What can be made from a screwdriver: an electric bicycle, a boat motor, DIY crafts from an old engine

Lifting mechanism for impeller

The use of a lifting mechanism in the motor allows not only to control the movement of the boat, but also, if necessary, to raise the propeller above the surface of the water.
Ideally, such a device should provide rotation of the screw in both horizontal and vertical planes. The simplest and at the same time the most effective design could look like this: a motor is attached to the transom of the boat using clamps. The clamps are rigidly attached to a plate or square, and have rings into which a tube is threaded with a guide welded to the middle perpendicular to the axis, into which the motor shaft is threaded.

This hinged solution is quite simple and does not require additional, complex solutions.

Converting a screwdriver into a trimmer or lawn mower

To make an electric scythe with your own hands, you will need the following parts and materials:

a piece of plastic pipe about 2 m long;
soldering iron with soldering kit;
fasteners: self-tapping screws, bolts with nuts;
45 degree plastic corner;
pipe plug;
12 V motor from an electric screwdriver and a battery from it;
the wire;
adapter from 40 to 50 mm for plastic pipes;
power button;
plastic bucket;
contact clips (crocodiles) – 2 pcs;
blades from stationery knives.

The conversion process is carried out as follows:

Having disassembled the electric screwdriver, take out the motor;
attach it to the plug, having previously marked and drilled mounting holes in it;

attach the electric motor with 2 screws;

solder the output to the motor;

install the electric motor by inserting its wiring into the pipe;

mark the location of the future switch with a marker on the tube;

drill a hole;

connect to the wiring switch, mount it;

contact clamps are attached to the ends of the outgoing wires to allow quick connection to the battery;

a battery holder is made from the adapter;

connect the drive, connect the adapter to the tube;

make knives from blades;

using a conventional terminal clamp, the nozzle is connected to the motor shaft;

a protective casing is made from a plastic bucket;

glue the part to the pipe;

check the functionality of the structure.

The created device will allow you to mow only grass with soft stems.

There are many different options for lawn mowers based on networked models of drills and screwdrivers. The photographs below show two homemade products.

First, a base is created from metal, plywood or other materials, to which wheels are then attached, as well as a control handle. The electric screwdriver is secured with clamps or to the stand. A cutting attachment is inserted into the chuck. To protect the feet from flying grass, a cover is attached to the back of the base. Power is supplied via a button or directly from the network.

A cordless or corded model of an electric screwdriver can be turned into an engraver, which is also called a dremel, drill, mini-drill, or straight grinder. To do this, you just need to buy a nozzle in the store.

and grind any bat to fit it.

A homemade chuck will allow you to use a variety of accessories designed for Dremels.

The following video demonstrates the process of creating a flexible shaft engraver.

Complete analogue of the factory “Dremel”

The original housing is also made independently in such a way that the engine is tightly fixed inside, while leaving a gap or an open part in the heating area.

The body of the mini-drill can be any plastic tube.

There are models that used a tube of sealant, a syringe, a plastic tube of toothpaste or children's candy.

A piece of plumbing plastic pipe cut to the required length will also work, but in this case the open ends will need to be sealed with some kind of movable “plug”, for example, acrylic or cut out of plastic.

The resulting tool is a universal option; Depending on the type of repair, various attachments are fixed with such a clamping chuck: drills, cutters, discs with a cutting edge or screwdriver heads.

Wood lathe

Creating products from wooden blanks is impossible without a woodworking machine. As a working surface of the machine, you can use a workbench made of wood with a flat surface.

According to the dimensions of the tool, make a bed from a lath in which the screwdriver will be located and fixed. A regular clamp is used for fixation. The bed is attached to the base using self-tapping screws or a clamp.

A mandrel with teeth is placed in the screwdriver chuck. To make the tailstock, 2 bars with an adjustment screw, sharpened to the dimensions of the cone, are suitable. The headstock is attached opposite the screwdriver. In this case, its axis should be at the same level with the headstock adjusting screw.

Use a clamp to secure the back stop to the base of the future machine. A simple wood lathe is ready to use.

How to make a drill with your own hands: assembly instructions and video

Many home craftsmen are interested in the question of whether a drill can be made with their own hands. Solving this problem is not difficult, and the finished home-made device, despite the simplicity of its design, will be distinguished by fairly high efficiency and functionality.

Homemade drill based on a small-sized electric motor

A homemade drill will not cost much and will not cause any problems during manufacture. It will be useful in many situations, including when performing such technological operations as:

drilling;
drilling holes;
processing of grooves and recesses of various configurations;
engraving;
polishing;
cutting of plastic products;
cutting non-ferrous sheet metal (aluminum, brass, bronze, etc.) up to 1.5 mm thick.

Grinding a metal part with a drill

The drill, made according to the instructions below, is distinguished by its compact dimensions, light weight and ease of use.

Such a device, made by hand at home, is equally successfully used to perform small and quite serious work with products made of various materials - metal, wood, plastic, bone, etc.

Such a drill is very useful in jewelry making, when repairing small items for various purposes, manufacturing and repairing electrical devices, and in many other situations.

Salute to everyone!) In short, I had a screwdriver, it worked properly for 4 years, it never failed, but then the battery began to run out quickly, it lasted about 5 minutes, then the charger died... the engraver recently caught fire, there are hard-to-reach places on the car that you can’t reach with a screwdriver or a drill , but of course I feel sorry for the money for this crap))

I disassembled the screwdriver, pulled out the motor with the regulator and the pronto, brought out the wires. Powered it from the power supply from the computer. The case was made from 2 covers from the Ax)))) well, whatever was at hand was the main thing))) the case turned out to be surprisingly very good , fits perfectly in the hand! Overall I’m happy)

Bulgarian

If you don’t have a grinder, you can replace it with a homemade grinder made from an old screwdriver. To do this, use a nozzle or adapter equipped with a gearbox, which can be purchased ready-made. The possibility of making such devices with your own hands cannot be ruled out. For this, studs, nuts and washers are useful, the diameter of which is similar to the diameter of the screwdriver chuck.

After disassembling the tool body and dismantling its gearbox, insert the end of the nozzle or adapter into its chuck in place of the gearbox. Having assembled the body of the new tool, the homemade angle grinder is ready for use.

Required materials and tools

The materials and tools when remaking a screwdriver completely depend on the type of tool and the type of power source, as well as its features. But if we generalize, we can highlight several main tools:

screwdrivers;
pliers;
knife;
insulating materials;
cable for supplying electricity;
soldering iron and materials for soldering;
some kind of housing for the future power supply.

Reworking purchased blocks

You can also power it from any other purchased power supplies. The conversion process in this case will be almost the same, however, in addition to the resistor, you may need to solder in additional diodes. The most important thing is to achieve the required output parameters. And this can be easily done using a combination of components.

We use a laptop charger

An excellent option is to use a laptop charger. Such devices usually operate with a voltage from 12 to 19 V. This is quite enough to ensure high-quality operation of the screwdriver . But do not neglect the output current indicators. The closer it is to what is required, the better.

In this case, converting a screwdriver to mains power comes down to simply soldering the wires from the charger to the board in the tool. It is advisable to insulate everything using electrical tape or other similar materials. After this, the wire is brought out and the tool can be used.

Refinement of lawn mowers

The boat motor from the trimmer requires a little modification to get a workhorse for the watercraft. The advantage of gasoline trimmers is their low price and maintainability. Homemade motors for boats based on gas trimmers have a built-in tank, shaft and gearbox. You can look for a special conversion kit, which will contain a stainless steel propeller and drive, as well as a set of adapters for the trimmer shaft. Often there are kits with a clamp for installation on the transom, so there will be no problems with fastening to the boat. If you follow the included instructions, you can convert a boat motor from a lawn mower in 20-30 minutes.

More skills will be required from the angler if he decides to radically change the design of the trimmer. In this case, there is huge scope for imagination and ingenuity. One option involves making a vertical leg.

To rotate the shaft 90 degrees relative to the engine, you will need a gearbox from an angle grinder.
The existing trimmer tube must be shortened using a cutting machine. It is better to replace the bushings inside with bearings.

A simple screw can be made from a strip of duralumin 10x30 cm, 2 mm thick. By attaching a stencil with a two-bladed screw to the workpiece, you need to make markings. You can cut the screw using a grinder and a chisel. The edges must be processed with a file. Place the plate on a flat surface and bend both blades to a height of 1 cm.

A hole is drilled in the center to connect to the shaft. To prevent the blade from touching the watercraft's cylinder during rotation, it is better to make a ring attachment. The trimmer-based boat motor is ready, you can go to the pond.

Power supply for a screwdriver: preparation for conversion

Experienced repairmen advise placing the power supply for the screwdriver inside the product. This way, dust, dirt, and liquids will not get on it, which means the element will last longer. At this stage you need to open the collapsible housing. To open, take a penknife and go along the seam.

open the screwdriver to install the power supply. Run it along the connecting seams to loosen the fastenings

to understand where to place the power supply;
find out what voltage you will be working with (there is a marking inside, usually 12-18 volts );
determine the installation method.

At this stage, you should think about what you will use to create a new power supply.

Generator

Cordless screwdriver models are perfect for creating a homemade generator. By rotating its handle, the device will be able to supply electrical energy. Such a generator can be used during a camping trip or when there is a power outage in a country house. A homemade generator can be used to recharge batteries (6-12V).

A screwdriver with an operating voltage of 18 V or more is suitable for the job. Craftsmen advise following the following sequence of actions:

Disassemble the screwdriver body.
Unsolder its electrical board.
In place of the battery, install a diode bridge that is suitable in terms of technical parameters and characteristics.
Make an easy-to-use handle by securing it in the screwdriver chuck.

Once these simple modifications are completed, all that remains is to assemble the body. The homemade generator is ready to work.

Economical option without housing

The most budget model of a mini-drill is a regular electric motor, to which a power unit is connected through wiring without a housing.

A 12-volt motor will require a power supply consisting of a 30-watt transformer and a rectifier bridge, for example, on a 1N1007 diode.

The inclusion of a simple capacitor in the circuit, up to 25 V with a capacitive characteristic of 1000 microfarads, will protect the motor from pulsating oscillations of the winding during voltage rectification.

The chain works reliably, but as the load increases, for example, when drilling dense material, the voltage will drop, which will lead to a stop in rotation. The voltage can be stabilized by adding stabilizers to the KR142EN8B or L7812CV circuit

After the drive unit is ready, a chuck is made or purchased - even a pen rod in which the drill is fixed with glue can be suitable for home drilling of miniature holes. The cartridge can also be replaced with the previously proposed collet or screw terminal.

Assembling a manual camping electric generator and a homemade wind generator

Using battery-powered models of the tool, it won’t be difficult to make a homemade generator that will produce electricity when you rotate the attached handle by hand. This device will come in handy when traveling. To make a dynamo, you do not need to radically modify the product. Everything necessary to create a camping generator is already included in the design of the device; only minor modifications will be needed.

Using the created equipment it will be possible to charge 6 or 12 V batteries.

For remodeling, a power tool with an operating voltage of 18V or higher is suitable. The modification is carried out in the following way:

disassemble the electric screwdriver;

carefully unsolder the electronic board;
instead of batteries, they install a diode bridge that is suitable in terms of parameters (dimensions, technical characteristics) inside the battery case;

make a comfortable handle with a handle;
the end without a handle is secured in the chuck.

The final design after the manipulations will look something like the photo below.

A diode bridge is necessary so that the handle of the electric generator can be turned in any direction. Instead of a handle, you can insert a nozzle with blades. Then you will get a simple wind generator.

An electric generator powered by wind power is also made in a different way, in the form of a weather vane. In this case, do the following with the battery device:

disassemble the screwdriver;
take out the electric motor by disconnecting its contacts;
remove the cartridge with gearbox (rotor part);

the electric motor shaft is inserted into the cartridge, clamping it;
a round metal plate about 1 mm thick is bolted to the gearbox gear, which will serve as the basis for fixing blades made, for example, from plastic pipes;
a clamp with a clamp is placed on the shaft between the chuck and the gear;

cut out a rectangular base from plywood or thin metal;
using a clamp with a clamp, attach the engine with the cartridge to it, drilling holes for the mount in the right places;

they make a casing to protect the wind generator (from precipitation, dust and other unforeseen influences), for example, from under a coffee can;
insert the base with the motor and cartridge inside, securing the elements with glue, and the cover with sealant;

blades are made by attaching them to the round plate of the unit;
make a weather vane;
the assembled generator is mounted on one of its ends;

connect the wiring to the motor outputs;
use a multimeter to check the output voltage by rotating the blades by hand.

There are many options for wind generators. They even attach the entire screwdriver to the support, equipping it with an attachment with blades.

⚒ Do-it-yourself hand engraver from a drill: step-by-step instructions

Very often, a home craftsman is faced with the need to make a small notch on a metal or wooden part, engrave on a keychain, or polish a hard-to-reach place.

In such cases, bulky power tools cannot be used, so you have to turn to specialists and pay for their services.

Today we offer our respected reader a simpler solution to a similar problem, which the author of the “MAGYOM” channel describes in his article.

That's all you need to make a hand engraver PHOTO: .com

A little about the hand engraver: purpose, features of the tool, necessary materials

A hand engraver, popularly called a drill, is a universal power tool that can perform the tasks of an angle grinder, engraver, drill or even a milling cutter.

However, its peculiarity is that it makes it possible to work with very small parts and in hard-to-reach places. To make it in a garage or workshop you won’t need a lot of material, although you will have to purchase some parts.

But the final cost of the device will not exceed 200 rubles, which is good news.

Let's start with what is needed to make it.

An old clutch or brake cable from a motorcycle (can be found in almost any garage).
A used foam gun.
Mayevsky's tap and a long screw that will be screwed into it.
2 bearings with an internal diameter slightly smaller than the screw.
A copper or steel tube is a car brake line.
Solder wire.
Hacksaw for metal.

A conventional drill will be used as a drive. In addition to the above, you need to prepare a grinder, a blowtorch, a hammer and sandpaper.

Preparing parts for the future drill

You should start by making a tube from a long screw. To do this, you need to clamp the drill in a vice (this must be done by the handle; under no circumstances should you clamp it by the body).

A bolt without a head is fixed in the chuck, and a Mayevsky tap is screwed onto its threaded side - it will be used as a guide.

Afterwards, a drill is selected that fits the tap hole, the drill is turned on and the screw is drilled exactly in the center to the maximum possible length.

The screw must be drilled in the center for the entire length PHOTO: .com

Further work requires extreme care.

Using two needle files, between which the screw clamped in the drill chuck will rotate, you need to remove the thread so that bearings can be mounted on the resulting sleeve.

At the same time, about 6-8 cm of undamaged thread should remain on the side closest to the cartridge - this is very important.

Using needle files, the screw is ground to the required diameter PHOTO: .com

Assembling the internal part of the engraver mechanism

Having sawed off the screw along the edge of the thread, we screw the Mayevsky tap onto it and put on the first bearing almost all the way, holding the sleeve in a vice. Next, the tube is put on, and then the second bearing fixes it. The inside of the drill is ready.

We put bearings and a tube on the shaft PHOTO: .com

Working with a spray foam gun

This tool only requires an outer long tube. You need to cut off a section from it, the length of the finished inner part without the Mayevsky tap, adding 2 cm. This will be the shell, which will serve as the handle of the engraver.

The tube of the required size is measured and cut PHOTO: .com

Manufacturing a collet mechanism for clamping cutters

To make a mechanism capable of holding thin drills or cutters, you will need a hacksaw for metal. The finished shaft is secured in a vice and a cross-shaped notch is made on the side of the remaining thread, along its entire length. Now, if the Mayevsky tap is tightened, the resulting petals will shrink.

The Mayevsky tap itself is ground into a cone for ease of working with the engraver.

We grind the Mayevsky tap to a cone, after which it will be much more convenient to work with it PHOTO: .com

Flexible shaft manufacturing work

Here you must first free the cable from the sheath, but you cannot throw it away - it will be useful later.

The assembled internal part of the rotation mechanism is clamped in a vice, after which one edge of the cable is inserted into a sleeve made from a bolt.

Now you need to heat the resulting connection and fill the internal void with molten tin. A blowtorch will help with this work.

The sleeve with the cable warms up, after which molten solder begins to seep into it PHOTO: .com

All that remains is to tighten the bearings, make sure that the connection is good, after which you can continue assembly.

The connection is checked and the bearings are pressed as tightly as possible PHOTO: .com

Next, a piece of tube cut from a spray foam gun is placed over both bearings. In fact, the rotation mechanism itself can be considered complete. All that remains is to protect the operator.

The tube is placed over the bearings almost close to the tip PHOTO: .com

Protection of the master when working with a drill

Now you need to put the cable housing back in place, but this is not easy to do. After the tips are cut off, the cable begins to unravel. Here the same solder and blowtorch will come to the rescue.

The casing is put on the cable and pulled until it stops. Due to the fact that the outer tube is slightly longer than the inner one, the protection goes inside.

The reverse side of the cable is placed in the brake pipe and pressed in with a hammer.

Crimping the reverse edge, which will be clamped into the drill chuck PHOTO: .com

The final touch: groove for a wrench

In order to tighten a cutter or drill in a collet chuck, you will need to ensure that the wrench can work with both the shaft and the tip. If there were already edges on Mayevsky’s tap (they remained on the edge), then they need to be made on the bushing. This issue is easily resolved with a flat needle file.

Briefly about the manufacture of cutting cutters

It is quite simple to make such consumables, and therefore it will be more convenient to show it exclusively with photographic examples.

Summarize

The work of making a hand-held electric engraver from a drill with your own hands is not too simple.

However, if a home master nevertheless decides to take it up and completes it, then he will receive a unique tool that will always be useful. It is unlikely that such a device will remain idle.

And if you compare the cost of such a factory-made product, then the importance of such an engraver in your eyes will increase significantly.

Homemade boat motor from a walk-behind tractor

If the previous option is considered low-power, then the device from a walk-behind tractor is the opposite. Equipment for working with land, as a rule, has reliable four-stroke internal combustion engines. This DIY boat motor is capable of carrying passengers even against the current at an impressive speed.

True, a decent volume does not allow installing such structures on PVC boats. At least on small ones. The principle of how to make a boat motor from a walk-behind tractor is as follows.

Together with the cutters, aluminum blades are placed in the same plane with the shaft.
The blades must be perpendicular to the movement of the vessel. These look like rectangular plates, half hidden under water. The rest moves freely through the air.
The device is attached to the hull of the craft and allows it to move easily even in shallow waters and bodies of water with rapid currents.

Tips for using an electric screwdriver

volt power supply is assembled, the screwdriver becomes mains-powered. It must be used according to the rules:

every 20 minutes of work, take a break for 3-5 minutes to allow the block element to cool down;
If you operate an external unit, make sure it is clean. It should not be dusty or dirty. This will cause the device to heat up faster and work less efficiently;
the updated tool cannot be used at a height of more than 200 centimeters;
equip the element with a residual current device. If there are problems with the network, the RCD will save the equipment from breakdown;
All wires must be securely soldered.

DIY switching power supply for a screwdriver

A suitable microcircuit is selected for the pulse unit, and assembly is carried out in the following sequence:

Diode bridges and a thermistor are placed at the input. Two capacitors are installed. Drivers are used to synchronize the operation of the gates of field-effect transistors. When installing transistors, the flanges are not short-circuited. They are attached to the radiator using insulating washers and gaskets. Diodes are installed at the output.

Use in the garden

We are part of nature. How harmoniously each of us feels in the garden, dacha or personal plot. An evenly mowed lawn and weeded beds delight our eyes. But it’s very difficult to achieve such a result manually. An aching back and grass-cut fingers can be eliminated from your life if you use ingenuity and, using the most primitive tools, construct a garden trimmer, or a lawn mower, as we are more accustomed to calling this tool.

Making such a trimmer is very easy. To do this you need:

Screwdriver with battery;
Body polishing disc;
Two stationery blades;
Two screws.

Creating a tool literally takes a couple of minutes. Two office blades are screwed onto the body polishing disc. Only they are not screwed tightly, but so that they “dangle” easily. This connection option allows the blades not to break, but to fold when they come into contact with an obstacle. The disk itself with the blades already attached is installed in the screwdriver, naturally with the cutting tool facing down. The tool is ready to use!

This amateur trimmer will allow you to mow grass in hard-to-reach, narrow places, between rows or where there are partitions. Of course, an undoubted “plus” is the saving of time and effort that you spend on weeding by hand. There seem to be only two disadvantages - you still have to bend down and cut the grass in this position, and then collect it manually.

It also has its own specifics. With such a tool you need to “fight” tall grass in a special way. Cut the top first and then the base, as long grass can get tangled at the base of the disc. Then it needs to be removed manually.

Cool ideas and lifehacks for using a screwdriver at home

In addition to the listed mechanisms, a screwdriver can also be used to implement other ideas on the farm. This hand-held power tool will help you automate the opening of an entrance gate, make a winch for a car, or make scissors for cutting metal. If you attach an attachment for cutting tin to it, you can turn an ordinary rubber boat into a motor boat, and modernize the process of drilling holes for ice fishing. In addition, everyone knows that a screwdriver is used as a drive for a mixer, meat grinder or juicer.

After reading the article, the reader gained knowledge about the unconventional use of a screwdriver. Now he can use this hand tool to create carpentry equipment, improve children's vehicles and other useful things in the home.

What can a boat motor be made from?

The motor can be made in various ways, the main thing is to choose a suitable base and additional parts. An engine from a trimmer or walk-behind tractor, as well as a screwdriver, can be used as a base. A boat motor made from a chainsaw has the best characteristics.

From the trimmer

The trimmer boat motor saves fuel and has a transparent tank. The propeller (homemade propeller) is made of duralumin. The propeller blades are bent up to 10 mm, the edges are carefully sharpened. It is put on in place of the trimmer head. To prevent the propeller blades from damaging the boat during operation, use a ring attachment. The motor shaft and propeller are connected by adapters. The starter is removed from the lawnmower. The motor from the trimmer is made according to a drawing prepared in advance.

From a screwdriver

If you use a cordless screwdriver, you will get a good homemade engine. For manufacturing, it is better to choose a device with a voltage of 12 V. The process of making an electric motor for a boat with your own hands using a screwdriver:

The propeller must have a lifting mechanism, so it is attached to the engine transom and secured with frames and plates.
Clamps are equipped with rings. A tube with a shaft is laid through them. The shaft is made of steel wire or rod.
Bearings are pressed inside the tube. They will provide the steel shaft with easy sliding.
To reduce the speed of the electric motor, install a gearbox from an angle grinder. The upper part of the shaft is clamped in the screwdriver chuck.
The propeller is made of stainless steel, the thickness of the sheet is 2.5-3 mm.

From a walk-behind tractor

From a walk-behind tractor starter you can make a motor for an engine. To assemble a four-stroke model, a simple fuel system is used, but the water pump must be of high quality. The sternwood is removed from the old boat engine. The fuel pump is installed above the carburetor so that it does not come into contact with the rocker arm, and secured with clamps. The crankshaft is mounted above the top gear. A water pump is installed under the deadwood. If you install springs, the lower rod will work freely.

You will find many other interesting homemade products from scrap materials here.

Saw from a screwdriver

TOKARKA. The story demonstrates the process of making a compact automatic mechanical saw from a screwdriver. Using this machine you can cut the same materials as a simple hacksaw, but with high precision and much faster. If the workpiece is large enough, while it is being cut, you can do your work without paying any attention to the machine.

Before assembling the sawing machine, the master watched a huge number of videos on the topic on Youtube, but did not find a single assembly video. The entire design is the author’s development, since I have not seen a single mechanical saw with a vertical flywheel, only a lateral one.

Judge for yourself about the dimensions and weight: the device can be carried with one hand. And absolutely everyone who has disassembled a cordless screwdriver at least once in their life will recognize a couple of details. Absolutely every do-it-yourselfer who has some work experience can cope with the manufacture of the device. Compared to a cutting tool such as a grinder, the thing works quietly. Secondly, it does not scatter dust throughout the room, and the cut is quite narrow, which saves material. There are absolutely no problems with cutting tough metals or plastics. Anyone who has worked as an angle grinder will understand perfectly well. The device can be used in field conditions, where there is no power supply, if it is powered from a battery, any suitable one. For example, a car or from a battery for a screwdriver. If you remove the vice from the machine, you can saw through fairly large objects. I think I’ve told you enough about what the thing is for and how to use it. Let's start manufacturing.

This thing is called a “furniture guide”; you can buy it at various furniture hardware stores or construction supermarkets. For further work, it must be carefully disassembled into parts. The middle retractable part rode on balls that were inserted into a plastic separator; they will also be useful to us. Due to the fact that the guide is not new, it was a little rusty and I decided to clean it a little, so that it would be pleasant to work with and would look better. I glued two metal parts together using epoxy resin. All holes through which it could leak were carefully sealed with tape. I put fiberglass fabric inside, although it would have been possible to put regular cotton fabric.

To ensure that the inner and outer steel parts were well centered with each other, I inserted pieces of a plastic separator with balls into the edges and they were precisely aligned. To increase the fluidity of the epoxy resin, I heated it with a hot air gun. This is a DC electric motor, used in cordless screwdrivers. It has an operating voltage of 12 volts and several amperes of current. The shaft rotates at a speed of 550 rpm. It is not fast, but it has a lot of torque. The part is also from a cordless screwdriver, it is called a gearbox. It has two stages of gear shifting, that is, minimum speed and maximum torque are required.

Two jokes - a connecting rod and a couple of needle bearings were purchased in one of the online stores. You can also easily find it in various service centers. This is what a planetary type gearbox looks like from the inside, its second stage looks exactly like this one. The reduction in speed is achieved due to the difference in gear ratio from the gear on the engine shaft to the spindle of the gearbox itself. The cover that covered the first stage of the gearbox was easily removed with a twist and the engine was secured with two M4 screws. And I put everything back in. I decided to conduct a small test of the compatibility of the motor and gearbox. Everything works perfectly.

The saw uses a computer power supply. Now the engine is connected to 5 volts and 14 amps. In order to separate the plastic cap, I unscrewed two self-tapping screws that held the steel washer. The hefty spring is part of the system for separating the spindle from the gearbox. She's not needed. Under the steel ring, on which the spring pressed, there are holes, in which there are a couple of steel balls. The easiest way to stop them from popping out is to pour epoxy resin underneath them. But so that it does not flow too deep and far, slightly frozen. Next from 5 minutes

Using the windshield washer motor

Some owners who decide to make their own electric motor for a boat use various 12V engines that are used on board the car.

Such engines are perfect for such functions, if only because they are designed to run on a car battery. Despite this, they require some improvement.

Boat owners are constantly experimenting and finding amazing solutions. The high cost of industrial designs forces them to do this. As a result, the idea of installing a lawn mower motor on a boat was born. These are engines with a power of about 6 hp, which are designed for long-term operation under load in various conditions. Such an engine can be adapted to a boat if you use various spare parts intended for repairing Soviet boat engines.

Motor from the Ural-2 chainsaw

Some craftsmen easily adapted motors from Soviet chainsaws as motors for boats. At one time, a huge number of chainsaws were produced, the quality of which needs to be discussed separately. Despite this, some motors installed on boats still serve today. The main thing is to calculate everything correctly.

Engraver

In order to make an engraver (drill) from a screwdriver without a battery or with a battery, you can use a special adapter, which is sold in a hardware store. You will also need a bit, the diameter of which must match the hole in the adapter.

To make an engraver from an old screwdriver with a working motor you will need:

disassemble the screwdriver body and remove all the insides from it.
remove the gearbox from the motor so as not to damage the shaft;
attach the bit attachment to the shaft.

To protect your hand from the current that can “hit” the motor, you can wrap it with electrical tape or make a protective casing made of rubber (silicone).

From an old tape recorder

Another basis for a mini-drill can be the electric motor of a well-worn player or tape recorder that rotates a CD disc. The standard motor of such devices runs on 6V voltage, so you may need to additionally purchase a portable power supply or build a mount for a battery or battery.

Using two soldered wires, the power unit (via a switch button or without it) is attached to the motor and fixed with tape or glue in a homemade tube-shaped housing. After this, the same collet chuck is attached to the shaft, which holds the drill.

Important! To avoid “figure eights” and vibration of the drill, the diameter of the collet hole must correspond as closely as possible to the size of the engine shaft, usually 1.5 - 2.3 mm, and sit tightly on it.

Making a garden shredder

A garden shredder for grass and thin twigs (less than 1 cm thick) can be made on the basis of a corded drill-driver.

Create an aggregate like this:

choose a suitable container, for example, zinc boiler;
a hole is drilled in the center of the bottom for the shaft on which a knife or several blades will be fixed;
make a wooden or metal frame to install the container or place it on the edge of the table;
a drill-driver is attached to the frame or bottom of the boiler, which is equipped with knives;
install an on/off button;
make a slot in the side of the container - cut out a rectangle 10 by 20 cm in front of the bottom;
A sleeve is made from tin for disposing of crushed plants;
attach it to the container;
check the functionality of the unit.

The easiest way to make knives is from hacksaw blades

. They need to be installed with the point down. In this case, you can make several versions of blades for different grasses. If you make an attachment in the form of knives for a drill-driver, then you can simply chop the grass in a bucket or other suitable container.

Greetings. Today I want to tell you how I made a drill with my own hands for “three kopecks”, and at the same time it was effective and practical. I hope my solutions will be useful to someone else.

As a former builder and decorator, I have a lot of different power tools at home. However, when you do all sorts of desktop handmade things, sooner or later you realize that it’s time to buy something like a Dremel. And since I’ve already set out on the path of home-making, I decided to make the stray stuff myself.

In general, I purchased a cordless Dremel 1100-25 Stylus Hobby as a donor - without a charging station, without a cartridge, with half-dead batteries. But I liked it so much that it became a pity to ruin it, so I want to restore it (I’ll report on that later).

To solve the problem, the following was ordered from Ali: • a motor, • a cartridge for the shaft with a set of collets, • several connectors. The products arrived in Ukraine in 20 days with free delivery and were packaged in polyethylene foam. Everything else was scraped together.

I caught my eye on the 12 volt motor "high quality DC3-12V large torque motor super model high speed motor". Now this model is not available from the seller, but at the time of purchase the product cost me 197 rubles and kopecks.

A similar unit is installed on the original Dremel, only it is about a centimeter longer (it has an impeller installed in the body for cooling). In appearance, the motor is nice and of high quality. It is compact in size, here are its actual dimensions: length - about 40 mm, diameter - 27.4 mm, shaft diameter - 2.3 mm, length of the open part of the shaft - almost 13 mm.

Here are the performance specifications from the product page: • Voltage range: 3.0-12V • Rated voltage: 9V • No-load speed: 20160 • No-load current: 680mA • Maximum current: 3.8A • Rated torque: g.

cm • Rated power: 20 W • Starting torque: 1000 g. For cm Looking ahead, I will say that the motor turned out to be really playful and powerful.

I ordered a collet chuck from the same seller, fortunately, at that time he also had a quite humane price tag - 194 rubles (the link to the product now shows page 404).

For some reason, the cartridge did not indicate what shaft diameter it was suitable for, but after reading the comments, I realized that the product would fit well on a motor. The set arrived in a neat box and a spare parts bag, which, in addition to the cartridge, contained 5 collets with a working diameter of 0.5 to 3 mm, as well as an hex key.

Everything is of very high quality, the cartridge is attached with two barrels. The cartridge sat very tightly on the shaft, without any doping or play. Tests have shown that there are no beats at all, literally at all. By the way, the shaft is completely inserted into the chuck, so the lateral load is minimal. The cartridge also qualitatively clamped two collets from another manufacturer.

Since the voltage range is quite wide, I tried several options available. The power supply from the television antenna (12 volts, 100 mA) and from the telephone (5 volts, 800 mA) predictably did not start the motor. Also, the 9-volt transformer TP-30-2 from the VEGA radio (0.7 A) did not work.

But the computer power supply with its 16-20 amperes turns the motor with a bang. Lines tested at 3.3 volts, as well as 5 and 12 volts. Using these three outputs as needed, I resolved the issue regarding speed control, although I was thinking about more elegant solutions using special boards.

Also (for a crossword puzzle) the engine was powered by one 18650 battery and two - the flight is normal, you can safely make an autonomous model if you choose a suitable housing. My casing was only 12-15 mm too short to fit the battery inside without major modifications.

I was considering the case of a Rickson roll-on deodorant, but my neighbor promptly fitted a box that was ideal in size, which is a device for producing soap bubbles. The engine enters it with gaps, but closer to the bottom it literally becomes a surprise.

That’s why the motor was placed that way, and the “stiffening ribs” turned out to be very convenient for a reliable grip. I cut the hole for the shaft with a margin to get some ventilation from the front part. In addition, in order to somehow remove the heat, I used a six-piece drill to make holes in the body - a lot near the body of the motor and a few above.

I found a button in the garage and deliberately used a large one to make it more reliable and not miss the mark. I placed it at the end so it wouldn’t get in the way while working. Based on the 12-volt Proxxon Micromot 50/EF drill, I came up with the idea of installing a “spiral” power cable, which is less in the way and is more flexible.

I found one like this on the farm - from an old Philips electric razor. I didn’t make it removable, I soldered it directly to the engine, although for greater ergonomics it was possible to move the button a little to the side and attach a “female” type socket to the end. I chose the connectors based on reliability, but they also fit well into the green color ensemble. I recommend.

They are neat and practical, the contact is tight.

I bought it in real life, but there are also such products on Ali, they are inexpensive - as an option: aliexpress.com/item/10-Pcs-CCTV-Cameras-2-1mm-x-5-5mm-Male-DC-Power-Plug- Adapter-DC-Power/32598414355.html (1.7 USD for 10 pieces).

The entire assembly consisted of unsoldering the button, connecting the cord and installing the connectors. And from the inside, the motor in the housing was slightly fixed with hot-melt adhesive nozzles so that when drilling it would not go inside.

For hanging storage (it has now taken pride of place next to my work desk), I attached a bracket made of 2.5 mm hard copper wire to the Dremel through the ventilation holes, which, if necessary, can be easily detached from the case. The car turned out to be very compact, but powerful.

I tried to process a piece of thermoplastic polypropylene pipe. The machine performed excellently on this viscous material. Manipulations with metal and wood are no problem at all.

1. It took about an hour and a half to create the drill, including “design”, smoking breaks and photographing. 2. Only 400 Russian rubles were spent on the creation of the instrument itself.

A used computer power supply was purchased on the market of the city of Slavyansk, Donetsk region for 150 Ukrainian hryvnia; I will also use it to power LED strips and dead cordless screwdrivers. Plus I used a little small things. 3.

Torque and rotation speed (adjustable) are more than enough. 4. Ideal ergonomics “to suit you”. 5. Pleasure from the process of creation.

And who cares where the hands come from if they are golden!

Do-it-yourself accessories for a hand drill, drawings. A simple homemade drill (from junk)

A homemade drill will not cost much and will not cause any problems during manufacture. It will be useful in many situations, including when performing such technological operations as:

drilling;
drilling holes;
processing of grooves and recesses of various configurations;
engraving;
polishing;
cutting of plastic products;
cutting non-ferrous sheet metal (aluminum, brass, bronze, etc.) up to 1.5 mm thick.

The drill, made according to the instructions below, is distinguished by its compact dimensions, light weight and ease of use.

Such a device, made by hand at home, is equally successfully used to perform small and quite serious work with products made of various materials - metal, wood, plastic, bone, etc.

Such a drill is very useful in jewelry making, when repairing small items for various purposes, manufacturing and repairing electrical devices, and in many other situations.

What you will need

How to make a drill with your own hands? You can use various options for its design. As the main working element of such a device, it is very convenient to use attachments that were supplied with old-style dental drills.

Such an attachment, as a rule, is initially mounted on a flexible shaft, from which it must be removed by unscrewing its spring. From the bottom of the dismantled drill attachment, you need to cut off a not too wide ring, which will act as a nut used to fix the entire device on the plate.

In addition, by cutting off such a ring, you will free the end of the shaft on which the gear will be mounted.

On the engraver attachments, made by yourself in the proposed design, you can install various types of replaceable tool holders. Such holders, in particular, can be:

straight;
with a lateral arrangement of the tool;
with a curved working head.

More universal are direct type holders, which are used in 90% of cases. In situations where the location of the element being processed does not allow the use of straight holders, they turn to curved type nozzles with a side-mounted tool.

When choosing working attachments from an old drill to equip your homemade engraver, keep in mind that they can only be used in conjunction with a tool whose shank diameter is 2.35 mm.

At the same time, tools intended for installation in straight-type holders are distinguished by an elongated shank.

The shanks of burs installed in corner holders are shorter and have a special groove (slot).

Using homemade attachments for an engraver from an old drill has a number of advantages. The main one is that you can purchase such a drill for very little money, since such devices are practically no longer used in modern dentistry. Finding and buying tools to equip such attachments is also not a problem.

Assembling a homemade device

In order to be able to use an attachment from an old drill to perform minor work on items made of metal, plastic, wood and bone, it is necessary to make a device with which such an attachment will be driven by a small electric motor of the required power. As a drive motor for a homemade drill, you can use a small, but resourceful and powerful motor from an ordinary hair dryer or an old VCR.

What are homemade boat motors made from?

Many fishermen have faulty electrical or gas equipment in their storage room or garage. If the motor in it is working properly, then such a device can be modified to fit an existing boat. In some cases, it is even cheaper to purchase a new screwdriver or brush cutter and modify the device than to buy a boat motor. It is the financial issue that pushes numerous “left-handed” and “home-made” people towards unique developments.

To make a homemade electric boat motor, you will need a cordless drill or screwdriver. In this case, the fisherman will have to solve the following problems.
Unfortunately, the capacity of the standard battery will not be enough for carefree sailing, so you will have to take a 12V car battery on board. Accordingly, the device must also operate at the same voltage. As for power, an electrical device that produces more than 300 W can handle a light rubber boat.
The rotation speed of the screwdriver is quite high, so it is necessary to install a reduction gear.
You also need to purchase or make your own drive shaft and propeller.

A homemade electric boat motor will operate silently, which is very important for good fishing. In addition, replacing a failed electric motor will be cheaper than repairing a boat engine

Gasoline engines made for a boat with your own hands can significantly increase the fishing area. These can be power units from chainsaws, lawn mowers, walk-behind tractors, etc. The choice of installation depends on the size and design of the vessel, as well as which of the devices is available.
Trimmers require the least modifications. They look like they were made to be installed on a fishing boat. It is enough just to install a propeller instead of a reel with fishing line and the boat motor from the trimmer can be tested on a nearby body of water.
Engines from a chainsaw, motorcycle or walk-behind tractor will require more intervention by skilled hands. Requires a bevel gear from an angle grinder, a shaft and a propeller.

All homemade boat motors require a special device for attaching to the side of the boat. It's one thing when the boat has a transom to which you need to attach the engine. It is somewhat more difficult to secure the power unit on a regular elastic band with inflatable sides around the perimeter.

Homemade charging devices

It’s quite simple to make a charger for a 12-volt screwdriver yourself, by analogy with the one used in the Interskol charger. To do this, you will need to take advantage of the ability of the thermal relay to break the contact when a certain temperature is reached.

In the circuit, R1 and VD2 represent a sensor for the flow of charge current, R1 is designed to protect the diode VD2. When voltage is applied, transistor VT1 opens, current passes through it and LED LH1 begins to glow. The voltage drops across the chain R1, D1 and is applied to the battery. The charging current passes through the thermal relay. As soon as the temperature of the battery to which the thermal relay is connected exceeds the permissible value, it is triggered. The relay contacts switch and the charging current begins to flow through resistance R4, the LED LH2 lights up, indicating the end of the charge.

Circuit with two transistors

Another simple device can be made using available elements. This circuit operates on two transistors KT829 and KT361.

The amount of charge current is controlled by the KT361 transistor to the collector to which the LED is connected. This transistor also controls the state of the KT829 component. As soon as the battery capacity begins to increase, the charging current decreases and the LED gradually goes out accordingly. Resistance R1 sets the maximum current.

The moment the battery is fully charged is determined by the required voltage on it. The required value is set with a 10 kOhm variable resistor. To check it, you will need to place a voltmeter on the battery connection terminals, without connecting the battery itself. Any rectifier unit designed for a current of at least one ampere is used as a constant voltage source.

Using a custom chip

Manufacturers of screwdrivers are trying to reduce prices for their products, often this is achieved by simplifying the charger circuit. But such actions lead to rapid failure of the battery itself. By using a universal chip designed specifically for the MAXIM MAX713 charger, you can achieve good charging performance. This is what the charger circuit for an 18-volt screwdriver looks like:

The MAX713 chip allows you to charge nickel-cadmium and nickel-metal hydride batteries in fast charge mode, with a current of up to 4 C. It can monitor battery parameters and, if necessary, reduce the current automatically. Once charging is complete, the IC-based circuit draws virtually no power from the battery. It can interrupt its operation due to time or when the temperature sensor is triggered.

HL1 is used to indicate power, and HL2 is used to display fast charge. The setup of the circuit is as follows. To begin with, the charging current is selected, usually its value is equal to 0.5 C, where C is the battery capacity in ampere hours. The PGM1 pin is connected to the positive supply voltage (+U). The power of the output transistor is calculated using the formula P=(Uin - Ubat)*Icharge, where:

Uin – highest voltage at the input;
Ubat – battery voltage;
Icharge – charging current.

Resistance R1 and R6 is calculated using the formulas: R1=(Uin-5)/5, R6=0.25/Icharge. The choice of time after which the charging current turns off is determined by connecting the PGM2 and PGM3 contacts to different terminals. So, for 22 minutes PGM2 is left unconnected, and PGM3 is connected to +U, for 90 minutes PGM3 is switched to the 16th leg of the REF chip. When it is necessary to increase the charging time to 180 minutes, PGM3 is short-circuited with the 12th leg of the MAX713. The longest time of 264 minutes is achieved by connecting PGM2 to the second leg, and PGM3 to the 12th leg of the microcircuit.

Lathe

A lathe can be obtained if the screwdriver is fixed in a wooden stand and placed on a horizontal surface.

A hand generator is a device similar to a wind generator. The procedure for its manufacture is identical to the assembly of a wind generator. At the last stage of work, instead of an attachment with blades, a handle is attached to the screwdriver.

Making an electric bike is easy:

Remove the motor from the screwdriver.
By connecting it to a bicycle sprocket.
Install the mechanism into the bicycle.

Such a device for a child can be made from plastic pipes, fastened together with plastic ties, and a motor from a screwdriver can be used as a motor for a catamaran.

This device is quite easy to assemble. To transform an old tool into a new one, you need to attach a metal cutting disk to a screwdriver instead of a drill.

Instead of the motor, you need to install LEDs, observing the current strength, the flashlight is ready.

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.

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

Modernization of children's vehicles

And of course, all the best goes to the children. Using a screwdriver, you can modernize many children's vehicles. For example, convert a children's pedal car into an electric car.

Electric car

To make a car with electric drive you will need:

Frame made of steel profile pipe. You can make it yourself.
The wheels can be used from a rubber garden cart.
You can take the body from an old pedal car or come up with some creative solution. For example, soldering from plastic pipes.
As an electric drive, it is necessary to use two motors from screwdrivers and a gearbox from the same power tool. Separate housings are made for them, in which the output shaft is mounted on 201 bearings.
Battery. You can use a regular automobile 6ST60.

After all the components are prepared, all that remains is to assemble the electric car. This process is simple and can be done by every man who has even a superficial understanding of plumbing.

Electric scooter and electric bicycle

Another use of a screwdriver in creating vehicles is an electric scooter or electric bicycle. The principle of this modernization is based on installing a chain drive between the wheel sprocket and the electric motor sprocket with a screwdriver gearbox. This device is powered by a hand tool battery. This solution does not require large expenses. As a result of the improvement, a vehicle with a speed of 5 to 15 km/h is obtained.

Electric snowmobile

Using a screwdriver you can make not only a vehicle on wheels, but also a real snowmobile. To do this, you need to use an electric car, having carried out a number of appropriate upgrades. It is necessary to improve the electric vehicle frame to install a drive wheel on it. Instead of driven wheels, you need to install skis, and replace the plastic steering wheel of the car with a metal bicycle handlebar. The drive wheel is driven through a chain transmission from a screwdriver.

Assembling such a wonderful technology will not take much time, and most importantly, money. All costs will be paid off by the joy of the child, for whom an electric vehicle will be a real gift.
