This video details the process of repairing a chopped receiver section from a Star Z70 parts kit. Mark Serbu, a gun designer, demonstrates how to fabricate and weld in replacement metal to restore the structural integrity and form of the receiver. He emphasizes using an expanding mandrel for alignment and copper flashing to protect against welding spatter, while also discussing techniques to minimize heat distortion and achieve a functional repair using 'caveman tools' and optional CNC machining.

This video details a failed attempt at stamping a firearm component using a 120-ton hydraulic press. Mark Serbu, owner of Serbu Firearms, highlights the critical importance of precise material alignment and die design in sheet metal stamping. The demonstration showcases common pitfalls, such as misalignment leading to skewed parts, and the challenges of achieving complex bends with simple dies. Serbu emphasizes that learning from failures is integral to the engineering process.

This video demonstrates a gunsmithing technique for repairing a damaged or incorrectly machined extractor slot using TIG welding. The instructor emphasizes building up the material higher than needed and then reshaping it through machining or filing. The process highlights the flexibility of welding for correcting errors in firearm components.

This video demonstrates a basic TIG welding technique for filling a groove, drawing parallels to gas welding. The instructor emphasizes using an electric arc and a feed rod, comparing the TIG torch to a gas torch. The process involves initial filling, inspection, and optional finishing with a smaller rod, followed by material removal with a grinder. The instructor prefers golfing gloves for better feel during welding.

This video provides an expert-level unboxing and initial assessment of a Dake 150-ton Hydraulic Press, highlighting its USA manufacturing and robust capacity. The speaker, demonstrating high authority in shop tools and fabrication, emphasizes the importance of quality equipment for professional environments. Key features like the 150-ton gauge and 'Made in USA' origin are showcased.

This video demonstrates the construction and firing of an improvised explosive device, locally dubbed the 'Ukrainian Baseball Bat.' It combines an RPG rocket motor with an 82mm mortar round, creating a shoulder-launched munition. The process involves adapting an RPG warhead for FPV drone use, repurposing the rocket motor, and attaching it to a mortar round via a custom-made adapter fabricated in a local metal shop.

This video provides an in-depth review and comparison of a budget TIG welder (Yes Welder) against a professional-grade machine (Miller Syncrowave 200). The presenter, a gun designer with 25 years of welding experience, details the unboxing, setup, and performance of the Yes Welder, highlighting its limitations such as a non-variable pedal and lack of pre/post-flow. He demonstrates various welding techniques on different materials, comparing the results to the Miller, and offers insights into essential TIG welding features.

Mark Serbu demonstrates the process of designing and fabricating sheet metal dies to stamp firearm components, inspired by the WWII-era Sturmgever. He details the challenges of die creation, including machining and heat treatment, and showcases the successful stamping of a component using a 200-ton hydraulic press. The video highlights the potential for efficient manufacturing through stamping compared to traditional CNC machining of aluminum.

This video demonstrates a technique for precisely welding rectangular tubing using a makeshift internal fixture and copper flashing as a backing material. The instructor emphasizes thorough preparation, including cleaning and alignment, to achieve strong, flush welds. The use of copper flashing prevents weld sticking and burn-through, while the internal fixture maintains structural integrity during the welding process. The guide offers practical tips for managing weld imperfections and achieving a professional finish.

This video details the process of fabricating custom steel knockdown targets. Autumn, with guidance, uses a bandsaw and angle grinder to cut and shape steel plates into silhouette targets. The process includes essential steps like using coolant for cutting, grinding down sharp edges, and finally, welding the targets to their bases. The video highlights Autumn's progression in welding, demonstrating the creation of durable, custom shooting targets.

This video's title and description suggest a focus on metalworking techniques, specifically involving a hammer and polishing. The mention of "push it back where it belongs before you break out the dremel tool" and "polish your hammer faces" strongly implies a process related to shaping or repairing metal, possibly in the context of metal fabrication or repair. While no specific firearms are mentioned, the language might allude to maintenance or customization of firearm components, or it could be a metaphorical approach to a gunsmithing task.

This guide details how to repurpose wire coat hangers into essential survival tools, drawing on the practical, instructional, and resourceful expertise of SensiblePrepper. Learn to fabricate survival needles, secure gear with custom keepers and safety pins, create cooking utensils, and even build stove components. The video emphasizes the versatility of wire hangers as a readily available resource for various SHTF scenarios.
