Now it has become fashionable to hunt with a bow and crossbow.Although in our country it is prohibited, but still you can shoot at targets, practicing in this difficult business. You can make a crossbow with your own hands at home for training. After all, good models from well-known companies are very expensive. A homemade crossbow can be made "by itself." It is worth remembering that if the weapon is more than 20 kg, it is considered a cold weapon. Therefore, when creating a crossbow, it is worth considering this important nuance.
The crossbow has many components:
bow;
bed;
the trigger mechanism;
string;
in some modern models there are blocks at the ends of the bow.
The main material from which the crossbow is made isthis is a tree. From it they make a bed and an onion. The trigger mechanism in the powerful specimens is ground out of iron. And those in which the tension force is less than 20 kg, you can make a solid wood, it will withstand. Also used for onions are spring metal and various composites.
First, let's look at how easy it is to make a crossbowwith our own hands, and start with a simple form. This is a standard design of ancient weapons, and it can be used not only for shooting, but also as a spectacular piece of furniture, hanging on the wall.
To create a crossbow, you need to choose:
oak;
ash;
acacia;
maple;
poplar.
All these rocks are dense enough to withstand the huge loads that will affect the bow and the bed of the crossbow.
To the weapon fired long and powerfully, its materialmust be properly dried within a year. Cut the necessary trunk or branch, both must be painted over. To do this, you can use any glue, paint or varnish. If you close the logs in this way, moisture can not quickly leave the workpiece, so the wood will dry more slowly and evenly. So the material does not form internal cracks, and a crossbow made by oneself at home will serve for a very long time.
After that, the log is put in a dry place, whereit will not be sunrays. So it should lie a year. After a while, the bark is removed from the billet, so it dries a week. Then the log is sawn in half. So it is still a week, only after that you can start creating a crossbow.
Knife.
Saw.
Plane.
Sandpaper of different granularity.
Joiner cutter.
Chisel.
Drill.
On the workpiece, choose the side in which the annualthe tree rings are thinner. This is the northern side, the fibers on it are denser than in other parts. This is what we will use, creating a crossbow with our own hands at home. From this part you need to make a bow.
Plan the middle, from it in both directionsput off about two centimeters, marking out the part that will be squeezed into the box of the crossbow. This will be the thickest place of onions. From it begin to cut the material, moving gradually to the edges. String the workpiece gradually on both sides, while checking, until it begins to bend slightly.
After that, you need to take a strong rope, makeat its ends are loops. It will be a test string. It is necessary to check the bow tension. It is very important that his shoulders bend evenly. Wearing an improvised string and pulling the bow, you can see where to shoot the material. They are marked, neatly cut with a knife. So you need to continue until the product will not bend evenly on both sides.
Very often the material comes across knots:some can be seen immediately, others can be opened during the processing of the material. The more dangerous they are, the fact is that because of them, chips can be formed. Therefore, you need to handle such places with a well sharpened knife. If there is no confidence or experience, it is better to tinker a bit longer and sand it with sandpaper. You can also use the file for this purpose.
When the onion is ready, it is postponed and proceededmanufacture of a box. First, choose where there will be a trough, along which the arrow will fly, make this place perfectly smooth. It is from him will depend on how accurate the crossbow will shoot. To understand everything, it is better to look at the drawing of the crossbow. How to make his bed, here is detailed. After that, cut the trough for the required length. Usually it is about 30 cm. Then make a recess for the bow and trigger mechanism. They are conveniently cut with a chisel and carpenter's knife.
We examined in detail how to make a crossbow with our own hands. A master class with drawings, we hope, will help to understand all the subtleties.
This is an ordinary medieval model. Now we learn how to make the same weapon, only the modern model.
Such a device is much more difficult to make for himyou need a lot more tools than for the usual. So, we create a crossbow with our own hands at home from fiberglass. This material is ideal for making onions, because it is biting and light at the same time. It can be cut from a single piece of fiberglass 1 cm thick or done by yourself. If not too lazy to tinker, it is better to make yourself.
It is necessary to take fiberglass or Kevlar and cutstrips. They need from 30 to 40. In general, it is better to try everything by experience. These strips are glued with epoxy resin so that everything solidifies when solidified. You also need to think about how to put all this "sandwich" under the press. It is best to use the boards between which to place the shoulders, to clamp all the clamps.
In epoxy adhesive there should be less thickener,than usual, in the range from 8 to 10%. Everything freezes in 24 hours, but if the room is cold, time can increase. When everything is frozen, the shoulders are finished, cutting the sticking edges with a knife and sanding with sandpaper.
To do this, take a board with a thickness of at least 4see Mark, where there will be butt, handle, trigger and anchorages for the shoulders of the bow. In general, everything is according to the drawings. After that, you need to drill all the necessary holes and cut.
They can be made of aluminum.It is better that they were on the bearings. Perfectly fit the middle parts of the wheels for roller skates. They are strong enough to withstand heavy loads, in addition, their size is ideal. Axes for them are needed in 5 mm thick. You can take them from the videos or do it yourself.
The fasteners are made of sheet steel or the likedurable material. You can also make the ends of the onions thicker before filling them with epoxy resin, to install the blocks, in this case, no attachments will be needed.
After that, the crossbowhands at home, you need to install the trigger with the trigger and the boom holder. In general, all parts are connected with bolts, must-have washers are used. They will allow more tightly twisting, without damaging the material.
In block crossbows the bowstring is longer and stretchesdifferently. It seems to cross over, and with the tension this system allows you to give the arrow twice the energy for flight than in the case of a conventional crossbow with the same bow.
In powerful block models the string isa steel cable, only it is capable of withstanding a huge sharp pressure when shot. In crossbows, whose power is not more than 40-50 kg, it can be weaved from kapron threads.
In this way, you can make a string for both a recursive and a classic crossbow. Just their length will be different because of the features in the designs of both models.
Take a board length of the planned bowstring,drive two pegs, which are wound around a nylon thread. When the thickness of this long oval becomes 5 mm, it is wrapped, making a gap of 2-3 mm between the windings. Near the pegs you need to braid without gaps, because there will be loops for a hook.
Concerning the bowstring, it can be said that ifmake it too thick, then the strength of the crossbow decreases. However, thin can tear. So in this case you need to choose an intermediate thickness. It is better to study similar sports models with the same tightness and make a string of their thickness. When this is done, the two halves are joined and wrapped together. Again, near the loops need special care. Then wrap the middle, where the bowstring will engage and push the arrow. This place is also done carefully, because it will be provided with a force of friction of enormous power. All the cut edges of the threads need to be glued with glue. This will make them more dense and monolithic.
This article presents the drawings and descriptionhow to make a real crossbow at home. This is not so difficult, especially if you make wooden weapons. If the product is made for hunting in order to achieve enormous power, then you should choose a block model. Its design is a little more complicated, you may need a machine for making some parts.
