![]() ![]() The wire brush, turning in and coated with the fairly coarse abrasive compound, will make well-defined complete circles on a rounded surface while the solid abrasive rods may not. The part to be processed is given a thin coating of the abrasive paste and the wire brush brought into contact with the surface. The wire brush must be used with an abrasive paste compound mixed with cutting oil. Hither of these is mounted in a drill chuck and turned at a fairly high speed. This spreading can be prevented by slipping a tight-fitting O ring or a short length of heat-shrink plastic tubing over the brush, leaving only about 1/8 inch protruding. These brushes will begin to spread out as they are used and make a progressively larger pattern. The commercial holder doesn't cost much, so it should be used if possible.Īnother, better, method is to use small wire brushes of 3/16 or 1/4 inch diameter mounted on a stem that can be secured in a drill chuck. They can also be held in thin-walled tubing or a rod with a hole drilled in one end. These are contained in a holder especially made for the purpose and availableįrom gunsmith supply houses. These tools can consist of small abrasive-loaded rubber rods, which are usually 3/16 or 1/4 inch in diameter. This is normally done using an abrasive-tipped tool chucked in a drill press. The process consists of overlapping polished circles of small diameter, equally spaced lengthwise and crosswise, or around the circumference of a round bolt. It is also handy for covering minor blemishes that cannot be removed easily. Properly done, this process adds considerably to the appearance of the finished firearm. So lefs take a look at some extra ornamentation that will usually be the attention getter required to make our gun stand out from the others and be noticed first.Įngine turning, also known as damascening and spot polishing, is a type of ornamental polishing used mostly on breech blocks, or bolts, and magazine followers. The worst trouble is, most of the others may be equally well finished. This should be enough to attract and hold anyone's attention. The wood is smooth and without tool or sanding marks, with all pores of the grain filled, and a slick, smooth, even finish applied. Lines remain straight and well defined and corners sharp and square. All metal surfaces are finished free from tool marks and blemishes, with all surfaces flat and true. Therefore, we will finish all exposed surfaces to the best of our ability. Whatever the reason, the prototype gun that we have spent so much time and effort to produce should be an attention getter. A good bit of the time though, it will be due to extra ornamentation such as engine turning of bright parts, matting and metal checkering, or an outstanding checkering job. ![]() Or maybe more attractive figure or graining in the stock wood. Almost invariably this is due to the one having a better finish. This happens even when the entire group consists of the same make and model. There are times when, as a number of good guns are displayed together, either standing in racks or laid out on display tables, one among the group will divert attention away from the others. ![]()
