How to make a chain saw from a grinder. How to make a saw out of a grinder. Do-it-yourself chain saw from a grinder

An angle grinder, also known as a grinder, is an indispensable tool in the arsenal of any owner, used for cutting, grinding and polishing metal and wood. You can significantly expand the functionality of this tool using homemade devices which we will discuss in this article.

The publication will consider a home-made frame for the grinder, which makes it possible to turn the angle grinder into a full-fledged cutting machine from a grinder, as well as other simple designs that can be made at home.

1 We modernize the grinder with our own hands - we make a cutting machine

The key advantage of an angle grinder is its mobility - it is a compact tool with an extremely wide range of applications. However, it also has disadvantages, among which are difficulties in processing loose parts, during cutting of which strong vibration appears (which can cause the destruction of the abrasive disk at high speeds) and the difficulty of maintaining the required dimensions of workpieces when cutting several structures of identical length.

The above disadvantages do not appear when the angle grinder is equipped with a cutting machine, which significantly increases the convenience of cutting both wood and metal. The manufacturer of such a machine for a grinder can be done independently, you will need:

profile square pipe 40*40 and 20*20 mm;
rectangular profile 40*20;
metal corner 32 mm;
bearings with a diameter of 32 mm;
studs M12;

When assembled, a home-made machine for an angle grinder is a square frame made of a 40 * 40 mm profile, reinforced with cross bars. A rocker arm is fixed on the frame - a mechanism holding the angle grinder, which allows vertical plane change the position of the tool.

A homemade stand for a grinder is made according to the following algorithm:

The resulting homemade frame for the grinder is quite simple to operate. You need to install the angle grinder in the seat, position yourself to the right of the tool, put the workpiece on the supporting frame and lower the adjusting lever with your right hand. The cut itself is made in the space between the transverse jumpers of the frame.

1.1 Circular saw from grinder

Making a circular saw out of an angle grinder is even easier than a cutting machine, since there is no need to perform a large amount of welding work. You will need the following materials:

old table;
metal corner;
construction clamps or corner;
screws, nuts.

We note right away that a low-speed angle grinder is needed here (within 4-5 thousand rpm) or with speed control, since units with high speeds are not suitable for cutting wood - due to rotation, the workpiece will be torn off from the circular saw, which endangers the machine operator. For sawing wood, it makes sense to use an angle grinder with a disc with a diameter of 150 or 180 mm.

A wall chaser is a tool used to form grooves and furrows on the surface of concrete and wooden structures. A wall chaser is necessary when reinforcing the laying of the foam block, hidden laying of wiring and cables. You can make such a tool with your own hands from an angle grinder, without spending about 5-10 thousand rubles on the purchase of a factory unit.

An angle grinder turns into a full-fledged wall chaser after being equipped with a special casing made of wood or metal, which acts as a limiter that holds the circular saw at the same depth along the entire length of the cut.

It makes sense to make a casing from sheet metal 2-3 mm thick. Decide on the width of the structure - the distance between the two side walls of the casing, it depends on the size of the disks used. After the main part of the structure on the casing, it is necessary to fix the clamp for the installation of the angle grinder. The fastening should be as strong as possible (welded with a continuous seam), since the vibration that occurs during operation can damage the connection.

A mounting socket is welded to the side wall for attaching the handle. As a nest, you can use a piece of pipe with a hole drilled for a stud or bolt. In the upper part of the casing, it is necessary to provide a nozzle for a vacuum cleaner; without it, dust can clog the structure from the inside.

Please note that the angle grinder can only make grooves when two diamond discs are installed. In this case, the first disk is mounted on the rod in the standard way, and the second - through a special spacer nut (the spacer must come with the angle grinder, it can also be bought separately). The thickness of the nut in this case determines the width of the formed strobe.

2.1 Varieties of disks for angle grinders

In conclusion, a few words about the varieties of discs for grinders. All disks are classified into four main groups - cutting, grinding, sharpening, peeling.

Cutting discs are available in diameters of 115, 125, 150, 180 and 230 mm, their thickness can be 1-3.3 mm, they have Blue colour. The marking indicates the type of abrasive material: A - corundum, C - silicon carbide, AS - electrocorundum. Also, the markings indicate the numbers indicating the graininess - the larger it is, the higher the cutting speed will be and the lower the accuracy. The mounting hole in the cutting discs is reinforced with steel plates, which ensures its strength, since the ring experiences maximum loads during rotation.

For cutting stone materials, special diamond discs, which are continuous and segmented. The latter option is designed for heavy work - they can cut asphalt, granite, marble. Cutting tiles with an angle grinder can be performed using solid discs, they are focused on working with soft material and differ from segment analogues in the worst natural cooling.

Grinding discs are extremely variable, they are available with different abrasive surfaces - from emery, to sponge and felt (polishing discs). Grinding itself is carried out using special pastes that moisten the treated surface and thereby reduce the amount of dust released.

Roughing discs with metal pile are used to remove old paintwork, scale, cement mortar. There are also diamond roughing discs, which differ from cut-offs in the shape of the edges. Such discs are not used on metal surfaces, they can only be used on stone and concrete.

A circular saw is one of the universal locksmith tools that is widely used in various sectors of the economy, in metal and woodworking, furniture production and other tasks. The main advantages of disk machines include ease of operation, high speed and cutting accuracy, as well as good maintainability and the ability to quickly replace the cutting disk. If you do not have a professional or household disk machine, you can make it yourself on the basis of a conventional angle grinder (angle grinder) or grinder.

Self-manufacturing a cutting machine based on a grinder justifies itself from an economic point of view: for performing one-time household chores (cutting logs, metal and wooden profiles, timber and corners, as well as ceramic tiles and other materials) it is unprofitable to buy expensive machine tools. With basic skills in working with welding machines and other tools from the locksmith's arsenal, you can easily make a circular, pendulum or chain saw with your own hands.

We invite you to familiarize yourself with detailed instructions, drawings and tips for making a saw from a grinder with your own hands on a video where you will find many useful practical advice and learn important theoretical information for retooling tools (photo instructions also complement the video for your convenience).

Do-it-yourself circular saw from a grinder

Circular saw designed for simple, but voluminous woodworking work - cutting timber, boards, lining, etc. - can be made quite simply on the basis of an ordinary grinder. It is recommended to take an angle grinder with a disk diameter of at least 125 mm to make the tool universal in use. You can make a circular machine based on an angle grinder according to the drawings and without based on the old kitchen table, as well as homemade frame structure metal or solid wood.

The main requirement for the base is the stability of the structure (it should not loosen) and a flat bed on which the grinder will be fixed. It is necessary to make a slot for the saw blade in it. The bed can be made of wood, chipboard, plywood, sheet metal, plexiglass and other hard materials with a thickness corresponding to the loads that will be placed on the structure during operation.

Since the drive of the circular saw from the grinder will be mounted from the bottom of the table cover, it is better to make the cover hinged with strong hinges. Do not forget also about the guide bar - it can be made from an ordinary metal corner. In this case, the bar can be fixed and sliding. The most important part of making a circular saw is fixing it securely to the bed. To do this, you can use strong self-tapping screws, as well as make your own special brackets for fixing the angle grinder on the table top.

Do-it-yourself pendulum saw from a grinder

On the basis of an angle grinder, you can also make a pendulum and assembly cut-off saw for use at home. With its help, you can easily cut the same parts and blanks from wood and metal. The design of such homemade machine more secure, because the cutting disc, together with the grinder, is mounted above the countertop. Such a saw from a grinder is made by hand according to the drawings, and also with the experience and skills of a locksmith, it is performed by eye due to the simplicity of its design.

It is quite simple to make a pendulum or mounting saw from a grinder: the design will consist of a frame, a pendulum and a mount for the grinder. The frame can be made from profile pipes, welding a frame from them and installing a platform made of sheet metal with a thickness of 3 mm or more on it. A metal bracket is attached to the platform for mounting pendulum saw and a stop for fixing the workpiece during cutting. The emphasis is best done in the form of a rotating protractor, which will allow you to conveniently set the angle between the part and the saw blade.

It is also necessary to make a hole (cut) in the table top of the machine at the point where the saw blade touches. The pendulum in this design is also made of metal profiles by welding (you can see the drawings below on the page). It must be fixed on one side to the bracket, and on the other side, fix the mount for the angle grinder on it. This T-pendulum must have a movable joint to allow the cutting disc to move during operation. The connection can be made from a rolling bearing and bushing, as well as a rubber band or spring (to return the mechanism to its original position).

The fastening of the grinder to the pendulum is made in the form of a metal console with one or two brackets. To one of them, the angle grinder is attached with bolts, and with the help of the second bracket in the form of a clamp, the grinder is held by the body. A miter saw is made according to a similar principle, a video on the equipment of which you can see here.

Do-it-yourself chain saw from a grinder

The two previous types of home-made machines are good because, if necessary, the grinder can be dismantled and used in the usual way. Unlike them, for the manufacture of a chain saw from a grinder, it will have to be modified forever. You can also make a chain saw from a grinder with your own hands, but compared to the previous two types of machines hand made it is a less practical and less safe device. If you have an old grinder that you do not mind modifying for various cutting jobs, then you can make a chain saw out of it.

Such a saw may be needed on the farm for cutting branches and other wood structures where it is difficult to get with a conventional saw. To make a chain saw, you will need a bar mount bracket, which can be crafted from metal profile. The saw chain is pulled on it and the drive sprocket is wound on. It is advisable for such a design to choose a grinder with an adjustable speed of disk rotation.

Now you know how to make a pendulum, circular and chain type cutting machine from an angle grinder.

Circular electric saws - extremely necessary tools For household. Thanks to their technical and functional properties not a single one can do without them today furniture manufacturing or a carpentry shop. Yes, and in private households there are many tasks that would be more appropriate to solve with their participation. The only thing that limits their operation today is the cost, which grows every year, as does the need for them. One of the ways to overcome this barrier and acquire such versatile helpers is to assemble a homemade circular saw,

Given the load and cycle time of power saws, their home production will require an equally reliable basic electrical appliance. Craftsmen advise using a grinder or an angle grinder as it, which almost everyone has. Its traction potential will be enough for sawing wood, spreading bars into slats and other tasks that most users set for it. Consider several ways to make a power saw out of a grinder at home.

Do-it-yourself circular saw: the easiest way to make

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

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

An engine from a household grinder will act as the power base of the future construct.

Work progress step by step

from the grinder, the disk installed before is preliminarily dismantled;
a disk with teeth for woodworking is taken, which is pulled together by corners. A gap of several millimeters is left, which are regulated by a coupler of bolts;
the body of the grinder - the future electric saw is covered with clamps. At the bottom of the tool, a double metal tape with a thickness of at least 1.5 mm is passed;
grinder gear is pre-disassembled. It needs to make holes for fastening the handle. The last detail can be made of a metal tube, the shape of which should be slightly rounded;
to adjust the gaps between the side stop and the base surface, 4 holes are drilled in the gearbox for screwing in the bolts;
the handle is attached to the gearbox with bolts. Its end protruding from 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;
rods are cut into 6 cm blanks, which are given a loop-like shape;
washers are fixed in front of the stop, which corrects the gap;
the handle is attached to the body with an electric motor.

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

In both options, it is very important not to make a mistake with the choice of the disk and to correctly calculate the 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 output as a starting capacitor. In this option, you will need to consider additional grounding and check the electrical safety of the homemade product.

Chain saw from grinder: step by step instructions

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

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

The build process looks like this:

1. unscrew the saw blade from the grinder;
2. make holes in the lower part of the metal casing of the device;
3. bolts attach the bracket to the protective shield;

1. an asterisk is wound on the motor shaft;

a guide is fixed behind the bracket ties;
after the chain is put on and straightened, the bracket bolts are tightly fixed.

After that, you can get to work.

Advantages and disadvantages of homemade electric saws from grinders

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

a low level of safety for the health and life of the operator working - in homemade products there is no protection against recoil, 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 homemade saw in a container with chain oil;
high risk of overheating of the motor from the grinder due to overloads and prolonged operation.

The decision to make a circular from a small grinder is a great option in terms of savings Money. To design a sufficiently effective tool, the skills of a professional locksmith are not required. With a serious approach to business, you can cope with the task with the help of improvised tools and materials. Let's find out how to make a circular from a grinder?

Necessary materials and tools

How to make a circular grinder with your own hands? This will require the following tools:

actually the Bulgarian herself;
circular circle;
sheet metal (tin or galvanized);
a set of fasteners (bolts, nuts, etc.);
screwdrivers, pliers, wrenches;
electric drill with drills for metal;
metal corners.

Making a sliding stop

From the grinder requires the creation of a sliding stop. As the latter, it is most rational to use several that will be located on both sides of the saw blade. It is recommended that the lower edges of the specified structural element be rounded, which will not allow them to cling to surfaces that will be subject to processing with a home-made circular.

Corners must be fastened at both ends. To achieve optimal clearance, washers can be placed under the fastener heads.

Next, a metal clamp should be fixed on the body of the grinder, the screed of which should be located below. A strip of metal is threaded here, made of tin or galvanized folded several times. The ends of the latter are connected to the fasteners located at the ends of the previously assembled sliding stops.

Gearbox preparation

A circular grinder requires a working gearbox. The specified mechanism is extracted from the tool, after which the best places for drilling holes in metal. Such openings will be required to install the axial handle of a homemade circular. Naturally, you can try to hold the tool by the standard side grinder holder. However, the creation of even cuts in this case will become extremely problematic. As practice shows, holding a home-made tool with a rotating circular disk is beyond the power of even physically trained craftsmen.

Axial handle

To create an axial handle that will allow you to hold a homemade tool in a stable position, it is best to use a metal bar or tube. Holes are drilled at the ends of the workpiece, which will serve to attach the structural element to the grinder gearbox. The prepared axial handle is attached with fasteners to the mechanical part of the tool.

Adjusting rod

In order for a home-made circular from a grinder to allow you to adjust the depth of cut, a special rod must be provided in the design. Manufactured structural element from a steel bar with a diameter of about 4-6 mm. One end of the workpiece is bent in the form of a loop, splashed and fixed with the front bolts of the stop from the corners.

A thread is created on the tail of the bar, which will subsequently enter a special adjustment opening on the tool handle. Before installing the rod, one nut is put on its thread. After the tail of the element is threaded into the hole on the handle, the second nut is screwed on. Due to the tightening and loosening of these fasteners on the thread, the depth of cut is actually adjusted during the operation of the self-made circular.

How to make a stationary grinder?

The main difference between the design of handheld and stationary tools is the presence of a bed. Work is performed in the following sequence:

A special table is being prepared, which is covered with a galvanized or tin sheet. To fix the selected material on the plane, it is enough to pull it along the edges of the table with metal corners. The base on which the mechanical part of the tool will be installed must be as stable as possible. Otherwise, rocking will lead to inaccurate sawing of materials. In addition, table vibrations can be traumatic.
According to safety requirements, circular disk should not protrude a third of its diameter above the plane of the table. Therefore, in order to cut a wooden block with a thickness of about 10 cm, you will need a cutting wheel with a size of 35 cm or more.
A stationary circular grinder should be made on the basis of a sufficiently efficient engine. Here it is necessary to use an engine from a grinder with a power of at least 1 kW.
The basis of the adjustable stop will be a metal corner 7-8 cm long. The specified element is superimposed on the table and fixed with bolted connections.
A stationary circular grinder involves the creation of a shaft. The latter is recommended to be purchased ready-made, since critical errors may occur when it is turned on its own. You should choose a shaft that contains fasteners to securely fix the circular disk.
A V-belt pass will serve as a transmission.

If necessary, a do-it-yourself circular grinder can be made on the basis of a more powerful engine extracted from an old one. washing machine. In general, the choice of the engine here is limited only by the estimated power of the future instrument, which must be obtained at the output.

Safety measures when operating a homemade circular

Before starting a self-made circular saw, it is worth taking measures to avoid injury. If designed hand tool, the start button must be located away from the rotating blade. In the case of stationary saw the table on which the mechanical part is located must first be screwed to the floor.

When operating such a potentially dangerous device as a homemade circular saw, elementary vigilance must be observed. First of all, you should never line up with a spinning disc. After all, the latter can jump off the shaft when gaining critical speed. Also, do not bring your hands too close to it, which should be no closer than 20 cm from the cutting element.
