Riveted Horizontal Stabilizer front spar

I riveted the stringers to the in-board in-spar ribs and stringer web.

Then I clecoed and riveted all of the in-spar ribs to the front spar, and the two outside nose ribs. I got everything done with the pneumatic squeezer, which was easy given that I have a sheet with all the settings. Just twist the adjustable set the right number of turns and then squeeze away. These were all 4-4 rivets except for 8 4-5 rivets where the rivets go through the spar, spar cap, and then the rib.

Next step is to start riveting the nose ribs to the skins.
