ABSTRACT:
The present invention relates to a method and apparatus for minimizing undesirable gaps in riveted assemblies. The method includes the steps of selecting a rivet having a head and a tail with identical forming characteristics, positioning the selected rivet in an assembly that is countersunk on one of two sides, and applying a force over time to the head of the rivet and a force over time to the tail of the rivet that are equal and opposite, compensating for force unbalancing characteristics of the countersink.
