How to Forge a Ball Peen Hammer: A Step-by-Step Guide

Have you ever considered forging your own ball peen hammer? It’s not only a rewarding project but also a fantastic way to add a personalized touch to your blacksmithing toolkit.

In this guide, we’ll walk you through the process of forging your own ball peen hammer, from selecting the right materials to putting the finishing touches on your custom creation.

Let’s get started!

Materials and Tools You’ll Need

Before you begin, you’ll need to gather the necessary materials and tools for forging your ball peen hammer:

  • Hammerhead material: Choose a high-quality steel, such as 4140, 1045, or H13. Refer to our guide on the 3 best steels for making hammers to learn more about your options.
  • Hammer handle: A piece of hickory or ash is ideal for crafting a sturdy, shock-absorbing handle.
  • Forge or propane torch
  • Anvil or striking surface
  • Tongs or vise
  • Drift or punch
  • Files and/or angle grinder
  • Sandpaper or wire brush
  • Safety gear: Gloves, eye protection, and proper clothing

Forging the Hammerhead

Step 1: Heating and Shaping

Heat your steel in the forge or with a propane torch until it reaches forging temperature (around 2,100°F or 1,150°C for most steels).

Once heated, use tongs to hold the steel or secure it in a vise, and begin shaping the hammerhead using a rounding or cross-peen hammer. Shape the flat face of the hammerhead first, followed by the ball peen.

Step 2: Punching the Eye

Once you’ve shaped the hammerhead, mark the location for the eye (the hole for the handle) and use a punch or drift to create the hole. Be sure to punch from both sides to avoid uneven or off-center eyes.

Step 3: Refining and Shaping

After punching the eye, refine the shape of the hammerhead using files or an angle grinder. This is your chance to ensure the faces are smooth and even, and the eye is the correct size for your handle.

Finishing the Hammerhead

Step 4: Heat Treating

Heat treat your hammerhead to increase its hardness and durability. This typically involves heating it to a specific temperature (varies depending on the steel) and quenching it in oil or water, followed by tempering in an oven or forge at a lower temperature.

Step 5: Cleaning and Polishing

Clean the hammerhead using a wire brush or sandpaper to remove any scale or residue from the forging and heat treating process. You can also polish the faces and peen to your desired finish.

Crafting and Installing the Handle

Step 6: Shaping the Handle

Shape your handle using a rasp, drawknife, or other woodworking tools, ensuring it fits comfortably in your hand and has the proper tenon size to fit the eye of your hammerhead.

Check out our guide on custom hammer handles for more tips on crafting the perfect handle.

Step 7: Installing the Handle

Insert the handle into the eye of the hammerhead, making sure it fits snugly. If necessary, use a wooden or metal wedge to secure the handle in place.

Step 8: Finishing Touches

Apply a wood finish or linseed oil to your handle to protect it and prolong its life. Now you have a beautiful, custom-forged ball peen hammer ready for use in your blacksmithing or bladesmithing projects!

Maintaining Your Custom Ball Peen Hammer

To ensure the longevity of your newly forged ball peen hammer, follow these maintenance tips:

Cleaning: Keep your hammer clean by wiping off any debris, dust, or dirt after each use. If needed, use a wire brush to remove any stubborn buildup.

Proper Storage: Store your ball peen hammer in a dry, cool area to prevent rust and corrosion. Hanging it on a tool rack or placing it in a toolbox can help protect the hammer from damage.

Handle Inspection: Regularly inspect the handle for any signs of wear, cracks, or loosening.

If necessary, refer to our guide on how to replace a ball peen hammer handle for a step-by-step process on replacing a worn handle.

Common Uses for Your Forged Ball Peen Hammer

Now that you’ve crafted your very own ball peen hammer, it’s time to put it to work!

Here are some common blacksmithing and bladesmithing tasks that can be accomplished with a ball peen hammer:

Riveting: The ball end of the hammer is perfect for rounding and forming rivets, which can be used to join metal pieces together.

Metal Shaping: Use the flat face of the hammer to shape and flatten metal, or the ball end to create curves and indentations.

Texturing: The ball peen can be used to add texture to your metalwork, creating unique patterns and finishes.

Chasing: With the proper chisel, the ball peen hammer can be used for chasing, a technique used to create detailed designs and patterns in metal.
