Why Teak Wood Is The Best Choice
Wooden spearguns have a long history, since they have their roots in the arch and the crossbow. With the invention of vulcanised procedures and the rubber invention, rubber quickly found its place even on the oldest wooden spearguns.
Enthusiasm of mankind for new materials and new technologies pushed the usage of wooden spearguns for two to three decades to the side. Recently, however, they have started to become popular again and are experiencing a revival.
Wood is used for the manufacturing of spear guns because of certain good characteristics such as buoyancy, rigidity and also because of the possibility of using simple tools for designing it.
They are of different shapes and sizes. An essential feature of these products is that they can be corrected at any time, renewed or converted into other forms.
A well-made wooden gun usually has an imposing appearance and a beautiful shape of the wood. The downside of a wooden spear gun, however, is the length of time needed to produce it and that wood is a relatively more expensive material than other materials.
For all the above listed reasons, it is understood that the price for these products is higher.
As people always look for solutions in all possible ways, even the manufacturing of wooden spearguns is no exception.
Compromised solutions include making guns in a combination of a wooden body and plastic handle to make it substantially cheaper, as the handle production and its merge with the gun is one of the most demanding and time-consuming manufacturing processes.
In this way we get a new division of wooden spear guns.
On one hand we have classic "custom made" spear guns made entirely of wood, and on the other hand industrially manufactured or large mass production made wooden spearguns where the body is entirely or partly made of wood.
However, the head and the handle can be made from other materials, usually only screwed to the body. The manufacture of such guns is generally less complex and mainly much faster.
This can result in a lower market price. The question is whether the spear fishing enthusiasts will decide to buy a spear gun which is a kind of compromise or not.
It is for these reasons that a large group of fishing enthusiasts decided to manufacture the wooden spear gun themselves. In this way they have the possibility to incorporate their knowledge and love for designing the timber.
Types of wood suitable for making wooden spear guns: Let me first mention all the characteristics of the wood that are important here.
Specific wood density determines the buoyancy of the speargun. Rigidity of the wood is proven during vibrations and the curvature.
The hardness of the wood can cause problems during manufacturing and designing the gun.
Structure and density of growth rings determined by the growth rate of each wood type, specifically, stretching of the wood due to the effects of humidity, resistance to UV rays and the influence of sea water (salt crystals).
The best wood for all of these requirements is teak. It is a medium-heavy tropical wood which brings together outstanding characteristics for usage (since always) in nautics and thus is an excellent material for making wooden spear guns.
Teak is the most stable wood in terms of bending. It is very durable and resistant to high standards which exist in sea water.
Teak wood is greasy, and because of this it reflects water better than any other wood. It contains silicates, so it almost never parasites.
It has just the right amount of specific density, which gives it enough and can easily bear all the spear gun equipment. Despite the content of silicates which quickly takes the sharpness out of the carpentry tools, working with teak is pleasant for a carpenter, since it hardly raises any dust due to the content of the fat in the wood.
Listed properties of teak wood put it far out in first place regarding the suitability for the production of wooden spear guns.
The only negative feature of teak-wood is its extremely high price, which can be several times more expensive than other types of tropical wood.
Some manufacturers, therefore, use even other types of wood such as mahogany, rosewood, iroko, macore, wenge. The local choice can also be: larch or olive.
When manufacturing spearguns, combinations of different types of wood that are of different colours, can be very interesting. The manufacturer, however, should be attentive to the two properties, which may cause problems.
The combination of completely different types of wood when gluing strips of wood to the body of the gun can cause two problems:1. a change in the buoyancy of the spear gun, which requires additional balancing of the gun;2. gluing strips of different types of wood can cause problems due to different stretching of wood species. Humidity affects certain types of wood in very different ways, which may influence durability and consequently the lifespan of the spear gun.
It is also crucial to carefully select only the highest quality boards or prisms with as straight annual rings as possible, which run purely longitudinal.
When gluing strips of the wood to the body of the spear gun, it is essential to correctly turn the boards one against the other, depending on the rings.
Experienced manufacturers will also know that the boards can not be glued immediately after cutting but should be left about a week or two, so that any possible tensions in the wood can be relieved.
