25th September 2021

Models and their characteristics

In light of the large variety of racks for grinders available on the construction market from domestic and foreign manufacturers, it is worth considering the most demanded of them.

The simplest DIY solution

A simple attachment for an angle grinder can be made as follows:

As a base, take a 20 mm thick chipboard sheet and cut out two pieces of 500×400 mm in size.
The workpieces are combined and twisted together with self-tapping screws to make a plate 40 mm thick.
Take the narrow side and, stepping back from the edge in the middle at a distance of 100 mm, cut a 40×40 mm square with a jigsaw.
Take a steel profile pipe with a section of 40×40 mm and a length of 500 mm. One end of the pipe is smeared with epoxy glue and inserted into the square cut at the base.
When the post adheres well to the base, stepping back from the top of the pipe 100 mm, drill a through hole with a diameter of 8 mm parallel to the short side.
They take a section of a profile pipe 400 mm long and a section of 30×30 mm and, stepping back from the edge of 50 mm, drill a through hole with a diameter of 8 mm. this is a pendulum console.
The movable part is twisted with the stand so that it moves freely, but without backlash in the horizontal direction.
the angle grinder is fixed to the console using steel clamps. The handle of the angle grinder will serve as a control.

Counterweight design with shock absorber

An important part of the angle grinder bed is the counterweight. This structural element has a very specific function: it returns the angle grinder to its original position when the metal cutting operation is completed. If you do not provide a counterweight, it will be very difficult to work with an angle grinder. Before installing the workpiece, you will have to lift and hold it in your hands. You will also have to turn on the angle grinder by weight, which is unsafe. Counterweights come in two designs:

Traditional type. It is made by installing a weight on the tail of the cantilever bar. The weight of the load is selected in such a way that in the initial position the angle grinder is at the top, but when it is lowered onto the workpiece, no great efforts have to be applied.
Spring mechanism as counterweight. In this case, the angle grinder is held in the upper position by the spring force. The most suitable for these purposes is a spring for closing the door leaf.

A shock absorber or stop is also required in the design of the angle grinder stand. The main task of such an element is to prevent the tool from moving downward below a certain level. The moment the pipe is completely cut, the lowering of the angle grinder should stop.

The stop can be made rigid, for example, in the form of a metal stand with a rubber gasket at the point of contact with an angle grinder, or soft. it can be realized due to a small spring at the end.

Products of a universal sample, which can be jointly operated by the consumer not only with the grinders of this brand, but also with any other similar tool. The device works with cutting discs, the diameter of which varies from 125 mm to 230 mm.

With the stand, you can cut to a depth of 30-70 mm, with a cut width of 100 to 180 mm. Thanks to the work with the stand, you can work with material at an angle of 0 to 45 degrees. Depending on the modification, the rack can weigh from 2.9 kilograms to 5 kilograms. The manufacturer offers an auxiliary element with base dimensions: 185×235 mm, 285×277 mm, 336×350 mm.

Overview of possible options for manufacturing angle grinder stands

The angle grinder stand, as mentioned above, is a simple mechanism, but this statement applies only to the simplest designs. Having considered all the variety of factory-made devices and homemade products, three main types of devices can be distinguished:

the simplest pendulum bed;
pendulum mechanism with a rotary unit for cutting with an angle grinder at different angles;
bed for an angle grinder with a so-called broach.

The most common and easy-to-manufacture homemade angle grinder is built on the basis of a pendulum console. With the help of such equipment, you can easily saw various pipes of both round and profile sections, as well as rods, fittings and metal parts, the thickness of which does not exceed the thickness of the working part of the disk, and the length of the cut can be adjusted by moving the workpiece along the bed. Features of Attachment for Angle Grinder:

ease of manufacture and operation;
high reliability, since only one moving unit is used here;
such equipment will not be able to cut at an angle;
difficult to cut sheet material: low accuracy and injury risk.

The device of the bed with a swivel mechanism for an angle grinder allows you to carry out all the above-described metal cutting operations, but at the same time the function of sawing with an angle grinder at different angles is added. There is also a pendulum unit here, and, besides it, the pendulum support itself can rotate, or the stop-clamp, which holds the workpiece, rotates. Features of the device:

expanded possibilities of metal processing angle grinder;
relative simplicity of design;
here it is more difficult to obtain an accurate perpendicular and corner cuts due to the rotary mechanism and the need to calibrate the angle.

The broaching mechanism is the most difficult to execute. In addition to the pendulum unit, it uses a unit for pulling the angle grinder in the horizontal direction.

Bed drawings for angle grinder

The bed for an angle grinder can be of different designs, as shown in the drawings:

With upright column when the angle grinder is lifted off the base. This design has more convenient control and a larger length of the longitudinal cut.
No upright. here the hinge is formed straight from the base. This type of design is the simplest and allows the angle grinder to saw pipes of small diameter and cross-section.

Pendulum frame

A device for a pendulum angle grinder can be easily created with your own hands. Main structural elements:

Support or bed. the part from which the vertical stand departs and where the workpiece is laid for cutting. The supporting part also performs the main function of keeping the entire machine in a stable position.
A vertical fixed stand, or a tripod for an angle grinder. this structural element is part of the pendulum mechanism and a support for a movable arm.
Movable bar or console. a part to which the angle grinder is directly attached.

The support is mainly made of sheet metal. It can be a factory bed, for example, from a drilling machine or any other where there is a flat platform. On the bed for an angle grinder, there must be a guide, where the pipe is abutted during cutting. The guide does not allow the workpiece to move during the operation. In addition, for greater convenience, you can equip the support with a clamping mechanism that will motionlessly fix the pipe to the guide during operation.

A stand, or tripod, is a vertically going up element. It can be made from a shaped or round pipe. In the upper part, a bearing unit is attached for the movable connection of the rack with the pendulum arm of the angle grinder. The height of the tripod depends on the size of the angle grinder and the pendulum device. The type of pipe (its geometric parameters and wall thickness) is selected depending on the power and weight of the power tool.

The pendulum bar of the angle grinder has two functions. Firstly, it rigidly holds the angle grinder, thereby preventing the disc from moving in the axial direction. Secondly, with the help of it, the tool is fed into the processing area, that is, the angle grinder can be lowered into the working position, cut and returned to the starting position again. It also has a special handle to control the console.

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.

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 a stand for an angle grinder (angle grinder) with your own hands: drawings, constructive

One of the most popular power tools in the household is an angle grinder (angle grinder), commonly referred to as an angle grinder. Despite the fact that its main purpose is grinding, it is more often used as a tool for cutting various materials. This is primarily facilitated by the abundance of types of disks that can be installed on it.

The main disadvantage of the angle grinder when performing such work is the low cutting accuracy, because holding the angle grinder in your hands, it is extremely difficult to maintain the exact angle and direction of the cut. Rarely is it possible to cut off any material strictly at a given angle. Especially if you have to perform the workpiece of the same type of parts of any design, and even with the specified cutting angles. This disadvantage can be minimized by applying a special stand to the angle grinder.

There are such factory-made attachments for various models of angle grinder, some of them are quite versatile. But the relatively high cost makes them unaffordable for most DIYers. Meanwhile, most of these craftsmen are able to make a stand for their angle grinder with their own hands, without spending a lot of money, and even time.

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.

Troncatrice radiale DIY (Sliding angle grinder stand)

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.

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.

The simplest attachment for a rack angle grinder

Actually, this device cannot be called a stand, and you can do almost the same work with it, which is provided by the most technologically advanced stand. The principle of its operation is clear from a short video:

But if, instead of a strip, you use a corresponding corner with a sawn-off part of one of the shelves, as one of the authors of a similar design did, then there will be no need to drill a blind hole in the head of an angle grinder.

In this case, the tool will be fastened with two screws into the threaded holes for the handle existing on the head of the angle grinder. And the principle of the sole will not change. only its rigidity will increase.

Stand for cutting sheet steel

Grinder machines, which can cut sheet material from steel, are much more complicated than conventional pendulum machines. The main difficulty here lies in the fact that the sheet of metal has certain linear dimensions and throughout the entire mowing line it is necessary to keep the cutting evenness. Another difficulty here can be considered the effect of heating the cutting area, in which the metal expands and clamps the disc of the angle grinder in the channel, which is fraught with jamming and rupture of the tool with all the ensuing consequences.

Base. Ideally, it should be no less than the sheet that is supposed to be cut with an angle grinder, or allow the entire cutting area to be laid on it. It is necessary to use steel as a material for manufacturing so that it absorbs heat, preventing overheating of the mowing line for cutting steel.
U-shaped rack. This structural element serves as a guide for extending the angle grinder. The length of the segment between the legs of the stand should be sufficient to put a sheet between them, plus allow the body of the angle grinder to fit freely.
The carriage is a movable element that moves along the U-shaped rack on bearings. A pendulum arm and a depth limiter for lowering the cutting disc are attached to it.
The pendulum arm serves as a mechanism for lowering the angle grinder to the level of the working position. It also has a tool control knob attached to it.

You need to pull the angle grinder in the opposite direction to the direction of the sparks, otherwise the tool will undermine with a high probability of jamming.

Pros and cons

For an objective understanding of the functionality of the racks for the “angle grinder”, you should consider their positive features.

In the course of work, you can accurately position the workpiece on the fixture. This detail is important for very precise cuts on hard and soft materials.
During operation of an angle grinder on a universal bed, the risk of injury hazardous situations is reduced, since the fixed tool will work with precise movements of the cutting element.
If you use the rack for all sorts of construction, production or repair issues, you can increase productivity and speed of solving work tasks.
If you install and fix a workpiece or structure made of wood or other material, then the quality of operations with the object will significantly increase.
Angle grinder stands for metal cutting allow the operator to position the workpiece at the desired angle. This can be done quickly and accurately. A vice will be very useful in this case.
The bed makes it possible to work with any type of raw material.
Most of the platforms allow you to fix the working element not only horizontally, but also vertically. A similar positive feature is relevant for prefabricated structures, with which the master performs manipulations without preliminary disassembly.
The work of the master is greatly facilitated, since the material will be securely fixed on the device, and it will not be necessary to hold it.
Racks can be used in a small workshop and in everyday life. There is also the possibility of creating homemade auxiliary elements.

However, this mechanism also has some disadvantages:

The angle grinder belongs to the category of tools that have a high degree of risk of injury. This is due to the fact that the saw blade of the angle grinder rotates at high speeds, and the probability of it jamming in the workpiece is very high. This is especially true for long longitudinal cuts, when the abrasive tool is clamped when the metal is heated. When cutting pipes, the section to be removed can compress the cutting disc. this leads to a rupture of the body of the blade. To avoid the negative consequences of working with an angle grinder, an angle grinder stand is used.

When the angle grinder is rigidly fixed and moves only along a predetermined path, observing a certain cutting angle, the likelihood of danger decreases significantly. Angle grinder stands are commercially available, but this is not such a complex mechanism that you need to buy.

For your tool, you can make a simple device with your own hands. it will come out cheaper, and a self-developed design for a specific model will always be more accurately adjusted.

INTERTOOL ST-0002

Multifunctional stand, which is compatible with grinders with a disc diameter from 115 mm to 125 mm. Suitable for household use. The device facilitates the work of the master, has a reliable fastening, therefore it is used to perform serial work with materials of various types. Rack cuts can be cut from 0 to 45 degrees.

The stand is designed to work with discs with a diameter of 115 and 150 mm. The model has a protective cover and a solid base with a clamping system for working materials. The products have small dimensions, and the base of the rack itself is made in the shape of a square, which makes it easier to maintain.

Selection Tips

In the course of selecting an accessory for the “angle grinder”, you should first of all decide on the question of the compatibility of the rack with the diameter of the discs that the angle grinder works with. It is important that the entire rack structure is fully compatible with the existing cutting and grinding tool. Therefore, you can go shopping together with the operated unit. As practice shows, pendulum struts are especially effective when working with ceramics, wood or metal, with which you can implement a wide range of tasks, in addition, they are quite simple in design and operation.
