Brief Description: Riveting the aft spar into the vert stab
Next we installed the aft spar, riveted it to the skins and the ribs. We could easily line up the top rib for the pneumatic squeezer, and I used the rivet gun for the bottom rib's dome-topped 470 rivets with the tungsten bucking bar (see photos).
Almost done....
