How to make a mini grinder yourself

The need for a miniature tool exists where a person is engaged in the manufacture of souvenirs, models of ships and aircraft, small technical units and parts.
Miniaturization comes in two ways. The first option involves the production of only miniature tools - disks, cutters, etc. The second option involves the production of grinding tools based on miniature electric motors.

First option - Using a drill + (Video)

The first option has a simpler solution. Let's say you need to make a miniature grinding wheel that will be installed in a drill or screwdriver. To do this we can take a broken disk. Using a caliper, we draw a circle of the required dimensions on it. Then we cut out the future miniature disk along the drawn circle. In its center we drill a hole into which we insert a bolt with a diameter of 6 mm. We put the washer on the bottom and tighten it with a nut.

The bolt will be the axis of rotation of the disk. We insert it into the chuck of a drill or screwdriver and clamp it. With this tool you can cut materials in hard-to-reach places or those that are small in size. Finished parts can be sanded.

It is easy to make a miniature cutter for cutting small parts from plastic or wood. To do this, take an ordinary tin stopper from a glass bottle. In the center of it we make a hole for installing the axle. The same bolt with a diameter of 6 mm can serve as an axis. Align the edges of the cork and cut out the teeth. It is advisable to make minimal markings.

Such a cutter, loaded into a drill or screwdriver, can easily cut small wooden planks, for example, for modeling. Plastics also lend themselves to this simple tool.

Second option - Self-assembly + (2 videos)

If the task is to make a miniature instrument with your own hands, then you must initially select an electric drive. A motor from various devices - a printer, an old cassette recorder, or from an ordinary children's electrified toy - can be used as an electric drive.

Depending on the power of the electric motor, you can build a mini grinder in two directions. The first direction is to use a network power source. For example, from an old mobile phone. The second direction provides for a completely autonomous model consisting of a motor that will be powered by batteries or accumulators.

The difference between the two directions is in the design of the case. In the first case, space will only be required for the electric motor, and in the second, a battery compartment will need to be installed.

It is very convenient to use a piece of PVC pipe for the body. If its diameter is slightly larger than the diameter of the electric motor, then electrical tape can be wound onto the motor. You can secure the engine using a glue gun.

As plugs, you can use plugs that are placed on PVC pipes during transportation and storage. It is necessary to make a hole in the front plug for the motor shaft, and in the rear plug for the power wire. The power connector and switch must be secured to the housing.

The ideal option would be to attach some kind of collet clamp to the shaft. This will allow you to use standard burs, drills and non-standard mini cutters and discs. If installing a collet clamp does not work, you can connect the shaft and cutting tool using a double contact from an electrical block.

In a similar way, you can make a case for a mini angle grinder with autonomous power supply. Only after installing the engine in it, it is necessary to install the battery pack. The battery wires will be connected through a switch mounted on the case.

In both cases, on mini grinders you can use both homemade tools and standard industrial ones - burs and drills.

Making a trimmer or lawn mower out of a screwdriver

During work, you will also need a pipe and an angle for it with a diameter of 40 mm.

The remodeling process begins with disassembling the electric screwdriver and removing the motor. Then you need to attach it to the plug. The mounting holes are pre-drilled in it. We secure the electric motor with two screws and solder the leads to the motor. We are installing an electric motor. In this case, you need to insert its wiring into the pipe.

IMPORTANT! Using a marker on the tube, we make a mark in the place where the future switch will be located. Next, you need to attach contact clamps to the ends of the outgoing wires so that you can quickly connect to the battery.

We make a battery holder from the adapter, connect the drive, connect the adapter to the handset. The blades need to be made into knives. Using a regular terminal clamp, we connect the nozzle to the motor shaft. We make a protective casing from a plastic bucket. We glue the part to the pipe. You still need to check how efficient the design is.

IMPORTANT! This device makes it possible to mow only the grass cover that has soft stems.

There are many different options for lawn mowers, which are based on networked models of drills and screwdrivers.

The first step is to create a base from metal, plywood and other materials. Wheels and a control handle will then be attached to it. The electric screwdriver is fixed with clamps or to a stand. Insert the cutting attachment into the chuck. To protect your feet from flying grass, you need to attach a cover to the back of the base.

Feeding is done through a button. But you can do it directly from the network. If you need a fairly functional lawn mower, then take a drill-driver with a power of 0.5 kW or more.

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 many modifications of a homemade grinder. The main difference between them is the degree of complexity of assembly. Below is a description of converting an angle grinder into a grinder in one of the simplest ways.

For assembly you will need the following materials:

• 70 cm of metal 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 working shaft of the angle grinder.

Assembly of 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 shaped like the letter “C” attached to it. The fastening part is designed to secure the entire grinder frame 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 oval shape of the holes will make it more convenient to attach the frame to the angle grinder.

The horizontal part of the grinder is welded to the fastening part so that the edge of the first 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 arise during the operation 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 carry out the transmission, it is necessary to secure the pulley on the angle 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 correspond to the direction of the gear shaft. Several bearings with an internal hole diameter exceeding the cross-sectional diameter of the bolt by a maximum of 1 mm are placed on the bolt - 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 stage of assembling a hand grinder is preparing the sanding cloth. The usual abrasive belt used in factory modifications of grinders 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 opposite side of the grinder frame. Additional Information. When assembling this model of grinder, it is worth considering that the length of its frame matches the length of the sanding belt. The grinder attachment can be of a fixed size for a tape of a certain brand or with the ability to adjust the tension.

To introduce adjustment properties into the product design, you need 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 an oval shape - this will allow you to move the frame to the side, thereby adjusting the tension of the belt drive. To improve the properties of tension fixation and prevent its weakening during operation of the tool, it is necessary to place ribbed profile washers under all nuts.

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

Do-it-yourself mini-drills: assembly methods, required materials and work features, useful tips

Everyone knows that a drill is a very useful and versatile tool on the farm. If you have a drill at home, you can hang a picture on the wall, straighten furniture, and repair a number of necessary items. But what should you do if you don’t have a drill at home, and constantly asking your neighbors is somehow inconvenient?

You can buy it in a store, but this device is very expensive. Or you can assemble a mini-drill with your own hands using scrap materials that are found in almost every home. We will tell you how to do this in this material, presenting to your attention several simple ways to assemble a mini-drill with your own hands at home.

Mini drill made from an electric chuck

The first option for assembling this device with your own hands is based on the use of an electric socket , which can be purchased separately, or taken from a light bulb. If you buy it, it is very inexpensive, but the cost will be justified.

Also, to assemble a mini-drill with your own hands from a chuck, you will need the following things:

• motor;
• a jar of soap bubbles;
• construction knife;
• insulating tape;
• hot glue;
• blowtorch;
• household switch.

Mini drill body and core

Work must begin by preparing the body of the mini-drill, which will serve as a soap bubble jar . This is done like this:

• Prepare a jar lid. To do this, heat up the soldering iron and use it to make a small hole in the lid of the jar.
• The diameter of this hole should be slightly larger than the diameter of the drill base.
• The bottom of the jar must be completely cut out.

Let's start working with the core:

1. We connect the cartridge with the motor. Most often, motors are taken from different tools that have already been used.
2. Before the bonding process, the motor must be completely degreased using acetone.
3. The cartridge can also be degreased, but there is no need to water it like a motor with acetone. Regular wiping will be sufficient.

The fastening method occurs through cold welding . If this method does not suit you, you can also use hot glue. Remember that the more complex your future mini-drill, the more materials you will need to assemble it yourself.

When planting with welding or glue, you need to work extremely carefully so that everything turns out as smooth as possible. It will not be possible to redo the work later, keep this point in mind.

You also need to consider the following:

• at the mounting location on the cartridge there is a hole that needs to be covered before connecting the parts;
• putty is carried out using simple plasticine;
• Only the holes should be filled with plasticine; there should not be any left on top of the cartridge.

Manufacturing process

When you have prepared the body and core, you can begin directly assembling the drill with your own hands:

• Place the cartridge with the motor connected to each other in the jar. This must be done so that the wires that stick out from the socket are then placed in the lid of the jar.
• When the cartridge fits completely into the jar, lock it. To do this, fill the voids on the sides with hot glue and wait until it sets completely.
• Attach the switch to the cover and connect the power wires to it. It can also be placed on glue.
• We connect all the wires to the switch; the connection diagram is standard. You can use an ammeter for accuracy.
• After connecting the wires, they need to be insulated using electrical tape or hot melt adhesive.
• Screw the lid onto the jar and attach the drill to the other side.

The good thing about a ready-made mini-drill is that it can run on both batteries and electric power. We considered the option of assembling a universal model .

Naturally, without having the skills to work with electricity, it will be extremely difficult to assemble such a drill with your own hands. Below we suggest you consider options for assembling simpler drills for small household needs.

How to assemble a drill with your own hands based on the handle body

One of the options for the simplest drill is a homemade device based on a regular ballpoint pen.

To make it you will need the following materials: ballpoint pen ; drill with the required diameter; hot glue; a durable stick with handles at the end that can be used to rotate it.

Pay special attention to the choice of handle for the manufacture of a future drill, and specifically to its body, since during operation the main load will fall on the body.

The requirements for the handle body are:

• it must be as strong as possible to withstand loads;
• the best option is a body made of high-quality metals;
• If there is no pen with a metal body, choose a pen with a thick plastic base.

The build process looks like this:

• Disassemble the handle until only one body remains.
• The lower part of the body, where the writing rod usually sticks out, needs to be unscrewed.
• Instead of this part, insert a drill into the body in such a way that its working part sticks out from under the lower part, and the second part is inserted into the hole that is in the stick.
• The stick is inserted into the body at the same time as the drill.
• To ensure that the structure of the drill is complete, it is fixed to the wall of the housing using hot-melt adhesive.
• When you twist the mechanism using the special handles, the drill will rotate, providing the desired work by pressing the handle body.

Making a drill using a toothbrush

Electric toothbrushes are very convenient to use, but impractical in the sense that the bristles on them cannot be changed and after use, this expensive device, like a simple brush, has to be thrown away.

But you don’t have to do this, using the body of an electric brush to make a drill with your own hands.

We take an old electric brush and cut everything down to the body. Next, you need to connect the motor shaft to the drill using a collet clamp, which must be purchased separately.

When purchasing a collet clamp (or chuck), be sure to find out in advance what the diameter of the motor shaft in the brush is. The motors differ from each other in the diameter of the mounted shaft.

The collet clamp is inexpensive and can be purchased on the radio market or in a specialized online store. It includes a chuck and interchangeable drill bits with different diameters that are inserted into the chuck.

The most difficult thing in this case is to put a collet clamp on the brush motor. The cartridge is designed for a shaft of 2 mm, but the motor here has a smaller one. To do this, each screw for fastening must first be sharpened until it is given a cone-shaped shape so that the minimum diameter of the cartridge mount can be adjusted to the diameter of the motor shaft.

Of course, you can assemble a mini-drill with your own hands not only using brushes or old handles , but also other devices; folk craftsmen come up with new ways to assemble them every day. However, the options discussed above are suitable even for those who have never encountered anything like this and are assembling such devices for the first time in their lives.

Making your own devices

To make working on an angle grinder easier, all sorts of designs have been invented that increase its functions. The presence of equipment makes it possible to use angle grinders as a belt grinding machine. It is not difficult to make accessories for an angle grinder with your own hands, and it will also cost much less.

Accessories for grinders

• Tripod
• Retainer
• Fraser
• Miter box
• Wall chaser
• Extension

A tripod is a device that frees one hand. The angle grinder is held with only one hand, and with the other hand it is possible to support the metal and turn it if necessary. In addition, it makes it easy to set the desired cutting angle. It allows you to do work efficiently and safely. The frame is made of metal profiles, a shock absorber, and sometimes even plywood is used. Such an improvement is only permissible for a machine with 125 mm discs; with a larger size it is dangerous, since you have to remove the casing. You can take different options as a basis or make your own drawing. The main thing is that the tool is securely fastened. The most convenient way is when the angle grinder is attached to the protection casing. You only need 2 10mm bolts and 2 nuts, which are attached to the outer part of the casing. There are 2 more plates and a pipe onto which everything is screwed. And the switch should be made not fixed, you can use a foot pedal, then in an unusual situation it is easy to stop the machine. If the design for cutting metal is strong, then you can use it for sawing wood.

Clamp – there are many clamps, but the best option for fastening an angle grinder is a vice. They hold firmly and there is no need to support with your hand, thereby reducing the risk of injury. Rotary vice increases the capabilities of the machine (oblique cut). When you install the desired disk or file in a vice, you get a sharpening machine, but after unscrewing it, you can do the work manually. And by attaching stops with a slot across the disk, very precise processing can be achieved. The most popular option is a band sawmill made from an angle grinder. You just need to have a reliable frame and strengthen the machine well.

A milling cutter is another device for an angle grinder. The machine has a powerful engine, so it can be converted into a milling cutter. To do this, you should take the shaft into the opening of the workbench and put a chuck with heads for milling on top. The resulting homemade device for an angle grinder is used to process hard wood.

It is important to remember that the device is not designed for this type of work, so you need to take care of your safety.

A miter box is a rotating surface for a grinding machine. Using this device, it is easy to cut plinths, baguettes, profiles at the desired angle

You just need to install the desired disk, then the surface is fixed at an angle of 45 degrees, and the machine is ready for work. You can cut any platband for a wooden house or paving slabs.

A wall chaser is a necessary device for an angle grinder. Used for laying wiring by hollowing out recesses in the wall. However, this is not safe. When making an attachment for an angle grinder that works on a dense base, it can be used to cut walls along the entire diameter of the disk. With a good sole for an angle grinder, its guiding movement is carried out smoothly, without much effort.

Extension cord – used for plumbing and plumbing work in hard-to-reach places.

Profitable conversion of an angle grinder

Cool ideas for profitable conversion of an angle grinder. These interesting DIY projects will help you get the most out of your angle grinder. Do you think we should pick it up and saw something off? Let's not think like everyone else and do homemade products to the fullest.

Previously, the repairman school channel already talked about machines made from angle grinders. Each DIYer does it differently. Here's one option for you. This machine is perfect for sawing molded products. The advantage of this homemade product is that it has its own extension cord. This makes it more mobile. The design itself is very simple. The main table is being made. Recoil spring guns. Platform for attaching an angle grinder. Clamp. Socket.

Browse products for inventors. Link to the store.

Here is a homemade product that many will need. This is a circular grinder. Everyone tries to simply use a grinder with a saw blade on wood without any devices or protection. And this is very dangerous! This device is a casing for an angle grinder with a slide. There is also a handle for convenient use. You can adjust the cutting depth. This casing is small and comfortable. You can always take it with you to various jobs.

The following frame is easy to install. All you need is a piece of angle 50 x 50, a profile pipe 20 x 20, two bearings, the inner diameter of which allows you to install a profile pipe. Sheet metal clamps for side spark arrester. The originality of the spark arrestor is that it is folding. This makes it easy to change the disc. Agree, it’s very convenient. For cutting at 45 degrees, you can use this removable guide.

Universal machine. You can cut molded products on it. Milling steel products. Sharpen drills. Clean and polish metal. Use as a cutting machine for sheet metal. For cutting at different angles and inclinations, fixation in any position allows this.

The following homemade product does not stand up to criticism because working on it is very dangerous. Grinder chain saw. It's easy to do. A chain sprocket is put on the shaft. This saw cuts, but we really don’t recommend using it. It does not contain the most important thing that is necessary for safety! This is a clutch system that may save your life if the chain gets stuck. However, we are not talking about chain lubrication and everything else. I decided to show it only as an example of the desperate thinking of our DIYers.

Here's a stand for this tool, which will make work more enjoyable.

Features of using an angle grinder

metal cutting

If you also use attachments with this tool, you can expand the number of options for its use. In particular, using this tool with attachments, you can perform high-quality grinding of the base of workpieces. They will be cleared of foreign inclusions. Attachments for grinders can be purchased at the store. But if you do not want to pay money, then you can make them yourself.

In some cases, this tool is used as a wall chaser. With its help, grooves are created for laying pipes and electrical wires. To use an angle grinder in this capacity, you will have to perform some manipulations and increase the standard width of the protective casing. In addition, you will need to make a support plate.

This tool can be used with one disk or several at once. If the grinder is used with two disks, then it is necessary to make some changes to the attachment point of this tool. After this, the grinder can be used in standard mode.

It often happens that during repair work there is a need to clean the base of parts that are difficult to access. In such cases, craftsmen most often resort to using a homemade device for an angle grinder in the form of a special attachment, thanks to which a small disk can be carried beyond the dimensions of the angle grinder.

In this case, the rotation will be transmitted using a special belt drive from the main drive. Using this design, materials cannot be cut. However, scale can be removed from the surface of materials without any problems. It often occurs on the surface of welds.

Currently, the market offers a large number of attachments for tools such as an angle grinder. Their use allows you to significantly expand the options for using this tool. If we talk about the most commonly used attachments for grinders, we can highlight the following:

• a device for sanding the base and removing the paint layer from the surfaces of materials;
• beds;
• protractors.

Materials and tools to make attachments for an angle grinder

The cost of the devices is not very high, so everyone can afford them. There are also no difficulties in finding these attachments. However, despite all this, many people still decide to make attachments for an angle grinder with their own hands.

If you decide to make attachments for this tool yourself, then before you begin, you need to prepare the following tools:

1. An electric drill, it is advisable to purchase a set of drills in addition to it;
2. It is advisable to choose discs with a diameter of 125 mm.
3. Wooden bars.
4. Metal corner.
5. Duralumin steel plate.
6. Self-tapping screws.

Assembling a homemade grinder and checking

You need to start making an angle grinder with your own hands by preparing a piece of sewer pipe.

Take a 50 cm pipe and cut a 35 cm long piece from it. Next, prepare the plugs. The large plug needs to be cut a little less than half; it will be used as protection on the angle grinder.

A corner should be screwed to the plug that is smaller in size, 50 mm.

On one side, the corner is screwed to the plug, and the electric motor is fixed to the second half. The entire structure is assembled with bolts; it is not recommended to use self-tapping screws for these purposes.

Then, on the other side of the pipe, a second 50 mm plug is installed. In its center you need to make a hole for the button. Before attaching the plug to the glue, you will need to solder wires to the button and pull them through the pipe to the electric motor of the angle grinder.

The second option is complete assembly with your own hands

Based on how much power you need for a mini grinder, its production can proceed in two directions. In the first option, a network power source will be used, and in the second case, the device will become completely autonomous through the use of batteries or a small accumulator.

Such devices will have different appearance. A stand-alone device will require an additional battery compartment.

It’s easy to use a PVC pipe as the body of a mini grinder. If the diameter of the pipe is larger than the engine, you can wrap electrical tape around it and attach it to the body using a glue gun.

As plugs, you can use ordinary plugs that fit on the same PVC pipe. A through hole is made in the front plug for the shaft, and in the rear plug for the wire. On the case you need to install a power connection connector - a switch button.

If you can attach a collet clamp to the shaft, then such a homemade product will be an ideal solution. The reception will ensure the use of standard burs and non-standard cutters and discs. If installing a collet clamp is not possible, you can connect the cutting tool and the shaft using a double contact from an electrical block.

In the same way, a body is made for a homemade miniature angle grinder that operates in autonomous mode. In this case, when installing the battery, you cannot forget about the battery pack equipment. The wires from this unit are connected using a switch that will be installed on the body of the unit.

In both cases, on mini grinders assembled with your own hands, you can use homemade tools or standard, industrial drills and burs.

A grinder made from a drill is easier to make than the other way around. The grinder or angle grinder (angle grinder) has become an indispensable electric tool due to the wide range of work that can be performed with its help, but it has its drawbacks that interfere with work. With its help, it is not always possible to get to hard-to-reach places and often it has high unregulated speeds, by the way, because of this, increased safety measures are required. But, despite all this, in certain cases it is irreplaceable. We can take advantage of all the advantages of an angle grinder, and also bypass its disadvantages. To do this, it will be enough for us to get hold of a drive shaft with flanges from an angle grinder (I took it from an old, damaged one).

Grinder from a drill in photo explanations

1 Drive shaft 2 Inner flange 3 Outer flange 4 Outer flange wrench 5 Metal cutting disc

We collect in the following sequence

We put the inner flange on the shaft so that it fits into the grooves, then tighten the outer flange.

Only the outer flange is tightened with a special wrench; the shaft is held in place by an open-end wrench on the reverse side of the inner flange.

For work, install a cutting (or other) disc

After installation, we tighten it and install it in the drill chuck; we also tighten the shaft in the chuck well.

Ready! Since the drill has a reverse, the working rotation must go clockwise, as when drilling. The arrows (in the photo) indicate the mandatory direction of movement of the disk; in this case, the outer flange with an internal (regular right-hand) thread will tighten itself and will not unscrew during operation.

You ask: “Where can I get a shaft from an angle grinder if I don’t have an old, faulty one?”

1. In a power tool repair shop
2. Order a turner
3. Build your own version from scrap materials
4. Perhaps there is a rem. kits (not interested)

I’ll share that I worked with this device this season and got a lot of pleasure from the maneuverability and the ability to adjust the speed of rotation of the disc if necessary. I think that, given the opportunity, you will evaluate everything yourself.

Good luck with your renovation!

—————————————— I’ll say right away that the idea of ​​​​using a drill instead of an angle grinder is not mine, I just saw it for the first time at the master “body maker” Alexander Borchaninov.

Assembling a camping electric generator or wind generator

To make a dynamo, there is no need to radically modify the product. After all, everything you need to make a camping generator is already included in the design of the device. Only minor modifications will be needed.

With do-it-yourself equipment, you can charge 6 or 12 V batteries. An electric tool with an operating voltage of 18 V or higher will be suitable for reworking.

The modification is done like this. First, disassemble the electric screwdriver. Then the electronic board is soldered. Instead of batteries, you need to install a diode bridge suitable in size and technical characteristics inside the battery case. Also make a handle with a handle that is comfortable for you. The end without a handle must be secured in the chuck.

IMPORTANT! A diode bridge is needed to ensure that the handle of the electric generator rotates in any direction. To get a simple wind generator, you can insert an attachment with blades instead of a handle.

We remove the cartridge with the gearbox, that is, the rotor part. We insert the electric motor shaft into the chuck. We attach a round metal plate, approximately 1 mm thick, to the gearbox gear with bolts. It will become the basis for fixing the blades, which can be made, say, from plastic pipes. Then we put the clamp with a clamp on the shaft, which is located between the cartridge and the gear.

We cut out the base in the shape of a rectangle from plywood. You can also use thin metal for this. Using a clamp and clamp, we attach the motor with the cartridge to it. To do this, you need to drill holes for fastening in the right places in advance.

In order to protect the wind generator, for example, from dust and precipitation, make a casing from an ordinary coffee can. We insert the base with the motor and cartridge inside. We take glue and secure the elements. To secure the cover you need a sealant.

We attach the made blades to the round plate of the unit. We make a weather vane, on one end of which we mount the assembled generator. We connect the wires to the motor outputs. And now all that remains is to check the output voltage. This is done using a multimeter while the blades are rotating.

IMPORTANT! There are many options for wind turbines. Even the entire screwdriver, equipped with an attachment with blades, is attached to the support.

Option #1

The general view of the machine (although it is more of a device) is shown in the figure:

Its components are an angle grinder () and a pipe, which simultaneously performs the function of a frame and a working handle. It is not difficult to attach the grinder to it using a metal plate made of a thick piece of iron - it will take no more than half an hour. The support for the structure can be made from the same metal sample by welding a corner to it. The end of the lever is mounted on an axis, and its return motion is ensured by a spring.

This model is convenient because it is light in weight and can be installed almost anywhere. And assembly will not require any costs - everything you need can be found without difficulty.

Advantages and disadvantages

Making a stand for an angle grinder with your own hands provides a number of advantages. These include:

• the ability to create a product with the required dimensions;
• the person himself chooses the functionality of the machine being created;
• such a product has sufficient strength;
• the possibility of skew of the cutting wheel and its deformation is eliminated;
• the design is easy to use and fully complies with the desired performance characteristics;
• all work is carried out at minimal financial costs;
• You can remove the grinder at any time and restore its mobility.

This product allows you to perform the necessary functions with extreme precision. Fully meets safety requirements.

Its disadvantages include the lack of control over the work performed and its compliance with quality. Therefore, all actions must be performed diligently and strictly adhere to calculations and drawings.

Safety

When working with an angle grinder, stationary or manual, you should always remember safety

In the case of a stationary option, you need to take into account the direction of the tool and the position of the protective casing - it is important that the casing completely hides the area in which the operator is located. If you have a machine, you will probably have a desire to use the tool for purposes other than its intended purpose - for example, attach a saw blade for wood to an angle grinder, which is absolutely forbidden to do! But, besides this, unlike abrasive and grinding discs, saw blades have sharp teeth, which pose a high danger

Risking your health for a quick cut is simply unreasonable. After installing the tool and the new disk, the operation of the grinder should be checked for at least 1 minute at idle speed - the circle should rotate completely freely, without excessive vibration, without touching the casing

But, in addition, unlike abrasive and grinding discs, saw blades have sharp teeth that pose a high danger. Risking your health for a quick cut is simply unreasonable. After installing the tool and the new disk, the operation of the grinder should be checked for at least 1 minute at idle speed - the circle should rotate completely freely, without excessive vibration, without touching the casing.

Ideas for homemade equipment using a screwdriver

What are the functionality of this or that model? They are determined by the amount of power, torque, and whether there is a shock function.

An interesting nuance is that with your own hands at home you can make a variety of equipment and tools from a screwdriver , which will then be suitable for use in everyday life. If you have set yourself such a task, then prepare not only a power tool, but also additional materials and parts. Without them, you will not be able to remake the screwdriver.

There is a reason for such work. In the sense that each homemade device will cost you less than its factory-made counterparts. And then your manual labor will be more effective. Automation will take over the entire load.

How to Rewind a Grinder to 12 Volts

Do-it-yourself grinder from a drill and chainsaw

Quite often in everyday life you need to repurpose working tools. This does not apply to the situation when you need to use an angle grinder, but you don’t have one. There are options to come to the rescue: a drill, a gas-powered one, or an electric saw, what is the duration of the project, what tools are available.

The usual ineffective method of getting an angle grinder from an electric saw

Grinder from a drill ()

For such a transformation, the following tools will be useful at home:

Before starting the transformation, you need to make sure that in the coming days the drill itself will not be useful in the work. In the last article, I told you how to connect and start a 380-volt motor in a single-phase 220-volt power supply. And later it’s enough to follow the step-by-step instructions:

1. Choose an attachment for your future grinder.
2. Take a small diameter steel rod without grinding off one of its edges. This action is necessary for the best fit into the nozzle. Also, for the best adhesion, you should slightly grind down the places that will come into contact with the petals of the cartridge, not the rod itself.
3. Fix all parts.

A frisky, unusual method for creating an angle grinder

There is no second, more difficult method to achieve the desired result.

1. The chuck is removed from the drill. For an angle grinder it is not necessary, so there is an option to clean it, lubricate it, or store it.
2. Choose an attachment for the upcoming tool. It would be better if it were a part made of strong steel; a lightweight version would be inappropriate here.
3. Choosing a rod. It needs to be of such length that its part protrudes outside the drill by 1.8-1.9 cm. Next, one of its ends should be ground off with a rasp so that in the process a rod comes out that completely coincides with the socket in the nozzle itself. Before the joint, it is worth smearing its ends with machine oil for the best passage.
4. Installation of the ball bearing is carried out to the output area. A rod will be threaded through it for future fixation at the base. If this step is not necessary, the rod is fixed in its own place.

Do-it-yourself 12-volt cordless grinder

Following the instructions, the grinder comes out in 1-2 hours

There is an option to make an angle grinder using this method within a few hours, but you can’t get the necessary tool here.

Grinder made from chainsaw and electric saw ()

A more common method of making a grinder with your own hands is to convert it from a gas-powered or otherwise electric saw. Because of the ready-made fixture

Working of a disc for an angle grinder

will have a number of advantages:

• Possibility of autonomous operation.
• Highest power.
• Cost of operation.

To transform your chainsaw into a different electronic form into an angle grinder, buy special attachments at any hardware store. They will help to accomplish these transformations in a matter of actions.

For an angle grinder, you need to reduce the risk of disc failure. For these purposes, the saw is equipped with a special protective casing. It is also worth reducing the number of revolutions using a speed reducer.

Bulgarian 12 volt ()

For the client to be able to use an electronic instrument, its 12-volt power needs to be converted to 220.

You will learn how to correctly connect single-phase 220 volt electric motors using the example of motors from a washing machine.

Thus, it is natural to power it from a car in which a constant current flows with a voltage of 12 Volts, by installing a special invector.

Low-power invectors should be connected to the cigarette lighter; there are no special requirements. The only aspects are:

• Use at temperatures ranging from 15 to 50 0 C and average humidity.
• Do not allow devices to operate in direct sunlight.
• Do not use the space under the seats for storage, as the invector will heat up during operation. To cool it, you need unobstructed air flow.

It is recommended to connect a more powerful invector to the battery terminals. However, it is prohibited to turn on the ignition or engine if the invector produced is connected to a non-removable battery.

It’s natural to make an angle grinder from different tools that everyone has nearby. Thanks to the instructions, the work can be done with your own hands in just 2-3 hours.

DIY mini drill

To carry out drilling work on miniature workpieces, engraving machines, the so-called “dremels,” are usually used. The name comes from the name of the most popular manufacturer. This is a convenient hand tool, but its cost is usually high (especially for high-quality branded products).

The most common area of ​​application is amateur modeling and production of printed circuit boards. As a rule, an industrial design is redundant for such work: some of its capabilities are not in demand. Therefore, home craftsmen often create instruments with their own hands.

What materials are needed to create a mini drill with your own hands?

• Of course, an electric motor . The power supply is preferably no more than 12 volts: at least for safety reasons.
• Power supply , if possible with a voltage regulator (to change the number of shaft revolutions).
• Housing (in the most primitive designs you can do without it).
• And the second most important part (after the motor) is the drill chuck .

Everything except the electric motor can be made independently.

Although, the cost of the remaining components is so meager that you can limit yourself to only assembling power tools from ready-made components.

Let's look at a few tried and tested options.

Complete analogue of the factory “Dremel”

To make it, you will need a motor with a 5V or 12V power supply, which can be removed from a broken children's toy, a miniature fan, a printer, a tape recorder, or simply bought on Aliexpress.

If you plan to use the drill for more than just drilling printed circuit boards, you can make a convenient housing from a polypropylene water pipe. We select the diameter so that the motor holds tightly to the walls. Ventilation usually runs along the shaft.

You can use an empty tube of construction sealant.

End caps can be cut from any material: for example, PVC or acrylic. If the engine is powerful enough, a charger from an old mobile phone will not work. You need a current reserve of at least 3A (for 5 volts). A good option is an old computer power supply (you can buy it for pennies on the radio market).

Tip: From a computer power supply you can make a universal power supply for your home workshop. Stable power supply 5V with a load of up to 20 amperes, and 12V with a load of up to 8 amperes. You can connect both a Dremel and a soldering iron.

The collet chuck can be purchased in the store: the department of components for engravers and Dremels. If there is a need to adjust the speed, you can make the circuit yourself, or purchase a ready-made unit.

The illustration shows a Chinese regulator and a power supply from an Internet router (12V, 1.2A).

With this homemade “Dremel” you can not only drill miniature holes. By installing the appropriate attachment, you can work with a milling cutter, cutter, or cutting disc.

Drill made from a toothbrush

At first glance, it sounds absurd. But we will talk about an electric brush, which has a completely reliable motor inside. It is enough to get to the steel shaft on which the gearbox with rotating bristles is placed, and the workpiece is in your hands.

The same collet chuck is put on the shaft, and batteries are installed instead of batteries. Or you can adapt a suitable mains power supply.

Drilling walls with such a device will not work, but holes in a printed circuit board will be easy. In principle, you can use any compact electrical appliance that has a conveniently located motor shaft. For example, an old electric razor.

Making a mini grinder

The most important part is to place the bearing on a slightly processed (using a drill and file) mat stand. computer board and press in the cable.

We disassemble the alligator clip and use a homemade clamp to attach the bearing to it. We secure a piece of the speedometer cable with plastic clamps.

We place the electric motor itself, together with the relay, in a can of sealant cut to size (we fill the voids with pieces of rubber). Additionally, we secure it with a bolt that rests against the motor housing to prevent it from turning.

The cutting disc is also homemade. We make a protective casing for it from plastic.

The electrical circuit is simple: pressing the mini-button turns on the relay, which in turn closes the power contacts and supplies voltage to the electric motor.

After assembly, we get a new design with an unusual motor location. When working, we hold the tool in the same way as a regular grinder, only now it has become more mobile.

Ideas for homemade equipment using a screwdriver

The entire range of screwdrivers is divided into corded and cordless models. Both types of products operate using electrical energy, which drives an electric motor. Only the electric motor itself in network devices is designed for an alternating voltage of 220 V, while in battery-powered equipment it is designed for a constant voltage of different values, for example, 12 V, 14.4 V. These design features, together with the technical characteristics, largely determine what homemade products can be assembled a screwdriver .

Electricity is one of the main types of energy used by humanity. Household appliances, industrial equipment, machine tools, and power tools operate using electricity. The work is performed by electric motors of different designs and power, which are powered by alternating or direct current. For this reason, the following technical devices can be assembled on the basis of a screwdriver or from its individual parts:

• garden grass and branches shredder;
• trimmer (electric scythe);
• camping manual generator;
• engraver (mini-drill, dremel, drill);
• wind generator;
• lawnmower;
• grinder;
• mini-machines: drilling, grinding, surface planer, lathe, sawing, sharpening;
• tool for tying reinforcement;
• gate opener drive;
• means of transportation for children: ATV, bicycle, scooter;
• a small ice auger, a hole drill, a construction or kitchen mixer.

The powerful impact model can also be converted into a concrete compactor using a special attachment.

The implementation of each option takes different times and requires additional (insignificant) costs, or is done without them at all.

How to make a frame for an angle grinder

It is obvious to everyone that it is extremely difficult to hold a heavy instrument for several hours. Therefore, to facilitate their work when performing an operation, many craftsmen make special devices called beds. When an angle grinder is equipped with such a device, cutting work can be done using only one hand.

To make a frame, you first need to make a wooden box. You can get by with only one side on which the tool will be attached. All other walls can be removed, and legs of a special design can be attached instead.

But in order to achieve the effectiveness of using an angle grinder with such a device, it is necessary to make some changes to its design.

The first step is to dismantle the casing of the angle grinder. After this, you need to put a disk on the instrument. When this action is completed, it must be pressed against the side wall of the device.

It is necessary to mark where the gap was made for the movement of the nozzle or disk. Its width should not be too large, otherwise foreign objects may get inside the structure during work.

If desired, the gap can be increased. The need for this arises in cases where it is necessary to replace the nozzles without completely disassembling the entire structure. Samples of wooden blocks can be used as support elements. After this, you can begin cutting workpieces.

Support structure and minor modifications

• steel strip or rod;
• welding machine;
• clamps;
• pliers.

Almost always, such an angle grinder is made as a stationary tool, so the working surface must be prepared. Any wooden or metal tabletop is suitable for it, and metal has an undeniable advantage.

The working platform is bent from a 12 mm ribless reinforcing rod or a steel strip (2-3 mm). Externally, it should completely follow the contours of the model used, because during immersion, maximum fixation should be ensured. Typically, 4 transverse stripes are used to form a contour and 3 perpendicular to them for rigidity. The joint is made using electric arc welding.

After such a bowl is installed on the table, it must be tightly screwed to the surface using bolts and nuts (bolts only with flat heads). The fixation must be quite rigid, therefore there are at least 4 mounting points.

At the very end, the tool turns over and falls into place (handle up). The final fixation is carried out using clamps, with which everything is pulled together on both sides.

If you have to work with the tool for a long time, then make a protective casing. To do this, you just need to cut a piece of sheet steel and bend its edges so that it occupies the entire space above the working area. To fix it to the tool, you need to make a clamp from a steel strip (exactly the size of the drill) and fix it with your own hands.

How to make a cutting machine step by step with drawings: 4 reasons in favor of implementing the project

In order not to doubt the correctness of the decision made, study the following facts:

1. without reliable fastening, the workpieces vibrate, increasing the risk of damage to the disk;
2. it is difficult to manipulate a heavy tool with high precision while maintaining the perpendicularity of the cut;
3. difficulties increase when processing thick products, when creating a large batch of similar parts;
4. Using both hands significantly increases the likelihood of injury.

A high-quality machine is necessary to solve the noted problems and improve productivity. It is created according to the following algorithm:

• clarify the purpose and scope of work;
• study drawings of factory analogues and homemade products, choose the appropriate option;
• compose a set of design documentation with a list of necessary purchases;
• carry out assembly according to the approved plan with performance testing.

Top 6 drawings with explanations for making a homemade metal edger

It is not difficult to create a standard circular saw if you attach a grinder under a work table with a slot. It is necessary to consider a guide system for high precision movement of workpieces.

Picture No. 1. Schematic diagram

Look at picture No. 1 to see what a typical edger looks like. Here the angle grinder is mounted on a movable hinge, which somewhat complicates the design. This scheme has several advantages:

• simple and reliable fastening of the workpiece;
• the significant weight of the upper part will help to use less effort when cutting workpieces;
• if necessary, hand-held electric tools are dismantled to perform work operations as usual.

Picture No. 2. Stand for an angle grinder

Such a load frame is assembled from standard steel angles and pipes with a square cross-section. Welded joints are more durable. But it is also possible to create a prefabricated structure using screws and nuts.

Picture No. 3. Assembly drawing of a pendulum saw

This project can be used as an example for making a high-quality metal edger. Equipping with wheels makes it easier to move a heavy product.

For your information! In other racks it is necessary to install screw supports. With their help, unevenness in the floor covering is compensated.

Picture No. 4. Pendulum circular saw

Look at the picture for an example of a wood processing machine. This technique is suitable for cutting large workpieces.

It is necessary to choose a grinder with sufficient power so that it is enough to work with large-diameter discs. A load is secured on the reverse arm of the lever (instead of an electric motor, as in the drawing).

The weight and mounting location are selected in accordance with personal requirements and the characteristics of a particular design.

Picture No. 5. Drawing of a circular saw

This machine can be converted to be mounted at the bottom of an angle grinder. If longitudinal sawing of wood is planned, such an engineering solution will be optimal.

Picture No. 6. Design of a factory miter saw for wood

Look at Picture No. 6. You can use it to make a set of drawings with your own hands. It is recommended to pay attention to the spring, which lifts the working unit to its original state. A rotary table with measuring devices will help create a machine with increased tolerance requirements.

Picture No. 7. Drawing of the frame

In the manufacture of this part of the machine, thick metal is used. This solution increases cost and weight, but extends service life, increases reliability, improves fastening of hinged elements and processing accuracy.

Converting an angle grinder into a machine step by step: 10 assembly stages, electrical diagram for drawings

To create a machine yourself, you need to choose a design that matches your existing skills and capabilities. The easiest way is to assemble a machine from blanks created according to drawings in a specialized metalworking workshop. Otherwise, you will have to master welding technologies and purchase the necessary equipment.

What is the Smallest Bulgarian

It’s hard to imagine modern construction without an angle grinder or, as it is also called, an angle grinder. This equipment is used for a lot of different work, from grinding, cutting various materials to sharpening tools. There are several varieties: professional, mini-grinder, battery-powered and others.

Most of the finishing and roofing work involves processing iron profiles. If for small volumes many still somehow make do with metal scissors, then on an industrial scale there is no way without an angle grinder. An angle grinder (angle grinder) has a wide range of applications both in industry and in everyday life, and a micro- grinder

It is even used in medicine.

Conventionally, the devices are, of course, divided into professional and household, large and small. When choosing a tool, you need to know what it will be used for. Household grinders have the least power and more ordinary functions. You need to give her rest more often, but such a tool will attract you with its low price.

Prof, on the contrary, can work continuously for a long time, equipped with additional devices and functions. They are made from higher quality materials, and the cost for them will be correspondingly higher. Huge and small grinders differ from each other in power, size, weight and work criteria in which they should be used.

The smallest grinder, just like the largest, is characterized by the following basic indicators: motor power, spindle speed, ergonomics, weight and size. Power is an important feature of this tool. It is recommended to purchase a powerful tool.

It will allow you to use cutting wheels with a larger diameter, in other words, it will be able to cut to great depths, and it will also not quickly heat up. The presence of a spindle speed regulator will make working with an angle grinder safer, because the more you use a cutting wheel, the lower the number of rpm you need, and vice versa.

The smallest grinder PROXXON LWS 100 W.

Mini grinder

although small, about the size of two or three electronic toothbrushes. The set usually includes what our client needs: various brushes, discs, grinding wheels, etc. Its main advantage is the ability to do almost “jewelry” work. This is what it was created for. So, you can process small areas without much inconvenience, especially when you can’t touch anything around. In terms of its main functions, it does not differ much from the huge grinders, maybe in scale, since what remains for our client to do are the necessary attachments. It’s not at all difficult to control; the position of the hand is, of course, easy to change, due to the small weight of the instrument. It is also easy to change the position of the instrument itself in the hand in order to provide the required image force, as it is also called the angle of influence.

READ How to Disassemble Grinder Gearbox Video

Huge angle grinders must be equipped with a protective casing and an additional handle that can change its position for ease of operation. Some models have a special gearbox that allows you to change the position of the handle without moving it to different places. Bulgarian

a small one may not have such a handle, since it fits comfortably in the hand and does not require much effort during operation.

It is necessary to keep in mind and follow safety rules when working with an angle grinder, since both the large grinder and the small grinder are among the most traumatic tools. Safety glasses should be used when working with it. The annotation for the grinder indicates the area of ​​its implementation, the clear diameter and thickness of the circle that needs to be used.

For those who ask for the introduction of their own type of discs, incorrect selection of the circle will lead to its breakage and result in injury to you. If the cutting wheel has a maximum rotation speed, exceeding the occupied will expose you to danger. It makes no sense to use discs of larger diameter if the grinder is not designed to accommodate them.

Cordless angle grinder Bosch GWS 12V-76 Professional

If the assortment set contains a circle, but it is not clear whether it will suit the device and the work being performed, then it is better to refrain from using it. Under no circumstances should the protective cover be removed. It is always necessary to ensure that the grinder is disconnected from the power supply when replacing disks.

Under no circumstances should the electrical wire from the tool touch the cutting wheel during operation. Correct use of the tool will extend its service life and will not be dangerous to you.

Installation of a grinding machine

If you want to make a stand yourself, you can use these instructions and create a simple but effective device.

Many drawings are designed to simply weld metal parts using a special apparatus. But this provided example of a frame for an angle grinder can be made from simple wooden elements, and this will speed up the process of creating the machine.

To make the structure you must use:

• a wooden box or boards to put together the desired structure;
• hammer;
• regular or electric jigsaw;
• bolts;
• drill;
• wooden hinges.

Sequence of actions during manufacturing

1. It is best to look for a large box. If you choose a low box, you will subsequently have to bend down a lot, which will complicate the work. You save a lot of time by using a wooden box as a base, but you don't have to ruin a good box. You can put together its likeness from pieces of wood. It is enough to make one side on which the grinder will subsequently be attached, as well as the top of the machine. Any missing sides of the drawer can be compensated for using legs.
2. At this stage of production, it is best to unscrew the handle and protective casing from the angle grinder. It is necessary to make a slot in the upper part of the box where a cutting disc or other attachment will be placed. To do this, you should put the disk on the grinder and lean the tool against the wall, and then use a pencil to mark the width and length of the gap that will need to be made. You should not make it too wide, because if various elements get there, the disk will jam.
3. To make a good mount for an angle grinder, you need to attach several bars (brackets) to the wall. The first will support the tool near the base, and the second will serve as a support for the grinder near the disc. A metal eye is screwed to the top bar using self-tapping screws, which will replace the handle. Additionally, you should ensure good fixation of the angle grinder using ties, and for this you should first mark and drill holes. The tool fastening must be as reliable as possible.
4. It is worthwhile to provide for the possibility of raising the workpiece relative to the disk. It is for this purpose that you need to place a wooden shield in the upper part, close to the disk, and fasten it to the hinges on the sides so that, if necessary, you can remove it. A latch or lock is used to secure the shield.

The design can also be supplemented with protective panels, but if this is not possible, then when working it is necessary to wear a special protective mask that will completely cover the entire face. During work, do not be in the area of ​​flying fragments.

Summarizing

There are several options for making a grinder from a drill, and all of them are quite effective depending on the tasks. It is better not to try to set serious tasks for the resulting tool, but it will cope with basic ones perfectly.

It is better to work on a hard surface, because... this will significantly improve operational safety.

And the most important thing is safety precautions, because... When repurposing, you can make minor mistakes, which will later have a very serious impact.

Converting a chainsaw into an angle grinder

Sometimes it becomes necessary to cut off a pipe or corrugated sheet in a place where there is no electricity. For this, a chainsaw grinder is used, which can be easily converted using a purchased attachment.

• drive pulley or drum;
• protective casing;
• belt drive and a set of keys and studs.

To install this device on a chainsaw you need:

• remove the bar and chain;
• empty the oil tank and remove the clutch drum;
• mount the device pulley on the drive shaft of the drive sprocket;
• secure the protective device and install the belt drive;
• install the cutting disc - and the mechanism is ready to work.

The main advantage of the design is that it can be used in places where there is no electricity. When working with such a machine, extreme caution must be taken, since the chainsaw has a higher torque than a standard angle grinder. In this case, the risk of cutting blade destruction increases.

Screwdriver upgrade

If you don’t have a drill or chainsaw at hand, but you need to cut materials, you can make an angle grinder from a screwdriver. The algorithm for its modernization is almost the same as for making an angle grinder from a drill. The main element of the design will be the purchased attachment - an adapter or spindle of a faulty angle grinder.

The advantages of such a power tool include the rapid transformation of the mechanism and the ability to use it away from the electrical network. The homemade product can be used in cramped conditions where a standard angle grinder is not suitable due to its large size.

The main disadvantages of a homemade device are:

• short battery life (when using a cordless screwdriver);
• low rotation speed of the cutting disc - about 700 rpm;
• insufficient power of the electrical device.

Such a mechanism can only be used as a low-power angle grinder. With its help you can cut metal with a thickness of no more than 1.5 mm or a 20*20 corner. They can cut reinforcement with a diameter of less than 8 mm. Using a screwdriver as a full-fledged cutting tool will not work.
