DIY Garden Pruning Shears: A Comprehensive Guide18

Pruning shears are an essential tool for any gardener, whether you're tending a small herb garden or a sprawling orchard. However, high-quality pruning shears can be surprisingly expensive. This comprehensive guide will walk you through the process of crafting your own pair of garden pruning shears from readily available materials. While this project requires some basic metalworking skills and tools, the satisfaction of creating a functional and personalized tool is immeasurable.

I. Materials and Tools

Before you begin, gather the necessary materials and tools. The quality of your finished shears will depend heavily on the materials you choose. Cheap or brittle materials will result in shears that are prone to breakage and won't provide a clean cut.

Materials:
Two pieces of high-carbon steel: Approximately 6-8 inches long and ½ inch wide. High-carbon steel is crucial for sharpness and durability. You can source this from a metal supplier, hardware store, or even repurpose suitable steel from old tools (ensure it's high-carbon steel for optimal results). The exact dimensions will depend on your desired shear size.
Rivets: These will secure the two blades together. Choose rivets made of a strong metal like steel or brass, slightly larger than the thickness of your steel blades. The number of rivets will depend on the length of your blades – at least two are recommended.
Handles: You have several options for handles: hardwood (like ash or hickory), strong plastic, or even repurposed materials like sturdy sections of metal pipe. The handles should be comfortable to grip and approximately 4-6 inches long.
Bolts and nuts (optional): If using wooden handles, bolts and nuts can provide additional securement to the blades.
Epoxy or strong adhesive: To securely attach the handles to the blades.

Tools:
Angle grinder with cutting and grinding wheels: Essential for shaping the blades and handles.
Files (various grits): For refining the shape and sharpening the blades.
Drill press with appropriate drill bits: For drilling holes for the rivets and bolts (if using).
Hammer: For setting the rivets.
Anvil or hard surface: For shaping the metal.
Vice grips or clamps: To hold the metal securely during shaping and drilling.
Safety glasses and gloves: Absolutely crucial for protecting yourself from sparks and sharp edges.
Sharpening stone or honing steel: To sharpen the blades after shaping.

II. Constructing the Shears

Step 1: Shaping the Blades:

Using the angle grinder, carefully cut the steel into two roughly equal pieces. Then, use the grinder to shape the blades, ensuring one blade is slightly concave and the other convex. This creates the cutting action. Take your time and use the grinder with controlled movements to avoid mistakes. Refer to existing pruning shear designs for guidance on the optimal blade shape. Once roughly shaped, use files to refine the edges and create a smooth transition between the cutting surfaces.

Step 2: Drilling the Rivet Holes:

Carefully mark and drill pilot holes for the rivets in both blades. Ensure the holes are aligned perfectly to allow for smooth articulation. Use a drill press for accuracy.

Step 3: Attaching the Handles:

Shape the handles according to your preference. If using wood, sand them smooth. Drill holes in the handles to align with the rivet holes in the blades. Secure the blades to the handles using the rivets and a hammer, ensuring a tight fit. Alternatively, if using bolts and nuts with wooden handles, use appropriate sized drill bits to fit these securely into place.

Step 4: Sharpening the Blades:

This is a critical step. Use a sharpening stone or honing steel to carefully sharpen the blades. Maintain a consistent angle to create a sharp, clean cutting edge. Test the sharpness on a piece of soft wood. The blades should cut through easily without needing excessive force.

Step 5: Finishing Touches:

Once the blades are sharp, sand any rough edges on the handles and blades for comfort and safety. Apply a protective coating to the metal parts to prevent rust and corrosion. A clear coat of varnish or paint is recommended for wooden handles.

III. Safety Precautions

Working with metal and sharp tools presents inherent risks. Always prioritize safety:
Wear safety glasses and gloves at all times.
Use the angle grinder and other power tools with caution and proper technique.
Ensure the work area is well-lit and ventilated.
Take breaks to avoid fatigue, which can lead to mistakes.
Dispose of metal shavings and debris responsibly.

IV. Conclusion

Creating your own pruning shears is a rewarding project that combines craftsmanship with practical gardening. While it requires some skill and patience, the resulting tool is a testament to your efforts and a valuable addition to your gardening arsenal. Remember to always prioritize safety and take your time with each step. With careful attention to detail, you'll have a pair of custom-made pruning shears that will serve you well for years to come.
