Features of wire saws

Safety at work

To work with the bow product was as comfortable and safe as possible, the following tips must be taken into account:

• place the canvas only in separate slots located in the handle, and secure it in the required holes with special dowels;
• place the product at your chest so that the bowstring practically touches the body itself, and visually inspect the location of the canvas in the most attentive way - so that it becomes perpendicular to your line of sight;
• by precisely turning the handle, you can easily achieve an even position of the blade with teeth in special holes;

after the canvas is adjusted, carefully turning the arrow, twist the bowstring and stretch the racks in order to secure the canvas more firmly;
you should not sharpen or straighten blades for this kind of products without the help of a specialist if you do not have professional skills; it is best to immediately purchase sharp factory blades;

What is it and what is it for?

A bow saw can easily be defined as an outdated tool. But even if you have all the necessary set of power tools at home, there can be many situations when you cannot do without a hand-held bow saw. If we consider what the main purpose of this tool is, then it is worth noting that this kind of device is designed for accurate sawing of metal parts, as well as for working with wooden surfaces.

The bow saw can be used to make various dividing cuts with any type of wood. Do not forget that for a product intended for sawing wood, the way it is cut is unimportant - along or across. And also there is an opportunity to work with only one hand. This tool can be easily selected for cutting wood: in the longitudinal direction, as well as in the transverse and curly, even in the angular direction. True, for thick logs, it is better to choose a more serious tool.

If we compare a standard saw with two handles with a bow saw, then the following positive features should be highlighted in front of a classic product:

• the onion tool will allow you to make a much more beautiful cut;
• you will spend much less energy - sometimes it will be possible to work with a bow and a pair, which will not work when working with a saw in the form of a hacksaw;
• easy care.

Usage

On the market you can find a string saw of various modifications. Such a saw can be taken with you, just in case, to the forest, to nature, when it is not possible to use or transport any other tool. Often it is present in the set of a soldier, since it does not take up much space and does not add weight during the march.

With her help:

• harvest timber;
• clearing the shelling sector;
• used to remove obstacles;
• used for sawing plastic, wood and soft metal objects.

It is worth saying that the string saw belongs to disposable instruments, therefore, after the strings are broken, they are not repaired.

The resource largely depends on the indicators:

• metal quality;
• the number of turns;
• type of steel.

In the American version, the handle is equipped with a special clamp, thanks to which you can shorten the saw string if it suddenly breaks. The set always comes with an additional string.

Operating rules

In order to make a cross-cut with maximum convenience, wood blanks must extend beyond the edge of the fixed support. Experts try to start sawing using the thumbnail on the hand, which will hold the beam. As soon as the canvas "bites" into the material, it is carefully placed on the thumb itself. But for the best cutting accuracy, it is best to use special templates.

A bow saw for wood is perfect for ripping. For this process, the canvas must be secured at an angle of up to 90 degrees from a horizontal rack. The pressure here will be much less than with cross-cut, so this procedure will take a little longer.

If you need to make a curved cut, then you should stock up on a narrower blade so that its width is not more than 8 mm. Cloths for this kind of slots can be found with rectangular teeth and a significant divorce - up to almost 2.5 denominations of the thickness of the cloth itself. If you need to cut too thick material with a lot of knots, it is better to select the widest blade - up to 5 cm. It is better that it has a not very large divorce, but a weighty thickness. A cutout like curved or curved should not be made on such material.

Saws for any kind of sawing can also differ in the shape of the teeth. For a cross-cut, the teeth will be in the form of a regular triangle with equal sides. For cutting along - a slightly oblique triangle in the form of a wolf's tooth. You won't need to saw wood along the grain when hiking. Here, the primary task is to collect dead wood and cut it into a certain number of logs.

The effort that you have to spend on sawing will depend on the accuracy of sharpening and the correct setting of the teeth of the product. When sawing, the teeth will become dull - their edges will usually be rounded. The tip of the tooth will be most blunt. Sawing with such a product with blunt teeth is one torment. Before using the saw, it is visually carefully examined. Blunt teeth will immediately show a light strip along the edge; a well-sharpened tooth will not have such an edge.

It is worth considering in more detail how to properly sharpen this kind of product. If it is quite old and the height of the teeth seriously distinguishes one from the other, then you need to align them with a special file. The teeth are made even before the sharpening process, but after the setting. Sharpening of products is carried out using a file in the form of a small triangle. These are not very difficult manipulations, but they will require special patience. The tool blade will need to be clamped in a special vice. If you don't have one, the saw should be secured to some solid support - on the edge of a chair or stool.

Sharpening the teeth must be done alternately through the tooth, first on one side, and then on the reverse side. Part of the chamfer-type metal will be removed from the two edges of the tooth, with an arrangement at an angle of 60 degrees to the blade, which will fit the angle of the file itself, which has 3 edges. It is necessary to remove a little more metal from the tip of the tooth than from its own base. You can only press the sharpening tool with a sharp forward throw. The tool will go back a little more freely so that the file comes off a little from the surface of the canvas.

Chain saw with set

Although this saw is marketed as a garden saw, I think it is more suitable for hiking. It is compact and at the same time quite effective.

I previously read positive reviews about such saws, now I myself can confirm with full confidence - chain saws have earned a good reputation for a reason.

Since I am a well-deserved couch survivor, I have been interested in such camping items for a long time. One of my first purchases on Ali was a compact wire saw.If you know how to use it, then you can cut thin branches little by little, but even a small saw in my Swiss knife is more convenient and efficient. And not repeatedly came across the reviews - "the wire saw is garbage, but the chain saw, wow."

So, when I saw her in the garden tools section, I could not resist.

The saw arrived without branded packaging, just in a bag.

On the canvas there are traces of a powder that looks like shavings. As if she had already been tested.

The total length is 120 cm. The length of the sawing part is 71 cm (I call it a blade, I don’t know if this is correct).

Convenient plastic handles are located at each end of the canvas.

The handle is 108.5 mm long and 21.4 mm wide.

The 5.8mm plastic seems to be very sturdy.

A 200 mm thick nylon cord is threaded into the handles. Wire hooks are attached to the canvas, into which this cord is threaded.

The saw is called a chain saw because it consists of moving links. Interestingly, no traces of sharpening are visible. This means that the painting was done after sharpening.

The height of the tines is 3.9 mm, the width of the base is 4.6 mm.

The wiring is wide enough.

The thickness of the metal is 1 mm. Therefore, the thickness of the web is approximately 2 mm.

This is how the handles are in the hand.

The size fits my palm.

It's time to try the saw at work.

Dry apple tree trunk. Diameter approximately 8 cm.

In less than a minute I almost sawed it.

I was impressed with the speed.

And I must say, a few days before that, a thick trunk of an old apple tree was uprooted. And I very much doubted that I could handle it with my old hacksaw.

And then, seeing the effectiveness of the new tool, I decided.

First-person view.

In a thick barrel in this position, the saw jams. Past wire saw experience taught me how to get rid of this problem. Keep the canvas as straight as possible. If you are sawing a lot of trees, it is better to cut with two or pull the saw over a bow. I just spread the handles wider to the sides.

Barrel thickness approx 18-20 cm. I am impressed.

This saw can cut mature trees or chop up logs and can still fit in your pocket.

The saw weighs 183 g.

This is what it looks like compared to folding.

Foldable bigger and heavier. But it is more convenient to get it out and do small work for it.

So which one it is better to choose them for the campaign is determined by the range of tasks ahead.

I liked the saw very much, I have not seen it in our stores. As far as I know, similar saws of local production are sold in the Russian Federation. Maybe their quality is better, I didn't hold it in my hands. So, I will not recommend this particular saw, but this type definitely deserves attention from tourists, hunters and other fans of out-of-town recreation.

Finally, I would like to ask some advice - what is the best way to store and transport this saw?

Views

There are several original varieties of bow saws.

A folding bow saw, which is simply an indispensable accessory in hiking, where it is meant to independently build a resting place with the help of trees adjacent to the camp. Most often it is called hiking or tourist. Some manufacturers develop this kind of tool specifically for use in difficult conditions. The main feature of this saw is its foldable design. The product will actually fold and unfold quickly, and will not require additional tools or serious efforts for this.

• Hand-type bow saw for wood. Before you start working, you will need to carefully examine the product itself and personally find out that it does not have any defects on those parts of the racks that are made of solid wood, and that the canvas is intact.
• Bow saw for metal. Before purchasing a specific tool, specify what kind of material you will need to process.After that, it will already be possible to choose the most convenient form for work, as well as the length and width of the teeth, the speed of the device.

Rating of the best models

With their external similarity, bow saws will differ significantly from different brands. For example, there will be differences in almost the entire structure of this instrument - starting from a different design of a bow or a comfortable handle, ending with different fixation methods, as well as different tension of the bowstring.

Description

This tool first appeared in 1894, when it was used by surgeons to saw bone. The saw owes its appearance to Leonardo Gigli, after whom it was named. Its universal shape has made it possible over time to significantly expand the scope of the tool.

Despite the simplicity of the design, Jigli copes with the task no worse than heavier saws. True, it requires human efforts, since it is an exclusively mechanical tool.

The main technical characteristics that the buyer should pay attention to:

• type of metal;
• length;
• thickness.

Such a saw for wood consists of a twisted blade, the length of which varies in the range from 40 to 50 cm. As a rule, the thickness of the product is 0.5 mm. Such a tool fits anywhere, since it can be simply collapsed. The wire weighs up to 14 g, so it remains completely invisible even in a pocket. You can find many cheap options on the network, but they are of low quality and non-compliance with the technology by the manufacturer.

At the ends of the product there are hinges and metal rings, which are held by the user at the time of use. If the saw is designed correctly, then the rings at different ends should be of different diameters.The coils of the wire play the role of teeth, through which the wood is sawn through and under the action of the friction force. This string is very durable and is made of high quality steel. The saw is suitable for cutting foam glass. On more expensive models, diamond grit may be present.

Subtleties of choice

It is worth paying attention to the main features of choosing a saw blade

• When choosing or purchasing a bow saw, you need to especially look at its main parameters - whether you have chosen the right size of the blade, whether its stability, thickness, and method of fastening satisfy you.
• It is quite simple to choose the most suitable length of the fabric of the product - you just need to know the length of its frame. The parameters of the frame may differ - it is 350 mm long, and can also have a length of 500 mm or 700 mm or more. The length measurement system that will be used is also important - it can be in inches or centimeters. If the size of your saw is calculated in inches, then you need to select a blade for it, whose length is considered in the same parameters.

It is important what material the fabric of the product is made of. Several types of steel can be selected here

Saw teeth are often coated with a special Teflon coating to prevent corrosion or other negative processes that occur due to the influence of the environment around this tool.
The shape of the blade teeth is a special characteristic in the selection of the blade of the product. It can have a different shape - a trapezoid or a triangle, the "Kremlin" shape. An important feature of canvases for archery woodwork can be considered the fact that it will have a different number of teeth per 1 inch (or centimeter) of the canvas. This indicator will allow you to get a more accurate cut. The larger the number of teeth per 1 inch of the blade, the more beautiful the cut will be, and if there are few teeth, then the cut will be rough.

Jigli's Wire Saw

The jigli hand-held wire saw was invented back in 1894 by an Italian surgeon - gynecologist Leonardo Gigli. For the first time it was used during a surgical operation, during childbirth, it served for sawing bones. Later, due to its versatility, the wire saw began to be used not only in medicine (for amputation of limbs), but also in other areas, both in tourism and during the Second World War. There is official confirmation of its use by secret British intelligence officers.

Saw Jigli, is one of the most indispensable things during outdoor recreation. It is ideal for home use, camping, hunting, survival in extreme conditions, but just as good as a self-defense tool. It does not require a license, with the help of a wire saw, you can easily protect yourself from the attack of dogs, and more. This saw is an excellent substitute for bulky and heavy counterparts due to its compactness. Its full length is about 60 cm, of which 50 cm is the working part. One of the main positive qualities of a wire saw is its meager weight of about 20 grams. It is a steel bundle, which is twisted into a whole with wires of different thicknesses, each of which is wrapped on top with a thinner wire. At its ends there are two rings with a diameter of about 3.5 cm, they have been adapted for ease of use.

Gathering in nature, and taking a jigli saw with you, it is possible to cut down trees, bitches, logs with a diameter of about 15–20 cm. The cut comes out even from a hand saw, in contrast to the felling of an ax. Can also be used for cutting soft metals, plastics, rubber. Ideal for the "emergency kit" of a motorist, easily saws a tree that has fallen on the road. It is an irreplaceable helper for gardeners and summer residents.

Operating rules

Flexible and strong enough, such a saw is easy to operate and does not require special skills from the user.She can become an indispensable assistant in the country. Using the product is equally convenient for both women and men, and for this you do not need to have great strength or be prepared. It is necessary to work with any saw slowly and very carefully, regardless of whether it is mechanical or electric.

The user should know what not to do:

• heat up the working blade strongly;
• the cut should open, and not vice versa: this leads to jamming;
• put the string at an angle;
• make sudden movements.

The saw can easily cut a log by placing it on a support and working from the bottom up. Thus, it is possible to apply less effort, it is enough just to pull the canvas well over yourself.

If a branch is cut down, then the saw is held from above so that the user with his own weight can press on the string at the moment when it rubs against the tree. You can pull the string onto a branch and use it as a hacksaw, but in this case, be sure to maintain a uniform tension, otherwise you will not be able to use the entire resource of the product.
