Option 3
This version of the device is the easiest to make with your own hands. It is made without the traditional pivot stand. All you need is one door canopy, a metal strip and a rubber band (you can use a rubber band from a hand expander).
The construction is done as follows:
- in the metal strip, on one side, drill holes for the door shed, and on the other, for the bolt, with which the strip will be attached to the angle grinder;
- screw an angle grinder and a canopy to the strip;
- screw the canopy to the table;
- attach one end of the elastic to the edge of the table and the other to the holder (handle) of the angle grinder.
In just a few minutes you will receive a quality cutting machine. This device is also mobile, because it can be carried with you in a suitcase with tools, and, if necessary, can be mounted on any flat surface.
When installing this device, do not forget to fix the corner on the table to rest the workpiece on it.
Pendulum cut-off machine
The platform for the machine is made of sheet steel. For the pendulum arm, a profile pipe is suitable, to which the transverse shaft is welded strictly perpendicularly. Two bearing assemblies are rigidly pressed onto this shaft at both ends. After that, the pendulum is welded.
Diagram of a pendulum-type metal cutting machine
A bracket is made of a steel strip for fastening the housing of the UShM gearbox. For fastening, holes are drilled along the edges and in the center. To ensure rigid fixation of the housing to the pendulum, a clamp is made from a steel bar. The metal clamping bar is fixed with bolts. The finished bracket, made in the form of the letter “P”, is attached to the console.
The bracket with a clamp and attachment for an angle grinder is welded to the pendulum arm, while the protective cover is installed. To automatically return the angle grinder to its original position, a return spring is used, which should be selected according to the weight of the angle grinder.
After the machine is assembled, it must be turned on and, at idle, check for vibrations, backlash. Then cut the groove for the cutting tool with a cutting wheel of maximum thickness. On the platform, the stops are bolted for the main directions of the saw. 45 ° and 90 °.
Features of using an angle grinder as a saw
It will not be superfluous for your safety to remind that not all types of discs can be directly used for an angle grinder. First of all, this concerns discs for sawing wood, which have significantly lower speed indicators than are used in almost all grinders.
The exception is special discs for wood, designed for standard rotational speed of angle grinders.
It’s good if your tool has speed control. And if not, then, before using your angle grinder as a miter saw for wood, make a simple regulator of its speed based on the KR1182PM1 microcircuit, or close to it in terms of indicators, according to this scheme.
It is not worth using a simple rheostat for this. Along with decreasing the RPM, it will also proportionally reduce the power and torque of the tool. And for the angle grinder itself, use in such operating modes is harmful.
We strongly recommend that you provide your stand with an emergency shutdown button, as the shutdown button can be difficult to access once the angle grinder is installed in the rack. And even an angle grinder securely fixed in the device. the tool is quite traumatic.
You can put such a button in the cut of its power wire, but it is better to break the supply electric line with it, because the angle grinder removed from the rack becomes an ordinary mobile tool with all its advantages.
Angle Grinder Stand Drawings
There are not so many drawings of such racks on the Internet. Basically, these are primitive sketches illustrating the principle of operation of the device rather than the exact dimensions and order of its assembly. And even those that exist do not have all the necessary information.
And the very design of such devices quite often raises doubts about the use of such a drawing without a certain correction.
Therefore, we advise you not to waste time looking for them, but after carefully considering the options for implemented projects to create homemade racks for an angle grinder, choose the one that suits you. Or, taking into account their shortcomings, implement your own.
The choice of material for the bed
In this case, the capabilities of the angle grinder are significantly expanded. By installing an angle grinder on a stationary structure, you can make a cutting machine that will accurately and at the desired angle cut any profiles. angles, I-beams, metal pipes.
To cut metal, wood, plastic sheets of large sizes, you should install the angle grinder on a moving carriage that moves along the guides. In this case, it is advisable to use metal corners as guides.
The angle grinder stand is available in a variety of designs. A variety of materials and assemblies can be used for its manufacture. It makes no sense to recommend any specific design, since each owner of the angle grinder will adapt the angle grinder to suit his requirements.
As raw materials for the device, you can use profiled pipes, as the most durable and reliable for this type of work. For guides, you can use corners, channels 5U or 6.5U.
For complex structures, you will need a welding machine, but it is easier to get by with screw connections. If the work does not require special precision, then the angle grinder can be used simply as a portable tool.
To perform precise work, for example, with a grinding attachment, you may need a stationary device. a stand for an angle grinder, an angle grinder (you can assemble a simple collapsible machine with your own hands, which, after use, will be folded and hidden in the space allocated for it). Such a frame is sometimes also made of wood. It is advisable to make a wooden frame if frequent and prolonged use of the angle grinder is not expected.
Do-it-yourself angle grinder stand. an overview of options
- securely attach the tool to the console;
- ensure minimal deviations from the cutting plane during operation;
- hold the tool securely in the upper position.
For attaching the angle grinder to the console, the threaded attachments of the handle on its head are suitable. There are 3 of them, and this is more than enough for reliable fixation.
And sometimes, to attach the angle grinder, they use a protective casing that is sufficiently rigid and securely attached to its head.
For small grinders working with discs up to 125. 150 mm, sometimes it will be sufficient to fasten the body to the console using powerful clamps, but to prevent axial rotation of the tool, the stop of the grinder head must be used.
angle grinder, working with cutting discs of large diameter (200. 230 mm), in addition to their reliable attachment to the console, must have a good support base for attaching the console itself to the work table.
This ensures the minimum deviation from the cutting plane.
Many DIYers provide the oscillating motion of the console by installing one or two bearings to attach it to the work table. For this, ready-made bearing assemblies for cars or bicycles are often used. However, a simple bolted connection will provide sufficient mobility, the parts of which, with good lubrication, will work as conventional plain bearings.
So, as shown in the video describing the simple design of the rack for an angle grinder made of metal:
True, we would not rely on such reliability of fixing the tool in the upper position, as the author of the video recommends, but would install the tension spring in a convenient place.
It is clear that the repair of such a console mount is reduced to replacing the bolt, or, in extreme cases, to simply increasing its diameter or installing a sleeve with a lot of wear of the mating parts.
A similar principle of ensuring compliance with the flatness of the cut is also ensured when the rack is made not from corners, but from shaped pipes. Watch a short video about a simple homemade metal drain for an angle grinder:
Few people decide to make a wooden stand for an angle grinder, but this does not mean at all that it cannot be done. But some of the design solutions that we want to show you may well serve as source of ideas for creating a rack of your own design, incl. and from this material.
To enlarge the picture. click on it:
Sometimes, to ensure the return of the tool to the upper position after the cut, instead of a tension spring, a conventional counterweight is used to compensate for the weight of the tool itself.
How to make the simplest rack for angle grinder with your own hands
Using the most common tools and using materials at hand, a simple do-it-yourself angle grinder stand can be made. To fix the angle grinder to the bed, you will need corners, metal or textolite plates. If two metal plates are used, the screws can be replaced with a welded joint. The plate serving as a mobile platform is made of steel sheet or duralumin up to five millimeters thick.
Homemade angle grinder stand
If textolite is used instead of a metal sheet, then the workpiece should be up to ten millimeters thick. The second plate must be metal, as it serves as a stop. For the manufacture, steel is used with a thickness of five millimeters, since the main load is applied precisely to it. Thinner metal cannot be used due to vibration and possible deformation, which makes working with the device unsafe.
For reliable fixation on the platform, several through holes with a diameter of five millimeters are drilled on one half of the plate. The second half of the plate is marked so that then a hole with a diameter of eight millimeters is drilled in the center of it. All holes drilled in the platform are reamed from the back for the heads of the countersunk screws. It is allowed to put a corner instead of the second plate, drilling it accordingly.
If welding cannot be used, the angle or plate is firmly screwed to the platform so that the distance from the edge of the device to the cutting wheel is at least five millimeters. In this case, the corner should be bent in relation to the rack by 60 °. To prevent the bolt from turning and vibration, the angle grinder is fixed in the upper part with a bolt with a Grover washer or a lock nut.

Materials and tools
The first question that a home craftsman faces when designing a stand for an angle grinder is what to make it from. The answer to this question is elementary: we will do what we have. If you have water pipes on hand, they will come in handy for making hinges and guides. If there is a metal corner, we will assemble a frame from it.
The main and most complex part of the pendulum saw is the hinge assembly. It carries the greatest loads, while the pendulum arm should not be able to freely deflect to the left or right. Consider the design of this node with the greatest care. Roller bearings are ideal. Pick a pair of suitable sizes. and already “around them” build the rest of the structure.
It is best to mount the pendulum arm on ball or roller bearings. This will provide the best precision and rigidity. But if there are no suitable finished products, it is quite possible to spy on the options for homemade designs of this unit.
If there are no ready-made bearings, match pairs of metal tubes and steel pins of suitable diameters. This will make it possible to make not too high-quality, but home-made bearings. For a “plywood” machine as a suspension of the pendulum arm, good canopy hinges used for fastening doors and gates will do.
In any case, the pendulum arm itself is best made from a metal corner or metal profile. But the holder, in which the angle grinder will be fixed, will probably be made of a wooden bar.
For a secure and tight fixation of the angle grinder in the holder, it is better to glue the stock with a soft and durable material. For example, leatherette. And it is most convenient to press the angle grinder to the holder with flexible metal ties with a screw assembly. These are widely used in plumbing and car service.
The bed is best made from a thick sheet of metal. Compromises are possible, up to thick plywood fixed to a timber frame. It is good to provide on the desktop the possibility of fixing the abutment corners at some standard angles to the cutting axis. Thus, we get a “miter saw”.
Do not forget that you will no longer be able to control the turning on of the angle grinder on the machine in the usual way. We can replace the operator’s hand on the control keys with the same screw ties for pipelines. But the keypad control post (which we will fix on the bed), a socket for connecting a fixed angle grinder to the circuit and a wire with a plug of sufficient length to connect the entire machine to the network should be saved.
If we have metal blanks at our disposal, it is best to connect them by welding. If you do not have such an opportunity, it is better to contact the familiar masters of this business. Bolted connections loosen over time and negate all the advantages of a metal frame.
Of course, the angle grinder itself will come in handy in the manufacture of the machine. Cutting with its help blanks for the rack, you can feel like Munchausen pulling himself out of the swamp by the pigtail.
Rectangular bed
Very stiff in itself, this profile allows for a rigid and sturdy frame. importantly, the pendulum arm made from this material will barely bend during operation.
But the bed frame is only half the battle. On top of the frame, you need to put a “tabletop”. a plate on which the processed material will be placed under an angle grinder.
If the frame is made of metal, sheet metal is the best material for the workbench. However, a thick sheet of plywood or chipboard is also fine. Just do not forget that a fairly wide slot must be provided in the tabletop directly under the disc of the angle grinder in the table top, which provides a through passage of the disc through the material to be cut.
The upright is a very busy pendulum saw unit. The use of a metal profile will create a strong and rigid structure.
When using metal as the basic element of the machine, preference should be given to welded joints. Of course, metal profile products can also be bolted together.
But such connections do not provide the required rigidity.
Carriage made of pipes and shock absorbers
If there are water pipes, a pair of car shock absorbers and a metal corner or profile in stocks, you can make a wonderful facing (aka “cutting”) machine with a transverse horizontal carriage feed.
Making a Homemade Angle Grinder Stand. El Yapımı Metal Kesme Standı. DIY
The pendulum unit is still required to bring the tool into the cutting plane. But the carriage, movable along the pendulum arm, allows you to significantly expand the range of material sizes. Now you can cut quickly and accurately not only pipes, profiles and beams.
The horizontal carriage travel allows you to neatly cut sheet materials as wide as we can design the carriage overhang.
Complex rail assemblies with spring-loaded bearings are usually designed to ensure smooth yet accurate carriage travel. But you can use car shock absorbers. They have a very robust and precise construction. If you remove gas and liquid, you get excellent guides.
The rear shock absorbers of VAZ cars have a stroke of almost 200 millimeters. This will allow, for example, when attaching an angle grinder-230 to a carriage, to organize a cutting line up to 400 mm long. But even if you have a compact angle grinder with a disc only 150 mm in diameter, you can still cut sheets up to 200 mm wide. This more than covers most everyday tasks.
When designing the “guide-carriage” assembly based on automobile shock absorbers, it should be taken into account that the shock absorber bodies themselves are quite thin and easily wrinkle. Such “guides” should be fastened to the upper arm of the pendulum with semicircular clamping brackets. This is where water pipes come in handy.
Plywood parts
An interesting solution to the problem of stiffness can be the use of plywood in a wooden structure. The multidirectional veneer layers in this material impart a certain dimensional stability to plywood products. The fact that the product consists of many thin layers, connected with a strong adhesive, provides strength.
Plywood is great for making beds and work tables. When designing, it should be borne in mind that plywood is very strong and stable in the plane of the product. But the plane itself can be deformed. Therefore, plywood products should be mounted on rigid frames.
A good example of a design is a multi-layer plywood assembly with intermediate bonding and bolting.
The result is very strong, rigid and stable structures.
Making a stand for an angle grinder with your own hands
Angle grinders (angle grinder) are an indispensable hand tool. With their help, you can saw, grind, cut almost any material from wood to stone. But often there are tasks that require the use of a machine park.
For example, when cutting pipes, a profile or a metal profile, it is quite common to cut a long string into segments of a certain length. In this case, it is important that the ends of the segments are strictly perpendicular to the axial mowing line.
When cutting tiles or bricks, it is even more difficult to keep the cut square by holding the angle grinder by hand. When cutting thin and sticky material, the slightest deviation of the tool from the mowing line of the cut can lead to jamming and breakage of the tool.
In such situations, it is quite natural to desire not to buy a separate machine. this, as a rule, is economically impractical.
You can expand the scope of your favorite hand tool by rigidly securing it in some way.
Elements made of wood
If it is not possible to make the basic elements of a pendulum saw from metal, do not despair. Many structural elements can be made from wood. First of all, this is the bed, pendulum arm and angle grinder holder.
The frame can be made from any suitable lumber. Frames made of solid and heavy timber of significant cross-section are very good. They are both durable and quite heavy. This ensures the stability of the entire machine.
The frame, assembled from an oak bar with a section of 100×100 mm, is certainly impressive. But it is too expensive. Thick bars of larch or even birch are quite suitable for the base of the desktop.
But for the manufacture of the pendulum arm, you can just use the noble types of wood traditionally used in furniture production. Oak would be quite appropriate here.
When constructing a machine from wood, do not forget about the overall rigidity of the structure. Significant dimensions of the bed make it possible to ensure the strength and rigidity of this part when manufactured from not the highest quality materials.
Making Angle stand For Grinder DIY
The pendulum arm has a long, elongated design. If made of wood, its geometry can be unstable with changes in temperature and humidity.
For this structural element, it is better to use the so-called furniture board, consisting of several wooden elements glued together.
Manufacturing options
Honestly, the do-it-yourself racks available in many designs should rather serve as food for thought. It is worth taking a closer look at the design, typical dimensions of standard elements and general design principles. Then apply them in our particular case.
The fact is that the dimensions of the structure and individual nodes will entirely depend on what you have at your fingertips. For a large angle grinder (eg 230 angle grinder), you may need to make a holder larger than shown in the drawing. This will entail the need to replace bearings and so on.
The general principles are clear enough. The simplest and most commonly used machine is the transformation of a hand-held angle grinder into a stationary pendulum saw. This design consists of a bed, a stand and a pendulum arm, which is hinged on the stand.
Consider manufacturing options depending on the materials available.
Homemade angle grinder stand. detailed manufacturing instructions
An angle grinder is a heavy tool that is difficult to hold in your hands at all times. Therefore, the masters try to fix it in such a way as to facilitate their work. A stand for an angle grinder, which you can make yourself, is ideal in this case. It is made quickly, and the cost is almost free in comparison with the work of a locksmith.
Rack with a carriage on shock absorbers
From pipes of circular cross-section and a pair of shock absorbers, you can make with your own hands not a simple stand for an angle grinder, but a cutting machine with a movable carriage in its mechanism.
Note! The pipes are useful for attaching the rails to the carriage without damaging the shock absorbers. they themselves are very fragile.
Moving horizontally, it allows you to cut material into longitudinal sheet plates. Shock absorbers can be replaced with a more complex rail structure with bearings.
The carriage is an important design element
Preparation: tools and materials
The do-it-yourself stand for an angle grinder is made of square-shaped metal pipes in section (wall thickness. 2 mm), to it are welded / screwed: a sheet of metal as a stand, bolts for fastening and a spring (for a counterweight). You will have to connect them using a welding machine.
If there are no pipes in the house, then hardwood will also work as a material, and welding can be replaced by drilling. In this case, you will additionally need: a grinder, an angle, a set of nuts and bolts with a drill. The wooden homemade angle grinder holder is convenient because it can be disassembled and reassembled.
Do-it-yourself angle grinder stand: drawings and projects
The drawing can be drawn independently, taking into account the dimensions and power of the product, as well as the attachment point. A stand for an angle grinder with your own hands is made on the basis of the options found on the Internet, but you should not copy them. it is better to consider photos of ready-made fasteners, and, starting from them, create your own project.
Important! The main tasks of the angle grinder holder include not only fixing the tool, but also keeping it in an upright position and setting the correct cutting angle.
Elements made of wood or plywood
However, if the stock of metal is not enough, wood or any wood-based materials will do the job. Even the lever, holder and other main elements can be made from wood, for example, from inexpensive birch or larch.
It is better to put plywood on the bed and base of the product, while making a frame of durable material that will keep it from deformation. The thickness of the material plays a key role in the strength of the structure: the thicker, the more durable.
Rectangular bed
Profile. the workpiece itself is very hard, so the frame made from it will not undergo deformation during operation. A plane is superimposed on top of the support frame: either a sheet of metal or plywood (Chipboard will also work). Wooden elements will have to be sanded.
Types of fasteners. briefly
Here are the mounting options offered by experts:
- With threaded fasteners and handle for operation.
- Full fixation of the mechanism inside the metal shell.
- Fastening the angle grinder with clamps on the bed. Suitable for models with a small disc (no more than 15 cm).
- Angle grinders and angle grinders with a wheel diameter of more than 20 cm must be secured with the axis of rotation, spring, frame and mounting guides. This ensures maximum reliability.
