How to make a grinder from a grinder

Batch crusher for fine grinding

To obtain a finer grind, a different design is used. If in the first case the cutting mechanism is at the bottom, then in this embodiment it is at the top. This design of the crusher is technically less complicated, since the base does not need to be made for manufacturing. The pan is attached directly to the grinder using corners. One hole was made in it for the grinder shaft.

When mounting on a shaft, a felt gasket must be fitted. It is forced onto the motor shaft and prevents dust from entering the mechanism. The entire device is fixed with a clamp to the table. The crusher is ready to work.

The disadvantages of such a grain crusher include low productivity. The advantages are as follows:

  • you can get a fine grind;
  • the structure can be used as a feed cutter;
  • beekeepers can make powdered sugar to make kandy.

Continuous grain crusher

To make a weaving crusher from a grinder, you will need the following tools and materials:

  • drill or screwdriver with a set of drills;
  • jigsaw or saw;
  • open-end wrenches;
  • hammer and chisel.
  • plywood 10 mm thick;
  • corner or staples;
  • bolts and nuts;
  • a saucepan of a suitable diameter;
  • knives;
  • Bulgarian.

Manufacturing begins with attaching an angle grinder to plywood using a bracket or corners. To do this, a rectangular hole is made in it for the angle grinder body and a round one for feeding grain. Fix the bracket with long bolts. The base can be made of various materials:

  • plywood;
  • metal;
  • wooden board.

In the photo, the base is made of 8 mm laminate. The staple can be made of any thin metal that can hold the clipper. M10 bolts were used for fastening. Knives are made of ordinary steel, 3 mm thick.

The sieve can be prepared, for example, an old pan with a drilled bottom or any suitable container. Pictured is a fitted pan with a drilled bottom (holes with a diameter of 5 mm).

Then the angle grinder is fixed and the knives are screwed on. They can be with two or four blades.

It remains to fix the saucepan to the base, and the device from the grinder is ready. The receiving hopper of the grain mixture is installed, which is made of a five-liter bottle. The result is a continuous grain crusher.

The whole structure is installed on a suitable container, connected to the network and the grain is poured into the receiving hopper. The grain mixture is fed into the working area, where the grinding takes place.

The main disadvantage of this design is that the grinding size cannot be adjusted. The grain fraction is uneven. If a gate is installed on the receiving hopper, it will be possible to regulate the grain supply. This is done in order not to overload the car engine.

Grain grinder and shredder of branches from angle grinder

An increasing number of people are moving to cottage settlements and private households. Often the owners organize micro-farms in their backyard, where they raise poultry and animals for their own consumption. The animals must be provided with high-quality feed, but it is impractical to purchase compound feed for a small livestock, therefore the owner is faced with the question of producing his own feed. Buying a grain crusher for several chickens or ducks is not economically viable. Such a mechanism can be made with your own hands from a grinder, which is available in every private house. The result is a small grain crusher capable of providing feed for a small farm.

Utilizer of branches and plant waste

In a subsidiary farm, there is often a need to dispose of branch waste. To do this, they can simply be burned, but this is prohibited, as it can lead to fires. At enterprises, industrial shredders are used for disposal. But for small farmsteads, it makes no sense to purchase expensive shredders. Their work requires large volumes of branches and small trees.

Using the angle grinder, with a slight modification, you can make a homemade shredder. With its help, it is easy to turn various plant waste into dust, and then use them as mulch or as an additive in the preparation of compound feed.

For its manufacture, a sheet of metal with a thickness of 4-5 mm is used, in which two holes are made: one for the grinder’s shaft, the second for supplying waste. Then a small piece of pipe is welded, the grinder and cutting knives are fixed. To ensure safety, the knives are covered with a standard cover. The shredder is ready, it remains to fix it vertically and get to work.

When making a device from an angle grinder, it should be borne in mind that it is not designed for continuous operation. After working for 4-5 minutes, let the electric motor cool down for 15 minutes. It is advisable to use a machine with a power of at least 1500 W.

Following the link, you can see how to make a simple crusher with your own hands.

Grinder for cutting tiles: can it be used instead of a tile cutter?

Renovation work in your own apartment or house often begins with premises such as a kitchen or bathroom, where tiles, porcelain stoneware or decorative artificial stone are required. However, manufacturers cannot agree on the size of the tiles so that they fit perfectly on the wall, often cutting the material is required, which is easiest to do with a special tool called a tile cutter, which is not available to everyone, and its cost is considerable.

In most cases, home craftsmen and craftsmen have gotten used to cutting tiles with a grinder, which is not so easy to do without excess dust, torn edges and chips. In order to properly cut a tile with a grinder, without leaving absolutely any traces on its surface, it is worth studying all the subtleties and nuances of this work.

DIY tile cutter from a grinder

If you need to saw off only a few pieces of tile, then holding the tool in your hands, that is, by weight, is quite appropriate, but when the work is serious and you need to cut a lot of tiles, then this option is hardly suitable. You can use the services of someone from your family or friends who volunteered to act as an assistant, which will greatly facilitate and speed up the process. However, this is not always possible, therefore it makes sense to figure out how to make a tile cutter from a grinder with your own hands, which is quite feasible at home.

Ideally, to make it easier for yourself to work independently, you just need to free your hands with which you have to hold the grinder. When it became completely clear how to cut ceramics with a grinder manually, it remains to figure out how to fix the tool so that you get an improvised tile cutter from a grinder, and it should be functional and convenient.

  • When figuring out how to make a tile cutter from a grinder with your own hands, you should remember that for such a device, which will become a full-fledged machine, you need a reliable, and besides, also a fairly heavy base, best of all made of metal. The table top should have a cut under the grinder’s blade, which you can do yourself, using the same tool. It is this line of the gutter-cut that will serve as a guideline for you when working, so you will have to make it as even as possible.
  • The main difficulty lies in securing the grinder on the bed in a fixed position and in the desired position. For high-quality fixation, use special clamps that you can make yourself, but it is better to purchase such fasteners of an industrial design, so as not to worry that in the midst of work they will rip them off, because this can be a danger for the master.
  • If you add a reservoir of water to the bottom of the groove, and also purchase a special nozzle for wet cutting, you can significantly reduce the amount of dust during work.

After everything is done, and the tool is securely fixed in special clamps, you can figure out how to cut ceramic tiles with a grinder, and the video at the end of the article will clearly show what’s what. Only after trying how everything works on a tile and having cut several tiles, feeding them from oneself, it will be possible to evaluate the better to cut the tiles with a tile cutter or grinder, how much the second option will simplify and speed up the work. True, round holes, as well as oblique cuts, can hardly be made on such a tile cutter, but this is already a cost, and no one will bother you to remove the grinder from the mountings and bring the job to the end, holding it in your hands.

Homemade tile cutter: types

Before making a tile cutter with your own hands, it is worth deciding what kind of tool you want to have as your faithful assistant? There are certain types of tile cutters, each of which has its own characteristics and nuances of operation.

Before you start making a tile cutter, it is worth watching a training video with a master class

Manual rail tile cutter, aka frame. as the name implies, this type of tool is a special frame with guides for the roller, which will cut the tiles. The cutting roller makes an incision on the front side of the tile and after that, using the platform installed on the tile cutter, you can split the canvas exactly along the cut made. As a result, you get an even edge of the tile, which will now correspond to the given dimensions.

Most often, in order to make a tile cutter at home, the master chooses a ready-made tool already developed by any company and its drawings. Recently, people have taken a tile cutter like Karl Dahm as the basis for their home development.

Features of the electric tile cutter

The more advanced and efficient tile cutter is the electric one. Making it yourself is somewhat more difficult, since you will need knowledge of safety standards when working with dangerous cutting tools. This device works by supplying electricity to a motor that starts the cutting blade.

The cutting attachment resembles a grinder disc. Essentially, an electric tile cutter works the same way. The tile is laid on the work surface, and then gradually fed towards the rapidly rotating diamond disc.

To prevent the formation of large amounts of dust, the electric tile cutter must be equipped with a water container. During operation, the disc plunges into it, washing away dirt and simultaneously cooling down, which prolongs the service life of the tool.

The electric tile cutter has the following advantages:

  • allows you to quickly process large volumes of material;
  • cuts even durable porcelain stoneware and stone;
  • makes a smoother cut;
  • less wear and tear compared to manual models.

Although the electric tile cutter can be carried from place to place, it takes up more space. In addition, its cost is higher than mechanical.

To prevent dust build-up, the electric tile cutter is equipped with a water tank

DIY tile cutter: 3 types

To make a tile cutter with your own hands, you do not need to buy expensive materials Repair work around the house requires full dedication, a lot of effort and the use of special equipment that can make life easier for the master. Many apartments and, in particular, bathrooms are rarely standard, and the craftsmen have to come up with time and again how to fit the usual sizes of finishing materials on a non-standard area of ​​the room? For example, it is often necessary to cut linoleum, plasterboard tiles or ceramic tiles for walls or floors. This is encountered not only by the masters of finishing repairs of apartments, but also by the residents themselves who decided to start repairs, for example, if they want to change the tiles in the bathroom or toilet, and also when the question arises about replacing the missing tiles.

How to cut tiles with a grinder

High-quality and simple cutting of tiles with a grinder should be done as professionally as possible, that is, in the end you should get an even, smooth cut and a minimum amount of dust in the process. There are three main directions of the notch, which will not hurt to understand in more detail.

Circular from a tile cutter: the nuances of use

Some people wonder if a tile cutter can be made from a grinder, then can a circular cutter be made from a tile cutter of any brand? There are situations when there is a need for a mini circular, and the standard tools are too large for any miniature work, for example, to saw a thin sheet of fiberboard, or when working with wooden platbands.

When using a homemade circular from a tile cutter, you should strictly follow the safety rules

When you decide to make a miniature circular out of your tile cutter, remember that in this case you need to pay attention to the number and speed of revolutions of the disk plate, which in the tile cutter works like a cutting roller. Turns should be no more than 4000. In addition, for your own safety, take care of the presence of protection, for example, protective covers, which can also be made by yourself.
In addition, during the manufacture of a circular from a ceramic tile cutter, also do not forget that it is necessary to prepare a flat work surface, which must be reliable and comfortable, otherwise, there may be injuries, including quite serious ones.

Grain crusher

The grain crusher is made of a round drum (from a broken or old crusher) with a perforated removable bottom, a plastic vent (from a conventional canister with a cut off bottom) and a grinder. the leading structural element. The shaft of the angle grinder is placed into the drum through the hole in the center of its upper part. In this position, its body is attached to the drum (the method of attachment is individual). A screw-shaped knife is attached to the gearbox shaft from the inside of the drum. It can be made from a circular saw cut-off wheel for wood. The knife is fixed with a fixing nut.

A plastic grain hopper is also installed in the upper part of the drum body. Through it, grain is fed, falling onto a rotating knife. The latter is crushed and poured out through the bottom perforation. 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 manufacture.


A wood lathe from a grinder is one of the most difficult ways to modify the latter. For its manufacture, a large number of materials and various components are used. An example of construction is shown in the photo below.

Homemade miter saw

LBM of any model and size can be modified into a miter saw. A miter (pendulum) circular saw is an electric tool (rarely battery), used only in a stationary form for cutting workpieces from various materials at an acute and right angle. The differences between such a saw and others are in the high accuracy of cutting at a given angle and maintaining the integrity of the cut edge.

You can make an installable structure with your own hands that will allow you to use the grinder as a miter saw. To assemble the simplest modification, you will need to prepare:

  • wooden blanks. a sheet of fiberboard, corresponding to the size of the future working surface, various bars (it is possible from the same fiberboard);
  • wood screws;
  • bolts and nuts;
  • regular piano door hinge.

Tool required to make a miter saw:

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

Build process. The future pendulum frame of the miter saw should be positioned on a firm, level, non-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 miter saw blade is always positioned at the edge of the 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 the smallest angle grinder, a 50×50 cm fiberboard sheet is suitable.It must be fixed on the workbench so that one edge of it protrudes 15 cm above the floor. A rectangular cutout is made in the middle of the protruding part, designed to lower the grinder’s cutting element into it. The width of the cutout varies from 10 to 12 cm, the length is 15 cm.

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

A bar or a rectangular piece of fiberboard is screwed to the moving part of the loop. Another blank of a similar profile is attached to it at an angle of 90 degrees. the part on which the grinder will be fixed. In this connection, you can use a reinforced mounting angle. this will reduce the backlash of the structure and eliminate the occurrence of errors when cutting.

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

The back of the grinder is attracted to the support bar with a plastic clamp. The start button must remain accessible for emergency shutdown of the power tool. A 5×5 cm wooden bar is screwed to the plane of the working area, designed to be used as a stop for cutting a workpiece made of wood or metal. Its presence will ensure smooth cutting and no beating of the material. The design in question upside down and with a fixed grinder can be used as a homemade sawmill. Depending on the intended purpose, it is possible to manufacture a portal frame for a grinder.

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

There are also more complex modifications of the grinder to the miter saw. Factory variations are also available.


This is a tool that is designed using a benzoin trimmer, or rather, a gimbal. The principle of its operation is preserved. only the driving unit and the cutting part itself change.

Instead of a line for cutting grass, a chain saw bar mount is installed.

Wood shredder

The shredder of branches and grass is a garden device that allows you to turn small branches and thick-stemmed weeds into a small-fraction form used for various agricultural purposes. When making such a tool, it is worth using only a large grinder operating at high speeds. To prevent overloads and breakage of angle grinders, an additional gear system is used, which greatly increases the grinding effect. The device is mounted on a sturdy metal frame that can withstand high vibration and displacement loads. Such a device is shown in the photo below.

How to make a grinder from a grinder?

Grinder is a belt sander. This tool is produced by manufacturers in a self-modification Alteration of the grinder will help to get access to the grinder functions without buying an additional tool. There are many modifications of the homemade grinder. The main difference between them is the degree of complexity of the assembly. Below is a description of converting a grinder into a grinder in one of the easiest ways.

You will need the following materials for assembly:

  • 70 cm of metal tape 20×3 mm;
  • three bolts with a thread corresponding to the thread of the mounting holes of the grinder’s gear housing;
  • several washers and nuts of the same size;
  • three bearings;
  • a small pulley with a hole diameter equal to the diameter of the working shaft of the angle grinder.

Assembling the frame structure. The main frame of the grinder has the simplest modification: it consists of a horizontal part made of a prepared metal strip, and a fastening part attached to it, which has the shape of the letter “C”. The fastening part is designed to secure the entire grinder frame to the grinder’s gear housing. To do this, holes are drilled in it, which must match the holes in the gearbox. They are designed to screw in the grinder handle. The oval shape of the holes will make it more convenient to fix the frame on the angle grinder.

The horizontal part of the grinder is welded to the fastening part so that the edge of the former is in the middle of the latter. When cooking, the correct position of the edge of the horizontal element must be observed. It should have the best resistance to lateral loads that occur during the operation of the grinder. Installation of a belt drive. The polishing machine works on the principle of a belt transmission of rotational force. An emery tape acts as a belt. To carry out the transfer, it is necessary to fix the pulley on the grinder shaft using a nut of the appropriate size.

At the end of the grinder frame, which is opposite to the angle grinder shaft, a hole with a diameter of 6 to 10 mm is drilled. A bolt is installed in it. Its direction must match the direction of the gear shaft. Several bearings with an inner hole diameter exceeding the bolt section diameter by a maximum of 1 mm are put on the bolt. this will give the bearings the opportunity to sit tightly and not give vibration during the operation of the future belt sander. The bearings are secured to the bolt with a washer and a nut.

The final stage in the assembly of the hand grinder is the preparation of the emery cloth. A common abrasive belt used in factory versions of grinders is cut longitudinally. The width of the cut must match the width of the pulley and the bearings on the opposite side of the grinder frame. Additional Information. When assembling this grinder model, it is worth considering the correspondence of the length of its frame to the length of the emery belt. The grinder attachment can be of a fixed size for a belt of a certain brand or with the ability to adjust the tension.

To introduce the adjusting properties into the design of the product, it is necessary to pierce the existing holes in the frame. These are the holes used to fasten the structure to the gearbox housing, as well as the one used to hold the bearings. In the process of grooving, the holes should acquire an oval shape. this will allow the frame to be shifted to the side, thereby adjusting the tension of the belt drive. To improve the properties of fixing the tension and prevent it from loosening during the operation of the tool, it is necessary to put ribbed profile washers under all the nuts.

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

Electric saw

An electric saw from a grinder is made using a tire from a chainsaw of the appropriate size. Since it is not possible to use an automatic rotation stop mechanism in a self-made design, special attention is paid to the design of a protective casing. According to a similar principle, a reciprocating saw based on a grinder can be designed with your own hands. The chain saw is shown in the photo below.

Basic tools and materials

Modification of angle grinders does not imply changes in the design of the grinder itself. In most cases, the alteration is the assembly of the hinged frame, which is installed on the grinder. The set of tools and materials used to assemble such a structure is determined by its purpose and the degree of complexity of the design process. The main parts of the grinder’s attachment are a variety of bolts, nuts, clamps and other fasteners. The base is a supporting frame made of durable metal. an iron square pipe, corners, rods and other elements.

Additional tools are used to convert angle grinders into a device for other purposes. Among them are:

  • electric drill or screwdriver;
  • welding machine;
  • spanners;
  • another grinder;
  • vice.
