Finished up 5 rivets in the 3rd rib—thought I could squeeze them, but could only squeeze the two in the spar. Clubbed one over and had to drill it out, so shot it with the gun. Then I removed the clecoes from the rest of the skin and peeled the skin back to reach the rear spar in the third bay. Got all but 3 rivets set—the closer to the rib, the harder it is to get your arm and wrist to bend in about 6 different directions, all at the same time! Will get the last 3 and then should be an easy cruse down the rib to the main spar.
