Correct, Rojelio. The punch that forms the cross-shaped blank is made up of four pieces of steel rod held together tightly in a bundle by a steel cylinder at the top. The small channel remaining where the four rods touch has been bored out to accept the plunger rod that actually forms the cap. A bail mounted on the arbor press swings down to press the cross blank punching die, and then swings up again to allow the press itself to push the cap forming punch down through the center of the cross punch, pressing the cross-shaped blank to form it into a cup. Then the bail is swung down again to catch the cylinder which holds the four rods of the cross punch together, allowing the whole plunger assembly to be lifted free of the die assembly to allow advancing the copper strip in preparation to form the next cap. I used the cross forming punch to make the die with which it operates. A single hole the diameter of one of the punch rods was drilled straight through the two steel blanks that form the die that cuts the cross shaped blanks. A single rod from the cross punch bundle was pushed down through the hole drilled in the steel blanks, and a second rod was removed from the bundle, with the space remaining used to guide a drill bit to bore a second hole. The bit was removed, the rod was replaced, and another rod removed to allow a third hole to be bored, followed by a fourth. All four rods were set into their respective holes, and then the hole for the cap forming plunger was bored down through the bundle of rods and steel blanks to form the die that cuts the crosses, and on through the 1/2 inch steel blank to begin making the die that forms the actual percussion caps.
