Riveted frame together and skin to frame. I had to grind down the tip of the squeezer yoke to get enough clearance on the main spar doubler to properly secure the skin. Some of those rivets are difficult to get to and shoot with the gun, I had too many smileys and well I wasn't that satisfied with the final results , I have seen worse. Add On : I just found out about a swivel head flush head tip that would have helped. Another tool along with the pneumatic squeezer I decided to finaly get.
