Saw attachment for longitudinal cutting. A device for cutting logs into planks with a chainsaw. Sawing logs into boards using a chainsaw

Since ancient times, wood has been the most in demand building material. And if earlier rather primitive tools were used for its processing, today the latest modern technology is used. So, for example, in order to cut wood and process it to required sizes, builders resort to the help of a sawmill. Unfortunately, such a tool is not cheap and therefore not available to everyone. Home craftsmen found a way out of this situation by making a sawmill from a chainsaw with their own hands. Tips for its design, drawings and video instructions can be found on numerous Internet sites, as well as in our article.

Types and features of chainsaw sawmills

Construction markets offer a large selection of sawmills, which are based on a chainsaw. Fixed in a trolley with rollers, the unit can be manually moved along a pre-laid rail track. A powerful chainsaw or band saw can be used to harvest wood.

For living conditions Large sawmills are most often not required, so the optimal solution would be to make a functional homemade mini-machine. Such a unit will have small sizes, and therefore can be easily moved if necessary.

More often as the main element similar device chainsaw protrudes, which can be purchased at a specialized store or use a Ural brand unit.

Do-it-yourself sawmill from a chainsaw: video instructions and drawings

Having the drawings available and having studied the video instructions, it is quite simple to independently make a structure for processing logs, boards and slats. Before starting work, you must select appropriate place. You can install a sawmill using a chainsaw in an old barn, garage, hangar, or even just under a shed. If the room for the unit is closed, then you should take care of the hood.

Chainsaw sawmill - option No. 1

To make the structure, in addition to a chainsaw, you will need:

  • two channels 8 meters long and 140-180 millimeters high;
  • two rails;
  • corners 50x100 mm and 40x40 mm;
  • segments water pipe 25 cm as ties;
  • steel plate 4-6 cm thick and 60 cm long;
  • movable hoses;
  • pipes with a diameter of 35-40 mm.

Making your own sawmill should start with assembling the base from rails and corners 50x100 mm turned upside down. They must be installed strictly parallel to the floor, so you need to use a building level.

  1. Along the length of the base, according to the drawing, holes are drilled in increments of 1-1.5 meters and with a diameter of 14-16 mm.
  2. Then, according to the number of holes, ties are taken and connected with bolts.
  3. Stands are made from metal squares and the base is placed on them. The distance between the outer posts and the base should be about 100 cm.
  4. To make the structure more rigid, braces between the posts can be welded.

After the base is completed and installed, you need to make a movable cart with your own hands. For this a corner is welded to the bottom of the steel plate 40x40 mm and the product is placed on rollers or bearings. Two corners are welded on top of the plate, to which a chainsaw is attached.

On last stage manufacturing work homemade sawmill it is necessary to make a structure for fixing the logs. To do this, movable hoses and pipes should be positioned at the required height and secured.

The first version of a homemade sawmill using a chainsaw is ready. There is another way to make a wood processing unit with your own hands. The tools and drawing for it will need the same, however, the design itself is more refined.

Do-it-yourself sawmill from a chainsaw - option No. 2

The structure consists of four main components:

  1. Driven saws.
  2. A mechanism for regulating the thickness of the board being produced.
  3. A mechanism for moving the saw part of the structure.
  4. Devices for fixing logs.

Since a chainsaw with a working engine and cutting teeth is already available, you will only need to make both mechanisms and a device for fixing logs with your own hands.

Mechanism for adjusting the thickness of the boards.

Logs are sawed by raising or lowering the base, which must be welded to the plate using four nuts with bent edges. At the top of this device lock nuts must be installed, which need to be tightened after the unit is adjusted to the desired thickness of the material being processed.

Mechanism for moving the saw.

The saw in the structure moves along the frame along guide angles, the distance between which should be 50 cm. To the racks it is necessary weld two rollers or bearings by 20 mm. The lower roller should keep the sawmill from lifting, and the upper one should rest on the guide angle.

Device for fixing logs.

On such a unit logs are secured using two ridges– stationary and moving by means of a screw. After the material to be processed has been installed, the moving comb is secured with screws in a stationary state. Now you can safely begin to operate a homemade sawmill made from a chainsaw.

A sawmill is an impressively sized The unit is quite dangerous to operate, therefore, before you begin assembling it, you should carefully consider the place where it will be used. It should be well lit, ventilated and have free space. The nearby warehouse for finished boards will greatly facilitate the process of processing the material.

For sawmill with electric motor You should very carefully install the necessary switches and circuit breakers, as well as do the wiring.

Since the most dangerous elements of the unit are all its cutting and moving parts, when assembling the structure they should be given special attention.

Before starting to operate the assembled equipment, it is necessary to check all fastenings and components, as well as the stability of the structure.

Operating instructions for a homemade chainsaw sawmill

After the structure has been assembled and tested, it must be tested in wood. To do this you need:

Jerky movements when cutting should not be made, as this can lead to the tire stopping.

It should be kept in mind that It is necessary to work in personal protective equipment, which include mittens, a robe, oversleeves and glasses. In addition, you should worry about protection for the moving frame in advance. It can be made from acrylic or transparent plastic. Such guards can protect against saw chain and chips.

A sawmill assembled with your own hands from a chainsaw will allow you to produce high-quality sawn timber correct form. Therefore, if you often have to work with lumber, then this homemade equipment, made on the basis of the attached drawings and videos, will become an indispensable thing in the household.

In the process various works Often there is a need for longitudinal cutting of logs or beams. For this, a variety of types of equipment can be used - from stationary sawmills to small installations, but these options cost a lot, and if you need to do a small amount of work, then sawing logs with a chainsaw will be the simplest and most rational solution.

Advantages of using this option

First of all, let’s figure out what advantages this cutting method has:

Ability to work in any conditions Unlike electrical equipment, which is afraid high humidity, the chainsaw is capable of working in the most unfavorable conditions, without causing any damage to the structure, because all components in the chainsaw are adapted to work on outdoors and even under precipitation
Performance If you are going to work long time, then you will need equipment with a power of about 7 horsepower or more, it can withstand significant loads, while the quality of work will be consistently high
Autonomy Since the device runs on gasoline, you do not depend on electricity and can build a structure for sawing in any location. convenient location. This is especially convenient when working in areas where there are no power lines
Convenience The inertial brake in chainsaws works faster than in electrical systems, A smooth start and adjustable chain speed ensure high quality work, even if you do not have such experience

Important!
In addition to all the above factors, we should not forget the low cost of the structure; purchasing a stationary sawmill will cost several times more.

Overview of some options

We will talk about the two most popular designs that provide best quality when working, and you yourself will determine what is more convenient and preferable in your case.

Homemade option

First, let's look at how to make a device for sawing logs with a chainsaw with your own hands.

The instructions for carrying out the work are as follows:

  • It is best to use a frame from an old one school desk or a square pipe with a side of 20x20 or slightly larger.
  • First of all, two clamps are made, these are elements 50-60 cm long, at one end of which a crossbar with two holes for tightening bolts and a small protrusion in the middle for clamping the tire is welded, an element of the same configuration is attached on top, the photo below shows already ready-made elements, as you can see, everything is quite simple, and having at hand welding machine, you can make them very quickly.

Sawing logs into boards with a chainsaw is the most convenient and quick way. With the help of special attachments and devices, independent production of almost smooth boards is ensured, the quality of which is in no way inferior to those produced industrially.

Attachments for sawing logs

Chainsaw - convenient universal tool in homestead farming. First of all, it should be taken into account that it has high power, compactness. Thanks to centrifugal clutch all systems and components of the mini-engine operate without overload for a long time; Power makes it possible to install any attachments. The chainsaw can be used in any position and in any terrain, since it is autonomous and has a diaphragm carburetor.

How to adapt a mechanism for cutting logs into boards? To do this, just install the appropriate attachments on the chainsaw.

To cut a log along its entire length, a nozzle for longitudinal sawing of logs in a horizontal plane is suitable. Thanks to it, the boards are of the same thickness. After the necessary proper drying, they are suitable for construction. The attachment is a small frame that is attached to the tire on both sides.

In addition, there is a lightweight nozzle that is fixed on only one side. As a result, the boards are not as smooth as in the first case. Fences and sheds are built from such boards.

An auxiliary tool is a drum debarker-finer.

With its help, logs can be easily cleared of bark.

The nozzle is a drum, works thanks to a V-belt drive. It is attached to the moving belts using special pulleys on both sides of the axis. By selecting the diameter of the pulley, you can select the optimal shaft rotation speed.

Sawing logs lengthwise

To obtain straight cut, you need to install a guide. It can serve as an industrial mini-sawmill. But such devices are expensive and not everyone can afford them. Therefore, logs are usually fixed homemade holders from boards with the same guide.

Sawing of logs into boards is carried out with a chain for longitudinal cutting. If there is none, a regular chain, sharpened at an angle of ten degrees, will do. Only in the process of work will you have to sharpen it from time to time. An attachment is installed on the chainsaw - a guide frame for an even cut.

To cut a log lengthwise, you must perform the following steps:

  1. Make a leading line. To do this, you need to fasten two straight long boards at an angle of 90 degrees.
  2. Place the log on the stops, thus fixing its position.
  3. Attach the nozzle.
  4. Using self-tapping screws, attach the supports to the ends of the log on both sides. Check horizontality with a level.
  5. Attach the leading ruler to the supports with self-tapping screws.
  6. Install another one horizontally support board, which should rest against the ground and slightly lift the log.
  7. Using a chainsaw with a horizontal cutting attachment, cut off the first piece of log.
  8. Move the guide ruler and fix it.
  9. Make a second cut of the log perpendicular to the first.
  10. There is no need to use the leading ruler any further. The resulting board will serve as a guide.
  11. Determine the thickness of the cut using the frame.
  12. Make the next cut perpendicular to the second. The result should be a piece of wood, the underside of which is covered with bark.
  13. Make a fourth cut to separate the remaining part of the wood that contains the bark. You will get an almost perfectly even block of wood.
  14. Next, cut the block to the middle.
  15. Turn it over to the opposite side and continue cutting until the end.

If the thickness of the boards does not matter, cutting off the edges with bark is not necessary. In this case, you can use an edger and cut into boards from the very beginning.

Making cross cuts

Cross sawing is used to cut logs into firewood, as well as to create cross-cut wooden disks for construction garden benches, decorations garden paths and so on.

Cutting a log crosswise is done as follows:

  1. Place the log horizontally on wooden supports 0.5 m high.
  2. If necessary, you can clear it of bark.
  3. Using an ax or saw, make marking cuts at equal distances from each other.
  4. According to the marks, cut the log.

Special attachments and chains are not needed for this work. A regular chain will do.

Maintaining safety during work

To avoid operational failures and accidents, safety precautions should be observed when working with materials and tools:

  1. When working, do not allow strangers, especially children, onto the work site.
  2. During work, you should use protective equipment against noise and sawdust that fly away during cutting.
  3. You should carry a first aid kit with everything you need to use in case of cuts.
  4. Using circular saw it is necessary to put a protective cover on it.
  5. Do not pour gasoline into a heated tank of a chainsaw.
  6. Use the chainsaw only for its intended purpose, do not turn it on full power if she is not at work.
  7. There is no need to press hard on the saw while working.
  8. The log for cutting should be installed on the right side.

Chainsaw serves convenient tool, which can be used for self-production boards It is suitable for use in household plots where it is necessary to repair or build new outbuildings. In such cases, a large number of boards is not required. Therefore, they can be easily cut from any logs in required quantity. Once you acquire the skill, the work is done quickly, and the quality of the boards is excellent.

For processing logs band sawmill it is necessary to adhere to the accepted technology. In this way you can get the maximum amount quality materials- boards and timber. But first you should familiarize yourself with the basic cutting rules.

Types of wood cutting

At the first stage, a carriage is formed from a log. To do this, cuts are made on both sides of it. In some cases, processing is performed on four sides. A map of the band cut of the workpiece is first drawn up, on which the dimensions of the components are indicated.

The determining parameter when choosing a scheme is the direction of processing of the log. In particular, the movement of the cutting edge relative to the annual rings. According to this, lumber of various qualities is formed, with a unique appearance. Not only their aesthetic qualities, but also their price depend on this.

The following types of cuts are distinguished:

  • tangential. The cut is made tangentially to the annual rings. As a result, oblong patterns in the form of arches and rings are formed on the surface;
  • radial. To perform it, perpendicular processing along the annual rings is necessary. A special feature is the uniform pattern;
  • transverse. Processing occurs across the fibers, the cut pattern is an even cut of annual rings;
  • rustic. Can be made at any angle, contains a certain number of knots, sapwood or other similar defects.

The woodworking industry often uses waste from band sawing logs - slabs. On one side there is a flat plane, and the other remains unprocessed.

To create the most accurate cutting, it is recommended to use special programs. They take into account not only the dimensions of the source material, but also the type of wood.

Sawing on a sawmill with log rotation 180°

To form maximum quantity boards, it is recommended to use a technology in which some belt processing processes are rotated by 180°. This allows you to achieve the maximum amount of lumber with various types cuts.

The principle of processing is to make initial cuts along the edges of the log, located at an angle of 90° relative to each other. They will serve as the basis for further tape cutting. Work is carried out on equipment with vertical arrangement cutting elements. The diameter of the trunk must be at least 26 centimeters.

Step-by-step order of work.

  1. Processing the side with the cut-off edge. The result is two boards.
  2. Rotate the workpiece by 90°. The cut is made from the opposite part. The number of products varies from 3 to 4.
  3. Repeated turn 90°. The main part of the source material is processed. Depending on what you plan, you may end up with 7-8 pieces.

Despite all my positive traits, this method has one significant drawback - low production speed. It is recommended to use it on equipment that has a block for automatically changing the position of the log relative to the cutting part of the machine.

The detailed diagram is most often used for the production of rustic boards, which have lower quality requirements.

Sawing on a sawmill with log rotation 90°

For the manufacture of tangential and radial boards, it is recommended to use a different technique. It consists of systematic strip processing of logs with simultaneous analysis of defects. In this way, products of the required quality can be obtained.

After delimbing, the workpiece is placed on the infeed bed sawing machine. Then you need to complete the following steps.

  1. Removing the primary slab. This is carried out until the width of the base is 110-115 mm.
  2. Removal of unedged boards approximately 28 mm thick.
  3. If the number of defects on the surface exceeds the required level, the material is rotated 90°. If the quality of the board is sufficiently high, the next one is cut.
  4. Repeating the operation.

A similar technique is applicable for processing units that have one cutting surface or have the function of temporarily dismantling the rest.

When enough large quantities defects, you can not put the workpiece aside, but rather process it by turning it 180°.

The above-described tape processing technique can be applied to create any configurations wooden products. Often the core area is used to form timber, and the remaining parts are used to make boards. But there may be exceptions - it all depends on the required shape of the blanks.

The quality of work is affected Current state sawmills, saw sharpening level and processing speed. These factors must be taken into account before starting the production process. If necessary, preventive maintenance or repair of equipment is carried out.

The video shows the technique of sawing logs on a homemade band sawmill:

Leading manufacturers of household and professional chainsaw equipment offer a number of the latest models with universal properties. Submitted wide choice chainsaw attachments help to use the working capabilities of the tool with greater efficiency.

A significant portion of fairly expensive household tools are used from time to time. The use of a chainsaw as a drive for several types of replaceable equipment allows you to mechanize labor-intensive household work with less material costs.

The list of operational capabilities of chainsaws has been expanded and successfully implemented due to removable additional equipment. It includes attachments and accessories for a wide variety of purposes.

Most of The range of attachments is aimed at completing branded models. The capabilities of budget chainsaws in this regard are very limited.

  • Even a small kit allows you to mechanize a significant part of the household work associated with special treatment wood and metal, drilling wells, caring for ornamental shrubs.
  • It is possible to use the saw as a boat motor, lawn trimmer, gas cutter or household compressor.
  • The efficiency of using replacement equipment is facilitated by stable traction characteristics and efficiency of power units, adaptation of branded chainsaw equipment to difficult climatic factors.

In practice, it has been proven that chainsaws from leading brands can be successfully operated in a wide temperature range.

Combination of angle grinder and gas cutter


The universal grinder attachment is driven from the drive shaft of the drive sprocket via a V-belt drive. The device is mounted on the saw body with studs designed to fix the saw bar.

Diameter emery wheel selected depending on the engine power and the characteristics of the work to be done. The USHM-1 petrol cutter attachment copes well with abrasive cutting of natural and artificial tile-cladding materials, metals, and cleaning of welded joints.

The angle grinder-1 works with standard and diamond wheels with a diameter of up to 20 cm, with a mounting hole of 22 mm. An abrasive attachment for cutting metal can be a good addition to the tools of a home workshop or equipment of a small car service.

Chainsaw as a drive for a light boat

Popular nozzle " boat motor» is activated by means of a gearbox and pulley extension, which is mounted instead of the drive sprocket. Depending on the engine power, a boat equipped with a two- or three-bladed propeller can reach speeds of up to 20 km/h.

Drilling and compressor equipment

Simple in design and easy to use ice drill attachment in winter time used in fish farms to supply air to frozen bodies of water. The effectiveness of using combined equipment has been confirmed in practice.

Lightweight, compact and quite productive ice auger - included in the equipment set for amateur winter fishing. As a result of natural selection, the high demand for the most successful developments.

In particular, excellent operational properties characterized by the MB-2 Ice motor drill. The nozzle is driven through a reduction gearbox, which reduces the shaft rotation speed to 150 rpm. This model differs from analogues of the same type in that it requires minimal installation time, ranging from 5 to 10 minutes.

The replaceable compressor nozzle is inferior in operating parameters to many household-grade mobile units. However, for the aeration of small stocked reservoirs, the operation of pneumatic paint sprayers and sprayers, its performance is sufficient with a reserve.

Replacement equipment for working with wood


Milling and drum attachments for removing tree bark and cleaning construction wood from surface irregularities are presented in several types.
The most famous are the Bark Beetle and Debarker models, with a working grip from 80 to 100 mm. The cutter attachment specializes in advanced cutting of construction wood. With its help you can plan logs, cut cups and mounting grooves.

The equipment is used in wood construction for pre-assembly processing of industrial wood. The products are equipped with removable knives that can be easily dismantled for sharpening cutting edges and a set of extended threaded fasteners. The bark beetle attachment is activated from a pulley, which is installed instead of the drive sprocket.

With appropriate drive power, bark stripping attachments can be used to remove knots, sharpen stakes, and create corner locks for log cabins.

With precise adjustment, the bark beetle replacement device can be used as a plane attachment. The quality of surface treatment of construction wood is determined by sharpening the cutting edges of replaceable knives.

Devices for longitudinal sawing of construction wood

In the standard version, for longitudinal and diagonal cutting of wood, they are used with a certain sharpening angle. Special devices are no less effective and productive.

Sufficiently durable nozzle for use rip sawing, which does an excellent job of sawing logs and boards, costs about 2,000 rubles. This is the approximate cost of four saw chains, whose service life is very limited.

Replacement household equipment


This list includes devices designed for caring for ornamental shrubs and lawns. The Hedge Cutter attachment will help tidy up a living fence or clear an area of ​​young growth in a short time.

The removable rotary trimmer attachment is inferior to a household lawn mower only in terms of ease of operation. Its design allows you to process lawn areas with fairly high quality and in an extremely short time.

Traction devices


The cable “Winch” installed on a powerful chainsaw is characterized by wide functionality. The pulling force of the nozzle varies in the range of up to 2 tons, the range of action is up to 30 meters.

In the operational capabilities of the traction device:

  • skidding of felled trees;
  • removing stuck vehicles;
  • lifting work and moving non-standard cargo by dragging or using rollers;
  • plowing of heavy soils on land plots difficult to reach for tractor equipment.

Motorists living in regions with bad roads willingly equip their cars with chainsaws and winching equipment.

Chainsaw as a pumping unit


The autonomy of the gasoline drive is highly valued in irrigated farming areas. Compact and mobile pumping units are effectively used to supply water to areas located at a great distance from power sources.

Such devices are in particular demand in private and small-scale farms, for watering crop areas, as well as drawing water from wells and artesian wells.

Alternative developments

As the popularity of replacement equipment for chainsaw equipment grows, new options are being developed. The list of offers has been supplemented with several types of removable attachments for the Wood splitter. The device is a rotating conical rod with a screw thread.

Advantages of replaceable attachments

In the first case, there is a significant cost savings on purchasing the kit household tools for various purposes.

  • The price of several attachments is 2-3 times less than the cost of a standard set. In terms of functionality, many branded models are not inferior to highly specialized household analogues.
  • Replacement attachments for chainsaw equipment occupy less space, prompt replacement of a standard saw bar with any replaceable equipment, provided you have the skills and the appropriate tools, is carried out within a few minutes.
  • The use of attachments increases the payback of a chainsaw several times. The tool, which is most often used for harvesting fuel wood, can be used to solve many household and construction problems.

Flaws

The technical and operational characteristics of chainsaws are focused on a given level of workload and special operating modes. Some owners of prestigious professional chainsaws are against the use of attachments.

Refusal is motivated by necessity long work engines at maximum speed, in some cases due to a lack of torque, a forced reduction in the overhaul life.

As a result of the studies, models of cable winches, bark peelers, wood splitters and compressors were recognized as safe for the resource and technical condition of the attachments.

  • In particular, when working with angle grinders, the air intake filter becomes intensively clogged.
  • Installation of boat equipment and a pump nozzle requires a long period of operation of the high-speed chainsaw engine at maximum mode.

These shortcomings are partially or fully compensated by the increased wear resistance of modern power units, an increase in the actual service life of chainsaws from 1500 to 2000 or more operating hours. The durability of engines is also positively affected by the use of heat-resistant branded motor oils.
