Choosing the Right Diameter & Wall Thickness

Selecting the diameter depends entirely on the size and intended use of the handle. For heavy-duty tools like a hatchet or a digging spade, an outer diameter of 1/4 inch is standard for structural security. Smaller cutlery or detail knives can comfortably use 1/8 inch or even 3/32 inch tubing.

Wall thickness determines how the pin handles force. A thicker wall prevents the pin from collapsing during the peening process, which is essential when the brass must expand to fill a counter-bored hole. Always account for the density of the handle material; harder woods like hickory or locust require more durable, thicker-walled pins to withstand the expansion pressure.

• Small diameter (1/16″ – 3/32″): Best for detail, delicate scales, and lightweight folding tools.
• Medium diameter (1/8″ – 5/32″): The sweet spot for most fixed-blade knives and smaller garden tools.
• Large diameter (3/16″ and up): Necessary for structural handle pins on heavy-impact equipment.

How to Cut and Finish Your Brass Pin Stock

Precision starts with the cut. Use a fine-toothed jeweler’s saw or a high-quality tubing cutter to ensure the ends remain square and free of burrs. A square end ensures that when the pin is pressed through, it makes even contact with the opposite scale, resulting in a cleaner look and a stronger mechanical lock.

Once cut, deburr the inside and outside of the tube using a small round file or a reamer. This prevents the tube from splintering the handle material during insertion and makes the final peening process much smoother. Always leave about 1/16 inch of excess material protruding on both sides to allow for a proper “head” when hammering.

• Peening: Use a ball-peen hammer with light, deliberate strikes, working from the center outward.
• Finishing: Once set, sand the pin flush with the handle using progressive grit levels, starting at 220 and moving up to 600 or higher for a polished look.

Brass Alloys Explained: Which Type Is Best?

Not all brass is created equal, and the alloy composition dictates how it performs under pressure. C260, commonly known as yellow brass or cartridge brass, is the industry standard for its combination of strength and workability. It is durable enough to hold a handle together but soft enough to be manipulated without cracking.

Avoid unknown “mystery brass” found in generic scrap bins if structural integrity is required. Impure alloys can be brittle, leading to pins that snap during the peening phase or corrode prematurely when exposed to the acidic juices of harvested crops or salty fertilizers. Sticking to recognized alloys like C260 or C360 ensures predictable behavior every time.

• C260 (Cartridge Brass): High ductility, excellent for peening and cold-working.
• C360 (Free-Machining Brass): Contains lead for easy cutting and drilling, but can be slightly more brittle during aggressive peening.

Choosing the right brass tubing transforms a simple repair into a permanent improvement. By matching the alloy and dimensions to the tool’s specific demands, the result is equipment that remains functional and safe for years of seasonal cycles. Stick to these standards, and your shop will remain a place of reliable production rather than constant rework.
