Barrel Changing And Its Adjustments

One of the commonest major operations on guns is barrel replacement. When the new barrel is a factory standard for the gun in the case this is usually a simple job on rifle or shotgun, as these factory barrels practically always screw right up to the proper place. Removing the old barrel is not always so simple. If it is an octagon barrel, remove the tubular magazine, if the rifle is so equipped, and withdraw the breech-bolt far enough so that the extractor clears its slot in the end of the...

Blueing Hands

To try something different if the results at first do not turn out as you would have them. For convenience and speed in blueing guns, three tanks are necessary. These three tanks can be made of 24 to 26-gauge black sheet-steel or iron, such as can be obtained from any sheet-metal shop or stove and furnace installation outfit. They are best made by be ing bent to shape from a single sheet for each tank, with no soldered joints and therefore no chance to develop leaks. There is however, no...

Heat Treatment Of Steel

Heat treatment of steel causes a rearrangement of its grain structure, resulting in a harder, tougher product. To accomplish any change in the grain structure, the steel must be heated to what is known as its critical point or range, whereupon a change will occur in the metal at the lower edge of this critical range and again at its upper edge. The desired change to refine the grain structure occurs within this range, between the low point and the high point in temperature. This critical range...

Chambering Boring And Reaming Tools

Chambering reamers may be purchased from firms specializing in this work, from barrel makers, in some cases from gun factories or the gunsmith may make his own reamers. Reamers for popular calibers for which the gunsmith often fits barrels should be made in sets of three, a roughing, a finishing and a burnishing reamer. These reamers should be made of high-speed steel to minimize wear. Reamers for a caliber which is seldom called for, or a reamer for a special job, may be made of carbon-steel...

22 Caliber Rim Is Bent Upon Firing

Proper Trigger Pull

Nccessary is the thorough polishing of contact surfaces of the full-cock notch and of the sear. This is done with the fine carborundum and the white Arkansas hand stones. If the double-action pull of a revolver is too hard, examine all parts, including the cylinder ratchet and the hand which engages it, for burrs. These, when found, are polished off with the white Arkansas stone. A dragging cylinder lock will also cause a heavy double-action pull. This is easily discovered by examining the...

Appliances

All of the late-model loading tools and some of the earlier ones are readily adapted to various cartridges by changing the dies. A majority of these loading tools have the dies attached to the tools by threaded ends. This makes a somewhat slow method of changing dies but on the other hand has two advantages first, that of security of fastening second, that of adjustment, for the threaded ends allow the dies to be moved in or out of the body of the tool to adjust them to the proper length for...

Cartridge Case And Bullet Dies

202 Bullet Cases

As special cartridge cases are usually made by necking-down an existing case of larger caliber, a full-length die to neck the case down is required. This can be made in two different ways, the first of which is to turn up a reamer blank in the lathe to the form desired for the special cartridge. This reamer blank, instead of being fluted as a regular chambering reamer is made, is usually cut away between the pilot and the shank, to one-half its diameter. This is done either in the milling...

How To Spot Enealle A Hardened Receiver

Homemade Rifling Machine

In cutting dovetail in barrel by hand, the slot is roughed out with hack saw cuts. A small chisel is then used to chip away the metal between saw cuts as shown, after which the slot is finished to size red. The material is turned at high speed and a very sharp tool is used to shape it. In the case of the regular beads, the shank should be about long. The shank is made a fairly close fit in the blade and Dupont cement is first put into the hole, the shank of the bead is then pressed in and the...

Action Work And Alterations

Bolt-handle bending, or cutting-off and replacing the bolt-handle at a different angle, is a job often desired on military and other rifles but this is a job that must be carefully done if the working parts of the bolt are to be properly protected from the heat. In bending a bolt-handle to a different angle, all removable parts are stripped from the bolt and its interior is filled with a long, narrow strip of cloth, packed into place with a rod or narrow-bladed screwdriver. This cloth is now...

Front Sight Deviation Photos

Probably the poorest way to attach sights to the gun barrel is in the time-honored dovetail slot but this has been done from the earliest days, is still being done and is often demanded by the customer, so a word or two about it will be in good order. It is sometimes neccssary to cut a few inches from the muzzle of a rifle which has a front sight in a dovetail slot, so if any great amount is taken off the barrel must be slotted further back. Small milling cutters to mill these slots must...

General Electric Heat Treat Furnace

The pyrometer is used to check these high temperatures, as they are above the range of a thermometer. The element of the pyrometer which is subjected to the heat of the furnace is protected by a metal or ceramic case. For average use, the nichrome tube is regarded as the best protection for the element. With continued use the metal of the element gradually disintegrates, causing a change in accuracy of the pyrometer. For this Non-recording, non-controlling type pyrometer for high temperatures....

The steel may be bent around in a close curl. The lever is bent around the cylinder of steel in the same wa.y the tang was bent. If the lever is of the loop type, such as is often found upon a rifle, the bending is a more complicated process. It is best done in an arbor press, using three steel rods or brass rods, but it can be done with a vise. In doing it on a press, two rods are laid on the pressure plate of the press, spaced a short distance apart, and the lever is laid upon these, bottom...

How Rifling Machine Working

With the 87 grain bullet loaded to its highest permissible velocity and it would probably handle the 60 grain very well. Therefore, in recutting old barrels it is not possible to use the old barrel itself for a rifling guide unless the twist of the old barrel and the required twist for the new cartridge are the same or very nearly so. Two instances of this are the .38-40 being recut to .44-40 the twist in this case is the same, one turn in 36 inches, and in recutting the .30-30 to .32...

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...

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

Smooth Bore Rimfire Rifle Pics

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...

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...

Nose, for center-fire cartridges, should be .073 to .075. This diameter is taken just at the rear edge of the hemisphere that forms the actual point of the center-fire pin. The protrusion of the center-fire pin beyond the face of the breech, with the pin in the fired position, should be .055. These dimensions and shape of point apply to all center-fire firing-pins, whether for rifle, revolver, pistol or shotgun and, furthermore, they are highly important from a standpoint of both safety and...

Shotgun Repairs

Parker Shotgun Hammer Screws

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...
