Preparing for the Forge
Safety First
Safety should always be your top priority when blacksmithing. Proper ventilation is crucial when working with a forge, as the process produces harmful fumes. Always wear appropriate safety gear including:
- Heat-resistant gloves
- Eye protection with side shields
- Closed-toe leather boots
- Natural fiber clothing (cotton or wool)
- Respirator (especially when grinding)
- Ear protection
- Leather apron
Setting Up Your Workspace
Organize your workspace efficiently with all tools within easy reach. Your anvil should be secured at the proper height (knuckle height when standing with arms at your side) and positioned close to your forge. Have a quenching tank ready and filled with your chosen quenching medium.
The Forging Process: Step by Step
Step 1: Selecting and Preparing the Steel
Choose the right steel for your axe. High-carbon steels like 1045, 1075, or 5160 are excellent choices. You’ll need a substantial piece approximately 2-3 inches wide, 4-6 inches long, and about 3/4 inch thick, depending on your desired axe size.
Step 2: Heating the Steel
- Heat your forge to around 1900°F (1040°C).
- Place your steel stock in the forge.
- Heat until it reaches a bright orange-yellow color (approximately 1200°C).
- Move the steel frequently to ensure even heating.
Step 3: Initial Shaping
Begin by creating the basic shape of your axe:
- Remove the hot steel from the forge using tongs.
- Place it on the anvil and begin hammering to create the rough axe shape.
- Focus on flattening and extending what will become the blade.
- Work quickly while the metal is hot, reheating as necessary.
- Use the cross peen hammer to spread the steel for the blade.
Step 4: Creating the Eye
The eye is one of the most challenging aspects of forging an axe. There are several methods to create it:
Method 1: Punching and Drifting
- Heat the steel to a bright orange-yellow.
- Use a punch to create a starter hole.
- Gradually enlarge the hole using progressively larger drifts.
- Work the eye to the desired shape and size.
Method 2: Folding/Wrapping Method
- Flatten your stock into a rectangular shape.
- Create a fold in the middle.
- Forge weld the sides while leaving the eye open.
- Shape using a drift.
Step 5: Shaping the Blade and Poll
- Once the eye is formed, focus on refining the blade.
- Draw out the steel toward the bit, creating a tapered edge.
- Use controlled hammer blows to thin and widen the blade.
- Shape the poll (back) of the axe for balance and function.
- Use the horn of the anvil to shape the cheeks of the axe.
Step 6: Refining the Form
During this stage, focus on the final shaping of the axe using techniques like cross peening and fullering to move and manipulate the material to its intended location. Take your time to achieve the proper proportions and balance.
Heat Treating Your Axe
Heat treating is crucial for ensuring your axe performs well and lasts a long time. This process involves hardening and tempering.
Step 1: Normalizing the Steel
Normalizing is a technique used to homogenize the grain size within the steel, enhancing its overall strength and toughness. This process encourages grain refinement, improving the material’s durability.
- Heat the axe head to a bright orange-red color (about 1550°F/843°C).
- Remove from the forge and allow it to cool completely in still air.
- Repeat this process 2-3 times to refine the grain structure.
Step 2: Hardening
Hardening involves heating the axe head to a very high temperature and then cooling it off quickly and evenly. This creates a very hard but brittle structure.
- Heat the entire axe head to critical temperature (non-magnetic, bright orange/red).
- Prepare your quenching medium (oil is generally preferred for axes).
- Quickly submerge the edge of the axe in the quenching medium.
- Move the axe continuously in the quenching medium to ensure even cooling.
Step 3: Tempering
Tempering reduces the brittleness of the steel by heating it slowly to a lower temperature and then letting it “bake” before cooling down naturally.
- Clean the axe head to bare metal so you can observe tempering colors.
- Heat the axe in an oven to approximately 400-450°F (204-232°C).
- Maintain this temperature for 1-2 hours.
- Let the axe cool slowly in still air.
Tempering Temperature Guide
| Temperature | Result | Ideal For |
|---|---|---|
| 350-400°F | Very hard, somewhat brittle | Fine cutting tools |
| 400-450°F | Good hardness, better toughness | Axes, hatchets |
| 450-500°F | Moderate hardness, good toughness | Heavy-use tools |
| 500-550°F | Lower hardness, excellent toughness | Striking tools |
At around 450 degrees, your axe will have a Rockwell hardness of 56 to 58, which is ideal for maintaining an edge while being tough enough to withstand impact.
Finishing Your Axe
Step 1: Grinding and Sharpening
- Use a belt grinder or files to establish the basic edge geometry.
- Start with coarse grits (36-60) and progress to finer grits.
- Create a primary bevel of about 20-25 degrees.
- Refine the edge with progressively finer abrasives.
- Finish with a strop for a razor-sharp edge.
Step 2: Handle Fitting (Hafting)
A properly hafted axe will be both secure and usable. Traditional hafting methods involve using hand tools like a shave horse to shape and fit the handle precisely to the eye of the axe.
- Select a high-quality hardwood handle, preferably hickory.
- Shape the handle end to fit the eye snugly.
- Insert the handle, ensuring proper alignment.
- Secure with wooden or metal wedges.
- Trim any excess material flush with the head.
Step 3: Final Finishing
- Clean the entire axe head of any scale or debris.
- Apply a protective finish to the metal (oil, wax, or a rust preventative).
- Treat the handle with linseed oil, tung oil, or another suitable finish.
- Add any decorative elements if desired.
Axe Maintenance and Care
To keep your hand-forged axe in excellent condition:
- Clean and dry the axe after each use.
- Store in a dry location, with a light coat of oil on the metal.
- Sharpen regularly with a file or stone.
- Check the handle for cracks or looseness periodically.
- Re-oil the handle occasionally to prevent drying and cracking.
Common Problems and Solutions
| Problem | Possible Cause | Solution |
|---|---|---|
| Warping during quenching | Uneven heating or cooling | Normalize again and re-quench more carefully |
| Cracking during quenching | Too rapid cooling, sharp edges | Round edges before quenching, use milder quenchant |
| Soft edge | Insufficient hardening | Reharden with proper temperature |
| Too brittle | Insufficient tempering | Temper at a higher temperature |
| Eye deformation | Improper drifting technique | Redrift carefully or start over |
| Handle loosening | Improper fit or wood shrinkage | Replace wedges or handle |
Frequently Asked Questions
What is the best steel for forging an axe?
High-carbon steels with 0.5-0.8% carbon content are ideal for axes. Common choices include 1045, 1075, 5160 spring steel, and tool steels. Many blacksmiths also use reclaimed leaf springs from vehicles, which are typically made from 5160 steel.
How long does it take to forge an axe?
Forging an axe does not take too much time. You can form a complete axe head within a day as long as all factors are favorable. However, for beginners, it may take several days, including the time for heat treatment and handle fitting.
Do I need to forge weld a hardened edge to my axe?
Traditional axes often had a high-carbon steel bit forge welded to a milder steel body. While this is still practiced by some smiths, you can also forge an excellent axe from a single piece of properly chosen steel. The decision depends on your materials, skill level, and desired outcome.
What’s the proper temperature for forging steel for an axe?
The best forging temperature for steel is around 1200°C (2200°F). The flame for forging steel should be yellowish-red. Experienced blacksmiths can judge the temperature by the color of the steel.
How do I test if my axe is properly hardened?
After hardening but before tempering, test the edge with a file. The file should skate across the surface without biting into it. After tempering, the file should bite slightly, indicating the proper balance of hardness and toughness.
