now complete. 7PM-back to the shop. Riveted 810/814 angles to the right spar. Had to shoot & buck the 2 flush rivets and 2 others on the 814.
