Homemade rack for earmuffs. How to make a stand for a grinder with your own hands in different ways? Homemade stand for an angle grinder grinder

One of the most popular power tools in the household is an angle grinder (angle grinder), commonly referred to as a 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 varieties of disks that can be installed on it.

The main drawback of the grinder when performing such work is not the high accuracy of the cut, because holding the angle grinder in your hands is extremely difficult to maintain the exact angle and direction of the cut. It is rarely possible to trim any material strictly at a given angle. Especially if you have to perform the preparation of the same type of parts of any design, and even with specified cutting angles. This disadvantage can be minimized by applying to the grinder special stand.

There are such factory-made fixtures for various models of angle grinders, some of them are quite universal. But the relatively high cost makes them out of reach for most home craftsmen. 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 time on it.

Drawings of a stand for a grinder

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 are, do not have all the necessary information.

And the design of such devices itself quite often raises doubts about the use of such a drawing without some correction.

Therefore, we advise you not to waste time looking for them, but after carefully considering the options for implemented projects to create home-made racks for angle grinders, choose the one that suits you. Or, taking into account their shortcomings, implement your own.

Do-it-yourself stand for a grinder - an overview of options

The main tasks of this rack:

securely mount the instrument on the console;
ensure minimal deviations from the cut plane during operation;
securely hold the tool in the up position.

For fixing the grinder on the console, the threaded fasteners of the handle on its head are suitable. There are 3 of them, and this is more than enough for reliable fixation.

Sometimes not everyone uses them.

And sometimes, for fixing the angle grinder, they use a rather rigid and securely fixed protective cover on its head.

For small angle grinders working with discs up to 125 - 150 mm, sometimes it will be sufficient to fasten the case to the console with powerful clamps, but to prevent axial rotation of the tool, the stop pad of the grinder head must be used.

Angle grinders working with cutting discs of large diameter (200 - 230 mm), in addition to securely attaching them to the console, must have a good support base for attaching the console itself to the desktop.

This ensures minimal deviation from the plane of the cut.

Many do-it-yourselfers provide the oscillatory movement of the console by installing one or two bearings for attaching it to the desktop. For this, ready-made bearing assemblies of cars or bicycles are often used. However, a simple bolted connection will also provide sufficient mobility, the parts of which, with good lubrication, will work as conventional plain bearings.

As shown in the video describing the simple design of the metal angle grinder rack:

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 comes down to replacing the bolt, or, in extreme cases, to simply increasing its diameter or installing a bushing with a lot of wear on the mating parts.

A similar principle of ensuring compliance with the flatness of the cut is also ensured in the manufacture of the rack not from corners, but from shaped pipes. Watch a short video about a simple homemade metal drain for angle grinders:

Few people dare to make a wooden stand for a grinder, but this does not mean at all that it cannot be done. And here are some design solutions that we want to show you, it may well serve as a source of ideas for you to create a rack of your own design, incl. and from this material.

Sometimes, to ensure that the tool returns 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.

Features of using an angle grinder as a saw

It will not be superfluous for your safety to recall 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 speeds than are used in almost all angle grinders.

The exception is special discs for wood, designed for standard speeds 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 speed controller based on the KR1182PM1 chip, or close to it in terms of performance, according to this scheme.

You should not use a simple rheostat for this. Along with the reduction in RPM, it will also proportionally reduce the power and torque of the tool. And for the angle grinder itself, use in such modes of operation is harmful.

It is strongly recommended to secure your rack emergency stop button tool, because access to the shutdown button after installing the angle grinder in the rack can be difficult. And even securely fixed in the angle grinder fixture, 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 line with it, because the grinder removed from the rack becomes an ordinary mobile tool with all its advantages.

The simplest attachment for the angle grinder rack

Actually, this device cannot be called a stand, and work with it can be done almost the same as that 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 an appropriate 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 the angle grinder.

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

The way to use the grinder as a kind of circular saw using the same sole, shown in another video by the same author, will not change either:

Dear readers, if you still have questions, ask them using the form below. We will be glad to communicate with you;)

The universal hand grinder - the well-known grinder (the first samples of which from the Bulgarian company Sparky appeared almost 50 years ago) was conceived as a portable drive device for various machining operations. However, as the production capabilities of the tool improved, it became clear that in some cases the angle grinder needed a reliable support. Buy a ready-made bed for a grinder or make it yourself? Today, we will examine this issue.

Industrial frame structures

A bed for an angle grinder will be required in the following cases:

Cutting / grinding of a structure made of difficult-to-cut material, or with a large surface area.
Higher cutting accuracy is required.
It is necessary to process several products with the same parameters.
The workpiece material is discontinuous in cross section, and the presence of voids and shells can provoke vibration, shock and, consequently, a sharp movement of the machine body.

The frame for the grinder is produced by almost the same companies that produce the tool itself. The price for the simplest design, depending on its manufacturer, does not exceed 2,500 ... In addition, such racks are not particularly versatile, and, of course, do not take into account the individual needs of the user.

Such beds consist of the following elements:

The base plate, which is made of thick steel sheet and is equipped with T-slots for fastening the workpiece. Maybe a cast iron stove;
The rack itself, on which a mounting device is provided for the angle grinder of a specific model;
Adjusting devices that allow you to rotate the rack itself, as well as change the location of the angle grinder vertically;
Optional: clamps or clamps for the workpiece, the dimensions of which are unified with T-slots. Sometimes the kit additionally includes a bench vise with a set of profiled stands;
Rotary handle, with the help of which the working movement of the grinder itself is carried out;
Measuring devices, often an angular or regular ruler;
In especially advanced models, there is also a return mechanism with a spring.

Positive features are the possibility of clean cutting of pipes from round profiles, which is problematic and even dangerous without a stable clamping of the workpiece. The frame for the grinder is also necessary for corner cuts of any profile.

The technical capabilities of these devices depend on the area of the supporting surface of the plate and the height of the angle grinder in the frame. Usually, the parameters are calculated for a grinder disk with a diameter of up to 250 mm, and for the dimensions of the fixed part of the workpiece no more than 100 ... 150 mm.

We design our own version of the bed for the grinder

Taking as a basis the above completeness of the frame for the grinder, everyone will be able to modify the design to suit their needs. Moreover, many of the details of a home-made device can be used from other mechanisms. For example, the base of a desktop drilling machine or a decommissioned plate from a small universal assembly device (USP), which already have T-slots, is quite suitable as a support frame.

The work includes the following stages:

Development of technical specifications and drawings. The main parameters of a home-made bed for an angle grinder will be the maximum diameter of the working disk, the dimensions of the angle grinder itself and the largest section of the workpiece with which to work.
Selection of blanks for the manufacture of the frame. This takes into account the dimensions of the section of the parts, and the material from which they are made. For example, the welded version is less reliable due to periodically occurring vibrations and dynamic loads, therefore, low-carbon steels are preferable to steels such as St.5, steel 45, etc., whose mechanical strength is higher. For the same reasons, tubular profiles are more appropriate than corners or I-beams.
Making a fixture, relying mainly on its own capabilities (although a number of parts, in particular, for measuring dimensions, fastening elements for angle grinders on a rack, etc., are best ordered in professional workshops).
Finishing (stability check, painting, possibly heat treatment), as well as installation of the control system.

At the same time, it is necessary to provide for the possibilities of the frame for the angle grinder for the future, i.e., the suitability of the device for performing other operations with it, for which any angle grinder is intended.

Further questions will be considered on the assumption that all components of the bed will be manufactured from scratch. For example, the following construction can be taken as a basis (see Fig. 1).

Figure 1 - General view of the frame assembly

From fig. 1 it follows that the bed of this design consists of:

A support frame that can later be installed on a workbench or any flat surface. The frame is welded from shaped pipes with increased rigidity, including during vibrations.
Round universal fixture with 8 mm grooves, on which products weighing up to 12 kg can be installed. The USP is equipped with a rotary table with a screw control mechanism - a handwheel and a reading dial. As a turntable, you can use a hub from any passenger car that fits in size.
Table made of thick-rolled steel with mounting holes.
Locksmith vise for the workpiece to be processed (installed on the cantilever to balance the overturning moment from the USP).
A vertical rack welded to the frame, to which the grinder itself is attached.
return mechanism.
Swivel arm with tool holders.

The turntable itself is supplied with a ruler, which should count the angular and linear movements. Its location is clear from Fig.2. Instead of the factory design of the reference ruler according to the drawings, you can also make a home-made one using a set of two ordinary locksmith rulers and an angle meter. For less complex work, and is suitable.

Figure 2 - View of the desktop in the installation position

When making a desktop with your own hands, it is necessary to provide for radius rounding of the corners and the ability to move a bench vise without violating the overall alignment.

Manufacture of the main components of the bed

The greatest technical difficulty is the manufacture of the rotary lever. It should provide reliable clamping and fixation of the angle grinder, its rotation at an angle of up to 90º, as well as the return of the grinder when the load is removed from the rotary handle.

The design of the swivel arm, designed for mounting on the rack, is shown in Fig.3.

Figure 3 - View of the frame from the side of the rotary arm

The swivel arm includes a vertical post, which is rigidly fixed to the base plate, a console with an axle and a bearing assembly (with their help, the grinder will be rotated), a clamping device and return springs located on the opposite side of the console.

In order to securely fasten the angle grinder to the considered design of the frame for the angle grinder, several solutions can be used:

An open prism, welded from corners, the opposite sides of which are compressed by a clamp;
Steel ladders with which the tool will be wrapped around in the required section;
Bolted fixation with the help of two bolts with a persistent thread, which are placed on both planes of the corners, and provide a clamp for the "grinder" by rotating the high nuts GOST 5931, as shown in fig. 4.

Obviously, in the latter case, the ease of installation and centering of the angle grinder will be the best (the option with a clamp will be very difficult, and the ladders can be unstopped during prolonged vibration loads).

Figure 4 - Attachment of the "grinder" to the swing arm

The final stage in the manufacture of a home-made bed for an angle grinder is the installation of elements to turn the unit on / off. Experts advise not only to provide remote shutdown of the angle grinder, but also to install a foot pedal for this, since the hands of the worker are busy, and a sudden problem with cutting or grinding is fraught with injury to the worker. To do this, the control of the device is provided through a magnetic starter.

The assembled structure of the frame for the grinder is first tested with the manual rotation of the disk. The purpose of the check is to find out the source of possible beats of the device if an error is made in its centering. Then the angle grinder is turned on at minimum speed, and if vibration does not occur during long-term operation, it is possible to check when cutting a wooden and then a steel workpiece.

From a safety point of view, it is better if the frame for the angle grinder is partially covered with a removable casing, which can be made of high-impact plastic.

Videos of exploited varieties of home-made beds are presented on the Internet in a wide variety. One of them is below.

An angle grinder or grinder makes life easier at work and at home. With its help, you can file an acute angle, cut off the protruding part of a profile or pipe, make a hole in a tile, etc. It is inconvenient to keep the tool in your hands all the time. Hands get tired, and the cut is uneven. To make your work easier, here are some homemade options for cutting machines with a holder and a bed that can be made from scrap metal.

Bed for angle grinder from profiled pipes and shock absorbers

The grinder is a rather heavy and powerful tool, so the frame for holding it suspended must be strong. Profiled metal pipes provide such strength. The manufacture of a holder for a grinder made of wood is only allowed from thick lumber. However, even in this case, it is impossible to guarantee that the structure will withstand the load. When working with profiled metal pipes, you will need a welding machine and equipment skills. In addition to the grinder and welding machine, also prepare for work:

two rear used shock absorbers from the car;
pipes suitable for the diameter of the shock absorbers for crimping;
profile pipes and metal square corners 25 mm for collecting the base;
two brands 35 × 25 mm to stiffen the base;
two corners 40 mm for vertical supports;
metal plates for fixing shock absorbers 190 × 75 × 5 mm;
square corner 45 mm L = 120 mm for connecting the angle grinder with shock absorbers;
automotive nuts and bolts 12 mm for tightening the plates.

Before starting work, we are working on a drawing of the future frame. To make it easier for you to do this and avoid typical mistakes in the manufacture of the structure, we recommend that you familiarize yourself with the analogue in the store. Inspect the bolt fasteners, the location of the supporting elements and other details. It is advisable to be guided by the principle of assembling the frame specifically for your angle grinder model. After familiarization, it remains to transfer the dimensions and make a drawing on paper.

A distinctive feature of this design is the extension of the holder. As a result, we will get an improved version of the pendulum saw with the ability to adjust the holder not only up and down, but also forward. To bring this idea to life, you need a couple of old car shock absorbers.

Since the walls of the shock absorbers are thin, and they will bear the main weight of the structure, it is necessary to give them strength. To do this, take a pipe of a suitable diameter and cut the crimps. In metal plates, we drill holes of a suitable diameter for tightening the holders with automotive bolts, weld cut pipe swages to them.

We proceed to the assembly of the base. Its dimensions are 46.5 × 40 cm. In order not to spend money on buying new pipes and corners, we will use scrap metal, anyway, after assembly, the parts will be painted. The back of the base consists of two squares 25x25 mm, and the front of one. Two corners of the same section are welded on the sides. With an indent of 10 mm from the side parts, we fix the tees 35 × 25 mm. To the back of the base we weld two 40 mm corner-racks 32.5 cm long at a distance of 9.2 cm from each other. From the inside of the vertical corners, we drill holes for mounting the holders. We connect the racks to each other with a plate, which is welded to the right angles of the supports.

The case is made, we begin to assemble the machine. First we fix everything on the wire. We check the correct assembly of the structure, the quality of the cut and, if necessary, adjust. If everything suits you, you can move on.

For the convenience of adjusting the stroke of the holder forward, we cut out a corner of a suitable length (in the photo) and make the appropriate holes in it. Departure at the ends of the shock absorbers is fixed with a threaded stud and nuts.

To fasten the angle grinder, we make a fastener, the parts of which are welded together. It is fixed on threaded fasteners, it is easy to remove and replace if necessary, change the diameter of the disc. Dimensions are selected individually according to the angle grinder model. The finished part is attached to the outside of the shock absorber corner.

After turning, all parts are painted. To keep the position of the holder with the tool in a horizontal position, in addition to the upper compression of the shock absorber and the frame, we attach fasteners for a stud with a diameter of 8 mm. The return movement of the pendulum is provided by a door spring, which can be purchased at a hardware store.

We left gaps of 1 cm between the side corners and the brands for a reason. We need this space to move the desktop. Given the width of the corners and the gap, we make holes on the sides of the table for the adjusting bolts. We paint and attach the table to the base. If you need to move the work surface, slightly unscrew the bolts and change the position of the table forward or backward. Additionally, for the convenience of cutting metal, we recommend making guides at 90 and 45 degrees.

Cutting machine with a pendulum lever from a transverse shaft

To assemble the frame part and the pendulum holder, you will need shaped pipes, and for the cantilever mounting, you will additionally need steel strips and a metal rod. The stand, which will also serve as a working platform, is made of steel sheet. We weld the transverse shaft to the pendulum lever from a section of the profile pipe, observing the perpendicular when fastening. As bearings that will ensure the rotation of the pendulum, we use ready-made bearing assemblies. We press them on the shaft from both sides. The connection must be rigid, otherwise unexpected longitudinal or transverse displacement may occur. When the bearings are pressed in, we retreat 5–6 cm from the edge of the stand, weld the assembled pendulum with the support nodes.

We make a U-shaped bracket from a steel strip. This will be the bracket that holds the gear housing of the angle grinder. To fix the case, we drill holes in it for bolts on the sides and in the middle. We bend a horseshoe-shaped clamp from a steel bar and make a clamping bar for fixing the tool body to the pendulum. It is a metal plate 1.5–2 cm longer than the clamp width. We insert threaded fasteners into the holes along the edges of the pressure plate, fixing them with nuts. We try on a ready-made U-shaped bracket and a clamp for a grinder. Using welding or threaded connections, we fasten the parts to the console.

We weld a console with a clamp and a U-shaped fastening of the grinder onto the pendulum lever, choosing the appropriate position for the tool. There are different opinions about how to fix the grinder - from yourself or on yourself. Considering that medium or small angle grinders are used for domestic needs, we install the rotation disk "from ourselves". This will give you better control over the precision of the cut. Be sure to secure the protective cover for safety reasons. According to the weight of the grinder, we select a suitable return spring. After assembling the machine, we test it. We do the first check in idle mode. There should be no vibration, extraneous noise and play. If there are problems, we fix them. Next, take a cutting wheel with the maximum thickness that you use for work, and cut a groove for the disc with the machine. If necessary, the gap can always be widened.

The final stage is the installation of an emphasis for metal and wooden blanks. As a rule, two main stops are installed - for washing down at 45 and 90 degrees. The strips can be welded, but it is better to fix them on a threaded connection. Such structures are easily removed and changed. An additional detail that will facilitate your work will also be a limiter with a measuring ruler. It is enough to fix a metal ruler on the stop and the process of measuring and cutting workpieces to the nearest millimeter will never be a problem for you.

Then your imagination works. You can also equip the machine with protractors, vices and clamps. These grinder tools allow you to make a cut or groove in the workpiece at any angle. At the end, don't forget to paint the machine so that it has a finished look and is protected from the "web of rust".

The simplest rack with a holder from a water pipe and corners

If the previous ideas of racks for angle grinders seemed too complicated for you, we offer you another maximally simplified, but no less convenient option. For its manufacture, you will need corners of different sizes, a water pipe, metal scraps, as well as bolts and nuts for fasteners. Let's start with the platform. Its size is selected individually according to the complexity of your work and the dimensions of the workpieces. In our example, the dimensions of the metal platform are 40 × 27 cm. To give it rigidity and prevent slipping, we fasten it to the table at the corners with self-tapping screws, and also strengthen the stand by welding the corners under it.

To attach the holder to the platform, we fix a corner 50 × 50 mm, equal to the width of the stand. We weld another corner of the same section 17 cm high to it in a vertical position.

After that, we move on to the holder itself. We find an old water or other pipe with a diameter of about 25 mm, measuring its length in accordance with the dimensions of the platform and grinder. To fix the cutting wheel on it along with the tools themselves, we weld two metal plates 5 cm wide and 9.5 cm long to the holder. We weld a nut on the edge of the pipe for attaching the side handle, which must be removed from the grinder. So it will be more convenient for you to lower and raise the rack.

Separately, I would like to talk about another fastening of the holder to the vertical corner. To form a plane, we also weld a piece of a 30 × 30 mm corner to the corner-stand and the pipe. We attach the mobility and reliability of the connection of the holder with the frame in this part due to the M-8 bolt, clamping it from the back side with a nut and a lock nut. When raising and lowering the structure in this part of the rack, the bolt is clamped and firmly fixes the selected position of the angle grinder.

The protective casing of the angle grinder is quite rigid, which allows you to make fasteners in it. On one part we fix the plates with bolts, and on the other, we make an additional attachment point for the bracket, screwing it to the place where the handle was removed. We cut the bracket 4 cm wide and 16 cm long with a small angular bevel, also about 4 cm.

The main part of the rack is assembled, it remains to take care of the convenience of work. As in the previous versions, we fasten the stop from the corner 50 × 50 mm to the platform. For better visibility during the cut, a small upper part of the corner can be cut off from the edge. Now it will be convenient for you to clamp the workpiece with a clamp and make an even cut. Also, do not forget to paint the machine or cover the metal with enamel to enhance its aesthetic appearance and extend the period of operation.

The well-known angle grinder, with its cutting, grinding and cleaning capabilities, has proved capable of several more functions. Expanding the functionality requires doing some work with your own hands in order to get the tools you need for the job.

This attachment is a small machine that can easily, safely and very accurately cut metal pipes, profiles or rods. It consists of a base or a small table attached to the ground or to a locksmith's table.

The machine is assembled in a simple sequence:

install a hinge on the base;
we weld the carrier pipe to the hinge;
we attach to the pipe P - a figurative plate for fastening the grinder;
we put a rubber handle on the carrier pipe;
install the disk and check its position.

As a result of simple work, we got a machine or stand for a grinder. Now the angle grinder can rise and fall on the hinge on the part installed for cutting. In order for the grinder to rise without loads, we install a spring on the pipe.

Two fixing corners must be installed on the table. At the base of one corner, we make a groove for the bolt around the circumference. It will be needed when a pipe or profile needs to be cut at a certain angle. Then we install this corner with a slot at the same angle to the plane of the cutting disc of the grinder.

Parallel to the corner with an arc slot, we install a corner that can be moved to the part to fix it on the table. The pipe or profile will simply be nested between two corners. This is enough to perform a fast and accurate cut.

By installing a supporting transverse metal bar on the machine table, you can clean the material with a steel brush mounted on the grinder shaft.

Simple cutting machine + (Video)

A cutting machine based on an angle grinder can be made by hand in one day. For the machine, it is necessary to choose a frame - a metal base plate. Attach a hinge to it. Weld a supporting frame with a plate for attaching the grinder to the hinge.

Any suitable part can be used as a hinge. In this case, the hinge is made from the swivel joints of a passenger car. The hinges have already served their time, but they approached the machine very well.

Do-it-yourself wall chaser from a grinder + (Video)

A strobe is a groove that must be cut in the wall for laying electrical wire or cable. The complexity of this work lies in the fact that the groove must be of constant width and depth. Then the wire will be laid evenly and less mortar will be required for laying.

A wall chaser is rarely used in practice, so it will be expensive to buy it for a home. But it can be made on the basis of an angle grinder - our favorite grinder.

The main task is to install two diamond discs on the grinder shaft with a distance of at least 1 cm:

install the first disk and fix it with a nut;
install the second disk and fix it with a nut;
measure the resulting distance between the disks;
install protection on the grinder;
checking the work.

But, if for some reason it is not possible to install two disks on the shaft, the strobe can also be cut using the usual method with one installed disk. You just have to cut the second parallel line.

Work with a wall chaser is carried out indoors. This creates a huge amount of dust. Not even a respirator can save her. To eliminate this negative phenomenon, it is necessary to make a protective casing that would cover both disks and have a pipe on top for connecting to a vacuum cleaner. A similar device is on electric jigsaws for collecting small sawdust.
Sometimes lovers of the rational use of the tool fit 2 or 4 rotating rollers to this casing. When the wall chaser moves along the wall surface, it will move on rollers, without creating additional loads on the hands.

To manufacture a tool for a wide groove, it is necessary to make special bushings for mounting discs to the desired width. With such a wall chaser, it will be possible to make grooves for laying pipes.

But the protective cover will also need to be made wider. On the casing of the wall chaser for both wires and pipes, it is necessary to install a screw for adjusting the immersion of the cutting tool into the wall. In this case, the casing will consist of two parts connected by a hinge and an immersion adjustment unit.

Milling cutter from grinder + (Video)

Sometimes it becomes necessary to mill a hole or a surface, but there is no familiar milling machine, and there is nowhere to look. But there is an angle grinder - a grinder. This is the solution to the problem. We choose a machine from two options - a movable machine and a movable table.

In the first case, we fix the workpiece or material to be milled, and the grinder is attached in a vertical plane to the frame. On the frame, it is possible to move the plate to which the angle grinder is attached to the left - right and forward - back. In other words, we can move the grinder relative to the workpiece.

In another version, the grinder is fixed rigidly, and the workpiece moves by analogy to the left - to the right and forward - back. These are the main directions for milling. For milling along the up and down axes, it will not be difficult to supplement the adaptor.

Having chosen the option of the machine, you can begin to implement. The only place that will require the involvement of a turner is the cutter holder. It is machined from a hexagon of at least 16 mm, because the grinder thread is 14 mm. Collet type holder. It is easy to manufacture and does not have large beats. A conventional cam chuck does worse.

The advantage of such a machine, as well as all machines based on the grinder, is that they are easily transformed back into the grinder. As a kind of milling cutter from a grinder, you can make a drill.

Pendulum Saw + (Video)

It is not difficult to make tools for a grinder with your own hands. It doesn't even need blueprints. It is enough to know the principle that is embedded in a particular machine. A pendulum saw based on a grinder is no exception. This is the same cutting machine, but its weight is distributed almost in half.

It is somewhat similar to a children's swing. A frame is located on the movable sleeve, and an angle grinder is installed on it. Any load in combination with a return spring can serve as a counterweight.

The capabilities of the grinder can be expanded not only through various nozzles, but also by installing it on special home-made devices. As a result, you can get a cutting machine, with which it becomes possible to accurately cut metal blanks at any angle. In addition, the grinder can be installed on a carriage, and the resulting machine can be used for cutting sheet steel.

In order to understand how to make a cutting machine out of an angle grinder (angle grinder), you can look at various drawings on the Internet. But they will not help much, since all the dimensions of the parts will still have to be selected based on the size of the grinder you have. Options for the execution of devices can be both simple and more complex, requiring the ability to handle a welding machine.

Option 1

To make this device for the grinder, you will need welder skills. So, you need to do the following.

First, cut 2 small pieces from the corner (50x50 mm). Their size is selected based on the dimensions of the gearbox block of your angle grinder.

Next, drill holes in them with a diameter of 14 mm and screw the corners to the angle grinder, as shown in the next photo. If you do not have suitable bolts, then you can use threaded studs M14. Just be careful that the bolts are not too long. Otherwise, in some models of angle grinders, they can cling to the impeller located in the gearbox housing.

Without removing the corners from the grinder, grab them by welding. After that, the corners can be removed and scalded well.

Clean the welds with a grinder grinder.

Then you need to make rotating arm support to which the machine will be attached. To do this, select 2 pipes of such diameters that one can easily enter the other without much effort.

For a more accurate cut, masking tape can be glued to the tubes and draw a line on it.

Then, turning the tube, carefully cut it with an angle grinder. A piece of pipe of a smaller diameter should be shorter by 20 mm (thickness of 2 bearings) - it will serve as a spacer.

Choose 2 bearings suitable for its inner diameter for a thicker pipe. After that, insert a thin tube into a thick one and press the bearings on both sides.

Then insert the stud into the bearings. Be sure to put a washer in front of the nut.

When the swivel mechanism is ready, you need to weld a small piece of the corner to it.

The next step is to swivel stand from the same corner 50x50 mm. To make the segments the same length, the corners can be pulled together with a clamp and cut off.

Also, without unwinding the clamp, they can be drilled immediately.

Attach the drilled corners to the prefabricated swivel block with nuts.

Weld a longer corner to this rack, as shown in the following photos.

Now you need to decide on lever length, on which the angle grinder will be fixed. This is done by selection, based on the dimensions of your grinder. You can lay out the details on the table and calculate the approximate dimensions of the lever, which is best made from 2 pieces of a square profile pipe 20x20 mm.

Pipes must also be clamped with a clamp and cut to the same size.

After all the parts are ready, they can be welded together, as shown in the following photos.

At the next stage, you can attach the angle grinder to the finished structure and check again what came of it.

The ready-made pendulum mechanism for the grinder is easy to install on any flat surface, for example, on the workbench. Also, this design can be installed on a table specially made for it. For a more rigid fastening of the mechanism, small pieces of corners can be welded on both sides of the long corner, and holes drilled in them.

In the following photos you can see how the finished fixture for angle grinders is fixed on the table (in this case, a metal frame is used).

It is very important to set a right angle between the plane of the cutting disc and the plane of the table. Put the square on the table and move it to the abrasive wheel mounted on the angle grinder. If initially you managed to weld the fixture so that the angle between the planes was 90 degrees, then that's good. If you notice a deviation from a right angle in one direction or another, then you can correct the situation with a crowbar or a long profile pipe, for example, 60x20 mm.

To prevent the part from moving when cutting, a corner can be screwed onto the table, which will serve as an emphasis. Also, for an accurate cut, the table can be easily improved with a simple vice made of a nut welded to it and a stud of the required length screwed into it.

Next, you need make a protective cover. It is done taking into account the maximum diameter of the cutting disc, which is permissible to put on a specific model of angle grinder. To make it easier to determine the dimensions of the casing and places for attaching it, you can first make a template, for example, from a piece of cardboard.

In this case, the casing will also serve as a limiter for the cutting tool, which does not allow it to go deep into the table too much during the processing of the part.

It will not be superfluous if for a lever with a grinder attached to it make a spring. In this case, this is easy to do: insert a smaller tube from the back of the rod and attach a spring to it, as shown in the following photo.

On this, the manufacture of a cutting machine with your own hands, in which an angle grinder is used as a drive, can be considered complete.

Option 2

Another version of the fixture for the grinder, with which it will be possible to cut metal blanks, is done as follows.

Thus, a simple cutting machine was obtained. To give additional rigidity to the attachment of the device to the lever, you can use clamps, after laying a wooden block between the angle grinder body and the pipe, for example.

For precise cutting, so that the workpiece does not move, you will need to screw the corner to the table.

For a little grinder a similar version of the device is also suitable, only the angle grinder will be attached to a metal strip: on the one hand, with a bolt to the angle grinder itself, and on the other, with a clamp.

For a powerful angle grinder the fixture is made according to the same principle, but from profiles of a larger size than in the figures above.

It is not necessary to use dumbbells as a counterweight. All you have to do is find the right spring.

Option 3

This fixture option is the simplest for making your own. It is made without a traditional stand (rack) for a rotary unit. 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 canopy, and on the other, for the bolt with which the strip will be attached to the grinder;
screw the angle grinder and the canopy to the strip;
screw the canopy to the table;
fasten 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 high-quality cutting machine. This device is also mobile, because it can be carried with you in a tool case, and, if necessary, mounted on any flat surface.

When installing this fixture, do not forget to fix a corner on the table to rest the workpiece in it.

Cutting sheet hoist with angle grinder

To cut sheet metal, you will need to purchase special carriage, which moves along the guide (profile square pipe).

But as practice shows, the cost of a good carriage is high (more than $ 100), so you can make it yourself. Since this process is quite difficult to describe, you can understand the manufacturing technology of this slider from this video. With the help of the device, you can cut not only steel, but also ceramic tiles and porcelain stoneware.

Please note that when cutting ceramics, a lot of dust is generated. Therefore, it is recommended to adapt a dust collector with a nozzle for a vacuum cleaner to the casing of the angle grinder.
