The direct purpose of a manual jigsaw on wood is to carry out carpentry and construction work. It is immediately worth noting that this device can be used not only for working with wood, but also with materials such as plywood, fiberboard, polystyrene or plastic. In addition, the presence of such an assistant will be relevant not only for home masters, but simply for residents of private homes.
What is a jigsaw
Most often, a manual jigsaw on a tree is used for the same purposes as a conventional saw, that is, for cutting a tree trunk. However, unlike a saw, it is also capable of making a fairly acceptable longitudinal cut, and more importantly, it is possible to draw curly lines. This quality has led to the fact that the tool is often used when applying patterns to wood products. Saws for a manual jigsaw on a tree initially differed little from a regular saw. The main difference was in the design, as the file was pulled between the wooden holder. However, she quickly acquired her final changes. The dimensions were significantly reduced, and the number of teeth, on the contrary, was significantly increased. As for the design, they all have similar elements.
Firstly, a wooden handle. Secondly, the presence of a clip for the file. Thirdly, the metal case on which the clamps are attached, where the file is inserted. The last element is the file itself for a manual jigsaw on wood.
Jigsaw blade
To date, there are two main types of blade that are used to make the file. The main difference between them lies in their shape, as well as in the location of the teeth.
The first type is a straight double-prong web. Using it, you can quickly make, for example, a straight cut. The total length is about 130 mm, and the working length is 85 mm. This type of file is well suited to deal with sawing not only wood but also plastic.
Canvas for a manual jigsaw on wood can be spiral type. The curled shape of such a file is great in order to create a variety of curvy lines or circles. In other words, it is more suitable for applying decorative thread than for cutting.
Brief Assembly Instructions
Today there are two types of jigsaws that you can assemble with your own hands. The first type is manual, and the second is electric. Hand models are considered classics, because their description is presented below.
It’s worth mentioning right away that to assemble a hand-held jigsaw on wood with your own hands, you will need an old sewing machine, as well as a file. The sequence of work is as follows:
- you need to carefully unscrew the bolts that hold the needle and remove it;
- since the model will be manual, it is necessary to remove the drive shaft;
- it is also necessary to remove the protective model from the machine;
- after expanding the hole that holds the needle to such a size that you can insert the file;
- a slight inconvenience is that you have to cut the length of the file to the length that the needle had;
- the top and bottom of the product are grinded, after which it can be inserted into the machine.
The instruction is quite simple, almost anyone can make a manual jigsaw on wood.
The advantages of the tool over the saw
Despite the fact that both the jigsaw and the saw are capable of performing the same function, the first has a number of advantages.
- When cutting with a jigsaw, the surface remains smoother. This is especially important if further processing, grinding or polishing is planned. The saw leaves a rather coarse cut, which is why it is necessary to carry out processing several times.
- The manual jigsaw on wood has the ability to quickly change the blade, if necessary. In this case, the web tension does not have to be changed.
- It is important enough that safety when using a jigsaw is much higher. The teeth are small, which means they can’t do much harm. The saw, on the contrary, has rather large teeth, and therefore if it comes off, it is possible to damage both clothing and skin.
Jigsaw operation
It is worth saying that using a jigsaw is very simple, however, to achieve a high-quality result, you need to know a few simple features. At first it is very important to correctly and tightly fix the canvas in a jigsaw. To do this, untwist the clamps into which the file is inserted. Insert the product with the teeth down. Naturally, the clamps are screwed back after this. In order to conduct work more efficiently, it is recommended to find a fixture that will hold the workpiece during operation.
The choice and price of a jigsaw
In order to buy a quality tool, you need to pay attention to several things. The shape of the jigsaw itself plays a large role. For example, a rectangular and pointed shape will be suitable for fulfilling completely different goals. Another important factor for a convenient tool is weight. Since the jigsaw is manual, and it is often necessary to work with it quite a long time and at the same time very carefully, the hand will quickly get tired if the weight is too large. Therefore, you must buy small and lightweight fixtures. In addition, it is worth paying attention to the shape of the handle, so that it is convenient, it should be anatomical, that is, in the shape of a hand.
How much does a wood jigsaw cost? Naturally, the cost will depend on the quality of this tool. You can buy a model for about 150 rubles, but using it will be very inconvenient, especially during long work. The cost of some sets reaches 2000 rubles, but they are very convenient and last longer. Often, these kits are sold in separate containers, so storing them is easy.
