Learn how to set up and use a clamp-on bench anvil with a pin holder and mandrel groove for jewellery forming, sawing, and filing at your bench.
Quick answer
A clamp-on bench anvil with a built-in pin holder and mandrel groove lets you switch between forming, sawing, and filing without changing tools. Here's how to set it up and use it effectively at your jewellery bench.
Why a clamp-on design works for small workshops
A clamp-on bench anvil attaches directly to your workbench edge, saving space and eliminating the need for a dedicated anvil stand. The single cast iron body weighs about 2 kg, which keeps it stable under light hammering and sawing without being too heavy to reposition. This makes it a practical choice for jewellers who work at a shared or compact bench.
The trade-off is that the clamping surface must be clean and flat. If your bench edge is rounded or has a thick lip, the clamp may not grip securely. Always test the clamp tightness before applying force.
Understanding the three functions in one tool
This tool combines a machined anvil face for flattening and light forming, a holder for a hardwood bench pin, and a V-groove that steadies ring and bracelet mandrels. Each function supports a different stage of jewellery making, so knowing which surface to use saves time and protects your work.
The bench pin is reversible: the flat side supports filing, and the V-slot side guides saw blades when cutting wire or piercing sheet metal. Switching between sides takes seconds.
How to set up and use your clamp-on bench anvil
- Step 1: Attach the clamp to your bench: Position the clamp over a clean, flat section of your bench edge. Tighten the screw until the tool feels solid and does not rock. Check that the anvil face is level and the pin holder faces you. If the bench edge is uneven, place a thin piece of leather or rubber between the clamp and bench to improve grip.
- Step 2: Insert the hardwood bench pin: Slide the pin into the holder until it is snug. For filing, use the flat side facing up. For sawing, rotate the pin so the V-slot faces up — this supports the wire or sheet while the saw blade moves freely in the slot. Do not force the pin if it is too tight; lightly sand the edges for a smooth fit.
- Step 3: Use the anvil face for light forming: Place metal sheet or wire on the polished anvil face and strike with a chasing hammer or planishing hammer. The machined surface leaves fewer marks than a rough anvil. Avoid heavy forging — this tool is designed for light jewellery work. Always hold the work steady with your non-dominant hand to prevent slipping under the hammer.
- Step 4: Steady a mandrel in the V-groove: Rest the ring or bracelet mandrel in the V-groove so it does not roll while you hammer or file. The groove holds the mandrel at a comfortable angle for shaping and sizing. Check that the mandrel sits fully in the groove before striking — a tilted mandrel can damage your work or the tool.
- Step 5: Switch between functions quickly: To change from sawing to forming, simply remove the pin and work directly on the anvil face. To use the mandrel groove, slide the pin out or leave it in place if the groove is still accessible. No tools are needed for any switch. Keep the pin in its holder when not in use so you do not misplace it.
