| We took a ~1"x1"x3" piece of the softer urethane up to the highest power this press can deliver and it returned to its original shape without any problems. (But pressing sharp objects into urethane at high pressure can lead to cuts in the surface.) | We took a ~1"x1"x3" piece of the softer urethane up to the highest power this press can deliver and it returned to its original shape without any problems.

| One technique that is not uncommon can be thought of as "forming on air" can create nicely "pillowed" forms as can be seen in this pendant. | One technique that is not uncommon can be thought of as "forming on air" can create nicely "pillowed" forms as can be seen in this pendant. | ||

| These are disk cutters. A lot of jewelry has circular components because they are quick and easy to make with this equipment. Put a piece f annealed metal between the plates, insert the cutter, whack it with a hammer. This tool could also be used to make custom mechanical shims in brass... | These are disk cutters.

| But when the cutter is over 1" in diameter it is close to impossible to strike it with enough force with a hammer and keep the blow perfectly true. And the dies damage easily. So for larger cutters (1 7/8" on right) and for cutters that are not discs (you can get ovals, hearts, squares, etc but they are expensive) the press is a far better option for keeping the forces aligned. | But when the cutter is over 1" in diameter it is close to impossible to strike it with enough force with a hammer and keep the blow perfectly true.
