I reached another milestone today – the first actual rivet installed! I riveted the vertical stabilizer forward spar doubler to the forward spar. This step included 6 AN426 rivets set flush on the aft side of the spar and 4 AN470 rivets also set with the manufactured head on the aft side of the spar. I used the pneumatic squeezer to install the rivets with good results.
I finished the session by clecoing the rear spar, rear spar doubler, and hinge brackets together for the next riveting step.
