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.
