We make a homemade sawmill with our own hands. Do-it-yourself band sawmill? Why not! Homemade band sawmill

Wood is widely used in everyday life in the production of various structures, their finishing and other work. Owners of private land constantly conduct construction works: build an extension, update the fence, increase the reliability of structures, and so on. The ease of workability, as well as the availability of wood, initially determined their popularity. Many owners of private houses and plots have determined in their own practice that purchasing logs and getting boards, beams, and edges from them is much cheaper than buying ready-made lumber. Also, do not forget that sometimes the length and thickness, width of the boards or timber used are important. Therefore, making them yourself can significantly reduce money and time costs.

A band saw is often used to obtain lumber from a log or other piece of wood. The popularity of this equipment has determined the emergence of a huge number of different machines, some of them compact and designed for installation in a home workshop. However, the cost of household options is quite high; it is advisable to buy them only in the case of continuous production of lumber or other wood products. This is why many people decide to do homemade design. Band sawmill it is created with your own hands within a short period of time, for which you should know: what parts are needed for this, how the assembly is carried out.

Cost and efficiency of industrial options

Why there is a great desire to create homemade version execution of the machine? An example is the Taiga band sawmill, the cost of which, depending on its performance, can vary between 112-165 thousand rubles. Even the simplest version, which does not have great performance, will cost at least 90 thousand rubles. A homemade band sawmill will cost several times less. A self-made machine is suitable for occasional use.

Difficulties in making a machine yourself

The structure of a band sawmill is quite complex. The performance of the band sawmill, service life without breakdowns, and much more depend on the quality of the assembly. You should start making your own machine after considering the following points:

Installation work is carried out using welding. Therefore, without welding machine It is practically impossible to carry out work on creating a frame and other elements. To change the shape and size of structural elements you will need a power tool and a milling machine. Of course, the creation of some elements can be entrusted to professionals, but this will significantly increase the cost of the work.
During operation, a large load is placed on the band sawmill. Therefore, the structure must be stable and durable. To do this, the structure is attached to the base, and the frame and other elements are produced taking into account the possible weight of the processed logs, about 300 kilograms.
If you are creating a homemade gasoline band sawmill, then you should take into account the need to carry out work on sharpening the saw and routing the working part.
There are quite a lot various designs, which allow you to indicate the thickness of the resulting product.
It is necessary to consider the safety of using the equipment. The installed saw and tape can cause significant harm to human health.

It is worth considering that the design of homemade band saws is only suitable for cutting boards of various lengths and widths.

There is enough a large number of options for homemade band sawmills, the drawings of which are based on the use of electric and gasoline engines. At the same time, electric versions are very popular due to better performance and ease of use. But not in all cases it can be used Electrical engine as a driving force, since not all plots of land have electricity.

Conduct a review of specific machines, the drawings of which have exact dimensions. After all, each production requires a table of different sizes, as well as an electric motor of different power.

The procedure for making a homemade band sawmill

The above points indicate the main points for the production of a homemade sawmill. You can make a band sawmill yourself with minimal cost. After all, you only need to buy or find an engine, pulleys and rollers, find a metal profile for the frame and a blade for sawing. The reliability of the design depends on the technical condition of all components and the quality of their connections. Therefore, before using the sawmill, you should check it carefully.

Allows significant savings if there is a need for constant processing of wood 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 the maximum size of the log.

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, so further processing of the wood is done manually.

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.

To end up with a board the right size, you must 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 set 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 movement 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 further 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 a 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 whose internal diameter does not exceed 35-40 mm, since movable rods will be installed inside.

Clamps must be placed on top of the pipes. The metal corner is the material from which the 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 placed. 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 provide 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 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 work 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 a 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.

Wood is widely used building material, especially for suburban housing construction. And very often sawmills come to the aid of builders different types. Today we will look at what a homemade band sawmill is, which can process wood of different species.

You will see a video of a homemade band sawmill on the topic of its assembly and learn what the advantages of this device are and how to make it at home.

Advantages of a homemade band sawmill

The band sawmill is universal in terms of the fact that it can work with different tree species and process them into products such as:

veneer;
boards;
bars;
shields;
furniture accessories, etc.

Homemade band sawmill weighs on average one and a half times more than the material being processed, so the workpieces with its help are high-quality and durable.

Sawing wood on a band sawmill is much easier than on other types of this unit. Thus, sawing can be performed taking into account the characteristics of each wood, and the amount of sawdust will be minimal.

Band sawmills have the following advantages:

To make a homemade band sawmill, you The following parts will be required:

rails;
steel corners;
channels;
bolts;
pipes;
electric drill;
clamping plates;
boards or bars;
hairpins;
braces;
chains.

To have a clear idea of the process of assembling a band-type sawmill with your own hands, we recommend watching a video on this topic.

Unit design features

You need to know the design of a band sawmill if you are going to assemble it yourself. Her the scheme is organized according to the block principle, which allows for different layouts. At the same time, it may be simpler, or it may be more complex. Complex design includes automatic feeding saw, a device for determining cutting thickness, current load, as well as elements for feeding saw logs and others.

The nodes of the band sawmill are as follows:

The frame of the sawmill consists from several welded soles where the rollers are located. The frame in the shape of the letter “P” consists of channels placed parallel and fastened to each other. The driving pulley is mounted on the end of the frame, and the driven movable pulley is mounted opposite, respectively.

In the middle of the frame there are collapsible type guides on brackets. They include several sections and are easy to transport. At the bottom there are support rollers where the anchor bolts are screwed in, and at the top there are log supports. The guides are attached using a channel beam where the coupling device is located. It also helps to move the sawing device. The log is secured to the rails using screw clamps and stops.

Mechanism of sawmill and rails allows you to adjust the logs along the width of mutually placed guides, even if the frame is damaged. The guides are hung so that they do not depend on each other, so if a large log falls, the frame will remain intact. And to make the rails longer, you need to attach a section to them.

For cutting and processing wood, a saw with a width of 60 mm or less is used. And the saw of the band sawmill is tensioned by means of a spring-screw mechanism. There are locks in the front beam and driven pulley sliders to help you install and remove the saw band.

What should you consider before assembly?

Before work, consider the following nuances:

Stages of assembling a homemade band sawmill

For the base of the sawmill frame we will need channels 8 m long and 140 mm high. You can use several rails with the sole facing up, as well as steel corners measuring 50 by 100 mm. All workpieces must be straight.

The work stages will be as follows:

drill a small number of holes at a height of about one and a half meters along the entire length of the channels. In the same quantity, make ties from pipe sections 250 mm long. To fasten channels and ties, take threaded rods or bolts about 300 mm long;
mount the guides on racks assembled from channels and bolted together. The number of racks depends on the length of the bed. If it is 8 meters, then there should be 4 of them. They need to be placed 100 cm from the end of the guides;
To give the frame additional strength, install braces. The structure is assembled on site because it has an impressive weight. To give the guides a horizontal direction, you need to place bars or boards under the racks. Also, if necessary, you can dig up the soil;
we assemble a movable cart based on metal plate 45 mm thick. Its length should be about 60 cm, and the final calculations depend on the dimensions of the electric motor. The width should be such that the edges of the trolley extend beyond the channels on all sides by approximately 80 mm. Plates and spacers of varying thickness will help move the cart along the length of the guides;
When assembling the sawmill, make sure that the gap is as small as possible. Also, the gaskets should be approximately 0.5 mm thicker than the channel flanges. The gaskets and clamping plates are attached to each other using special bolts. And in order to prevent lateral play, plates from the bolt side must be screwed to the base of the trolley;
The trolley can also be installed on bearings, and at the top of it you need to place corners for attaching an electric motor.

Installation of key components of a band sawmill

To move the trolley with a circular saw together with the engine, you will need a special chain. It is tightened in order to eliminate free play, which is installed on one of the bushings on the sprockets along the edges of the guides.

One of the advantages of a homemade band sawmill is the provision of comfortable work by equipping it with a mechanism for securing logs. Such mechanisms are made on the basis of pipes with a diameter of about 40 mm. We insert movable rods into these pipes, place clamps at the top based on an angle measuring 40 by 40 mm and cam clamping fixtures. In relation to the existing distance to the sawing line, the length of the clamps should be from 15 mm.

Install the main components of the sawmill:

electric motor;
file

It is advisable to purchase an electric motor with a power of 10 kW for the device, and the file should have a diameter of one meter. If you cannot find these elements according to the given parameters, then the bed should be smaller. remember, that component size influences the size of the future sawmill.

As you can see, assembling a band sawmill with your own hands is not so difficult if you understand the design features of this device and have all the necessary components for work on hand. And its high-quality implementation is the key to successful operation of the device.

Not everyone can afford the purchase of a ready-made sawmill, especially since it will only pay off with constant use (read commercial use). Is it possible to make a sawmill with your own hands? What difficulties will a do-it-yourselfer face if he decides to cut raw logs into industrial wood on his own?

Homemade band sawmill

Let’s make a reservation right away – making a band sawmill yourself is very difficult. It's not so much about the components, extensive turning and welding work, the need to sharpen and set the saw in a special way, but in the smooth functioning of the entire complex.

It is necessary to ensure loading and stability of movement of up to 300 kg of one log, adjustment of cutting thickness, and most importantly, safety precautions. But if the availability of free wood wins, we make a band sawmill with our own hands.

Let us explain the principle of tape cutting with an example: take two spools of thread, stretch a threaded thin tape between them. By forcibly rotating the belt, we cut the log, the distance between the belts is maximum size timber. Band saws are convenient for cutting boards.

We start with choosing a production area or premises - at least 3x6 m, verified. Second in importance - metal wheels carts and band saw, this must be found or purchased. Order the frame of the belt mechanism with wheels, or it is better to buy a ready-made one. Self-production requires skills and a lot of high-precision tooling.

View 2: 1 - pulley for starting the motor (if a three-phase motor is connected to single-phase network); 2 - engine; 3 - pulley; 4 - shaft; 5 — housing with bearing; 6 - base; 7 - flywheel; 8 - finger; 9 — connecting rod; 10 - saw; 11 — M14x2 screw; 12 — roller; 13 — guide angle; 14 - stand; 15 — steering wheel; 16 — bushing; 17 — asterisk; 18 — nut M14x2; 19 — lock nut; 20 is an asterisk.

We install guides - any durable one smooth metal: I-beam, channel, angle, under them, through 0.5 m, a support or anchor for stability. The distance between the guides is the diameter of the big log with a margin of about 0.7 m. Maintaining the geometry, we weld everything together. We attach wheels, a belt mechanism frame, and an electric motor through a pulley to the cart.

Think over the mechanism of change horizontal movement saws relative to the log. Moving the cart relative to the fixed log, we cut off a horizontal layer of wood - we make boards.

Disc sawmills have received the greatest handicraft use due to their versatility and ease of manufacture. We will make a circular sawmill with our own hands. The most important thing is that we will need a circular saw - a disc larger than 500 mm (the larger the better). The propulsion device is usually an electric motor through a pulley that increases the speed.

A welded frame is prepared, a metal (less often wooden) plate with a slot for the disk is placed on the frame. The gaps between the disk and the plate are minimal. The saw shaft is attached to the plate from below on bearings and a pulley. The electric motor pulley and the saw are connected by belts (reinsurance when the saw jams) - a homemade circular sawmill can work!

one of the options for a homemade circular sawmill

To tension the belt, use the weight of the engine with the addition of weights. Make the supporting platform of the electric motor movable coaxially with the saw shaft, deflecting under weight in the opposite direction. The wheel of a working tractor with a drive to a saw pulley without belts is often used as a propulsion device.

The principles of cutting are the same as in strip cutting - we feed the log to cutting disc. After a disc cut, the surface of the lumber is of higher quality due to the speed of processing. Disc sawmills come in vertical and horizontal types - they are easier to use in mobile installations.

Tire sawmill

We need to start by understanding what and how much we will cut. If you need to cut 100 - 200 rafters for a house being built from free logs, then 400 boards, it is better to use a hand-held professional chainsaw. Let's do it homemade sawmill from a chainsaw, the method is inexpensive, simple and effective.

drawing the simplest sawmill from a chainsaw (download full drawing)

You will need any smooth metallic profile, welding and grinder. We start with the maximum length of the log - practically about 4 m. For this length you need to find a channel or I-beam, you can weld it from pieces with reinforcement - the main thing is that the resulting profile is even. We are starting to make our autonomous sawmill based on a chainsaw.

The design is a powerful profile on working height– above the belt along which the attached chainsaw moves in the cart.

The height is determined by ergonomics; a prolonged knee-elbow position is not useful. A log is placed parallel to the main profile on a support frame, a running chainsaw moves along the log and makes the necessary trimming.

A few more details about the features. Main element– main profile, providing geometrically correct sizes lumber, must be sufficiently strong and rigid, if the channel is at least 200. The profile rests on 3 or more supports connected to the support frame on which the log rests.

If you decide to do chain sawmill do it yourself - be sure to look at the LOGOSOL sawmills. Drawings and documentation can be downloaded from the website and used as the basis for your homemade project.

The main errors when sawing are formed when the cart with the chainsaw oscillates, so the movement of the cart along the profile requires at least four firmly pressed metal wheels, it is necessary to provide manual drive. The simplest is a well crank with a drive wheel along the main profile.

To install a heavy log, slopes are usually installed along which it is convenient to push the log successively from side to side onto the support frame, wedging it on the frame.

The most difficult thing is the adjustment mechanism for the thickness of the product. The simplest way– installation along the edges of the movable vertical plane supporting frame screw or any rigid fixation jacks. We adjust the jacks - we adjust the thickness of the product. Example of mobile phone construction tire sawmill based on a chainsaw can be seen in the photo.

Cutting wood can be done by one person: holding the chainsaw handle and adjusting the gas, we feed with the other hand.

Conclusion

A few thoughts on the feasibility of making a sawmill. Tested by time and practice - self-production makes sense with free materials. If you calculate the labor costs and materials, and the possible benefits, you will understand for yourself. The worst thing is when self-production– few people pay attention to safety precautions. This moment definitely needs to be thought through! Trouble-free operation and high-quality wood.

Nowadays, you can increasingly meet people who prefer wooden houses. That’s why construction crews use different types sawmills But in Lately Band sawmills are becoming the most popular, as they have a lot of positive qualities.

Features of wood processing with a machine

From time immemorial the tree has been considered natural material, which even our ancestors used. But technological progress does not stand still, and people have come up with a large number of machines for processing wooden materials. One of these machines is considered to be a band sawmill; by the way, it is an indispensable attribute for those who want to build wooden house or works with such material constantly. So, the sawmill perfectly replaces the usual plane for everyone.

Even if after construction wooden house you won’t need it, then the machine can generate income. After all, you can accept orders for sawing wood, sawing logs and manufacturing various wooden blanks. Experts have invented a sawmill that can work with various types wood, namely deciduous and highly resinous. She processes them so that boards, timber, veneer, carriages and other types of blanks are obtained.

A homemade band sawmill is often used to make blanks that will later be used for the production of furniture, panels and laminated veneer lumber. The machine itself is quite heavy, its weight is 2 times the weight of wood, so you can produce higher-quality lumber and use the machine longer.

Sawing logs on a homemade band sawmill has a greater advantage than on others, since the work is made easier. On others tape machines Before moving on to the process of sawing wood, it is necessary to take into account the characteristics of each log. And if sawing takes place on a band sawmill, then the loss of wood is minimal.

The advantage of such a machine is high-quality wood processing, compactness, reasonable price, lightweight design, low weight, ease of installation and transportation, economical operation. And most importantly, it consumes a small amount of electricity.

The operating principle of a band sawmill

The entire work process consists of three stages, namely:

We prepare the material, that is, logs. You can take logs different sizes, but then they must be pre-prepared so that after processing all the material looks the same.
Now we begin the wood processing process. To do this, you need to set up the machine, following the instructions, and then set the program, and the equipment does everything for you.
The final point: if we see any errors, we process them ourselves.

The principle of operation of such a machine is that sawing occurs wooden beam in a stationary state under the action of the moving saw blade. It is fixed on the driving and driven pulleys and tensioned with a force that ensures straight cutting.

We place the log on the machine between two guides and secure it with movable supports.

We set the thickness of the wood ourselves; for this, an electronic ruler or hydraulic mechanism on the machine.

But you do the sawing, laying, clamping and turning of the material yourself.

In order to prepare the sawmill for work, it is necessary to sharpen the saw and set the teeth apart. It is important to remember that for different wood You need to carry out the process of setting the operating speed yourself.

The entire structure is made using a traveling path and the direction is in one direction, thereby regulating the process, even through mechanical deformation. To ensure the required size, you need to monitor the dimensions of the material being processed.

The stability of the position of the saw blade is ensured by fastening the stabilizing rollers. The first roller is responsible for the immobility of the drive pulley, and the second moves along the guide, thereby providing a free section of the saw. At this moment, the saw is fed and the log is sawed lengthwise.

How to make a band sawmill with your own hands?

If you urgently need a band sawmill, but the factory price does not suit you, then you can assemble it yourself.

To do this you need to know a few nuances:

The basis of this design is two channels, which should have a length of 8 m and a height of 140 mm. For this purpose, you can use two rails, but they must be with the sole up, or corners 50x100 mm. No matter what material you use, it needs to be straight.
After you have decided on the material, you need to drill holes, they are made at the same distance - in increments of about 1.5 m. Then we proceed to make the ties, that is, we take pieces of pipes of the appropriate diameter, the length of which should be 250 mm. To connect everything, we additionally take threaded rods or bolts, the diameter of which is 290-340 mm.
Once everything is assembled, we proceed to installation on the racks. The number of racks is determined based on the length of the bed. For example, if its length is 8 m, then their number is approximately 4 pieces. The end posts should be installed at a distance of 800-1000 mm from the edge.
Next, the band sawmill is made with your own hands as follows. To make the frame rigid, you need to additionally install braces. But remember that all this weighs a lot, and must be installed on site. In order to ensure a horizontal direction, you can additionally dig up the soil or simply lay down boards or bars.
Now you need to install the movable cart, which is usually made of a steel plate. Its thickness should be 46 mm and length 600 mm. True, such parameters directly depend on the size of the electric motor.
Now, you need to pay attention to the gap - it should be minimal. The thickness of the gaskets should be greater than the thickness of the channel flange. We clamp the plates and gaskets using M8 bolts in the amount of 8 pcs. If possible, the trolley should be mounted on bearings or rollers. Two corners must be installed on top - this is necessary for attaching the electric motor.
To allow the cart to move with circular saw and the engine, an additional chain is needed. It is tightened so that there is no free play at the helm. AND final stage- this is the installation of sprockets at one of the bushings, which are located along the edges of the guides.

The main elements of a band sawmill are the motor and the saw. Therefore, try to purchase a motor with a power of at least 10 kW, and a saw with a diameter of 1 m. If you cannot purchase such a motor and saw, then we make the frame smaller.
