Home Shop Rifling - Part 2

This video addresses a practical question regarding firearm maintenance and care: whether leaning a gun barrel can cause it to warp. The content aims to provide a definitive answer to this common concern among firearm owners. It delves into the physical properties of gun barrels and the forces they are subjected to during storage or handling, explaining the likelihood of such damage occurring from simple leaning. The video focuses on providing clear, evidence-based information rather than demonstrating specific firearm models or shooting techniques.

This guide explains how to adjust the trigger weight on a 1911 pistol, specifically addressing a viewer's request to increase a 3lb trigger to 5lbs. The process involves understanding that the 1911's trigger pull is governed by its leaf spring. Adjustments can be made by tuning the existing spring or by replacing it with a pre-tuned spring of the desired weight. The speaker, demonstrating experienced knowledge, emphasizes the importance of proper firearm handling and understanding the mechanism.

This content highlights the common misconception that drilling and tapping firearms for accessories like red dots or scopes is a simple DIY task. The hosts, with clear expertise signaled by their detailed discussion and industry affiliations (Springfield Armory hat), emphasize that the process is far more complex than often perceived. It requires specialized tools and a deep understanding of firearm mechanics to ensure safe and proper modifications, cautioning against amateur attempts.

This guide provides a detailed, step-by-step process for installing a TriggerTech trigger on a Remington 700 action, presented by an expert from Brownells. It covers trigger removal, installation of both single and two-stage models, and crucial post-installation safety checks. The video also touches on adjusting pull weight and the differences between TriggerTech's Primary, Special, and Diamond trigger grades.

The Yankee Marshal discusses the increasing difficulty in finding professional gunsmiths and highlights the specialized tools and expertise required for tasks like fitting a 1911 barrel or safety. While he performs much of his own firearm maintenance, he acknowledges that certain precision work necessitates professional gunsmithing, contrasting DIY methods with the requirements of professional metal smithing.

This guide details the process of 'sporterizing' a Swiss K31 rifle to improve its accuracy and modern usability. It covers essential gunsmithing techniques such as stock refinishing and advanced glass bedding to ensure a stable action-to-stock fit. The modifications are designed to be non-permanent, preserving the rifle's historical value while enhancing its performance with modern optics.

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.
