2 hrs, 13 rivets
Hooked the manometer to the AOA plumbing this morning. This evening, the level went up by 2 1/2 inches. This corresponds to an ambient pressure drop of .2" Hg, which was verified on the barometer. So the AOA plumbing in the aft fuselage is ready to go.
Hooked up the Pitot line to check it.

Then a bunch of odds and ends to finish the forward fuse:
Masked fuselage for NACA vent install. Cut clamping blocks for NACA vents.

Trimmed control cable subpanel bracket to clear avionics cutout.
Drill, deburr and rivet nutplates to control cable subpanel bracket, then rivet bracket to subpanel.

Spent an hour last night isolating the leaks in the manometer. The golf tees used to plug the lines were leaking, through their ends. They were sealing the lines OK, but the tees leaked! The manometer wasn't leaking at all.
