When working at home, you always need to know how to make a tool with my own hands. A homemade circular saw will perform its duties no worse than its factory counterpart, and its maintenance and dismantling will be much easier. In special cases circular saw can be converted into a radial or angle grinder, which has its own very pleasant moments.

You can make a circular saw yourself, for this you need to have good drawings and tools.

Working with a saw and grinder

Tools and materials:

grinder 150-180 mm;
drill;
self-tapping screws;
steel clamps;
sheet steel;
pliers.

Before you make a circular saw yourself, you need to try making it from other tools. Most often, the process is organized using an angle grinder, because it can be remade much faster and easier than any other analogues.

The simplest option best damages the instrument. To do this, you will need to screw the tool to the base using metal screws. If desired, you can do it with a drill through holes and tighten with bolts and nuts, which will be much more reliable in operation, because the tool will no longer strip the thread in case of strong tension. The only nuance that should be taken into account is the factory imbalance of the tool, due to which you will have to fix it very carefully so that there is not even a small chance of movement.

If desired, you can complicate this design, and this will also protect the instrument from unnecessary interventions inside. For fastening, you will need steel clamps that wrap around the tool at 3-4 points and then secure it with bolts on both sides. This design is very reliable, but special attention should be paid to the quality of fixation in order to avoid even small misunderstandings.

For those cases where the tool is made stationary, you can use more powerful options for angle grinders. The angle grinder itself is attached to the reduction gearbox using bolts or self-tapping screws (depending on the ability to make a joint without damaging the tool, because sometimes the mounting locations do not match), after which they are installed together on the table top and screwed in the highest quality way.

Most reliable way will at the same time be the most difficult, because the support of a turner-miller will be required. His task is only to carve a special part that would be suitable in its parameters for coupling the grinder and the tabletop. This method The coupling is the most reliable, and even microscopic movements are eliminated, which is not possible to achieve in every factory tool.

It is necessary to take into account the fact that in any case it is deleted protective cover, and instead a homemade one is made from sheet steel. It will no longer be possible to use the mount for the casing due to the fact that it is used for coupling, and the homemade product should be mounted directly to the tabletop. To make it, you need to cut a semicircle from sheet steel, the end of which is bent and clamped with pliers. This design will withstand any surprises after it can be screwed on.

When choosing an angle grinder, you need to be extremely careful so that the number of revolutions is small and the power is high. If the speed exceeds 4500 rpm, you will have to use reduction gears, because otherwise, the cutters will grind down very quickly.

It is very important to remember that under no circumstances should a circular saw made from an angle grinder be remade back, because For this reason, every day in all parts of the world people are admitted to hospitals with injuries of varying degrees of severity. Even if the grinder is urgently needed, and there is no other option, it is better to be patient, because even the factory protection will most likely not save you.

Saw conversion

Tools and materials:

Diagram of a carriage for a circular saw.

chain Saw;
flat steel roller;
nozzle for cutters;
reduction gear;
welding machine.

Electric saws and chainsaws are a gift from the 20th century, which fits very harmoniously into life, but there are situations when it is desirable to remake them, which is not easy. Please note in advance that this alteration is of a momentary nature, but if desired, you can repeat it over and over again without any damage (the replacement will take some time).

In order to get a circular saw, you only need to weld a movable wheel at the very end of the boom and cut off the end itself. The wheel must perfectly follow the contour of the cut element so that the chain does not stretch or fall off when moving.

An adapter for cutters is attached to the side of the wheel. This adapter is removable so that there are no difficulties when sawing with a chain.

With high-quality modification, the wheel will not in any way harm the performance of the chainsaw in the absence of cutters at this moment. In addition, the basic operating speed allows you to do without serious third-party modifications.

Using an electric motor

Tools and materials:

asynchronous motor;
sheet steel;
wires;
reduction gear;
bolts with nuts;
adapter for cutters;
pliers.

There are many electric motors, the most popular being commutator, synchronous and asynchronous motors. For this activity, the asynchronous option is suitable, because it has the highest power levels, low revs and a huge reserve of endurance.

It will be very simple to make a circular from it, so everything can be done in stages:

An engine of 4000-4500 rpm is selected, with a power of 2-3 kW and powered from a 220 V outlet. If an engine with such parameters was not found, then you will have to use a gearbox that will bring the number of revolutions to the required one. The connection is made using bolts and nuts, but it is advisable not to resort to self-tapping screws, as they can cause significant damage.
Now you need to choose which attachment you will use: chains or cutters. The cutters grind down quickly, but produce a thinner cut, which makes it possible to achieve greater accuracy. Chains grind much more slowly, but during operation they contain several times more sawdust. Most often, preference is given to cutters, because the base price of wood with them is slightly cheaper, and the quality of the cut is higher.
An adapter for cutters is attached to the motor shaft. If a gearbox was used, then it must be mounted on the gearbox. In this case, the joint is made without welding, so that if necessary, you can replace the nozzle with any suitable one.

At the very end, a protective casing is made from sheet steel using the method described above. The casing is attached to the gearbox or motor so that there are no complications.

Your own sawmill is a profitable device, since wood is one of the most popular building materials. There are two options for getting a sawmill: make it yourself or buy it in a store. Of course, the second option is simpler, but the first has more advantages. First of all, a homemade electric chain saw is more cheap product, in addition, such a device will fully meet the owner’s requirements.

Below are two options for homemade saws: tire sawmill from an electric saw and a circular saw from a hand-held circular saw. To make the first one, you will have to make some purchases, as well as stock up on a welding machine; the second option can be made from materials that any owner will probably have in his garage or on his property.

The sawmills that are sold in the store are excellent productive devices with great functionality, designed for large volumes of wood. Such a tool can pay for itself in 2-3 months, but it is not advisable if used exclusively for domestic purposes. In this case, you can make it yourself using a small electric saw.

Currently, three types of sawmills can be found on the tool market:

disk;

tape;

tire

Circular saws are one of the most common saws on the farm. Their disadvantage is the high cost of high-quality discs, as well as the relatively large amount of waste. Band saws are the most economical, they are not afraid of bad weather, leave little waste, but at the same time they have a complex structure, which makes making them at home a very difficult task. The simplest version of a sawmill made from an electric saw is a busbar; they are distinguished by their elementary design and can also process large volumes of wood of any thickness.

Making your own splint saw

In order to make a sawmill yourself, you will need drawings and certain calculations. The manufacturing process is not particularly complicated; the only point is the availability of all the necessary resources. Naturally, a homemade sawmill will be inferior in performance to factory-made products. However for the production of beams and boards will fit perfectly.

To make a chain saw you will need certain materials:

metal rails;
metal tubes with different diameters;
electric motor;
chainsaw tire;
drive sprocket (also suitable for a chainsaw).

As an electric motor, you can use any engine, for example, from a semi-professional electric saw, from an old chipper, or you can purchase it specially.

If the choice falls on the purchased option, then a three-phase electric motor with a power of 5.5 kW is ideal for household needs.

Assembly of the cutting part

The cutting part is represented by a tire and an electric motor connected to each other. The entire structure is placed in a metal frame, which is mounted on a vertical strong axis. In other words, the frame in which the saw is enclosed will be able to move vertically within another frame. This movement will occur due to the guide axis.

The first stage will be frame manufacturing, in which the tire will be installed. The frame has the shape of a rectangle. On one side of the tire it is attached to a vertical axis, which ensures rotation.

The sprocket that allows the tire to move has a central hole. An axle made of a strong alloy, which has high strength, must be inserted into it. Perfect fit low carbon steel. The axle resists the horizontal movement of the tire, that is, the tire itself has a horizontal position in space, and the axle is vertical. Bearings are placed on both sides of the axle close to the tire - this helps to avoid vertical displacement of the cutting part. After this, bushings are put on top, which clamp the bearings.

The upper part of the axle is attached to metal profile. The opposite part of the profile is welded to the frame in which the electric motor is installed. Thus, a rectangle is formed in the following way: Bottom part– a tire, an axle and an electric motor on both sides of it, top part- plank.

This design does not allow the tire to play during operation.

The electric motor and drive drum are attached in the opposite part from the axis. To attach them to the bar you will need the remaining parts from the electric saw. The electric motor is installed on a rigid housing. Here we must take into account large vibrations, which means that the base for the engine must be very rigid. A metal axle or rigid profile is welded on the engine side. It is due to this that the entire cutting structure will move vertically to ensure that the log is cut in the right place.

Transferring the body with the saw to the base

The next step is to transfer the entire structure to the main frame, which has the shape of a parallelepiped. This frame mounted on casters, which will move along the rails and cut the log. The sides are a welded frame made of thick metal. They are fastened together at the top. In other words, the front view will resemble the letter P mounted on rails.

The distance between the side posts is 1-1.5 meters and is calculated based on the length of the tire: it should be slightly larger. The side posts themselves are so wide that a structure with a cutting base can be installed inside. If this structure is 60 cm wide, then the width of the side edges should be the same. This is done with the expectation that a saw will be installed inside one of the racks. The axis along which it moves is attached at the top and bottom inside the side frame.

Thus, vertical movement is ensured by the axis. Horizontal movement occurs using rollers that roll on rails.

Making a circular saw from a hand-held circular saw

For a home craftsman, having a circular saw at home is a matter of vital importance. It’s quite possible to do it yourself. The easiest way to make a circular saw is to use a hand circular saw. To manufacture a machine, the design of an existing saw does not need to be altered. Enough make a table for her. Obviously, the saw will be fixed under the tabletop, and the disk will be located above it through a special hole.

To make a table you will need wooden blocks 40*40 and plywood. A square base is made with a side length of 80 cm and a height of 40 cm.

A square sheet of plywood is used as a tabletop; it is best to use varnished or laminated plywood - it ensures smoothness and easy sliding. A cut for the disk is made in the central part. Holes are pre-drilled in the corners for attaching the table top to the table.

A disk disk is attached to the bottom of the tabletop. hand saw. The easiest way to do this is with bolts. The hats must be carefully sunk into the surface.

To turn on the saw, you need to fix the power button on it, and insert the power plug into the socket that will be connected to the start button.

For ease of use, you can attach a metal corner to one side, which will serve as longitudinal stop. To move it, you can make cuts at right angles to the disk, and move it by loosening and tightening the bolts that secure this stop.

A circular saw made from an electric saw is a simple and inexpensive option For home use. Of course, when installing the tool, the thickness of the table top will steal a little from the disk, but in general, this option is quite enough for household needs.

Today, it is almost impossible to buy a stationary sawmill for your home, as it costs incredible amounts of money. However, when you need to cut wood or process it, there is only one option left - a DIY chainsaw sawmill. Certainly, homemade instrument It’s still a long way from the factory equivalent, but for a home this design will be enough. Not many people know how to make it at home, so it’s time to delve deeper into this issue.

What is a chainsaw sawmill?

To find out how to quickly and easily make a sawmill from a chainsaw, you first need to understand what the device is. A sawmill is a unit that serves to process workpieces in the form of logs. The processing process includes sawing logs into boards and making beams. The factory device is large, hence the high price of such equipment.

In order not to buy a factory-type sawmill, in which the drive mechanism is a powerful electric motor that is powered by a voltage of 380V, there is a good alternative - this is a unit using a chainsaw. Moreover, you can use not only a chainsaw, but also an electric saw. Structurally, the sawmill layout will be identical. Except chain saws, you can also make a sawmill from band saw. The difference in their application is as follows:

If you make a sawmill with your own hands from a chainsaw, then such equipment allows you to cut round timber. The base of such a unit includes saw chain, the main disadvantage of which is education large quantity sawdust In addition, when sawing wood longitudinally, not only powerful tools are required, but also appropriate chain strength, for example, with pobedit or diamond coating, which help extend the life of the attachment
The mobile band sawmill is used for cutting large diameter logs. However, the use of such units also has its disadvantages, such as the spread of sawdust over a large area from the processing site. This drawback can be easily eliminated by connecting a flexible air duct to the chip separator. The main advantage of belt units is that the cut is thin, and therefore a small amount of chips is released

The photo below shows both options for sawmills using a chainsaw and strip fabric which were made by hand.

This is what it looks like simplest design of the unit in question, which is based on a saw with a chain cutting mechanism.

If the first option is considered mobile, then the second is stationary, and also requires high production costs. If the goal is to quickly and easily make a sawmill from improvised means using a chainsaw, then we will consider in detail how to implement the idea step by step.

This is interesting! A power saw can also be used as a powered cutting tool for sawing logs. Only one of the main disadvantages of electric saws is their low power, so the tool will not be able to cope with serious workpieces.

Why do you need a sawmill from a chainsaw on the farm?

With the onset of autumn, the sounds of gas and electric saws begin to be heard more and more often. This means that the firewood harvesting season is in full swing. However, for what purpose might a sawmill be needed when a mobile gas-powered tool does an excellent job of preparing firewood? Cutting wood when there is a fulfillment longitudinal cut, it’s easier with a chainsaw, but when the need arises to get their logs into boards, then for these purposes you can’t do without a sawmill.

The word sawmill itself means “saw” on a “frame”. Structurally, this is a machine on which it is mounted cutting tool(in this particular case, it is a chainsaw or electric saw). When firewood is being prepared for the winter, one often comes across straight trunks, from which, as they say, it would be a sin not to make boards. Another option is when you live in a rural area and want to start a business with minimal investment (open a sawmill). A chainsaw will also come to the rescue here, from which you can make a sawmill with your own hands. With this machine you can perform the following manipulations:

Saw logs into boards, which can later be sold or used to build a house, cottage or other outbuildings. Boards are always in demand and expensive building materials
Production of beams, which are also an expensive construction type building material, which can be obtained if you have a forest and a sawmill

During work, lumber remains that can be used as firewood for lighting solid fuel boilers. A mobile sawmill made from a chainsaw has the following advantages:

It does not take up much space on the site, so there is no need to construct an additional ceiling for it
It can be disassembled at any time to continue sawing trees.
Can be used both at home and in the field, for example, in the forest immediately after felling trees

However, all these advantages have portable models sawmills from chainsaws. If you plan to make a sawmill in the form of a machine, then it is not so easy to move it, so you can use it only in one place where it will be installed.

How to make a sawmill from a chainsaw

If you need a mini sawmill made from a chainsaw, then everything is simple here. You need to take metal corners and weld the corresponding structure. In this case, you only need to first prepare a drawing on which to plan the design of the final equipment.

The second option is when you need a home sawmill, the manufacture of which will require:

A chainsaw that is used as a powered cutting source
Mechanism for moving workpieces. This will eliminate the need for the sawyer to move around the workpiece, which is unsafe
A device for fixing workpieces in the equipment structure. It is necessary to fix the workpiece in order to prevent it from turning when exposed to the cutting tool. If you do not secure the log, it will rotate, which will reduce not only labor productivity, but also end up with a sloppy workpiece in the form of a board.

Having an idea of what it is homemade version device, you can begin to implement it. Here it should immediately be noted that it is possible to make a sawmill of any complexity, which, as they say, is “very handy.” However, the goal of this material is to show how to make the simplest sawmill using a chainsaw.

This is interesting! The main rule in manufacturing homemade sawmill from a chainsaw - this is to provide a mechanism for adjusting the thickness of the resulting boards. This action is realized due to the frame to which the tool is attached, as well as adjusting screws.

Drawings of a sawmill using a chainsaw photo

Before studying the manufacturing process of the device in question, it is recommended to first make a drawing or diagram. To do this, you will need to initially decide what type of device is needed - mobile or portable, as well as home or stationary. Below are several types of sawmill manufacturing schemes that are easy to make at home.

This is the simplest option for making a mobile machine for making boards of different thicknesses.

If the first drawing of a chainsaw sawmill involves the sawyer moving the tool itself along the workpiece, then the second option is more versatile and practical. The tool is mounted on a movable frame, and the workpiece is placed on a flat surface. After this, the required thickness of future boards or beams is set, which is done by raising up or lowering down a tool fixed on threaded slots.

The third option for a sawmill with a chainsaw as a cutting tool is a stationary machine. Making it is much more difficult than the first two, but it greatly simplifies the master’s work. All that is needed from the master cutting at the sawmill is to push the workpiece towards the rotating chain of the chainsaw. Using levers, the required thickness for the boards, which are obtained from the sawn log, is set.

Do-it-yourself chainsaw sawmill, instructions with photos

A homemade sawmill from a chainsaw is an opportunity to save a lot on the purchase of boards that will be needed when performing any construction work. Let's consider several options on how to quickly and easily make a sawmill from a chainsaw with minimal financial and physical costs.

Option for making a simple sawmill based on a chainsaw

The first version of a homemade sawmill is quite simple, so anyone can implement it, spending no more than a couple of hours on it. To implement this method you don’t even need a welding machine, so let’s get started. Initially, we prepare the necessary materials:

Hollow steel beams measuring 5x5 cm and 1 meter long. The number of such bars is 6 meters (it all depends on the length of the tool tire)
Connecting elements in the form of fastening bolts with a diameter of 8-10 mm in the amount of 10 pieces

When all the components for manufacturing the device are ready, you can begin.

First you need to make a lattice base from steel bars
The size of the base is equal to the length of the tool bar
This base is a guide when sawing logs
To secure the tool and adjust it, two bars are fixed perpendicular to the base
At the ends of the bars that are attached to the base, you need to make clamps to secure the chainsaw bar with eyes through which the chain will move freely

As a result, we get the following device, as shown in the photo below.

Specifically for the manufacture of this sawmill, a welding machine was used, due to which the costs of connecting elements were reduced. However, it can be done without welding, but using a drill. You can decide for yourself which is better, but in the end we get an expansion of functionality useful tool On the farm there are chainsaws. How this type of sawing equipment is manufactured is described in detail in the video.

The second option is how to make a sawmill with a chainsaw

Another simple option on how to make a sawmill for your chainsaw, which involves the use of the following consumables:

A channel measuring 10 by 5 and at least 5 meters long. Length affects the size of the logs to be cut. How larger size logs, the length of the channel must be appropriate
Steel corner size 5x5 cm
Steel tube up to 1 meter and diameter 15-20 mm
Fasteners in the form of bolts and nuts

The principle of manufacturing the second version of the sawmill is that the channel is a guide for the movement of the tool. A corner is used as movable rollers, which is located on the upper part of the channel. A tube is attached to the corners, which are rigidly connected to each other, and a chainsaw is fixed to it.

The photo shows what it looks like ready product for sawing logs. How to use it is as simple as making it. Place on the top of the workpiece, measure right size boards (thickness final product), start the unit and walk along the log from start to finish. The decisive role is played by the time that must be taken to correctly align the tool, but this disadvantage is compensated by the simplicity of the unit’s design.

The third option is to make a homemade sawmill from a chainsaw

Making a mobile sawmill from a chainsaw is not difficult and not expensive, unlike a stationary device. However, they have big drawback- this is the need to hold the tool in your hands or move it almost manually. Therefore, we will consider another option for making a sawmill from a chainsaw with your own hands, which is one of the most versatile.

The photo shows a model of such a device, which anyone can make. The design, although simple, requires a lot of effort to manufacture. It’s easy to use, for which you first need to place the log on a flat surface, roll the machine to the workpiece, set the thickness of the cut, and get started. The machine moves along the workpiece, sawing boards of the required size.

This is interesting! This type homemade device is something between mobile and compact chainsaw sawmills and stationary units, in which the tool is mounted on a movable base and moves along guide rails.

What kind of homemade products there are and how to make them, you now have an idea, so you can start implementing them. These are the simplest, lightest and most inexpensive chainsaw sawmills that anyone can make.

Varieties of homemade chainsaw sawmills

There are so many inventions, so many people, so we’ll take a sightseeing tour of different types homemade sawmills, and find out the design and application features.

The first version of the device, which is shown in the photo, is suitable for cases when it is necessary to cut not one or two logs, but several dozen. The convenience of using such a unit is that the workpiece is placed on the base, fixed, and after that the cutting tool moves along the rail track. Special design in the form of an arch on which the tool is mounted, it moves along rails. To set the cutting thickness of the boards, the arch design provides for adjustment of the position of the tool.

Simplified version of the first option. The simplicity of manufacturing this model lies in the fact that instead of channels, a steel angle is used, from which the base is made. A manufactured arch moves along the inside of the corner, on which the tool is fixed. The corners are connected by longitudinal plates on which the workpiece is located. A simplified version of a stationary sawmill made from a chainsaw allows you to not only quickly make it yourself, but also save on materials.

The third option for a stationary sawmill can also be made independently at home, but this will require a lot of consumables. The principle of operation of such a unit is that the gas-powered tool is fixed on a special movable frame. The bed is mixed manually by a sawyer along the outer part of the channel. To set the required thickness of the boards to be cut, the channel is raised or lowered thanks to a special mechanism.

How to properly saw boards on a homemade sawmill

If the master has mastered the manufacture of a homemade product, then figuring out how it works will not be difficult. a lot of work. However, when sawing you need not only skills and abilities, but also compliance with safety precautions. In addition, you cannot operate a chainsaw without protective equipment, which includes goggles, a helmet with headphones, gloves, special overalls and boots with an iron toe. The instructions for first starting up and working on a sawmill using a chainsaw are as follows:

First you need to check the installation. All connections must be secure and the tool must be firmly attached to the frame
Before attaching the tool to the machine bed, make sure that the gas tank and oil tank have sufficient fuel. Tanks must be full as the tool is operated at a 90 degree angle
After firmly securing the tool, you need to start fixing the log. Even if a mobile installation is used, the log must be securely fastened so that during the process of exposure to the tool, it does not move or vibrate
The required cutting thickness of the boards is set
The chainsaw starts only after it is secured to the stand. After this, you need to slowly bring it to the workpiece
Lock the chainsaw trigger at a speed above average and start cutting. When sawing you need to be careful, as impacts cannot be ruled out.
You need to move the chainsaw slowly so that the tool works at half the load.

The result of making your own sawmill from a chainsaw

If you set a goal to build a mini sawmill for your home, then you need to start first by making a homemade diagram. Based on the diagram, you can begin to implement the idea into reality. Making a mobile machine for sawing boards is not difficult, and every craftsman can handle it. To do this you need to have on hand necessary tool in the form of a grinder, drill and welding machine, Consumables in the form of fasteners, handles and screws, rollers, as well as main parts - angles, channels, tubes.

Then it's a matter of time and skill. When working at a sawmill, you need to take into account the following: in the design of a chainsaw it is better to use chains made of carbide materials with pobedite or pobedite applied to the teeth. diamond sputtering. This will extend the life of the chains and also eliminate excess stress on the tool when the teeth on conventional chains become dull. It is not recommended to cut logs when low temperatures, since frozen workpieces will dull the teeth of power tools even faster. Having a chainsaw on your farm, you should not limit yourself to its basic functionality, since this tool is capable of performing many useful work, replacing this expensive equipment like a sawmill. What other capabilities does a chainsaw have that can be expanded using special attachments? you can read it in .

Tools

An electric saw is an indispensable tool for summer cottage or in a personal home. She simply masters cutting thick branches, boards and different material made of wood. Even the most reliable tool has its own degree of wear, and from time to time it is necessary to correct small or large damage. Electric saw repair their with hands is possible only in certain cases and in the presence of certain abilities and equipment. Often the tool has to be sent in for service. But there are some breakdowns that can simply be corrected without the help of others.

Overview of the design of an electric chain saw

In order to master the ability to repair electric saws, you need to understand their design. The main element that cuts the material is the saw chain, which is driven by a motor. The chain itself is a collection of cutting links, which are fastened together by hinges. The chain moves along a plate called a tire. Do-it-yourself electric saw from a grinder -. This part is made from steel of the highest quality, which is not susceptible to chips, scratches and corrosion - this is the main indicator of the tool’s properties. Tires are classified by design:

welded;
solid with removable tip;
solid with a tip made of carbide materials.

A welded tire is something similar to a “sandwich” that is welded from 3 components into one, with all this a driven sprocket is riveted into the structure. One piece design with replaceable tip - 1 sheet product, normal for instruments long length. In such a tire, the main load falls on the roller bearing of the driven sprocket. The one-piece configuration reduces friction losses by 8-10%. If a tool with a solid tire made of hard alloy materials, then it is normally suitable for working with the highest loads, as well as for operation in conditions where there is a huge amount of sand, dust and dirt.

1. ELECTRIC CHAIN SAW FROM AN GRINDER WITH YOUR OWN HANDS. When working with an electric saw of any configuration, you need to keep in mind the possibility of the appearance of “ kickback" throwing the tool towards the person performing the work. This situation occurs if the very end of the saw bar rests on the material being processed. To avoid injury in such a situation, manufacturers equip saws with an automatic chain brake.

Review of possible malfunctions of electric saws

If the saw does not cut in, need to check availability of power, integrity of wires and connections.
If everything is fine in the power supply, you need to check the chain brake, which blocks the operation of the tool. To fix this problem, you need to move the brake flap to a different position.
If the measures described above do not turn on the saw, then need to check integrity of the cable and plug.
If the power of the saw has decreased or productivity has dropped, you need to change the carbon brushes, which are apparently worn out.
Quite often the chain begins to stop not immediately, but after a certain lapse of time. The longer the saw is used, the larger this temporary clearance becomes. To get rid of this task, you need to change the saw brake band, which has worn out over time.
Often, when the saw is operating, a nasty, ear-cutting sound occurs. This sound often occurs due to a lack of oil in the mechanism or due to contamination of the grooves that conduct it. A power chain saw is a saw, How to make a bird feeder with your own hands. Fixing the problem is simple - add oil and clean the grooves.
It is important to use only unique spare parts for repairs that are recommended by the manufacturer. If you use spare parts from third-party companies, this often leads to tool failure or unsafe situations.
If there is damage to the body, then for your safety, the saw must be sent in for repair.
You cannot replace cutting parts of the tool that are not recommended by the manufacturer or are not suitable for the design.

Sharpening a power saw

One of the elements of the saw that you need to monitor yourself is the chain. Electric chain saw 2 years of operation, is it worth it to renovate an apartment with your own hands? It must be sharpened preventively, since if this process is delayed, it will no longer be possible to repair the electric chain saw with your own hands. It must be sent to a service center, where it will be sharpened on professional machines.

Some rules for working with electric saws

Electric chainsaws are designed to operate at maximum speed and should always be operated at full throttle to improve performance.
You should not cut at a right angle away from yourself; you should hold the saw slightly at an angle from the body.
It is necessary to follow the instructions for repairing the electric saw, and also purchase only those spare parts which are recommended by the manufacturer.
Before transporting the saw, you must turn off the engine; keep the bar and chain behind you when carrying it; you must pack the saw in the casing before transportation.
Do not operate the saw above shoulder level as this increases the risk of an accident.
If the saw is jammed in the material, it must be removed from there very carefully. The buoyant force acting on the saw increases when the upper part is clamped, which is quite dangerous for the operator.
When working with a log framed by thin branches, you should act very carefully, since thin material in some cases is clamped by a tire and tilted towards the person performing the work.
It is strictly forbidden to use a faulty, unadjusted or incompletely assembled tool.
Before starting work, it is necessary to check the serviceability of the saw switch.
It is necessary to constantly monitor the tension of the chain, since if it is poorly tensioned, then the risk of it jumping off the guides increases, which leads not only to injury, but also to breakdown of the device.
Repair of Partner electric saws, like any other saws, is recommended to be carried out in a specialized service center, because do-it-yourself repair leads to serious problems in the future.

Homemade sawmills from electric saws: design options

Among all the variety of homemade products made from electric saws, sawmills are the most popular and widespread product that craftsmen have been producing for many years. Factory analogues of such devices are quite expensive due to their high performance. They are capable of processing thousands of cubic meters of timber per day of operation. When there is neither such a scale of woodworking nor finances, you can pay attention to one of 3 types of homemade sawmills:

tape; They have a complex design, but are adapted to any working conditions.
disk; Quite easy to assemble, but not reliable, which is why they are in demand among amateurs. Circular sawmills based on electric saws are quite common in everyday life, productive and versatile in the tasks they perform;
chain

In view of this, we will dwell in detail on their manufacturing technology.

Circular sawmill from an electric saw: detailed description and drawings

Before making a homemade sawmill from an electric saw, you need to decide on:

the length of the materials that will be processed on this machine;
volumes of workpieces;
future homemade location.

Special attention should be paid to the choice of disc blade. Discs with a size of 400-500 mm, which are most often used in modern circular saws, are more than suitable for these purposes. And the problem with sawdust can be solved by using a disk with a minimum thickness.

Construction of a circular sawmill based on an electric saw

The design of any homemade sawmill based on an electric saw implies the presence of:

frame element - a load-bearing part that connects all other parts together;

motor part - it is advisable to focus on three-phase modifications of electric saws: household models powered from a 220 V network may be low-power;
cutting set - the disk is installed in one of the planes - horizontal or vertical;
load-bearing unit - for everyday tasks, an ordinary workbench or table on which the logs will be fed by hand will do. For more complex design complemented with a mobile carriage;
adjustment mechanism - controls the electrical circuit of the homemade product, starts and turns off the motor. Most often located on the frame.

Assembly sequence

After the drawing of the future sawmill has been approved and corrected, they proceed to the installation of its leading working units:

installation of the frame frame - its dimensions are selected individually, taking into account the diameter of the disk and the dimensions of the motor. 2 bearings are attached to it and 4 holes are drilled for aggregation with an electric motor;
the plane along which lumber will be fed. For small-scale work, you can use a ready-made stationary workbench or work surface, which must be installed strictly horizontally. It is very important that its longitudinal axis corresponds to the axis of the frame base;
movable carriage - its approximate size should reach 1 m. Mobility will be ensured by wheels, which will be installed at the end of the corner;
aggregation of the motor with the disk - it is better to give preference to those sawmill designs where the height of the blade block could be adjusted manually. To do this, two pipes are connected to the carriage, to which a metal channel is welded. Through metal linings they are attracted to the pipes by clamps. Raising or lowering will be done by two steel rods. The movable position of the engine will be ensured by bicycle sprockets connected to the ends of the profile with the motor, connected to it through a threaded rod.

To improve the results of your efforts, the homemade product can be strengthened with a second circular knife. As in industrial analogues, their location must be strictly perpendicular to each other. For sawmills with a power of more than 3 kW, an additional traction device is not required. Otherwise, a second motor is taken and a second drive is created.
