In this session, I went about finishing the riveting of the fluish rivets on the lower skin of the Horizontal Stabilizer. These all involved positioning the bucking bar inside the skin with one hand and holding the air rivet gun in the other on the outside of the skin. As with the previous session, there were 4 different length rivets that I had to keep track of and ensure they went into the right holes.
After that was done, I moved the rear spar assembly out of storage, positioned it between the skins, and then clecoed it into place.
What's next? Squeeze all of the final rivets on the rear spar, and some blind rivets for the ribs.
