Designing putters

Materials

The choice of material is crucial in putter design. Stainless steel is the most common material used in modern putters due to its durability and resistance to rust. It is harder than carbon steel and brass, allowing for more intricate designs and greater precision. Carbon steel was popular in the 90s and early 2000s but is more susceptible to rust, especially when the protective nickel plating is removed. Brass putters, though rare today, were common in vintage models but are softer and require careful handling during grinding and finishing processes. Other exotic materials like Damascus steel are also occasionally used in limited runs, offering unique aesthetics and performance characteristics.

Manufacturing Process

Putters can be manufactured through milling or casting processes. Milled putters are created from a single block of metal, typically stainless steel or carbon steel, using a CNC (Computer Numerical Control) milling machine. This method offers greater precision, intricate designs, and a softer feel but is more expensive. Casting, on the other hand, involves pouring molten metal into a mold, providing more versatility in shapes and designs at a lower cost. Cast putters may have a slightly firmer feel compared to milled ones.

Design and Customization

The design of the putter focuses on creating the perfect "sweet spot" for striking the ball cleanly. The hosel, where the club shaft is mounted, plays a crucial role in defining the center of gravity and how the club feels in the golfer's hand. Customization is a key aspect, with companies like CMBD creating putters tailored to individual golfers' natural putting strokes and preferences. 3D printing and CAD (Computer-Aided Design) technologies are often employed to create physical models and fine-tune dimensions, connections, and balance before the final production.

Finishing and Assembly

After the initial manufacturing, putters may undergo additional processes like polishing, finishing, and engraving to enhance their appearance and feel. Assembly involves cutting the putter to the desired length, adjusting the loft and lie, and gripping. These steps contribute to the overall performance and feel of the putter, ensuring it aligns with the golfer's natural stroke and provides the desired feedback on putts.

Materials used

Golf putters are typically made from metal, with the most common material being stainless steel. Stainless steel is harder than carbon steel and brass, and it is also generally non-magnetic and resistant to rust. Carbon steel was a common material for putters in the 1990s and early 2000s, but it is very prone to rust. Brass is the least common material for modern putters due to its softness and lack of receptiveness to chemical finishes.

Some putters are made from exotic materials such as Damascus steel, copper, or manganese bronze, a mixture of manganese, zinc, copper, aluminium, and iron. The choice of material depends on the desired feel and performance of the putter, as well as cost considerations.

Milled putters are created from a single block of metal, usually stainless steel or a soft metal like carbon steel. The putter head is carved out using a CNC (Computer Numerical Control) milling machine, which shaves the metal into the desired shape with high precision. This process allows for intricate designs, greater precision, and a softer feel but at a higher cost.

Cast putters, on the other hand, are made by pouring molten metal into a mould of the desired shape. This method is more versatile and affordable, but the putter may have a slightly firmer feel. Low-volume casting is typically cheaper, at between $200-$400 per head.

The manufacturing process can significantly influence the feel, performance, and cost of a putter. Milled putters often feature distinct, precise lines and a more refined finish, while cast putters can produce a wider variety of shapes and designs.

Manufacturing processes

Manufacturing a golf putter involves several processes, each influencing the putter's feel, performance, and cost. The two primary methods for making putters are milling and casting.

Milled putters are created from a single block of metal, usually stainless steel or softer metals like carbon steel. The putter head is carved using a CNC (Computer Numerical Control) milling machine, which shaves the metal with high precision to achieve the desired shape and intricate design patterns. The milling process can be expensive and typically involves multiple steps, with the number of steps depending on the desired level of finish. The first step involves milling the back profile of the putter body and neck, followed by milling the front of the putter, including the front profile of the neck and the loft.

Milled putters offer greater design intricacy, higher precision, and a softer feel at impact. They often feature distinct, precise lines and a refined finish, appealing to golfers who value craftsmanship and aesthetics. The milling process allows for precise control over the design, resulting in a more consistent feel across the putter face.

On the other hand, cast putters are made by pouring molten metal into a mold of the desired shape. Once the metal cools and solidifies, it is removed from the mold and may undergo additional processes like polishing and finishing to enhance its appearance and feel. Casting offers versatility in creating a wider variety of shapes and designs, including intricate cavity backs or larger mallets, at a more affordable price point. However, cast putters may have a slightly firmer feel at impact compared to milled putters.

The choice between milled and cast putters depends on the golfer's preference for feel, performance, appearance, and price. The manufacturing process also involves creating a positive model of the design, which can be done through 3D printing and handwork. This physical model is then taken to a casting shop, where it is transferred into a casting mold or a positive wax model for the final production.

Finishing touches

The finishing touches of a golf putter refer to the final steps in the manufacturing process, which can include polishing, engraving, and other customisations. The specific finishing processes will depend on the materials used and the desired look and feel of the putter.

For example, cast putters are often polished and finished to enhance their appearance and feel. This can include removing nicks and dings with a deburring wheel, which requires careful attention to avoid altering the shape of the putter, especially if the putter is made of a softer metal like brass.

Milled putters, on the other hand, are known for their distinct, precise lines and refined finish. The milling process allows for greater detail and customisation, resulting in a premium product. However, this level of customisation comes at a higher cost.

In terms of materials, stainless steel is the most common in the modern-day putter industry due to its hardness and resistance to rust. Other materials such as carbon steel and brass are also used, but they may require additional finishing processes, such as nickel plating to prevent rust.

Finally, some putters may undergo additional customisations such as engraving the maker's mark or logo. This is often done with an endmill, a type of milling cutter, to create a precise and refined finish.
