Dusted off left spar and placed rivets in spar. Rivets that only went thru spar and flange strip W-606C were turned around so that machine head was on the spar web side to prevent gapping. Spar and flange strip still were spread apart some but not as large a gap as on the right spar when they were riveted during the next session.
Shortened 6-25 rivets and taped all rivets in place.
