Finished riveting hinge brackets, HS-413. Found that -5 rivets were too long (called for in the plans). -4 were too short. Cut rivets down to -4.5 length. Rivets kept bending when using pnuematic squeezer. Had to drill out some rivets twice. Drilled out -4 rivets that Dave had installed. Ended up using rivet gun and bucking bar. Because of the numerous times rivets were out, drilled a center hole in each -413 bracket and added a 5th -4.5 rivet.
