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.
