Chainsaw attachment for cutting logs onto boards
Options for sawing logs on boards with a chainsaw
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, it was not half the strength. Experience, skill and talent were required. Today, chainsaw manufacturers offer various attachments as an addition, which 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.
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 are simple options for the 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 raising 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 on 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 profile pipe 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, a conventional aluminum ladder is used 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 staircase must be placed in a horizontal plane with a building level. Align with pieces of boards of different thickness placed under it.
The prepared chainsaw with a carriage is installed on the ladder. 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.
The design of this type of device is quite complex. But of the many home-made options for the 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.
Special nozzle
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 a profile 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 made of two planks will be required.
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 made 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 device.
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! The wooden device is 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. A bar is a lumber with a rectangular cross-section, it has four external smooth surfaces on which you can rest a chainsaw with a 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 cut board is set.
To make it clear how logs are cut into boards with a chainsaw using a frame nozzle, watch the video below.
Another variant
There are a large number of similar attachments on the market. 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 located exactly.
Generalization
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. over, some nozzles are easy to make with your own hands, the benefit of their design can be found in the public domain. The internet is full of variations.
Debarkers
By design, debarkers are divided into drum and disc. The first ones are mainly used to remove bark from logs (cutters), disc cut out mounting grooves, cups, grooves, etc.
The working part of the devices consists of a drum or cutter fixed in a bearing assembly. Like most chainsaw attachments, the debarkers are driven by a V-belt drive. On their axis there is a driven pulley for this. By selecting the diameters of the pulleys and changing the engine speed with the help of the accelerator, it is possible to obtain the optimal rotation speed of the working tool, providing the necessary processing parameters.
The figure below shows debarkers with different shapes of the working tool: groove cutter (a), flat planer (b) and spherical (d), curly cutter (c).
Pump
The principle of operation of this nozzle for a chainsaw is similar to the principle of operation of all centrifugal pumps. A hose is connected to the central fitting (1), which is lowered into the water. A pressure hose is connected to the fitting (3). Before starting work, water is poured into the plug (2), which is necessary for the pump to start pumping. When the turbine of the pump is driven into rotation, a reduced pressure is created in the suction pipe, sucking in water, which is then discharged through the pressure hose.
The rotational speed of the auger during drilling should be relatively low, therefore a gearbox is used to reduce the speed. It can be made in the form of a V-belt or worm gear (preferable).
Gas cutter attachment
Its main unit is a bearing unit with a shaft, at one end of which a driven pulley is installed, driven by a V-belt, at the other. mandrel for fixing cut-off wheels. Depending on the brand of the latter, the gas cutter can cut metal, stone, brick or tile. The end part of the nozzle is made with a groove for attaching it to the saw.
Winch
Its tractive effort depends on the power of the chainsaw and can reach 1500-2000 kg, and with an additional block. and even more. To perform its functions, the winch must be equipped with additional accessories: a diverter block to increase tractive effort and change the trajectory of movement, hooks, anchors, sling straps for securing to a tree trunk, rock, ground or car.
Chainsaw attachments and accessories
Several factors contribute to this wide range of work performed by chainsaws. First of all, it is the presence of a powerful (in relation to its weight), compact, reliable and unpretentious gasoline engine, capable of operating in the most difficult conditions. A diaphragm carburetor and a sealed fuel supply system allow the saw to work in different positions, except perhaps for a complete overturn. The successful design of the centrifugal clutch reliably protects the systems and units of the chainsaw from overloads and breakdowns. The simplicity of power take-off is also important; it is easy to connect any device to the output shaft of the tool. And, finally, the advantages of the chainsaw include autonomy, which allows you to use it anywhere.
Keep in mind, however, that hobbyist chainsaws are not designed to be used all day in an intensive mode.

Rip saws on logs
(mini sawmills)
Device for vertical cutting of logs. The simplest is the device for vertical sawing of logs, shown below.
It consists of an adapter (1), which is attached to the bus at its base, and a guide (2), which sets the straightness of the adapter movement. The guide is installed on the board (3), which in turn is attached to the sawn log.
The main purpose of this chainsaw attachment is to keep the tire moving in a straight line. With its help, you can not only dissolve a log into two or four parts (quarters) or cut a bar out of it, but also saw it into boards or beams. However, in the latter case, you will have to rearrange the board with the guide every time, and you will not be able to achieve great accuracy when cutting. The unsecured end of the tire can move to the side, as a result of which the constancy of parameters and full parallelism of the sides of the beams or planks is unlikely to be achieved.
Horizontal cutting device. With the help of the device shown in the photo below, logs are cut in a horizontal plane. In comparison with the device for vertical sawing, it has increased functionality and accuracy, allowing you to cut boards or beams of the same thickness.
A device that attaches to the bus in two places. beginning and end. has a frame structure that ensures the rigidity of the device. The attachment point (1) can be displaced along the tire. This allows you to set the required kerf width (according to the diameter of the log). within the bus length. The guides (2) can be installed at any distance from the bar, thus providing the required thickness of the cut beams or boards. The first horizontal cut is carried out using a guide frame (3) mounted on the log and serving as a base surface for the guides (2). Subsequent cuts use the flat surface (4) from the previous cut as the reference surface. In the process of work, in order to avoid clamping the saw, wedges are inserted into the cut, preventing the narrowing of the cut.
If it is necessary to cut logs with a diameter greater than the length of a standard bar, use a more complex device, which uses a long bar. In this case, the saw’s native lubrication system does not provide high-quality lubrication of the entire chain, therefore, it becomes necessary to install an additional system consisting of a tank and a hose supplying lubricant to the end of the bar. To ensure the supply of oil by gravity, the tank is placed on a rack above the tire.
Vertical nozzle
The simplest nozzle used to produce a rough board. On the board, which serves as a guide during the sawing process, a tire is attached with an adapter fixed at its base. It is clear that such a simple device for sawing logs with a chainsaw into boards will not be particularly accurate, but you can still get a board, for example, for a fence with it.
Additional accessories
Most often, additional devices are used for sawing logs with a chainsaw into boards.
- Debarker. Chainsaw attachment, with which you can sand a log, clean it of knots and build-ups, or cut grooves in the log.
- Cross and longitudinal cutting attachments. It is this device for sawing logs with a chainsaw that is used to make boards.
- Gas cutter attachment. An attachment that allows you to turn your chainsaw into an almost complete angle grinder. At least for home purposes, it is perfect.
In fact, there are a great many such nozzles, but we will not delve into them, since we have already listed above what we need for work.
Do-it-yourself sawing logs with a chainsaw on boards

The most commonly used material for private construction is log and board. Knowing how to cut a log with a chainsaw into planks can significantly reduce construction costs as the cost of the finished plank is much higher. Let’s find out all the details of this process.
Tool selection
Not every chainsaw is suitable for this purpose. In order to cut logs with a chainsaw into planks, it is better to use a professional tool with a capacity of more than seven horsepower. An ordinary household chainsaw will not have enough power for such a job.
In addition, you should be aware that thicker logs will require more power, so it is better to choose specimens up to 35 centimeters in diameter.
Horizontal nozzle
This nozzle gives a higher accuracy. The device is a rigid frame that is fixed on the chainsaw tire from both sides. at the end of the tool and at its base. The device is suitable for small diameter logs not exceeding the length of the bar.
Longitudinal sawing of logs with a chainsaw with such a device should occur only after the log is well secured, since if it vibrates during operation, then it will not work to get a flat surface of the board.
Before proceeding with the dissolution of the log, it must be given a square shape by cutting off all unnecessary. It is clear that there will be much more waste in comparison with industrial production. When ripping a log with a chainsaw, the hardest part is to saw off the first board. To do this evenly, you can use a special frame that will serve as a guide and be the base for the stop. The quality of subsequent boards also depends on how smoothly you make the first cut, since the guide will rest on this surface in subsequent cuts.
Device for sawing logs with a chainsaw with your own hands
If desired, any such device can be made independently.
The first thing you need. these are goats for securing the log. Then the nozzle frame and guide.
Making goats for logs is not difficult. The main requirement is their height. Measure in advance a height that is comfortable for you so that you do not have to bend too low to the log or, conversely, work with your arms extended upward.
Making a frame-attachment will require more knowledge and skills.
First, you need to complete a drawing of the future frame, observing the scale. Then, from a square pipe with a cross section of 20 × 20 millimeters, weld the frame of the future fixture and weld the clamping elements onto it. Several holes must be made in the cross member for the bolt ties.
Oddly enough it sounds, but the most common difficulty in making a device for a do-it-yourself rip saw and other similar devices is the lack of welding. Therefore, before proceeding, calculate whether you have everything you need in stock.
Chainsaw benefits
Why is it better to saw logs with a chainsaw into planks than with a power tool? There are several reasons:
- You are not tied to electricity, but specifically to the outlet, and you can perform work in any place convenient for you.
- You can work in wet conditions.
- A good chainsaw is much more powerful than an electric one.
- You will be able to work with a chainsaw without interruption much longer than with a power tool, which constantly requires rest.
Regular cut
If you do not have any tools at hand, sawing logs with a chainsaw into boards is as follows:
- Sand the log, that is, remove the bark from it.
- Mark the log by tracing the required board dimensions.
- Saw the board along these lines.

Please note that with this method, you need to separately draw each next board, since quite a lot of wood is lost during sawing. up to one centimeter.
Cross-cut
Cross-cut is used to cut logs for firewood, as well as to create transverse wooden discs for building garden benches, decorating garden paths, etc.
Sawing a log across is done as follows:
- Place the log horizontally on wooden supports 0.5 m high.
- If necessary, you can clean it from the bark.
- Using an ax or a saw, make cuts-marks at equal distances from each other.
- Cut the log according to the marks.
No special attachments and chains are needed for this job. A regular chain will do.
Sawing logs into planks with a chainsaw
Sawing logs into planks with a chainsaw is the most convenient and fastest way. With the help of special attachments and devices, the independent production of practically flat boards is ensured, which are in no way inferior in quality to those that are manufactured industrially.
Nozzles for sawing logs
The chainsaw is a handy universal tool in the home garden. First of all, it should be taken into account that it has great power and compactness. Thanks to the centrifugal clutch, all systems and units of the mini-engine operate without overloads for a long time; power makes it possible to install any attachments. The chainsaw can be operated in any position and in any terrain, since it is autonomous, has a diaphragm carburetor.
How to adapt the mechanism for cutting logs into boards? To do this, just install the appropriate attachments on the chainsaw.
To cut a log along its entire length, the horizontal rip saw is suitable. Thanks to her, the boards are of the same thickness. After proper drying, they are suitable for construction. The nozzle is a small frame that is attached to the tire from both sides.
In addition, there is a lightweight nozzle that only locks on one side. As a result, the boards are not as smooth as in the first case. Fences, sheds are built from such boards.
The auxiliary tool is a drum debarker-stainer.
With its help, logs are easily cleared of bark.
The nozzle is a drum, it works thanks to the V-belt transmission. It is attached to the moving belts using special pulleys on both sides of the axis. By selecting the pulley diameter, you can select the optimal shaft rotation speed.
Sawing logs along
To get an even cut, you need to install a guide. It can be a mini-sawmill of an industrial design. But such devices are expensive and not everyone can afford. Therefore, usually the logs are fixed with homemade holders from boards with the same guide.
Sawing logs into planks is carried out with a chain for ripping. If not, a regular chain will do, which is sharpened at an angle of ten degrees. Only in the process of work will it be necessary to undermine it from time to time. A nozzle is installed on the chainsaw. a guide frame for an even cut.
To cut a log lengthwise, you must perform the following steps:
- Make a leading ruler. To do this, you need to fasten two straight long boards at an angle of 90 degrees.
- Place the log on the stops, thus fixing its position.
- Attach nozzle.
- Using self-tapping screws, attach the supports to the ends of the log on both sides. Check horizontality with level.
- Attach the leading ruler to the supports with self-tapping screws.
- Install another support board horizontally. which should rest on the ground and slightly raise the log.
- Using a chainsaw with a horizontal cutting attachment, saw off the first piece of log.
- Move the guide fence, fix it.
- Make the second cut of the log perpendicular to the first.
- Further, the leading ruler can be omitted. The resulting board will serve as a guide.
- Determine the thickness of the cut by the frame.
- Make the next cut perpendicular to the second. As a result, a piece of wood should remain, the underside of which is covered with bark.
- Make a fourth cut to separate the rest of the wood, which is with bark. You will get an almost perfectly flat block of wood.
- Then cut the bar to the middle.
- Turn it over to the opposite side and continue cutting to the end.
If the thickness of the boards does not matter, it is not necessary to cut off the barked edges. In this case, you can use a staining agent and cut into boards from the very beginning.
Observance of safety during work
To avoid malfunctions and accidents, you should observe safety measures when working with material and tools:
- Do not allow bystanders, especially children, into the work site when working.
- During work, you should use protective equipment against noise and sawdust, which scatter during cutting.
- You need to have a first aid kit with everything you need to use in case of cuts.
- When using a circular saw, a protective cover must be put on it.
- Do not pour gasoline into the heated tank of the chainsaw.
- Use the chainsaw only for its intended purpose, do not turn it on at full power if it is not in operation.
- No pressure on the saw when working.
- The cutting log should be placed on the right side.
The chainsaw is a handy tool that you can use to make your own planks. It is suitable for use in home gardens where you need to renovate or build new outbuildings. In such cases, a large number of boards are not required. Therefore, they can be easily cut from any logs in the required quantity. With the acquisition of skill, the work is done quickly, and the quality of the boards is excellent.

The advantage of sawing logs with a chainsaw
The method of cutting logs with a chainsaw has several advantages.
The ability to work under any conditions. the chainsaw is not afraid of moisture, therefore specialists can saw logs in the rain, the equipment in this case will not deteriorate.
High productivity. it is allowed to carry out work on wood throughout the day, but it must be borne in mind that the power of the device must be at least 7 horsepower.
Autonomous device. the equipment runs on gasoline, does not depend on electricity, the workplace is mounted on any site where it will be more convenient to carry out the process.
Convenience in work. the chainsaw is equipped with a smooth start and regulation of the chain rotation speed, these conditions ensure a high-quality result for beginners in this business.
The undoubted advantage is that the equipment is much cheaper than a small sawmill. During a breakdown, repair is inexpensive, does not take much time.
Rip saw attachment
It is used for sawing a log lengthwise, the process takes place in a horizontal position. After work, the master gets the same thickness for the product. The finished materials undergo a drying process, after which the boards are used in construction.
In appearance, the device is a small frame, it is attached to the tire on each side.
Cross-cut secrets
The cross saw is used to obtain firewood or decorative elements of the interior. Sawing is carried out according to the following principles:
- Place the log in a horizontal position on wooden supports, the height should be 0.5 m.
- Clean it from the bark.
- Using an ax or a saw, make small marks along the entire length, they should be located at the same distance from each other.
- Make a cut along the cuts.
Cross-cutting does not require the use of special tools or attachments. An ordinary chain is perfect for such work, but its rings must be strong.
Types of working attachments
Sawing logs with a chainsaw is carried out in different ways, craftsmen work with wood along the grain, as well as across it. It all depends on what attachments are used in the chainsaw.
Features of a homemade sawing option
Sawing a log into boards is easy with a do-it-yourself tool. Equipment manufacturing is simple:
- As a support, it is necessary to use a frame from a school desk or a pipe with a cross-section in the form of a square, its optimal size is 20 × 20, and more is allowed.
- Build two clamps, at one end mount a cross member with two holes for tie bolts, make a projection for the bus in the middle.
- For longitudinal sawing of logs into boards, it is important to make a support frame, its width must be 7–8 cm less than the length.
- Then two elements 10 cm long are welded to both sides, holes for bolts are made, a handle is attached in the middle for ease of use.
- After that, insert the clamps into the grooves, the bus is installed, everything is carefully fixed.
It is not difficult to work with a homemade tool, this will require two goats, they will serve as a support, and you also need to prepare a metal rail or board, the element will be a guiding element. A log is laid from below, the required height for work is adjusted.
Drum debarker. gummer
With the help of such a nozzle, it is easy to dissolve the log, it works due to the V-belt transmission. Attaches to belts on both sides using special pulleys. The speed of rotation of the shaft depends on the size of the pulleys, so the performance of the nozzle is easy to change.
This technology forces the master to carefully monitor each stage of the process; some specialists use an assistant during this cut. But this option requires increased security measures.
The technology of sawing logs into boards with a chainsaw
How to cut a log with your own hands
It is not necessary to purchase a device for sawing boards with a chainsaw. You can make it yourself. The simplest option is a device made of metal profiles. Such a nozzle will be not only convenient, but also stable, durable and reliable. Are you planning to make the most functional frame? Use mechanical gearboxes.
With them, the device will turn into a kind of machine for longitudinal cutting of logs. Mechanical gearboxes are needed to simplify the process of moving the chainsaw along the trunk. There is no need to apply force (to put pressure on the tool manually) to process the material. All you need to do is turn the gear knob. As for adjusting the thickness of the boards, it is convenient to adjust this indicator by using a nozzle made of metal profiles, raising the workpiece itself, and not displacing the gasoline saw in relation to it.
At home, you can also make a device that will cut a log not horizontally, but in a vertical plane. The only significant nuance is that it is more difficult to work with it compared to the previous frame (despite the fact that its design is simpler).
The difficulty lies in the fact that the operator has to apply force to move the tool along the workpiece. In addition to the chainsaw and the attachment, you will have to use a board and metal addition. This kind of support is attached to the log.
Important! Only experienced operators should make this kind of nozzle and support, since its operation is partly dangerous due to the fact that the board to be cut remains unsecured.
An alternative option is a carriage installation. To create such a frame structure, you need a pair of castors and a profile tube. This device differs from others in its mobility (ease of movement along the workpiece). In addition, the wheels will simultaneously serve as stops for the chainsaw, which means that additional devices will not be needed. In addition to these parts and the profile pipe, the only thing that is needed is an aluminum ladder (it will play the role of a guiding element).
It is necessary to select a ladder, taking into account its width, which should coincide with the distance between the wheels of the frame structure, which will be placed directly on its ends. The best option is attached to the log to be sawn using self-tapping screws, clamps or nails. The created device for cutting a board with a chainsaw with your own hands is placed horizontally.
It should lie as flat as possible. You can make sure that it is placed correctly using a building level. It is easy to align a ladder with a log, using boards (pieces) of different thicknesses. As for the tool itself with a nozzle, it is installed on a ladder, moving the saw along the workpiece, putting pressure on it with your hands.
We make goats for sawing firewood with a chainsaw ourselves
Wood processing, the purpose of which is to prepare firewood for the winter, cannot do without a well-known device. a goat, which not only facilitates this manipulation, but also allows you to do it yourself without attracting additional human resources. Every self-respecting homeowner faced with such moments is simply obliged to acquire such a “utility”, which does not mean buying it. Like other devices, you can do it yourself, but how. we will consider in order.
- We draw up a work plan with a detailed drawing so that this machine comes out geometrically correct. To simplify, we suggest that you familiarize yourself with the design, the leading parameters of which have already been calculated and marked in the photo below.
- We select durable consumables, including:
- wooden beams;
- posts made of strong wood;
- metal profile;
- metal pipes, rods, etc., which makes up the group of “home scrap metal”.
Each of the described methods, although it will lead to the final goal, still has one significant drawback. the lack of guarantees of personal safety, so you need to take care of this additionally.
Log sawing tools
Tools and cutting methods depend on the total volume of the logs, such indicators as length, thickness. In addition, you need to take into account the quality of the future lumber. Sawing a log involves working with different tools and specialized equipment. In order to get a small amount of lumber at home, a manual method of processing logs using a chainsaw or traditional hand-held hacksaws with teeth for longitudinal cutting is suitable.
The sawmill is perhaps the most famous type of sawmill equipment. This is a woodworking machine that has gang saws. On the sawmill, longitudinal sawn timber is obtained, for example, edged boards or beams. Sawmills allow processing logs with a diameter of 15 to 80 cm and a length of up to 7 m.
The most popular today are band sawmills. They are of two types: vertical and horizontal. The cutting tool in such equipment is a belt blade that is put on the pulleys. Working with band saws guarantees high quality longitudinal and mixed sawn timber such as planks and squared beams. This produces the least amount of waste.
In large industrial enterprises, mowing lines are used to cut wood. They allow a very high surface quality and precise geometry of the end products to be achieved. These mowing lines are characterized by the highest performance.
In addition to all of the above equipment, such types of highly specialized sawmill equipment are used, such as debarking, edging, band-dividing and other types of machines.
Types of equipment for sawing logs
Depending on the direction of sawing wood, the fixtures are divided into 2 types:
- Nozzles for longitudinal sawing of logs;
- Cross-section attachments.
Both types of fixtures include a whole list of different mechanisms, the use of which makes it possible to obtain the required amount of lumber and boards of suitable sizes, which can later be used for repair and construction purposes.
Design features of a homemade carriage
The carriage for a chainsaw is a straight and even guide along which the tool is fed onto the material being processed. To obtain a straight cut with the specified parameters, the saw is rigidly fixed on a movable platform, which, in fact, is called a carriage. The most common kit includes:
- guides. Their role is usually played by rails, channels, I-beams. A good solution to the problem is to use a duralumin ladder;
- carriage, which is a kind of trolley moving along the guides. It has a grip or support platform for fixing the chainsaw. There are designs in which only the frame is rigidly fixed, and the engine itself only rests on a special stand;
- device for adjusting the thickness of the lumber. Changes the lifting height of the saw blade, which allows you to quickly and accurately set the desired cutting thickness;
- trolley feed motor. This element is not required, since large amounts of work on such devices are not performed. In addition, mechanized feeding requires the installation of limit switches and other control equipment. However, many users prefer to install the mechanism to obtain an even cutting performance, which improves the quality of the boards.

There are also simpler carriage designs, which are a rigidly fixed chainsaw and a bounding frame. The material is fed onto a moving chain and the frame calibrates the thickness of the resulting board. This type of carriage is rarely used, since it is extremely difficult to feed heavy logs by hand, and the results obtained do not differ in an even and straight surface. The best option is to feed the tool onto a fixed log.
Important! Using this method does not require a lot of space. the length of the carriage guides should only slightly exceed the size of the workpiece.
Types of devices for sawing wood with a chainsaw
Anyone can assemble a homemade chainsaw lumbering equipment.
Depending on the principle and direction of the cut, structures for scaffolding are divided into:
- equipment for cross-cutting. used in the manufacture of small decorative wood products: items of room and garden furniture, wooden utensils, ornaments for the house and garden plot;
- structures for longitudinal cutting of wood. most often used by builders and repairmen. The main task of these devices is to obtain smooth boards of different lengths and thicknesses.
Both types of devices differ from each other in size and require chainsaws with different capabilities and characteristics to manufacture. The cross-cut design has a small size and saws with a capacity of 2 to 3.5 liters are suitable for its manufacture. from. Sawing logs into planks with a chainsaw requires a more powerful and durable gasoline tool. The saw must have a solid supply of traction and an effective cooling system, otherwise the risk of overheating and serious breakdown will increase. Such a structure most often has a fairly large size, so it is difficult to transport it between sites.
The technology of sawing logs into boards with a chainsaw
The method of cutting logs with a chainsaw has several advantages.
The ability to work under any conditions. the chainsaw is not afraid of moisture, therefore specialists can saw logs in the rain, the equipment in this case will not deteriorate.
High productivity. it is allowed to carry out work on wood throughout the day, but it must be borne in mind that the power of the device must be at least 7 horsepower.
Autonomous device. the equipment runs on gasoline, does not depend on electricity, the workplace is mounted on any site where it will be more convenient to carry out the process.
Convenience in work. the chainsaw is equipped with a smooth start and regulation of the chain rotation speed, these conditions ensure a high-quality result for beginners in this business.
The undoubted advantage is that the equipment is much cheaper than a small sawmill. During a breakdown, repair is inexpensive, does not take much time.
