This article contains an overview of the most popular devices and removable attachments that allow you to use a chainsaw as a grinder, wood splitter, wood cutter, drill, outboard motor, pump and other types of specialized equipment.

Thanks to a variety of attachments, the chainsaw is an indispensable all-purpose tool.

How to work with a homemade device correctly

The safety rules when working on such devices are the same as for any woodworking machines. The operator and bystanders must not approach the cutting blade. It is undesirable to work tired, with reduced reaction. Common sense should be used. Clothes should be buttoned and pulled up, without loose hems that could get caught in the chain.

If there is a wide spread of sawdust, you should wear safety glasses. When working for a long time, it is advisable to wear headphones to protect against noise.

Technical features:

• Do not put pressure on the cutting unit. The saw advances as sawdust is removed from the cut, without effort.
• Do not use chains with dull teeth or tires with worn grooves.

Care and maintenance of the entire chainsaw is the same as for normal cross-cutting use. But they are more careful to ensure that the engine does not overheat due to prolonged operation.

Chainsaw attachments: their purpose, advantages and disadvantages

A gasoline saw is a universal tool that has rich functionality. In the household and at the dacha it is simply priceless. Thanks to the use of additional attachments and accessories, the scope of application of this tool can be significantly expanded.

Attachments can be purchased for such chainsaws as Stihl, Husqvarna, Partner and other models.

No other tool can compete with the capabilities of a chainsaw. In combination with a certain attachment, it can be used as a drill, a pump, and even a boat motor. If necessary, this unit can pump out water from a well, as well as cut stone and metal. Some manufacturers have even managed to make a trencher out of a chainsaw, although the cost of such units is very high.

Chainsaws are equipped with powerful and at the same time compact engines that are quite unpretentious to use. In combination with a diaphragm carburetor and a sealed fuel supply system, such a tool is capable of performing a wide range of work. The ability to connect different types of nozzles is ensured by the output shaft, which has a special design.

On a note! Most of the components are designed for branded instrument models. These are mainly attachments for Stihl and Husqvarna chainsaws. The range of additional accessories for budget models is very limited.

Drive Link Shank Thickness

Along with the pitch and number of links that determine the length, there is such a parameter as the thickness of the chain. It is also very important because the bus-net pair correspondence must be strictly correlated. If the shank is too thick, it will jam in the groove of the tire or will not fit there at all. A chain that is too thin will vibrate freely in the groove. This will increase the risk of slipping and injury. Trying to compensate for vibrations, an inexperienced user will overtighten the chain, which will lead to accelerated wear of the saw set.

The easiest way to measure the shank is with a caliper. However, this should be done only on a chain that has not worked much - very worn copies are worn out and ground down, and the value may be taken incorrectly. It’s better to go online and read the specifications or consult a store.

The thickness of the leading link has also been standardized for a long time and is represented by the following values

Benefits of using detachable chainsaw attachments

Replaceable attachments, unlike a whole set of tools for various purposes, take up minimal space, so you don’t have to set aside a special room for storing them. If you have the appropriate skills, replacing a standard saw bar with any removable device can be done in just a few minutes.

The attachments take up little space and are easy and quick to change.

Buying attachments is more economical than purchasing a whole set of tools. Removable devices eliminate the need for additional equipment. When it comes to buying an angle grinder, the price of an attachment for a Shtil chainsaw will be 2-3 times lower. Moreover, branded models are almost in no way inferior to a highly specialized instrument with a similar function.

Using attachments allows you to recoup the cost of purchasing a chainsaw much earlier. If earlier this tool was used exclusively for cutting wood, today, thanks to removable devices, it can be used to successfully solve many construction, household and economic problems.

The saws have a very powerful gasoline engine, which is more efficient than the electric motors of highly specialized tools. There is also no connection to an outlet, making this unit mobile and can be used in the field.

If you have the necessary skills and knowledge, you can make removable devices yourself. To create attachments for a chainsaw with your own hands, you will need sandpaper, a welding machine and spare parts from old tools, for example, a pulley, belts, chains, shaft, etc. On the Internet you can find many recommendations and step-by-step technologies for making such components.

Thanks to attachments, you can save on the purchase of expensive equipment.

Precautions when choosing chainsaw chains

Changing the chain must occur in strict compliance with technical parameters. If there is no classification, then you need to know the following data:

• number of leading links;
• the thickness of the guide that fits into the groove of the tire;
• saw brand.

The new chain should fit freely onto the sprocket, and the guides should fit into the groove of the bar. After adjusting the tension, it should rotate freely without wedging. This will indicate the correctness of the selection.

There are well-known global manufacturers of chainsaw chains that produce decent products from the required steel. It is advisable to buy similar products, since Chinese-made products are of questionable quality, and in the best case, there will be a rapid loss of the ability to cut wood, and in the worst case, the chain may break under heavy loads.

When purchasing a new product, according to individual criteria, you should be wary of various promotional products with a low price. There are certain cost limits for such devices

Thus, professional-grade chainsaws with a pitch of 3/8” and higher cannot cost less than $1,000. This is due to the use of the highest quality components both in the equipment itself and in the circuit.

The modern market has a huge selection of chainsaws, which are positioned as professional, costing about $100-200. It is clear that this tool will soon become unusable. The term “semi-professional” has recently been coined. In fact, there are no chainsaws with this level. There are household saws for professional work related to wood. This should be known and taken into account.

Saws of a serious level are produced for multifaceted applications. They involve the use of chains with different pitches, which makes it possible to carry out any work. Naturally, replacing chains in these devices means replacing the sprocket; the only difference is the ease of installation and the ability of the engine to pull links with large pitches.

Why it is not recommended to connect attachments to a chainsaw

Using nozzles has certain disadvantages. This is primarily due to operational and technical characteristics. Chainsaws have a given load level; they are designed to operate in certain modes. For this reason, some tool owners are against the use of additional devices. This mainly applies to attachments for the Shtil, Husqvarna and other prestigious professional models.

The fact is that connecting the grinder attachment to a Partner or Husqvarna chainsaw does not go without leaving a trace. When using such devices, the tool engine operates at maximum speed. And this is done over a long period of time. In some cases, the saw does not have enough torque. As a result, the period between repairs is reduced, and internal parts wear out much faster.

On a note! According to research, attachments such as “Wood splitter”, “Winch”, “Corroder” and “Compressor” do not harm the technical condition of a gasoline saw.

The most unsafe types of attachments for chainsaws:

• "Bulgarian";
• "Mower";
• "Boat motor";
• "Boer".

When connecting the attachments, the chainsaw engine will operate at maximum speed.
If sanding equipment is used, the air intake filters on the tool become too clogged. The use of attachments such as “Pump” and “Boat Motor” requires long-term operation of the engine at high speeds, which is also not good for the chainsaw.

These disadvantages are fully or partially compensated for by the high wear resistance of modern chainsaws. The negative impact of the grinder attachment on the Husqvarna chainsaw can be reduced by using heat-resistant branded motor oil. It will protect the engine from premature wear.

Main types of chainsaw attachments: prices and characteristics of removable attachments

Removable attachments expand the functionality of the chainsaw, allowing you to use this tool not only for its intended purpose. You can find several dozen types of such devices on sale.

The most popular and in demand of them are:

• adapter attachments for longitudinal cutting of wood (vertically and horizontally);
• "Bark beetle" and "Koroder";
• “Water pump” and “Pump”;
• "Boer";
• "Boat motor";

At the moment, manufacturers offer a wide range of different attachments for chainsaws.

• "Trencher";
• "Wood splitter";
• "Bulgarian";
• "Trimmer" and "Mower";
• nozzles for cutting metal, etc.

Each of them has its own characteristics, characteristics and scope of application.

Motor drill - drill holes in the ground quickly and efficiently

If you need to drill holes in the ground in order to install posts in them, then you need to use a chainsaw attachment. Using a hand drill for such purposes requires significant physical effort, so a two-stroke motor from a chainsaw and an auger attachment will help make the work easier.

There are a lot of varieties of such set-top boxes, so when purchasing them, it is important to clarify for what purpose the device is needed. With their help you can drill not only soil, but also ice. Fishermen will appreciate this device, since drilling ice is much more difficult than drilling soil.

To install the attachment on the tool, you will need to remove from the chainsaw not only the chain with the bar, but also the drive sprocket with the clutch. The attachment comes complete with a special adapter coupling, which is installed on the shaft instead of the drive sprocket. If you think that an electric drill is better, then you are mistaken, because a gasoline engine is not only more powerful, but also mobile.

Chainsaw attachment for cutting metal, wood and stone: removable grinder

The grinder is one of the most popular attachments. In the household, it brings maximum benefits, as evidenced by numerous positive reviews on the Internet. Sometimes it is called an angle grinder attachment for a chainsaw, although it is not one, since it is intended solely for cutting material.

A universal attachment for a chainsaw for an angle grinder is secured to the body of the tool using studs, which are usually used to fix the saw bar. A V-belt drive acts as a connecting element between the drive shaft and the removable device. It is she who powers the nozzle.

For your home workshop, you can purchase an attachment for a Stihl 180 chainsaw. It is universal. This device can be connected to six different models of chainsaws from this company. The design is presented in three modifications, allowing the use of a circle measuring 18, 15 or 23 cm. Using this attachment you can process wood, stone and metal.

A removable grinder on a chainsaw for cutting is the most popular of the attachments.

The attachment is designed for the use of saws and abrasive discs, which significantly expands its scope of application. The owner of the tool will be able to efficiently perform such types of work as abrasive cutting of plastic, stone and metal. The price of the “Binder” attachment for a chainsaw of this model varies between 1900-2150 rubles.

On a note! Using the grinder attachment, you can carefully clean welding seams.

Grinder - when you have to cut thick metal

The grinder attachment for a chainsaw is a universal device, since on the shaft of such a device you can install not only abrasive discs for cutting metal, but also wheels with teeth for processing wood or diamond wheels if you need to cut ceramic tiles or stone.

The device is attached to the tool instead of a tire, and is driven by a V-belt drive. The diameter of the circle must be selected depending on the power of the tool itself, so the choice of such an attachment must be approached responsibly, otherwise the motor may jam during operation. Grinders and angle grinders heat up quickly when sawing thick metal, so to achieve the final result, you will need to take pauses so as not to burn out the electric motor. A chainsaw with an angle grinder-1 attachment will cope with such tasks not only quickly, but also effectively. The attachment can accommodate discs with a diameter of up to 20 cm, and the mounting hole is 22 mm.

This is interesting! Attachments for USHM-1 chainsaws are much cheaper than buying an angle grinder, so you need to think carefully before buying a grinder.

How to get the function of a trimmer and lawn mower: saw attachments for caring for your summer cottage

Using removable household accessories, a chainsaw can be turned into a convenient and useful tool for caring for lawns and ornamental shrubs in the courtyard of a private house or on a country site. For these purposes, attachments such as “Trimmer” and “Mower” are used.

A device designed for mowing a lawn is in many ways similar to a rotary mower. It has the same design and shape. This attachment is equipped with a sharp knife made of durable metal. It effectively cuts the grass on the lawn. On sale you can find branded attachments for Shtil and Husqvarna chainsaws. The purchase of devices of this type will cost on average 2200-2600 rubles. Such devices are rarely found in the assortment of other brands.

An attachment with a mower function for a chainsaw can be bought for 2.2-2.6 thousand rubles.

A gas trimmer attachment on a saw, also called a “bush trimmer,” is used to care for hedges. The capabilities of this removable device will also be useful if you need to clear the area of ​​young growth. The trimmer will not cope with small trees, but it can be used to remove branches.

A rotary trimmer is not as easy to operate as a household lawn mower. But thanks to its design, this device can effectively process lawns, leaving behind a fairly high-quality result. Moreover, work with its help is carried out in a very short time. The Trimmer attachment costs about 2,000 rubles.

We take a log and get boards from it!

Impeccably even cutting is obtained by using a leading ruler (a special guide is often used instead), which is usually called a straight template. It is, in fact, a small machine recommended for cases where woodworking is done more or less regularly. Such a miniature sawmill for longitudinal sawing costs from 10 thousand rubles. If you use it “once every hundred years”, it is better to do as described above.

Both the factory device and the DIY design cut logs according to the same pattern. Longitudinal cutting is carried out using a special chain. Finding her can be difficult. But there is a way out. Sawing trunks lengthwise can be done with a regular chain. You just need to carefully sharpen it at a 10-degree angle. Important point! The tool quickly loses its original sharpness during use. Therefore, it must be constantly sharpened so that cutting logs into boards does not cause difficulties, and the geometry of the resulting products meets the stated requirements.

Important Technical characteristics of the UAZ swamp vehicle and how to make an all-terrain vehicle with your own hands

Sawing logs into flat boards with a chainsaw equipped with a device is performed as follows:

1. 1. Take two straight and strong boards. Connect them at right angles to each other. The result is a reliable straight template.
2. 2. Make simple supports from wooden blocks. Use them to support the template you made.
3. 3. Place the barrel on the device.
4. 4. Fasten the frame to the tire, attach the supporting elements supporting the leading ruler to the ends of the log. The last operation requires horizontal installation. Use a building level for control.
5. 5. Secure all existing elements with self-tapping screws. Some craftsmen use nails for these purposes, which is undesirable. After cutting the logs into boards, you will have to remove the used fasteners. It will be difficult to do this without significant damage to the structure.
6. 6. Fix the template to the supports and adjust its height. Nuance. The cut will go somewhere 10 mm above the level of the ruler, and not strictly along it. Take this into account when adjusting the height.
7. 7. Rotate the log. Turn on the chainsaw. You make the first cut.

Then you need to free the log from the stops and boards, fix the template on the cut surface so that it faces in the direction of the second cut. The ruler can be attached with supports to the ends or directly to the surface of the barrel. Make a second cut. In relation to the first, it will be perpendicular.

Next, turn the log and fix it. The ruler can be removed. We will carry out further sawing without it - one of the cut sides of the trunk will serve as a guide. You need to adjust the thickness of the cut on the frame, saw off the log to get a beam with bark on only one side. Now turn the barrel again. Set up the frame. You carry out the final sawing and get the boards at your disposal. If their width is not important to you, there is no need to cut the trunk to fit the timber. Simply saw the workpiece to the middle, turn it 180°, then continue the operation you started.

Types of chainsaw attachments for rip cutting

For longitudinal sawing of wood, two types of attachments are used. Some of them are designed for cutting material in a vertical direction, while others - in a horizontal direction.

Attachments for cutting wood in the vertical direction consist of:

• from the adapter (attached in the base area on the tire);
• guide (used to transmit linear movement, fixed to a board that is placed on a log).

Devices for longitudinal sawing are available vertical and horizontal.
Thanks to this structure, the longitudinal cut is very precise. This type of attachment can be used for different purposes.

Using the vertical attachment, you can perform the following tasks:

• saw a log in two;
• divide the material into four parts;
• make high-quality timber from logs, which can subsequently be used for construction work;
• make boards or several small beams from logs.

On a note! If sawing involves making several beams, you will have to constantly change the position of the board during the process. Using a vertical attachment requires some skill, because the loose end of the guide can go to the side.

The horizontal nozzle, unlike the vertical one, is fixed on the guide in two places. The cost of removable devices for longitudinal cutting varies in the range from 1800 to 2300 rubles.

Longitudinal sawing device

Sometimes during the construction or repair of wooden structures, sawing of wood is required. It is expensive to purchase such equipment for home work, so you can assemble it yourself. A device for longitudinal sawing of logs with a chainsaw will help prepare a large number of boards and lumber.

Before you begin assembling the tool, you need to prepare drawings and carefully study them. The entire structure consists of a simple frame and guide. To ensure an even cut, the guide is fixed on both sides of the base. Manufacturing process:

1. The frame is made from a square pipe. Cross section - 20x20 mm. You can use a simple children's desk.
2. The size of the clamping part should be from 50 to 60 cm. It is positioned so that the end of each part forms the basis for the next mechanical unit (cross member). To ensure that the crossbar holds securely, it is welded to the structure.
3. To install the bolt ties, holes are made in the cross member with an electric drill. To secure the tire, a small protrusion is left at the center point of the cross member.
4. Such fastenings are installed in the upper part of the structure. In this case, the width of the bolt clamps must be greater than the height of the tire.
5. The supporting frame (10 cm wider than the length) is made rectangular. Holes for the nuts are made on both sides, 2 pieces of 10 cm each are attached perpendicularly. The nuts are welded to the support frame using a welding machine.
6. To facilitate longitudinal sawing of logs with a chainsaw, the structure is equipped with handles. To do this, a pre-bent metal part is welded to it.
7. Then all the finished parts of the structure are assembled together. To do this, clamps and a chainsaw bar are inserted into the groin parts. How wide the workpieces will be depends on the gap between the sidewall of the frame and the tire. Therefore, it is important to secure the chainsaw bar correctly.

To increase the speed and quality of sawing, a chain for longitudinal cutting of products is installed on a chainsaw for longitudinal sawing.

Useful features of the “Drill” attachment on a chainsaw

The "Bur" attachment is used in fish farms. It has a simple design, is quite easy to use and is used to supply air to frozen bodies of water. The combination of a gasoline saw and this attachment has repeatedly proven its success and efficiency in practice.

The "Drill" attachment is used for drilling holes in the ground or in ice.

The ice auger is lightweight and compact in size, which has made it so popular among ice fishing enthusiasts. At the same time, the nozzle is characterized by high productivity.

The MB-2 Ice drill is recognized as one of the best removable devices in this category. This attachment operates through a reduction gearbox, which reduces the rotational speed of the shaft to 150 rpm. You can find analogues of this device on sale, but this particular model requires a minimum of installation time. It takes about 5-10 minutes to connect the attachment to the chainsaw.

In addition, the “Bur” attachment is suitable for drilling wells in the ground. The diameter of the holes reaches 35-40 cm. Such a device can greatly facilitate construction and installation work. Depending on the functionality, the price of a nozzle for drilling ice or soil can range from 2,500 to 5,500 rubles.

Features of chainsaw attachments “Bark beetle” and “Koroder”

The bark beetle attachment is a milling head. It is used for processing beams, logs and boards. This removable tool allows you to quickly and accurately cut a cup or groove in wood. This attachment can also be used for rough sanding of material.

The bark beetle attachment is used for processing beams and boards, as well as for rough grinding.

The bark beetle is a mounted type of equipment and is equipped with a special belt. It's easy to use. Moreover, the removable device works quickly and efficiently. The special structure allows the bark beetle to be used as an attachment for the Husqvarna, Shtil chainsaw and many other tool options. The device is compatible with almost any model. The cost of “Bark Beetle” is approximately 1600-2000 rubles.

On a note! The bark beetle attachment is compatible only with those chainsaw models that are equipped with a six-point sprocket.

The “Coroder” (“Debarker”) chainsaw attachment has a wide range of applications, but most often it is used to remove branches and excess wood from logs. Using this device, you can turn a flat bar into a rounded product.

The Coroder attachment comes in two types:

1. Disk.
2. Drum.

Drum attachments are designed to remove excess bark from the surface of a tree. The working body consists of a drum and a cutter. The removable device is installed on the bearing assembly. Despite its simple design, the drum corder is highly reliable. If you strictly follow the instructions, such an attachment can be installed on a chainsaw within 2 minutes.

The Corroder is suitable for removing twigs and branches, as well as excess bark.

Disc nozzles are designed to form grooves and recesses of varying complexity, depth and size. The “koroder” in this case is driven by a V-belt. In this case, the user can independently adjust the rotational speed of the working part of the nozzle.

The removable bark attachment is not only suitable for effectively and quickly removing bark from a tree trunk, it can also be used to plane logs. It will take no more than 5 minutes to install the device on a gasoline saw. The capabilities of the Debarker attachment are indispensable in the construction of log houses. It is also worth noting that the nozzle body has an additional protection system, so the operation of the device is completely safe. Buying a nozzle will cost approximately 15,000-18,000 rubles.

Debarker is a universal device for cleaning logs from bark and knots

Debarkers are those attachments that are used to clean logs from bark, growths and knots, as well as to make longitudinal and transverse grooves in the wood. Debarkers differ in design, as they are of drum and disk type. Drum units are used for removing bark and are also called debarkers, and disc units are used for cutting mounting grooves, bowls and recesses.

The working part of the device includes a drum or cutter, which are mounted in a bearing unit. The debarker is driven by a belt drive. The rotation speed of the working part is adjusted due to the diameter of the pulley used and the force of pressing the accelerator handle. The larger the pulley diameter, the higher the debarker rotation speed.

This is interesting! If you work with wood, then an attachment such as a debarker will be indispensable when clearing sawn logs of bark or when cutting out mounting grooves and cups.

Characteristics of the “Wood splitter” attachment for a chainsaw

It is very difficult to split thick logs and stumps using an ordinary ax. This process is long and laborious. To make this task easier, it is enough to purchase and install a “Wood Splitter” attachment on the saw. It has a cone-shaped, pointed shape, due to which the wood splits during the screwing process.

Such attachments are most often universal and suitable for different models of chainsaws. According to reviews from users on the network, the “Wood Splitter” greatly simplifies the process of splitting stumps and logs, saving time and effort. To confirm this, you can consider the possibilities of the Partner chainsaw attachment.

The Wood Splitter attachment is universal and fits most models of chainsaws.

This wood splitter copes with logs with a diameter of 40 cm (although more powerful models of attachments can be found on sale). It is suitable for splitting material directly on the ground, so it can be used for splitting long firewood, old boards, and slabs. The average cost of such a nozzle is 6,300 rubles.

On a note! It is not recommended to use a removable angle grinder and other accessories as an attachment on a Champion chainsaw, the power of which does not exceed 2 kW. This requirement also applies to other companies that produce low-power models of this tool.

Winch - for lifting and moving loads

If the farm has a winch, but there is no drive to it, then a motor from a chainsaw will replace it. The store also has ready-made winches for connecting to chainsaws. The capabilities of an electric winch are not as high as those of a motorized device.

The attachment is attached to the shaft of the unit, after which it can be used for loading and unloading heavy loads, as well as pulling stuck cars out of mud captivity. The winch is a universal device with which any heavy operations are performed with ease and high speed.

This is interesting! Using a winch, you can lift a load weighing up to 500 kg. This is quite enough for loading heavy loads into a car trailer.

In addition to those attachments that were described in detail in the material, you can connect a wood splitter to a chainsaw to split sawn stumps. The wood splitter has a cylindrical shape with a pointed point, which makes it possible for the nozzle to enter inside the wood, and upon reaching a certain recess, the hemp is split. This attachment eliminates the need to work with an axe.

If buying a chainsaw attachment is considered a luxury, then you can make any attachment yourself. To do this, you will need old tools, for example, to make a pump, you can take an old pump and weld an attachment for a chainsaw from it. It doesn’t matter what brand your chainsaw is Shtil, Husqvarna, Makita or Partner. All attachments are universal, and you can be sure of this when purchasing. By purchasing an attachment, you not only simplify your work, but also save a lot of money, because purchasing electric tools will cost 3-4 times more.

Pumping equipment: pump attachment for a chainsaw

The removable pump for a gasoline saw works on the same principle as a standard centrifugal pump. The structure of the structure is very simple, so there are no problems with installing the equipment and it does not require much time.

The pump is a turbine that is driven in two ways: using the drive sprocket shaft (directly) or from a pulley. A turbine usually has several blades. After the nozzle is installed, you need to connect two hoses to it. One of them will be a supply, and the second is intended to drain liquid. Hoses are not included and will have to be purchased separately.

The pump attachment for the chainsaw is simple and easy to use.

Using the “Pump” attachment on a chainsaw, you can perform the following tasks:

• drain a flooded basement or cellar;
• pump water from a well or well;
• fill the container with water for irrigation;
• move water from one place to another.

The pump can benefit not only owners of large and small farms. This device is also used in ship docks.

Like any other attachments for a gasoline saw, pumping equipment is produced by several companies, so the level of performance and other characteristics of devices from different companies may differ. Most models have a capacity of approximately 5 l/h.

The main advantages of a removable pump include its mobility. If desired, you can make this attachment yourself at home. This will require skills in working with a welding machine. On the other hand, factory-made pumps are made of plastic, which reduces their cost, and therefore such a device is much easier to buy than to create with your own hands. The average price is 3,000 rubles.

You can buy a pump attachment for a chainsaw for an average of 3 thousand rubles.

On a note! The performance of the removable pump depends on the size of the impeller. If it is expected that the pump will be used to perform large volumes of work, it is advisable to purchase a nozzle of appropriate dimensions.

Dependence of pitch on additional characteristics of saw chains

Comparative table of characteristics of electric chain saws.

During the movement of the chain and cutting wood, very high loads are applied to it; therefore, an important characteristic is the thickness of the link element that fits into the groove of the bar and slides in it. This value also shows the thickness of the fastening elements of the links

You can measure it with a regular caliper.

Typical guide element thicknesses:

• 1.1 mm;
• 1.3 mm;
• 1.5 mm;
• 1.6 mm;
• 2.0 mm.

Thicknesses of 1.1 and 1.3 mm are used for the manufacture of entry-level chains intended for minor work. Most often, the step length at these values ​​is 0.325”, which implies a gentle regime and low loads.

The value of 1.5 mm is the most common on the market of chainsaws and accessories; this value is enough to ensure safe operation at a pitch of 3/8”. However, this value will always indicate that the chain is not intended for professional activities.

The guides, which have thicknesses of 1.6 and 2.0”, are designed to carry out the most complex work, that is, they allow the use of equipment in shifts. At the same time, you need to know that these two values ​​are a certain classifier, indicating that the metal for the manufacture of these chains is smelted from special grades of steel, that is, increased strength is built into the structure.

All produced chains may differ in cutting depth. It is characterized by the height of the cutting tooth (profile). The height is measured between the top flange of the cutting edge and the stop (all on one segment). There are low profile and high profile chain products.

Chain pitch (a/2) and shank thickness (b).

The higher the profile, the higher the entry into the wood and, accordingly, the cutting speed. The height of the profile affects the occurrence of vibrations, which can cause increased wear of the drive or difficulty holding the tool in the hands; the higher the cutting part, the stronger the vibrations will be. Also, a high-profile chain requires increased engine power.

Household chainsaws always have a low profile chain. Professional devices combine different options, but always adhere to the fact that if the chain has a large pitch, then its profile is low, and if the pitch is 0.325, the profile is high.

Such variations create the opportunity to increase the cutting speed not by increments, but by the profile height (cut depth). However, most professional tools for felling trees focus on increasing the pitch rather than the profile height, arguing that the chainsaw is more controllable in this version.

How can a “Boat Motor” attachment on a chainsaw replace an engine?

“Boat motor” is an attachment that is used as a replacement for a gasoline engine. It will be the best option for those cases when there is no need for high speed movement through water. This removable equipment will help you get from one place to another.

This device consists of several components:

• tubes with transmission (the movement is transmitted from the shaft of the gasoline saw to the screw of the nozzle);
• screw;
• fastenings for fixing the device on the boat.

To install a boat attachment on a chainsaw, you need to follow a few simple steps. To begin, the drive sprocket is removed. This is done together with the clutch. After this, a removable attachment and gearbox are installed on the chainsaw shaft. This type of equipment can be installed on displacement and planing boats. The main thing is that the height of their transom does not exceed 38 cm.

The “Boat Motor” attachment can be used in cases where high speed of movement through the water is not needed.

The propeller usually has two or three blades. Depending on the engine power, such a boat can reach speeds of up to 15-20 km/h, with one adult passenger and his cargo on board. This is quite enough to move along a calm river or lake. In this case, the engine consumes about 1 liter of fuel per hour.

The “Boat Motor” attachment is compact, lightweight (no more than 5 kg) and easily fits in the trunk of a car. That is why it is in such great demand among fishermen. The approximate cost of the “Boat Motor” is 1200-2200 rubles.

With the help of this and many other attachments, you can significantly simplify and speed up repair, installation and construction work on the site, while saving on the purchase of additional tools. Removable devices open up wide opportunities for housekeeping, as well as for creativity. The most important thing is not to overload the chainsaw engine. This is especially true in cases where not factory-made, but home-made equipment is used. Otherwise, the risk of injury increases.

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:

1. Great power. If we compare a homemade nozzle with factory models, then its power is 2 times greater.
2. Independence. The tool does not require electricity, so it can be used anywhere.
3. Easy assembly. All the necessary tools and materials can be purchased at the store or searched on your farm.
4. 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.
