A simple homemade modification of an angle grinder with your own hands

DIY homemade grinder with a burnt anchor
From the motor and gearbox of an angle grinder you can make excellent tools for working in a home workshop. But what to do if the engine of the angle grinder is completely out of order.

For example, I had one case when, after purchasing an angle grinder, a few days later the armature winding was damaged. I don’t know what they did there, but since then I haven’t bought cheap angle grinders.

In general, while cutting metal, an unpleasant smell of burnt plastic came from the body of the angle grinder. Then sparks and the characteristic sound of the anchor jamming. Having disassembled the angle grinder, I found out that the armature winding was badly damaged; probably, the wire began to cling to the body during operation.

That's it, buy cheap low-quality grinders. They won’t mention the manufacturer of the angle grinder, but I’ll just say that it’s ours, domestic. In general, without thinking twice, I decided where I could use the angle grinder with a burnt out engine. See what happened below.

How to make a start button for a pendulum machine from an angle grinder

The angle grinder works when you press a button. At the same time, the spindle rotation speed depends directly on the pressing force of the button. This means that the button has a built-in adjustment mechanism, the operation of which simplifies the operation of the tool. When operating an angle grinder on a stationary machine, you need to think about the starting system so that you don’t have to hold the handle with one hand and press the button with the other.

If the tool is equipped with an ordinary button, which is automatically locked when it is turned on, as, for example, in the first version of the machine, then no problems arise here. First, the tool is turned on, and then you can do the work. But most angle grinders are equipped with self-switching keys, which must be held down with your hand during operation. There are two ways out of this situation:

• Use ties (for example, plastic) or clamps of appropriate diameter. They fix the button in the pressed position. With all this, you also need to take into account the latch, which is responsible for turning the tool on automatically. Both the latch and the button must be tightened with a clamp, tie, or other similar materials. With all this, the mechanism of operation of the device will be the following - as you need to start the tool, you need to insert the plug into the socket or make a switch
• Reworking the starting system is the right thing to do if the tool is planned to be used more often as a cutting machine than as a stand-alone grinder. To do this, you need to connect the wires from the angle grinder to a separate switch, which will turn the tool on and off if necessary.

The power button, if it is displayed, is best placed on the handle. A homemade machine does not require huge costs for its production, which, in fact, is its main advantage.

Starting device for a homemade machine

Let's look at this component in more detail. There is a good old version of the NVG 30-U start button.

The principle of operation is as follows - to start the device you need to press the “start” button with force. To turn it off, simply lightly touch the “stop” button, which is located above the start key. For emergency shutdown

very convenient and safe.

There are also modern interpretations. The principle of operation is the same - the shutdown button is more accessible than the start button.

The safest way to turn on an angle grinder on a cutting machine is with a non-fixed pedal. Control is performed with the foot, both hands are free at the time of launch. In case of an emergency, simply remove your foot from the pedal - the instrument is de-energized.

Of course, this makes the design more expensive, but safety issues have no monetary value.

Quite a lot of designs have been invented, using different materials - wood, textolite, metal profile. In our opinion, the most successful in terms of safety and accuracy of work is a homemade machine made of profiled steel pipe.

Option 3 - an even easier way to make a cutting machine from an angle grinder

Many people do not have welding machines or cannot use them, so if you belong to the category of these people, then you should not despair. There is also no need to ask your friends and neighbors to make a machine. It is completely possible to do without welding, and bolts and nuts will be used as the main connectors. So, to construct a simple cutting machine from a grinder, the following consumables will be useful:

• Corners - at the same time, their small number is up to 1 meter. If there are pieces, that's even better. Corner thickness is standard 2-3 mm
• An iron tube 30 cm long - will be used as a handle on which the grinder
• Metal sheet 2-3 mm wide and random in size, but more than 20x20 cm
• Bolts with nuts with a diameter of 8-10 mm

Let's start making a homemade instrument. The production process is as follows:

• First, you need to attach a corner 15 cm long to the iron sheet
• Attach another corner perpendicularly to the wall of the lying corner using bolts and nuts. If there is welding, you can make tack welds
• Attach the tube to the perpendicularly installed angle using the same bolted connections
• The tube should move freely, so there is no need to tighten the nut on the bolt. Instead, you need to tighten the fixing bolt with another nut.
• Connect two iron plates measuring 5x6 cm to the tube at a distance from the connection point. These plates will be used to attach the grinder
• Attach the angle grinder to the casing with pre-prepared iron plates

In the end, we get a simple cutting machine, a photo of which can be seen below.

There are many options for producing such structures, so everything depends on what you want to get in the end and what consumables are available. Working with the version of the cutting machine discussed above is not entirely comfortable, as you need to constantly hold the tool (due to the lack of a return mechanism), but this is easy to fix. It is necessary to attach a spring to the protruding part of the tube, which will return the tool to its initial position, eliminating the need for the master to delay the operating unit.

There is only one way out - make a cutting machine with your own hands

What elements must be foreseen in the design:

A strong, not languid frame. The best option is to securely fasten the structure to a stable workbench;

The stand for the rocker will fit strictly perpendicular to the table.

• A swinging bracket (yoke), which is made taking into account the design features of your angle grinder;
• Comfortable grip handle, which ensures safe vertical movement of the angle grinder;

If you can secure the grinder in such a way that you can use the standard handle, this is the most reliable option.

A spring that will return the tool to its initial position after finishing the cut;

The correct option is a tension spring with a return stroke of less than 2-25% of the stroke of the angle grinder gear axis.

Mandatory with the use of any kind of disc, for example an abrasive, as it is also called an iron circular. The open working sector is not expected to be oriented towards the operator.

Option 1 - a simple way to make a cutting machine from an angle grinder

The usual method for producing a homemade product involves making a base on which fixed connectors for the movable plate are attached. So, more carefully about how to do

angle grinder machine:

• An iron plate measuring 15x15 cm and more than 2 mm wide is taken. Such a large size is needed in order to secure it to the workbench with bolted connectors. If the workbench (table) is metal, then the base can be welded to it, so in this case you can use a smaller plate 10x10 cm
• Weld two rectangular plates perpendicularly to the base, located at a distance of 5-8 cm from each other. The thickness of the plates should also be more than 2 mm. Their length depends on the size of the power tool, but usually small or medium-sized grinders are used for stationary machines, so the length of the plates is 8-10 cm
• At the base of the plates, make a straight hole into which the connecting bolt is installed. The diameter of the hole is 6-8 mm, which is not so important
• In the next step, it will be useful to make a movable base to which the grinder
  . To do this, it will be useful to take an iron plate more than 20-30 cm long, which depends on the size of the power tool. The width of this frame should be slightly less than the distance between the protrusions of the rectangular plates welded to the base
• On the reverse side of the movable plate, it is necessary to weld a round oblong sleeve into which the connecting bolt will be placed
• You need to secure the tool to the resulting movable plate using clamps, ties and other methods. The number of fasteners should be more than 2, and preferably more than 3 for greater safety
• Having secured the resulting structure to the workbench, you can test its operation

For ease of operation, you can weld a handle to the movable bar, and also install an auto-return spring, which will return the tool to its initial position, in other words, move it upward. The photo below shows a ready-made installation for cutting from an angle grinder. As can be seen in the example, its production requires a minimum of effort and materials, and the end result is a stationary device for cutting various materials.

When constructing the device, do not forget that safe operation depends on how to secure the angle grinder. It must be firmly fixed at 2-3 points, which will prevent it from moving during work and also from “flying off” from the movable frame. When installing the tool on a movable bed, it is necessary that the position of the grinder be strictly at a right angle, in other words, the circle must be placed strictly in a vertical position.

The purchased device is suitable for processing various materials from wood to hard stone. When working with equipment, do not forget to use safety glasses, gloves, and protective clothing. Instead of a workbench, you can use a wooden or iron frame on which to realize your idea.

Advantages of a cutting machine from an angle grinder

If necessary, simply cut pieces of an old water pipe for gartering cucumbers - accuracy is not a matter of principle. In cases where precise cutting of the material for welding any structure is required, a tolerance of 3-5 mm will be critical.

The next problem is maintaining the perpendicularity of the cut. It is virtually impossible to achieve a straight strip at an angle of 90 degrees to the axis of the workpiece, holding the grinder on your palms. The same goes for fixed angle cuts. When misaligned, abrasive discs are often destroyed, and fragments can cause injury.

When you cut a lot of workpieces, after 2-3 hours of work you will generally not have the strength to hold the tool in your palms, there is no need to talk about accuracy here.

Sawing wooden blanks is a separate topic. Carefully about the grinder blades for wood, not about how you can cut wood with them here. Using special discs, which can be used to safely work on wood, you will not achieve a high-quality cut. And proper circular saws mounted on angle grinders are fatally unsafe for the master holding the tool in his palms.

There are factory versions of machines that fix the grinder without turning the work of cutting blanks into a harmless, unclear task. But such devices are quite expensive, and are not even always universal. Simply put, finding a specimen that is perfectly suitable for your angle grinder is a difficult task.

Option 2 - how to quickly and easily make a pendulum saw

If you have a welding machine and consumables, you can make a stationary machine from an angle grinder in a matter of hours. At the same time, there is no need to take anything for this, because the necessary pipes, fittings and profiles can be found in the garage or a pile of scrap metal. To construct a simple cutting machine using an angle grinder as the main tool, it will be useful to use the following parts:

• Iron profiles size 150-200 mm
• Sleeve 10-15 cm long
• Hairpin 20 cm long and 8-10 mm in diameter
• Washers
• Iron corner
• A sheet of metal 2-3 mm wide, which will act as a base

So, to produce the simplest homemade product, it will be useful to perform the following steps:

• Cut the pin to the required length, then place the sleeve inside (it should move freely along the pin), and tighten the nuts onto the ends of the protruding pin. Tighten two nuts on both sides, because the second ones will act as a lock nut
• The nuts must not be fully screwed in; they must not come into contact with the sleeve
• The resulting structure should be welded to an iron sheet. In all this, it is important to grab the nuts specifically, and the sleeve must remain mobile, in other words, move freely
• The next step is to make fastenings for the grinder. For this, iron profiles and washers will be useful, which will act as fasteners.
• Cut to the required length (everything depends on the tool used, but for a low-power grinder, the profile length is 15-20 cm). Weld washers to the ends of the profiles. It is recommended to use at least 2 mounts for an angle grinder, but three is better
• The angle grinder has threaded holes for connecting a handle. We use these holes to attach the tool to the movable base using previously prepared fasteners
• First, the fasteners are attached to the tool using bolted connections of the appropriate size, and then the reverse ends of the profiles are welded to the sleeve. In the end, we get a finished machine that can be made in almost an hour

The photo below shows the design of a homemade machine made from a grinder with a detailed description of the necessary materials. Using the annotation, and for some, a diagram is enough to make a homemade cutting machine. With all this, it is important to take into account that the angle grinder must have a casing, otherwise the risk of serious injury increases. Operating the tool without protective clothing, not only on a person, but also on the device itself, is strictly prohibited.

The simplest device is ready for use. The angle in the machine design is used as a guide for centering cutting materials. It is also necessary to make a straight hole in the metal sheet, into which part of the disk will “go” when sawing workpieces.

Making a homemade machine from a grinder features

It is not difficult to make a machine from a grinder without the help of others. At the same time, there are many production options, which depend on the available materials and imagination. There are two types of stationary cutting machines made from grinders:

• Ordinary - it received this name for one reason, which is not only the simplicity of production, but also the miniaturism of the device itself. The tool is attached to the workbench using additional materials, and it can be used
• It’s not easy to make such machines correctly if you plan to often use it for various actions. Almost always, a simple device is enough for a home garage, the production of which requires little time, effort and consumables.

In order to make a cutting machine from a grinder with your own hands, you will need consumables, which are iron plates, as well as profiles and fasteners - bolts, nuts and washers. The only special tools that are useful are an electric drill and a welding machine. Let's look at how to make a simple version of a cutting machine from a grinder in more detail below.

Making a wall chaser

What can you make from an old grinder? Home craftsmen ask themselves this question quite often. But if your angle grinder works properly, you can use it to make a wall chaser. By using equipment without modification, you are putting yourself at risk. In order to avoid risk, you can make a nozzle with a solid base, which will allow you to make cuts in the walls over the entire diameter of the disk.

This addition is a footplate in the form of a stop that allows you to move the tool along the wall. The efforts will be uniform. When you make such a device, take the time to install a closed cover, which will be supplemented with a pipe for connecting a vacuum cleaner.

Why make a machine from an angle grinder

A cutting machine is a necessary and suitable thing, not only in the industry, but also in the household. With this useful tool you can create precise cuts on parts and workpieces. This is achieved by securely fixing the cutting disc, into the spindle of which you can install not only abrasive wheels for cutting metal. A stationary machine can be used for cutting tiles, bricks, marble, granite and other similar materials, using special diamond-coated wheels in the design of the tool. If necessary, such a machine can be used for sawing beams, boards and other wood workpieces.

Many people who have repeatedly faced the need to make a clear cut on a workpiece want to find out how to make their own cutting machine from an angle grinder and scrap materials. Holding the grinder in your hands, you can also make a clear cut, but it is more difficult to do this, because you have to hold the tool with only 2 hands. Using a homemade cutting machine you can not only do, but also simplify the following work:

• Cut sheet material, such as galvanized sheet metal, used for chimney insulation and other purposes
• Cutting clay tiles and tiles - keep in mind that the cut can only be made straight
• Cut materials at different angles
• Cut an iron profile, pipe, wood beams, boards, etc.

The manufacture of a machine from an angle grinder requires an appropriate approach. After all, the tool itself is very unsafe, so the slightest miscalculation can lead to the master being seriously injured. The consequences of working with an angle grinder if safety regulations are not observed are clear, so first, before constructing a homemade product, the following must be noted:

• Only with the correct manufacture of a stationary cutting machine can you be confident in its reliability and safety
• If you plan to do it
  , then you need to calculate every step so that there is no failure during use
• Using a machine is somehow safer if you work with the equipment while holding it in your hands. But you need to be aware that an angle grinder is a mobile tool, and making a homemade product is already a violation of safety regulations
• For production, you need to use materials of appropriate reliability, proper power and size of the main power tool

Having understood the need for producing a machine, you can get down to business.

Homemade electric cultivator

Those who are engaged in farming, as a rule, have in their arsenal such equipment as a cultivator. Using this equipment, you can process the soil without turning out large layers of soil or disturbing its fertile layer. The only significant drawback of such a device is its price. Because of this, farmers in our country often use a manual or electric cultivator, which is made with their own hands from an angle grinder.

Important points when constructing a pendulum machine

The type of tool under consideration belongs to the category of unsafe, therefore, when constructing the equipment, the following main points are taken into account:

• The manufacture of the frame is the basis responsible for the reliability of the installation. It is impossible to save money on the manufacture of the frame, therefore only iron materials are used, the thickness of which is more than 2 mm
• Frame - the design of this part can be different, but the most important thing is to ensure the mobility of the cutting tool. This is achieved through the introduction of various materials, but in any case, you need to think carefully about the quality of the hinge joint, because your life depends on it. It is better to spend more material, but make a high-quality and safe cutting machine
• Tool fastening - the angle grinder is fixed specifically to the moving part. At the same time, the fixation must be as reliable and high quality as possible. When working with an angle grinder, “reverse impacts” may occur, which are unsafe because the machine may simply be damaged, and the master who does the manipulation will suffer as a result.
• Anticipating the improvement of the counterweight is a small but important element that allows the tool to return to its initial position when unnecessary. This will eliminate the possibility of damage to parts of the human body
• A protective casing is a must, and it doesn’t matter what design of the machine is invented, but using the device without a protective casing attached is strictly contraindicated
• The presence of a ruler will allow you to increase the accuracy of the work performed, which is important when cutting parts such as tiles, ceramics, and metal
• The starting device is also a kind of device that affects safety. The control button must be located in close proximity to the master performing the work. This will allow you to quickly react at the right moment by turning off the power supply to the instrument.

In addition to the options when the machine has a moving part, there are also methods for producing cutting devices with the tool located at the bottom of the bed or workbench table top. But this option is only suitable for cases when sawing wood is planned. Below is an example of how to make a home sawmill from a grinder quickly and easily. Details on making home sawmills can be found in this article.

What are the advantages and disadvantages of homemade machines made from grinders?

The homemade products under consideration have certain advantages and disadvantages, which also need to be known to anyone who has set out to make a cutting machine from an angle grinder. The advantages include:

• Having a stationary machine in the garage, you can quickly, and most importantly perfectly, cut various materials
• Obtaining a high-quality and even cut, which makes the device perfect
• Cheap - if you have an angle grinder
  , then the cost of manufacturing the machine will be the lowest

Now let’s find out what shortcomings the homemade device in question has:

• Low reliability - even with the most competent approach, the possibility cannot be ruled out that a person may receive various injuries just because of working on such homemade equipment. To protect yourself, you must work in protective clothing.
• The difficulty of transporting the device depends on its size and weight. Only if the machine is called stationary, then it is intended for operation exclusively in one place

If you have already made the type of equipment in question, then understanding the correctness of its operation will not be difficult. Already from the first test of the tool you can feel how effective its work is. Below is a selection of photos showing options for homemade cutting machines from grinders. In addition, such a tool as an angle grinder conceals within itself a lot of fascinating ideas for expanding functionality, but that’s a completely different story.

From metal pipe and corners

The finished design of such a machine will be a long iron pipe, serving both as a frame and as a handle. Closer to one end, a transverse iron strip with 2 holes for fastening the grinder is welded.

The pipe in this design is both a handle and a fastening

On the same side, the pipe is attached to one side of a small piece of angle on a movable shaft, while the angle itself is attached with its other side either to the work table, or simply to the floor in the work room. On the reverse side of the mount, it is imperative to fix a spring, which will allow the entire structure to return to its original position. That's all - the machine is ready, you just need to secure the angle grinder correctly. Naturally, this option is for the most ordinary work with metal, but for complex work where precision is required, the structure should be more stable and thorough.

In the machine, it is very important to predict the measuring parts, thanks to which you can cut workpieces with an accuracy of just 1 mm. In this case, a movable ruler with a limiter welded to the tube is ideal. Having set a clear size with its help and secured with an end screw, you can get to work.

How to make a grinder from an angle grinder?

A grinder is a belt grinder. This tool is produced by manufacturers in independent modifications. Remaking the grinder will help you gain access to the functions of the grinder without purchasing an additional tool. There are a huge number of modifications of a homemade grinder. The main difference between them is the degree of difficulty of assembly. Below is a description of converting an angle grinder into a grinder using one of the most common methods.

The following materials will be useful for assembly:

• 70 cm of iron tape 20x3 mm;
• three bolts with threads corresponding to the threads of the mounting holes in the gear housing of the angle grinder;
• several washers and nuts of the same size;
• three bearings;
• a small pulley with a hole diameter equal to the diameter of the angle grinder’s working shaft.

Assembly of the frame structure. The main frame of the grinder has the simplest modification: it consists of a horizontal part made of prepared iron tape and a fastening part shaped like the letter “C” attached to it. The fastening part is designed to secure the entire frame of the grinder to the gear housing of the grinder. To do this, holes are drilled in it, which must coincide with the holes in the gearbox. They are designed for screwing in the handle of an angle grinder. The rounded shape of the holes makes it easier to attach the frame to the angle grinder.

The horizontal part of the grinder is welded to the fastening part in such a way that the edge of the first is in the center of the latter. When cooking, the correct placement of the edge of the horizontal element must be observed. It must have better resistance to the lateral load that occurs during the use of the grinder. Installation of belt drive. The polishing machine operates on the principle of belt transmission of rotational force. The sanding tape acts as a belt. To implement the transmission, you need to secure the pulley to the angle grinder shaft using a nut of the appropriate size.

At the end of the grinder frame, which is the return shaft of the angle grinder, a hole with a diameter of 6 to 10 mm is drilled. A bolt is installed in it. Its direction must correspond to the direction of the gear shaft. Several bearings are placed on the bolt with a diameter of the internal hole that exceeds the cross-sectional diameter of the bolt by a maximum of 1 mm - this will give the bearings the opportunity to sit tightly and not cause vibration during operation of the future belt sander. The bearings are secured to the bolt with a washer and nut.

The final step in assembling a hand grinder is preparing the sanding cloth. An ordinary abrasive belt, used in industrial modifications of grinding machines, is cut in the longitudinal direction. The width of the cut part should correspond to the width of the pulley and bearings located on the back side of the grinder frame. Additional Information. When assembling this model of grinder, it is worth taking into account the correspondence of the length of its frame to the length of the sanding belt. The grinder attachment can be of a fixed size for the tape of a specific office or with the ability to adjust the tension.

To implement adjustment parameters in the product design, it is necessary to machine the existing holes in the frame. We are talking about the holes used to fasten the structure to the gearbox housing, as well as the one used to hold the bearings. During the grooving process, the holes should acquire a rounded shape - this will allow you to move the frame to the side, thereby adjusting the tension of the belt drive. To improve the tension fixation parameters and prevent its weakening during operation of the tool, you need to slip ribbed profile washers under all the nuts.

A finished variation of the homemade grinder design is shown in the following photo.

Homemade miter saw

An angle grinder of any model and size can be converted into a miter saw. A miter (pendulum) circular saw is an electronic tool (sometimes battery-powered), used exclusively in a stationary form for cutting workpieces from different materials at an acute and right angle. The difference between this saw and others lies in the highest accuracy of cutting at a given angle and maintaining the integrity of the cut edge.

do it yourself

an installed design that allows you to use the grinder as a miter saw. To assemble the simplest modification you will need to prepare:

• wood blanks - a sheet of fiberboard corresponding to the size of the future working surface, various bars (can be made from the same fiberboard);
• wood screws;
• bolts and nuts;
• an ordinary piano-type door hinge.

Tools needed to make a miter saw:

• jigsaw or hacksaw;
• drill or screwdriver;
• two drills – 3 mm and 6-8 mm;
• plastic tightened clamp.

Assembly process. The future pendulum frame of the miter saw should be placed on a rigid, level, not wobbly surface. A workbench table or a separately assembled structure can be used. The height of the plane on which the product will stand must be sufficient for comfortable work. The cutting element of a miter saw is always placed on the edge of a table or workbench. This fact is taken into account when assembling a homemade miter saw.

The size of the working plane of the machine is determined by the size, weight of the grinder and the purpose of its use. For a smaller angle grinder, a 50x50 cm fiberboard sheet is suitable. It needs to be fixed on the workbench in such a way that one of its edges protrudes 15 cm above the floor. A rectangular cutout is made in the middle of the protruding part, designed to lower the cutting element of the grinder into it. The width of the neckline varies from 10 to 12 cm, length – 15 cm.

On one side there will be a machine operator, on the other, a piece of a piano hinge 5-6 cm wide will be fixed. The canopy, like all other wooden parts, is secured using screws. To do this, a 3 mm hole is drilled in the workpiece - this is necessary so that the screw does not destroy the wood material. In the same hole, another hole is drilled - 6 mm in diameter and 2-3 mm in depth - a countersunk hole for the screw head, which should not protrude above the working plane.

READ How to make a screwdriver using a power supply

The angle grinder is attached to the last beam from below. To do this, a hole is drilled in it with a diameter equal to the diameter of the threaded hole in the angle grinder. A bolt of appropriate diameter and length is threaded into it. Any discrepancies between the dimensions of the frame and the angle grinder are compensated for by additional washers, groovers, and gaskets. Its gearbox should be positioned in such a way that the direction of movement of the cutting disc is oriented towards the machine operator.

The back of the angle grinder is attracted to the supporting beam with a plastic clamp. The start button must remain accessible for critical power tool shutdowns. A 5x5 cm piece of wood is screwed to the plane of the working area, designed for use as a stop for cutting a workpiece made of wood or metal. Its presence will ensure smooth sawing and absence of beating of the material. The design in question, upside down and with an angle grinder attached, can be used as a homemade sawmill. Depending on the motivated purpose, the manufacture of a portal frame for an angle grinder may be possible.

The model of the miter saw described above based on the grinder is shown in the following photo.

Homemade wood cross-cutting machine

With the help of a miter saw, a summer resident will significantly simplify his life. A saw of this type is offered in all construction supermarkets, but a branded miter saw is a very expensive pleasure.

In order not to buy such a tool, it can be assembled with a broach using scrap materials and old tools that almost every owner has in his arsenal. Now we will see how you can assemble a homemade miter saw with your own hands. An example of making a cross-cutting machine can be seen here.

Basic tools and materials

Modifying an angle grinder does not imply making changes to the design of the angle grinder itself. Almost always, a remodel involves assembling a hanging frame that is installed on an angle grinder. The set of tools and materials used to assemble such a structure is determined by its purpose and the degree of difficulty of the design process. The main parts of the suspended accessory for an angle grinder are various bolts, nuts, clamps and other fasteners. The base is a supporting frame made of strong metal - square steel pipe, angles, rods and other parts.

To convert an angle grinder into a device for another purpose, additional tools are used. Among them we can highlight:

• electronic drill or screwdriver;
• welding machine;
• spanners;
• another Bulgarian;
• vice.

What can you make from a grinder with your own hands?

Angle grinder – grinder

– works due to a commutator electric motor that transmits rotational mechanical force to the working shaft by means of a gear unit. The main purpose of this power tool is cutting and grinding various materials. With all this, it is permissible to implement it for other purposes due to configuration and refinement of design features. In this way, the functionality of the grinder expands, and it becomes possible to do previously inaccessible types of work.

Grain crusher

A grain thresher is made from a round drum (from a broken or old thresher) with a perforated removable bottom, a plastic muzzle (from an ordinary canister with the bottom cut off) and a grinder - the leading element of the structure. The angle grinder shaft is placed into the drum through a hole in the center of its highest part. In this position, its body is attached to the drum (the attachment method is individual). A screw knife is attached to the gearbox shaft from inside the drum. It can be made from a cutting wheel on a wood circular saw. The knife is secured with a fastening nut.

A plastic hopper for loading grain is also installed in the upper part of the drum body. Grain is fed through it and falls onto a rotating knife. The latter is crushed and poured out through the perforation of the bottom. The size of the grinding fraction depends on the size of the holes in the bottom. The photo below shows a model of a homemade grain crusher and drawings for its production.

Pendulum saw

Do

DIY adaptations for an angle grinder are not difficult. You don't even need drawings here. It is enough to know the principle that is embedded in this or that 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 placed on a movable bushing, and an angle grinder is mounted on it. Any weight coupled with a return spring can serve as a counterweight.

Bulgarian

Perfect for implementation on a stationary machine both as a clearer tool and as a motor with a gearbox for various kinds of homemade products.
Grinders are often used for construction, repair, and installation tasks. The grinder
is profitable because with the number of attachments used, the number of options for its implementation increases.

Circular grinder

You can use a grinder to make a circular saw for working with wood. To do this, you will need to make a reliable frame or base to which the tool will be attached.

If during the manufacture of a cutting machine the cutting tool should be located above the work table, then when designing a milling unit and a circular saw, the opposite is true. The grinder should be placed under the tabletop, from which a certain part of the disk emerges through the corresponding hole. Additionally, you can screw a ruler to the tabletop, which will help you cut wood more accurately.

DIY pendulum cutting machine
