This video investigates the ballistic properties of tungsten carbide by comparing its performance against steel when fired from an FN 5.7 pistol. The description provides detailed information on tungsten carbide's composition, density, hardness, and industrial applications, including its use in armor-piercing rounds. The video aims to determine if tungsten carbide is truly bulletproof in this specific test scenario.
Larry Potterfield, founder and CEO of MidwayUSA, provides a detailed demonstration on how to polish small metal firearm parts. Using a variety of files and progressively finer grits of abrasive cloth, he meticulously works on parts from a Parker Brothers shotgun. This process, described as tedious but simple, prepares the metal for a beautiful blued finish. The video is presented as a GunTec Presentation and highlights the importance of surface preparation in gunsmithing.
This video tutorial, part of 'The Model 67 Project,' demonstrates the crucial steps involved in polishing a rifle barrel to achieve a superior surface finish for bluing. MidwayUSA CEO Larry Potterfield guides viewers through cleaning existing lettering, protecting it with tape, and progressively sanding the barrel from 120 grit up to 220 grit. The process involves both lengthwise sanding for scratch removal and cross-polishing for a smooth finish. A hobby lathe is used for the final sanding stages, and the protected lettering areas are polished once the tape is removed, leaving the barrel ready for the bluing process.
