For spearfishing, buyers are offered many guns. By design, they vary greatly. The most common are harpoon modifications. However, traumatic models that have high muzzle energy are also on the market.
If you are engaged in self-assembly of weapons for scuba diving, then it is more expedient to consider the harpoon modifications. The materials for them can be used in a wide variety. It should also be borne in mind that the lethal power of homemade weapons depends on the parts used. To assemble the model yourself, you need to consider the most popular devices.
Double skid model
With a double snake how to make the spearfishing gun itself? Answering this question, you should first think about the preparation of the pipe. Its length should be at least 12 cm, and its thickness should be about 4.4 cm. After grinding it, it is necessary to make a channel (a drawing of a speargun is shown below). It is cut, as a rule, with a width of not more than 0.5 cm. All this is necessary to place a ramrod there. After that, the runner is attached directly. The piston for him must be selected wide.
In order to fix the tube, you can use the hook. The clip in this case is wooden. However, it is possible to stick a patch on it. Then it is important to connect the sear to the gun. Only after this is it possible to install a war spring. It should be at least 3.5 cm in diameter. Winding for such models is rarely used. The tench with the trigger is the last to be installed.
Hawaiian weapon with metal pads
You can make a Hawaiian spearfishing gun with metal pads with your own hands without any problems. To do this, it is standardly necessary to prepare a pipe with a length of about 12 cm. Its edges can be easily turned on any machine. After that, the pads are already filled. From the front, they need to be installed at a distance of 2 cm from the edge. At the same time, they are attached 2 cm further at the rear region. All this is necessary in order to fix the barrel on the clip.
However, before this, many experts advise cutting a channel at the edge of the pipe. The sear in the gun can be installed only after lining. Then it is important to do the winding. After that, the tench in the gun will hold rather tightly. The next step is installing the ramrod. The trigger can be used from any machine. Compensators are not used in this case.
Two-spring shotgun
This type of do-it-yourself gun for underwater hunting is quite difficult. In this situation, the clip must be used wide. However, the work must begin as a standard with the search for pipes for the barrel. After this, the opportunity opens to connect the sear and clip. Many experts also advise making a winding at the edge of the trunk.
The linings are used if desired. Combustion springs should be attached directly to the axis. At the same time, they should not touch the line. After fixing the fighting springs, you can proceed with the installation of the feeder. In this case, the runner should be located near the clip. To do this, you can use the winding. Some also prefer a latch, however, you can consider the option with pads.
Pneumatic model with safety catch
Do-it-yourself pneumatic underwater guns can be assembled for hunting only if there are parts from the machine at hand. First of all, the barrel is removed. In this case, the clip is attached from the bottom with an indent of about 4 cm. Next, you must install the sear. Compensators are not mounted in all cases. In this situation, a lot depends on the type of fuse. The ramrod at the gun must be fixed at the base of the clip. The latch on the fuse is installed on the line side. In this case, it is necessary to watch the feeder. When changing position, it should not touch the fuse ring.
Rectangular Feeder
The device for spearfishing with a rectangular feeder resembles a modification with a latch. First of all, for the model, it is necessary to choose a pipe. Its minimum thickness should be 10 cm. After this, it is necessary to proceed to cut the tubule. Its thickness should be equal to at least 0.6 cm. Then there is the opportunity to make a patch. The clip in this case is better to install after the sear.
A fuse is used if desired. Further, to make a spearfishing gun with one's own hands, a rather dense winding is done. All this is necessary so that the return is not big. The axis for the weapon is most often selected steel type. The sear can be used aluminum. Compensators for the model are diverse. The feeder must be sharpened at the end of work. He should not hurt the runner.
Trapezoidal device
With a trapezoidal feeder how to make a spear gun? In order to assemble such a modification, it is necessary to begin work as a standard with a barrel blank. To do this, you can use a conventional pipe with a diameter of about 5.5 mm. It is more advisable to install the compensator after the clip. In this case, the mainspring must be selected with a diameter of about 2.3 cm. The feeder is most often used plastic. In order to securely fix it, you must use the latch. After that, the trigger mechanism is installed. It is best to borrow it from a pistol. If the mainspring is installed quite large, then at the base you can put the block.
Using plastic skids
With a plastic skid, how to make a spear gun? First of all, for this it is necessary to choose a good clip. In this case, the barrel can be made of pipe. Its length should be at least 80 cm. Rubber linings can be used for the barrel. The mainspring on the weapon is installed only after a whisper. First of all, the edges of the lining must be carefully cleaned to seal.
Additionally, it is important to take care of winding. In some cases, it is made of aluminum wire. Next, to make a spearfishing do-it-yourself gun, a small tench is set. The runner should not come into contact with it. The feeder is mounted above the fuse. In this case, the trigger mechanism is best borrowed from a pneumatic gun.
The use of hollow ramrods
With a hollow ramrod, a do-it-yourself gun for spearfishing (drawings are shown below) can be done using a conventional pipe. Lining for it is most often used rubber. In this case, the clip is selected depending on the diameter of the pipe. First of all, the sear is installed. To make a speargun with your own hands, then you need to fix the mainspring. In some cases, it is fixed on a small hook.
Winding in this case is most often used aluminum type. In this case, the sealing of weapons depends on the type of line. Its width should be at least 3.5 cm. In this case, we can hope for the overlapping of the sear. Compensators in such devices are used quite often. The trigger can be used from a traumatic gun. In this case, the latch should be L-shaped. Pads at the end of the work must be selected very carefully. The ramrod is installed only after fixing the clamp.
Compensator Weapons
It is quite difficult to assemble a do-it-yourself spear gun on the compensator these days. However, if at hand there are parts from a traumatic gun, then everything becomes much easier. First of all, you need to pick up a large block. Its width should be at least 6.5 mm. The channel should be made on it about 2.3 mm. In this case, the sear must be mounted on an aluminum winding. A hook should be fixed at the edge of the barrel. To install the fuse, you need to fix the clip. Its width should be at least 4.5 cm. The ramrod in this case will fit hollow.
The line for the weapon must be picked up quite long. Due to this, the compensator can be installed at its base. The feeder should be near the clip. It should also be noted that the compensator should not be in contact with the trigger mechanism. In this case, the latch should be located at a distance of about 2 cm. Thus, when the fuse is turned on, the compensator will not overlap.
Solid Line Model
Solid-line models are today considered the most common. They differ in their compactness. It should also be borne in mind that a wide sear in the models cannot be established. At the same time, various clips are suitable. In this case, the assembly of the gun must begin from the barrel. The screws must be attached from both the front and rear. After that, the clip is installed.
If you make it yourself, you should pre-calculate the length of the sear. It is also important to consider that the edges of the clip must be sharpened carefully. You can do this with a file. After that, the tench is set directly. Then you can start the fuse. Last of all, a ramrod and a trigger are mounted. When the capacitor is standing, then a war spring is installed.
Using aluminum winding
Homemade spearfishing gun with aluminum winding can be found quite often. Sealing such a winding provides a fairly high quality. You can start assembling weapons as standard from the barrel. At the same time, it is more advisable to select a clip of a small width. Thus, the winding will go down more closely. The sear for a weapon is best selected with three cloves. In this case, the fuse is selected separately.
Much in this situation depends on the size of the line. The compensator must be installed last. Additionally, it is important to pay attention to the trigger. It is quite difficult to make it yourself. Given this, it is more advisable to use parts from a pneumatic gun.
Double Lock Weapon
To date, these modifications are quite rare. In this case, the problem is that the fuse for the interlock must be T-shaped. It is quite difficult to get it nowadays. It should also be borne in mind that the trigger must be used from a pneumatic gun. He has small teeth, the fuse is not affected.
Overlay model
Pad models are the most common. In terms of sealing, they are today considered the best. It is necessary to begin the assembly of weapons with the preparation of the barrel. In this case, the clip is attached only after the sear. Directly pad should be fixed to the glue. Its thickness should be at least 2.2 mm. If the ramrod in the model is used quite long, then the pad should be stretched to the very clip. In the end, it remains only to fix the latch on the trunk.
Solid wound model
You can make a model with continuous winding if you prepare a pipe with a wide cage in advance. Many whispered for this purpose recommend using three cloves. Install the clip very carefully. In width, it should converge with a line. After fixing it, you can proceed directly to winding. At the same time, it should not be superimposed on the ramrod.
After completion of the work, it is possible to tackle the compensator. Then the feeder is attached directly together with the mainspring. Many experts in this situation advise using L-shaped latches. At the end of the work, it remains only to fix the trigger, which can be removed from any gun.
