The Blueing Of Firearms
In this chapter we shall mainly take up shop practice and the various little handling kinks useful in the polishing and blueing of gun barrels or small parts, and will refer you to Angier's Firearm Blueing and Browning a companion book to this one, gotten out by the same publisher for the necessary formulae of various solutions to use or to experiment with. Angier's book is a most complete one in this respect, containing between two hundred and three hundred different blueing solutions, some of...

In rifling barrels, a rifling head to hold the cutter is used, to which is attached the rod or tube which draws the cutter through the barrel. In its simplest form this rifling head is a steel cylinder, three inches or more in length, which will just pass through the drilled and reamed barrel blank. In one side of this a slot is cut lengthwise of the cylinder, just wide enough to accept the cutter which fills the slot from side to side and end to end closely enough so that it has no shake. This...

Sharps Action Sear Lever Trigger
The lock-time of the Sharps Borchardt action is fairly fast as it was made originally, due to the short firing-pin travel but it may be speeded-up still more, as is done with bolt-actions, by lightening the firing-pin, from the rear, to remove weight but, due to the sear notch in the pin, this hole cannot be made very large, although drilling the hole off-center enables you to make a larger hole than if the pin is centrally drilled. Some weight may also be removed from the heavy head of this...

velocities. These higher velocities have generally been rcachcd by decreasing the bore and increasing the powder space. Both of these practices result in increased breech pressures which, if handled with care ana proper steels, need have no bad results, but therein, for the experimenter, lies the catch, for very often he has neither the ability nor equipment himself to build a proper action of the correct steel to give him a margin of safety in his experiments. The result is that he fits a...

Rimfire Rifles
The .22 Rim-Fire rifle is in a class by itself, both as to price and for performance, and therefore deserves some special discussion. It. has some troubles all of its own, so we shall devote some space to them. One of its commonest troubles, even in new guns, is failure to extract the fired cartridge. In the case of a new rifle this is very often caused by heavy grease or dirt under the hook of the extractor and when extraction fails on a gun, either new or old, this is about the first place to...
Mk-19 Spiral Barrel Groove
long spiral. Each spiral will only cut grooves of one twist, so that in rifling barrels of different twists, different guide shafts must be used, each with its own twist of spiral groove. The engine lathe of the screw-cutting type can be used to rifle barrels and the setup is not expensive. Some makers of engine lathes supply spiral attachments for their lathes. These have a set of gears with them and these gears, in connection with the gears regularly supplied with the lathe, will cut almost...
Soldering And Brazing
Soldering is a method of joining two pieces of metal together with an alloy of lead and tin, sometimes with bismuth added if a solder with a low melting point is desired. As lead has the highest melting point of the three, solders containing a high percentage of lead and a lower percentage of tin, or a high percentage of lead and a low percentage of tin and of bismuth have the highest melting point. Lead has a melting point of 620 degrees Fahrenheit, tin a melting point of 445 degrees...

If the case-hardening is very thin it can often be penetrated with a heavy center-punch. In this case, the hole center is carefully marked and the center-punch placed thereon and struck a heavy blow. The drill is then started at low speed, using turpentine for a lubricant, and as long as the point of the drill does not contact the steel, the lips of the drill will cut. The center-punch is driven into the hole several times, as the drilling proceeds, so that the center of the hole is kept...

Shotgun Repairs
Looseness sometimes developes between barrels and action of a double or single-barrel gun of the break-open type. To repair this correctly requires quite a bit of work, as it usually means a new hinge-pin or new bolt, sometimes both. On cheap guns, peening parts to tighten the action is permissible if a low-priced repair job is necessary but it is, of course, a short-lived repair. First, make sure that the barrels bed evenly upon the frame and see that the barrel lug does not bind in its cut in...

In sweating two pieces of steel together, each piece is tinned, giving a thin coating of solder then the pieces are placed face-to-face with the tinned surfaces in contact, are clamped tightly in this position and are then heated with a torch so that the pores of the steel are well opened by the applied heat, whereupon the solder enters these pores making a good joint between the two pieces. The pieces are left clamped together while cooling. This last is a point to be...

head. The cutter is raised to rifling position by placing very thin shims beneath it in the slot. These shims should be only .0002 to .0005 in thickness, preferably the thinner one. After the cutter makes a cut in each groove, another shim is placed beneath the cutter, another cut made in each groove and this process continued until all grooves are cut to the proper depth. A small hole is drilled through the rifling head in the bottom of the cutter slot so that a small pin-punch can be inserted...
