Working the Rivet Gun
# The rivet is loaded into the rivet gun head and placed into position where the metal is to be joined. The trigger is pulled and the rivet is forced by air through the metal. The backer buck squashes the tail of the rivet against the backside of the metal securing it in place. The rivet gun is then reloaded with the next rivet and the process is repeated.
