DIY band saw from the hub
Mounting the boom and pulley supports
The most primitive do-it-yourself band saws with a frame made of plywood or logs have a support bar 8×8 cm thick. 2 strong supports are attached to it, which will hold the pulleys. It is advisable for band saws to create supports of strong materials, including plywood with a rigid core.
The distance between them is selected in such a way that the processed log can be placed there. Experts recommend making a small gap to prevent possible future problems.
Assembling the desktop
When creating a tape machine for divorcing wood with your own hands, you need to pay attention to its size. The comfortable height of the saw band is chosen depending on the characteristics of the building and the person. The main thing is that the lower and drive pulley, the power unit and a large amount of chips are normally placed in the free space. The form itself is chosen any, but most users stop at the option of a closed cabinet, which becomes a natural container for sawdust.
At the stage of assembling the desktop for the band saw with your own hands, it is necessary to provide a convenient way to open and place the pallet. this will allow you to conveniently clean the saw.
The table top is installed on the lower support. If its height is small, you will need to create a stand for the entire structure.
Cutting out pulleys and attaching them to supports
The band saw tension mechanism and pulleys are welded using special equipment. The diameter of the latter can be arbitrary, but the larger it is, the longer the saw can serve without breakdowns. However, it is important to keep an eye on the dimensions of the blades, choosing a ratio of 1/1000 in relation to the pulley diameters. A piece 40 cm long should have a diameter of 4 mm. But if you follow the rules of use, even a narrow pulley for 6 mm canvases can be used.
When compiling the parameters of the diameter, it is necessary to take into account the following principles:
- First you need to calculate the pulley circumference using the following algorithm: D = 3.14 pulley diameter.
- The average speed of the cutting blade should not exceed 30 m / s.
- At the next stage, it is necessary to determine the number of revolutions. it is 0 = 30 m / s.
- Next, you need to calculate the ratio of motor revolutions in relation to the rotations of the drive pulley.
- The set of teeth is selected individually depending on the purpose and scope of the saw.
So that the band saw itself is located in the center and does not fall off, the edge is made convex, adhering to an angle of 5-10 °.
It is recommended to leave a small groove on the belt drive pulley where the belt will be located. The pulley itself is covered with rubber from a bicycle or car wheels.
The selected diameter should be 1-2 sizes smaller than the pulley diameter, which will exclude the possibility of blade slipping. The top piece is fixed to the movable block and moves in a horizontal position to ensure that the cutting edge is tensioned normally. For this, a band saw tension mechanism is used, which can be used as a bar under the block to which a spring is attached. When the technician presses the lever, the structure automatically raises the pulley block, pulling the saw.
Even at this stage of assembly with your own hands, you need to take care of the method of fixing the lever in the selected position. It is better to solve a similar problem with bolts that are at different levels. The spring will provide the optimum pressure to absorb the stress.
The lower block contains 2 pulleys: driven and driven. The main thing is to make sure that they are sufficiently balanced, and the likelihood of “eights” appearing during the rotation is excluded.
To secure the upper pulley with your own hands, it is better to use a self-aligning bearing. It allows for quick removal and reassembly of wheels. In this case, the wheels themselves must be fixed with maximum strength, otherwise the bearings will begin to loosen.
Assembling the frame
When assembling the band saw frame, it is better to give preference to hard and sturdy wood species. Otherwise, the final structure will not have the required rigidity and will begin to create vibrations. Individual elements, including the work table, are made of durable plywood, and the stiffeners are additionally reinforced with slats. The most affordable option is to dismantle old furniture.
Sega a nastro portatile fai da te (homemade portable bandsaw)
The first step at home is to draw up drawings, on the basis of which the frame will be assembled. They are created taking into account the height of the working room and the physiological characteristics of the person who will work behind the saw.
Installation of blade guides
The next step is to fix the saw band guides at a 90 degree angle. This will prevent uneven and irregular workpieces with crooked ends or defects.
The simplest solution is to screw 3 bearings to the bar: 1 fixes the flat side, and the rest are designed to fasten the tape on the sides.
An important stage in the installation work of a band saw with your own hands is the alignment of the guides in relation to the fixing point of the support. Otherwise, even small deviations will lead to large defects and deformations.
Alternatively, wood stops can be used for 2 bearings. You should also fix a row of guides under the table. It is important to fasten them in such a way that they are placed closer to the workpiece, and even better. at a distance of 3-4 cm from the log.
If you want to work with materials of different thickness, it is recommended to provide for the possibility of adjusting the height of the guides.
DIY band saw assembly instructions at home, training videos
When developing a homemade band saw, it is important to understand how it works and for what purposes it will be used. In the case of running a private business, you can create a band saw with your own hands, capable of working not only with wood, but also with other materials, including:
- A rock.
Due to the high density, such materials need to be processed with special machines made of reinforced steel. Standard metal is not capable of properly cutting stone or metal workpieces. Also, he cannot handle hard wood.
Final finishing, checking and setting
A saw made of wood can be used immediately after assembly, however, experts recommend that you first equip it with a casing that will cover the upper pulley.
Such manipulations will not only give the design an aesthetic appeal, but also increase the degree of safety: even if the belt slides off the pulley, it will stop in the casing. Provide a chip container as an optional accessory that can be easily accessed.
It is recommended to remove the belt drive from under the work table, protecting it from sawdust. The power unit is protected by a casing isolated from dust and other debris.
The final stage of wood processing with varnish or paint has a positive effect on the service life of the tool, and also prevents injury from contact with chips and chips of untreated material. Before use, all surfaces are additionally sanded and impregnated with antiseptics. they prevent rotting and the development of mold.

Homemade band saw, made by hand: a detailed description of making homemade products with photos and videos.
Hello everyone! I needed a band saw for a home workshop, I decided to do it myself.
There was a 300 watt electric motor available, I decided to use it for my homemade product.
The tape will also be used. 1830 x 16 mm. We will make the drive wheels from plywood.
These are the blanks for drive wheels.
I welded a frame from a corner, installed an engine, drive wheels, made a belt drive.
To prevent the saw from sliding off when cutting, I installed thrust bearings. The unit consists of three bearings and two angles.
The holes were oval to adjust the gaps between them and the tape. There are two such knots, the second is placed under the table.
Retractable rod, consists of two welded corners and an inserted profile tube. Fixed with a bolt through a welded nut. The boom body is bolted to the horizontal angle and has mobility for adjustment.
I made a table frame from a profile pipe, a chipboard sheet will be screwed onto the frame.
Installed tape protection on the side opposite to the cut, and a box on the upper wheel.
The result is a homemade band saw for a home workshop. Saws very well and quickly, I am completely satisfied with the homemade product.
I also recommend watching a video showing the band saw in operation.
DIY band saw
Friends, Hi. I want to introduce you to a homemade product that I made about a year ago. This is a band saw for wood. Its design is not very complicated, and with the proper skills, almost every master with a small set of tools can repeat it.
From the tool you need: Welding, grinder, jigsaw, drill, crowns, hand tools.
The band saw is a metal frame on which two wheels are mounted. A saw band is put on these wheels. One of these wheels is driven by an electric motor. Let’s start with the wheels. I decided to make the wheels from plywood. Since there was no plywood of the required thickness, I had to make them from two halves with a thickness of 16 mm. I had a saw blade of 1920 mm. So that the canvas does not wrinkle much, the diameter of the wheels chose 200mm. To make two wheels, you need to cut 4 blanks. In my case, the thickness of one was 16 mm. The lower wheel must be driven by the motor, so I cut two more pieces of smaller diameter. It turns out that the upper wheel consists of two parts, and the lower one of four.
Next, we need side covers from the engines of old washing machines. They will serve as bearing housings. Cut off all unnecessary as shown in the photo. In the discs, we make central holes with a 40-bit crown. Next, we fold our package, install the covers on the sides and drill 4 holes with a drill. I wanted to glue all the plywood discs at first, but then I thought that it would be superfluous and a tie for 4 M8 studs would give good rigidity. The same procedure must be repeated with the top wheel. In principle, the wheels are ready, but there is one caveat. They are terribly crooked and hit very hard. I thought for a long time how to align them and came to such a decision. The covers have a threaded hole, like the M4. Having rummaged in stocks, I found on a pulley from an old washing machine.
A rectangle-shaped base was welded from a 50 × 50 corner. On one of the short sides, a stand was welded perpendicularly, consisting of a 40 × 40 profile pipe and reinforced with a 50 angle.
I sawed everything in place, so I will not say the exact dimensions. On the frame in the middle, I welded a cross member, to it a small stand and an upper cross member, to which the wheel axle will be attached. I think everything will be clear in the picture. If something goes wrong, below the text there will be links to the video, there you can examine everything in detail. I decided to weld the axle to the upper cross member stupidly. By the way, he turned the axles on his TV-16. I also forgot to say that a spacer sleeve made of a water pipe was installed between the covers. Adjusted the diameter of the axle to the inner diameter of the bearings and cut a thread from one edge.
The wheel is put on the axle and abuts against the protrusion, on the other hand, it is tightened with a nut through a washer and counter-tightened. The axle was first grabbed by welding, then the wheel section, a level was applied to it and aligned with the frame and the vertical rack. Then the axle was finally welded. On one side of the frame, I temporarily installed the motor and put on a belt. By the way, the motor from the washing machine is an automatic machine with a capacity of about 400 watts. The channel has a video on making an Arduino-based controller for controlling such motors. This controller allows rpm control with power support. Also in the near future I will post here an article with a detailed description of how to assemble such a controller. Wait a bit. I plugged the whole thing into an outlet and slowly added speed. Everything is spinning, nothing is shaking, the bearings are not heated.
Now let’s start installing the top wheel. It’s a little more complicated here. This wheel should move in two planes. Up and down to tighten the tape and release the tension to replace it. Also, the wheel should tilt. This is necessary to adjust the tape so that it runs strictly in the center of the wheel. The solution to this problem looked like this.
I took two pieces of tubes about 30 cm long. I welded nuts on the ends. I drilled holes in two pieces of 50 corner at an equal distance and bolted the tubes. It turned out to be something like parallel guides. Now we cook something similar to a profile pipe from two corners, having previously inserted a tube there. Moving elements turned out. We connect them with a jumper. Now we cut 4 pieces from the same pipe. We weld two of them along the edges, at the bottom of the movable frame, this is important, and the remaining two are welded inside the corner.
We pass a suitable axis through the tubes. The axle of the upper wheel will be digested to this movable corner. We also fasten the top of the movable frame with a corner. A hole will be drilled here and an extension nut will be welded. A long hairpin will be screwed into it, which will pass through the upper corner. There will be washers and two lock nuts on the top and bottom of the corner. A handle is screwed onto the hairpin. This will move the tension carriage. On the reverse side of the carriage, a jumper is also welded at the bottom, a hole is drilled and a bolt is screwed in. It rests against the corner with the axle and allows you to adjust the inclination of the upper wheel. How hard it is to write it so that it is clear. When everything is ready, this structure can be welded to the rack. I did this. The upper and lower corners, on which the tubes are held, were initially taken longer, since I had no idea how it would all fit together. I applied a level to the ends of the wheels and set the wheels strictly vertically relative to the rack. That is, the saw blade should move parallel to the bar. Then I marked the upper and lower corners and cut off.
Now I applied a level to the ends of the wheels and fixed it with clamps. I used a level on one side of the wheel and a flat rail on the other. So we will achieve the position of the wheels in the same plane. With everything in place, you can weld the top wheel frame to the B-pillar. After welding, you can put on a saw band and try to turn it on. It is better to stand behind the machine, so as not to be injured. Before starting the wheel, be sure to turn it manually. The tape will fall off at first, but you will figure out how to adjust it correctly. And only after it runs stably in the middle of the wheel, you can turn on the engine. If all is well, we continue further. If the tape still tries to fly off the wheels, then somewhere it was wrongly welded or not adjusted.
After assembly and testing, the machine was painted. The power of the motor is sufficient for everyday tasks. very often I use it to cut slats from scraps from a large sawmill.
It is very difficult to describe all this in words. Better to see once. I will attach a video. There you can consider everything in more detail. Until next time. Until!
DIY band sawmill
Homemade band sawmill, made by hand at home, photo and detailed description of the saw design.
I decided to make a homemade wood sawing machine. I bought square pipes 20 x 40 mm, and 20 x 20 mm (for reinforcement) wall 1.5. Then I sawed and welded just such a structure.
Engine 2.2 kW at 1500 rpm.
I cut circles out of steel to make wheels for the canvas. The saw band was used by PL-600 (the length of the saw blade is 1638 mm, the width of the saw is 12.7 mm, the thickness of the saw blade is 0.65 mm).
I did not do the guides for the tape in principle, since the discs should guide the web well enough.
Diy Metal Band Saw Using Bicycle Wheels
I didn’t make a support bearing, because I thought that there should be enough beads on the wheel so that the tape would not run away. And there were no particular thoughts on how to attach it to the wheel and frame (after all, one wheel is movable and therefore the bearing must also be moved.). Although it is probably possible to make one support bearing at a stationary wheel. If the tape is set so that it moves with the sawing part on the stationary wheel, then this bearing will not let it fly off and on the movable wheel it will be set automatically as it comes to it from the stationary already exposed. But this we need to think it over.
Now about how I made the wheels themselves.
First I took a steel circle and cut a pancake off of it.
On a lathe, I pierced a hole for the shaft (on the second wheel for the bearing) and pierced the outer surface by creating steps (they are coaxial with the central hole).
I cut squares out of steel sheet. He clamped the faceplate into the lathe chuck and glued the plate with double-sided tape with a rotating center and cut out a “donut” with a central hole slightly less than the diameter of the central part.
With the central hole, the resulting discs sit tightly on the “step” of the central part of the disc and automatically we obtain parallelism and coaxiality of the lateral parts. Then I grabbed them by welding.
At the end, I took an iron strip and welded it along the outer part, slowly bending it right in my hands (I weld one end, then I pull on the other and the strip itself falls on the side discs) and grabbed it by welding along the way.
Well, the last thing I did was install the finished disc on a turner and grind the outer part of the strip, forming a collar for the tape and removing all the flaws and curvature of bending. Of course, for good, you need to balance, scald better and paint after stripping. But first I’ll leave it like this.
Then he welded all this for a long time and stubbornly, bought bearings, drilled and twisted. As a result, we got such a band sawmill with our own hands.
Further pictures of some nodes.
Saw blade tension.
Launched it through a chastotnik. It’s scary, of course, without a casing. At first the canvas jumped off, but the tension screws managed to set such an angle that it sat evenly.
Dismissed a dry tree.
The boards turned out to be quite good in terms of the consistency of dimensions, even despite the curved fastening of the log with 4 self-tapping screws on the stake driven into the ground.
The quality of the cut (surface cleanliness) was also very pleasing.
I think we need to increase the number of drive belts, as sometimes it slips with one (well, or just tighten it for a start).
Now I’m thinking about how best to organize the securing of the log and its rise to the desired height.
While I plan to lift with a screw jack and fix it by screwing it to the end of the horizontal plate and fix it to the base on which the jack or something similar will stand.
Well, protection must be done. Most likely from something like a fine welded mesh (so that you can see what is happening under the casing).
We recommend that you look at another homemade product. a tire sawmill.
Purpose and principle of operation
The sawmill is used to obtain various lumber (bars, slats, boards, sleepers) from solid logs. It is used in woodworking factories, sawmills, furniture factories and in the construction industry. This device allows you to:
- Reduce the amount of chips and other dirt that appears during wood processing.
- Saw short workpieces with a length of 1 m and receive parts with a thickness of up to 0.2 cm.
- Reduce energy costs.
- Set the dimension of the received sawn timber.
- Produce wood parts with high surface quality with an accuracy of 2 mm.
The sawmill has the following advantages:
- Mobility. The woodworking machine can be quickly disassembled and moved to a new location.
- Stability of the structure. The woodworking machine can function under harsh climatic conditions both indoors and outdoors.
- Ease of use. The sawmill is equipped with many automatic mechanisms to facilitate the processing of logs. During operation, it does not make unnecessary noise.
The disadvantage of this unit is its high cost. It depends on the type of machine and its technical characteristics. The brand of the manufacturer also affects the cost of equipment. The most expensive devices are from Swedish and Canadian manufacturers. Their average cost is 324 thousand rubles. Machine tools manufactured in Russia cost 135-220 thousand rubles.
- Stanina. It has a U-shape and is assembled from 2 parallel channels. A mobile trolley with a horizontal saw unit moves along the bed. Frames and brushes are also fixed on it, designed to clean the working surface from sawdust and other industrial debris.
- Saw frame. This part is a device consisting of several welds. Driving and driven pulleys are located at its ends. The movement of the saw frame is carried out using metal rollers and an electromechanical drive with driven and driving wheels.
- Guides. They are fixed in the middle of the saw frame with brackets. Support rollers and stands for logs are located on the guides.
- Screw mechanism. It is necessary to adjust the thickness of the workpieces being processed. This element allows you to prevent skewing of the log during processing.
- Clamping device. It is designed to fix the log when sawing. The clamping device consists of a round tube and bushing clamps.
- Saw. It acts as the main cutting element of the sawmill. Its average width is 6 cm. The saw is tensioned using a hydraulic or spring mechanism. It allows the operator to adjust the position of the driven pulley and prevents the cutting element from coming off the wheels.
- Coolant tank. It is used to prevent sawdust from sticking to cutting elements. The tank has taps for fluid supply.
- Electric motor. It is designed to transmit torque to the pulleys and activate the chain drive mechanisms that move the saw frame. The average power of the electric motor is 5 kW.
- Remote Control. It is located on the top lintel of the woodworking machine. Next to the control panel, on the operator’s side, there are measuring instruments for accurate calculation of the thickness of the resulting sawn timber.
The device for home sawmills is organized in the form of several blocks. This design is easy to manufacture. Its disadvantage is its low performance. Therefore, these machines can only be used in domestic conditions to obtain a small amount of sawn timber. The principle of operation of this unit consists in cutting a log fixed on a special platform with a saw tool located in a horizontal position. The dimensions of the received sawn timber are preset by the operator.
The main types of sawmills
There are the following types of sawmills:
- Framed. It is a structure with flat saw blades fixed to the frame. The frame sawmill is most often installed in large woodworking shops. This device is distinguished by its high power, structural strength. The frame sawmill does not require additional maintenance. Its disadvantage is the large thickness of the cut, which increases the amount of chips generated.
- Tape. The workpieces are processed using a saw band controlled by stabilizing rollers. The cutting element performs only translational movements received from the rollers. Band sawmills are used in small woodworking shops.
- Disk. It is one of the most common types of hand-held sawmills. It is equipped with a toothed disc. Each tooth cuts a small section of the log. To improve productivity, these machines are equipped with multiple cutting discs.
- Chain. Sawing of logs is carried out using a chain saw mounted on a frame with a metal profile. The chain sawmill is lightweight and small in size. Therefore, this mini machine is most often used in the domestic environment.
When choosing a sawmill, it is necessary to determine the volume of workpieces to be processed and the operating conditions of the equipment. You also need to take into account the technical characteristics and materials from which the cutting elements are made. One of the main selection criteria is the structural strength. The woodworking machine must be able to support the weight of the logs being processed.
Sawmill is a woodworking machine used for longitudinal sawing of workpieces from various types of wood. It was invented in the Bronze Age and was originally used in shipbuilding. To design a sawmill with your own hands, you need to know the device, the principle of operation and the main varieties of this unit.
The assembly of a band-type woodworking machine requires special wheels and band saws. Initially, the machine frame is assembled. Then the rail guides and sleepers are made. Devices for fixing the workpieces to be processed are attached to the profile pipe. According to the drawings, the mobile trolley is assembled and installed in its lower part of the wheel. At the end, an electric motor is connected to the working mechanism.
How to make a sawmill with your own hands
Before you make a sawmill, you need to choose a place where the future machine will be located. The minimum area of the working room should be 18 m 2. The equipment can be placed in an open space. In this case, it is recommended to build a fence around the self-made sawmill and install a small canopy over it. This will allow you to process workpieces in all weather conditions. It is also necessary to pre-equip the storage place. It is recommended to store the sawmill in closed rooms with low humidity.
In order to make a sawmill, you need to purchase the following tools and accessories:
- Cutting elements: chains, saws, discs and frames. To make a band sawmill, you need to purchase several saw blades.
- Measuring instruments: ruler, tape measure, level, vernier caliper.
- Coolant tank.
- Fasteners: Angles 100 × 100, 8 M16 bolts, nuts, screws and washers.
- Pipes 80 × 40 and 60 × 60 Also requires a round pipe with a diameter of 50 mm.
- Electric motor and bearings.
- Rollers, tracks and multiple hubs.
- Hammer, drill, pliers, grinder.
After the selection of accessories and tools, it is necessary to develop the drawings of the sawmill. They should be marked:
- Dimensions of the site where the equipment will be located.
- Distance between sawmill rails and transverse installations.
- Location of rollers, screws, bearings.
- Total number of corners and metal pipes.
The assembly process of a woodworking machine is carried out in several stages:
- Foundation construction. Its height should not be 10-15 cm.It is necessary to install a reinforcing belt and a pillow of sand and gravel on the base.
- Installation of guides from corners, rails and channel bars. They must be laid with their edge up. With the help of anchor bolts, the guides are attached to the base of the machine. Sleepers are laid between the rails. The corners are fixed with a threaded connection.
- Arrangement of a platform for fixing logs. H-shaped parts of the profile and protrusions are attached to the sleepers.
- Assembly of rollers from bearings. They must have the same inner diameter. The difference between the outer diameters of the parts depends on the height of the rail and the angle.
- Assembling the saw frame. Bushings are installed on 2 metal pipe guides installed in a vertical position. The frame for the mobile cart must be rectangular. In its lower part, rollers are installed.
- Installation of the screw mechanism. The nuts are attached to the lower sliders, the stops are attached to the upper bar. Tension adjustment devices are installed on the shafts of the screw mechanism, fixed between the rollers and brackets.
- Securing wheels and hubs to the bottom of the frame. These components are attached using bearing assemblies. A pulley is mounted on the hubs that receives torque from an electric motor.
- Installation of the power unit on a vertical frame. It is connected to the screw mechanism using a pulley. To increase productivity, it is recommended to equip a homemade machine with a motor from a walk-behind tractor. It runs on gasoline, which increases the power of the unit. Sawmills with an engine from a walk-behind tractor are distinguished by high noise.
After installing the electric motor, it is necessary to connect the machine to the mains. It is recommended to equip the unit with a steel shield that protects the operator from sawdust and industrial debris. During the operation of a homemade saw, you need to periodically sharpen the cutting elements.
A chain saw is required to make this woodworking machine. It is installed on a level surface, which allows the operator to control the machine from different sides. Initially, the frame is made of a profile made of steel. Several holes are made at the base, on which the bed is fixed. On the base, a stop and clamping mechanisms are installed, required for fixing the electric motor. At the end, a saw with a chain is fixed.
Angle or circular sawmill
For sawing many logs, you need to use angle or circular sawmills. They are distinguished by their high power and structural strength. You can make these sawmills with your own hands from an electric saw. Guides are installed on the frame. The joints are held together by welding. In the absence of an electric saw, you can assemble corner or circular sawmills from a grinder. It is recommended to use a gasoline engine as the main power unit. It will increase the power of the device to 6-9 liters. from. The disadvantage of a gasoline unit is the noise of operation.
How to make a sawmill with your own hands
The most common types of sawmills are angle, belt and chain saws, as well as devices assembled using a chainsaw.
It is rather difficult to assemble a band-type sawmill with your own hands at home. This is explained by the fact that it is difficult to achieve the maximum coherence of all its constituent elements in the process of work. In addition, the necessary components and special tools will be required, but, most importantly, the necessary drawings are at hand. The finished structure should work with material weighing about three hundred kilograms. In addition, it is necessary to debug the adjustment of the rifling thickness and observe safety precautions.
Do-it-yourself sawmill assembly is carried out on a site of the required size, which should be prepared in advance. The device will need special wheels and band saws. Then, in accordance with the drawings, the frame of the future unit is assembled. The work on the frame begins with the manufacture of special rails. To do this, you can pick up a corner and set one of the sides up. Then the wheels are installed, observing the ultimate strength.
Between the two corners, set in parallel, sleepers are made from a profile pipe, which are designed to ensure their reliable fastening to each other. A fastener for logs is welded to this profile pipe, which can move freely in all directions. Then, according to the drawing, the cart is assembled and the wheels are attached to it.
At the end, the installation of an electric motor is carried out, connected through a special pulley with the working mechanism of the device.
Angle or circular sawmill
If there is a need for a radical sawing of boards, then it is best to use an angular or disc structure for this.
The angle sawmill has many functions and is used for large volumes of work. It is best to make such a structure with your own hands, because the finished equipment is very expensive. To assemble it, you should use the appropriate drawings, and before starting work, you need to purchase all the necessary components and components.
First, the frame is assembled from metal pipes and high strength guides. All joints are welded together. It is best to use rails as guides. Then the carriage is assembled. During assembly, special attention should be paid to the accuracy of all dimensions that are indicated in the drawing.
A high-power gasoline engine is installed in an angle or circular sawmill, which effectively affects the process of sawing wood. The engine is mounted on the structure frame and connected to the working elements through special holes. Most often, a chain transmission is installed on such sawmills, but in some cases this leads to overheating of the drive itself. During assembly of the actuator, due attention must be paid to safety measures and to exclude possible risks during its operation.
Sawmill from a chainsaw
In a domestic environment, such a large sawmill is most often not required, so a mini-machine, which can also be made by hand, will be considered the best solution in this case. There are several types of mini sawmills, they are small in size and, if necessary, can be easily moved to another place. Such a device is made using a chainsaw, which acts as the main element.
To make a mini-sawmill from a chainsaw with your own hands, you will need:
- two channels;
The work begins with the assembly of the frame, on which it is necessary to drill several technological holes. Then screeds from a metal pipe are installed. They are fastened with fixing bolts in pre-drilled holes. During installation, it is imperative to control the angles between the elements: they must be straight.
To strengthen the frame, several stiffeners are mounted. Then, the movable cart is assembled from the steel plate. At the bottom of this plate, two corners are welded, after which it is placed on bearings or rollers. Two corners are welded to the top of the movable trolley, designed for fastening the chainsaw.
In conclusion, a special structure is installed for fastening the processed logs.

Making a sawmill at home with your own hands
When it is necessary to process a large number of boards and wood, it is best to use a DIY sawmill. Many people believe that it is best to purchase a ready-made unit, but it will not be difficult to make it yourself. The main thing is to decide on what the volume of the upcoming work will be, as well as on the wood, after which it is necessary to choose the type of sawmill to successfully complete the task.
When assembling the unit with your own hands, special attention should be paid to safety issues, because such a device is considered an object of increased risk. The manufacture of various types of sawmills is presented below in the video.
The principle of the sawmill
You can explain how the sawmill works using the example of spools of thread. Such a device resembles the rotation of two coils with a thread stretched between them. It is she who acts as a saw, and the distance between the coils will be the optimal size of the log.
The do-it-yourself sawmill allows you to:
- adjust logs to the same shape and size;
- sawing logs according to a specific scheme after the equipment is configured;
- after sawing, small defects often form, which cannot be eliminated, so the tree has to be processed manually.
The work of the sawmill is carried out as follows: a log is fixed on the platform, which remains motionless, and at this time the mobile cart starts to move and cuts the tree. The saw must be in a horizontal position.
In order to get the boards of the required size as a result, the operator initially sets the required parameters. The saw band acts as a saw and must be well tensioned.
The principle of operation of such a homemade product resembles a band sawmill, with the only difference that it uses a chain saw. The design of such a device is much simpler and smaller, which means that it is much easier to make it yourself. The chain sawmill is installed on a level platform in such a way that it is convenient to approach it from any side.
The assembly of the chain device begins with the fact that the frame is made from a metal profile.
