Do-it-yourself 12V grinder
A grinder in the hands of a master can work wonders. It is used to cut material, sharpen tools, and polish parts. But there are situations when there is no 220 V network or it is located far away and there is not enough cable to connect.
A homemade grinder operating on 12 V will help out, which can be connected to a small battery or to the car’s network. The advantages of such a tool are its quiet operation, which allows you to use it without fear of problems with your neighbors.
The homemade product is driven by an electric motor 775, operating from 12...24 V. It has a cooling fan, the armature is located on bearings. All this makes the motor long-lived even with active use.
In addition to the electric motor, prepare: an adapter for an angle grinder; connector through which the power source is connected; paint; switch; wires; self-tapping screws; cogs. The body is made from various PVC parts used for installing water supply, sewer, and electrical networks. Tools used include a hacksaw, glue, drill, caliper, drill, and marker.
For the body (handle), PVC parts are prepared: a piece of pipe; 90° connecting angle; adapter for smaller diameter. The adapter is glued to the corner, then a piece of pipe is glued to its free end. Get an elegant handle.
They make a protective shield that will protect the worker from sparks and disk fragments. Use a PVC plug with an 11 cm diameter. A hole is drilled in its center with a diameter equal to the size of the part protruding from the engine housing (next to the shaft outputs). On the sides of it there are two more holes for mounting screws. Through the latter, the engine is attached to the shield.
Using a grinder, cut off a segment (approximately 3.5 cm high) of the protective cover, forming a working area for the disk. In this case, the mounting holes must be parallel to the cut and remain on the part.
Cut a piece of PVC pipe. Glue it to the outside of the protective cover so that the segment does not interfere with the installation of the motor. In the craft, it will be located inside this segment, which, in addition, ensures the connection of the knot with the free end of the corner in the handle.
At the free end of the corner of the handle, closer to the bend, a series of holes are arranged in a circle, which will ensure heat removal from the running engine. To it, closer to the edge, an additional short handle from a piece of pipe of a smaller diameter is glued vertically.
The surfaces of all plastic parts of the handle and protective shield are painted with aerosol paint. The color is chosen from those you like.
The engine is secured with screws from the back of the protective casing. Insert the latter into the free end of the corner on the handle - connect the parts with screws (better, it allows you to disassemble the tool in the future), by gluing.
The end of the handle is closed with a plug in which a switch and a power connector are placed. Suitable holes are pre-arranged for these parts; installing the connector with glue. Before installing the plugs, solder the wires coming from the engine to the connector.
The motor shaft is equipped with an adapter, securing it with a screw having a hex head. Secure the disk and try to work.
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:
- Choose an attachment for your future grinder.
- 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.
- Fix all parts.
A frisky, unusual method for creating an angle grinder
There is no second, more difficult method to achieve the desired result.
- 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.
- 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.
- 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.
- 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.

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.
DIY mini drill
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.

Grinder 12 volt + (Video)
In order to use an electric tool on the road, it is necessary to convert its power of 12 Volts to 220. Thus, you can power it from a car in which a direct current with a voltage of 12 Volts flows, by installing a special invector.
The process of connecting an angle grinder to a 12-volt battery
Low-power invectors should be connected to the cigarette lighter; there are no special requirements here. The only nuances are:
- Use under temperature conditions 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, unobstructed air flow is necessary.
What you can make with your own hands from a screwdriver
These design features, as well as technical characteristics, are important. It depends on them what kind of homemade products you can assemble from a screwdriver. All household appliances and power tools run on electricity. In this case, the work is performed by electric motors of different designs and power. They are powered by alternating or direct current.
Cordless angle grinder made from screwdriver parts.
And therefore, it is quite possible to assemble the following technical devices using a screwdriver or from some of its parts:
IMPORTANT! If the impact type model is powerful, then you can use it to make a concrete tamper using a special attachment. It will take you time to implement each option. It will be different. You also need to be prepared for additional costs. By the way, they are insignificant. In some cases there will be no cost at all.
How to quickly make a grinder from a drill?

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 make a grinder from a drill?
Hi all! In today’s article I will tell you how to make an angle grinder (angle grinder) from a drill so that it can not only drill, but also, for example, cut metal.
How to make a grinder from a drill You only need a simple attachment
But first I will try to dissuade you from this matter. Why? Well, because I believe that each tool is intended only for its own purpose and trying to give it the functions of another, firstly, does not provide a 100% replacement, and, secondly, almost always leads to unsafe operation.
If we talk specifically about our case, then most drills produce a maximum of 3000 revolutions per minute, while for working with a small disk, grinders reach 11,000 revolutions per minute. That is, sawing will not be as effective.
As for safety, it is worth remembering that the cutting wheel on an angle grinder is surrounded by a protective casing, thanks to which sparks and fragments cannot fly in all directions, and it also protects if the disc suddenly gets caught and it breaks. There is no way to fit the casing onto the drill, so safety will be at risk.
If the above reasons do not stop you, then read on.
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.
How to make a wall chaser with your own hands
It will be useful for many home craftsmen to learn how to make a wall chaser with their own hands.
A wall cutter is a device designed for laying grooves - grooves into which electrical wires, pipes and other communications are laid.
It is almost impossible to do without gating when building a new house. Even in an already built home, there is often a need to lay grooves, for example, when moving sockets or switches.
The wall chaser, unlike the grinder, is equipped with not one, but two paired discs.
Of course, if the grooves are short, you can use a chisel with a hammer, otherwise you cannot do without a specialized tool. If you don’t have a power tool, a manual wall chaser will help out. An example of such a tool is given.
The design of such a manual device is extremely simple - it is a piece of pipe with a welded handle. A cutting part is attached to a straight section of the pipe, which during operation is driven into the material being processed. The wall chaser shown in photo 1 is designed for processing horizontal surfaces. To work with vertical surfaces, the handle is not curved, but straight.
To make the cutting head, you should use carbide material, preferably with additional diamond coating. The groove is carried out along the intended lines by periodically moving the cutting head. You should start working carefully, with careful movements, so as not to stray from the intended direction. This tool is especially effective for aerated concrete masonry.
Homemade electric wall chasers
Photo 1. The design of a manual wall chaser is extremely simple - it is a piece of pipe with a welded handle.
An electric wall chaser is a very useful and convenient tool, but few people buy it even when building a new house.
The tool is quite expensive and highly specialized, so its purchase is unlikely to be justified.
Hammers or drills with a drill of a sufficiently large diameter are often used for grooving, but working with them is not very convenient, and the quality of the grooves leaves much to be desired.
But, as it turns out, there is a real opportunity to turn a hand-held power tool into a fairly high-quality wall chaser with minimal material costs.
A relatively simple device, an example of which is shown in the figure mentioned above, allows you to make the work both simpler and of higher quality. If you use a wooden or metal strip as a guide, you will get a groove that, firstly, is quite straight, and secondly, it has the same depth along the entire length.
How to create a beautiful landscape design yourself?
How to make a wall chaser from an electric drill
To turn an ordinary electric drill into a simple wall chaser, just fix a cutter of a suitable shape and the required size in its chuck. An example of such a cutter is shown in the upper right corner.
The grooves can be cut with such a tool without any additional devices.
But working with such a device is not very convenient, and in this case the groove turns out to be of poor quality - with uneven walls and varying depth.
Wall chaser from an angle grinder
A professional wall chaser (or its household version) is very similar in operating principle and often in appearance to an angle grinder. In both cases, the cutting elements are diamond discs. The wall chaser, unlike the grinder, is equipped with not one, but two paired discs.
Wall cutter device.
Thanks to this device, it makes two slits at the same time. The distance between them determines the width of the groove. The slots have a fixed depth. To remove construction dust arising during operation, the industrial unit is equipped with a dust collector.
Even in the household version, a wall chaser is a fairly expensive device, so home craftsmen prefer to replace it with a grinder. For this purpose, it can be used even without modifications, making two slots in succession. The quality of the groove, of course, leaves much to be desired.
Relatively simple modifications allow you to turn an angle grinder into a homemade wall chaser.
It is easier and safer to work with such a unit, and the quality of the groove is higher - it turns out more even, with clean edges. To manufacture the fixture, some technological steps are required.
You will also need financial investments, but they are many times less than the cost of the cheapest specialized wall chaser.
The process of adapting the grinder to two cutting diamond blades looks like this:
- In the traditional way, one of the disks is attached to the machine.
- Another fastening nut is selected, equipped with an additional ring of the same diameter as the main one. It will fix the second cutting disc.
- The second disk is placed on the main nut and clamped by the second nut, which is turned upside down. The main thing is that there is enough remaining thread.
- If an extended nut or bushing of the required length is placed between the cutting discs, the distance between them can be changed. Due to this, the width of the cut groove will change.
There is a lot of dust when a wall chaser is working using an angle grinder. This problem can be resolved in two ways:
- the use of respirators and systematic ventilation of the room;
- purchasing or manufacturing a protective casing with a pipe to which the vacuum cleaner hose is connected.
When working with any of the described tools, basic safety rules must be strictly observed:
- working tools (especially those with an electric drive) must be in good working order;
- you cannot work without protective devices that protect your eyes, hands and respiratory organs - safety glasses, gloves and respirators;
- Before starting work, you need to make sure that there is no electrical wiring connected to the network under the surface being treated;
- when working at height, the support must be stable and reliable;
- You can cut walls at a distance of at least 15 cm from doors and windows and 40 cm from gas pipelines.
From the description it is clear that there is nothing complicated in making a tool for scoring.
The main thing is to have patience and minimal basic skills for such work.

Making an angle grinder from a screwdriver
There are many options for how to remake an instrument. The easiest way is to use ready-made or homemade attachments or adapters. We fix one end of it in the cartridge. You need to attach a disk to the second end.
You can also convert a drill-driver into an angle grinder using a special type of attachment, which is equipped with a gearbox. To do this, we disassemble the power tool, dismantle its gearbox and install an attachment instead. And you have in your hands a tool that is very similar to an angle grinder.
Purchasing such a special attachment will not be cheap. And modification will take a lot of time. To make homemade nozzles, use studs of suitable diameter, nuts, and washers. They can even be used with cordless electric screwdrivers.
IMPORTANT! Of course, homemade ones are less effective compared to factory grinders. The difference in rotation speeds of the nozzles is large. Approximately 3000 rpm for a screwdriver versus 11000 rpm for an angle grinder. Low power coupled with low speed significantly limits the functionality of a DIY device.
READ Do-it-yourself wood trimming
DIY devices are recommended for use only in emergency cases. Since reversal is possible on the tool being remade, in order to avoid injury it is necessary to control the direction of rotation of the disk.
Practical attachments for grinders and screwdrivers
Hello, dear readers of the Uspei website. Today we have a new selection of interesting attachments for grinders, drills, screwdrivers and other power tools that will help speed up your work. An attachment that will turn your grinder into a woodworking tool. As a result, you will get a chisel, but not a simple one, but an electric one. The chisel is intended for hollowing out holes, grooves, nests and other things in a wooden surface. Working with a conventional chisel is very labor-intensive and takes a lot of time. With this attachment you can significantly speed up the process. The chisel can be used to process both hard and soft wood. The device can be used to make technical holes, for example, in the manufacture of furniture.
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.

Operating principle and main components of the drilling machine
A drilling machine is a well-structured product. Firstly, the bed. As a rule, this is a steel plate (but for small devices it can be made of light alloy) on which the entire product is mounted. A stand is installed vertically on the edge of the bed farthest from the master. The working part, consisting of a motor, a working head with a cartridge and, if there is one, a transmission, moves up and down along it and turns left and right. The head on the stand is fixed in the required position by a locking mechanism. And precise positioning of the height of the spindle with the chuck and drill is performed with a special handle.
Professional drilling machine
The motor and work spindle can be located on both sides of the stand. In this case, a belt drive is organized on several pairs of pulleys between the motor shaft and the working spindle. By throwing the belt from one pair to another, they set different speeds of rotation of the working body - the drill.
Drilling machine with pulleys and belt drive
Another option is to mount the cartridge on the motor shaft. The design is simpler, but the speed of rotation of the drill must be adjusted by changing the speed of rotation of the motor, and this requires an electrical or electronic circuit.
Drilling machine with chuck on motor shaft
The working tool is a drill. Drills are classified by size and purpose. In the practice of home-made workers, diameters from 0.5 mm to 12 - 18 mm are used. Drills are selected for work on wood, plastic, hard and soft metal, and concrete. They will differ in the sharpening geometry of the working end and the presence or absence of hard surfacing at the end.
Drill
The machine works this way. The motor turns the working spindle, at the lower end of which the chuck sits. There is a drill clamped in it. With rapid rotation and pressure on the surface from top to bottom, the drill cuts into the material with its cutting edges.

How to make a drill press using a drill
Using an electric drill is probably the easiest option for making a homemade drilling machine, because... in this case, the issue of fixing the drill is resolved (a drill chuck is used), and an electric drive is also provided. The main problem in this case that needs to be solved is the manufacture of a frame and a mechanism for moving the drill in a vertical plane. All work can be divided into several stages that determine the nature of their implementation: preparatory, execution of work and final.
The metal stand for securing the drill is easy to manufacture and convenient to use.
Preparatory stage
During this period of work it is necessary:
- Decide on the materials and components that are available and that can be used to manufacture the machine: wood or metal, spare parts for cars, motorcycles or household devices, electrical wires and switching devices, as well as protective equipment.
- Depending on the selected materials, the necessary tools are prepared. This can be a grinder and a welding machine (inverter), a circular or circular saw, as well as carpentry tools and fasteners.
- A drawing (sketch) of the structure being created is developed, with the main dimensions being: the mounting location of the drill used and the size of the drill movement.
Wood structure is not strong enough, but can be fully used for making printed circuit boards
Execution of work
Having decided on the materials and tools, as well as having prepared them and developed a drawing, you can begin manufacturing. Below are step-by-step instructions for making such equipment using a metal sheet and profile.
Illustration | Description of action |
The base (plate) of the machine is made from a metal sheet 10-12 mm thick, on which holes are drilled for its subsequent fastening. A metal profile (stand) with a cross section of 40×40 mm is welded to the plate. | |
When installing the profile, check that it is strictly in a vertical plane to ensure the correct movement of the drill in the future. | |
A workpiece is cut out of a metal profile with a cross-section larger than the welded stand, after which the possibility of its movement along this stand is checked. | |
A cut is made on the workpiece along its entire surface. | |
After this, a metal structure is made from a profile of a similar cross-section, into which the bicycle sprocket is placed. | |
A bicycle chain is fixed to the surface of the vertical stand using welding. | |
The ability of the assembled structure to move along the rack is checked. | |
A fastener is cut out of a metal pipe with a diameter larger than the chuck of the drill being used, which is welded to the previously assembled structure. | |
The reliability of the drill is checked. | |
From a profile of a smaller cross-section, levers are made that serve to drive the movement mechanism, which are mounted on a previously assembled structure. | |
The functionality of the lifting and lowering mechanism is checked. |
Final stage
At this stage of work, the following activities are performed:
- the assembled metal structure is painted;
- moving units are lubricated;
- For ease of use, a plug socket can be installed on the stove to plug in an electric drill with a connected electric cable that serves to connect it to the network.

How to make a grinder from a drill
Hi all! In today’s article I will tell you how to make an angle grinder (angle grinder) from a drill so that it can not only drill, but also, for example, cut metal.
But first I will try to dissuade you from this matter. Why? Well, because I believe that each tool is intended only for its own purpose and trying to give it the functions of another, firstly, does not provide a 100% replacement, and, secondly, almost always leads to unsafe operation.
If we talk specifically about our case, then most drills produce a maximum of 3000 revolutions per minute, while for working with a small disk, grinders reach 11,000 revolutions per minute. That is, sawing will not be as effective.
As for safety, it is worth remembering that the cutting wheel on an angle grinder is surrounded by a protective casing, thanks to which sparks and fragments cannot fly in all directions, and it also protects if the disc suddenly gets caught and it breaks. onto the drill , so safety will be at risk.

Neither a garage nor a private yard can do without an angle grinder - an angle grinder. The grinder belongs to the category of instruments that have a high degree. The need for a miniature instrument exists where a person is engaged in manufacturing. This device is suitable for those who are engaged in modeling - they often have to cut parts from hard materials.
Some of us have a common mine abyss credited to the emancipation of the Dobrolyubov ham ball, ordered by the Russian metropolitan supporter Lukas Sakharov. By making a mounting saw with your own hands from a grinder, you can not only protect yourself when working with this power tool, but also significantly increase the quality and productivity of your work.

It is suitable for cutting metal, stone, tiles and grinding surfaces. The angle grinder angle grinder or angle grinder, which has received the unofficial name grinder , is one of the most common.
And instilling patriotism and electricity into the company for removing just the oblivion erotica mod is boring, that is, push the mine out of the majestic fragmentation of st basil's cathedral.
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.
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.
Smooth start, blade change and tool weight
The main purpose of a soft start is to reduce the load on the electrical network when the electric wood saw is turned on. The higher the power of the tool, the more important it is to have this function. This also applies to battery models.
Quickly changing saw blades is important when working with different materials. There is a so-called keyless replacement, in which you can remove and install a new blade by simply pressing a button.
Since a reciprocating saw is a hand-held tool, its weight plays an important role in the process of use. The larger it is, the more difficult it is to use the tool; when work is carried out for a long time, your hands get tired faster.
Screwdriver machines
Craftsmen have made many different types of machines from screwdrivers . They cope well with everyday tasks.
If you need to work professionally, then you cannot do without more serious equipment.
One of the options for how to convert a drill-driver into a drilling machine is demonstrated in the video below.
A method for creating a simple lathe is shown in the video below.
It is also possible to assemble the simplest milling and grinding machines based on a drill-driver, which is demonstrated in the following videos.
What can you make from a screwdriver with your own hands?
A screwdriver is widely used in various fields of activity to work with various types of fasteners: self-tapping screws, screws, bolts with nuts, furniture confirmations, screws and others. This power tool can also be used to drill holes in various materials, for example, in various metals, lumber, and concrete. In this case, the functionality of the model being used is determined by the magnitude of its power and torque, and the presence of a shock function.
From a screwdriver you can make a variety of equipment and tools for household use at home. In addition to the power tool itself, conversion in many cases will require additional parts and materials. But homemade devices will still cost less than their factory counterparts, making it possible to automate and make manual labor more efficient.
Advantages and disadvantages of homemade lawn mower designs
They depend on the parts used for assembly.
The main advantages include:
- environmental friendliness;
- low cost (since you can use any household appliance);
- noiselessness (if an asynchronous motor is used).
Low noise is undoubtedly an important indicator, but considering that any lawn mower, including a homemade one, makes manual work incredibly easier, it can be tolerated, so any other motor will do.
It is not recommended to use a vacuum cleaner motor due to its rapid overheating. If there is no other one, you can use that too. And fight overheating with the help of a proper casing made of metal mesh or with holes for air circulation.
The disadvantage of a homemade tool is that the knife is not adjustable in height. But, with certain skills, this can be corrected.
Converting a screwdriver into an angle grinder
If the angle grinder is broken or is missing altogether, then it can be temporarily replaced with a cordless or corded electric screwdriver. However, there are various options for remodeling. The easiest way is to use ready-made or homemade attachments or adapters. An example of an adapter is shown in the photo below. One end of it is fixed in the cartridge, and a disk is attached to the other.
Another option that allows you to convert a drill-driver into an angle grinder is to use a special type of attachment equipped with a gearbox. When implementing the method, the power tool is disassembled, its gearbox is removed, and an attachment is installed in its place. After the transformations, you will get a tool similar in appearance to an angle grinder.
It should be taken into account that such a special attachment is expensive, and modification work requires a lot of time.
Homemade nozzles are made from studs of suitable diameter, nuts and washers. They are even used with cordless electric screwdrivers.
The efficiency of homemade grinders is significantly lower than that of factory grinders. This is due to the large difference in rotation speeds of the attachments: approximately 3000 rpm for a screwdriver versus about 11,000 rpm for an angle grinder. The insignificant amount of power together with the low speed significantly limits the functionality of the device.
The devices made should be used only in emergency situations. Due to the possibility of reverse on the tool being remade, it is necessary to monitor the direction of rotation of the disk so as not to injure yourself.
