DIY band sawmill, a simple and reliable machine. The principle of making a band or disk sawmill with your own hands

The band sawmill provides sawing of wood for its subsequent use for the purposes of repair, construction, production of various wooden products. An assembled band sawmill with your own hands allows you to replace factory machines, the line of which is presented in a wide price range.

Every experienced framer band sawmill must know how it works this device, what spare parts are used, how to change these spare parts, etc. Without this, work even on a mini machine is unacceptable. The instructions must be strictly followed, whether it is a mini or an industrial unit.

The sawmill structure consists of two rotating components. These are pulleys. Moreover, car wheels are often installed instead of pulleys. The advantage of wheels is that they are easily accessible; some people, when assembling their own sawmill with their own hands, do not have to spend money on buying wheels. Specialized pulleys will cost more;
The saw is pulled between the pulleys or wheels of the sawmill;
The reels of the sawmill rotate, due to which the pulleys perform reciprocating movements for the saw. This ensures cutting of the workpiece;
The factory and homemade band sawmill operates in a horizontal plane;
The cutting part of the sawmill is fixed on a trolley, which is movable;
The mobile cart moves along special rails of the sawmill. This distance is equal to the length of the tree being processed;
Fastening the log to the frame band press carried out in a stationary state. To ensure the wood is fixed correctly, it is necessary to provide clamps in the design. They secure the log, allowing the machine to cut it;
The length of processing directly depends on the length of the sawmill rails intended for moving the trolley;
The maximum width is formed due to the distance available between the tension components of the cutting tool of the band machine.

A skilled framer for a band sawmill is able to make a full-fledged machine with his own hands, which can be used to effectively saw wood elements or entire logs. It all depends on what type of wood you need to work with. Some drawings allow you to make a mini machine for working at home. Or you can make larger models. Typically, such designs are chosen by experienced sawmills who need to process large quantities of wood. Based on the drawings, you should additionally consult with specialists and watch video tutorials on assembling a large or mini machine.

The instructions for working on a sawmill are not complicated, although a framer on a band sawmill must know literally everything about the tool he is working with. How to change spare parts, how to properly adjust the carriage, how to work on different types of wood.

Conditions for quality cutting

In order for the band saw to operate correctly, sawmills point out the need to meet several conditions:

The log must be securely fixed to the band sawmill. The instructions clearly state this, otherwise it will not be possible to saw the workpiece correctly and safely;
Gradation has been completed, for which an electronic ruler is suitable, all cutting parameters have been set;
Check the tension of the band saw, make sure that sharpening is not required;
Make sure that the cutting tool matches the characteristics of the material being processed.

Sharpening should be done periodically, as the instructions say. Correct sharpening ensures preservation of the cutting properties of the band saw, and also guarantees effective processing of logs and wood.

An electronic ruler is a purely individual choice. Experienced sawmillers claim that they do not need an electronic ruler due to their experience. Although, if a framer has high hopes for a band sawmill as a tool capable of making the most accurate cut of a log, it is better to have an electronic ruler installed.

Sawing and its stages

If you don't know how a band sawmill works, the video will help you get a clear idea. The work takes place in three stages.

It is necessary to sort the wood, disassembling it according to length, diameter, etc. The framer on the band sawmill manually adjusts the dimensions of the wood to the capabilities of the device.
Sawing is being carried out. But before the very first cut, sawmills are required to check whether sharpening has been completed, whether the electronic ruler is working, whether all settings are set. Only after this can you cut the log and make the required cuts on your industrial or mini machine.
The logs are finished by hand. If the Cedar band sawmill can provide enough exact result processing then work homemade devices has certain deviations. Therefore, at home, it is often necessary to modify products with your own hands, using a plane, grinder and other tools.

DIY assembly

If you need high-quality, high-performance sawing of logs and wood, you should pay attention to factory models of machines. The MV 2000 band sawmill is in noticeable demand, although the Baikal band sawmill is not much inferior to it.

If you want to make a device with your own hands, no one will prohibit it. But you need to familiarize yourself with the basic principles of assembly.

Start with drawings. You can make the drawings yourself, or find ready-made options. They should indicate all dimensions, length, width, parameters of the future machine, its technical specifications. This way you will know what materials you will need for assembly and how much money it will cost.

Among the main components of the future design, the following should be highlighted:

Ramu;
Guides for moving the saw element;
Screw assembly for moving the cutting belt;
Spring for tensioning the saw;
Pulleys - fixed and movable;
Protective case;
Transfer units;
Electric motor (can be replaced with gasoline);
Container with liquid for the cooling system;
Stopper;
Devices for fixing workpieces.

Pay attention to the cutting element. Many sawmills use electric and gasoline saws when creating homemade mini machines. They are great when you need to do a small amount of work.

The use of wheels can replace pulleys. The main thing is to correctly select the size of the wheels so that they firmly and effectively hold and tension the saw element.

First, the rails are assembled. Approximate length - 8 meters. To avoid deforming them under the weight of the log, strengthen the structure metal legs. If you plan to work with large workpieces, it would be correct to install the machine permanently and make a foundation for it.
A seamless steel plate will act as a movable cart. Its length is 60 centimeters and its width is 80 mm greater than the width of the rail track.
A movable carriage, also known as a trolley, is also designed for mounting wheels or pulleys. One of the wheels is fixed in a stationary state, and the second will be movable.
It is not recommended to place the pulleys parallel to each other. It is better to make a deviation of 4 degrees in the vertical plane. This will prevent the tape from flying out of place while the device is operating. Not every instruction indicates this, although the recommendation is important.
If possible, make a control unit for the sawmill. But on simple models a steering wheel is used, the movement from which can be transmitted through a metal target.
The assembly is completed by installing clamps on the sawmill.
Leave the installation of the cutting saw and electric motor for last.

As you upgrade your homemade tape device, it may receive an electronic ruler, a more powerful engine, and all sorts of spare parts. Also, some expand the dimensions of the machine, which ensures work with larger workpieces on the sawmill.

If you don’t want to assemble a band sawmill yourself, the instructions seem complicated, then choose factory models. The Baikal band sawmill, which is in impressive demand, costs about 150-200 thousand rubles. The price is not small, but the capabilities of the machine are enormous.

A favorite material in construction, in the manufacture of utensils for the home and household, as well as a wide variety of decorative items, furniture, etc., just like hundreds of years ago, wood remains. And the owner, who has the skills to work with equipment and skilled hands, can make a sawmill with his own hands. This will make it possible to prepare boards and other lumber on site according to your own needs, the right size and type, and it will cost much less than buying finished products.

This is especially true when it is necessary to process a large number of boards and other lumber. Although it is generally accepted that the best option It will be possible to purchase a ready-made device, but making it yourself is also possible and affordable if you have the desire and minimal working skills. Based on this, it is worth understanding the question of how to make a sawmill on your own so that it is reliable, convenient, safe and meets the requirements in this particular case.

The easiest way to have a beautiful front lawn
You've certainly seen the perfect lawn in a movie, on an alley, or perhaps on your neighbor's lawn. Those who have ever tried to grow a green area on their site will no doubt say that it is a huge amount of work. The lawn requires careful planting, care, fertilization, and watering. However, only inexperienced gardeners think this way; professionals have long known about the innovative product - liquid lawn AquaGrazz.

When setting yourself the task of making a sawmill with your own hands, you should first of all decide on the volume of work for which this unit is planned to be used, as well as the type and geometry of wood (raw materials). Based on these parameters, you can already choose the type of sawmill that is best suited for solving the tasks.

When designing and manufacturing a mini-sawmill, maximum attention should be paid to safety - any equipment of this class is equipment increased risk and requires a very attentive attitude.

The presence of a sawmill is invaluable in the household of a craftsman who often works with wood, because it will help solve such non-trivial problems self made questions like:

produce a significant number of products of the same size and shape;
sawing logs according to a predetermined pattern.

In industrial sawmills, logs are processed according to two standard schemes:

Sawing a stationary log with a cutting element mounted on a mobile trolley;
The log is pushed (or pulled) along rollers or rollers through a stationary cutting block.

When making your own sawmill, both of these schemes are used, and its specific type is selected depending on the structure planned for assembly.

If we talk about the types of sawmills, the main ones are corner, strip, and chain. Additionally, when we're talking about Regarding homemade units, it is worth highlighting devices using a chainsaw as a basis. Each of the listed types has a number of features and design differences from others, and therefore requires separate consideration.

Important! To produce a high-quality, reliable, safe and efficient unit on our own It is imperative not only to carefully select the type, design, material and parts, but also to work out and prepare drawings that must be strictly followed.

Band sawmill

The general principle of operation of a band sawmill is that a trolley with a band saw blade moves along a log rigidly fixed on a stationary platform, cutting it. The location of the sawing part of the tape is horizontal, and the tape itself is well tensioned. By adjusting the height of the band saw, the size (thickness) of the sawn part of the log (board, timber, etc.) is calibrated. Such a device can usually work with logs weighing up to 300 kg.

Assembling a sawmill of this type on your own is quite difficult, since achieving coherence in the work of all structural elements is a difficult task to achieve. In addition, to install the structure, it is necessary to select special components, tools and devices, and draw up fairly complex drawings, taking into account all structural elements.

Assembly of the complex must begin by preparing a level area suitable size and sealing its surface (if it does not have a hard coating). The next stage of work will be the assembly of the frame of the unit, which should begin with the manufacture and installation of rails for the trolley. You can use a corner with the shelf facing up as a rail.

Sleepers from a pipe, channel or angle are welded between two rails to securely fasten them to each other. A movable log fastener is attached to the sleepers, which should securely secure wood of any diameter (within the limits planned for processing).

Now it is necessary, according to the prepared drawing, to assemble and install the mobile cart on the rails and check its progress along the entire length working area. The circuit will also require wheels (you can use assembled automobile wheels, along with tubes and tires), which are used to tension the band saw. Their installation on the frame is the next stage of installation.

All that remains is to mount the electric motor, connect it via a pulley to the mechanism of the unit and check the operation by starting it.

After checking the operation of the mechanisms and parts, you can install the tension band of the saw, make adjustments and test run the sawmill.

Chain type installation

The operating principle of a do-it-yourself bus sawmill is very similar to a band saw, but it uses a chain saw rather than a band saw as the cutting element.

However, it should be noted that its design is much simpler, the installation itself is smaller in size, and a smaller number of parts that require significant adjustment are used - this together makes the bus mini-sawmill easier to independently manufacture and use than a band sawmill.

The beginning of the manufacturing process also begins with the preparation of the working site on which it is installed metal frame future sawmill in such a way as to provide free access to it from any side. A frame is assembled from profiled metal, in which technological holes are drilled (the number will depend on the required step). Now you need to mount the frame with stiffeners. As a result, the base of the machine is assembled.

A movable cart is assembled on the frame by installing stops, gaskets, clamps and an electric motor. After checking the functionality of all parts and structural elements, you can install and tension the saw chain and make a test cut, make adjustments and get to work.

Mini sawmill corner disc

A do-it-yourself angular circular sawing unit will be very useful in a home workshop for processing wood into different type lumber. Perhaps this is the most versatile and powerful mini sawmill - you can make more complex design it won't work.

Important! The design of the corner circular sawmill is most optimal specifically for self-production - units of this class have a very high price and are not readily available. In addition, it is multifunctional and can process very large volumes of raw materials.

After preparing the drawings and purchasing all the necessary components and structural elements, you need to prepare, as in previous cases, the installation site. A frame base is assembled on it, the material for which is metal pipes and high-strength guides (the design involves heavy loads and the material must correspond to them).

Guides for a mobile platform should ideally be made from rails, again due to increased loads. The next stage of assembling the carriage should be characterized by increased attention to maximum compliance with the dimensions according to the drawing.

It is recommended to use a high-power internal combustion engine (ICE) as a drive - this will increase the efficiency of sawing large quantities of raw materials and simplify working with dense types of wood. It is best to use a chain transmission for torque transmission, although if the design is not well thought out, this can lead to increased heating of the transmission mechanism. For safety reasons, all moving parts of the drive must be enclosed or protected by a casing.

Chainsaw as a basis for a sawmill

Most craftsmen who work a lot with wood have a chainsaw. Due to its availability, low cost and simplicity, it is quite easy to make a sawmill from a chainsaw with your own hands. There are quite a lot of options for mini-sawmills, the main element of which is a gasoline saw, but they are all distinguished by their simplicity, small size, and mobility (it can be easily moved from place to place).

Important! In the overwhelming majority of cases, individual craftsmen do not need heavy-duty installations and huge volumes of raw material processing. Therefore, from the point of view of ease of assembly, cost, and ease of maintenance, a do-it-yourself sawmill made from a chainsaw is the optimal solution for your own household.

To make a sawmill from a chainsaw, you will need the following components:

channel;
metal corners;
rails;
chainsaw as the main element.

At a place prepared for work, which needs to be leveled if necessary, a frame is assembled with holes for fasteners and ties made of metal pipes. Fastening is done using bolts. It is necessary to constantly monitor the angular dimensions to ensure that exact perpendiculars (right angles) are maintained. Additional stiffening ribs should be provided in the design, which will strengthen the structure.

The basis for the mobile platform is a metal plate with two corners welded on the bottom side. This base is mounted on rollers ( better bearings). On the top of the plate there should be corners welded to which the chainsaw will be attached.
The last stage is the installation of the structure to securely fasten the log when cutting it.

A do-it-yourself band sawmill allows you to save significantly if there is a need for constant wood processing during the construction of houses, on the farm, or if you have your own small production.

Of course, you don’t have to rack your brains and buy a tool, but making it yourself, as mentioned above, will cost much less.

The band sawmill is better known to many as a band saw. Depending on the scope of work, the type of tool is selected.

The sawmill can be belt type, chain or disk type. We are considering tape type manufacturing.

The principle of operation of a band sawmill is very easy to explain using the example of spools of thread.

The whole design resembles the rotation of two spools, between which a thread is stretched. This thread plays the role of a saw, and the distance between the coils is maximum size logs

What a band sawmill allows you to do:

Prepare logs, that is, adjust them to the same size and shape;
Sawing logs according to a given pattern after setting up the equipment;
After sawing, small defects remain that cannot be eliminated using homemade sawmills, therefore further processing wood is done by hand.

The band sawmill works as follows: the log is fixed on the platform and remains motionless, the mobile cart begins its movement and cuts the tree, the saw is in a horizontal position.

In order to ultimately get a board of the desired size, it is necessary to initially set the parameters by the operator. The saw acts as a saw blade, which must be well tensioned.

How a homemade sawmill works, see the video.

Before work, you need to prepare the equipment: to do this, sharpen the saw and spread the teeth.

What materials are needed to create a sawmill?

It should be noted that materials are selected depending on whether the drawings are made or not, because it is correct drawing is the basis of a quality product, thanks to which the calculation of materials is made:

Pulleys can be taken new or old in good condition;
Pipes of different diameters;
Rails - you can make it yourself from corners. It is better to place the corners edge up, this is necessary in order to extend the “life” of the wheels;
Profile pipes for creating sleepers;
Channel.

In addition to materials, you will need the following tools:

welding machine;
milling machine;
Bulgarian;
drill, it is more convenient to use an electric one;
hammer;
pliers;
sets of screwdrivers and wrenches;
clamp;
bolts, nuts and other fasteners;
rulers, tape measure, squares, etc.;
hacksaw.

Sawmill design

The organization of work is based on the block principle.

It involves various variations of the device, starting from the basic one, where the saw is fed manually, to the most complex units, when the saw is fed automatically, the cutting thickness is set, the electronic system is programmed, etc.

Components of the structure:

to organize the movement of the saw blade, a frame with two guides is used;
screw mechanism for lifting the belt;
hydraulic or spring unit for tensioning the tape;
driving and driven wheels (pulleys);
wheel guard casing;
tape holder;
V-belt transmission;
electric motor;
rail for carrying out the movement of the band saw;
eccentric clamps for holding the block (log);
emphasis;
tank with liquid for wetting.

To create a smooth, reliable product, it is necessary to make drawings according to which the entire structure will be assembled.

At the same time, the drawing must be studied and understood, otherwise you can simply lose not only time, but also money.

First, the bed (fixed part) of the machine is made, which has a U-shape.

It can be made from two channels, which can be replaced with two rails (in the absence of the first materials). If you use rails, they need to be installed so that the sole is on top.

The bed can also be made from corners (50x100 mm).

The height of the channel should be at least 14 cm, the length should be about 8 meters.

Holes need to be drilled along the entire length of the materials in increments of 1-1.5 m. After this, using pipes whose length is 25 cm, the channels need to be pulled together.

Threaded rods or bolts are used.

In this case, the structure is additionally strengthened with the help of braces, since it is necessary to achieve rigidity of the product. See drawing.
Next, a mobile cart is assembled, the dimensions of which are set depending on the width of the frame, while the cart on both sides should be slightly larger (about 8 cm) than the frame.

The length of the mobile structure should be approximately 60 cm. Most often, the trolley is made of steel plate, the thickness of which is 46 mm.

A special steering wheel is installed on the side of the structure to provide control of the trolley.

The guides on the sides must be equipped with sprockets to which the control wheel is connected.

The entire structure moves using a tensioned chain, which prevents free movement of the steering wheel.

To prevent the log from jumping out during operation of the sawmill, it is necessary to make clamps that are made from pipes.

It is more convenient to use pipes internal diameter which does not exceed 35-40 mm, since movable rods will be installed inside.

Clamps must be placed on top of the pipes. Metal corner is the material from which clamps are constructed. Clamping cam mechanisms can also be installed.

If the clamping elements are less than 15 mm, then there can be no talk about the reliability of the design.

If you work on the engine at the end of the work, you must purchase it in advance so that the proportions of the entire structure are correct.

For the example under consideration (bed length is 8 m), the engine power must be at least 10 kW, and the saw diameter must not be less than 1 m.

Otherwise, the dimensions of the entire structure must be revised to smaller ones.

To make a homemade sawmill work more efficiently, you should pay attention to some recommendations:

The structure must be stable and strong, since you have to work with logs of different weights and sizes;
Equipment assembly work must be carried out directly at the site where it is planned to be located. This is due to the massiveness and heavy weight of the structure;
It is necessary to constantly monitor the operation of the equipment and adjust the settings, since the design is done by hand, without the use of precise programs and computerization;
Homemade sawmills are “scattered” with shavings, so you need to either build additional structures or clean up after the work is completed;
A wide band cut affects the generation of a large amount of waste;
To ensure efficient work for a mobile trolley, it is necessary to use gaskets and plates, and the gaskets must be 0.5 mm thicker than the channel;
The electric motor can be easily replaced with a gasoline engine. This option will be simpler, because you can use a chainsaw, or rather its engine. The chainsaw blade will serve as a tape. How to make a gasoline band sawmill, see the video;
All fastening elements must be securely fixed to ensure safe operation of the entire structure;
To ensure efficient operation, the saw must be sharpened and the teeth set apart.

Disc sawmill

Let's look at a simpler type of homemade sawmill.

In order to make a circular sawmill, you will need to find circular saw. An electric motor will be used as a motor.

First you need to make a welded frame, on which you will need to place a metal plate with a slot for the disk. From below to the plate you need to attach the plate shaft on bearings and pulleys.

The electric motor wheel is connected to the saw by a belt.

To ensure good belt tension, it is necessary to use the weight of the engine itself, and you can also use weights. The circular sawmill is ready.

During the initial processing of wood, you will need a sawmill. This equipment can be of several types - disk or tape. For self-production, preference is given to the first type, since it has good performance properties and a relatively simple design.

Operating principle of a circular sawmill

Before making the design, you should familiarize yourself with the operating principle and purpose of the mini circular sawmill. In most cases, it is necessary for sawing logs of large and medium diameter. As a result, boards or timber are formed.

The main component of the design is the power plant. It should provide the proper number of revolutions of one or two disks. In addition, for maximum automation of work the following components are required:

supply line. It can be stationary or with a system for transporting logs to disks. Most often they prefer to make the first option, since it is the least expensive when made independently;
cutting unit. Consists of one or more saws. Depending on their location, it can be horizontal or transverse. For simultaneous processing of logs in two planes, a miter sawing machine is required;
control unit. Most often it is located on the outer part of the cutting unit. With its help, the operator can adjust the engine speed, turn the equipment on or off.

A corner sawmill is necessary for tangential and radial cutting of workpieces. Thanks to its design, the entire volume of the log is used as efficiently as possible.

Mini double-disc models usually come with two motors. However, their power and number of revolutions may not always match. These parameters must be calculated in advance and the corresponding cutting unit must be made.

Choosing a circular sawmill design

The simplest homemade sawing structure consists of a table with a cutting disc above the surface. You can make a similar model at home. However, its productivity will be low.

The main disadvantage of this design is the need to independently supply the log to the sawing site. This will lead to disruption of the geometry of the future board or timber. Therefore, these types of equipment are only used for processing small workpieces or sheet material.

The corner sawmill has much greater functionality. It performs two cuts simultaneously in horizontal and vertical position. However, its production is more complicated than that of the model described above. The DIY circular sawmill has the following design features:

movable cutting carriage. It moves along guides located on the body of the stationary platform. The carriage contains two motors, on the shafts of which saw blades are mounted. It is imperative to make a device to adjust the position of the disk edges;
stationary platform for workpieces. It is equipped with log clamps. Otherwise, displacement may occur during operation, which will lead to deformation of the product.

A similar mini design can be made from scrap materials. It is important that it can withstand the loads and constant vibration that will inevitably appear during operation.

If the sawmill is designed only for the production of boards, you can install another vertical one instead of a horizontal saw. This will increase the productivity of the equipment.

If the sawmill is needed for commercial purposes for processing large volumes wood - fit in self-production should be done very carefully. Homemade models will not always be able to provide high-quality cuts under constant load. But for small jobs, you can make the structure yourself.

First of all, you need to choose the right power and speed power unit. When installing electric motors, such problems will not arise, but you will have to connect a 380 V line, since installation of three-phase models will be required to ensure performance. If you plan to use internal combustion engines, which happens extremely rarely, install an overdrive gearbox to increase the speed of the saw blades.

First you need to make mini drawings of the future design. Since scrap materials will be used for manufacturing, their exact dimensions should be taken before creating the diagram. There are no exact rules for the manufacture of a double-disc sawmill - the design in each case is purely individual.

However, to create reliable equipment, it is recommended to follow the advice of professionals:

the frame must be made from channels No. 4 or No. 6. For connection, two methods should be used - mechanical with bolts and welded. This will ensure maximum strength and, as a result, durability;
It is best to use standard P50 rails as carriage guides. They must not be deformed or bent. The wheels for the platform are matched to them;
During manufacturing, it must be taken into account that the width of the carriage and the mobile platform must be the same. Minor adjustments are allowed using the wheel hubs;
engine location. Since most models are air cooled - power plant should be located as far as possible from the cutting site. To drive a disk, you should make a shaft or chain transmission;
To protect the operator, a steel shield is installed on the platform. It will prevent the appearance dangerous situations. But at the same time it should not interfere with normal visibility.

During operation, it is necessary to periodically check the condition of the equipment. A homemade installation may lose its original qualities during long-term use. Also, do not forget to sharpen the saws on both sides, and after their service life expires, replace them with new ones.

To make a manual sawmill with your own hands, we will need (depending on the design):

construction trestles;
boards;
channels;
corners;
electric motors;
set of hand tools;
the presence of two pairs of rails;
metal plates.

In the video you can see an example of a homemade corner circular sawmill:

When it is necessary to process a large number of boards and wood, it is best to use a self-made sawmill. Many people believe that it is best to purchase a ready-made unit, but making it yourself will not be difficult. The main thing is to decide what the volume of work ahead will be, as well as the wood, after which you need to choose the type of sawmill to successfully complete the task.

Assembling the unit with your own hands, special attention should pay attention to safety issues, because such a device is considered a high-risk item. Manufacturing various types sawmills are presented further in the video.

The principle of operation of the sawmill

Explain, how does a sawmill work, using the example of spools of thread. This device resembles the rotation of two spools with a thread stretched between them. It is this that acts as a saw, and the distance between the coils will be optimal size logs

A DIY sawmill allows you to:

adjust logs to one shape and size;
saw logs according to a specific pattern after the equipment is set up;
After sawing, small defects often form that cannot be eliminated, so the wood has to be processed manually.

The sawmill works as follows:: a log is fixed on the platform, which remains motionless, and at this time the mobile cart starts moving and cuts the tree. The saw must be in a horizontal position.

To get boards as a result required size, the operator initially specifies required parameters. The saw blade acts as a saw, and it must be well tensioned.

How to make sawmills with your own hands

The most Common types of sawmills are corner, strip and chain., as well as devices assembled using a chainsaw.

Band sawmill

Collect band sawmill doing it yourself at home is quite difficult. This is explained by the fact that it is difficult to achieve maximum coherence of all its constituent elements in the process of work. In addition, you will need the necessary components and special tools, but the main thing is that you have the necessary drawings at hand. The finished structure must work with material whose weight is about three hundred kilograms. In addition, it is necessary to adjust the adjustment of the threaded thickness and observe safety precautions.

DIY sawmill assembly carried out on a site of the required size, which should be prepared in advance. The device will require special wheels and band saws. Then, in accordance with the drawings, the frame of the future unit is assembled. Work on the frame begins with the manufacture of special rails. To do this, you can pick up a corner and install one of the sides up. Then the wheels are installed, maintaining maximum strength.

Between two corners, set parallel, sleepers are made from a profile pipe, which are designed to ensure their reliable fastening to each other. To this profile pipe weld fasteners for logs that move freely in all directions. Then, according to the drawing, the cart is assembled and the wheels are attached to it.

Finally, the electric motor is installed, connected through a special pulley to the operating mechanism of the device.

Chain sawmill

The principle of operation of such a homemade product resembles a band sawmill, the only difference being that it uses a chain saw. The design of such a device is much simpler and smaller in size, which means that it is much easier to make it yourself. The chain sawmill is installed on a flat area so that it can be conveniently approached from any side.

Assembly of the chain device It begins with making a frame from a metal profile. Having assembled the main part, they make several technological holes, while maintaining extreme accuracy. The number of holes depends on the step length. Then they begin to assemble the racks and install the frame on them, after which additional stiffeners are made. This creates the basis of a chain structure.

In addition, it is necessary to assemble a movable cart for the sawmill with your own hands. To do this, prepare the base and attach the stop, gaskets, clamping plates and mounts for the electric motor to it.

Then the trolley is mounted to the frame, fasten the engine with the saw, tighten the chain and that’s it, the DIY chain sawmill is ready.

Corner or disc sawmill

If there is a need for radical cutting of boards, then it is best to use a corner or disk design.

Corner The sawmill has many functions and is used for large volumes of work. It is best to make such a design yourself, because finished equipment is very expensive. To assemble it, you should use the appropriate drawings, and before starting work you need to purchase all the necessary components and components.

First, a frame of metal pipes and guides are assembled high strength. All joints are fastened by welding. It is best to use rails as guides. Then the carriage is assembled. During assembly, special attention should be paid to the accuracy of all dimensions indicated in the drawing.

In the corner or disk sawmill is installed with a high-power gasoline engine, which effectively affects the process of sawing wood. The engine is mounted on the structure frame and connected to the working elements through special holes. Most often, a chain drive is installed on such sawmills, but in some cases this leads to overheating of the drive itself. When assembling the drive, it is necessary to pay due attention to safety precautions and eliminate possible risks during its operation.

Chainsaw sawmill

At home most often such a large sawmill is not required, therefore, the optimal solution in this case would be a mini-machine, which you can also make yourself. There are several types of mini-sawmills; they are small in size and, if necessary, can be easily moved to another location. Such a device is made using a chainsaw, which acts as the main element.

To make a mini sawmill from a chainsaw with your own hands, you will need:

two channels;
corners;
rails.

The work begins with assembling the frame, on which it is necessary to drill several technological holes. Then install the ties from metal pipe. Their fastening is carried out using fastening bolts in advance. drilled holes. During installation, be sure to control the angles between the elements: they must be straight.

To strengthen the frame, several stiffening ribs are mounted. Then the movable cart is assembled from a steel plate. Two corners are welded at the bottom of this plate, after which it is placed on bearings or rollers. Two corners are welded to the top of the movable cart, intended for mounting a chainsaw.
