Okay google homemade band sawmill. Do-it-yourself sawmill at home: disk, belt, tire

Today you can buy a home sawmill on any construction market. However, such a device is not very cheap. Therefore, home craftsmen, having studied all the intricacies of this device and looked at the materials given on the Internet, produce homemade mini-sawmills. To do this you need to have the appropriate material and plumbing experience.

To work you only need to use quality material, since if the frame is made of thin pipes or small corners, it may fail. The worker may be seriously injured.

Where to start the work process

To set up any type of mini sawmill you need to have following materials and tools:

• channel;
• pipes;
• sheet steel;
• metal corner;
• bars;
• Circular Saw;
• electric motor;
• welding machine;
• drill;
• bolts;
• spanners;
• pliers.

Of course, the productivity of factory samples of a mini sawmill is much higher than a home-made device. And yet, homemade products contain the most necessary properties, which suit a particular owner. Before you start making a mini sawmill, you need to determine future parameters:

1. It is very important to calculate what performance the device will have. To do this, you will need to determine the volume of wood that will need to be processed.
2. Approximate dimensions of workpieces.
3. Transportation methods. It is possible that the frame sawmill will have a stationary appearance.
4. Power supply: gasoline or electric.

Mini disc sawmill

A sawmill that is engaged in a particular type of business most often uses a disc sawmill. This is the simplest type of device and is easy to make yourself. For this you will need the simplest preparations.

This mini disc sawmill is fundamentally different from similar devices. The basis of the entire structure is a circular saw. It is secured in two ways:

• on the spindle shaft;
• on the axis of the electric motor.

The simplest form should be:

• table;
• circular saw;
• engine.

The basis of the entire structure is the table. A frame is made for it from metal corners, bolted or welded. The top of the table is a steel plate with dimensions 200 x 4 mm. Sometimes such a plate is made as a team. All parts are fastened together with bolts and nuts.

Note that the base of the mini sawmill can be made of wood or metal corners. A base made of thick boards is worse than a steel one in only one case. If the sawmill is constantly under open air, then the boards will quickly rot, even an antiseptic will not help. All other qualities are superior to the iron base, since it is very easy to process wood on solid boards.

To secure the saw, the plates have a special hole into which the circular saw is inserted. The holes made in the table are countersunk and then bolted together. The saw must be fastened so that it is strictly in the center of the entire structure. It is attached through the holes in the plates and table.

How does a mini sawmill work?

The main parts of the bus mini sawmill are:

• bed (frame);
• drive unit;
• fastening parts;
• tire together with the chain.

The frame is the most important detail. This is the basis of the device that holds all the equipment. The safety of the work and the final result of the entire operation largely depend on the reliability of the frame and its stability. The length of the frame is selected individually. This value is directly dependent on the dimensions of the workpieces being processed.

The strength parts of the frame can be:

• corners;
• channel;
• brand

The thickness of the shelf of such fasteners should be above 3 mm. This size can withstand heavy loads.

Motor. Without this part, the mini sawmill will be dead. For a home sawmill, it will be quite enough to install a powerful three-phase electric motor. Even a professional chainsaw can be suitable for this purpose. It is easy to attach to a moving carriage. Electric saws are not suitable for this type of work; they have too little power.

Fasteners For sawing, the log must be secured to a stationary device. The choice of hardware depends on the mass of future workpieces. It must be possible to quickly attach.

The tire usually has standard sizes- 50 cm.

It is better to buy it together with the chain. This device will allow you to get minimum thickness cut, which means waste is minimized and the efficiency of the sawmill will increase.

You can make a saw yourself. To do this, you need to resharpen the blade of a mechanical hacksaw designed for working with metal. The dimensions of the canvas are 40x450 mm. Tooth cutting is performed cutting disc special angle grinder. The teeth are set pointwise after preheating with a welding torch. The sharpener will help create the required shape for the saw. The original teeth that are left untreated can be left.

DIY chain sawmill

A home sawmill consists of several main parts:

• frame;
• guides;
• engine.

To make a sawmill with a bar chain, you need to fasten the steel frame together with the saw bar. The distance from the tire to the frame corresponds to the thickness of the workpiece being processed. Therefore, such a thickness must be foreseen in advance and included in the drawing of the chain sawmill.

If you make an adjustable distance from the tire to the frame, you can cut the most different boards, with different dimensions.

The base must have guides along which it will move in the vertical direction. To attach the base to the posts, plates with holes are welded. After installation the right size the base is fixed with bolts and nuts.

When selecting an engine, it is necessary to take into account its power. It must be at least 3 kW. The motor should operate in the most economical mode.

It is difficult to answer how reliably and efficiently a home-made sawmill will work. It all depends on the homemade “Kulibin” and his skill.

The most important requirement for structural reliability is rail guides. If ignored, the design will be unreliable and dangerous. It is especially important to have an accessible and easy-to-use mechanism that secures the logs.

When carrying out construction or carpentry work Lumber is always needed. These can be boards for various purposes, timber for foundations and floors, parts of building structures.

To have sufficient stock necessary materials, you will have to frequently saw untreated logs. Of course, you can already buy finished products, but financial costs will increase several times.

A factory-made sawmill is also not cheap. However, you can make a fully functional sawmill with your own hands at home, and the costs will be significantly lower.

Varieties

Depending on the design of the working part, a homemade sawmill is made of three types:

• disc sawmill;
• tape;
• tire

Let's take a closer look at each of them.

Disk installation

Among homemade devices Disc sawmills are the most common type. They have gained wide popularity due to their versatility and ease of assembly.

Most suitable for one-time construction work or for small businesses that do not involve large volumes of production. The basis of this design is a circular saw mounted on an electric motor or on a spindle.

In most cases, a so-called “circular” is made - solid foundation in the form on which the engine and the shaft with the circular saw are mounted.

The base is made of wooden or metal parts, which are fixed in a crosswise position and secured with a board of a suitable size. Metal plates are fastened on top of the board using bolts.

In the resulting plate it is necessary to leave a slot for the saw and holes for mounting the engine. The holes must be additionally countersunk and then secured with screws.

The saw must be installed strictly in the middle of the resulting structure. The top plate is connected to the base with screws, and the disk insert is fixed in the hole between the plates. The last thing to attach is the thrust bar.

note: when assembling the sawmill, close attention should be paid to the reliability of fastening of all structural elements. An insecure saw blade poses a serious threat to human health and life.

Using a homemade circular sawmill you can make beams, slats different sizes and veneer. The rotation speed of the saw is sufficient to obtain high-quality products with smooth edges and cuts.

Belt type

Installations using band saws are used in the production of lumber on an industrial scale.

Private production in most cases is equipped with homemade sawmills, made on the basis of drawings of factory units. The main advantage of such devices is the ability to quickly cut large logs weighing up to three hundred kilograms.

Manufacturing a band sawmill requires special training and sufficient availability large quantity various building materials:

• pipes various sizes and diameter;
• metal corners for mounting the rail system;
• channel;
• pulleys;
• profile pipes for sleepers.

In addition, you will need tools for working with metal - a welding machine, an electric drill, a grinder and a set of fasteners (bolts, nuts, screws).

Work on the manufacture of the device begins with the installation of the stationary part - the frame. The shape of this design resembles the letter “P”; the material is two channels or angles 50X100 mm.

Standard length the channel is 8 - 9 meters, the height is at least 14 cm. After installing the frame, holes are drilled in it, the gaps between which must be at least one meter.

Afterwards, you need to tighten the channels with pipes 25 cm long, fastening is done using bolts of the required size and studs. After this, the racks on which the sawmill will be fixed are mounted. To increase stability, the structure is further strengthened the right amount braces

It is important to know: the proportions of all parts must match; for a sawmill 9 meters long, a saw measuring at least a meter is required.

A saw is attached to the trolley, and a steering wheel is installed on the side to control the operation of the unit. The clamps are made of pipes with a diameter of no more than 40 mm; movable hoses are installed inside. Clamps made of metal corners are installed on top of the pipes.

Lastly, the saw blade and motor are installed. It is best to construct the structure directly at the site of future work, since total weight band sawmill is very large.

Tire (logosol)

A homemade unit is fundamentally different from other types of sawmills in its design.

The main task is longitudinal sawing of logs, production of high-quality veneer and slats. Numerous videos on the Internet provide comprehensive information about all stages of installation of a tire sawmill.

This type of sawmill is used in small industries for the production of mini workpieces non-standard shape and size. IN homemade units a chainsaw blade of a suitable size is used as the working part.

The design consists of a profile whose working height is just over a meter. The chainsaw is moved using a trolley.

The exact height is calculated taking into account the height of the worker in order to avoid prolonged stay in an uncomfortable position. A log is placed on the main profile, the saw moves and cuts according to preset parameters.

The main condition necessary for high-quality operation of such devices is sufficient weight and rigidity of the main profile, as well as the presence required quantity supports To obtain an even cutting line, you must have at least four stable wheels and a manual drive.

It is optimal to use a well crank with a drive wheel. To adjust the thickness of the product, rigid fixation jacks are installed.

Independent production of any type of sawmill is labor-intensive and difficult process. Whether the waste of time and money is advisable is up to everyone to decide for themselves. In any case, when installing a unit of any type, one must not forget about safety precautions.

Injuries often occur while working with wood, and homemade equipment, assembled insufficiently well, poses a danger to the owner.

How to make a cheap sawmill with your own hands, see next video:

The band sawmill provides sawing of wood for its subsequent use for the purposes of repair, construction, production of various wooden products. Collected 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 on a band sawmill should know how this device functions, what spare parts are used, how to change these spare parts, etc. Without this, working 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 determined by the distance between the tension components cutting tool band press.

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 efficient processing 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.

1. 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.
2. 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, and whether all settings are set. Only after this can you cut the log and make the required cuts on your industrial or mini machine.
3. The logs are finished by hand. If the Kedr band sawmill can give a fairly accurate processing result, then the operation of 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 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. 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.

1. First, the rails are assembled. Approximate length - 8 meters. To avoid deforming them under the weight of the log, reinforce the structure with 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.
2. 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.
3. 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.
4. It is not recommended to place the pulleys parallel to each other. It is better to make a deviation of 4 degrees in 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.
5. 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.
6. The assembly is completed by installing clamps on the sawmill.
7. Leave the installation of the cutting saw and electric motor for last.

As you upgrade your DIY tape device it may have an electronic ruler, a more powerful engine, and all kinds 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.

The need for lumber in a private home will sooner or later lead to the decision to make a sawmill with your own hands at home. The need for inexpensive profile wood, high-quality building material especially relevant for private households. Attracted by the possibility of inexpensive wood processing, the production of profiles of various configurations, the possibility of use in basic structures, in capital housing construction, in repairs, use in external and internal finishing, construction of enclosing and auxiliary structures for various purposes.

Lumber of any profile and quality today can be purchased at any construction market or base, but any prudent owner planning to build a house or work that requires the use of a large number of wood products thinks about saving. If you make a sawmill, it will be possible to carry out work on your site or on the farm at a lower cost; excess material can be sold or paid for raw materials.

General description of the sawmill

Band sawmill or sawmill - universal machine for longitudinal sawing of logs to obtain various profile lumber: boards, timber, shingles, etc. The design of the sawmill includes four main parts:

• band-saw with drive;
• saw frame feeding device;
• cutting blade height adjustment mechanism;
• clamping and fastening device for logs.

The drive mechanism of the sawmill starts an electric motor, or it runs on gasoline (diesel).

Suitable for medium-power household sawmills asynchronous electric motor 5 kW or diesel (gasoline) with a power of 6-8 l/s. This will ensure uninterrupted operation of the installation in nominal mode without overloads.

The sawmill operates by transmitting torque to a pulley with a looped sawing band up to 6 cm wide. The slack of the band is compensated by a hydraulic or spring mechanism.

The installation frame with the drive mechanism moves along rails mounted on concrete foundation. Movement is provided by hardened steel rollers on sealed ball bearings, mounted at the bottom of the unit housing. The length of the rails determines the maximum longitudinal size of lumber processing.

A mechanism, including a threaded transmission and a drive element, regulates the height of the saw blade and sets the size of the cut. Two rotating screws on the sides of the carriage set its movement along the guides and prevent the saw from twisting.

The workpiece, prepared for dismantling, is placed between the guides and secured with hooks, which are wedged by blows with a sledgehammer. The carriage with the saw is brought to the end of the log and the height of the working blade is set. Then the machine is started and the frame with the saw is gradually moved along the rails, cutting off boards of a given thickness. Having reached the end of the log, the freshly cut board is removed. After this, the saw is raised and the mechanism is returned to its original state.

The clamp, made from a regular pipe guide on which bushings with hooks are installed, prevents the log from moving during feeding. The immobility of the log during processing is ensured by jamming of the mechanism and misalignment of the moving unit with fixed claws.

The given description characterizes the simplest band sawmill made with your own hands, using drawings. Scheme phased construction sawmills are described below.

How to make a band sawmill and what is required for it

Rail guides are made from a channel or beam with consistent geometry or factory rails from a narrow-gauge railway.

The rollers are turned into lathe and harden. It is better to use rolling bearings in rollers.

The frame, workpiece space and saw carriage are made from thick-walled rectangular and square section to ensure the necessary strength when loads change.

The mechanism that regulates the height of the working carriage is made of square metal profiles with sliders and two bolts and nuts. Parts are used from old lathes or turned into new ones.

Wheels, belt blades and shafts with rolling bearings can be taken from decommissioned combine harvesters or other agricultural machinery. The cross-sectional size of the guide should be about 500 mm to avoid mechanical stress on the structure and damage at the base of the teeth saw blade.

The cost of making a sawmill at home can amount to several tens of thousands of rubles. It is advisable to assemble a sawmill with drawings.

A homemade band sawmill is assembled with your own hands using the following tools:

• angle grinder;
• household welding machine;
• vertical drilling machine;
• drill;
• concrete drills;
• drill;
• metalwork clamps;
• socket and open-end wrenches;
• pliers;
• hardware and fasteners;
• laser level.

The optimal site for constructing a sawmill is 3x6 m, provided the length of the product is up to 6 m. It is advisable to place the installation indoors or then build a canopy using improvised means to be able to work in any weather. The main thing is that the site is built in good faith.

Recommendations for operating a homemade band sawmill

It is necessary to monitor the tension of the saw blade and do not operate the sawmill for more than 2 hours without a break. Change the working cloth regularly, hang it up to remove accumulated internal tension. It is necessary to use a lubricating fluid; in summer you can use a water composition with Ferry; in cold weather, mix kerosene with diesel fuel and engine oil in a ratio of 5:1.

After stopping the saw at the end of work, it is necessary to loosen the tensioners.

Regularly sharpen and trim saw teeth. It is not advisable to take freshly cut timber straight into work; let it sit for a month and trim the bark. It is necessary to regularly maintain the installation, periodically check the broaching and lubrication to maintain the operation of the sawmill.

The above assembly example can serve to assess the possibility of building your own sawmill using many available materials and parts. Subject to all technical parameters And correct installation and operation, the sawmill will function smoothly long time.

If you have a freer budget, it is better to use more details factory made.

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 disc 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:

1. Prepare logs, that is, adjust them to the same size and shape;
2. Sawing logs according to a given pattern after setting up the equipment;
3. 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.

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 does it work homemade sawmill, see 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. Position the corners better 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.

He assumes various variations devices, 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.

Are used in this case threaded rods or bolts.

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 inner 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:

1. The structure must be stable and strong, since you have to work with logs of different weights and sizes;
2. 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;
3. 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;
4. Homemade sawmills are “scattered” with shavings, so you need to either build additional designs, or do cleaning after work performed;
5. A wide band cut affects the generation of a large amount of waste;
6. 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;
7. 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;
8. All fastening elements must be securely fixed to ensure safe work the entire structure;
9. 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. Disc sawmill ready.
