Doityourself Machine Pistols

Building an SMG from scratch is not an easy job for most people, even though excellent plans are available from various sources. Not everyone has the shop, tools or skill required. Converting a semi-auto pistol would seem to be a more practical approach. These conversions still appear to be difficult to most folks, who believe that complex machine work and hard to get parts are needed. All of these objections are true sometimes, for instance, to change an M-I carbine to M-2 (a favorite)...

Means Of Projection

During the World War, chemicals were disseminated by every military arm, although the air corps did not use toxic gases. When chemical warfare made its appearance in 1915, there was already a large variety of high-explosive weapons in use. As chemical warfare was bom during the war and there was no prewar development of its mat riel, the first chemical munitions wTere hasty adaptations of high-explosive weapons, although subsequent experience showed that some of these weapons were not suitable...

Every particle of liquid, or solid, in contact with a gas is surrounded by a film of gas closely adhering to it and capable of removal or penetration only by the projection of another solid or liquid particle through it. This film serves as an effective insulator, separating the particle from the gas around it, and breaking down only through mechanical rupture. When such a particle travels through the gas, the film moves with it when the gas moves past the particle, the film is distorted and...

According to this Invention weight cf the weapon is kept to a minimum by constructing certain elements so that they per* ions two or more functions. For example, the trigger guard of this invention is arranged in such manner as to afford protection for the outwardly protruding trigger and also so as to function as guide means whereby...

Plastic Bombs

Hand grenades and antipersonel mines can be easily and cheaply constructed from polyester casting res in, auto body putty, ABS and PVC pipe, plexiglass, vacumn formed styrene sheet etc. These plastic devices won't produce shrapnel fragments or concussions equal to the power of conventional bombs, but they do have two unique and noteworthy features they are both non metallic and x-ray Li.apparent. The first feature allows these devices to be carried through airports, government buildings and...

Future Of Lacrimators

The future role of the lacrimators in war is uncertain. Their great advantage is the extremely small amounts required to force men to mask with the attendant impairment of their fighting vigor. On the other hand, they produce no real casualties and protection is easily obtained. For these reasons, it seems fairly certain that lacrimators will not be used in any future war between first-class powers, as their armies will be equipped with masks affording adequate protection. At the same time,...

All that is left is to install the new shoulder stock, give the whole thing a good safety test and you're in business The Sauer M-38 is even easier to alter than the Colt. Start by stripy-ping the gun. The Sauer is stripped by pulling down the latch in the trigger guard, then pulling the slide all the way back and up, then letting it go forward off the frame. Then remove the grips. To start the conversion, remove the trigger bar (see drawing) by...

WaterTipe

The walking stick shotgun made from water pipe which was featured in PMA could be a very handy weapon, except that it's unsafe to carry. Besides the danger, it could be very embarrassing as well as a detriment to your continued freedom to have your'walking stick' either fail apart or go off at the wrong t i me. You can eliminate this potential hazard by putting in a pin type saf-ty lock.This Is simply a piece of 1 8 or 3 16 drill rod slightly longer than the diameter of piece number th ree and...

Physical Classification

The physical classification is very simple and is based upon physical state or form of the substance under ordinary conditiona, i.e., temperature 68 F. (20 C.) and atmospheric pressure (760 mm. Hg). Thus, an agent is a true gas, if its boiling point is below ordinary atmospheric temperature, as is the case with chlorine (b.p. 28 F.). This classification as a true gas is not to be confused with the broad generic term gas, used to refer generally to toxic chemical agents, but means that the...

a working model and it was an instant sucess. Really though, it couldn't have been anything but a success, as It was so very simple in construction. This first bazooka consisted of nothing more than an aluminum tube six feet long and 3 A to I inch In diameter, a motorcycle battery (power pack), a light switch (trigger), and the necessary wiring and electrical connections. These parts were all taped together for easy assembly and disassembly. The assembly goes as follows The wiring goes from...

Hohemaoe Bazooka

The subject of improvised weaponry has been a topic to which much thought has been devoted. However, until recent times in the light of massive anti-gun IegislatIon,it has been somewhat crude and ineffective. Taking these facts into mind I decided to design, build and test a weapon that would be easy to make and highly effective. Ater toying with the idea and encountering a few failures, a friend of mine developed the Idea of the bazooka. He later built

Comparison Of Smoke Agents

Group II White Phosphorus WP

One of the earliest and by far the most efficient material used in the war for generating artificial smoke was phosphorus. This element exists in two allotropic forms white phosphorus and red phosphorus. White phosphorus, the normal and common form, was discovered in 1669 by the German chemist, Brand, who noted that it is spontaneously inflammable at ordinary temperatures and burns with a dense white smoke. While both white and red phosphorus were used in the war, white phosphorus was by far...

No m-nitrotetryl is produced if pure dimethylaniline is used in the usual process for the manufacture of tetryl. The amount of this impurity in the usual process depends upon the amount of monomethylaniline which may be present. A large excess of sulfuric acid tends toward the production of m-nitro compounds, but a reduction in the amount of sulfuric acid is not feasible for this increases the amount of benzene-insoluble material. m-Nitro-tetryl reacts with water, as TNA does the nitro group in...

Dissemination By Projectiles

While the theoretical economy of releasing chemicals on the target area is very large, as indicated above, the practical advantage is not nearly so great, for several deterrant factors enter into the projection and dispersion of chemicals from projectiles. In the first place, projectiles are not very efficient as carriers of chemicals, for their walls must be made thick enough to withstand the shock of discharge, and this greatly limits their chemical capacity. The efficiency of a chemical...

Command Post

Place your manually detonated mines in spots that can be readily identified by you. If you put one in a tree stump, run the string into your command post, put a little tag on the pulling end that says 'tree stump'. If you have a big project like a long wall that you want to dot with mines, put numbers on the wall facing you and tag your strings accordingly. By doing this, you just sit back and wait for someone to take his position, and then finish him off. If you are being stormed, pull all the...

SiCl HjO Si OH i HCI

At a concentration of 0.20 mg. per liter, no further hydrolysis takes place, but an equilibrium seems to be established in which the hydrochloric acid liberated prevents further decomposition. In fact, when the hydrochloric acid becomes too great the above reaction may even be reversed and the amount of smoke actually diminished. If, however, the excess hydrochloric acid is neutralized by reaction with ammonia, hydrolysis of the silicon tetrachloride proceeds smoothly SiCL + 4NHi + 4H,0 - Si...

Use Of Vesicants In The World

The vesicants rank second in the extent of use in the war, being exceeded in tonnage by the lung injurants only. Altogether, about 12,000 tons of vesicants were used in battle, and of this quantity it is estimated that mustard was fully 95 per cent. No separate records are available as to the exact quantities of the minor vesicants that were used, or as to the casualties produced by them. Mustard gas so nearly completely dominated the vesicant field that all such casualties are generally...
