This video explains the cause of discoloration on the muzzle of a custom .38 Special Long Slide 1911, previously owned by James Earl Jones. The discoloration is a direct result of the gunsmithing technique used by Jim Clark Senior, who invented the long slide 1911. Clark would modify standard slides by cutting and welding sections, a process that alters the steel's properties and consequently affects the bluing process, leading to visible color differences at the weld point.

This video reveals secrets to achieving a professional cold blue finish, overcoming common splotchy results. It highlights Brownells Oxpho-Blue Creme as superior to liquids and emphasizes proper degreasing with 91% isopropyl alcohol or acetone, followed by heating the metal. The process involves applying the creme, buffing with 0000 steel wool, and repeating for a deep blue-black finish.

This expert guide from Brownells' 'Smyth Busters' series clarifies the significant differences between cold and hot bluing for firearms. Hot bluing, a high-temperature process creating a durable black oxide layer, is presented as superior for overall finish and longevity. Cold bluing, a lower-temperature chemical reaction, is deemed less durable and best suited for minor cosmetic touch-ups on scratches and nicks, not for rebluing an entire firearm.

This video demonstrates the traditional slow rust bluing process for firearms, emphasizing its durability and satin finish suitable for high-end rifles. Key steps include meticulous preparation, controlled rusting in a damp box, boiling to convert rust to black oxide, and carding to remove loose rust. The process is repeated multiple times for a deep finish, followed by curing with boiled linseed oil.

This video demonstrates a simple heat/oil bluing method for metal finishing, suitable for firearm parts like reloading dies and butt plates. It involves polishing, degreasing, heating the metal with a propane torch until a plum or blue color appears, and then quenching in motor oil. Proper ventilation is crucial due to smoke produced during the process. The technique offers a unique finish distinct from traditional hot or cold bluing.

This video revisits cold bluing using Brownell's Oxpho Blue on a Finn M91 barreled action. It details the critical importance of meticulous metal preparation, including sanding with oiled 240-grit sandpaper to prevent rust and achieve desired luster. Proper degreasing with isopropyl alcohol and heating the metal before application are highlighted as key steps for effective bluing.

This video revisits cold bluing techniques, specifically using Brownell's Oxpho Blue, favored for its forgiving nature and ability to blue over existing finishes. The process involves meticulous degreasing with isopropyl alcohol, careful application of Oxpho Blue using cotton balls and forceps, and buffing with 0000 steel wool over multiple coats. Final sealing with Kano Kroil oil protects the new finish.
