A bench pin is a notched piece of wood that is attached to your work table or work bench to aid with sawing. It also helps steady your hands and tools to do intricate work in small spaces. You can snugly anchor numerous tools, like the ring clamp and pliers, into the notch to aid with filing, polishing, and setting gemstones.
This is not notched in the middle and you will need to saw the notch. The pin is inserted into a metal holder and secured with a screw on the side. The metal holder is then bolted to the bench.
