Created by jewelry maker, designer and teacher Jayne Redman, the innovative rotational bench pin provides the ideal work surface companion for your jeweler's bench. With this standard mounting hardware, you can attach either of the generously sized (5"W x 6"L) Jayne Redman bench pins to your bench and enjoy the ability to rotate the pin to the exact position you need for the task at hand. Bench pins (included) are made in aluminum and in purple heart wood. Choose the material best suited to your task. To switch from one to the other, simply unscrew one pin and screw in the other. If you need to change pins often, an adapter is available so that you can attach the second pin to for added convenience. Then, you simply change the entire assembly in a few seconds by sliding one off of and the other onto the mounting bracket. Once in place on the base, you can rotate the pins 360°; especially helpful when you're cutting blanking dies.
