Do-it-yourself grinder attachment for a chainsaw

Homemade grinder attachment for chainsaw

To make a homemade device, you need appropriate pulleys, a bearing assembly with a shaft, a tire, and a belt.
According to reviews from the owners, it is quite difficult to create such a device with your own hands; you should prepare drawings and diagrams and make the appropriate calculations. If you opt out of the tire option, you can use an adapter to mount the cutting wheel directly on the clutch. At the same time, chainsaw manufacturers warn against using various adapters. This is because the saw is capable of delivering torque up to 14,000 rpm, and the sanding disc is designed to operate at 7,000 rpm. With such intensive use, disk destruction is inevitable, as mentioned above. The only way out is to significantly reduce the speed of the chainsaw by installing a gearbox.

This installation method, which is not entirely safe, is presented in the video review:

In fact, the main advantages of a chainsaw grinder are rational mobility, low cost and high power. It is very convenient to use the grinder attachment in non-electrified places. If you choose between a homemade device and a factory device, then it is wiser to give preference to the latter option, which fully complies with safety requirements.

Before converting a chainsaw into an angle grinder, you need to responsibly weigh the pros and cons, realistically evaluate your technical training and the real need to implement such a project.

Features of the grinder attachment for chainsaws

With the help of such a mechanism, you can combine as many as two in one device - the gasoline power of the main unit - the saw itself, and many advantages of an angle grinder, better known as an angle grinder. This combination can be extremely beneficial if there is a need to carry out cutting work with various materials and structures (not wood), and there are no power sources nearby to which a regular mains angle grinder could be connected.

A gas cutter made from a saw with an attachment can be used to cut the following materials:

metal;
natural stone;
brick;
concrete and reinforced concrete structures.

In addition, they are often used for cleaning weld seams. With most of the attachments available today, cutting wheels - reinforced or diamond - and circular saws are used.

The main advantages of a grinder chainsaw

Is it worth spending money on an additional device to modify the power unit? What advantages will you get if you compare this type of tool with a conventional cutting tool?

The first important advantage of using the device is mobility. Sometimes you have to work in conditions where it is impossible to stretch wires to connect an angle grinder, or in conditions where there is no electricity, then a chainsaw-angle grinder will come to the rescue

Another important benefit is saving money. On average, you need to spend more than 7 thousand rubles on an average grinder. On the other hand, you will spend about 2 thousand to purchase a device or make a nozzle yourself.

Consider the power of the tools. Powerful grinders are considered to be those that have indicators of 3 kW, while chainsaws are capable of producing about 4 kW, but even this is not the limit, because professional ones demonstrate an indicator of 5 - 5.4 kW.

The nuances of using the nozzle

When considering the advantages of the grinder attachment, do not ignore some nuances:

Do not use the gas cutter indoors, as its exhaust is toxic;
for small-scale work (and when you need to make a precise small cut), a chainsaw with a device will be too cumbersome;
the air filter of your power unit will become heavily clogged due to metal dust floating in the air;
Compared to an angle grinder, a chainsaw with an attachment is heavier, which makes it inconvenient to manipulate for grinding.

Pros and cons of the solution

Various types of hand-held electric and gasoline tools are suitable for making grinders. The simplest and most convenient option is a device assembled on the basis of a saw with a chain. Advantages of homemade devices:

Great power. If we compare a homemade nozzle with factory models, then its power is 2 times greater.
Independence. The tool does not require electricity, so it can be used anywhere.
Easy assembly. All the necessary tools and materials can be purchased at the store or searched on your farm.
Affordable price. If you compare it with a ready-made tool, then you will need 2 times less money to assemble an angle grinder.

Despite all its advantages, the tool has a number of disadvantages. The air filters of the grinder become clogged with metal dust. Because of this, the engine gradually stalls and fails. A person can also get injured from using an angle grinder. Sometimes during operation the disks cannot withstand the load and burst. Under the influence of traction they fly apart. To protect yourself from injury, you need to choose discs up to 115 mm in diameter and use a protective cover.

Factory chain saw attachments for an angle grinder

For those who do not like to work a lot with their hands or due to poor knowledge of the structure of equipment and tools, some manufacturers of gardening and repair equipment produce special ready-made attachments. In the kit you will also find all the necessary fastenings. This is a very convenient option, but you should carefully select attachments so that they can work harmoniously with the power unit against the background of technical indicators and characteristics.

You can buy such kits at a regular construction supply store or supermarket, branded saw equipment stores, or even at markets. In addition, you can find chain saw attachments for grinders on Aliexpress, Amazon and eBay.

Advantages and disadvantages

An angle grinder attachment can be made from a variety of hand-held gasoline and electric tools. But the simplest and most convenient method is using a chain saw.

Advantages of the device:

they are autonomous, that is, a gasoline device will not depend on electrical power, like electric angle grinders, which, on the contrary, need electrical sockets and extension cords;
the nozzle can have very high power;
it is easy to design and assemble, the main thing is to have the necessary drawings and tools, which can be purchased inexpensively at a hardware store;
the price of homemade equipment will be cheaper than the cost of the original.

The disadvantages of homemade nozzles include the following:

they are too sensitive to metal dust: chainsaw filters begin to become clogged and fail, and the engine may deteriorate: first it stalls, and then it will not be able to maintain speed and will wear out;
grinding discs can constantly break and fly around, and this is very dangerous for the worker himself and the people around him.

To make your device more secure, you need to follow some rules:

limit the engine speed of a gasoline saw;
you need to use disks that are designed for increased rotation speed;
work must be carried out only using a protected casing;
the design must have an inertial brake;
You need to use models that have a kickback protection function.

The angle grinder attachment has:

a pulley that can wear out or break, so you need to monitor the device and, if necessary, change the pulleys on it;
In order for the nozzle to work, it must have an adaptive key, consisting of a metal plate, having a hole and 2 steel pins;
a special V-belt can transmit torque from the engine to the cutting wheel (the belt is a consumable material);
For attachments such as angle grinder 1 and NK - 100, spare bearings are needed, because the bearings themselves are a consumable item.

Advantages and disadvantages of homemade electric saws from an angle grinder

low level of safety for the health and life of the operator working - in homemade products there is no protection against kickback, which in factory electric saws is taken over by the inertial chain brake. And this increases the likelihood of injury and injury;
fragility of tire-chain elements due to the lack of automatic lubrication. The only way out in this situation is to periodically dip a homemade saw into a container with chain oil;
high risk of motor overheating from an angle grinder due to overloads and prolonged use.

The second reason can be considered the desire to have a multifunctional tool that will help facilitate numerous tasks on the farm. The undeniable advantage of such a homemade device is the space saving. After all, an additional attachment takes up much less space in a shed or garage than a full-fledged device.

For remodeling, you can use absolutely any brand of grinder. The only point worth paying attention to is that the factory attachments may only fit a limited number of models, so when purchasing, be sure to check whether your angle grinder is suitable for the selected attachment.

Rules for using a homemade grinder

When using a homemade tool, you need to follow a number of important rules.

Their list includes:

When operating the device, the operator's hands and eyes must be protected. In addition, to work with the tool you will need to wear a suit made of thick fabric. It must be remembered that the cutting disc of the grinder is quite fragile to break, so at any moment a part of it can break off and cause harm to the operator;
before using the homemade product, it will need to be equipped with a protective casing;
You cannot install a large cutting disc on an angle grinder made from a low-power chainsaw. This will increase the load on the engine of the garden tool and lead to an increase in the amount of fuel consumed.

The tension belt plays an important role in the overall operation of the homemade device. Not only the effectiveness of the tool, but also the safety of the operator depends on its tension. To adjust the tension level of the element, you need to grab its central part and try to rotate the belt around its axis. A correctly tensioned belt will turn no more than 900. If this value is greater or less when turning the belt, then it will need to be adjusted.

Stationary circular

Many different problems can be solved with the help of a homemade circular grinder. Such a machine will become an indispensable assistant when renovating an apartment, making furniture and for many other men’s tasks. You can buy a ready-made circular saw, or you can make it yourself.

You don't need to have any special skills to do this. It is enough to be able to use hand tools and have the necessary minimum materials. Before we talk about how to make a circular saw from a grinder, let's consider the general design of the machine.

The nozzle is a grinder and must be used according to the manufacturer’s recommendations and in compliance with safety precautions. In practice, these recommendations are neglected, which often leads to injury. Let's consider the main points that should be taken into account when working with a chainsaw - an angle grinder.

The operator's hands and eyes must be protected during operation. Goggles and gloves are a must, but it wouldn't hurt to wear a suit made of rough material. Cutting discs are thin, fragile to break, and while they can be easily controlled with an ordinary grinder, it is not so easy to do this with a saw. The disc can wrap and break, and pieces can fly away and cause injury.
It is not worth installing a large-diameter cutting disc on a chainsaw with a power of less than 1.5 kW; the engine will cope, but will work at the limit and there will be noticeable drops in speed.
It is prohibited to work with the protective cover removed.
The drive belt between the pulleys must be properly tensioned. You can check the tension as follows: grab the belt in the center and try to turn it around its axis. If the belt turns only 900, then it is tensioned correctly; if it is more or less, then adjustment is necessary.

You can use a grinder as a working mechanism in stationary conditions. The bed in this case will have a slightly different design. The stationary option implies the presence of free space and a large amount of work. Therefore, the entire structure can be made more solid, more massive, and, therefore, more reliable.

The frame of the bed can be made from a corner using a welded joint. Bolted and other types of detachable fasteners lose their grip due to constant vibration, and the structure begins to wobble.

A desktop made of a wide board or thick plywood is attached to the top of the metal frame. The workpiece will move along it. The stop angle is equipped with a movable mount for adjusting the cutting width.

Currently reading: Husqvarna saw 137 instructions

On the side of the machine there are controls: a socket and on/off buttons. In the stationary version, it makes sense to exclude the key on the body of the angle grinder from the diagram. If there is enough space, a high-power sander can be used as a drive.

How to make an angle grinder from a chainsaw

The combination of an attachment with a saw not only allows you to effectively cut various materials, but also carry out work regardless of the availability of an electrical outlet. After all, an ordinary angle grinder, angle grinder, or grinder, as the tool is simply called, is equipped with an electric motor, and therefore is completely dependent on the power supply source.

Demand creates supply, and grinder attachments for chainsaws of various modifications have appeared on sale. And folk craftsmen mastered this niche of transformation much earlier. The most common tools used for alterations are Druzhba, Shtil, and Ural.

Finished nozzle - grinder

Creating an angle grinder from a chainsaw is one of the first places in the popularity of such transformations. However, before installing it on the saw, you should understand the features of the transformations and possible failures. As a rule, a ready-made device can be purchased without any problems at the appropriate store.

It should be taken into account that the attachment is not a universal device; it is chosen for a specific modification of the saw. Often, manufacturers do not indicate in the instructions which models the nozzle is suitable for or provide an incomplete list. To ensure compatibility, compare the diameter of the saw crankshaft with the diameter of the attachment pulley, after first removing the clutch from the saw.

DIY chainsaw crafts

In the hands of craftsmen, an ordinary chainsaw, originally intended for sawing wood, becomes a truly multifunctional device.
At the same time, the breadth of its application is simply amazing in its diversity. There are various types of special attachments on sale that significantly expand the capabilities of chainsaws. These include the following attachments: a gas cutter, a decanter, a pump for pumping water, a motor, a brush cutter, a snow blower and others. But, despite this, many craftsmen remake chainsaws on their own, using scrap materials. Almost anyone with a little knowledge of technology can make homemade chainsaws with their own hands. [contents]

Rework principle

The basis of almost any homemade chainsaw is its use as a universal drive that can be used for a huge number of different devices. The scope of their use is very wide: cutting stone and metal, pumping water, removing snow, drilling wells and holes, driving, moving various objects, swimming and even flying.

Realize the potential capabilities of a chainsaw using a variety of accessories and attachments. The basis of any modification is the simple principle of engine power take-off: the device necessary for the master is connected to the output shaft. The presence of a powerful motor, compact dimensions and relatively light weight of this tool, autonomy and the ability to work in almost extreme conditions make its capabilities truly limitless. Of no small importance is the practical design of the clutch, which protects the components and systems of the saw from damage and overload. The tool, made from a chainsaw, is distinguished by its tightness, so it can be used in almost any position.

What can be made from a chainsaw

All homemade products can be divided into 2 groups:

the simplest devices (grinder, ice screw, pump, winch, walk-behind tractor, outboard motor, bicycle, moped);
more complex mechanisms and objects (sawmill, snow blower, snowmobile, snowmobile, power plant, helicopter, solid forged knife).

To manufacture all of the above devices, you can use various brands of chainsaws. When choosing them, you should take into account the required power for normal operation of the modification. Most often, the following brands of chainsaws are used for the manufacture of various devices: Druzhba, Shtil, Ural.

The simplest homemade chainsaws

Below are various options for devices made from chainsaws. Anyone can use such ideas in their own household. From a chainsaw with a small amount of additional materials you can make:

Bulgarian. The main system of such a device is a bearing assembly with a shaft. A driven pulley is installed at one end of it, which rotates using a V-belt. A mandrel for cutting wheels is attached to the other. Depending on their brand, such a grinder can cut stone, metal, brick and other building materials.

Additional Information

Compared to a regular saw, an angle grinder:

works faster;
takes up less space;
increases work productivity;
noticeably lighter;
lasts longer (if the tool is used correctly).

To cut wood, you can use special cutting discs with a chain. However, it is very difficult to find the type of nozzle suitable for a particular model. A sawing wheel that combines the features of a disc and a special chain, suitable for processing boards no thicker than 4 cm

Extreme caution must be used when using it. It will not be possible to run the angle grinder at higher speeds than the disk allows

There is also a serious limitation on the size of the processed workpieces. To increase it, you have to use larger disks. However, their use is limited by the size of the insulating casing. And if it does not allow you to install a 125 mm nozzle, problems will arise. But peeling wheels connected to chainsaw chains allow you to remove bark and branches from the trunk.

This device will also help prepare a log house no worse than a high-quality ax. But you should not use such a disk instead of a cutting wheel. The cut line will be jagged and too much wood will be wasted. Another type of attachment - a disk with large abrasive grains - is no longer intended for primary processing, but for rough milling. This accessory is safer than a hand rasp.

For more information about chain saw attachments for an angle grinder, see the video below.

Ready-made attachment - grinder for chainsaw

Today, an attachment for a chainsaw, including the “grinder” type, can be bought without any problems at any petrol tool store. There are no problems with installation either, since detailed instructions are supplied with it, after studying which you can install the grinder on the chainsaw yourself, except in cases where the attachment is chosen incorrectly.

Important: the grinder attachment is not universal; it must be selected for a specific chainsaw model. Manufacturers of attachments do not indicate in their documents a complete list of chainsaw models for which they are intended, which makes it difficult to make the right choice

How to choose a grinder for a chainsaw

When choosing an attachment for your tool, first of all, you need to read its technical documentation. If your model is not listed in the list of chainsaws for which it is intended, this does not mean that an angle grinder attachment cannot be installed on it.

To check compatibility, you need to compare the diameter of the chainsaw crankshaft with the diameter of the mounting hole on the pulley from the attachment kit (you will need to remove the clutch from the chainsaw).

The drive pulley of the nozzle can have several types; we’ll talk more about the types a little later. When choosing, it is necessary that the type of the chainsaw drive sprocket and the attachment pulley match, otherwise it is not possible to install the pulley instead of the clutch.

Types of attachment pulleys - grinders

There is no official classification of chainsaw pulleys and clutches by type, but it would be more convenient if there was one. We will try to explain the differences between the pulleys in clear language and show photographs.

Pulley type “Shtil 180” is a closed cup for installation in a regular place, instead of a clutch, combined with a pulley. The pulley is non-separable, the diameter of the mounting hole corresponds to the diameter of the crankshaft with a needle bearing installed on it. Used in Shtil MS 180, 170, 250 chainsaws.

A pulley without a cup, installed on the chainsaw drive sprocket, without removing the clutch. May have several options, depending on the sprocket pitch. The advantage of this type is ease of installation (for Shtil MS 180 with a closed clutch cup, in those chainsaws where the clutch is open, you will need to remove it for installation) and low cost (can be sold separately as spare parts). This pulley is more universal and can be used in chainsaws Husqvarna, Partner, Taiga and other Chinese analogues.

For clutches in which it is possible to replace the drive sprocket, these are most often installed on professional chainsaws; manufacturers make special pulleys. Unfortunately, we did not find a photo of a pulley with such a landing, but there is a photo of the clutch and replacement link, by looking at which you can understand what it looks like.

We looked at the most popular pulley models, but this is not all that can be found on sale.

Now we invite you to watch a video in which the master shows and explains how to make an angle grinder from a chainsaw using a purchased attachment. By the way, this video uses a rarely used and expensive pulley; it could have been replaced with a pulley without a cup, which we talked about above.

DIY installation on a chainsaw

Not everyone knows how to install a grinder attachment on a chainsaw, so we will tell you more about this.

Installation work should begin, oddly enough, with cleaning the chainsaw. It is necessary to remove the side cover, bar, chain and blow out the chainsaw with compressed air; small particles of wood are compressed and accumulated under the side cover, which can get into the bearing when disassembling the clutch.

Next, you need to unscrew the spark plug and limit the piston stroke using a piece of thin and dense rope with knots tied to it. To do this, you need to insert the rope into the cylinder through the spark plug hole. These manipulations are necessary in order to block the stroke of the piston and, accordingly, the crankshaft as safely as possible and unscrew the clutch.

Next, the clutch cup is removed from the crankshaft and, depending on the type of pulley attachment, it is either changed or a pulley is installed on it instead of the drive sprocket. Assembly is carried out in reverse order.

Now let's move on to installing the attachment itself - the grinder. It is mounted in place of the standard tire, nothing complicated, you just need to install the attachment on the two mounting screws, close the side cover and tighten it with the screws.

At the final stage, the belt is tensioned. We described above how to check the tension.

Table saw

Trimming, that is, cross-cutting boards or bars at right angles, turns out better if you use a special device.

You can also make such a machine from a grinder with your own hands.

To do this, a grinder with a disk for wood is fixed on a rotating bar perpendicular to the direction of the length of the board so that the plane of the disk is directed strictly vertically. One attachment point should be located in the area of the gearbox, and the second should be at the opposite end of the machine.
The gearbox housing has threaded holes for attaching standard handles. Using the corners and these holes, the grinder must be attached to the moving part of the machine.
The back of the body is attached to the board with a clamp. The blade guard can be used on any power tool of a suitable size.
Closer to the vertical support you need to secure the thrust angle. It should be located strictly perpendicular to the plane of the disk, both in the vertical and horizontal directions.

The spring at the rear end of the bar is used to return the miter saw to its original position after finishing the cut. The horizontal table must have a transverse groove into which the disk fits when cutting the board. The diameter of the disk is chosen based on the width of the boards. This way, trimming can be done in one go. The main thing is that the inner hole of the disk must coincide with the mount on the gearbox axis.

Sometimes there is a need to change the width of the board or the thickness of the block. The best option for such work is a circular saw, especially if there are a lot of boards. For cutting boards of short length (1-2 m), a tabletop version of a circular saw is very useful. It is not necessary to buy such a machine; you can make it yourself from the same grinder.

The design of a circular saw is much more complex than a miter saw. The contact time of the saw blade with the wood is quite long, therefore the reliability of attaching the grinder body to the frame should be higher.

Currently reading: Cutting out crafts from plywood with a jigsaw, drawings for a miracle jigsaw

This is what one of the options for a tabletop circular might look like.

The photo shows that the desktop consists of two planes:

the upper table is designed to advance the workpiece;
The lower one serves as a stop for the sander.

The disc passes through a groove in the top surface. If the angle of contact of the two planes is provided with rotary hinges, then it will be possible to adjust the working height of the saw blade to reduce the area of rubbing surfaces.

The head of the bolt with which the angle grinder is secured is clearly visible on the top surface of the table. The protruding bolt limits the width of the board being processed. You can cope with this problem by laying another layer of plywood.

The stop angle must have the maximum possible length to prevent the board from deviating from the cutting direction. It is better to fasten the corner in such a way that you can change the working distance between it and the disk: then the width of the cut part will also change.

What else should you pay attention to?

Despite the fact that DIY equipment is increasingly becoming an integral part of our everyday life, leading manufacturers of both grinders and saws still strongly advise against such modernizations completely.
And the point here is not at all a matter of competition between production technologies and handicraft production. This warning is based on the fact that modern chainsaws have a very huge torque, several times higher than the same parameter for an angle grinder. What could this threaten? Firstly, the grinding disc may not withstand such a load and fall apart right in the middle of work. Accordingly, the tool itself will lose its functionality and may fail.

But this is not the worst thing that awaits lovers of homemade products. The worst case scenario is associated not only with damage to health, but also with a threat to the lives of both the operator himself and those nearby.

Therefore, before deciding on such an improvement, it is worth weighing all the pros and cons, and only then making rational conclusions and actions.

Video reviews

Below is a video review demonstrating the chainsaw attachment

Alexander Mikhailovich:

Getting two tools in one is a great idea. A friend who is well versed in repairing such equipment helped me implement it. We used all the necessary parts from the angle grinder and got a multifunctional device. It works great, but I realized that it is better to install a small 115 mm disk, the work will be more efficient.

Advantages: not expensive, multifunctional device.

Disadvantages: Must be used with caution as this is a homemade device

Let's cut everything around or grinder on a chainsaw

The cutting disc is used in a large size, this is taken taking into account the maximum speed that the chainsaw can produce.

List of materials:

- plywood; - wood screws; — bolts with nuts; - thin sheet metal; - Sheet steel; - a piece of leather or thick rope; — square steel pipe; - cutting wheel.

List of tools:

- rivet gun; — drill and drilling machine; - jigsaw; - lathe; - wrenches, pliers, clutch release wrench, spark plug wrench; — belt grinder; - Bulgarian; — semi-automatic welding machine or inverter; - wood glue; - pencil, ruler, tape measure, paper.

Homemade manufacturing process:

Step one. Preparing the grinder

First of all, remove the tire from the angle grinder, then you will need to remove the clutch along with the sprocket. This task can be quite difficult, since often the clutch is tightly stuck to the shaft and cannot be unscrewed without a service center. To try to unscrew the clutch, you will need a special wrench, it is similar to the one used to unscrew the nut on an angle grinder. Remove the top cover from the angle grinder and remove the spark plug.

Stick as much rope or a piece of leather into the candle hole as you can pull out. This will allow you to block the piston and try to unscrew the clutch. If it works, great!

How to convert a chainsaw into an angle grinder?

Before you make a grinder from a chainsaw, you need to prepare the components required for the job.

To assemble a homemade product, the manufacturer will need:

engine from a chainsaw - it is important that the internal combustion engine has a reserve of power, which will be sufficient for sawing hard metal products. It is best to use a motor with a power of more than 4 liters

With.; working mechanism - a unit from any old household grinder will do. It must be fully operational, otherwise it will not withstand the load from the engine; 4 guide rails, length from 40 to 50 cm; belt; 2 reels.

The work algorithm looks like this:

First, the belt used must be installed parallel to the standard chainsaw bar;
After this, you will need to install a pulley on the utility saw. You can attach the element to the standard drive sprocket of a garden tool;
Then, from the working mechanism of the old grinder, you need to remove the gear built into it and carefully grind it;
After this you will need to assemble the pulley. It must be attached to the general structure of a homemade grinder by welding;
The 2 guide bars remaining from the manufacturer must be shortened. As a result, they should fit tightly into the seats and not interfere with the operation of the belt while it is moving. It is best to sharpen one of the used tires for installing the working mechanism from an old grinder;
Next, all remaining parts of the structure will need to be welded together. After this, the manufacturer will only have to buy cutting wheels and start using the grinder.

When using homemade products, you need to constantly monitor the condition of the air filter from the chainsaw. It must be kept clean, otherwise the homemade device will quickly fail.

DIY Instructions

Sawmill from chainsaw Ural

Before starting work, a drawing is selected or created, or at least a sketch of the future product. It is advisable that the dimensions of at least the main parts be indicated. This will make the work much easier and faster. It will be possible to immediately cut the workpieces to length, and then begin assembly.

The general appearance and capabilities of the future unit can be selected and seen both in practice, using the example of band saws or chainsaws, and on the Internet in numerous videos on this topic. When choosing options according to the type of which you plan to make your own version, it is better to choose the simplest ones, with a minimum of complications and details.

This video shows the simplest device of this type. We see a pulling cable that the operator winds with the help of a handle, ensuring that the chainsaw is pulled along the log. But at the same time it is clear that the operator not only tightens the cable, but also simply moves the unit by hand. Obviously, a sawmill of this type can be made either with such a broaching device, or in an even simpler version, without it. Then the chainsaw is moved by hand.

The main requirements for any design and material:

Sufficient strength.
The absence of large backlashes when the working unit moves along vertical and horizontal guides.

It should be remembered that excessive strength makes the entire structure heavier and more expensive, and too tight a fit of moving parts in the guides eliminates backlash, but can lead to jamming during operation.

Having experience, you can start work without a drawing, or with a simple sketch - a sketch. Work without a drawing is carried out blindly, and unexpected errors often emerge. In addition, all dimensions will have to be remembered or written down on paper. And recording dimensions indicating the location of parts automatically leads to the creation of at least a simple sketch.

After selecting or creating a drawing (sketch), the blanks are assembled. A set of necessary rentals, fasteners and other necessary parts is assembled.

Next, the rolled metal is cut to length, and the blanks are assembled until the entire structure is ready.

We recommend watching the video below for more details on how to make a sawmill from a Ural chainsaw. The author talks in detail about all the manufacturing steps and also gives dimensions. We recommend watching this useful video.

Mini sawmill from Shtil chainsaw

Such units are assembled in exactly the same order and principle as using chainsaws of other brands. But there are a few differences.

The dimensions and shape of the modern Shtil chainsaw are completely different from those of Soviet chainsaws. Therefore, when attaching the chainsaw itself to the frame, fasteners of a different shape and size are used.

When designing, the power of the unit is taken into account. For example, the Shtil MS 880 model with a power of 6.4 kW (8.7 hp) with a bar length of 70 or 90 cm can cut thicker logs of great length. Consequently, in order to use the unit to its fullest, a frame of greater width and length is designed.

How to make a Logosol type sawmill based on the Shtil MS 660 professional chainsaw is shown in the video below. The manufacturing stages are not described, but how it is constructed and the operating principle of the main components is clear.

Portable sawmill from Druzhba chainsaw

When manufacturing a sawmill using this unit, the features of the model are also taken into account. For example, the less powerful “Druzhba 2” is suitable for trimming thin gauges (understock) and does not require a wide and powerful bed. “Druzhba 4” is capable of sawing larger logs, and this is also taken into account during the design.

If the bed is being prepared for any chainsaw, it is advisable to choose a size that is medium in length and width. The mounting location of the power unit must be designed in such a way that a chainsaw of any size and power can be mounted without problems.

We also recommend reading an interesting article about what other useful things can be made from a Druzhba chainsaw.

We recommend watching an interesting video about what type of sawmill can be made using the Druzhba 4 saw. The author talks about how its device works, the principle of operation, as well as the nuances of making it yourself.
