Riveted the last two ribs onto the main spar. I started alone and on the second rivet I didn't set the gun squarely on the rivet and got a big "frownie" across the head of the rivet. I filed the rivet head to get a flat srface to start the drill and used the rivet removal tool to drill the head successfully. Protected the spar with a tongue depressor while using side cutters to remove the body of the rivet. Remaining rivets went well with Frances helping. Once done riveting the ribs we moved the spar off the bench and set it on blocks so I could cleco on the rear spar. Put cleco's in and marked with tape those we'll rivet later in conjunction with the aileron and flap gap fairings.
