Beginning underwater fishing enthusiasts need to know how to make a homemade gun. This can be done even without special skills, professional tools and precision equipment. There are several key types of underwater guns, differing primarily in the method of throwing the striking projectile - the harpoon. The element that imparts acceleration to the striking projectile and imparts the energy necessary to overcome the resistance of water can be a spring, a special rubber band, vacuum and pneumatics. In addition, hydropneumatic, powder, gas guns and even double-barreled shotguns are produced industrially and made by numerous home-made craftsmen. But since to manufacture most varieties it is necessary to have experience in such work, a variety of materials and drawings to maintain exact dimensions, you should know how to make the simplest homemade underwater gun - an improved version of the so-called Hawaiian.

Beginning underwater fishing enthusiasts will be interested in a way to make a homemade gun without special skills, professional tools or precision equipment.

The Hawaiians, which appeared, as the name suggests, on the islands of Oceania, had an extremely simple structure. Initially, they consisted of a pole with a harpoon tip and a rubber band with a diameter of 10-15 mm, rolled into a circle. Having hooked the rubber band onto the thumb, the hunter used the back end of the pole to pull the rope back to the elbow, after which he grabbed the pole closer to the middle with his hand. After that, all that remained was to aim and unclench your hand so that the compressed rubber band would forcefully push the harpoon towards the target. However, the described method of catching fish is not very convenient for hunting, since holding the harpoon in the “cocked” state requires constant tension of the hand. This drawback can be easily corrected without complicating the design fundamentally, but simply by equipping the Hawaiian with a home-made trigger mechanism. Now let’s talk about exactly how to make a gun for hunting underwater - it’s extremely easy to make, effective and at the same time easy to use.

In addition to sporting interest, making such a homemade product also makes economic sense, since a specialized hunting store will be happy to offer you the simplest harpoon gun for the price of a crossbow. In addition, a tool made to your taste will allow you to enjoy both processes - manufacturing and the hunt itself. Before you make your own underwater gun, you will need to stock up on the following:

• aluminum tube with an outer diameter of 10-15 mm and a length of 150 cm;
• PVC pipe 25-30 cm long, the inner diameter of which is slightly larger than the outer diameter of the aluminum tube;
• a rectangular steel skewer;
• M4 bolt 20-25 mm long with a nut, metal and rubber washers;
• M4 bolt 40-50 mm long;
• steel rectangle measuring 40×15×2 mm;
• three self-tapping screws 70-100 mm long;
• fishing rubber;
• ring-shaped elastic band;
• nylon thread;
• cutting boards with a thickness of at least 20 mm;
• epoxy glue.

Also, to make a gun for hunting aquatic life with your own hands, you will need the following tools: a screwdriver, pliers, a hammer, a chisel, a vice, wrenches, a rasp, a drill, hacksaws for wood and metal.

Separate a 20 cm long fragment from the skewer, clamp it in a vice so that 10-12 mm protrudes from the jaws, and bend the protruding section at a right angle. Having taken the resulting L-shaped part out of the vice, bend it in the direction opposite to the short part of the letter “L” so that you get an arc - a sector of an imaginary circle with a diameter of 50 cm. Drill a 4 mm hole in the middle of the part. In the center of the short tube, drill 2 opposite holes - with diameters of 5 and 4 mm and 2 - with a diameter of 5 mm, 1 cm from the edge. Also, in a short tube at a distance equal to the length between the hole and the bend of the L-shaped part, make a transverse slot measuring 8x2.5 mm. A centimeter from the edge of the aluminum tube, drill 2 opposite holes of 8 mm each, and then make a transverse slot measuring 8x2.5 mm in the center of the tube. From fishing rubber, make a tourniquet 1 cm thick, 40-45 cm long, and every 5 cm, tightly rewind it with nylon thread. From the board, cut a round plug corresponding to the inner diameter of the long pipe and drill a 4 mm longitudinal hole in it.

Assembling the gun

Now you need to assemble a gun from the kit prepared in this way. To do this, screw the L-shaped part with a short M4 bolt to the PVC pipe, inserting a rubber washer between them so that the short part of the L-shaped part fits into the cut in the pipe wall. The bolt head should not protrude above the inner surface of the tube wall, otherwise it will interfere with shooting. Additionally, secure the L-shaped part in the cut area with a ring-shaped rubber band.

Externally, this springy structure vaguely resembles a bicycle hand brake lever and serves as both a trigger and a sear - a part used to cock the weapon.

First, you need to insert a cut wooden plug, after lubricating it with epoxy glue, into the end hole of the aluminum tube. Then weld 3 self-tapping screws on one side and an M4 bolt on the other to the metal plate so that you get something like Neptune’s trident, where the M4 bolt is the shaft of the trident. Lubricate the M4 bolt with epoxy glue. The resulting trident should be screwed into the hole of the wooden plug. The homemade harpoon is ready.

The aluminum tube must be inserted into the PVC tube, and a rubber band must be passed through the 8 mm diameter holes drilled in the aluminum tube. The free ends of the harness are inserted into holes with a diameter of 5 mm drilled in the PVC pipe and carefully fixed there with nylon thread. This is how, without any special qualifications, in a maximum of 1 hour you can make with your own hands an excellent attribute of outdoor activities - an underwater gun.

Trial

To tension the rubber and prepare the gun for firing, it is necessary to move the PVC tube, which acts as a cocking handle, forward to the tip of the harpoon until a characteristic click is heard, indicating that the metal part that has fallen into the slots of both tubes has fixed the gun in the cocked state. Now pressing on the protruding arc of the metal part will disengage it from the harpoon and a shot will occur. Tests carried out in water show that from a distance of about 1 m, the harpoon confidently pierces the wall of a plastic bottle filled with water, and it is quite difficult to remove it back due to the threads on the self-tapping screws.

Conclusion

This is the simplest diagram of an underwater weapon and the shortest instructions on how to make an underwater gun with your own hands. In addition to the described method, there are many more circuit diagrams and manufacturing methods. It is possible to make, for example, a pneumatic gun, in which the harpoon is driven by the force of compressed air, a spring gun, etc.

You should know that homemade means for catching fish under water, like any weapon, require careful adherence to safety rules when handling. There are more than enough cases of careless injury to oneself with this weapon, and the time spent on recovery will be irretrievably lost for fishing, hunting and other healthy hobbies.

In our turbulent times, the need for self-defense is simply enormous. Some may say that special government services should protect citizens. This is true.

But such protection is not always effective. Alas, very often people have to take care of themselves. There are situations from which it is simply impossible to get out of it in any other way except to respond to the attack.

Perhaps such actions may not always completely coincide with the letter of the law, but life and health are more important than any laws. Therefore, every person should have something with him. Or be able to make it in time from available materials. Read this article on how to make a self-defense weapon with your own hands.

Which weapon is better to choose for defense?

In some cases, you can use improvised means to fight off the enemy. It could be a stone, a stick, or just a pile of sand thrown into your eyes.

But such funds are not always available at the right time. In addition, a person may simply get confused and forget about everything.

It’s another matter if a person is already prepared for self-defense. He has a developed plan for such incidents and defensive means at hand. In a world where danger can be found anywhere, you just need to be prepared.

And, above all, a person must have means of protection. Such, for example, as or , or . You can buy them in a store, but it is much more profitable and reliable to use homemade self-defense means. This type of weapon does not need to be registered anywhere, hidden securely and there is no fear of losing it. And it’s quite possible to do it yourself.

Making a baton

A baton is the simplest and most reliable means of defense. It’s impossible to imagine anything simpler. It can be made of wood, rubber or any other material.

This is a pretty accurate weapon. It can be used to deliver quick and powerful strikes.

As a result, severe damage may be caused to the enemy. The main disadvantage of this means of self-defense is the size of the baton. It is inconvenient to carry with you.

Accordingly, it is better to use it at home, protecting the home and its inhabitants from intruders.

Nunchakus

Nunchakus are the most common DIY self-defense weapon made of wood. Using the nunchuk requires certain skills.

They are unlikely to help the person who picked them up for the first time. But a little training will fix everything. Nunchucks are superior to batons due to their convenience. They are smaller and lighter. They are easier to carry with you.

Making nunchucks with your own hands is quite simple. You only need two wooden sticks. Their size can vary from 15 to 30 centimeters.

You need to make a hole at their ends and connect them with a rope or chain. Due to the fact that they are made of two parts, there is almost no shock absorption.

Note: In addition to striking, you can also defend yourself with nunchucks. They will be able to avert a blow from a knife or other object.

Sling

This is a very ancient type of weapon. Memories of him can be found in the legend of David and Goliath. But you can defend yourself with this remedy even now.

To make it you need a simple lace. At one end you need to make a loop. Make a bed for the projectile in the middle. Any small solid object can serve as a projectile. Even a simple pebble.

The sling is used as follows. We put the loop on the hand, insert the projectile into the stock. The other end of the rope must be held tightly in the same hand. After the sling picks up speed, the free end must be released.

The projectile will take off and fly in the direction in which the hand is pointing. Moreover, such a blow will have much more power than if the stone was simply thrown. If you don’t have a sling at hand, you can use a T-shirt or belt as a sling.

You should always think about safety. Moreover, making self-defense means with your own hands is not at all difficult. Watch a video on how to make homemade nunchucks for self-defense and training using improvised materials with your own hands:

Children of the 90s generation did not have newfangled toys and computer games, but they had a wild imagination that allowed them to come up with incredible ways of entertainment. The favorites had something you could shoot with or set on fire. Although these entertainments were considered favorites among children during perestroika, many of them could be harmful to health and even lead to death.

Slingshots

Who remembers homemade slingshots? They were of two types - classic and keyed. The classic ones were cut from a thick hazel branch with a fork, a wide gray rope was bought at the pharmacy, a piece of leather was obtained (you could secretly cut houses from a travel bag and dump it on your sister) and everything was fastened with copper wire or blue electrical tape.

Such a slingshot was loaded with smooth pebbles, which were often brought into courtyards along with sand or unripe berries, such as rowan, plum or cherry, which grew in abundance behind the house. The power of the stone shot was sometimes enough to shatter a champagne bottle from 3 meters away. Such a slingshot was valued because not everyone had the skills and funds to create it. It could be exchanged for other valuables such as inserts from Turbo, CinCin and Final90.

While walking and having nothing to do, it was possible to make a simpler slingshot - a keyed one. To do this, in a landfill it was necessary to find a thick aluminum wire in a braid and find a flagellum. As a rule, there were no problems with the latter - it was easily obtained from the elastic band of panties. The newer the panties, the better the flagellum. From all this, something like this was assembled (pictured on the left). Such a slingshot fired with dowels - pieces of copper or aluminum wire bent into a horseshoe.

Crossbows

A heavier version of the slingshot was the crossbow. A wooden clothespin was attached to the board, and an elastic band was attached to the other end in such a way as to create a “loop”, the saddle of which falls just on the clothespin. With the necessary stretching, of course. A “bullet” was placed in the elastic loop, the elastic was stretched and clamped into a clothespin. When the clothespin was pressed, a shot was fired. They shot with the same rowan berries, peas, peppercorns or pellets.

Samopal

The most advanced version was called self-propelled guns. This is closer to a real firearm. A thick-walled metal tube was sealed at one end (flattened and topped with lead), and a 1mm hole was drilled near the blind end. The pipe was attached to a wooden stock, usually in the shape of a pistol (again, sometimes the same chair leg was used). “Sulphur” from matches, a wad and a homemade sub-caliber lead bullet were driven into the tube using a ramrod. The shot was fired when a special striking frame, released by the trigger, struck the head of a nail inserted into a small hole. The bullet had a very serious destructive force - 15 match heads in a 4mm barrel drove the bullet 5 centimeters into the tree. It would have been better not to end up with the police with a crossbow...

Match shooter

Another lightweight weapon was the match shooter. It was made from wooden clothespins. Do you feel the usefulness of this Soviet device? He shot with ordinary or burning matches at a distance of 10 meters. To make it, a wooden clothespin was dismantled, a place for a spring (from the same clothespin) was sharpened with a file, a “barrel” was sharpened, a spring was put on one of the halves, the halves were connected by their reverse sides and rewound with electrical tape. The spring played the role of both the trigger and the pusher at the same time. Sometimes a piece of “chirkash” from a matchbox was attached to the “trunk” so that the match would light itself at the moment of the shot. More often they simply passed the box over it and immediately shot.

Dart

Probably only the lazy didn’t play the game of darts; we also loved throwing darts as children. But they weren’t sold or they cost a lot of money. Therefore, almost any boy in our yard could make it himself. In terms of its flight and insertion qualities, the dart turned out to be no worse than the factory one. A piece of paper, 4 matches, a needle, office glue and thread. They hung a homemade target from a notebook sheet on the wall carpet and played.

Pistons

Who had such a revolver that fired such caps? But it was more interesting to poke something sharp at the brown spots and watch them ignite. Or it’s even more interesting to roll up a roll from a strip of piston and hit it with a hammer. Ringing in the ears for 10 minutes was guaranteed!

Who sees the connection?

Scarecrow made of bolts

And here?

I think our generation will easily explain the connection between these objects. They hammered the dowel into the asphalt with a brick, took it out, crushed matches into the hole, inserted the dowel and threw a brick on top... Bang! and the piece of asphalt was gone... :) Matches cost 1 kopeck per box and were freely bought in the store.

And these are already “rockets”

Slate in the fire

I think you can easily remember what happens to slate in a fire :) That's right, nothing good - it shoots a lot. In pieces.

Lamps and picture tubes

It was a sin not to break a fluorescent lamp thrown into the trash. They broke with a loud bang if you threw the lamp end-on onto the asphalt. They didn't think about the environment back then...

But this find in the trash heap was extremely rare and always brought great joy to the boys. They cast lots to see who would be the first to throw a brick at the top lamp (the ray gun of the kinescope). She was the most vulnerable point of the kinescope. When the lamp broke, the picture tube, due to the internal vacuum, collapsed inward with a very dull bang that echoed in the courtyards. Neighborhood boys immediately came running to see this action. But more often we found picture tubes with a broken lamp...

Siphon cans

Used cans for carbonation machines (siphon) were also sometimes used. They were filled with sulfur from matches and the hole was closed with a bolt. Then the infernal device was thrown into the fire... I must say that this thing was the most dangerous invention of the yard boys. Personally, I have never made such a balloon. And I categorically do not recommend it to others.

Magnesium

We mixed magnesium, crushed into powder by a file, in a certain proportion with potassium permanganate, which cost a penny at the pharmacy, and wrapped it in a tight paper bag, also wrapping it with adhesive tape. They made a hole and screwed a match to it, so that the head of sulfur was exactly in the hole. They struck a match on the box and abruptly threw it aside. The package exploded with a deafening noise and a bright flash.

Knives

In my opinion, every boy had a folding knife as a child, which was a source of pride. With its help they played “country land” and “tanks”. Each game had many types of rules. For example, “countryman”: they drew a circle and divided it equally by the number of participants. Everyone stood in their own area. Then, while standing, they stuck a knife into the enemy’s area and cut off a piece of his land. “I got wounded” (didn’t stick it in) - the move passed to someone else. And according to one rule, you had to stand on your land all the time as long as you can. According to others, you could stand outside, but in the event of a catastrophic reduction in your area, the enemy offered you to stand on it for 3 seconds. If you can't resist, you're out. You could even stand on tiptoes of one leg - the main thing was to hold out for 3 seconds.

Carbide

Who remembers the magic stones with a specific smell that bubble in water? Carbide is a joy for the finder, for the whole day! When combined with water, it reacted and released the wonderful gas acetylene. It is remarkable because it burns well. Carbide was used in whatever form. And they simply threw it into a puddle, setting it on fire. And they warmed their hands, squeezing the carbide in their palm, immersed in a puddle. And they put it in bottles of water, plugging it with a stopper...

But the most effective use of carbide was in the hand cannon. They took an empty deodorant or Dichlorvos bottle, cut off the neck, made a hole at the bottom, put carbide inside, spat on it liberally, plugged all the holes, shook for a minute, opened it and brought a burning match to the small hole... VOLLET! !! :)

Dymovukha

The absolute truth is that only our generation knows what the connection is between a child’s tumbler or a tennis ball....

But we know what will happen if pieces of this special, magical plastic are wrapped in foil or newspaper, set on fire and extinguished... How much nerve did the guys spend in their garages when such a miracle flew to them from the roof...

Lead

How much in this word merged for a child’s heart... And merged in the literal sense of the word. Remember how you scoured garages and searched car dumps in search of old batteries?

They split them and extracted pure lead. They beat out the dried electrolyte and crushed the soft metal into a tin can or bowl.They made a fire and waited for the liquid metal to sparkle in the jar.

And then they did whatever their heart desired!

Shooting toys can be bought in a store without any problems, but you can successfully make them yourself. On the pages of the website Secret of the Master, various designs of cool toys are considered, from the simplest to the more complex, which, in addition to gaming and experimental purposes, can bring practical benefits, for example, in protecting crops from pests at the dacha.

This is a serious design in terms of sound and projectile. The main application is to imitate the sound of a hunting rifle shot to scare away birds. A reliable budget gun, but only if used correctly and sparingly. Strictly follow safety rules and assembly recommendations. See how to make an Apple Gun

Finding yourself alone with nature, you have to survive by getting food using improvised means. It’s good if you have a bladed weapon or a hunting rifle with you. If you find yourself in a situation where you have neither one nor the other, you can make a weapon out of wood with your own hands.

Almost any weapon can be made from wood: a bow, a crossbow for hunting, a knife, a spear, a spear, a slingshot, an ax and even a gun. More details on how to make weapons from wood are discussed below.

Homemade knife, wooden

The choice of material for making weapons is a very important task.

• Birch is a strong and unyielding material; it is best used to make batons.
• Aspen, poplar and pine are softer and lend themselves well to various types of processing.
• But the most suitable wood for homemade wood is oak. Oak wood is well processed, light in weight, durable, and does not lose its characteristics over time.

Before making a workpiece, you need to select a material that does not contain knots, rotten areas, distortions, or heterogeneity of fibers, then dry it without exposure to direct sunlight. When the material is ready, weapons preparation is made.

DIY wooden slingshot

Slingshot

The simplest wooden weapon is a slingshot. With the help of this throwing weapon you can hunt birds and small game, and for production you need a minimum of materials - a strong elastic band or a tourniquet, and a branch with a fork (it is better to use hazel).

The fork is cut from the main part of the barrel to the required size, polished, and a tourniquet is attached to both ends. For reliability, you can make small cuts at the ends of the slingshot so that the tourniquet does not slip off.

Wooden club

A similar simple weapon is a wooden club. The disadvantage of this projectile is that to use it you need to maintain a short distance, which can be very difficult during hunting. To make a club, you need to use a young tree, cut down closer to the root, where the wood is most durable. The bark and all the knots are carefully removed from the surface of the workpiece, it is soaked for a day in water, then dried over a fire until black, which is then removed by sanding with sand and grass. This procedure must be done several times, resulting in a durable club that does not rot.

DIY wooden knife

Wooden knives

An equally complex homemade weapon is a wooden knife. It can be cut in one piece from a wooden block, or it can be made from two components. To do this, you need to draw a sketch of the workpiece on wooden blocks, then cut it out with a hacksaw. After this, both parts are glued together into a single whole. If the manufacture of a wooden knife is carried out in field conditions, then, as a rule, there is nothing to glue the component parts with. Therefore, it is cut from a single block.

The blade is well sharpened and carefully polished, after which it must be fired over a fire, giving it strength. If possible, you can varnish the knife, then it will not be afraid of moisture.

Wooden bow and crossbow

A bow or crossbow is an effective weapon in the forest, made of wood. There are many video examples of crossbow making that describe the entire process in detail. First, the crossbow body with a groove for the arrow is cut out. An arc will be attached to one end of the body, and a trigger mechanism will be made at one third of the other end. It is better to make an arc from several layers of plywood glued together, which bend after drying. You can make it out of metal. At both ends of the crossbow arc you need to make holes for attaching the bowstring. The arc is attached to the body using a strong rope; if it is not at hand, using wire. The bowstring is attached to the bow in such a way that it passes closely over the body, but does not touch it. The task of the trigger mechanism is to capture the bowstring and sharply release it. The design of the mechanism can be made in the form of a wide arc or a complex system of hooks.

Arrows for crossbows are made of elastic wood, they are given a cylindrical shape, after which they are polished. The tip can be made of wood, metal or stone.

Not only “cold” weapons can be made from wood. You can make something like a pistol or shotgun, but you need to understand that it will not last long. The algorithm for making a pistol is simple: you need to make a frame from wood to which the barrel is attached, as well as a trigger mechanism with a striker, you can add a magazine. A metal tube is used as a barrel.

It is difficult to make a full-fledged pistol from wood, but you can make a dart shooter, which will become a full-fledged hunting projectile. In order to make it, you need to cut a cylinder from an empty aerosol can into which a piston cut from wood is inserted. To ensure normal friction force, a rubber skirt is attached to the piston. Next, the rod is made using a large nail and a spring. Inside the wooden frame you need to make a hole into which a cylinder with a piston is placed. The trigger mechanism is made in the same way as a crossbow; more detailed installation process can be found in the video. The barrel of the dart thrower needs to be made using a metal pipe, and nails for the darts.
