- 1. A method of making a series of drawn and ironed easily hand-held metallic containers of the type having a central longitudinal axis and comprising a side wall which has opposed ends and a bottom wall closing one of said opposed ends, said bottom wall having a first portion adjoining said one end and extending inwardly toward said longitudinal axis, and a second portion adjoining said first portion and adapted to have the location thereof adjusted relative to said central longitudinal axis, said method comprising the steps of:
- drawing and ironing a first such metallic container by means of a first cooperating punch and die;
- forming said bottom wall of said first metallic container by means of a first supplemental die to adjust the location of said second portion to obtain a given volume of said container;
- forming additional such containers in accordance with the above defined steps, but permitting the volume of said additional containers to vary from said given volume by a predetermined amount of said cooperating punch and die wear; and,
- readjusting the location of said second portion of subsequent containers to a second location to again obtain said given volume in said subsequent containers, whereby the volume of said containers can be maintained within desired limits without replacing said cooperating punch and die because of wear thereof.
