Choose your materials: mild steel, wrought iron, or hardened steel

When making a nail header, you can choose from a variety of materials, including mild steel, wrought iron, or hardened steel. Each material has its own unique properties and is suitable for different types of nails.

Mild steel is a common choice for ordinary nails used in woodworking. It has a low carbon content, typically containing about 0.1% carbon, with the rest being iron and trace amounts of silicon or manganese. Mild steel nails are soft and easy to work with, making them suitable for general-purpose applications.

Wrought iron is another material that has been traditionally used for making nails and nail headers. It was commonly used before the 19th century and is still used for specific purposes, such as horseshoe nails. Wrought iron is known for its durability and strength, making it suitable for applications where soft cut nails are not adequate.

Hardened steel is often used for nails that require higher strength and durability. Nails made from hardened steel undergo a quenching and tempering process to increase their hardness. This type of nail is commonly used in construction and for specific purposes, such as masonry nails or drywall nails.

The choice of material depends on the intended use of the nails you plan to create. For general-purpose nails, mild steel is a suitable option due to its availability and ease of use. If you are creating nails for specific applications, such as construction or specialty nails, hardened steel may be a better choice to ensure durability and strength.

Additionally, consider the historical context and availability of materials. If you are creating nails in a colonial blacksmithing setting, for example, wrought iron may be a more appropriate choice as it was commonly used during that period. Similarly, if you are replicating 18th-century nail designs, you may opt for mild steel or wrought iron, as these materials were available at that time.

Cut your bar of iron to size: heat and use a hot cut or hardy tool

To make a nail header, you'll need to start by cutting your bar of iron to size. The first step is to heat your iron bar in a forge. Once it's hot enough, you can use either a hot cut or a hardy tool to cut it to the desired length.

A hot cut is a type of chisel that is designed to be used on hot metal. It's important to have a cut plate to work on when using a hot cut. If you're working solo, you can set the heated iron bar on the cut plate, but if you have an extra pair of hands, they can hold the bar while you work.

The hardy tool, on the other hand, is an anvil tool that fits into the square hardy hole and has a chisel edge. This tool is particularly useful when working with thicker bars of iron, as it provides more leverage and stability when cutting.

When using either the hot cut or the hardy tool, it's crucial to wear appropriate safety gear, including heat-resistant gloves and eye protection. The iron bar will be extremely hot, and there may be flying sparks during the cutting process.

Once your iron bar has been cut to size, you can move on to the next step of shaping it into a nail header. This involves hammering the bar flat and then using the edge of the anvil to define the shape of the tool. The face of the header will need to be made of steel to withstand repeated use. You can use scrap steel for this purpose, such as old files or wagon springs.

Shape the iron: hammer flat, define the tool head, and draw out the handle

Shaping the iron is a crucial step in creating a functional and durable nail header. Here is a detailed guide to help you through the process:

Hammer Flat: Start by obtaining a bar of salvaged wrought iron, preferably one with a square cross-section, similar to what was used in the 19th century. Heat the iron bar in a forge until it becomes malleable. Use a chisel or hardy tool to cut the bar to a length of about 6 inches. Now, hammer the bar flat, aiming for dimensions of approximately 1/2" x 1". This process removes any existing shapes or bends, creating a uniform base for the next steps.

Define the Tool Head: Place the flattened iron bar on the edge of your anvil. Using precise hammer strikes, start defining the head of the nail header tool. This step involves shaping the iron to create a distinct section that will eventually become the functional head of the tool. Ensure that you work the iron carefully to achieve the desired shape and size for the tool head.

Draw Out the Handle: Once the tool head is defined, it's time to focus on the handle. Using the anvil as a guide, continue hammering and drawing out the iron to form the handle. Imagine the handle as an extension of the tool head, gradually tapering away from it. This process involves both lengthening and thinning the iron to create a comfortable and functional handle. Remember that the handle should be long enough to provide a good grip and can be further refined later.

It is important to note that the nail header requires a steel face because the iron alone may not withstand repeated use. You can weld steel onto the face of the header, ensuring a tight fit without any overhang to prevent overheating and crumbling during welding. The steel adds durability and strength to the tool, making it capable of withstanding the forces of repeated nail-making.

By following these steps and paying attention to detail, you will be well on your way to shaping the iron for your nail header. Remember to take your time, work with the heated iron carefully, and always prioritize your safety when working with hot metals and forging tools.

Add steel to the face: cut and flux the steel, weld, and punch a hole

To make a nail header, you'll need to add steel to the face. Start by cutting and fluxing the steel. Cut your steel to fit the face of the header—you'll want to ensure there is no overhang, or the steel will overheat and crumble when you weld. For the flux, you can use fine sand, as was often used in early American smithing, or choose from a variety of modern fluxes.

Next, bring your iron up to an orange heat, slowly allowing the heat to sink in. Quickly apply the flux, place the steel, and bring the whole piece up to a welding heat. Repeat the weld a couple of times to seal any gaps.

Now you're ready to weld. Working with wrought iron and performing a forge weld require a very hot fire that will bring the metal to its melting point—around 2800°F. The top of the metal should be fluid, even goopy.

Finally, punch a hole in the header. You can start the hole from the back and finish it from the top. You can use a solid center punch, or, if you don't have one, any hardened steel with a point and a hammer. If you're making multiple nail headers, you might want to invest in a punch press or a Scotchman ironworker.

Finish and test: clean up the handle, heat and quench the header, and test with nails

Once you've made the nail header, you can use it to make nails. Start by heating the tip of your nail rod or drawn wire and hammering it out to a point. Then, use the edge of the anvil to create a shoulder on two sides of the nail. Clean up the taper of the nail on the anvil and draw it down so it slides smoothly into the header and rests on the shoulder. You can then notch the rod about 1/4" above the shoulder, ensuring it has a good heat, before breaking it off in the header.

Now you can focus on the finishing touches. Hammer down the head of the nail with four clean strikes on the four corners of the head. If you've followed the steps correctly, the nail should slip free of the header.

To heat treat and harden your nails, you'll need to heat a portion of the nail to a temperature higher than 1400° F (approximately 750° C). Then, quench, or rapidly cool, the nail by dipping or dropping it into a quenching fluid, such as tap water or process oil. The quenching fluid should be around 60-100° F (15-37° C). The nail will transform from a ferritic pearlitic structure to an austenitic structure, and then to a martensitic structure, which is harder and less ductile.

The process of making a nail header and using it to create nails is a traditional blacksmithing technique. It's a fun way to practice your hammer skills and create unique, handmade nails.
