In the process various works often there is a need for longitudinal cutting of logs or timber. For this, the most Various types equipment - from stationary sawmills to small installations, but these options cost a lot, and if you need to perform a small amount of work, then sawing logs with a chainsaw will be the simplest and most rational solution.

Benefits of using this option

First of all, let's figure out what advantages this sawing method has:

Important!
In addition to all of the above factors, one should not forget the low cost of the structure; the purchase of a stationary sawmill will cost several times more.

Overview of some options

Here are two of the most popular designs that provide best quality when working, and you yourself will determine what is more convenient and preferable in your case.

Homemade option

First, let's look at how to make a device for sawing logs with a chainsaw with your own hands.

The instructions for carrying out the work are as follows:

• It is best to use a frame from an old school desk or a square tube with a side of 20x20 or slightly larger.
• First of all, two clamps are made, these are elements 50-60 cm long, at one end of which a cross member is welded with two holes for tie bolts and a small protrusion in the middle for clamping the tire, an element of the same configuration is attached on top, the photo below shows ready-made elements, as you can see, everything is quite simple, and having at hand welding machine, you can make them very quickly.

Centuries and millennia pass, new materials and technologies appear, and wood, stone and metal, as they were, remain the main materials used by mankind for their needs. Products made from them surround us wherever we are, wherever we go.

Especially noteworthy is the tree, which creates an atmosphere of coziness and comfort everywhere. Metal and stone are colder and laconic, but wood is even warm to the touch. Therefore, the first two materials are used more often in the form load-bearing structures, and wood in the interior decoration, however, after bringing to the appropriate form.

Before properly sawing a log, you need to inspect it. If on outside Since there are no significant flaws in the wood, the processing can be done quickly and practically without loss of wood.

Logs must be sawn in such a way that the resulting materials have an equal density. And for this you need to remember that the wood on the north side of the trunk has a higher density than on the south. Sawing a log lengthwise begins with removing the slab, this part is removed from both sides of the tree to make a bar that will not roll.

We put the resulting timber on one cut side, and the other looks up, from which the sawing will begin. Now you can cut the remaining log into appropriate sawn timber or boards of equal thickness. As a result, we get a set of unedged boards, in which the raw edge (sometimes even with the bark of the tree) must then be cut off with a hand saw. Now the work can be considered completed.

How to cut a log lengthwise - disappointing realities

All of these recommendations are good for ideal logs, but, as you know, the ideal is rare. Basically, almost all logs have various shortcomings, and you have to adjust and invent ways of cutting in order to avoid wood loss and get as much as possible. quality material.

As in the previous case, before you cut the log lengthwise, you need to remove the croaker from it. For those who do not know, a slab is a board that has one sawn surface, and the other either gets partially processed or does not move at all.

After removing the slab, the next step is to make an unedged board, as already mentioned above. Ripping the log produces planks, but with rough edges. In the process, because the log is not ideal, it is necessary to periodically turn it over and identify it best options further use. Sometimes, for cutting one log, it has to be turned over 180 degrees several times in order to minimize defective boards.

If there is a possibility of obtaining good quality material from the other side of the log, you need to continue the process from it and so on until the wood is fully used.

Very often, after sawing, a bar remains, it can also be put on slats, boards or used in its original form.

Features of mechanisms for processing logs

Many private developers have a question: how to cut a log along a chainsaw? Experts recommend, for this operation, first of all, to fix the log and only after that carry out the processing. In addition, in order for the cut to be as smooth as possible, a good sharpening of the chain of this saw is necessary so that it does not go to the side, or buy a special chain designed for ripping.

In addition, it is desirable that the logs are not long, because it is very difficult to do something by hand from a long workpiece with high quality. Also in hardware stores, special nozzles for logs and a saw are sold, which are called a mini-sawmill, they allow you to work at home quickly and efficiently. The only drawback of such equipment is its high cost.

Act when used hand saw it is necessary in the same way as when processing with a sawmill. The slab is cut off and the remaining log is cut into longitudinal boards, from which the lateral raw edges are then separated. Only the main difference when working with a saw is the increased complexity, because you need to maintain a uniform thickness of the board when working with a saw that constantly tends to wobble, it is also just physically difficult to hold it in your hands all the time.

All experts agree that if there is an opportunity, it is better to take the material to the sawmill, where on professional equipment they will be processed with the least loss and extremely smooth edges.

More recently, a chainsaw was only used to cut logs across. Craftsmen could use it to make boards, rectangular bars, all kinds of wooden sculptures. For the townsfolk, this was not half the strength. Experience, skill and talent were required. Today, chainsaw manufacturers offer, as an addition, various attachments that have turned the tool into a universal device with which you can cut not only wood, but also other building materials, such as stone. In the article, we will deal with one question - how to cut a log into boards using an ordinary chainsaw.

To cut a log, you need a special attachment in the form of a metal frame, which is connected with two bolts to the body of a gasoline saw. The junction is the bolts that secure the working body (tire) inside the tool itself. The nuts must be unscrewed, the frame must be installed on them, the nuts that come with the frame must be screwed onto the bolts. They are wider, which increases the clamping area, increases the reliability of fastening the frame to the body of the chainsaw.

Such a nozzle can be made with your own hands from shaped pipe... The main thing is the accuracy of the frame dimensions.

Cutting technology

One frame-attachment in the process of cutting logs into boards is indispensable. Because it needs a support, especially when sawing the upper part of a log with bark. That is, when the operation of turning a log into a bar is carried out. An additional device is required, made of two boards.

Two boards 40-50 mm thick are fastened together so that they are in perpendicular planes. The device is attached to the log with self-tapping screws, from the ends it is propped up with additional stops from the same boards. In this case, the fastening is carried out so that the upper edge of the vertical board is below the upper edge of the log. That is, the distance between the edges determines the thickness of the cut slab.

It remains to install the chainsaw so that one part of the frame rests against the transversely installed board. This will be the support. The main plane of the frame will abut against the vertically installed part of the fixture.

The chainsaw turns on, the log is cut along with the set cutting thickness. The main task of the contractor is not to overload the tool with hand pressure. The saw, or rather the chain, will cut itself, you need to push it a little. After cutting the slab, the wooden device is dismantled, the log is rotated 90 °, the support installation is installed, the whole cutting process is repeated.

Attention! Wooden device used only for cutting slabs.

As soon as the log turns into a bar, you can cut it into planks without using a wooden device. Beam - lumber with rectangular section, it has four external smooth surfaces on which you can rest the chainsaw with the frame. You just need to press the frame against the cutting plane and move the tool along the workpiece. The frame has a thrust element located perpendicular to the entire structure, displaced across the cut. With its help, the thickness of the board to be cut is set.

To understand how logs are cut into planks with a chainsaw using a frame attachment, watch the video below.

Another variant

There are similar attachments on the market a large number of... All of them are suitable for sawing logs into planks, they all have a similar design. But there are also differences. The photo below shows attachments for a chainsaw, which does not require additional attachments or tools to work with. In fact, it is a miniature hand-held sawmill, which is based on a gasoline saw.

The design is complemented by guides and wheels that move along the surface of the log, reducing drag. There are two pairs of wheels, they are located on opposite sides of the workpiece. It is convenient, easy, plus - the quality of the cut material increases.

The attachment is attached to the chainsaw in the same way as in the previous case. The main requirement for work is to accurately position the saw so that it is in a horizontal position. And although the oblique cut is the same, it is more convenient and easier when the tool is aligned.

Homemade nozzles

Masters have long learned to do a lot with their own hands. There is a huge variety of frame structures on the Internet that allow a chainsaw to cut logs into planks. There is simple options manual type, there are large complexes of the bed, guides with the help of which the tool moves or the log is raised / lowered. One of them in the video below:

Please note that the structure is assembled from metal profiles, which makes it reliable and stable. At the same time, the machine (it simply cannot be called in another way) is equipped with mechanical gearboxes that simplify the processes of moving the workpiece barrel and the chainsaw. No effort with your hands, just twist the handle from the gearbox. In this case, the thickness of the boards is adjusted by lifting the log, and not with a gasoline tool.

Another option is a nozzle, which helps to make a cut not in a horizontal plane, but in a vertical one. The design is simple, but it is more difficult to work with it, because you have to make an effort to hold the chainsaw. In addition to the device, it is necessary to prepare a bar of metal or a board, which is attached to the log in the longitudinal direction. It is on it that the nozzle frame rests when cutting is carried out.

In addition, this option is more dangerous, because nothing holds the board to be cut. She can hurt her leg when she falls. So the process must be carried out carefully. The video below clearly shows how this option works.

Another installation, which the manufacturer called the carriage. For this, such a frame structure was made from a shaped tube and several wheels, which will give the device some mobility in terms of moving the workpiece along the barrel. They are also a kind of stops that do not allow the chainsaw to move from side to side.

In addition to the carriage, use the usual aluminum ladder acting as a guiding element. It is attached to the log with clamps for nails or self-tapping screws.

Please note that the width of the ladder must match the distance between the carriage wheels located at different ends. The ladder must be placed horizontally building level... Aligned underneath different thickness pieces of boards.

The prepared chainsaw with a carriage is installed on the stairs. Turn on the engine and push it with your hands along the workpiece, cutting off its upper part.

The process is better seen from the side. Here you can see a carriage with wheels, a ladder, a log lying under it, how the cutting process is carried out.

Fixture design of this type difficult enough. But out of many homemade options manual type it is better, more convenient, more reliable. Now it is possible to adjust the height of the cut horizontally, pre-setting the ladder along the horizon.

Generalization on the topic

As it turned out, an ordinary chainsaw is a universal tool. If you choose the right attachment, it can replace a large number of instruments. Moreover, some nozzles are easy to make with your own hands, since their designs can be found in the public domain. The internet is replete with variations.

Tree, along with natural stone, is one of the oldest building materials... Despite what is currently present at construction market a huge variety of all kinds of artificially created materials, wood is still in constant demand. Wood is versatile and available material, and not a single construction event is complete without its use.

The main raw material for the production of sawn timber (timber of various sections, edged and unedged boards, etc.) is a log - freed from branches and twigs, as well as from the thinnest upper part of the tree trunk. Logs can be used as a completely independent building material as poles, piles, masts, etc., however, in most cases, they must be sawed to obtain beams and boards. How to cut a log into boards, beams and other sawn timber will be discussed further.

Sawing a log can be done in different ways:

• manually, using a saw tool;
• on sawmills;
• on woodworking machines and specialized lines.

The price of lumber largely depends on its thickness and the amount of production waste.

In order to make the most rational use of the available raw materials and cut the log correctly, the woodworking industry uses special sawing schemes that reduce the percentage of waste and thus reduce the cost of the final product. Therefore, before you cut the log yourself, it would be useful to familiarize yourself with such schemes.

Tools and equipment for sawing logs

Depending on the total number of logs, their length, thickness and the expected quality of the future sawn timber, they use various instrument and specialized equipment. For a small amount of lumber at home, it is quite acceptable manual way treating trunks with chainsaws and conventional hand saws with teeth for rip sawing.

The sawmill is a fairly common type sawmill equipment... It is a woodworking machine with frame saws, designed for longitudinal cutting of a log to obtain edged boards and beams. The sawmills can handle logs with a diameter of 15 to 80 cm and a length of up to 7 m.

Sawing of tree trunks on circular saws is carried out using a circular saw. Such machines can be single-saw (single-disc) and multi-saw (multi-blade). Single-disk circular saws work, as a rule, with small and low-quality raw material. Multi-blade machines are designed for cutting large diameter round timber.

The most popular at present are the so-called band sawmills, both vertical and horizontal. As a cutting tool, they use a belt blade, put on the pulleys. Band machines provide high-quality longitudinal and mixed sawing of logs into boards and beams with a minimum amount of waste.

Lines for sawing wood are used in large enterprises in the production of lumber on an industrial scale. They provide high surface quality and precise geometry of the final product and have the highest productivity.

In addition to the above, in the mass production of sawn timber, other types of highly specialized sawmill equipment are used: debarking, edging, band-dividing and other machines.

Types and methods of cutting logs

Before cutting a log into planks and beams, it is important to choose the most optimal way sawing, which is determined by the dimensions, geometry and surface quality of the future sawn timber, necessary technical requirements, as well as the type of wood. According to the orientation to the tree rings of the trunk, the types of sawing can be distinguished. It:

• radial, carried out clearly along the radius of the annual rings;
• tangential, when sawing is performed tangentially to the growth rings, parallel to one of the radii;
• parallel forming, when cutting is carried out parallel to the direction of the grain (thus the minimum fiber inclination in the lumber is achieved).

Depending on the direction of sawing, there are several ways to cut logs:

• wobble sawing;
• sawing with bar;
• segment method;
• sector method;
• circular sawing.

Wash sawing is performed using several parallel cuts along the entire plane of the section of the log and gives at the exit unedged board and two slabs. Sawing wobble is the most in a simple way processing of logs and is used mainly for cutting small-diameter hardwood rounds, since other methods greatly reduce the width of the finished sawn timber.

Sawing with squared beams means sawing at the initial stage two-edged cant and side planks. The bar is subsequently sawn into edged boards the same width. Up to 60% of all raw materials are cut with bar. The disadvantage of this method is the need for the simultaneous use of two sawmills.

The above methods are basic. Special methods are used much less often: sector and segment. When sawing a sector, the log is first divided into several fragments - sectors, numbering from 4 to 8, depending on the diameter of the trunk. Then these sectors are sawn into boards in radial or tangential directions.

With the segment method, a bar is cut from the central part of the log, as a result of which two so-called segments remain on the sides. The resulting segments are then cut into tangential boards.

The circular sawing method is used when individual cutting logs and allows you to separate healthy wood from the affected. With circular sawing, after sawing off the next board or several parallel boards, the trunk rotates 90 ° around the longitudinal axis each time.

What you can't do with a chainsaw - with the help of all kinds of attachments, this tool becomes very multifunctional. Not sure how to cut a log into planks with a chainsaw? Now and not about this we will tell!

Chainsaw - a tool for all occasions

Most owners have no idea what possibilities are hidden in this seemingly single-function tool. It's about what functions, in addition to sawing logs for firewood, a chainsaw can perform in skillful hands... But just think - the tool is completely autonomous, you put fuel in the tank, and work wherever it suits you!

A wide range of work leads to a powerful, compact and safe gasoline engine, which has a very unpretentious "character" and the ability to work in the most difficult conditions. Another good thing about the chainsaw is the sealed fuel supply system, which, in combination with the diaphragm type carburetor, allows it to work in a variety of positions, except perhaps inverted. In addition, the designers provided reliable protection nodes from overloads and breakdowns in the form of a centrifugal clutch.

Take a look at the chainsaw from a different perspective - you are holding an amazing tool in your hands! After all, this is a universal drive for the most different kinds devices capable of not only sawing wood, but also cutting metal and stone, pumping water, drilling wells and even serving as a low-power engine!

DIY multi-tool

The most popular attachment, which is even produced by the manufacturers of chainsaws themselves, is the gas cutter attachment, which turns the chainsaw into an autonomous semblance of a grinder. The device of the nozzle is a bearing unit with a shaft, with a pulley installed at one end, which is driven in rotation by a V-belt. At the other end is a mandrel for attaching abrasive wheels. By changing circles, such a Bulgarian chainsaw will be able to cut stone, tiles, bricks and even metal. Of course, the circle is hidden in a protective casing, without which the work of such a tool would be pure water playing roulette - lucky or not!

Of course, there are a lot of people who would call this method extravagance, because you can buy a normal one and not have to worry about changing any attachments there! However, in practice, the idea is completely justified - high-speed saws equipped with such attachments work just as well as ordinary grinders. Of course, they do not compete with professional powerful tools, but they justify themselves on the farm. This device has two indisputable advantages - autonomy and saving money.

Another professional attachment that you can buy in specialized stores is the so-called debarkers. Their functions just correspond to the purpose of the chainsaw and, in fact, increase its capabilities - in addition to sawing wood with the help of debarkers, it can be processed, namely, cleaned of bark, growths and twigs, as well as cut grooves in logs, which is useful in the construction of wooden log cabins. and give the rounded surface a flat shape.

Debarkers are divided into disc and drum. The first ones are used to cut out recesses and mounting grooves, and the drum ones are used to remove bark from logs, they are also called debarkers. The device is a drum or cutter fixed in a bearing assembly. The device is set in motion by means of a V-belt transmission, for this there is a special pulley on the axle. Taking into account the change in the diameter of the pulley and the speed of the engine, you can also change the speed of such a tool for optimal processing of wood.

With the help of a chainsaw and the corresponding attachment, you can not worry about emergency water supply at home if necessary - you can make a pump from this woodworking tool in a few minutes!

Basically, the nozzle is a conventional centrifugal pump that attaches to the saw and is powered by the same pulley and belt. The principle of operation is the same as for everyone centrifugal pumps- one hose is lowered into the water, the second serves as a pressure hose. Before starting work, liquid is poured into the engine through the plug, which is necessary for the pump to "grab" the pumped-out water. The turbine, when rotating, creates a reduced pressure inside, due to which water is pumped out. The device is, in fact, the simplest, but imagine how useful it can be when Vacation home de-energized, and the issue of water supply needs to be resolved urgently!

By using special attachments a chainsaw can be turned into a drill or a winch and even into a boat motor capable of speeds up to 20 km / h with a fuel consumption of 1 l / h. However, these are already more rare cases, while devices for longitudinal sawing of logs, or, as they are called, mini-sawmills, are quite common.

How to cut a log into planks with a chainsaw - vertical attachment

First of all, it should be noted that no one sets himself the task of making a professional sawing of a log with a minimum amount of waste. For professional work the appropriate tool is also needed, however, the nozzle for longitudinal sawing of logs will allow you to solve a lot of minor problems... Suppose, for example, that your garden has withered old pear, and you just needed a few planks to fill a hole in the barn. Instead of putting the trunk of a tree on firewood, you can use the nozzle to get the material you want.

Devices for longitudinal sawing of logs are divided into vertical and horizontal. Most simple device is the first option: the adapter is attached to the bus at its base, and with the help of the guide bar, the straightness of the adapter movement is ensured. This whole structure is attached to the board, which is a stop for cutting and at the same time a guide. The accuracy of such a device is not high - it can be used to cut rough boards or give a log an uncomplicated square shape, however, appropriate tasks are set for such a device.

How to cut a log lengthwise - we cut horizontally!

Much greater cutting accuracy is provided by the horizontal structure, which is a rigid frame attached to the chainsaw bar in two places - at the base and at its end. The attachment points can be shifted to provide the required kerf width. Of course, such a device is intended for small logs, the diameter of which will not exceed the length of the bar.

Using the guide element, you can set required thickness boards. The most difficult thing will be to make the first horizontal cut - in order to get an even cut of wood, you need to attach an additional guide frame to the log, which will serve base surface for emphasis. At the subsequent stages of dissolving the log onto the boards, the flat surface of the previous saw cut serves as a surface for an emphasis and a guide.

It is quite easy to work with such a structure. Before sawing a log lengthwise, it must be well secured along its entire length - the less it vibrates, the smoother the cut will turn out... To avoid jamming the chainsaw bar, small wedges are constantly inserted into the cut to prevent clamping. It should be noted that no matter how hard we try, there will be a lot of waste compared to a conventional sawmill. First, give the log a square shape by sawing upper layer from all sides, and only then proceed directly to dissolving the logs onto the boards.

It will not be difficult for craftsmen to make their own nozzles of this kind to work with welding and metal - the corresponding schemes on the Internet are not uncommon, and from the material you will need several square hollow pipes, nuts and screws.
