Make it from a chain saw. Do-it-yourself power saw from a grinder. Option for making a simple sawmill based on a chainsaw

The cost of lumber is quite high for most private craftsmen involved in private construction, which forces them to show miracles of ingenuity. Using simple technologies sawing logs, you can not only save money, but effectively and efficiently use all available personal resources.

First of all, this concerns wood and equipment, because they lay the foundation successful work. An excellent alternative to a stationary sawmill is from a power saw that you can make yourself.

What can be made from an electric saw

Since sawing logs into bars and boards always requires cutting equipment, factory sawmills use rack (band) and circular saws. Naturally, for construction small house or making several cubes of boards, it is impractical and expensive to purchase such a machine. The best alternative he might become homemade design based electric chain saw.

Its potential is quite enough to satisfy the small needs of private developers, and just ordinary home craftsmen who cannot afford ready-made lumber. The electric saw here is the main device, combining a universal mechanical feed of the cutting tool and an electric drive. Chain sawmill the best way, unlike a circular saw, is suitable for longitudinal bucking and sawing logs, as it has:

• rough cut sufficient for efficient sawdust ejection;
• capaciously arranged electromechanical feed of the cutting tool (chain);
• relatively low cost.

How to make a sawmill from an electric saw with your own hands

In fact, the cost of all equipment depends on the task at hand. It is important to correctly assess the potential of existing equipment. Everything must be taken into account - from the density of the wood to the power of the electric motor of the saw itself. However, all these calculations are quite simple. In addition, in almost any forested area it is possible to buy round timber, which is significantly cheaper in cost than lumber.

For creating to make a homemade sawmill using an electric saw you will need:

1. 1. Bed, in the amount of two pieces.
   2. Fasteners both for the saw itself and for fixing the workpiece (log).
   3. Electrical wire with switch and plug socket.

Advice: In most cases we are dealing with wood that has low density fibers These are pine, linden, and similar trees, which will make it easier to select a saw based on an electric motor. For efficient work A saw with a power of more than 1.5 kW will almost always do. The only limitation here will be the speed of its operation. The stronger the engine, the faster the work and the cleaner the cut.

The above list should be discussed in more detail using one design as an example, since it is not possible to describe all of their modifications in one article. This is perhaps one relatively cheap, but very popular project. And the quality of the cut is almost as good as the famous mobile sawmill Logosol.

bed

There are two of them in the design under consideration: one for the saw, and the other for fixing the workpiece. The operating principle of this unique chain sawmill is based on manual feeding of the electric saw to the workpiece. It is easy to understand that it must move along a rigid structure, which is usually called the machine bed. In our case, it is rigid, but necessarily smooth in all two planes edged board. To make the guide rigid, you need to frame it with two tin corners. They are easy to buy at a metal building profile store.

It is attached to wooden poles. As such, you can use blanks (wood logs) or cuttings of timber with a cross-section of more than 18 cm. The frame itself will stand more stable, and it is also more convenient to fix a board of maximum width.

A second frame should be placed a little lower to secure the workpiece. Its height is selected experimentally, but it is better to use pads made of boards of the exact size. The structure of the log frame itself is located on the same blocks.

Connecting them together is a personal preference, since to work it is enough to firmly dig in or screw its posts. The distance between two parallel beds is set arbitrarily. However, given the length of the saw bar, you should not install it more than 3 cm away. It is better that it stands close to the saw guide and strictly parallel horizontally relative to it.

Fastening the saw and fixing the workpiece

To fix the electric saw on the guide frame, use a metal corner. A saw is attached to one shelf using bolts. To the other cheek of the corner, which lies on the plane of the guide board, two additional aluminum, but better steel, corners are fixed.

The main angle should have a wide cross-section, preferably more than 10 by 10 cm. This way the saw itself will sit more rigidly, and it will be easier to screw the guide angles from the bottom of the second shelf of the square. The guide angles should be secured with a small gap, taking into account the width of the guide frame. This design allows the saw to be easily removed from the stand. This will be more convenient for setting up equipment and dismantling it at the end of work.

Fix the preparation can be done in several ways:

• Along the ends of the log using temporarily driven nails
• Using special pads (saddles curved in a semicircle)

Fastening logs using hardware is a temporary option when you need to cut several logs. However, for constant and mass sawing it is advisable to make special fasteners. Saddles that approximate the radius of the logs are usually made of rigid steel tape. As a last resort, parallel bars are used on each stand of the frame.

Electrical equipment

The electrical equipment of a homemade sawmill cannot be called complex, since most of it is already present in the saw. You will need electrical wire, a special connector and plug, as well as a switch. The entire future electrical circuit will look like a universal extension cord, similar to the cord of a floor lamp or sconce.

The presence of a switch will allow you to better control the operation of the homemade product, and a special connector for connecting the saw fork is convenient for moving, as it does not get stuck anywhere. To prevent the power supply cord from accidentally jumping out during operation, it must be secured to the saw itself with a bridle or with electrical tape. The presence of an overload and short circuit protection circuit breaker in the electrical panel will help ensure safe operation.

Conclusion

A chain sawmill based on improvised means is no worse than factory equipment. The only thing it loses in is the speed of wood processing. But considering the nature and purpose of use homemade equipment, That is unnecessary. With only a power saw on hand and some money for assembly electrical extension cord, you will get a great opportunity to have your own sawmill.

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

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

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

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

• disk;

• tape;

• tire

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

Making your own splint saw

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

To make a chain saw you will need certain materials:

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

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

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

Assembly of the cutting part

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

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

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

The upper part of the axle is attached to metal profile. The opposite part of the profile is welded to the frame in which the electric motor is installed. Thus, the rectangle is formed as follows: the lower part is the tire, on both sides of it is the axle and the electric motor, the upper part is the bar.

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

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

Transferring the body with the saw to the base

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

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

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

Making a circular saw from a hand-held circular saw

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

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

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

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

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

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

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

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

What is a chainsaw sawmill?

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

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

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

The photo below shows both versions of sawmills made from a chainsaw and a band saw blade, which were made with your own hands.

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

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

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

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

With the onset of autumn, the sounds of gas and electric saws begin to be heard more and more often. This means that the firewood harvesting season is in full swing. However, for what purpose might a sawmill be needed when a mobile gas-powered tool does an excellent job of preparing firewood? It is easier to cut firewood when a longitudinal cut is made using a chainsaw, but when it becomes necessary to cut the logs into boards, you cannot do without a sawmill for these purposes.

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

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

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

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

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

How to make a sawmill from a chainsaw

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

Second option when needed home sawmill, in the manufacture of which you will need:

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

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

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

Drawings of a sawmill using a chainsaw photo

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

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

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

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

Do-it-yourself chainsaw sawmill, instructions with photos

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

Option for making a simple sawmill based on a chainsaw

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Varieties of homemade chainsaw sawmills

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

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

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

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

How to properly saw boards on a homemade sawmill

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

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

The result of making your own sawmill from a chainsaw

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

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

The desire to improve an existing tool comes for a reason. The main goal of such an experiment is to save money. Indeed, why buy several tools if you can use different attachments and make a multifunctional tool.

The grinder is known to every household homeowner, because with its help you can cut metal, stone, and polish the surface. But trees cannot be cut with such a device; difficulties arise due to the small diameter of the disk. So craftsmen come up with various attachments that make working in the garden much easier.

Why do they resort to a homemade option?

Often, it is homemade options tools or improving existing ones is done out of a desire to save money. Using improvised means and parts left over from equipment or machinery that has fallen into disrepair, craftsmen skillfully make various devices, such as, for example, a chain saw from an angle grinder.

The second reason can be considered the desire to have a multifunctional tool that will help ease numerous tasks on the farm. The undeniable advantage of this homemade apparatus is space saving. After all additional nozzle takes a lot less space in a barn or garage than a full-fledged device.

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

Factory attachments

Now on sale there are special attachments for grinders in addition to discs. The grinder comes with a device that can be used to turn it into a chain saw in a short time. Supplied in two separate boxes containing an angle grinder and a chain saw.

Set of nozzles

The estimated cost of this set is $83.

Grinder electric saw

Anyone who has encountered working with wood needs to have a saw in their arsenal of tools, with the help of which it is much easier to carry out sawing work. Below is a diagram for converting an electric saw that can be made from a grinder

In order to convert an angle grinder into an electric saw, you must have with you:

• Welding apparatus;
• Adapter for cutters;
• A small-thick metal roller;
• Gearbox;
• Saw part.

The first thing to do is to weld a movable wheel at the end of the boom. It is very important to make sure that this wheel and the circuit have the same contour. If this nuance is not taken into account, the chain will fall off or become very tense. After this, the adapter for the cutters is attached to the wheel. The adapter should not be fixed permanently; it should be removable, otherwise difficulties may arise during operation.

A simple and reliable modification option is the following method. We take a bar from an old chainsaw, a sprocket and a chain. Two perforated corners are twisted together. Cut a hole in one for the nut. We will attach an asterisk to it, and in such a way that it will be possible to attach a corner to the casing.

We attach a tire to the remaining corner. After this, we attach the sprocket and connect the chain. That's all the manipulations that result in an effective saw.

Another visual video review demonstrating a homemade product

The main advice that should not be neglected is to follow safety precautions when working with such tools. A chainsaw or electric saw in a homemade version can be dangerous and traumatic. If you decide to take this step, then follow all the recommendations, drawings and diagrams that are indicated in the instructions for the adapter.

Own sawmill is a profitable enterprise, since wood is one of the most popular building materials. You can acquire such equipment by purchasing it from finished form or by building it yourself. The choice of option depends entirely on how many cubic meters of wood will be processed regularly. Experts recommend familiarizing yourself with the types of saws first. Purchasing a finished product will help save time, and the finished product will fully meet the owner’s requirements.

Types of frame units

It is recommended to pay attention to a sawmill made from an electric saw, in which the frame is the base. Typical factory-produced products are expensive and are considered professional equipment with rich functionality and high level productivity. The finished tool will be able to pay for itself after a few months. It is necessary when there is a large volume of forest. In other cases, it is advisable to purchase or make your own sawmill from a small electric saw.

Equipment designed for sawing wood is presented in a wide range. Most of them are too expensive for a typical country farm, and processing volumes are scale-oriented industrial enterprises and reach several thousand cubic meters per day. Experts distinguish 3 types of such devices:

• disk;
• tape;
• tire

Circular saws are the most common on the farm. Among their disadvantages are the increased volume of waste compared to tape counterparts and the high cost of high-quality discs. Electric band saws are recognized as one of the most profitable options. They are unpretentious to weather conditions and produce little waste. It is recommended to use them with wood whose diameter does not exceed 70 mm. The design of the device complicates the process of reproducing it yourself.

Tire sawmills are in great demand among hobbyists. They are capable of processing large volumes of wood. A do-it-yourself tire sawmill can be made more easily and quickly compared to analogues.

Self-production

To make a sawmill with your own hands, you will need to create a plan. Manufacturing process carried out independently if the sawmill will be used irregularly and there are certain materials (metal profiles, engine).

Electric sawmill own production has more modest performance than its factory counterpart. Homemade device used for the production of beams and boards. First you need to determine:

• the length and diameter of the logs that will be processed;
• unit performance;
• motor – gasoline or electric;
• installation location.

The carriage can be used as a motor for a semi-professional chainsaw. Experts say that household chainsaws and electric chain saws are not suitable, since their motors are not designed to perform such actions (lack of required power).

The bed, base or frame must be sufficiently stable and reliable, since the safety of the master and the quality of operation of the equipment depend on this. The length of the frame is determined taking into account the length of the wood that will be processed. Guides can be made from pipes, angles, or U-shaped profiles. The thickness of the metal is selected taking into account the weight of the wood being processed. For a carriage with a saw, you will need 3-4 mm of metal. It will be able to support the weight of the fittings and the motor.

The choice of disk or tire depends on the type of device being manufactured. Their length reaches 40-50 cm. The amount of waste can be reduced if you use chains with a small cutting thickness and a special type of tires. The sharpening angle of the chain should be 10°. Experts recommend making a device for fastening round timber in the form of a low stationary unit.

Step-by-step instruction

To make a sawmill for sawing with a disk, you will need to place the carriage at the top of the structure. Guides made from a 50 mm corner must be 5 m long. If the equipment is stationary, then holes will need to be drilled in the concrete and in the corner in increments of 15 cm. The structure is attached to the floor using dowels.

The device for fastening the log can be made from a channel or a U-shaped profile. The edges must be welded to the corner. Additionally, it is necessary to make holes for the bolts so that the log is fixed in the profile. The thickness of the processed logs will not exceed 40 cm, so 10, 15 and 20 cm are measured from the center of the profile. Holes for stops will be located at these points. More reliable fixation can be ensured by installing a movable clamp with teeth on the first and last profiles. The retainer is made from metal sheet 4 mm thick. The teeth are cut using a grinder. It is necessary to make additional holes in the profile and the retainer so that the latter unit can be easily dismantled and reinstalled.

The next stage involves the manufacture of the carriage. The design must be reliable, given the three-phase motor with a power of 3 kW. The height of the product should be 1-1.2 m. It is necessary to mark a corner 4 mm thick and 40 mm long. Then you need to cut the elements. The carriage design is welded and requires joining of parts. At the ends of its corners, holes are made for the wheels.

Next comes the installation of the motor with the disk. It is desirable that its height can be adjusted, and the device can operate in two positions - vertical and horizontal. The height of the unit can be adjusted using two pipes, which are recommended to be welded to the carriage frame.

At the next stage, you will need 2 channels welded to each other and a sheet of metal 6 mm thick. The channel is attached to the pipes using U-shaped clamps with a diameter of 10 mm. At its ends you will need to weld pieces of metal with holes for clamps, which should both sit tightly on the pipe and, if necessary, slide along it. It is advisable to adjust the height using 2 threaded rods. On top, in the carriage profile, you need to make holes for the rods.

A nut is welded to the ends of the profile on which the motor is located on both sides, into which you need to screw a rod and weld the sprocket from the bicycle. On both sides there are 2 rods with threads and stars. Between them, 2 large bicycle sprockets are installed, which will have to be tightly connected. As they rotate, the motor will rise or fall.

By creating conditions for rotating the motor both horizontally and vertically, you can achieve rotation of the disk in 2 positions. The frame is assembled based on the dimensions of the disk and engine and welded to the movable profile. It is necessary to attach 2 bearings and make 4 holes in the steel sheet. They are necessary for attaching the electric motor, to which you will need to weld 2 metal rods, focusing on the diameter of the bearings. The structure is then firmly attached to the frame. On the back side there will be a handle with stops. Protective cover made from of stainless steel and fastened with self-tapping screws to the frame with the motor. A control panel with “Start” and “Stop” buttons is connected to the fixed motor with the disk.
