Make a children's crossbow out of plywood. How to make a crossbow with your own hands at home. Three execution options

In addition, it will be interesting to shoot from such a gun yourself. Everything is done quite simply, here you can completely do with hand tools. The crossbow turned out to be quite powerful, as for training shooting. It uses double shoulders, which increases the rigidity of the bow and allows you to throw wooden arrows at high speed. The author uses self-tapping screws as an arrowhead, but you can show your imagination and come up with something more interesting.

Materials and tools used

List of materials:
- timber;
- PVC pipe;

The process of making a crossbow:

Step one. Cut out blanks
First of all, we will cut the wooden beam, it will be used to make the base. We also need to cut the pipe. You should have two pieces, a long one and a short one. See the photo for dimensions.

Shooting, as a kind of sport and the ability of self-realization, has been popular with people for a long time. An indicator of this are countless competitions with the use of a variety of weapons. The 1st of the oldest types is throwing weapons. The heightened emotionality of today resonates with archery and crossbow tournaments.

Sports shooting from a crossbow in our state is not as developed as archery. This state of affairs is due not to a lack of interest, but to an obvious shortage of shooting equipment. The crossbow sport itself certainly contains many advantages. We offer today to make a crossbow with your own hands. It will be a wide field for the sake of disclosure as well as the application of some kind of talent.

DIY crossbow made of wood

Our crossbow differs in that we chose the shoulders from the bow as the elastic component. This selection is justified by a lighter weight, in contrast to steel shoulders. Plastic shoulders also even out physical contact from heavy recoil. To gain the ability to shoot accurately at distances up to 60 meters, it is enough just to stretch these shoulders without applying much force. The ability to use shoulders from broken bows is another positive feature of our device. The main thing is to find a pair of strength. We advise you to carefully study the crossbow drawings and start assembling. Create a crossbow - do not go over the field. Read on to learn how to make a crossbow with your own hands.

Crossbow device: bed, shoulders, trigger mechanism, sighting devices.

To create a bed, real wood is used, solid or glued, mostly hardwoods. Approximate dimensions can be seen in the pictures. (1 and 3)- crossbow drawing. We choose the shape of the arrows ourselves, guided by the convenience and ergonomics of the bed, the desired image. When choosing, it is also necessary to take into account the possibility of correct manufacture.

The use of a small arms stock makes it possible to significantly reduce the energy consumption for the manufacture of a crossbow. The trace from the trunk, remaining in such a box, must be hammered with wooden blocks, firmly planting them on epoxy glue.

The window from which the crossbow arrow will fly out must be opposite the groove that directs it. This is how the window must be located on the bed of the cross, containing elastic elements. At the same time, at the moment of departure, the bowstring can be pressed against the smooth plane of the bed. Fastening of each shoulder to the crosspiece is carried out with the help of 2 M8 screws. The mechanism for triggering the release device was created in accordance with the description of the device of medieval crossbows. It can be made without any special problems even with an average level of illumination in the workshop.

Do-it-yourself crossbow trigger mechanism

In the process of pulling the crossbow, the bowstring is pressed against the protrusion 6, the lever 2 takes its original position. Spring 6 acts on the trigger so that it rotates, the lever and the bowstring are fixed. In order to prevent the bowstring from accidentally jumping off the ledge a, the trigger mechanism is closed with a cover 7. A spring 8 of a flat type is attached to this cover, which holds the arrow on the guides at the moment of aiming the sight. Bearing 9, which is mounted on the tip of the trigger, sufficiently weakens the force of the trigger. The selection of the trigger force level is carried out by sawing the surface resting on the lever bearing 2. In order to reduce the weight of the lever, it is better to make it from D16T light alloy. Springs 5 ​​and 6 can be replaced with safety pins. The escapement mechanism can be mounted in a metal case, after which it is inserted into the nest of the bed and secured with two screws. In this way, reliability and ease of adjustment can be significantly increased. But this method makes the design more complex, and metal-cutting machines will also be needed for its implementation.

The sighting device of the crossbow consists of a rear sight and a front sight. Vertical adjustments are carried out entirely, mounted on the cover of the trigger mechanism, and horizontal - with a front sight mounted on the bracket of the elastic element.

There can be many design options for these devices, depending on the possibility of manufacturing, the availability of ready-made sights from sports bullet weapons, etc.

It should be borne in mind that the trajectory of the crossbow arrow is quite high, so the rear sight must be mounted well above the front sight. Angle of elevation of aiming line ( see figure 1 - crossbow blueprints) depends on the weight of the arrow, the tension of the bowstring, the shooting distance, etc. In our crossbow at a distance of 50 m, it is approximately 6 °.

The design of the crossbow rear sight is convenient, allowing it to be removed or folded during transportation.

Our homemade crossbow, the manufacture of which is described above, is designed to shoot crossbow arrows with a diameter of 8 mm and a length of 350 mm. Arrows for a crossbow can be easily made from a duralumin (D16T alloy) tube with a wall thickness of 0.5 mm. The arrow is equipped with a tip and plumage, as is done for archery. It should be borne in mind that the shank of an arrow for a crossbow, unlike an arrow for a bow, should not have a cutout for a bowstring. It is convenient to carve it out of wood in the form of a cork and insert it into the end of the tube with glue.

In conclusion, I would like to express the hope that you have understood how to make a crossbow, making it on your own will give you a lot of pleasure, and shooting from it will give you the opportunity to have a good time in the fresh air. Do not forget only that the crossbow, like any weapon, requires a responsible attitude and compliance with all safety measures when shooting. And the amount of pleasure directly depends on how the crossbow is made.

Crossbow Arrows (Bolt)

The center of gravity is between the second and first thirds of the bolt. And this, mind you, is already assembled. True, the parameter can be changed at your own discretion. Also, due to the different material used for the shaft, the sizes and materials of the socks and tips, it is possible to change the mass of the bolt.

To protect wooden shafts of bolts from moisture, they are impregnated with special protective compounds, and also stored in a horizontal position.

For shooting from a crossbow, you can use fairly heavy arrows, even welding electrodes. That is why a clear definition of the optimal bolt is a serious matter. In the process, the required mass of bolts for your crossbow is selected, it is worth remembering the golden mean: if the bolt is heavy, it does not fly far, and light - it quickly loses speed.

If the bowstring is of high quality plus it is well taken care of, you will use it for a long time. As a rule, steel (strings or cables) is used for the bowstring or silk is woven. True, in our time there is a huge amount of synthetic materials. If you make a bowstring from Kevlar, it goes like a material with high resistance (specific) to rupture.

Do-it-yourself crossbow drawings

Do-it-yourself block crossbow

Technical characteristics of a homemade block crossbow:
Overall length -730 mm;
Overall width - 530 mm;
Shoulder length -300 mm.;
Height without sight - 180 mm.;
Height with a sight - 230 mm.;
Weight ~3kg;
Arming force ~30 kg;
Bowstring travel - 210 mm;

Type of sight - only optical (software 3.5x17.5 is installed, mounting brackets of the "dovetail" type).
The material of the shoulders is a spring from 412 "Muscovite", cut it with a "Bulgarian", to avoid vacation it was constantly poured with water, the holes were simply burned by electric arc welding (the edges did not seem to be released);

The trigger force varies from about 1 to 1.8 kg, the trigger works with a warning, an increase in effort is felt before the shot. Shooting indicators (shooting was carried out lying down from a stop in a closed room, a distance of 25 m in three series of 5 shots, fiberglass arrows, weight 25 g. Length 300 mm. Triple plumage height 8 mm):
- maximum radius from the midpoint of impact 75 mm.
- maximum diameter between extreme hits 120 mm.
- average radius of 100% hit in three series 68 mm.

The trigger mechanism "swivel nut with a sear", made of spring scraps, first annealed (t0=8500C red heat, holding for 10 minutes and slow cooling with a furnace) and carried out all the metalworking, but left an allowance for processing in places where it will take place friction, then hardened to about 45-46 HRC, (t0=8300C light cherry scarlet heat, exposure 10 min.) and tempered (t0=2950C bright blue tint, air cooling). Then I polished all rubbing surfaces. The mechanism itself is installed directly into the guide on the pins. The springs are made from a folding metal meter.

The stock was cut from solid wood (oak was taken), the base was a 30x180 board, the groove in the center was selected using an electric jigsaw, a drill and a narrow chisel, the processing was first done with 10% ferric chloride (gives a black color), and then varnished, but I don’t have such a coating I liked it, too slippery in wet or sweaty hands.

I had to sand everything and treat it with special impregnation (I used Danish Oil, which is used specifically for impregnating wood on knife handles), covered it several times until it stopped absorbing, and then sanded it in places of retention with fine sandpaper (~ 500-100 grit for imported paper).

The size of the butt is adjusted personally for me, so if you repeat, then do it with a margin, and then adjust it. The guide is assembled according to the type of package duralumin / getinax / duralumin / getinaks / duralumin, on M3x35 screws, the central plate comes out from below for mounting with a butt, assembled on M6x30 furniture bolts with a semicircular head, on the opposite side it is attracted by nuts (the holes for the nuts on the butt are hexagonal, I burned them fixed on a long bar with several nuts).

The material for the guide was a 30x4 duralumin strip, the getinax was taken 8 mm from the instrument panel of the electrical cabinet. The drawing of the guide is made with a margin, because during manufacture, the course of the bowstring may differ, therefore, it is initially necessary to assemble the bow and measure the course of the bowstring, and then drill holes for attaching the deck. .

Fastening the shoulders to the deck through spacers (this is necessary because the shoulders have an initial bend, and the deck is straight) and pressure plates with three M6x25 "furniture" bolts (for one shoulder); Earrings for blocks are made of steel, like the blocks themselves, the weight of one block is ~ 65 g, if you make the same blocks from aluminum alloys, the weight will decrease to 25 g, I tried to make blocks by casting in a sand-clay mold, it generally worked out, but they were quickly cut by the rope.

The material was technically pure 99% aluminum, and the aging of the material could not be done, so I am content with steel, and I think where to get a duralumin blank of a suitable size (or maybe try using epoxy plastics). Block diameter 46 mm, eccentricity 11 mm. The string is made of 3 mm steel rope. in a PVC sheath, additional layers of heat-shrink tubing are put on at the points of contact with surfaces, I use loops to seal the ends and crimp them in the tube, like a clutch on a motorcycle, and the use of studs is necessary both for initial tension and for subsequent tightening during operation.

The bowstring is attached to the blocks through a pin which is inserted into the central hole, and opposite the hole with a dimer of 8 mm, which is opposite to the hole through which the axis of rotation of the block passes, under the groove of the block, two holes with a diameter of 3 mm are drilled through which the cable goes inside the block and is thrown onto the pin. The string enters the blocks through holes perpendicular to the axis of rotation of the block, and the loops at the ends are thrown onto the pin, one loop on the upper part, and the other on the lower part of the pin. It was through these holes that I cut aluminum blocks.

The stirrup is a fabric belt that is thrown around the deck, although you can attach a steel one to the deck, and by making it swivel you can use it as a bipod when shooting prone or from a stop.

When tensioning, I use a device consisting of a pair of blocks and a rope, when I cock it, the rope is thrown over the butt, and I hook the bowstring to the clips of the blocks, and pull the ends of the rope, a two-fold gain in strength, which is quite enough for not tiring shooting, I took the idea from the book of Yu. IN. Shokarev "History of weapons bows and crossbows".

A hunting crossbow is an excellent weapon for hunting food in the forest, as well as a means of survival in extreme conditions. It differs from a conventional bow in more accurate aiming, better striking power and ease of use due to the presence of a trigger mechanism. The advantage of such a weapon compared to the rest is that it can be made independently, it does not need to obtain a special permit, like a gun, and the simplest do-it-yourself crossbow can be made in a matter of minutes if time does not endure. Among the shortcomings can be noted the time spent on reloading, as well as a small distance for the sight on the target.

A homemade crossbow allows you to hunt any game, from small to large animals. The hunting crossbow has the following design:

• The base to which the rest of the elements with the guide bar will be attached. This bar determines the flight path of the bolt (arrow).
• Shoulders, or bow: determines the strength of the shot.
• The block that attaches the base to the bow.
• Trigger mechanism.
• Bowstring.

The base is carved from solid wood, but not heavy, so that the hands do not get tired of carrying weapons. The ideal options for the base material are beech and walnut. In the wild, there is no time to carve a beautiful base, but you need to try to make it as convenient as possible for yourself. The guide bar is a groove where the arrow will be placed. It should not create friction when the bolt (arrow) moves, therefore, after fixing it, it is necessary to go over it with sandpaper or a polishing wheel to grind its surface. You can make it separately using a metal tube cut in half, but in field conditions it is easier to cut a deep groove at the base of the structure. It is better if the bed and the guide are separated from each other.

Crossbow shoulders are an important structural part. A simple do-it-yourself crossbow has a classic bow design: the bowstring is statically attached to the shoulders, transferring the force of the shot from them to the arrow. To make a bow, you need to use flexible wood that will keep its shape without breaking from numerous bends: ash, maple, acacia. The shoulders are hewn symmetrically with a knife and in such a way that their base has a larger diameter in girth than the edges. At the edges you need to cut out fasteners for the bowstring. To attach the bow to the base, you need to make a block.

Usually the block for attaching the base and the bow is made of metal. In field conditions there is no such possibility, therefore the simplest model of a hunting crossbow may have a wooden block. To do this, you need a durable tree, ideally - oak. The block is attached to the base, then the bow is attached. Everything is connected into a single structure using self-tapping screws, nails, or a strong rope.

To carry out a shot, you need to make a trigger mechanism. In order to embed the trigger, you need to make a vertical slot in the base. A restraining bar should be attached above this slot to prevent accidental slipping of the bowstring.

Instead of arrows, like a bow, bolts are used here, which have a greater striking ability. They are made from durable and resilient material. The bolt must have a perfect shape, and the center of gravity should be in the first third of the shaft. All bolts must have the same length and weight, otherwise the result of the shots will always be different. Good bolts are made from fiberglass telescopic rods. The tip is made from a metal sheet cut with metal scissors. The tip is lubricated with epoxy glue and inserted into the cut at the end of the shaft.

Homemade speargun for spearfishing

There is an opinion that what is often erroneously called the "underwater crossbow" is rather a weapon that operates on the principle of a slingshot for fishing under water. The crossbow is not suitable for spearfishing, because the resistance of the water will not allow you to make a successful shot. However, it is possible to build a homemade speargun in the sense that it can be used to shoot fish from above, in shallow water, and underwater.

A homemade underwater crossbow is, in fact, a rubber battle gun. There is also a pneumatic weapon, but it is difficult to assemble it yourself, special skills and abilities will be required.

Underwater weapon consists of the following structural elements:

• Lever
• The basis
• trigger mechanism
• headband
• Rubber bands and hook

The principle of operation of the device is that the projectile pushes the harpoon and returns it back by means of rubber bands. The trunk is cylindrical or irregular in shape. Its task is not only to hold the guide, but also to resist the bending loads created by the rubber bands.

The underwater crossbow guide serves to stabilize the position of the harpoon. It is better to make it from an aluminum pipe, divided into two parts. One of them needs to be attached at the head of the gun, the second - at a distance of about 10 cm from it. The harpoon must pass freely through them. The headband is open or closed. In the first case, ring strands are attached, in the second, paired ones. When using ring rubber bands, the acceleration of the harpoon will be greater than with paired ones. An unbalanced rod power will either not generate enough force to project the spear, or it will put too much stress on the bow of the barrel. The strands must be attached on each side to the coil holder, secured with clamps. The second end of the strands must be passed through a special ring, it will be more convenient to shoot with it.

Depending on the size and power of the gun, the harpoon has a different length and thickness. The hooks on it are of the type propyl or sharpfin. The dihedral shape of the harpoon blunts less, and the trihedral one has a higher penetrating power. The device of the handle on a homemade crossbow is an individual matter, it may not be. If hunting for large fish is supposed, there must be a reel. It is most convenient to install the coil in the front end of the barrel.

The spring crossbow differs from the usual one in that the shot from it is carried out due to the elasticity of the bow. For the manufacture of such a model, you can use improvised materials: a spring mesh from an old bed, a spring processed by a grinder, shock absorbers from bicycle wheels. The spring of this type of crossbow can be located inside the bed, there can be two of them for each shoulder or one for both shoulders. The spring inside the stock is small in size, it is convenient to carry and use such a weapon in the forest. The spring can be used not only for tension, but also for compression, and by increasing the number of turns, you can adjust the tension of the bowstring. A spring projectile can be crafted by modifying your crossbow slightly with a normal device.

Now a very popular weapon is a crossbow. Despite the complexity, a crossbow can be made at home. In ancient times, it was used as a formidable weapon. Now the crossbow is used in sports at shooting ranges at short and medium distances. Nowadays, you can buy everything, including a crossbow. But it is much more interesting to do it yourself. For those who are skilled, know how to use machines and tools, this will not be a big deal.

Earlier we described how to do it, if you are interested, take a look.

For a crossbow, we need a wooden blank and iron.

These dimensions are the basis of our work on the manufacture of a crossbow at home.

Are you interested in medieval culture? Do you want to get a fashionable accessory, impress your friends with an exclusive souvenir? Decided to give an unusual gift to a loved one? Then you can easily make a magnificent crossbow right at home! It is this type of sporting weapon that is now rapidly gaining popularity, and people are happy to purchase it for themselves as a souvenir, a catchy design element. Why do you need a bow, what to do with it? Here are just a few of the most common ways to use a crossbow.

• An excellent solution is to use a crossbow on shooting ranges. Here is what an archery lover says: “You can arrange marksmanship competitions with friends, shoot at targets with pleasure, organize role-playing games. A bow will always come in handy for such a hobby, it will allow you to develop attentiveness, the ability to concentrate, and respond quickly.”
• Nowadays, crossbows are increasingly used for hunting. It is enough to load an arrow into such a bow and shoot accurately to become the happy owner of a partridge, a hare.
• Crossbows are also in demand as sporting weapons. There are professional athletes who regularly take part in competitions and constantly train. They also often make bows with their own hands.
• The bow can be made the central detail of the interior. Designers note its versatility: “The crossbow looks amazing in any room. In the corridor, he has a particularly formidable look, meeting everyone who enters the house. In the hall, he emphasizes the solemnity, focuses on the character of the hosts. In the bedroom, the bow hints at a passionate relationship, the power of love. In the kitchen, a crossbow might well be hung next to a hunting painting of game.”
• Increasingly, people are acquiring, making crossbows with their own hands to please their acquaintances, friends, colleagues with an unusual gift. Such a souvenir will be surprisingly original, will definitely come in handy and will evoke vivid emotions. It is especially appropriate to present a present to a man.

Now that you know how useful an onion is, how it can be used in many ways, it's time to familiarize yourself with the basic principles of its manufacture. How to make a crossbow at home, what you need to know so that it looks good, shoots well, can become a worthy weapon, souvenir and accessory? We'll find out very soon. The algorithm will help you, useful recommendations.

We make a crossbow with our own hands

You will need a good selection of wood. You can not take conifers, too old, dry branches. The crossbow consists of three main elements. It is necessary to make a high-quality trigger, stock and arc. Act strictly according to the algorithm, do not confuse the steps. You will succeed!

• You need to make an arc. It is advisable to take yew, hazel or ash for her. The board should be flat, without slant and knots. Make a thickness of about 2 cm. A piece of wood must be dried, kept for several days, and then cut evenly. The length of the arc is approximately 75 cm, the width can be made about 4 cm, the arc should gradually become thinner towards the edges. Thickness from the edges - 1.5 cm.
• Now you need to make a bed. For it, you will need hardwood, which is quite hard. Take a board of such a size and shape that it is convenient to hold it in your hands. Remember that from one edge you need to make a special groove where the arc will be inserted.
• It's time to machine the groove for the arc. You need to make a hole for fastening from a rope at a distance of ten centimeters from the cut groove for the arc. Now insert the arc into the groove, and then fix it there with a rope. Now attach the bowstring to the ends of the arc using the cuts made for this. Stretch the string as you would while shooting. It is necessary to designate a point that is as far away as possible. Now determine the optimal size of the crossbow - it should be equal to your forearm in length.
• A responsible task is the manufacture of the trigger for your bow. Previously, pin type locks were made. You will have to familiarize yourself with the distinctive features of such a mechanism. When you have already made a mark at the place of the maximum tension of the bowstring, you need to drill a hole through there. A transverse recess must be made in the box, in its upper part. Then fix the lever at the bottom of the crossbow. Most often, the axis is made of wood, and attached with wire.
• Now the bed and the lever must be folded together. Fasten the elements with a rope. The lever should move on the axis with minimal friction.
• Now you need to make a small pin, thanks to which the bowstring will be pushed out of the bow. The pin should be round, it is better to make it from oak. The pin will pass into the recess of the lock freely, without getting stuck due to the fastening. When the lever is raised, the plane of the bed and its upper edge should be equal. It is the pin that will push the bowstring.
• For the arrow, you will need to make a special chute. The recess extends from the top opening of the lock to the leading edge. The gutter must be laid at a shallow depth, approximately like a quarter of an arrow.
• Then it's time to work on the details. All elements must be walked with sandpaper. Sometimes parts are covered with egg white, after dissolving it in water.
• Secure the arc in the groove using a strong rope. See if the lock works well. All elements must be finally adjusted so that the mechanism is as strong as possible.
