Began today by riveting the E-703 and E-704 end ribs together. I alternated the factory heads to even riveting stress and try to keep the structure a straight as possible. Riveted the E-610 and E-611 reinforcing plates to the spar along with the platenuts. Bucking bar slipped on one platenut rivet, so I drilled that one and replaced it. Riveted the end ribs to the spar, used flush rivets for the E-705. Riveted the WD-605 control horn to the spar assebly.
