Videos tagged with Cylinder Stop

This video discusses the potential mechanical challenges of modifying a Colt Python revolver to accept a seven-round cylinder, drawing parallels to the S&W 686 and Ruger GP100. The speaker hypothesizes that the Python's specific cylinder locking mechanism, which engages the cylinder stop and hand very late in the trigger pull, could be stressed by the increased cylinder diameter and rotation required for an additional round. This might lead to a less smooth trigger pull or increased wear on internal components, potentially explaining why Colt has historically opted for a six-round cylinder in the Python.

This video provides an expert-level breakdown of the Tranter 1879's unique dual cylinder stop and locking bolt system. The instructor, Othais, demonstrates how these mechanisms work in conjunction with the hand and recoil shield to ensure precise cylinder alignment and prevent over-rotation. The explanation highlights the differences compared to other historical revolvers like the Single Action Army, offering valuable insights for firearm enthusiasts and gunsmiths interested in historical firearm mechanisms.

This guide details the proper technique for opening and closing a revolver, as demonstrated by Jerry Miculek. Following these steps can prevent damage to the cylinder and frame, ensuring the longevity and timing of the firearm. Proper manipulation is key to maintaining firearms with high round counts.

This video provides an unboxing and overview of the Uberti reproduction Whitneyville Dragoon, highlighting its transitional features between the Colt Walker and later Dragoons. The presenter notes similarities to the Walker, such as the grip, back strap, trigger guard, and hammer spring, while also pointing out Dragoon-specific features like the cylinder length and oval stops. The video emphasizes the historical context of these design evolutions.

This video establishes a unified lexicon for revolver terminology, addressing the historical inconsistency in naming parts. The instructor, an apparent expert in firearms history and mechanics, meticulously defines components from basic actions (single/double) and frame types to intricate lockwork mechanisms like the 'dog', 'sprag', and 'transfer arm'. It also covers cylinder indexing, safety features, and loading/unloading systems, aiming to make revolver comparisons and discussions more consistent and understandable for enthusiasts.

This video provides a mechanical demonstration of Colt revolver timing mechanisms, contrasting them with Smith & Wesson and Ruger revolvers. The instructor explains that the perceived 'timing issues' on Colts are often a result of their design, where the cylinder stop engages later in the trigger pull, leading to a crisper break. This is presented as a characteristic difference rather than a universal flaw, with genuine timing issues being distinct from this design feature. The demonstration aims to correct misinformation and alleviate concerns about Colt revolvers' functionality.

This guide details the correct technique for closing a revolver cylinder, emphasizing the dangers of 'flicking' or slamming it shut. Improper closure can damage the pawl (cylinder stop), leading to misalignment and potential catastrophic failure. The video features an instructor with high authority, demonstrating proper handling and explaining the internal mechanics involved.

This video highlights an exception to a common revolver timing check method using a Swedish Lefaucheux revolver. The standard method of firing the hammer and holding the trigger to check cylinder lock-up fails on this specific firearm due to its design and conversion process. The cylinder rotates freely when the hammer falls, indicating a timing issue.

This video details a common timing issue in Colt New Army revolvers, highlighting the unique scalloped cylinder stops and the role of the hand and gate in achieving proper alignment. The instructor explains how to diagnose and address back-travel or inconsistent cylinder lock-up, often stemming from issues with the hand spring or the hand's engagement with the cylinder stops.

This video provides an in-depth breakdown of revolver mechanisms, moving beyond simple single vs. double action. It categorizes components by function: hammer, trigger, rotation, safety, and reloading. The presenter emphasizes the complexity often hidden within revolvers and explores various historical and modern designs, highlighting the ingenuity in their engineering. Understanding these functional groups is key to appreciating the nuances of revolver operation and design evolution.

This expert analysis, presented by TheYankeeMarshal, delves into the internal mechanisms of the new Colt Python revolvers to diagnose reported failures. The speaker, an experienced gunsmith and reviewer, identifies a redesigned 'hand' component, likely made from cast/MIM materials with a sharp, thin profile, as the root cause of cylinder rotation failures, especially when the firearm is short-stroked. The video compares new and old Python internals, highlighting improvements in other areas like the hammer stirrup and rebound lever, but concludes the hand's design and material are the critical weak points.

This video provides an in-depth look at the rare Sisterdale Texas Revolver, a unique Confederate sidearm. Ian McCollum details its historical context, production by German immigrants in Sisterdale, Texas, and its distinctive mechanical features, including a solid milled frame, external hand, and external cylinder stop. The revolver's rarity is emphasized, with only six believed to have been made and this example being the sole known survivor.
