How it works:
You'll notice the ring clamp has a round jaw - for rings and curved shapes - and a straight jaw - for straight-sided shapes. Most models feature leather pads inside the jaws, and a separate wedge that can be inserted into either jaw and secured with a few taps on the bench top. Simply insert the jewelry object or part into the desired jaw, insert the wedge on the other end, and tap it on the tabletop. Once secured, you can brace the ring clamp against or in the V-slot of the bench pin to support your work as you file, sand, drill, set or polish.
Some specialty bench pins even feature a hemispherical opening specifically designed for the ring clamp to rest in. Another plus: any wood ring clamp can be modified to a specific task by sawing it or changing the jaw shape as needed. You can create several modified clamps to assist you with repetitive tasks or production work.
