While waiting for parts I decided to rivet together some of the forward structure. Removed the center rib and angle suports and cleco'd together on the bench. Put bolts and nuts in to hold the aft end. Was able to rivet the 7108B angle to the rib with the squeezer. Also used the squeezer for the three aft rivets on 7108C. Couldn't figure a way to squeeze or buck the forward three rivets so I used Cherrymax here. Riveted on the F-793 left and right vent brackets with my new swivel head flush set.
