Draw set

A metalworking hand tool used to draw sheets of metal closely together before they are riveted. A draw set is a steel bar with a hole drilled in one end to fit loosely over the shank of a rivet. The rivet is put through the holes in the sheets of metal, and the draw set is placed over the rivet shank. Then the rivet head is tapped lightly with the rivet set. This procedure draws the sheets of metal closely together before the rivet is actually driven.
