Attachments and accessories for chainsaws. Stihl saw chains Main types of links

The Shtil company produces not only chainsaws and brush cutters, but also consumables for them. In this article we will talk about Stihl saw chains, their types, markings, characteristics, and compare them with competitors.

All Stihl chains are marked, thanks to which they can be identified and determined for which models of chainsaws and types of work they are intended.

The name of the chain model must indicate its length (number of links), pitch and width. The type is also indicated. Type is an internal brand designation, thanks to which company specialists can determine the type and shape of the cutting tooth, the dimensions of the link and connecting elements. The designation can be complete, or it can be abbreviated in capital letters, for example, the Picco Micro 3 chain, abbreviated as PM3.

The average user, in principle, does not need such information, because in order to choose the right headset, it is enough to know the characteristics of the chainsaw, the planned volume and types of work.

For ease of selection, the Shtil company website has an electronic consultant that automatically generates a list of chains suitable for a specific chainsaw model.

The service is convenient and understandable, but it has one big drawback: you can select chains only for. If you have a different chainsaw, then you will have to search by characteristics and name, which is not very convenient, since the list of models is quite large.

Below we suggest watching a short but interesting and educational video video about Stihl chains, their production process and quality control.

Now let's consider specific models Shtil chains, their markings, characteristics and purpose.

Picco Micro (PM)

Stihl chain with a low profile, recommended by the manufacturer for use on lightweight chainsaws and loppers. The peculiarity of the chain is a soft cut, with reduced kickback. It has four versions, which differ in the number of links. This:

3/8″ P Picco Micro (PM), 1.3 mm (50);
3/8″ P Picco Micro (PM), 1.3 mm (51);
3/8″ P Picco Micro (PM), 1.3 mm (55);
3/8″ P Picco Micro (PM), 1.3 mm (56).

This chain can be used on Shtil MS chainsaws, etc. etc. Recommended retail price from 490 to 550 rubles. The specific price depends on the number of links. Also, the Stihl saw chain can be sold in coils of 50 and 100 meters, and can be riveted using a Shtil riveting machine or similar. Information on how to rivet correctly can be found on our website.

3/8″ P Picco Micro Mini 3 (PMM3), 1.1 mm

Distinctive feature– the narrowest possible cut. Abbreviated designation PMM3. It is recommended for entry-level chainsaws, as well as hedge trimmers and hedge trimmers. Has three versions:

3/8″ P Picco Micro Mini 3 (PMM3), 1.1 mm (39);
3/8″ P Picco Micro Mini 3 (PMM3), 1.1 mm (44);
3/8″ P Picco Micro Mini 3 (PMM3), 1.1 mm (50).

Can be used on chainsaws Shtil MS, 180, . It belongs to the comfort class, because it has minimal vibration and recoil.

Important: a chain with a width of 1.1 mm must be used with a corresponding bar, otherwise it will dangle in the mounting socket, which will lead to rapid wear of both the headset itself and the guide bar.

1/4″ P Picco Micro 3 (PM3), 1.1 mm

Recommended especially for pole saws and compact chainsaws, for example, MS 150 TC-E or MS 193 T. It is considered exclusive because it has a non-standard 1/4″ pitch, narrow and flat design. It has three versions, the length of which is 56, 64 or 72 links.

3/8″ P Picco Micro 3 (PM3), 1.3 mm

This model belongs to the comfort class and is intended for professional use on light and compact chainsaws. The chain offers high performance, comparable to standard performance, while reducing recoil thanks to its low profile. There are several options:

3/8″ P Picco Micro 3 (PM3), 1.3 mm, 50 links;
3/8″ P Picco Micro 3 (PM3), 1.3 mm (51);
3/8″ P Picco Micro 3 (PM3), 1.3 mm (55);
3/8″ P Picco Micro 3 (PM3), 1.3 mm (56).

3/8″ P Picco Super (PS), 1.3 mm

Picco Super, according to the manufacturer, is the world's first chain that has a chisel tooth. Developed by Shtil specifically for forestry professionals. Easy cutting, comfortable level of vibration and smooth running. It has a clean cutting surface, which is important for those who carve wood with a chainsaw. Execution options:

3/8" P Picco Super, 1.3mm (44);
3/8" P Picco Super, 1.3mm (50);
3/8" P Picco Super, 1.3mm (55).

Can be used with both professional, semi-professional and household chainsaw models.

1/4″ Rapid Micro Spezial (RMS), 1.3 mm

Designed specifically for shaped wood cutting. A distinctive feature is the shortened upper edge of the tooth, thanks to which there is no need to put pressure on the saw in order for the chain to cut into the wood. It is characterized by high speed and smoothness when performing curved cuts compared to conventional chains that have a similar 1/4″ pitch. Available in two versions:

1/4 Rapid Micro Spezial, 1.3 mm(56);
1/4 Rapid Micro Special, 1.3 mm(64).

Rapid Micro chain series

The Rapid Micro chain line includes about 10 types, each of which has an average of three designs with different pitch and width characteristics. Rapid Micro series chains combine tooth shape and steel quality. They are recommended for use on Shtil chainsaws operating in agriculture(semi-professional). Short designation RM.

Rapid Super (RS) range

This line is designed for professionals. Of course, no one forbids the use of such chains on household models chainsaws, but their cost is slightly higher than conventional chains; for example, Picco Micro 3 will cost much less.

According to the manufacturer, Rapid Super is capable of long time work without sharpening and their productivity is not just high, but extremely high. This headset easily copes with heavily contaminated or frozen wood. If you look at the design options, it becomes clear that this chain is definitely not for light and compact chainsaws. Maximum size, released for sale - 105 links, this is almost twice as long as the chain on Shtil MS 180.

Rapid Duro 3 (RD3), 1.6 mm

This line of Stihl chains has an increased service life due to the use of special hard alloys in them. Intended for use in agriculture, i.e. recommended for semi-professional Shtil models. There are quite a lot of options. Rapid Duro 3 (RD3), 1.6mm can be had in 0.325, 3/8 or 0.404 inch pitches. The most expensive chain in this line costs about 2,500 rubles. and has a length of 66 links.

3/8″ Rapid Duro Rescue (RDR), 1.6 mm

This is a special Stihl chain for emergency work, in our country it received the nickname “Supertooth”. Due to pobedite soldering on the cutting edge of the tooth, it can cut wood with nails, glass, brick and others. Construction Materials. Where there is maximum difficult conditions and a regular chain will be helpless, Rapid Duro Rescue (RDR) will do everything as quickly as possible.

It has a length of 72 teeth, is not available in other versions, and is recommended for use on saws for rescue work, for example, Shtil MS 461 R with a power of 4.4 kW. Manufacturer's recommended price for Rapid Duro starts from RUB 9,060.

All prices that we announced in the article were taken from the company’s official website.

We invite you to watch a video showing a comparative test of Stihl saw chains. The video is in English, but it shows that a concrete insert is poured into the tree trunk on which the cutting speed test is being carried out. A regular headset cannot handle even three cuts, while a special one makes more than 10 cuts and remains operational.

Which chain to use for rip sawing

Chainsaw users often receive a question: which chain is suitable for rip sawing and are there any chains specifically designed for this purpose?

At the moment, there are no chains specially designed for sawing a tree trunk lengthwise, and most likely there will not be any, since any saw chain can be used for these purposes. The difference between a regular headset and a longitudinal one is the sharpening angle.

Using a straightening machine, you can make a special one from a regular set - one that facilitates longitudinal cutting. You can find information on exactly how this is done on our website.

Which chain is better Stihl or Oregon

It is quite difficult to choose which chain is better, Shtil or Oregon, because they are almost the same in quality. The Oregon company, like Shtil, specializes in their production and invests in development, constantly improving and releasing new models.

If you compare at the user level, the Oregon is a little softer, they dull faster, but they are lighter. Shtilevsky ones are almost all hardened, the metal is difficult to sharpen, but holds an edge a little longer.

Interesting. According to experts, the issue of headset quality is relative. Many users first use used motor oil for lubrication, and then say that this or that model and brand of chain is of poor quality, although the reason for premature wear lies in metal shavings, which are contained in any used oil, even that which has had time to settle before filling.

Reasons for rupture of the saw set

Sometimes, while using a chainsaw, the headset may break. This phenomenon is not common, but occurs from time to time. There may be several reasons, the first and most common is severe wear and tear. During operation, the edges rub against the bar, as a result the metal gradually wears off and the chain, unable to withstand the load, breaks.

Important! The use of high-quality adhesive oils can significantly extend the life of the saw set.

The second reason is the untimely replacement of the drive sprocket and saw bar or their replacement separately. According to the recommendations given by manufacturers, the saw set, bar and drive sprocket should be replaced as a set. This will prevent wear, stretching and tearing as a result of increased loads.

Third, this is marriage. The machine disk rotates at high speeds, and if the groove depth is set incorrectly or for some reason the working stroke of the machine increases, then a split second will be enough to trim the edges of the connecting links. If after sharpening you do not check its quality and the presence of cut links, then during work under load, the cut link may break.

The fourth and last one is a defect in the rivets. Common cause Breaking a chain is caused by improper connection or reuse of connecting links. If your cutting set is torn, then this information will be very useful.

Stihl sharpening machine

In conclusion, a little about grinding machine Calm. Today, the USG machine is presented on the company's official website. Sharpening on the machine works automatically, and feeding is done manually. The machine is capable of sharpening not only the cutting edge of the working tooth, but also the depth limiter, which is impossible to do on similar competing machines. For more information about the Shtil sharpening machine and its operation, watch the video.

Conclusion

The Shtil company produces high-quality chains for its chainsaws and pole saws, which are popular among both professionals and ordinary users. If we compare Stihl chains with competitors, they are a little stronger, but more difficult to bend manual sharpening, which is not very good for ordinary users, because for sharpening you have to contact a service center.

It is not difficult to find a device for a chainsaw for longitudinal sawing on the modern market; you can do it yourself. What type you will need in your work depends on the location of the cut (can be horizontal or vertical), diameter wood material which you will process, the level of ease of use and cutting accuracy.

Device for longitudinal cutting of logs

Longitudinal sawing of logs is carried out using a special device. It consists of the following components:

an adapter that is fixed on the tire in the base area;
guide, the main task which consists in transmitting linear motion to the main component.

The last component was attached to the board on the log that the operator was going to saw.

This kind of device, as we have already found out, having examined it design features, guarantees straight-line movement of the guide bar, which ensures the accuracy of the longitudinal cut.

This device allows you to:

sawing a log into two parts;
sawing material into quarters;
cut a beam from a log that will be used for construction work(it will look neat, so the masonry slopes look good);
split the logs into several beams or boards.

Please note that if you have set yourself the task of cutting into logs and beams, you will have to change the position of the board many times. In addition, good dexterity is useful for precise cutting. At first, the loose end of the guide bar will move sideways. This will not allow achieving consistency of performance and exact parallelism of each side of the board or beams.

A device similar in design can be used to cut material in a horizontal position if necessary. If you carry out comparative characteristics, then the device for cutting vertically makes it possible to obtain wooden elements of equal thickness at the output, which makes it possible to characterize this attachment as accurate and functional.

Second adaptation option

The main design features of this device:

fixed on the guide of the saw set not in one place, but in two, at the tip, as well as at the beginning (the structural type is frame, which ensures maximum strength);
the fastening area can shift, it all depends on your needs along the guide, which makes it possible to set the desired width relative to the size of the log;
the component (guide) of the device can be located at any distance in relation to the tire, which also allows you to focus your work on the required dimensions of boards and beams (primarily thickness).

How to work with such a device? Simply and easily:

We make the first cut in a horizontal plane using a guide, a structural part of the frame installed on the log;
the second and further cuts are made, focusing on the other main surface, which usually serves Smooth surface previous move.

Important! To prevent the saw from becoming jammed during operation of the power unit and the device for longitudinal cutting, spacers are inserted into the cut to prevent the sawed area from narrowing.

What to do if the operator needs to cut a log whose diameter is larger than the saw guide installed on the tool? Then you need a complex chainsaw attachment for longitudinal cutting. Please note that in this case, even the rated engine speed will not allow the lubrication system to release enough oil to ensure that the entire chain is lubricated evenly.

To improve the quality of lubrication and avoid rapid wear of the bar, sprocket and saw element, to the end of the guide from additional system(can be made from a hose and a reservoir) supply more consumables. To ensure that the oil is supplied by gravity, the reservoir is mounted at an elevation relative to the guide.

Universal device for longitudinal spreading

The universal device Big Mill allows you to accurately cut logs, even those whose diameter reaches 500 millimeters. In this case, the exact thickness of the boards can be set based on a special ruler, which the operator will find on the device stand (applied directly to it). Many craftsmen create their own devices, focusing on the model of this type of universal attachment.

How to unravel a log lengthwise using a universal device? Follow this algorithm of actions.

We take a couple of even boards, connect them, forming a T-shaped structure with an angle of 90 degrees. This design will act as a ruler, allowing the tool to move smoothly. In this case, the docks need to be twisted like this (taking into account the dimensions of the device for longitudinal dissolution) so that the power unit does not touch the ruler (it should be placed at a distance of 10 millimeters above).
Creates a pair of stops, which are ready-made from two parts (L-shaped). These components will prevent the log from rotating when it is cut. For reliability, the boards are secured with metal corners.
Rolls the log onto the stops (it is easier to roll those whose diameter is relatively small). If necessary installation big log on the stops you will need to turn to someone for help.
We connect the ends of the log and the stops using self-tapping screws (take those that are longer than the rest). You should not use nails, since the second longitudinal cut will require you to rebuild the entire structure.
The T-shaped structure, which acts as a ruler, is attached to the stops with clamps.
The ruler is connected to a chainsaw, on which a universal device has already been installed.
Now we adjust the thickness of the boards that you want to get in the end. Don't forget when setting up this parameter, about the thickness of the saw and the gap between the T-shaped structure and the blade (10 millimeters).
We turn the material for cutting away from ourselves by 30 (this will make cutting longitudinally much easier).
We make a cut lengthwise.
He removes the ruler, unscrews the clamps, and removes the stops at the ends.
We place the T-shaped structure on the plane that we got after the first cut, secure the guide element with self-tapping screws.
We fix the log as securely as possible in order to make an accurate second cut in the horizontal plane. It will run perpendicular to the first cut.

This method can be used for the third and fourth cuts (each time, re-setting the ruler) to obtain a square loaf at the end.

If your task is to saw a log into boards, then after the second horizontal cut we no longer use a ruler, performing all manipulations only with universal device. We will use one plane as a guide. As a result, the operator will receive a semi-edged board.

Craftsmen know that any profile that has such characteristics as:

high structural rigidity;
light weight.

Available materials that meet such requirements are aluminum and duralumin. The best option is a device made from levels (aluminum) and plaster rules (this element served as a guide). The plaster rules are aluminum parts, although you can safely use another lightweight profile down to the boards and stairs (it’s good if it’s also aluminum). An alternative, of course, can be an iron element, but then the nozzle will be heavy and inconvenient to use (it will cause a lot of inconvenience during prolonged use).

Taking into account the friction force during operation of the power unit, care must be taken to increase the productivity of the tool. To do this, it is recommended to use aluminum rollers to serve as your base. Another a good option– use of plastic (the main thing is that it is elastic), which must be fixed to the base of the nozzle with bolts.

Now almost everyone has a chainsaw, but many use it only for its intended purpose. Harvesting firewood, pruning branches, all these works are performed, as a rule, no more than once a year; the rest of the time the chainsaw gathers dust on the garage shelf, but this is not correct. A chainsaw can be used as a power unit for various devices, this will be discussed in this article.

There are special attachments for chainsaws on sale, with the help of which the functionality of the tool is significantly increased.

Using additional equipment from a chainsaw, you can make a wood splitter; it will help you cope with logs that are difficult to split with an ax, or a boat motor, for trips on a rubber boat.

Essentially, attachments are necessary to get the most out of your chainsaw so that it doesn't sit on the shelf gathering dust, but is used every day to solve a wide variety of tasks.

No special education or skills are required to install the attachments; everything is simple and easy.

What attachments are there for chainsaws?

Today, a large selection of chainsaw attachments have been developed by manufacturers and are commercially available. More specifically, for your saw you can buy:

Boat motor attachment.
Winch.
Pump.
Motor drill.
Wood splitter
Device for cutting boards.

If you like to make things with your own hands, then the saw will be an excellent assistant, because it can be used as a power unit for your inventions. For example, the video below shows how you can make a go-kart for your child from a simple chainsaw. It's very interesting and not as difficult as it seems.

And the next video shows homemade snow blower, the engine of which is a chainsaw. The idea is very good, but the snow blower is a little unfinished, but it is still able to make cleaning the territory of a private house easier.

Now let’s look at each of the attachments in more detail, look at the pros and cons of use, and draw a conclusion about how the use of the attachment affects the life of the chainsaw and its performance.

boat motor

The nozzle is designed for installation on small rubber boats having a transom. Characteristics:

Gear ratio 1:2.
Maximum speed in still water is 20 km/h.
Three-blade propeller with a diameter of 150 mm.
Fuel consumption is 1 liter per hour.
Weight when assembled is 8 kg.

Such characteristics allow the nozzle to be used by those who do not need high speed movement through the water, but simply need to get from point “A” to point “B”. It is popular among fishermen because it is light and compact and fits into the trunk of a passenger car.

All necessary fasteners are supplied with the nozzle. There are instructions for installing the nozzle and its proper use.

The main advantage of using such an attachment for a chainsaw is saving on the purchase of a boat motor.

You can learn how to install a chainsaw on a boat motor attachment by watching the video.

Winch

Another useful attachment for a chainsaw is a winch. It can be used to lift loads weighing up to one and a half tons. Conventional electric winch, requires a electric current, which significantly reduces its capabilities. A chainsaw with a winch can be used anywhere.

Having such an attachment on a firewood harvesting site, you can load tree trunks, cross-cut into several logs. Also, if necessary, such an attachment will allow you to pull out a stuck passenger car; it is not suitable for trucks.

The cost of a winch for a chainsaw is a little more expensive than an electric one, but its mobility and ease of use make up for the difference.

There are several models of chainsaw winches on sale, which may differ in cable length, size and weight. On average, the length of the cable is about 30 meters, weight no more than 12 kg.

This is interesting: using a plow together with a chainsaw winch, you can process land plot, while spending a minimum of effort.

How to plow the ground with a chainsaw and winch is shown in the video. The advantages of this method are that in this way it is possible to cultivate the land on suburban areas where there is no possibility of connecting to electricity.

water pump

A special attachment called a chainsaw pump will help pump out water from a flooded cellar, pump up a water tank for irrigation from a well, or simply pump water from one place to another.

The device is quite simple and does not require special skills to install on the saw. Its advantage is mobility and connection speed. In addition to the nozzle, you will need to purchase hoses. Pumps, like other saw attachments, are produced by several manufacturers, so they can have different performance and other characteristics.

This attachment is universal and can be installed on chainsaws of various models and brands. For those who are not used to paying for additional equipment for a chainsaw, you can make a pump yourself.

Motor drill

Another useful attachment in everyday life is a motorized auger (ice auger). There are a lot of options for this console, including homemade ones. It can be useful not only for fans of winter fishing, because it can be used to drill holes for installing fence posts.

The advantage over electric options is mobility, since the drill can be used regardless of the availability of electricity.

Important! To install the drill attachment, you will need to remove the standard clutch and drive sprocket from the chainsaw, for which you need to lock the crankshaft. You can find information on how to properly remove the clutch from a chainsaw on our website.

An adapter coupling is supplied with the saw drill, which is installed instead of the drive sprocket.

Wood splitter

Thick lumps are difficult to split with an ax; to make the process easier, you can install a wood splitter attachment on a chainsaw. It is screwed into the block and, due to its cone-shaped shape, splits it.

The attachment is universal and can work on various models of chainsaws. User reviews about this device are positive, because it really facilitates the process of splitting large lumps.

The cost of the wood splitter attachment is reasonable, currently it does not exceed 1000 rubles. You can buy it on specialized websites or in petrol stores. Installation of this gadget does not require any specific skills; the manufacturers provide instructions.

Jointer

If you need to plan a large number of boards, but you do not have a specialized machine, then the jointer attachment will help you do this.

The attachment is mounted on standard bolts for fastening the tire; instead of the clutch, a drive pulley is installed on which the belt is put. Through the belt, a force is transmitted from the drive pulley to the driven pulley, which causes the planing shaft with two knives to rotate.

The system is very simple and reliable; the quality of processing depends on the maximum number of revolutions of the chainsaw on which it is installed.

In order to compensate for the lack of load on the engine when using the jointer attachment, you can slightly reduce maximum amount rpm You can find instructions for adjusting the carburetor of a chainsaw on our website.

The attachment is not universal; for it to work, you need to replace the drive sprocket with a pulley; the mounts are different for all chainsaws. Therefore, when purchasing, you need to consult and choose a model of attachment suitable for your chainsaw.

Bark beetle

Another attachment for a chainsaw, which is designed for cleaning tree trunks from bark.

It is very similar to a jointer, is attached in a similar way and has two pulleys and a belt. The main difference is that the bark beetle does not have a stop bar that prevents the knives from going deep, as a result of which they only remove a certain amount of chips.

Bulgarian

One of the most popular attachments, about which users leave only positive reviews, is an angle grinder, or it is also called an angle grinder, but it is not one, because it is intended only for cutting.

Attaches to the standard place of the tire. Not universal, it is selected for the model of chainsaw for which it is intended. Not expensive and easy to use. Consists of the following elements:

drive pulley;
frames;
driven pulley with shaft and disk mount;
force transmitting belt;
protection.

The simplicity of the design and standard grinder consumables (discs) made this attachment very popular. Its advantage is mobility, the ability to be used in places where there is no electricity.

In place of the cutting disc for metal, which is shown in the photo, you can install carbide ones for cutting concrete and use a saw with an attachment as a wall chaser.

Advice. When working with an angle grinder attachment, the engine experiences significant load, so it is not recommended for chainsaws with a power of less than 2 kW.

The following video shows how to assemble, install, configure and operate the attachment. The video shows that the 1.5 kW chainsaw cannot cope with the load, and there is a noticeable drop in speed. To prevent this from happening again, use more powerful saws.

Attachments for Shtil and Husqvarna chainsaws

There is no special attachment that would be suitable only for the Shtil chainsaw and would have any unique functionality that others do not have. Everything that can be installed on Shtil saws has analogues for other chainsaws, the same with Husqvarna chainsaws. For this reason, when choosing a chainsaw, you should not pay attention to the advice of sellers regarding the purchase of a specific model, due to the possibility of installing additional equipment on it that expands the functionality.

The only thing you should pay attention to when choosing is power, because to work with attachments it is recommended to have a more powerful chainsaw.

What devices can you make with your own hands?

Many “garage” craftsmen do not spend money on buying chainsaw attachments, but make them themselves. In fact, there is nothing complicated about them and almost everything can be made with your own hands. All you need for this is a welding machine, sandpaper and the necessary knowledge and experience; spare parts from old tools and mechanisms, for example: chains, belts, pulleys, shafts, etc., can also be useful.

On the Internet you can find information on how to make an angle grinder attachment, a pump, a winch or a drill. In order to dispel doubts, we suggest watching a video that shows a homemade attachment for a Shtil chainsaw made from an old fishing drill.

Device for cutting boards

In conclusion of the article, I would like to mention such a device as a stand for cutting boards using a chainsaw. Essentially, this is a mini sawmill that you can assemble on your own site, install a chainsaw in it and cut tree trunks into boards.

There are quite a lot of options for sawmills made from chainsaws, some are factory-made, like LOGOSOL, and some are home-made. We invite you to watch a video about the operation of a homemade, budget sawmill using a chainsaw.

Conclusion

A chainsaw is capable of not only performing transverse or longitudinal cuts of wood, it allows creativity and invention based on many tools and devices that are useful in the household, making everyday work easier or even relaxing for your own pleasure.

Remember that when using homemade nozzles for a chainsaw, you should be careful and not overload its engine, you should also not forget about safety precautions, since all responsibility in case of injury lies with you.

A chainsaw is a tool that is designed for collecting firewood and should be in every household. A special attachment for a chainsaw will help increase the potential of the tool. If you add special attachments to the device, it will turn into a boat motor, a wood splitter and much more.

Longitudinal sawing device

Sometimes during construction or renovation wooden structures wood cutting 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:

From square pipe make the frame. Cross section - 20x20 mm. You can use a simple children's desk.
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.
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.
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.
The supporting frame (10 cm wider than the length) is made rectangular. Holes for nuts are made on both sides, and 2 pieces of 10 cm each are attached perpendicularly. Welding machine the nuts are welded to the support frame.
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.
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.

Other devices

There is a wide range of accessories for chainsaws in the store. Devices have their own advantages and disadvantages, which have different effects on the performance of the device. In order not to spend money on purchasing them, you can make a device from chainsaw accessories with your own hands. For inventors who like to make things at home, such a tool will become an indispensable assistant.
