How to make a sawmill with your own hands at home. How to make a simple band sawmill with your own hands - instructions, drawings and materials

The favorite material in construction, in the manufacture of utensils for the home and household, as well as a variety of decorative items, furniture, etc., as hundreds of years ago, remains wood. And the owner, who has the skills to work with equipment and skillful hands, can make a sawmill with his own hands. This will allow you to be able to harvest boards and other lumber on the spot according to your own needs, right size and type, and it will cost much less than buying finished products.

It is especially important when it is necessary to process a large number of boards and other lumber. Although it is generally accepted that the best option there will be a purchase of a finished device, but it is also possible and affordable to make it yourself 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 get a beautiful front lawn

Of course, you have seen the perfect lawn in the movies, on the alley, and perhaps on the neighbor's lawn. Those who have ever tried to grow a green area in their area will no doubt say that this is a huge job. The lawn requires careful planting, care, fertilization, watering. However, only inexperienced gardeners think so, professionals have long known about the innovative tool - liquid turf AquaGrazz.

When setting yourself the task of making a sawmill with your own hands, you should first of all determine the amount 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, which the best way suitable for the task at hand.

Maximum attention in the design and manufacture of a mini-sawmill should be given to safety - any equipment of this class is high-risk equipment and requires a very attentive attitude.

The presence of a sawmill is invaluable in the household of a master who often works with wood, because it will help solve such non-trivial handmade issues as:

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

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

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

In the self-manufacturing of a sawmill, both of these schemes are used, and its specific type is selected depending on the design planned for assembly.

If we talk about the varieties of sawmills, then the main ones are angular, tape, chain. Additionally, when it comes to home-made units, it is worth highlighting devices using a chainsaw as a basis. Each of listed species has a number of features and design differences from others, therefore, requires separate consideration.

Important! To manufacture a high-quality, reliable, safe and efficient unit on your own, you must not only carefully select the type, scheme, material and parts, but also work out and prepare drawings that you must strictly follow.

Band sawmill

The general principle of operation of a band sawmill is that the 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 stretched. By adjusting the height of the band saw, the size (thickness) of the sawn off part of the log (board, beam, etc.) is calibrated. Such a device can usually work with logs weighing up to 300 kg.

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

The assembly of the complex must begin with the preparation of a flat area right 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. As a rail, you can use the corner installed with the shelf up.

Between the two rails, sleepers from a pipe, channel or corner are welded in order to securely fasten them to each other. Mobile fasteners for logs are adapted to the sleepers, which must securely fasten wood of any (within the limits planned for processing) diameter.

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

It remains to mount the electric motor, connect it by means of a pulley to the unit mechanism and check the operation by starting.

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

Chain type installation

A do-it-yourself tire sawmill, according to its principle of operation, is very similar to a band saw, but it does not use a band saw blade, but a chain saw as a cutting element.

However, it should be noted that its structural design is much simpler, the installation itself is smaller, a smaller number of parts that require significant adjustment are used - this, in combination, makes the mini-tire sawmill easier to manufacture and use on its own than the band one.

The beginning of the manufacturing process also begins with the preparation of the work site on which the metal carcass 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 trolley is assembled on the frame by installing stops, gaskets, clamps and an electric motor. After checking the performance 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.

Angular disk minisawmill

A do-it-yourself angle saw blade is very useful in a home workshop for processing wood in different type lumber. Perhaps this is the most versatile and powerful mini sawmill - to make more complex structure will not work.

Important! The design of the angle sawmill is the most optimal for self-manufacturing- units of this class are very expensive and inaccessible. In addition, it is multifunctional and can process very large volumes of raw materials.

After preparing the drawings and acquiring all the necessary components and structural elements, it is necessary to prepare, as in previous cases, a site for installation. A base-frame is assembled on it, the material for which is taken metal pipes and guides of increased strength (the design involves heavy loads and the material must comply with them).

Guides for a mobile platform should ideally be made of rails, again due to increased loads. The next step to assemble the carriage should be different increased attention to the maximum compliance with the dimensions according to the drawing.

As a drive, it is recommended to use a high-power internal combustion engine (ICE) - this will increase the efficiency of sawing a large amount of raw materials and simplify work with dense wood varieties. It is best to use a chain as a 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 guarded or enclosed.

Chainsaw as the basis for a sawmill

A chainsaw is available from most craftsmen who work a lot with wood. Due to availability, low cost and simplicity, a sawmill can be made quite simply from a chainsaw with your own hands. There are a lot of options for a mini sawmill, the main element of which is a gasoline saw, but all of them are distinguished by simplicity, small size, mobility (it can be easily moved from place to place).

Important! In the vast 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, ease of maintenance, a do-it-yourself sawmill from a chainsaw is the best solution for your own household.

For the manufacture of a sawmill from a chainsaw, the following components will be required:

• channel;
• metal ceilings;
• rails;
• chainsaw as the main element.

At the place prepared for work, which, if necessary, needs to be leveled, a frame is assembled with holes for fasteners and screeds from metal pipes. Fastening is done with bolts. It is necessary to constantly control the angular dimensions so that exact perpendiculars (right angles) are observed. Additional stiffeners 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 underside. This base is mounted on rollers (preferably bearings). On the top of the plate, corners should be welded to which the chainsaw will be attached.
The last step is the installation of the structure for reliable fastening of the log when it is cut.

Modern sawmill production and private buildings require a disc or band sawmill with a margin of productivity and high technical specifications. Many advantages of these machines allow us to state with confidence that circular sawmills are the most successful solution for all woodworking industries, regardless of the scale of production and the range of products.

The purpose of the sawmill

Wood is one of the most sought after building materials. High strength and unique structure allow the use of wood in the construction of buildings, external and interior decoration premises. The scope and quality of this natural material depends largely on the woodworking equipment used.

A popular way of processing wood is sawing the material with the help of frame, band and circular saws. The disk design, for example, allows high-quality and fast roundwood to produce edged and unedged sawn timber, such as timber, boards and slats.

Disc units can be used for sequential processing of wood after sawing band saw and creating material from logs. Such equipment is different high level productivity, because rip cuts, edge sawing and splitting stand out among the design possibilities.

In the construction of wooden houses and in carpentry workshops, a circular sawmill is simply irreplaceable. It can significantly speed up and simplify the entire workflow, while saving a lot of time and effort. Without such equipment, the longitudinal cut of a large beam will take the owner more than one hour, but thanks to the sawmill, it will happen in a matter of minutes.

The design of the sawmill

A circular sawmill is a hardware machine that performs longitudinal sawing of trees and works thanks to an electric motor. Looking at the drawings of the sawmill, it becomes clear that the main structural elements are two engines, circular saws, movable operator's cabin, rail track and carriages.

The elementary design is a table on which a shaft with a disk is installed, its cutting part rotates above the plane. Such a simple design is suitable mainly for domestic use, and industrial production needs more sophisticated equipment equipped with discs that can change the sawing angle.

The main working element is a circular saw, which is usually installed on the machine spindle shaft or on the motor shaft. Each of the circular saws is driven by a separate engine, and their power does not always match. According to the device, circular sawmills are single- and multi-saw.

The metal frame of the sawmill is made of strong metal pipes and fastened by welding. For the carriage as guides, it is best to choose the highest quality rails without external defects, otherwise the carriage wheels will jump off or get stuck.

The carriage itself is assembled from metal parts. Rollers or wheels must fit perfectly under the rails. It should also be remembered that the frame itself, where the rollers are attached, must fit the distance between the rails very accurately. Only then will the movement of the carriage be free and smooth.

To equip the drive of a circular saw, it is customary to use any gasoline engine. It is desirable that the motor be more powerful, because it will have to work on two saws. In order to avoid overheating of the drive, it is recommended to exclude the chain drive from the design and replace it with a reliable analogue, so it will be possible to extend the life of the machine and secure it.

The principle of operation of a sawmill

The machine can work in industrial premises or logging conditions, i.e. inside and outside the building. The cut itself is made along a horizontal line by hand. Processing with a sawmill allows you to achieve flat surface trimmed tree. In addition, after watching a video about a sawmill, you will understand that the machine does not act up even in severe frost.

The main feature of the circular angle sawmill is the ability to cut in two directions at the same time: across and along the log. This is possible due to the peculiar arrangement of the saws - mutually perpendicular. Such a machine is suitable for working with any type of wood. The circular sawmill is capable of cutting logs with a diameter of more than 70 millimeters. The thickness of the cut in this case can be as little as 1 millimeter.

The transverse and longitudinal sawing of logs on such sawmills is carried out simultaneously while moving along the rail guides of the portal with saws. The movement of the portal for sawmills and carriages occurs with the help of an electric wire. The speed of the portal is regulated in steps, by means of a chain transmission.

The circular sawmill does not require installation on a special platform or foundation. The main thing is that the sawmill should be reliably protected from the effects of precipitation. It is also very convenient to use an electronic ruler when working with a sawmill, which allows you to adjust the cutting parameters in automatic mode.

Classification of sawmills

The circular sawmill is designed for sawing into all types of round timber - edged and unedged boards, bars and beams. The cut is made with a circular saw that has a diameter of 500-600 millimeters and is securely fixed on the shaft of the spindle unit, with the possibility of cutting in two directions and turning 90 degrees. Thus, circular rotary sawmills are divided according to the type of work.

Horizontal sawmill

One of the types of machines is a horizontal sawmill, which is quite common in the field of woodworking. Such a device has a collapsible design, thanks to which it can be easily transported to logging sites. When working on such a sawmill, there is a minimum of waste.

Sawing is done by a saw carriage running along the logs in both directions. The main advantage is that there is no idling. The sawmill uses circular saws with a diameter of more than 550 millimeters, made of steel with victorious teeth. Sawing due to such discs is very accurate, without the formation of wave-like depressions.

The operation of a horizontal sawmill does not require high qualifications, the machine is controlled by means of a remote control installed on the sawmill itself. With the help of such sawmills, materials such as edged and unedged boards, beams and slats are made. The productivity of these machines is very high.

Angular sawmill

The second type of sawmill is the angle sawmill. Sawing logs is done by the angular principle of sawing. There are two types of angle sawmills - with one and two discs. Look at the photo of circular sawmills: a single-disk sawmill unit feeds in two positions - vertical and horizontal, sawing does not idle and is performed in both directions.

The double-blade angle sawmill works by feeding the saw blades orthogonally. Disks are placed horizontally and vertically to each other. Double-disk angle-type sawmill shows high productivity of products even from one log. At large facilities, entire industrial sawmill complexes are installed, which perform the functions of sawing, cutting wood for lining or other material.

Manufacturing of a sawmill

When choosing woodworking equipment, you should remember that the price of a sawmill is quite high. Therefore, the acquisition of such a machine is often not affordable. This is especially true for young enterprises that are engaged in timber processing, and private craftsmen. But there is a way out of this situation, you can make a sawmill with your own hands. This approach allows you to save a lot of money and gain experience in working with woodworking equipment.

Today, it will be possible to make a home-made sawmill if there is a desire and minor skills in working with such equipment. You will need a sawhorse, boards and metal plates, fasteners (screws, nuts, screws), a tool for working with metal and wood, and an electric motor.

At the beginning of work, familiarize yourself with the design of the sawmill and recognize it distinctive features. As a working element of a circular sawmill, a circular toothed saw is installed on the machine spindle. There is an option to mount the saw on the motor shaft. At the sawmill, sawlog processing includes dividing and edging unedged board, as well as sawing blanks to the desired size.

You can preview the ready-made diagrams of a homemade sawmill and create your own mechanism drawing based on your needs. The simplest design of a sawmill is a table, under which a shaft with a saw is placed. Its cutting part rises above the surface of the table. The saw shaft is rotated by a motor through a belt-type transmission.

To make the base of the sawmill (table or bed), you can use ordinary wooden or metal goats, while tying them together with pieces of board. Attach a table to a similar base from above, which is made of steel plates that are about 200 millimeters wide and about 4 millimeters thick. The plates are connected with screws and jumpers between each other.

Sawmill discs are best made from steel or duralumin sheet, the thickness of which reaches 3 millimeters. In this case, the diameter of the disk should be within 500 millimeters. When creating a sawmill for cutting wood, the saw should have only 2-3 teeth. And such a disc will easily work with most breeds.

The main guarantee of high-quality work of a sawmill is the manufacture cutting teeth. The main requirements that apply to them are careful balancing and the correct cutting angle. Workpieces from which the teeth are easiest to cut are a broken drill or a carbide insert. The cutting angle of the teeth should be 30 degrees. The back angles should be at least 15 degrees. It should be remembered that if the cutters are poorly balanced, they will rub against the walls of the cut.

The cutting tool is attached to the table from below in such a way that the saw blade is clearly in the middle of the gap that is formed between the plates. Fasten the saw to the plane of the table through the holes made previously in the plates and the base plate. Holes made in the slab front side countersunk and assembled with screws that have a countersunk head.

In addition, when creating a sawmill with your own hands, the design of the guide is important. by the most simple option is a U-shaped saddle, which is formed from boards in the shape of a log, which is freed from branches and roughly processed with a planer. An engine with a saw is attached to the saddle. The motor power should be clarified: it should reach up to 2 kW.

The assembled table must be screwed to the frame with screws, and an insert with a slot for positioning should be inserted into the gap between the plates. saw blade. The thrust bar is fastened to the table with clamps when the saw is working. Subject to the above recommendations, a hand-made sawmill will delight you with the quality of its work.

Circular sawmill maintenance

Working with sawmills requires a certain skill. However, the maintenance of this machine does not cause big problems. To accommodate the operator, who cuts logs at the sawmill, a special cabin is provided. During sawing, the cabin moves simultaneously with the sawmill, so workers must constantly monitor the progress of the machine.

It should be borne in mind the fact that when working with a sawmill for safety reasons, a strong attachment of the device to the base is required, which should not be neglected in any case. Remember that in view of the design features on such sawmills, there is no idle reverse motion - in other words, when moving in the opposite direction of the portal, the log is also cut.

Now you have concluded for yourself which is better: buy ready-made woodworking equipment or ask how to make a sawmill with your own hands. Undoubtedly, a home-made sawmill is much cheaper than purchased in a specialized store.

Large-scale work using wooden beam or boards, such as the work of a carpenter or independent construction at home, are associated with the need for regular sawing of raw logs. Of course, you can buy ready-made lumber or purchase a sawmill industrial production, but it's expensive. This article tells (based on real experience) how a do-it-yourself band sawmill was made at relatively low cost.

It is quite possible to do and you will get robust design, which allows sawing a tree trunk into separate boards of three meters or more in length. You will need some materials (bars and parts of old machines), as well as to carry out locksmith, welding and turning work. Everything was planned to minimize the need for turning work.

To assemble the machine, old pulleys were taken, about 30 cm in diameter, dismantled from the Niva combine. Sawmill guides were made of two types of pipes: a half-inch diameter and a second, slightly larger diameter, such that they easily fit on a half-inch pipe with a millimeter gap.

At the first stage, you need to make "rails". For this, a 5 cm steel corner was used. It is installed side up, which requires very high accuracy in adjusting the wheels (poorly installed wheels will quickly wear out on the corner). Sometimes, to solve this problem, the corner is laid with the edge up.

The "sleepers" of this design were a profile pipe measuring 25x25 mm.

Between these profile tubes, a half-inch pipe is welded, and claws are already fixed to it - fasteners for a log. These claws bend and move freely, and when it is necessary to fix the log, several hammer blows are made on the clamps, as a result of which the locking mechanism self-jamming occurs.

When a band sawmill was made with their own hands, the profile tubes (“sleepers”) were made in such a way that they protrude beyond the rails. There are screws (M14 x 100 mm) on the protruding parts for adjustment. In addition, on profile pipes"bridges" were made - jumpers on which a log is placed before processing. In the case of workpieces of small length, the last two jumpers are installed at a distance of half a meter one after the other.

The pulleys were sharpened so that the worn belt protruded several centimeters. For the pulley housings, hubs from the Moskvich car were used, welded to the tubes.

All this together moves along guides - horizontally located half-inch pipes, and if necessary, with the help of bolts, this assembly is fixed.

When setting up pulleys, you may run into unexpected problems that require them to be cut and welded back on. This is due to the fact that in practice, the installation of pulleys "according to science", in parallel, leads to the tape coming off during operation. So, it is better to install them with a slight inclination, up to 4 degrees, then the tape in motion will “pull itself” on the rollers.

The driven pulley is the right one, it is tensioned automatically by a spring. In this case, a spring dismantled from the KaSika motorcycle was used. And the leading, left pulley is fixed rigidly, but it can be displaced if the size of the band saw changes.

Hardened rollers must be used in the sawmill. In the variant described in the article, a roller assembly was used, which is easier to do on your own and be sure of its reliability.

This assembly consists of three bearings on one axis: two - brand 202 and the third, standing behind, is 2-4 millimeters larger. The shaft with rollers is machined so that when changing the width of the saw, install washers between the bearings.

The shaft enters into two tubes: a half-inch and a second, into which a half-inch is inserted. In a half-inch pipe, the shaft is located with an axis offset, in fact, welded to the bottom wall. This entire assembly of shaft and tubes is attached to the guides in such a way that the roller assembly can be adjusted in height, shifted to the side, with different diameters of logs, and securely fixed after adjustment. From the side of the driven pulley, a dropper is installed on the roller, supplying a lubricating-cooling liquid (coolant).

The frame itself, one and a half meters high, is made of channel number 100, and for additional rigidity, the structure is reinforced with scarves. The cutting block can move along the channels by means of stud screws. A rigid fixation of the cutting unit in the sawmill is provided by bolts with a lock nut.

So, as you can see, equipment such as a do-it-yourself band sawmill can be made even in a small home workshop or garage. Thus, a carpenter or a summer resident will have the opportunity, right at his site, to dissolve large blanks on boards for his needs or even earn a little - take orders for sawing logs.

A few more options for the working units of the band sawmill:

DIY band sawmill video

Dear site visitors « from the presented material you will learn how you can independently make your own band sawmill. Every craftsman dreams of having his own sawmill on his farm, because its presence will reduce the cost of lumber tenfold. With the help of this machine, you can dissolve the logs into boards and bars yourself, it is also an excellent option and, that is, boards can be produced directly at the construction site of the future house. It is also possible to open your own private sawmill and dissolve the boards already for money and replenish the family treasury extra income. In general, the machine is very good from all sides, and its self-assembly will again cost much cheaper than the factory counterpart, because many spare parts can be used used and available to the motorist, for example: wheels from a car, hubs, bearings, bolts and other things that you can get in the garage)

The design of the band sawmill consists of 1. rail track 2. frame with a power unit 3. blade 4 adjustment and tension mechanisms 5. carriage 6. flat surface (preferably foundation plate)

And so, let's get acquainted with the list of necessary components for assembling the machine. We will also analyze the whole process step by step.

The process of assembling a band sawmill.

And so, the first thing to do is to get acquainted with the drawings, because any business begins with markup, as they say, “Measure seven times, cut once.





So we got acquainted with the drawings, and now I also want to note that there are several types of home-made sawmills

1 Band sawmill with electric motor.
2. Band sawmill with gasoline engine.
3 Tire sawmill. Principle of operation tape machine for cutting wood. The blade is stretched over 2 horizontally located pulleys, in this case these are ordinary automobile wheels with a tire and a chamber, an indisputable advantage of this design is that it is possible to tension the saw by inflating tires. The limiter and supporting rollers are located directly at the bottom.
Well, I hope the principle of operation is clear, then it’s worth taking care of placing the railroad along which the carriage with the saw blade will go and dissolve the logs on the boards. The site must be at least 3 x 6 m in size, and most importantly, flat! Therefore, it is necessary to pour a foundation slab under the sawmill and level it to a perfectly flat surface. A recess is dug, a sand cushion is laid and a reinforced concrete slab is poured.
Next comes the installation of the railroad itself, at best it can be made from narrow-gauge rails railway, but this is difficult to get, so you have to make it from a channel or a corner. Note!!! In the photo, the corner is located with an edge up.
You can connect the corner to each other by welding, but when the metal is heated, it can lead, and we need a perfectly flat road, you can also attach the rail directly to concrete base with anchor bolts.
Support rollers can be made from ordinary bearings, or ordered from a familiar turner.
After that, the saw frame itself is made directly, where pipes of different diameters are used that can be inserted one into the other. whereby the slider can move up and down.
The frame is welded from a square-section professional pipe.
Support rollers are installed at the bottom. they must match the width of the railroad.
Next, the lifting mechanism is made.



After that, pulleys and hubs are installed.

Connection to the power unit.
Alignment and support of the saw blade is carried out by bearings.

From above it is mandatory to install a protective casing made of metal. Safety is paramount here, because the canvas can fly out.
The tension mechanism can be made from a small jack.
After the complete assembly of the sawmill, a test run is carried out, if everything is in order, then the engine is turned off and the log is laid and fastened.

The log is unraveled on the boards. You can also see the work of the sawmill clearly in the video.

Here is such a wonderful sawmill, in general, it turned out, now dissolve the boards and bars for construction and repair as much as you like, just have time to throw logs)

Thank you very much for your attention!

People who live outside the city often want to purchase a sawmill. With the help of a similar design, you can get timber and boards at an affordable price. It should be understood that wood is the main material for construction, so you can earn money with the help of a sawmill.

The sawmill is used for sawing trees for their further use in construction.

How to make a sawmill with your own hands

If it was decided to install a frame sawmill, then you will need to buy it or do it yourself. In this case, everything will depend on how many cubic meters of wood are planned to be processed. To accept the right decision, should be familiar with existing varieties saws and learn more about their characteristics.

The device of a collapsible sawmill.

Elements that will be needed in order to make a homemade sawmill:

• Electrical engine;
• metal profile;
• corner or pipe;
• tire or disk;
• dowels.

Varieties of sawmills

Consider existing species sawmills, in which the base is the frame. Ordinary factory frame structure is an expensive equipment that has a high performance. In the yard of an ordinary farmer, it makes no sense to install a structure of this type. If it was decided to install such a device, then it is best to purchase a finished model. The cost of such structures is 500,000 rubles. and more.

Today there is a large number of various equipment for sawing wood. However, most designs are not suitable for a small backyard. Such structures can process several thousand cubic meters per day. For small areas, these types of sawmills are suitable: tape, disk and tire.

The most profitable option is a band sawmill. It will produce the minimum amount of waste. In addition, such a device is unpretentious to weather conditions. However, this is quite difficult to do. It is recommended to use it for processing wood with a diameter of up to 7 cm.

In most cases, circular sawmills are used. The main advantages of this cutting technology are the following: simplicity of design, reliability and wide functionality. Disadvantages include high cost good quality and a large amount of waste generated when compared with a band sawmill design. It should be noted that at home the amount of sawdust does not matter, since small volumes of sawing are implied.

Tire small design is a sawmill, which is most often used by novice craftsmen. Such a technology can give excellent results of wood processing if good quality wood is available. This design is the easiest to create with your own hands.

How to make a sawmill yourself: a sequence of actions

First of all, you need to draw up a plan for the construction of a sawmill. If you plan to use the structure for the purpose of making money, it is recommended to purchase a ready-made sawmill.

Do-it-yourself creation makes sense only if such a device will be operated intermittently.

You can also make the design yourself if there is at least a small amount of materials that will be needed (engine, metal profile, etc.).

At homemade sawmill performance will not be as high as that of the finished design. If you need to make, for example, a floor board, then you can use and.

First of all, you need to determine your needs:

1. Performance. How many cubic meters of wood are planned to be processed daily.
2. Planned thickness and length of lumber.
3. Place of installation (stationary or need to move the structure).
4. Energy type (electrical or gasoline).

Based on these characteristics, it will be necessary to select the materials and type of saw frame device. Such a construction is arranged as follows:

1. First of all, you need to make a base, bed and frame. Regardless of what type of sawmill is planned to be produced, the frame must be reliable. The quality of the cut and the safety of the users of the device depend on these indicators. The overall length will be determined by the length of the logs to be sawn. In order to make guides, you can use a corner, a pipe and other materials. Thickness sheet metal determined based on the planned weight of the round timber. For a carriage with a saw, you can use metal with a thickness of 3-4 mm, the structure can easily withstand the weight of the engine and fittings for sawing.
2. Engine. In this case, everything will depend on financial capabilities. If there is a three-phase electric motor with a power of 3 kW or more, then it is recommended to install it. If there is an amateur chainsaw, then it will be possible to adjust the carriage for it. chain electric saw must not be used, as its engine is not intended for this type of work. A household chainsaw cannot be used either, as they have little power. The latest designs quickly fail under significant loads.
3. Structure for fixing logs. Such a device is recommended to be made stationary, its height should be small. The thickness of the metal depends on the weight of the logs to be cut, so everything will depend on personal needs. The easiest way to work with hardwoods.
4. Tire or disk. The length of such elements is 45-50 cm. Today, tires can be found on sale. special kind, as well as chains with a small thickness of cut. If you use such elements, you can significantly reduce the amount of waste. The chain will also need to be purchased special, the angle of its sharpening should be equal to 10 °.

Do-it-yourself sawmill: an example of manufacturing

As an example, a sawmill with a disk will be considered. The carriage is located at the top of the structure. First of all, you need to decide on the guides, which should be used as metal corner 5 cm, the length of the rail should be 5 m. The sawmill will be stationary. With a gap of 15 cm, you need to drill holes in the corner and concrete. The structure can be fixed to the floor with dowels.

A device for fixing logs is made of a profile in the shape of the letter P. In this case, you can also use a channel, the extreme parts of which are welded to a metal corner. In order to fix the log, it is necessary to make holes in the profile for the fasteners. The maximum thickness of the logs is approximately 40 cm, therefore, distances of 10, 15 and 20 cm must be measured from the central part of the profile. At these distances, it will be necessary to make holes for the stops. To produce reliable connection, on the profiles you will need to install a moving device for fixing with teeth. It can be made from a piece of metal sheet 4 mm thick. With the help of a grinder, you will need to cut a small number of teeth. It is worth noting that two teeth are enough for the log to be securely fixed and unable to move. Next, you need to drill holes in the profile and the device for fixing. With the help of cotter pins, you can easily dismantle and mount the fixing device.

After the frame is made, you can proceed to the production of the carriage. In this case, a three-phase motor with a power of 3 kW is used, so you need to make a reliable design. The height of the carriage will be 1.1-1.2 m. You will need to mark a corner of 40 mm, which has a thickness of 4 mm. In this case, you can use the profile.

The device must be cut into several elements. The carriage will have a welded structure, therefore all elements should be connected. At the ends of the corners of the carriage, you will need to drill holes for the wheels. At this stage, the carriage frame is ready.
