ABSTRACT:
A method by which a generally elongate right cylindrically-shaped part is precisely machined and shaped includes the steps of drawing a disc blank into a cup-shaped blank, subsequently drawing the cup-shaped blank a successive number of times to form a generally elongate right cylindrically-shaped part having a finish diameter and a finish length, cutting the generally right cylindrically-shaped part to create a desired edge configuration and to establish a finish diameter for the part, and working the sidewall of the right cylindrically-shaped part to create a desired pattern therein, such that the part produced may be used, for example, as the base shell for the swivel in a lipstick case.
