This week's reflection assignment consists of one video. It features Mr. Larry Potterfield (founder, and CEO of Midway USA) as the presenter. The video is titled "Gunsmithing: How to properly polish the metal parts on a Remington 700".
Mr. Potterfield begins his first video by stating the objective, polishing metal parts. In his hands, he holds the barrel of a Remington 700 series rifle. It appears as if the rifle has definitely seen some cleaner days, in my opinion. This is a skill every gunsmith must be well versed in, in the field of gunsmithing. For this task, he must sand to a 320 grit, for the best results when it comes time to bluing. He shows the classic looking barrel, and compares it side by side to a hot water method blued barrel. The hot water has a glossy black to it, while …show more content…
Mr. Potterfield states that first off, you would have to clean any machining marks. He has a file set, abrasive papers, and sanding blocks. He states that the preferred method to polishing is by hand. To prevent the rounding of edges, he uses a firm background in conjunction with the abrasive paper. It also serves to aid in uniformity as well. For removing the excess solder, he first secures the barrel in a vise. Next, he uses a file. For the sights and barrel band, he secured abrasive paper to tongue depressors. He can then cut them to size, and they include a backing. After he polishes with 220 grit, he moves to 320 grit to remove any marks. He shows that the final pass is the length of the barrel, in a side to side motion. To prevent rust, he coats the barrel with some oil, and brushes it across the surface. For the receiver, he uses some blue remover in order to get to the surface of the bore.
