So how can you cut a log into boards? And is it possible to cut logs into boards using a regular circular saw? Below we will try to answer these questions and describe in detail the process of sawing logs into boards using a regular circular saw.
For longitudinal sawing logs usually use a machine called a saw frame, in which cutting tool are strip saws tensioned in a frame that performs reciprocating movements. With such a machine, the log is cut into boards in one pass. In this case, the log is fixed on carts moving on rails. The log moves strictly progressively, without turning around its axis. The rails along which the cart moves act as guides, so they are positioned quite accurately.
Similar longitudinal sawing of logs into boards can be done using a circular saw, if the longitudinal movement of the log is ensured. It is clear that it is difficult to hold a round log in the desired position on a horizontal circular table. When sawing into boards, it will definitely roll and also “scour” left and right. This situation must be excluded. Let’s say right away that you can’t count on a circular saw as a guide. On the contrary, the saw should be completely freed from playing such a role. Therefore, to fix the log in the desired position, we came up with a fairly simple additional device - a fin. That’s what we called this device when we adapted a circular saw for sawing small aspen logs during the construction of a Russian bathhouse (Fig. 1). Together with a ruler (side guide) mounted on the table, the fin really helped us.
The thickness of the fin corresponds to the width of the cut, and the fin is installed with the ability to adjust its position. The two of them spread the log onto the boards. They begin to saw the log lengthwise, simply pressing it against the ruler, that is, in the same way as boards are usually sawed. After the fin is completely in the cut, a spacer with a thickness slightly greater than the width of the cut is inserted into the last cut (from the end of the log). A piece of flat file was used as a spacer. Next, a special clamp-handle was installed at the end of the log, which, firstly, held the board against the log until the end of the cut, and secondly, by which it was convenient to pull the log. The spacer file, which had a notch on both sides, kept the board “in place” well, that is, the board being cut did not move relative to the log due to vibration. The peculiarity of the design of the clamp was that it had an additional jumper, which, when installing the clamp in the center plane of the log, does not allow the clamp to rotate upward around the axis of the clamping screw when acting on it by hand. To ensure that the cuts when sawing a log are parallel, a flat is formed on the bottom of the log (first with an ax and then with a plane), which will determine the correct orientation of the cut at the beginning of sawing. The position of the ruler - its distance from the saw - determines the thickness of the board. So, having a ruler on the table, a flat on the log, as well as a “fin” and a clamp will ensure the success of sawing. During work, one of the “sawmills” pulls the logs using a clamp, the other presses the log against the ruler.
If you have to work alone, you will have to build some more. Firstly, in front of the machine (from where you are going to push the log), you should install a stand under the log (goats) with a height equal to the height of the machine table. Secondly, in front of the saw on the machine table, you will need a clamping device that can ensure contact of the log with the ruler from the beginning of sawing to the end. The clamping device must securely hold the log against the ruler, without creating much resistance to pulling the log during sawing. Such a device, assembled from a small wheel with a pneumatic tire, for example, from children's bike, and the rotary lever is shown in Fig. 2.
The easiest way to make a lever is from parts of an old bicycle frame. The seat and down tubes are sawed off from the bottom bracket assembly, leaving only the “chain” fork, from which, in turn, the rear fork is separated. The front fork, having previously removed the tips from the feathers, is welded to the “chain” fork. A handle from a bicycle handlebar is placed on the rod of the front fork. In the middle of the “chain” fork (opposite the front fork), plates with slots for installing the wheel axle are attached (welded) to its stays (see Fig. 2). In addition to this part, you will need to make a rotary nut - a support for the pressure screw, the screw itself, a traverse and the lever axis. You will also need some fasteners (nuts, washers, pins), shown in Fig. 2.
Before sawing the log into boards, flats are formed on it (bottom and sides). The side flats of the log ensure the strict direction of its forward movement when sawing and the constancy of the force of the pressure wheel, which makes the work calm and confident. Before starting sawing, the wheel is pressed against the log manually, while simultaneously turning the screw using the handwheel. The screw in this device serves only to fix the position of the lever with the wheel, therefore it is equipped with a small handwheel, for example, from a water tap. This makes it possible to dose the force of the wheel on the log “by touch”.
Now the market offers large assortment woodworking equipment. Many varieties of motor and electric saws have appeared. If you are going to cut logs into boards for a long time and seriously, and you don’t have a machine yet, consider using a saw from a chainsaw as a saw unit. Its drive will have to be located under the machine table, like a circular saw, and the saw itself will have to be installed vertically above the table. Using such a machine, you can cut logs into boards much more larger size and prepare lumber for doors, windows and other large products.

How to cut a log into boards with a chainsaw - a mini-sawmill at your home
Whatever you can do with a chainsaw - with the help of all kinds of attachments, this tool becomes very multifunctional. Don't know how to cut a log into boards with a chainsaw? Now we won’t talk about that!
- Chainsaw - a tool for all occasions
- DIY multi-tool
- How to cut a log into planks with a chainsaw - vertical attachment
- How to cut a log lengthwise - cut horizontally!
1 Chainsaw – a tool for all occasions
Most chainsaw owners have no idea what capabilities are hidden in this seemingly single-function tool. We are talking about what functions, besides sawing logs into firewood, a chainsaw can perform in in capable hands. But just think - the tool is absolutely autonomous, fill the tank with fuel, and work where it’s convenient for you!
A wide range of work is determined by 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 a chainsaw is its sealed fuel supply system, which, in combination with membrane type carburetor, allows it to work in a variety of positions, perhaps not upside down. In addition, the designers provided reliable protection components from overloads and breakdowns in the form of a centrifugal clutch.
Look at the chainsaw from a different point of view - you are holding in your hands a tool that is amazing in its capabilities! This is a universal drive for the most various kinds devices capable of not only cutting wood, but also cutting metal and stone, pumping water, drilling wells, and even serving as a low-power engine!
2 DIY multi-tool
The most popular attachment, which is even produced by chainsaw manufacturers themselves, is the petrol cutter attachment, which turns the chainsaw into an autonomous version of an angle grinder. The nozzle device is a bearing assembly with a shaft, with a pulley installed at one end, which is driven into rotation by a V-belt. At the other end there is a mandrel for fastening abrasive wheels. By changing circles, such a grinder chainsaw will be able to cut stone, tile, brick and even metal. Of course, the circle is hidden in a protective casing, without which work with such a tool would be clean water playing roulette - whether you're lucky or not!
Of course, there are a lot of people who will call this method crazy, because you can buy a normal grinder and not have to worry about changing any attachments! However, in practice, the idea is completely justified - high-speed saws equipped with such attachments work no worse than conventional grinders. Of course, they can’t compete with professional powerful tools, but in the household they justify themselves. This device has two undeniable advantages - autonomy and saving money.
Another professional attachment that can be bought in specialized stores is the so-called debarkers. Their functions exactly correspond to the purpose of the chainsaw and, in fact, increase its capabilities - in addition to cutting wood with the help of debarkers, it can be processed, namely, cleared of bark, growths and branches, and also cut grooves in logs, which is useful in the construction of wooden log houses, and give the rounded surface a flat shape.
Debarkers are divided into disk and drum. The first ones are used for cutting out recesses and mounting grooves, and drum ones are used to remove bark from logs; they are also called debarkers. The device is a drum or cutter mounted in bearing unit. The device is driven by a V-belt drive; for this purpose, there is a special pulley on the axis. Taking into account changes in the diameter of the pulley and the engine speed, you can also change the speed of operation of such a tool for optimal processing of wood.
With the help of a chainsaw and the appropriate attachment, you don't have to worry about emergency water supply at home if necessary - you can make a pump from this woodworking tool in a few minutes!
Essentially, the attachment is a regular centrifugal pump that is attached to the saw and driven by the same pulley and belt. The principle of operation is the same as for everyone else centrifugal pumps– one hose is lowered into the water, the second serves as a pressure hose.
How to make a grinder, pump, drill and sawmill from a chainsaw (review)
Before starting work, liquid is poured into the engine through the plug, which is necessary for the pump to “grab” the pumped water. When the turbine rotates, it creates a reduced pressure inside, due to which water is pumped out. The device is essentially the simplest, but imagine what use it can be when country house de-energized, and the water supply issue needs to be resolved urgently!
With the help of special attachments, a chainsaw can be turned into a drill or a winch, and even into outboard motor, capable of reaching speeds of up to 20 km/h with a fuel consumption of 1 l/h. However, these are already rarer cases, while devices for longitudinal sawing of logs, or, as they are called, mini-sawmills, are found quite often.
3 How to cut a log into boards with a chainsaw - vertical attachment
First of all, it should be noted that no one sets themselves the task of professionally cutting logs with minimum quantity waste. For professional work You also need the appropriate tool, but the attachment for longitudinal sawing of logs will allow you to solve many small problems on the farm. Let's imagine, for example, that an old pear tree has dried up in your garden, and you just need a few boards to fill a hole in the shed. Instead of using a tree trunk for firewood, you can use an attachment to get the material you need.
Devices for longitudinal sawing of logs are divided into vertical and horizontal. Most simple device This is precisely the first option: the adapter is attached to the tire at its base, and with the help of a guide bar the straightness of the adapter’s movement is ensured.
This entire structure is attached to a board, which serves as a stop for cutting and at the same time as a guide. The accuracy of such a device is not high - it can be used to cut rough boards or give a log a simple square shape However, such a device is assigned corresponding tasks.
4 How to cut a log lengthwise - we cut it horizontally!
Provides much greater cutting accuracy horizontal design, 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 cutting width. Of course, such a device is intended for small logs, the diameter of which will not be longer tires.
Using the guide element, you can set the required thickness of the boards. The most difficult thing will be to make the first horizontal cut - in order to get an even cut of the wood, you need to attach an additional guide frame to the log, which will serve as a base surface for the stop. At subsequent stages of dissolving the log into boards, the surface for support and guide is already flat surface previous cut.
This design is quite easy to work with. Before sawing a log lengthwise, it must be well secured along its entire length - the less it vibrates, the smoother the cut will be.. To avoid jamming of 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 quite a lot of waste compared to a conventional sawmill. To begin, give the log a square shape by cutting top layer from all sides, and only then proceed directly to dissolving the logs into boards.
It will not be difficult for craftsmen to make attachments of this kind with their own hands when working with welding and metal - the corresponding diagrams on the Internet are not uncommon, and from the material you will need several square hollow pipes, nuts and screws.

Sawing logs into boards using a chainsaw
Sawing logs into boards with a chainsaw: what is needed for this
Some people have the opportunity to take a certain area in the forest for logging in order to split the trunks, but how can you cut a log into planks with a chainsaw if you have never encountered this before? Those who have been logging for a long time can do this without any equipment - they just need to cut a longitudinal line on the trunk and use it to cut a beam or board.
But if you have never done this, then you will need certain devices, which we will now talk about and also show thematic ones in this article.
Cutting logs into boards with a chainsaw at a logging site
We spread the trunk onto the boards
Note. To cut a trunk into logs, you may need a sawmill or an electric or chainsaw with machine tools.
What will you need for this?
A chainsaw is the most affordable tool, and there is a whole series reasons:
- sawing of trunks can be done directly for logging. This does not require any fixed or autonomous sources power, only one tool;
- Compared to an electric saw, a gasoline saw has much more power. what is key point with longitudinal dissolution of logs;
- she has soft start and soft speed control. this means that the risk of breaking the chain during operation is reduced to almost zero (it is, of course, possible, but for this you need to try very hard);
- compared to a sawmill, the price of a gasoline-powered tool is several orders of magnitude lower;
- compared to electric unit, here the inertial braking works much faster;
- The operating instructions allow you to extend the time of intensive use up to 1 hour;
- it is possible to carry out work with high humidity air (rain, fog)
Device for dissolving trunks
As we have already said, experienced sawers can cut a log without any equipment, but for beginners they will definitely have to purchase or make their own machine for fixing the log, an attachment frame for the saw and a guide for an even cut.
It should not be forgotten that during such work the tool experiences very heavy loads. Therefore, if you want to do this professionally, then you will naturally need an appropriate model, that is, as powerful as possible.
Professionals call the most popular and best options: Stihl MS-660 or Stihl MS-880. Such units produce more than 7 horsepower, which ensures uninterrupted operation under heavy loads.
Frame parts
To adjust the thickness of the sawn board, a special steel frame is put on the bar, which is capable of adjusting the distance from itself to the bar.
The frame is ready - views from different angles
In order to make such a corner, you can buy a square tubular steel profile 20x20 mm, but you can also use the material at hand. For example, duralumin legs from an old school desk fit perfectly here.
A thick board was used as a guide.
As a guide, to make something like a stationary machine, you will need some kind of rigid metal, most likely steel, profile, or a thick, flat board under a log, as shown in the top photo.
In reality, it looks the same as in the picture - two sawhorses are installed and a guide (board or profile) is placed on them.
But it should be taken into account that such a device can only be used for short logs, since if it is increased (the distance depends on the thickness of the guide), there will be a deflection, which will lead to an unequal thickness of the material being produced.
Big Mill Timberjet
The thickness of the board or the cut will be even only if some kind of template is used to guide the chainsaw - a leading ruler or guide. It is very convenient to use the Swedish Big Mill Timberjit machine for this purpose, which you see above - it costs about 9-10 thousand rubles.
Here it’s up to you to decide whether you need such a device, but after spending once, you get a compact device that, together with the saw, can be delivered to the site on a motorcycle.
To get started, you will need a push-pull saw and a guide bar with two nuts. With this device you will be able to unravel logs up to 60 cm in diameter. Please note that in this situation you will have to acquire a chain for longitudinal cutting of the trunk, but if for some reason it is not possible to purchase it, then resharpen a regular chain at an angle of 10⁰.
The Big Mill Timberjet kit comes with a variety of parts that will help you install and secure the wooden guide. It turns out that when driving the chainsaw, the frame slides along this guide, and the tire does not move to the side.
Note. No matter what type of wood you process, in any case the chain becomes dull, and in order for your sawing process to occur without problems, it should be periodically sharpened.
The frame is installed on the guide
Sawing with a chainsaw - process
Now let's see how to cut a log into boards with a chainsaw:
- first we make a guide - take two even edged wooden boards and fasten them together in the form of a half-Tee;
- from pieces of the same boards we make stops for the half-Tee guide - fastening devices are included in the kit;
- roll up the log using a tilter and place it on a convenient base prepared in advance;
- secure the frame to the tire with nuts;
- after that we attach the supports. who hold a ruler to the ends of the log, checking its horizontal level;
- We fix all the fasteners with self-tapping screws. since it will be extremely difficult to remove the nails at the end of the work;
- we check that the cutting line does not run along the ruler, but 10 mm higher;
- start the saw and make the first cut;
- we free the log from the stops and rearrange the structure to the next cutting line so that it turns out perpendicular (90⁰) to the finished cut;
- Now we turn the log again and fix it with boards to the stop on the ground - you will no longer need the ruler, it will be replaced by the cut made earlier.
Conclusion
Of course, cutting logs into boards at home is not limited to just these two devices. If you do this yourself, then you will need to make a right angle on the trunk, and then using a frame you can prepare boards of any thickness.

Boards and timber are one of the main building materials. But not everyone has the financial means to purchase ready-made boards. In such situations, one of the solutions is to independently harvest wood on a plot taken from the forestry.
The advantage of a chainsaw as a tool for sawing logs
You can saw a log using a sawmill, gas or electric saw and additional accessories. When choosing one of these tools, you should consider the amount of work ahead. The cost of the cheapest stationary sawmill along with all components is 150 thousand rubles. A chainsaw is much cheaper. It is more convenient than an electric saw for the following reasons:
- Electricity is not required to operate the tool - this makes it possible to use a chainsaw on plots.
- It is more powerful compared to an electric saw.
- It starts smoothly and allows you to conveniently adjust the speed, which reduces the likelihood of a chain break.
- The inertial brake operates faster than that of an electric saw.
- Long working time without interruption – up to one hour.
- Can be used in conditions of high humidity.
Types of working attachments
When sawing logs with a chainsaw, various attachments are used.
- Attachment for longitudinal sawing. It is used for sawing logs lengthwise, the process takes place in a horizontal position. After work, the master receives the same thickness of the product.
Cutting logs with a chainsaw
The finished materials undergo a drying process, after which the boards are used in construction. By appearance the device is a small frame, it is attached to the tire on each side.
- Drum debarker (debarker). With the help of such an attachment it is easy to dissolve the log; it works due to a V-belt drive. Attached to belts on both sides, special pulleys are used for this. The speed of rotation of the shaft depends on the size of the pulleys, so the performance of the attachment is easy to change. This technology forces the master to carefully monitor each stage of the process; some specialists use an assistant during this cutting. But this option requires increased security measures.
- Sawing with a lightweight nozzle. The method is not very productive, but is used quite often. The element is fastened on one side, but the workpieces are slightly uneven. Such materials are necessary for the construction of sheds or fences.
Features of sawing using a homemade tool
You can easily saw a log into boards using a self-made tool. It's easy to make. To do this you need to do the following:
- As a support, you need 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 20x20, more is allowed.
- It is necessary to build two clamps, mount a cross member with two holes for coupling bolts at one end, and make a protrusion for the tire in the middle.
- To cut logs longitudinally into boards, you need to make a support frame; its width should be seven to eight centimeters less than the length.
- Then two parts ten centimeters long are welded to both sides, holes are made for the bolts, and a handle is attached in the middle for ease of operation.
- Then you need to insert the clamps into the grooves, install the tire, and secure everything carefully.
Work with homemade instrument It’s not difficult, for this you will need goats, they will serve as a support.
In addition, you need to prepare a metal strip or board to use as a guide. A log is placed underneath and the required height for work is set.
The procedure for performing preparatory work
To cut a log lengthwise, you need to perform the following sequence of actions:
- Take two straight boards and attach one to the other at right angles. The result is a strong guide line.
- To support the manufactured ruler, you need to make stops from boards.
- Moving the trunks must be done using a tilter.
- The log should be placed on a comfortable base.
- You need to secure the frame to the chainsaw bar using nuts.
- The supports of the leading ruler must be attached to the ends of the log, checking the horizontal position with a level.
- Self-tapping screws must be used to secure all brackets and structural elements. Nails are not suitable for these purposes, since they are difficult to remove in the future without causing damage to structural parts.
- The leading ruler needs to be attached to the supports using staples and its height adjusted taking into account that the cut will not go along it, but approximately one centimeter higher.
- The log needs to be rotated and the second board secured so that it rests on the ground and supports the log.
Procedure for performing basic work
- Now you need to start the chainsaw and make the first cut.
- Next, you need to free the log from the stops and boards and attach a guide ruler to the cut surface of the log in the direction of the next cut. The ruler is attached directly to the surface or to the ends of the log using supports. The second cut is made perpendicular to the first cut.
- The log needs to be turned and secured with a board against the ground.
- To perform further actions no guideline required. One of the cut sides serves as a guide.
- It is necessary to adjust the thickness of the cut on the frame and saw off the log from the other side so that you get a beam with bark remaining on only one side.
- This beam must be turned over and secured so that the attachment point of the fixing board is as low as possible.
- Then you need to adjust the frame to the required thickness of the board and saw the timber into boards.
Safety rules when performing work
- The circular saw should not be used without a protective guard.
- It is necessary to wear headphones, gloves, glasses, thick clothing and a respirator.
- You should not pour fuel into a hot tool tank; you need to wait until it cools down.
- Children should not be allowed to be present at the work site.
- It is necessary to start the tool on the ground with the chain brake engaged, which must be released only before starting to cut.
- You should always have a first aid kit on hand.
- When working, you need to hold the chainsaw by the arc handle, moving it forward along the guide. You should not put too much pressure on the chainsaw - it should move freely.
- Right-handed people should place the log on their right side, left-handed people should place it on their left.
Since ancient times, wood has been the most in demand building material. And if earlier rather primitive tools were used to process it, today the latest ones are used modern technology. So, for example, in order to cut wood and process it to required sizes, builders resort to the help of a sawmill. Unfortunately, such a tool is not cheap and therefore not available to everyone. Home craftsmen found a way out of this situation by making a sawmill from a chainsaw with their own hands. Tips for its design, drawings and video instructions can be found on numerous Internet sites, as well as in our article.
Types and features of chainsaw sawmills
Construction markets offer large selection sawmills, which are based on a chainsaw. Fixed in a trolley with rollers, the unit can be manually moved along a pre-laid rail track. A powerful chainsaw or band saw can be used to harvest wood.
For domestic purposes, large sawmills are most often not required, therefore optimal solution There will be a production of a functional homemade mini-machine. Such a unit will be small in size, and therefore can be easily moved if necessary.
More often the main element of such a device is a chainsaw, which can be purchased at a specialized store or use a Ural brand unit.
Do-it-yourself sawmill from a chainsaw: video instructions and drawings
Having the drawings available and having studied the video instructions, it is quite simple to independently make a structure for processing logs, boards and slats. Before starting work, you must select suitable place. You can install a sawmill using a chainsaw in an old barn, garage, hangar, or even just under a shed. If the room for the unit is closed, then you should take care of the hood.
Chainsaw sawmill - option No. 1
To make the structure, in addition to a chainsaw, you will need:
- two channels 8 meters long and 140-180 millimeters high;
- two rails;
- corners 50x100 mm and 40x40 mm;
- segments water pipe 25 cm as ties;
- steel plate 4-6 cm thick and 60 cm long;
- movable hoses;
- pipes with a diameter of 35-40 mm.
Making your own sawmill should start with assembling the base from rails and corners 50x100 mm turned upside down. They must be installed strictly parallel to the floor, so you need to use a building level.
- Along the length of the base, according to the drawing, holes are drilled in increments of 1-1.5 meters and with a diameter of 14-16 mm.
- Then, according to the number of holes, ties are taken and connected with bolts.
- Stands are made from metal squares and the base is placed on them. The distance between the outer posts and the base should be about 100 cm.
- To make the structure more rigid, braces between the posts can be welded.
After the base is completed and installed, you need to make a movable cart with your own hands. For this a corner is welded to the bottom of the steel plate 40x40 mm and the product is placed on rollers or bearings. Two corners are welded on top of the plate, to which a chainsaw is attached.
At the last stage of the work on making a homemade sawmill, it is necessary to make a structure for fixing the logs. To do this, movable hoses and pipes should be positioned at the required height and secured.
The first version of a homemade sawmill using a chainsaw is ready. There is another way to make a wood processing unit with your own hands. The tools and drawing for it will need the same, however, the design itself is more refined.
Do-it-yourself sawmill from a chainsaw - option No. 2
The structure consists of four main components:
- Driven saws.
- A mechanism for regulating the thickness of the board being produced.
- A mechanism for moving the saw part of the structure.
- Devices for fixing logs.
Since a chainsaw with a working engine and cutting teeth is already available, you will only need to make both mechanisms and a device for fixing logs with your own hands.
Mechanism for adjusting the thickness of the boards.
The logs are cut by raising or lowering the base, which must be welded to the plate using four nuts with bent edges. At the top of this device lock nuts must be installed which need to be tightened after the unit is set to required thickness processed material.
Mechanism for moving the saw.
The saw in the structure moves along the frame along guide angles, the distance between which should be 50 cm. To the racks it is necessary weld two rollers or bearings by 20 mm. The lower roller should keep the sawmill from lifting, and the upper one should rest on the guide angle.
Device for fixing logs.
On such a unit logs are secured using two ridges– stationary and moving by means of a screw. After the material to be processed has been installed, the moving comb is secured with screws in a stationary state. Now you can safely begin to operate a homemade sawmill made from a chainsaw.
A sawmill is an impressively sized The unit is quite dangerous to operate, therefore, before you begin assembling it, you should carefully consider the place where it will be used. It should be well lit, ventilated and have free space. The nearby warehouse for finished boards will greatly facilitate the process of processing the material.
For sawmill with electric motor You should very carefully install the necessary switches and circuit breakers, as well as do the wiring.
Since the most dangerous elements of the unit are all its cutting and moving parts, when assembling the structure they should be given special attention.
Before starting to operate the assembled equipment, it is necessary to check all fastenings and components, as well as the stability of the structure.
Operating instructions for a homemade chainsaw sawmill
After the structure has been assembled and tested, it must be tested in wood. To do this you need:
Jerky movements when cutting should not be made, as this can lead to the tire stopping.
It should be kept in mind that it is necessary to work within means personal protection , which include mittens, a robe, oversleeves and glasses. In addition, you should worry about protection for the moving frame in advance. It can be made from acrylic or transparent plastic. Such shields can protect against saw chain and shavings.
A sawmill assembled with your own hands from a chainsaw will allow you to produce high-quality sawn timber correct form. Therefore, if you often have to work with lumber, then such homemade equipment, made on the basis of the attached drawings and videos, will become an indispensable thing on the farm.

As we have already said, experienced sawers can cut a log without any equipment, but for beginners they will definitely have to purchase or make their own machine for fixing the log, an attachment frame for the saw and a guide for an even cut.
It should not be forgotten that during such work the tool experiences very heavy loads. Therefore, if you want to do this professionally, then you will naturally need an appropriate model, that is, as powerful as possible.
Professionals call the most popular and best options: Stihl MS-660 or Stihl MS-880. Such units produce more than 7 horsepower, which ensures uninterrupted operation under heavy loads.
Frame parts
To adjust the thickness of the sawn board, a special steel frame is put on the bar, which is capable of adjusting the distance from itself to the bar.
The frame is ready - views from different angles
In order to make such a corner, you can buy a square tubular steel profile 20x20 mm, but you can also use the material at hand. For example, duralumin legs from an old school desk fit perfectly here.
A thick board was used as a guide.
As a guide, to make something like a stationary machine, you will need some kind of rigid metal, most likely steel, profile, or a thick, flat board under a log, as shown in the top photo. In reality, it looks the same as in the picture - two sawhorses are installed and a guide (board or profile) is placed on them.
But it should be taken into account that such a device can only be used for short logs, since if it is increased (the distance depends on the thickness of the guide), there will be a deflection, which will lead to an unequal thickness of the material being produced.
Big Mill Timberjet
The thickness of the board or the cut will be even only if some kind of template is used to guide the chainsaw - a leading ruler or guide. It is very convenient to use the Swedish Big Mill Timberjit machine for this purpose, which you see above - it costs about 9-10 thousand rubles.
Here it’s up to you to decide whether you need such a device, but after spending once, you get a compact device that, together with the saw, can be delivered to the site on a motorcycle.
To get started, you will need a push-pull saw and a guide bar with two nuts. With this device you will be able to unravel logs up to 60 cm in diameter. Please note that in this situation you will have to acquire a chain for longitudinal cutting of the trunk, but if for some reason it is not possible to purchase it, then resharpen a regular chain at an angle of 10⁰.
The Big Mill Timberjet kit comes with a variety of parts that will help you install and secure the wooden guide. It turns out that when driving the chainsaw, the frame slides along this guide, and the tire does not move to the side.
Note. No matter what type of wood you process, in any case the chain becomes dull, and in order for your sawing process to occur without problems, it should be periodically sharpened.

Sawing with a chainsaw - process
Now let's see how to cut a log into boards with a chainsaw:
- first we make a guide - we take two even edged wooden boards and fasten them together in the form of a half-Tee;
- from pieces of the same boards we make stops for the half-Tee guide - fastening devices are included in the kit;
- roll up the log using a tilter and place it on a convenient base prepared in advance;
- secure the frame to the tire with nuts;
- after that we attach the supports. who hold a ruler to the ends of the log, checking its horizontal level;
- We fix all the fasteners with self-tapping screws. since it will be extremely difficult to remove the nails at the end of the work;
- we check that the cutting line does not run along the ruler, but 10 mm higher;
- start the saw and make the first cut;
- we free the log from the stops and rearrange the structure to the next cutting line so that it turns out perpendicular (90⁰) to the finished cut;
- Now we turn the log again and fix it with boards to the stop on the ground - you will no longer need the ruler, it will be replaced by the cut made earlier.
Conclusion
Of course, cutting logs into boards at home is not limited to just these two devices. If you do this yourself, then you will need to make a right angle on the trunk, and then using a frame you can prepare boards of any thickness.

Centuries and millennia pass, new materials and technologies appear, but wood, stone and metal have been and remain the main materials used by humanity for its needs. Products made from them surround us everywhere, wherever we are, wherever we go.
Particularly noteworthy is the wood, which creates an atmosphere of coziness and comfort everywhere. Metal and stone are colder and more 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 interior decoration, however, after being brought into the appropriate form.
Before you cut a log correctly, you need to inspect it. If on outside There are no significant flaws in the tree, then processing can be done quickly and with virtually no loss of wood.
Logs must be sawed in such a way that the resulting materials have equal density. And to do this, you need to remember that the wood on the north side of the trunk has a higher density than on the south. Cutting a log lengthwise begins with removing the slab; this part is removed from both sides of the tree to create a beam that will not roll.
We place the resulting timber on one cut side, and the other looks up, and the cutting will begin from there. Now you can cut the remaining log into appropriate lumber or boards of equal thickness. The result is a set of unedged boards, in which the raw edge (sometimes even with tree bark) must then be cut with a handsaw. Now we can consider the work completed.
How to saw a log lengthwise - disappointing realities
All these recommendations are good for ideal logs, but, as you know, ideal is quite rare. Basically, almost all logs have various shortcomings, and you have to adapt and invent cutting methods in order to avoid wood loss and get as much wood as possible. quality material.
As in the previous case, Before sawing a log lengthwise, you need to remove the slab from it. For those who don’t know, a slab is a board that has one sawn surface, and the other either is partially processed or is not touched at all.
After removing the slab, the next step is to make an unedged board, this has already been written about above. Longitudinal cutting of a log produces boards, but with raw edges. In the process, because the log is not perfect, it is necessary to periodically turn it over and identify it best options further use. Sometimes, while cutting one log, you have to turn it 180 degrees several times to minimize defective boards.
If it is possible to obtain good quality material from the other side of the log, you need to continue the process from there and so on until the wood is completely used.
Very often, after cutting, timber remains; it can also be used 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 lengthwise with a chainsaw? To perform this operation, experts recommend that you first secure the log and only then carry out processing. In addition, in order for the cut to be as smooth as possible, it is necessary good sharpening chain of this saw so that it does not get pulled to the side, or buy a special chain designed for longitudinal cutting.
In addition, it is advisable that the logs are not long, because It is very difficult to make something high-quality by hand from a long workpiece. Also in construction stores Special attachments for logs and saws are sold, which are called mini-sawmills; they allow you to do work at home quickly and efficiently. The only drawback of such equipment is its high cost.
Act upon use hand saw 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 raw side 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 is constantly tending to wobble, and it is also simply physically difficult to hold it in your hands all the time.
All experts agree that if possible, it is better to take the material to a sawmill, where they will be processed using professional equipment. least losses and extremely smooth edges.

Some people have the opportunity to take a certain area in the forest for logging in order to split the trunks, but how can you cut a log into planks with a chainsaw if you have never encountered this before? Those who have been logging for a long time can do this without any equipment - they just need to cut a longitudinal line on the trunk and use it to cut a beam or board.
But if you have never done this, then you will need certain devices, which we will now talk about and also show a thematic video in this article.
We spread the trunk onto the boards
Note. To cut a trunk into logs, you may need a sawmill or an electric or chainsaw with machine tools.
What will you need for this?
A chainsaw is the most affordable tool, and there are a number of reasons:
- sawing of trunks can be done directly for logging. This does not require any stationary or autonomous power sources, only one tool;
- Compared to an electric saw, a gasoline saw has much more power, which is a key point in the longitudinal dissolution of logs;
- it has a soft start and soft speed control, which means that the risk of breaking the chain during operation is reduced to almost zero (it is, of course, possible, but for this you need to try very hard);
- Compared to a sawmill, the price of a gasoline-powered tool is several orders of magnitude lower;
- Compared to an electric unit, inertial braking works much faster here;
- time of intensive use, the instruction manual allows you to extend it up to 1 hour;
- It is possible to carry out work at high air humidity(rain, fog)
As we have already said, experienced sawers can cut a log without any equipment, but for beginners they will definitely have to purchase or make their own machine for fixing the log, an attachment frame for the saw and a guide for an even cut.
It should not be forgotten that during such work the tool experiences very heavy loads. Therefore, if you want to do this professionally, then you will naturally need an appropriate model, that is, as powerful as possible.
