This video features Roy showcasing his new milling machine. The description links to LittleMachineShop.com, suggesting a focus on metalworking tools and equipment used in machining and fabrication, potentially for hobbyists or professionals. While the title itself doesn't directly mention firearms, the context of milling machines often aligns with gunsmithing and custom firearm builds.

This video documents Roy's process of upgrading his milling machine. The title "Out with the old, in the with new" suggests a replacement or significant improvement of existing equipment, implying a focus on machinery used in fabrication or modification. While the title doesn't explicitly mention firearms, the context of "upgrading" machinery often aligns with the hobby of gunsmithing or custom firearm building, where precise machining is crucial. The description is empty, leaving the title as the sole indicator of content.

This video demonstrates how to apply bluing to carbon steel tools for rust resistance. It covers essential preparation steps like removing existing rust with a wire wheel and degreasing with brake cleaner. The application involves using Birchwood Casey Super Blue, followed by rinsing, drying, and oiling for optimal protection.

This YouTube video focuses on a versatile Grizzly vise with lift, highlighting its utility and the idea that one can never have too many vises. While the title and description don't explicitly mention firearms, vises are common tools in gunsmithing and firearm maintenance. Therefore, tags are derived from the potential applications of such a tool within the firearms community.

This video offers a behind-the-scenes look at the various machines present in Dragonman's workshop, with the creator sharing insights into their uses. With an impressive 58 years of experience in the field, the video aims to demystify the equipment that supports his work. A link to Dragonman's merchandise store is also provided.

This YouTube video focuses on the process of surface grinding a hammer. While the description is brief, the title clearly indicates a hands-on approach to modifying or preparing a hammer, likely for a specific application that requires a flat or precisely surfaced working end. This could be relevant for gunsmithing, tool modification, or general metalworking.

Mark Serbu details the complex process of converting a CNC lathe into a 12-barrel blank-firing machine gun. The project highlights the critical role of a lathe's C Axis for precise rotational control and the application of PID control theory to overcome initial firing failures. Modifications were made to ensure the device fires blanks only, avoiding legal issues.

This video demonstrates how to rifle a barrel in a home shop using basic tools, bypassing expensive CNC equipment. It covers material preparation, precise drilling and reaming, and the critical process of pushing a rifling button. While a DIY approach is shown to be possible, the video highlights the significant difference in quality and precision achievable with professional CNC machining.

This video provides an in-depth analysis of the Serbu RN-50 rifle that experienced a catastrophic failure during a Kentucky Ballistics test. Mark Serbu, the designer, meticulously examines the damage, noting severely bent steel side plates, sheared-off breech cap ears, and a sheared pivot pin. The inspection also covers the breech cap's condition, barrel threads, and the stuck casing, revealing a case head separation.

Mark Serbu, designer of the RN-50, addresses a catastrophic failure experienced by Kentucky Ballistics. He reassures customers about the RN-50's safety, attributing the incident to counterfeit or over-pressured ammunition. Serbu highlights the rarity of such events and emphasizes industry transparency, noting that his company has produced approximately 1,400 RN-50s since 2016 with hundreds of thousands of rounds fired without issue.
