Do-it-yourself sawmill from an electric saw. Do-it-yourself power saw from an angle grinder Electric chain saw from an angle grinder: step-by-step instructions

Circular electric saws are extremely necessary tools For household. Thanks to their technical and functional properties, today no one can do without them. furniture manufacturing or carpentry shop. And in private households there are many problems that would be more expedient to solve with their participation. The only thing that limits their use today is their cost, which is growing every year, as is the human need for them. One of the ways to overcome this barrier and acquire such a universal assistant is to assemble a homemade circular saw,

Considering the load and operating cycle of electric saws, for them home production you will need an equally reliable basic electrical appliance. Craftsmen advise using a grinder or an angle grinder, which almost everyone has. Its traction potential will be sufficient for sawing wood, cutting beams into slats and other tasks that most users set for it. Let's look at several ways to make an electric saw from a grinder at home.

DIY circular saw: the easiest way to make it

In order to start assembling a homemade product, you will need:

• metal clamps;
• electric drill;
• toothed disc;
• several pieces of metal corner;
• bolt ties modifications M3 or M5;
• working gearbox;
• rods made of high-strength steel;
• wrench.

The power base of the future design will be the engine from a household grinder.

Work progress step by step

1. the previously installed disk is first removed from the grinder;
2. Take a disk with teeth for woodworking, which is tightened with corners. A gap of several millimeters is left, which is adjusted using a bolt tie;
3. The body of the grinder - the future electric saw - is covered with clamps. A double metal strip with a thickness of at least 1.5 mm is passed through the bottom of the tool;
4. The grinder gearbox is pre-disassembled. You need to make holes in it to attach the handle. The last part can be made of a metal tube, the shape of which should be slightly rounded;
5. for adjusting the gaps between the side stop and base surface 4 holes are drilled in the gearbox for screwing in bolts;
6. The handle is bolted to the gearbox. Its end protruding outside the electric saw is given a horizontal position, holes are drilled and the axis is fed. If the handle is D-shaped, an adapter is installed between the handle and the gearbox - a tube made of thick-walled metal;
7. the rods are cut into 6 cm pieces, which are given a loop shape;
8. washers are fixed in front of the stop, thereby correcting the gap;
9. the handle is connected to the body with an electric motor.

By supplementing such an electric saw from a grinder with your own hands with a stationary base made of chipboard or stable plywood, you can make a stationary circular electric saw for a workbench or desktop.

In both options, it is very important not to make a mistake with the choice of disk and correctly calculate gear ratio. It is advisable to focus on single-phase asynchronous motors, which are equipped with most angle grinders. Three-phase motor systems, which can also take place in a similar design, should not be used without additional capacitors. A separate button can be used as a starting capacitor. In this option, you will need to consider additional grounding and check the electrical safety of the homemade product.

Electric chain saw from an angle grinder: step-by-step instructions

In order to recreate a chain saw based on a working grinder, we will need:

• Bulgarian herself;
• drive sprocket, which is best bought new, but if you have a working spare part from an old saw, you can limit yourself to the used option;
• metal to create a bracket to which the guide will be connected;
• a set of saw sets consisting of a bar and chain;
• a set of tools, including a drill;
• bolts.

The build process looks like this:

1. 1. unscrew saw blade from Bulgarian;
   2. make holes in the bottom of the metal casing of the device;
   3. bolt the bracket to the protective shield;

1. 1. a sprocket is screwed onto the motor shaft;

1. a guide is secured behind the bracket ties;
2. After the chain is put on and straightened, the bracket bolts are tightly fixed.

After this you can start working.

Advantages and disadvantages of homemade electric saws from an angle grinder

Electric saws, which today can not only be bought in a store, but also made at home, in addition to their main advantage - low cost of their production, have a lot weaknesses. Namely:

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

Stationary sawmill – indispensable assistant in everyday life and professional carpentry. It copes well with those tasks where the efforts of a conventional circular or chain saw are not enough. Among the areas of its application are longitudinal sawing and processing of logs, furniture production, construction, and industrial firewood procurement. Even with such a large list of advantages, not everyone can afford this purchase: its current price is very hard on the pocket and puts off the prospect of purchasing for many years to come. One of the ways to solve this problem is considered to be homemade electric saws, popular not only among amateurs, but also among professionals. Due to the relevance of this topic, we will consider one of the options for creating a sawmill from an electric saw with your own hands.

Homemade sawmills from electric saws: design options

Among all the variety of homemade products made from electric saws, sawmills are the most popular and widespread product that craftsmen have been producing for many years. Factory analogues of such devices are quite expensive due to their high performance. They are capable of processing thousands of cubic meters of timber per day of operation. When there is neither such a scale of woodworking nor finances, you can pay attention to one of 3 types homemade saws oram:

• tape; They have a complex design, but are adapted to any working conditions.
• disk; Quite easy to assemble, but not reliable, which is why they are in demand among amateurs. Circular sawmills based on electric saws are quite common in everyday life, productive and versatile in the tasks they perform;
• chain

In view of this, we will dwell in detail on their manufacturing technology.

Circular sawmill from an electric saw: detailed description and drawings

Before making a homemade sawmill from an electric saw, you need to decide on:

• the length of the materials that will be processed on this machine;
• volumes of workpieces;
• future homemade location.

Special attention should be paid to the choice of disc blade. Discs with a size of 400-500 mm, which are most often used in modern circular saws, are more than suitable for these purposes. And the problem with sawdust can be solved by using a disk with a minimum thickness.

Construction of a circular sawmill based on an electric saw

The design of any homemade sawmill based on an electric saw implies the presence of:

• frame element - a load-bearing part that connects all other parts together;

• motor part - it is advisable to focus on three-phase modifications of electric saws: household models powered from a 220 V network may be low-power;
• cutting set - the disk is installed in one of the planes - horizontal or vertical;
• load-bearing unit - for everyday tasks, an ordinary workbench or table on which the logs will be fed by hand will do. For more complex design complemented with a mobile carriage;
• adjustment mechanism - controls the electrical circuit of the homemade product, starts and turns off the motor. Most often located on the frame.

Assembly sequence

• installation of the frame frame - its dimensions are selected individually, taking into account the diameter of the disk and the dimensions of the motor. 2 bearings are attached to it and 4 holes are drilled for aggregation with an electric motor;
• the plane along which lumber will be fed. For small-scale work, you can use a ready-made stationary workbench or work surface, which must be installed strictly horizontally. It is very important that its longitudinal axis corresponds to the axis of the frame base;
• movable carriage approximate size should reach 1 m. Mobility will be provided by wheels, which will be installed at the end of the corner;
• aggregation of the motor with the disk - it is better to give preference to those sawmill designs where the height of the blade block could be adjusted manually. To do this, two pipes are attached to the carriage, to which they are welded metal channel. Through metal linings they are attracted to the pipes by clamps. Raising or lowering will be done by two steel rods. The movable position of the engine will be ensured by bicycle sprockets connected to the ends of the profile with the motor, connected to it through a threaded rod.

To improve the results of your efforts, the homemade product can be strengthened with a second circular knife. As in industrial analogues, their location must be strictly perpendicular to each other. For sawmills with a power of more than 3 kW, an additional traction device is not required. Otherwise, a second motor is taken and a second drive is created.

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 we will present two options for homemade saws: a 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 and also stock up 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 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, homemade sawmill will be inferior in characteristics to factory 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).

Any engine can be used as an electric motor, for example, from a semi-professional electric saw, from an old grain grinder or purchased specially.

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

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 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 table top to the table.

A circular hand saw is attached to the bottom of the tabletop. 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.

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 wood will be processed regularly. Experts recommend familiarizing yourself with the types of saws first. Acquisition finished product will help save time, and the manufactured one 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 considered professional equipment with rich functionality and high level productivity. Ready tool can 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 weather tolerant 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. Tire sawmill can be made with your own hands more easily and quickly compared to analogues.

Self-production

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

A sawmill made from an electric saw of our 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 special type 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.
