Having assembled the ribs to the spars and holding in clekos, it was time to place the stringers.
I found that clamping two of the ribs so that they could not move, making sure they were vertical and square to the spars, made it much easier to slide the stringers into place and drill for the dimpled flush rivets that hold them.
I kept a record of the locations wherein I had made the joints in the stringers on the left wing & duplicated that for this one.
