Over 25 years of experience in custom brass casting informs the production of personalized amateur radio call sign belt buckles. These solid brass buckles are crafted using traditional sand casting methods, ensuring a unique, durable product for radio operators. Each piece is hand-poured and polished in Washington State, reflecting a commitment to quality craftsmanship. The manufacturing process begins with a customer's idea, which is then translated into a graphic proposal. Upon approval, patterns are created for the custom edition. An antique foundry press compresses specially formulated sand around these patterns, followed by hand-pouring molten brass into the molds. After cooling, the castings are sandblasted, inspected, and meticulously polished by skilled craftsmen. Northwest Brass Works provides a lifetime guarantee on the buckle hardware, offering repair or replacement for any breakage. They also offer guidance on maintaining the polished luster of the brass using products like _Nevr-Dull_, ensuring the buckle's longevity and appearance for many years of wear.
