Learn the correct technique to use a chasing hammer for repoussé and metal forming. Step-by-step guidance for controlled doming, texturing, and smoothing.

Quick Answer

A chasing hammer with a slightly convex bow face distributes impact evenly for controlled doming and smoothing during repoussé, while the ball peen end delivers focused strikes for texture. Follow the steps below to avoid common mistakes like over-striking or marring your metal.

Why a Chasing Hammer Works for Repoussé

The broad, slightly convex 25mm face of a chasing hammer spreads force over a wider area, which helps raise domes and smooth surfaces without creating sharp edges. This is essential in repoussé, where you push metal from the back to create a relief design. The ball peen end gives you a second option for adding texture or reaching tight spots.

A common trade-off: the bow face is less effective for deep, narrow indentations. For those, you would switch to a smaller repoussé hammer or a punch. The chasing hammer excels at broad shaping and evening out the metal surface.

Step-by-Step: Using a Chasing Hammer for Repoussé

1. Secure Your Workpiece: Place the metal sheet on a pitch bowl or a sandbag to support the back of the repoussé design. The pitch or sand absorbs the hammer blow and allows the metal to deform gradually. Check that the workpiece does not shift between strikes. If it moves, re-secure it or add more pitch.
2. Grip the Hammer Near the End of the Handle: Hold the wooden handle close to the butt end to maximize leverage and control. A choked-up grip reduces swing force and can cause uneven strikes. A loose, relaxed grip lets the hammer rebound naturally. Gripping too tightly leads to fatigue and less consistent blows.
3. Use the Bow Face for Broad Shaping: Angle the hammer so the convex face meets the metal flat, not on edge. Strike with a controlled, medium force. Let the weight of the hammer do the work rather than your arm. Striking at an angle can create unwanted dents or scratches. Keep the face parallel to the metal surface.
4. Switch to the Ball Peen for Texture or Detail: For stippling, texturing, or reaching into small depressions, rotate the hammer and use the ball peen end. Use lighter taps to avoid piercing thin metal. If the metal starts to work-harden (becomes stiff and resistant), anneal it before continuing.
5. Work Gradually Across the Design: Move systematically from the center outward or along the relief lines. Do not concentrate all strikes in one spot—spread the deformation evenly to avoid tearing. Stop and check the back of the metal after every few passes. A mirror or bright light helps you see low spots that need more work.
