Brief Description:	working on left wing spar
I put all of the rivets into the rivet holes to keep them lined up during the drilling of the bolt holes for rib attach angles and 4130 steel reinforcing plates. I used a different approach for clamping the rib attach angles, shown in the photos below. I got all of the one-sixteenth inch thick rib attach angles mounted. I did not get the one-eigth inch angle at the root yet.
