EXAMPLE:
C. Installation of Solid Shank Rivets.
(1) A large percentage of riveting of airplane structure is accomplished on thin gauge aluminum alloy,
and the work must be accomplished without distorting or damaging the material with hammer
blows or riveting tools. All airplane power riveting is accomplished by upsetting the rivets against
a bucking bar instead of striking the shank with a hammer. To prevent deforming the rivet head,
a rivet set must be selected to fit each type of rivet. The depth of this set must not touch material
being riveted. Parts requiring heat treatment should be heat treated before riveting, since heat
