This video explains the process of flame hardening, a heat treatment technique for steel. It emphasizes that the steel must be heat-treatable, specifically carbon or alloy steel with at least 0.2% carbon content. The process involves locally heating an area of the steel to achieve hardening.
This video review focuses on the newly revealed Ruger-made Marlin Model 1895 SBL shotgun. It highlights significant manufacturing improvements implemented by Ruger, including more precise chambering, wire EDM machining for critical parts like the sear notches, and advanced heat-treating techniques for receivers. The review also praises the tight metalwork fit and finish, elegant laminate stocks with improved checkering, and overall aesthetic upgrades that return the rifle to its roots while enhancing performance and reliability. The video emphasizes Ruger's impact on the Marlin brand.
This video focuses on welding and heat treating, directly appealing to individuals involved in these specific metalworking processes. The creator explicitly states that the content will be uninteresting to those not engaged in these fields, highlighting a niche technical focus. While no firearms are explicitly mentioned, the processes described are commonly associated with firearm manufacturing, customization, or repair. Therefore, the tags lean towards the technical aspects that would be relevant to someone interested in these areas within the firearms community.
This video, Part 2 of a home shop rifling series, explains the critical importance of heat treating a barrel *before* rifling. The creator details how the necessary hardness (Rc 28-32 for 4140/4150 steel) impacts the rifling process, requiring more force to swage the rifling but ultimately resulting in a stronger, tougher barrel. Key reasons for pre-heat treatment include preventing the rifling button from picking up steel and preserving the precise bore dimensions and straightness during the high-temperature heat treating and quenching process. Post-rifling heat treatment would compromise the strain-hardened bore surface, which significantly reduces friction and enhances wear resistance.
This video review from Fun Gun & Gear Reviews showcases the BlackHeart Knives 'Gunner 12' custom knife. The description highlights its status as a "beautiful masterpiece" handcrafted by Rich Robinson, emphasizing the extensive heat treating and tempering processes (over 30 hours) applied to each blade to ensure durability and performance in any situation. The review aims to provide an in-depth look at this custom knife.
This video demonstrates the process of annealing metal parts for gunsmithing applications. Larry Potterfield, CEO and Founder of MidwayUSA, explains and shows how to soften hardened gun components, which is a crucial step before shaping and polishing them. The annealing process is presented as a preparatory method for subsequent color case hardening of firearm parts. Viewers are encouraged to visit the MidwayUSA Video Library for more content.
