Mark Serbu demonstrates the flame hardening process for the ejection port edge of a BFGA receiver. This technique uses an oxy-acetylene torch to heat the steel to its austenitization temperature, followed by rapid quenching in water. The purpose is to harden the edge, preventing it from bending or dinging when large caliber casings are ejected, thereby increasing the receiver's durability.

This guide details the advanced gunsmithing process of creating new leaf springs for British side-by-side shotguns, as demonstrated by English-trained gunsmith Jack Rowe. The process involves shaping spring steel bar stock, heat treating, hardening, and tempering to achieve the correct tension and elasticity. This technique is crucial as replacement springs are often unavailable.

This video demonstrates the process of making and hardening a small spring, likely for firearm repair or fabrication. It covers crucial steps like shaping, heat treatment to achieve a uniform red color, oil quenching, and testing the spring's temper and set. The instructor emphasizes the importance of not overheating the spring and the benefits of making it slightly too soft for re-hardening, rather than too hard which risks breakage.
