Advice 1: How to make a crossbow drawing

Interest in medieval culture is forced to remember not only the old costumes and books. Many revived old technology to make exact replicas of household items and weapons. Along with historic swords and bows was revived and a crossbow. Shooting from it became an independent sport. Some types of crossbowand applied as a hunting weapon.

A crossbow consists of three parts. This is the box, bow and trigger mechanism, he's castle. Manufacturer of crossbowand the most ancient of the construction, start with arc. It depend on the settings of the other parts. Select the Board. Arc fit ash, yew, hazel, Rowan. Conifers are not suitable. The Board should be dried well and survive. On should not svilevatosti, ROE and knots. Cut a piece with a length of 70-80 cm, a width of 3-4 cm and a thickness of about 2 cm Treat her plane so that the arc was uniformly refined to the ends to a width of 1-1,5 see
Fabricate the box. It is made of hardwood having sufficient hardness. It can be maple, birch, beech and even oak. Keep in mind that the crossbow when firing is not pressed against the shoulder and had no butt. So make the bed in the form of boards, which is comfortable to hold in hands. In the front part of the bed, make a groove into which should enter the Central part of the arc.
At a distance of 8-10 cm from the groove make a hole for rope attachment of the arc. Temporarily fasten with a rope the arc in the groove, wrapped a rope around the arc and threading it into the hole of the bed. Attach the ends of the souls of the string. For this purpose, it is necessary to make small notches with a knife. Pull the bowstring as you pull it during the shooting (as far as allows you your strength and the strength of the arc). Make a mark on the box in the place where in this moment is drawn bowstring. Remove the arc from the couch, and continue its processing. From the mark of a bowstring back for a distance equal to the length of your forearm. Saw off the workpiece.
Make trigger mechanism. In this design you can apply the ancient castle of the so-called pin type. Drill a through hole in the bed on the place marks of the bowstring. In the upper part of the bed, make a cross indentation on the depth of the stringer. In the lower part of the hook lever of the hinge according to the drawing. The axis of the lever can also be made of wood and fixed by passing through it two pieces of wire. Insert the axle in the bed, thereby securing the lever. Fix it, pierced on two sides by pieces of wire. The holes for the wire, you can drill or burn. The latter method is more in line with historical technologies. A small protruding wire ends wrap around the axle.
Put together the box and the lever. Lock them in this position with a clamp or rope and, using the existing hole in the bed, drill out the lever blind recess to a depth of 1.5-2 cm, Remove the clamp. Check how loose the lever on the axis. The friction should be minimal.
From oak or beech with a knife cut round the pin so that the diameter it was slightly smaller than the lock opening. The pin should be free, frictionless and hooks, to enter into the hole, relying on the trigger. Pin length should be such that at full lift lever top edge is flush with or slightly above the top plane of the bed. The function of the pin is to push the bow out of the groove.
Fabricate chute for a bolt (arrow). Penetrate it from the front edge of the bed to the top of the lock opening. Depth of gutter should not exceed a quarter of the diameter of the bolt.
Perform a final processing of wooden parts. Abrade them using sandpaper. They can be lacquer coating of albumin (egg white diluted in water) or to wax.
With a rope to secure the arch on a bed. Check the correct operation of the lock. Pushing the lever up pin must be confident to push on a string.
Crossbow medieval technology were made without a measuring tool. The master did it on the physical parameters of a particular arrow.
Useful advice
To the lever spontaneously fell down down, you can make a loop in the leather belt. It will fix the lever in a horizontal position.

Bolts (arrow) for the crossbow made from any species of wood. The tail can be made feathers, pieces of skin. In some cases it does not. Bolt length should be such that in the cocked position with the feathered end was at the level of the locking edge of the gutter, and cap-weighting began behind the front edge of the bed, as it has a larger diameter than the rest. The design of a tip can be any, depending on the purpose of the arrows.

Advice 2: How to make the trigger mechanism of the crossbow

The crossbow is a missile weapon in which the projectile is used arrow. Invented crossbow was many centuries ago. Since then his form has changed, weapons have become more modern. However, the principle of operation and design of the crossbow remained the same. The most important subsystem is the crossbow trigger mechanism. From its simplicity and reliability depends on the quality of the shooting.
How to make the trigger mechanism of the crossbow
You will need
  • Plates of steel or brass rod of the drum, hacksaw, wood saw, file, fasteners
The trigger mechanism of the crossbow is very simple, which is key to the reliability of the device. The purpose of the trigger mechanismand to make the descent of the string smooth and easy.
Bed crossbow sawed into two pieces to place between the parts of the trigger mechanism. Of steel or brass cut out two plates. Plates should be uniform in size. Form of does not really matter, as long as they fulfilled their function.
Fabricate the drum. It will keep the bowstring, and the drum is held by the ledge of the trigger. When you press the trigger the drum is released from the barrier and begins to rotate. The string comes off the drum, the arrow goes into the target.
After you fire a shot, pull the string back to its original place, the drum engages the lug for the string and is rotated to its original position. Triggered spring-loaded trigger, he gets into the groove of the drum. Now the drum is rigidly fixed and does not rotate. The string is put on the tabs drums, crossbow ready for another shot.

Advice 3: How to make a crossbow

A crossbow is a type of small arms, which operates on the principle of a bow with arrows. To purchase and use a crossbow does not require a special permission and registration. To manufacture such weapons out of wood will not be difficult for experts of carpentry.
Homemade crossbow

Where to start making a crossbow

Before self-production of crossbow should be determined with a device of this type of weapon. Its main elements are: the trigger, the bowstring, bow string, sight, tension mechanism and wooden base, which is called a bed.

Of course, crossbow, hand made, will be very different from factory design. But the principle of operation is similar. To start you will need to make the base of the crossbow. The base is the main element of such weapons. It can be made from such woods as birch or walnut. The thickness of the workpiece must be not less than three inches. After creating a need to draw on it the shape of the ground, and then cut it out.

As for the bow, for its manufacture, you can use the arc from the old sport bow (if you have). For connecting the stock of the crossbow and bow will need to connect the bow to the ground. However, you can use another option. It involves making a metal frame. It will house a bed and bow.

How to make a bowstring

The string should not have a high degree of extensibility. Otherwise, homemade crossbow very quickly cease to perform their functions. So, the best material for bowstrings will be Dacron or fastflight. Wrap the threads previously put between nails. Don't forget to make a loop for putting on string. Pull the string it will not work without stirrups, which in turn can be made from steel wire or rope.

One end of the cable or wire, attach to the base of the crossbow. And at the other end of the lock handle. Also will definitely need to adjust the tension level of the closed string after it is fixed. This can be done directly on the crossbow.

The trigger and arrows

After adjusting the tension of the string, you can go to the manufacture of the trigger. The role of such a mechanism will be a wooden lever, which will require a carefully integrated in the crossbow. Then it is necessary to mount the sighting device. Flies can be used for the mechanical sight.

Arrows for homemade crossbow can be made of ordinary planks of wood, and then planed. If you want the arrows to be durable, it is not necessary to hammer in nails. Otherwise, when the target arrow may break.
