ABSTRACT:
A method for direct insertion of a headed rivet into a countersunk hole in a workpiece includes placement of a rivet guide in axial alignment over the countersunk hole in the workpiece and blowing a rivet, nose first, through a rivet guide tube in the rivet guide toward the countersunk end of the hole. Air is blown through an annular passage at the exit end of the rivet guide tube into a rivet cavity at the exit end of the rivet guide, to align the rivet axis with the axis of the hole. A vacuum is established on the other end of the hole in the workpiece to draw the rivet into the hole.
