great variety of front sights to be used. With the ramp one is not limited to the use of blade sights made for military bases, but may use any of the dovetail base sights having a rather short dovetail; or he may U3e the caterpillar sights made by Lyman and Marble if he prefers that type. (See Chapter 29).
Figure 152A shows a type of ramp that is becoming pretty well standardized, the solid lines showing the finished shape, while the broken lines show the original blank. The blank should be made by a machinist who knows his business—it is no job for the appren
tice—and it may be made on either the milling machine or shaper. It can be cut from thick walled tubing if the right size is available, or from solid flat stock, using cold rolled or machinery steel. The hole should be drilled and reamed to the exact size of barrel at a point 3/8 inch from muzzle, and it should be a straight hole—not tapered. The trifling taper of barrel at muzzle will assure a snug fit with good contact at rear end of ramp where it is not held by the band. The excess metal of both band and blade should be sawed and filed away, and the ramp brought roughly to shape before fitting. Then start it on the barrel, holding the blade down firmly, and peen lightly until stretched just enough to permit of its being slipped on. Chapter 23 gives detailed instructions for sweating on the ramp, and for pinning if desired. After it is mounted, solder on a temporary front sight, and sight in the arm as outlined in Chapter 29; then follow instructions for ascertaining height for dovetail; cut the dovetail and fit in the permanent sight. This may be mounted before or after bluing—it makes no difference.
A milled blank for front sight ramp will cost from three to five dollars in a machine shop. A cheaper one which is nearly as satisfactory if properly made, is illustrated in Figure 152B and described in detail under the welding instruction« in Chapter 23.
The photo in Figure 153 shows a very attractive ramp made and fitted to a 39 Marlin. The original front sight was removed from the barrel slot, and filed down level with the surface of the barrel. A hole was drilled in this base, and a screw through « held the ramp, which was simply a piece of cold rolled steel 1/4 inch thick tawed and filed to shape. Between ramp and sight base a piece of ribbon
