What can be made from an old screwdriver: 19 cool ideas

To make a grinder from a drill, you first need to decide on the power of the tool, that is, figure out what kind of metal you are going to cut. Of course, this option is far from the best for regular use, but if you need to go to any site to perform small work, then such a universal tool can easily fit in a bag or backpack. Based on this, we can come to the conclusion: it is possible to make an angle grinder out of a drill, but only for use in special cases.

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:

1. Frame made of steel profile pipe. You can make it yourself.
2. The wheels can be used from a rubber garden cart.
3. You can take the body from an old pedal car or come up with some creative solution. For example, soldering from plastic pipes.
4. 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.
5. 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.

A device such as a small grinder is needed when an engraver deals with small parts, for example, in the production of souvenirs. Of course, it will be quite difficult to work with an angle grinder by hand, so everything needs to be marked out first; in the future we will no longer have problems with cutting, having such a stand for an angle grinder. A grinder is a tool that can also be used as a router.

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.

Electric car

The idea of ​​modernizing a children's vehicle - a pedal car - can also be brought to life. The result should be a real electric car. True, the implementation of this idea will require some plumbing skills.

To implement the idea, you will need to prepare the following spare parts.

• A steel profile pipe for making a frame, which can be easily made independently.
• Wheels with rubber tires. The best way to do this is to disassemble the old garden cart.
• For the body, you will either need the body of a children's car with a pedal drive, or you will have to make it yourself from scrap materials (plastic or metal-plastic water pipes will do).
• The electric drives should be units from two disassembled screwdrivers: motors and gearboxes will be used from them. They are placed in specially made casings.
• A bearing is installed to support the output shaft.
• A car model is recommended as a battery.

A screwdriver can also help with such improvements to a children's vehicle, such as making a small snowmobile from an electric car.

They use a newly built electric car for this purpose, only slightly modernizing it.

• The frame will be improved to install a drive wheel, which will be the main engine of the device.
• Skis are installed instead of wheels, and the wheels are replaced with a metal handlebar from a children's bicycle.
• The chain transmission will perform the drive functions.
• Such modernization will save both time and money, and the children’s joy will be genuine.

In addition, the process can be recorded using drawings, and the reverse transformation into an electric car will be more than possible with the onset of the warm season.

Carpentry workshop equipment

A few more interesting suggestions on how to make equipment for home carpentry using a regular screwdriver.

Wood lathe

When making wood products, it is difficult to do without a lathe. You can build it yourself. A flat wooden workbench is ideal for the bed. A screwdriver can be used as a headstock and rotation drive. You need to place the tool in a wooden bed made from a block in the shape of a screwdriver and secure it with a clamp. The block can be secured with a clamp, and if the machine is constantly used, screwed with self-tapping screws. A tooth mandrel must be inserted into the chuck. The tailstock is made of two bars with an adjusting screw, which is sharpened to a cone. It is installed opposite the fixed screwdriver so that the axis of the tool coincides with the axis of the tailstock adjusting screw. The back support structure is secured with a clamp. If you plan to process large parts, then the fastening should be more reliable. The tool rest can also be made from a block, securing it to the workbench with a clamp. A primitive lathe for the home workshop is ready.

Bench Drilling Machine

Another equally important piece of equipment is a drill. It can also be made from a screwdriver. To do this you will need a used screwdriver. From it you need to take a motor with a gearbox and a cartridge. Now you need to make two clamps from textolite, which will perform the function of fixing the drilling head of the machine. To achieve maximum alignment of all holes on the clamps, it is better to process them together, in one installation. Then you will be able to avoid distortions.

Bushings with internal threads are used as limiting posts. They must be the same size, corresponding to the distance between the clamps. After this, another clamp is made from textolite and two bosses from caprolon. They are drilled off-center, resulting in two eccentric bushings. The clamp is installed on the rod and the backlash is selected using eccentrics. After this, install a wooden lever on a spring so that the drilling head returns to its original position. To supply power, you must use a transformer with a power of more than 150 watts and an output voltage similar to the screwdriver you are using. After this, you need to install a diode bridge and a capacitor, and install the drilling head on the frame.

Manual router from a screwdriver: step-by-step instructions

It can be converted into a hand router. To do this, you do not need to purchase expensive materials. Everything you need can be found in the workshop or garage, practically under your feet. To make a manual router from a screwdriver, you will need pieces of thick plywood or chipboard, a clamp for attaching the tool, fasteners in the form of bolts and self-tapping screws, plumbing tools and a feather drill for wood. In the latter case, you can use a drill bit.

Assembling a homemade router is quite easy. To do this you need:

• From pieces of the selected material, cut out a base, a vertical stand on which a screwdriver will be attached using a clamp, a stop and a gusset to impart rigidity to the structure. The dimensions of the parts are chosen arbitrarily, in relation to the dimensions of the power tool.
• Using a pen drill, drill a Ø 40 mm hole in the base for free access of the cutting tool to the processing area.
• Make a clamp according to the diameter of the hand tool.
• Using a clamp, secure the screwdriver to a vertical stand so that its chuck is a few millimeters from the base.
• Install the stiffener.
• Secure the screwdriver with the stop on the vertical stand.
• Install the cutter into the tool chuck.

The screwdriver cutter is ready for use. Such a machine cannot become a full-fledged replacement for a manual milling cutter due to its low power and low spindle speed, but it will solve the problem of milling small parts in a home workshop.

Circular Saw

In addition, for your carpentry workshop you can make a circular saw from a screwdriver. To do this, you need to make a working surface using a sheet of chipboard or thick plywood. You need to make a cut in the tabletop to allow the circular saw to exit. The screwdriver must be securely fastened to the underside of the work surface using metal or wooden clamps. In the same way it is necessary to mount the shaft

It is important that the saw blade extends above the working surface of the table by no more than a third of its diameter

Making a cutting machine with your own hands

Preparatory stage

Work on a cutting machine begins with design. It is impossible to give the exact dimensions of the device, since the design depends on the model and size of the specific angle grinder. Nevertheless, from the presented drawings you can get an idea of ​​the dimensions and structure of the equipment.

The design sketch begins with a drawing of the body. You may not need a frame, but a separate platform that can be attached to a bench. In any case, determine the dimensions of the device and the location of the main components on the body. Next, the angle grinder and the center distances of the mounting holes on the gearbox housing are measured. Based on these indicators, a drawing is drawn up for attaching the angle grinder to the pendulum. After this, the rotary unit itself is designed. The shorter the distance from the hinge joint to the cutting wheel, the stiffer and more accurate the machine will be.

In other words, the length of the pendulum should be as short as possible.

At the last stage of design, they calculate how much and what material will be needed.

Drawing of a frame-type cutting machine. Frame dimensions are selected based on the size of the tool used

Drawing of a pendulum type cutting machine. The dimensions of the base are indicated on the left. On the right are the design features of the pendulum.

Step-by-step instruction

1. In accordance with the drawing, blanks of the future machine are cut. For the frame and pendulum, profile pipes are used, and for the cantilever mounting, a metal profile, a metal tire and a steel rod are used. If the design provides for a load-bearing platform, then sheet steel 4–5 mm thick is cut to size.
2. A transverse axis (shaft) is welded to the pendulum arm, which is a section of a profile pipe, for an articulated connection. In this case, it is important to ensure that the shaft is attached to the pendulum perpendicularly. After cutting the material, a shaft is welded to the pendulum arm
3. A U-shaped bracket is bent from a steel tire, holes are drilled in its sides for bolts, with which the gearbox housing of the angle grinder is secured. To attach to the threaded holes on the angle grinder gearbox housing you will need a U-shaped bracket
4. A U-shaped clamp (ladder) that goes around the angle grinder and a clamping bar for fixing the tool body to the pendulum are made from a steel bar. The latter is a metal plate 15–20 mm longer than the width of the clamp. The threaded ends of the stepladder fit freely into the holes at the edges of the pressure plate, and fixation is carried out with nuts with suitable threads.
5. Trying on the U-shaped bracket and clamp to the angle grinder, mount these parts onto the console using a welding or threaded connection. This is what the console for attaching the angle grinder to the pendulum arm looks like, complete with a U-shaped bracket and clamp
6. The bearings that will ensure the rotation of the pendulum are pressed into the supports. As the latter, you can use either ready-made factory bearing units or sections of steel pipe (15–20 mm) with a diameter equal to the outer race of the bearing.
7. Bearing units are pressed onto the shaft from both sides. It is important that the connection is tight - this will eliminate unwanted longitudinal and transverse displacements. If the resulting connection is weakened for some reason, you can use a proven method - tin the axle with a soldering iron, applying a thin layer of tin to its surface (you will need soldering acid as a flux).
8. At a distance of 50–60 mm from the edge of the platform, the pendulum assembly with support units is welded. At the same time, it is important not to overheat the bearings, so these parts are wrapped in a wet rag or constantly watered with water to cool. The pendulum arm assembly with bearing units is welded to the platform at a distance of 50–60 mm from the edge
9. A console with an installed clamp and a U-shaped angle grinder mount is welded onto the pendulum arm. The position of the grinder is chosen based on personal preferences. There are different opinions on how to attach the angle grinder (“from yourself” or “towards you”).
   Professional mechanics work with the tool, orienting the sheaf of sparks towards themselves, arguing that if the grinder falls out of their hands for any reason, the tool will fly off in the opposite direction. Hobbyists most often work with medium or small sanders, so they prefer to have the disk rotate “pull”, as this allows for control of the cut and prevents damage to clothing. When securing the tool, do not forget to place the protective casing correctly - it should protect the worker in the event of a disk rupture.
10. An angle grinder is attached to the assembled machine. Based on the weight of the tool, select and install the return spring. To do this, hinges are welded to the frame and pendulum or holes with a diameter of up to 5 mm are drilled. In order not to damage the plastic body of the angle grinder, strips of rubber are laid between it and the brackets
11. Perform a test run of the grinder. First, check the operation of the machine in idle mode. At the same time, pay attention to vibrations and play in the working parts of the equipment, which are eliminated if necessary.
12. Using a cutting wheel of maximum thickness, a groove is cut in the machine platform for the cutting disc. If necessary, the grinder is removed and the slot is expanded to the desired size. This is what an improved stop with a clamping device looks like

At the last stage, workpiece stops are attached to the platform. Most often, two strips are provided (for cutting at an angle of 45 and 90 degrees), fixing them with a welded or threaded connection.

Often, devices for holding the workpiece are equipped with a measuring tool. By attaching a metal ruler to the stop bar with a reference point from the grinder disk, you can quickly and accurately cut the part to the required length. Also, if desired, you can install protractors, vices and clamps of various designs. Such additional details allow you to make, for example, a full cut or groove in the workpiece at any angle, free your hands, and so on.

Don’t forget to paint the fixture after all finishing work has been completed. Even a thin layer of enamel will protect the equipment from rust and make its appearance more aesthetically pleasing.

boat motor

How nice it is to take a boat ride in warm summer weather. The only problem is that I don’t want to pick up the oars. Ingenuity comes to the rescue.

What if you adapt a motor from a screwdriver to a boat using available tools?

It’s easier to use the following materials for this “idea”:

1. Screw (rabbit):
2. Long metal pin;
3. Battery powered screwdriver.

The essence of the idea is as follows. A hole with a diameter equal to a metal pin is drilled in the propeller (in this situation, the propeller). The screw is installed on the stud and securely fastened. The long pin itself is inserted into a screwdriver, which turns the pin together with the screw. The boat engine is ready!

All that remains is to come up with some kind of metal structure that will allow you to securely attach the screwdriver to the boat itself. But this is too simple a task to discuss. And every amateur will be able to show his inventive abilities in this matter.

We lower the screw on the hairpin into the water and turn on the screwdriver. All that remains is to slowly swim and enjoy the beauties of nature that you see around. There is only one thing - realistically evaluate the capabilities of the batteries and “don’t swim behind the buoys.”

Trimmer belt

For more comfortable work with the trimmer, if you intend to process a large area covered with grass, it is advisable to use a special belt. This device relieves fatigue from the hands and back of the mower operator and greatly facilitates the process when compared with the same work, but without a belt.

There are shoulder straps and backpack straps. The shoulder strap is the simplest device and consists of a loop with two or one latch (carabiner), with which it is attached to the mowing unit. A plastic plate is usually attached to the second carabiner, protecting the operator's side from pressure from the trimmer bar.

The shoulder strap is usually used with lightweight trimmers weighing 3-4 kg. For heavier units it is more convenient to use a backpack belt.

A trimmer belt can be easily ordered online or purchased at a specialized store that sells these devices and their accessories.

If you want to make it yourself, then any housewife, looking at this device, can easily sew it from improvised materials (old belts and belts). You may have to buy buckles and carabiners. But we still recommend buying a ready-made backpack suspension and not wasting time and money on making a device of worse quality than the ready-made one.

Preparing the electric drive for a bicycle

First of all, you need to remove the clamping chuck from the remains of the screwdriver. This is extremely simple to do, and therefore there is no point in describing this action. Then a thrust nut is screwed onto the shaft. It serves to ensure that the installed sprocket does not touch the body. By the way, it makes sense to immediately change the position of the power regulator to “drill”.

PHOTO: YouTube.com An internal thrust nut is installed on the shaft

Next, you need to put the sprocket on the engine drive shaft and secure it with a second nut, which can be removed from the chuck. But if everything is left in this form, the fixing nut will loosen when moving. Therefore, first it is thoroughly pulled, after which a screw with a reverse thread is screwed into the internal thread of the shaft. This system will ensure that the sprocket is fully secured and eliminates the risk of the outer nut coming loose while driving.

PHOTO: YouTube.com The second nut is fixed with a screw with a reverse thread for reliability

Fastening the engine to the bracket

Now it remains to understand how the electric motor will be attached to the bracket that will be installed on the bicycle. Everything here is extremely simple. For this, a regular plumbing clamp designed for sewer plastic pipes with a diameter of 50 mm will be used. The pin with the anchor should be unscrewed from it, and the clamp itself should be placed on the motor housing. The photo example below shows how this is done.

PHOTO: YouTube.com A plumbing clamp is perfect for attaching to a bracket

At this point, the work on preparing the electric motor is completed, you can proceed to the manufacture of the bracket.

Main components of a garden shredder

To independently assemble a grass and branch chopper (shredder) at home, you must first understand the structure of the mechanism, as well as the principle of its operation. This will help you assemble the equipment correctly and, if necessary, make changes to its design.

A homemade unit, designed for grinding mown grass and sawn branches up to several centimeters thick, has the following main structural components:

• engine;
• knives mounted on the working shaft;
• frame (usually metal);
• protective casing;
• a box designed to receive cut vegetation;
• starting system.

The equipment itself can be made stationary or mobile. To create the latter option, you will additionally need wheels, as well as a handle. To make the frame, use metal corners or ready-made frames from workbenches. Boxes for processed vegetation are made from plastic buckets, tin, and bags. The protective casing around the knives should be thick and durable enough so as not to quickly wear out from the impact of grinding vegetation.

When processing plant debris, crushed pieces may fly out of the opening through which it is fed. Therefore, the neck is covered with a lid or simply with a cloth, for example, a bag.

The operation of the chopper is that rotation from the motor shaft is transmitted directly to the knives or through a chain/belt drive. The vegetation chopped by the blades enters the box. In this case, the final product is immediately ready for use.

According to the principle of operation, some homemade shredders are comparable to a meat grinder (they draw in and then grind organic matter), while others are comparable to a coffee grinder.

Epilogue

This is how you can assemble an electric bicycle without any expense. Of course, additional work is needed here, but the foundation is already there. It's quite fun to see people's reactions when they see such an interesting vehicle. Of course, it’s unclear what’s moving along the road. In fact, if you work on the bike for a couple more days, it will not be inferior to expensive factory products in almost any way. Considering that all the work is done “on the knee” in one day, without financial investments, we can say with confidence that the idea is very good.

We hope that the material presented today will be useful to the dear reader. If you still have questions about what you read, you can ask them in the discussions below. The HouseChief editors will be happy to answer each of them as quickly as possible. There you can comment on the article and express your opinion about the rework. Tips for improvement, as well as pointing out the wizard's mistakes, are welcome. And we have one request. Please don't forget to rate what you read.

Every opinion, both positive and negative, is very important to us. Happy cycling!

Characteristics of electrical equipment

When you start making an electric car with your own hands, this is the point you need to pay special attention to. The fact is that the reliability of the machine and the safety of your child depend on the characteristics of this equipment.

Of course, first of all you should make sure that all contacts are reliably insulated.

Many people believe that the braking system can be made by simply placing an “On/Off” button on the panel. from a screwdriver. Of course, in this case, operating the machine becomes as simple as possible. Just keep in mind that sudden braking can lead to very unpleasant consequences. So the brakes need to be done through a resistor.

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:

1. Screwdriver with battery;
2. Body polishing disc;
3. Two stationery blades;
4. 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.

First option - Using a drill + (Video)

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

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

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

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

Assembling an electric bicycle from an old screwdriver

When all the parts are prepared, you can proceed directly to assembly. But first you need to prepare the bike itself.

Some details are removed from it, namely:

• pedals (they are no longer needed);
• trunk (will be moved forward);
• chain (you still have to work with it).

Now the bike is ready, and you can get started. The bracket is fastened to the “ears” on which the trunk was fixed. In this case, the foot should rest against the frame.

PHOTO: YouTube.com The bracket is already in place, all that remains is to install the engine

Installing the electric motor on the bracket

Everything is simple here. Through the slot, using a suitable bolt, the electric motor is mounted on the platform. There is no need to tighten the connection at this stage.

PHOTO: YouTube.comThe engine is in place, but the connection has not been pulled yet

Adjusting the chain length

The chain removed from the bicycle will have to be adjusted to length by removing excess links. Ultimately, it should sag a little to allow for modifications.

PHOTO: YouTube.com The chain needs to be adjusted to length by removing excess links

Adjusting chain tension

The bracket is movable, so you need to lift it up, move the stop tab and fix all the connections in the desired position.

PHOTO: YouTube.com The chain is tensioned, the connections are fixed, now comes the fun part

Installation of electrical equipment

The electric motor activation button must be installed on the steering wheel, which means you will have to extend the wires. To do this, you can use a regular soldering iron. The cores themselves should be corrugated for protection.

PHOTO: YouTube.com The wires need to be extended to be able to install the button on the bicycle handlebars

PHOTO: YouTube.com The button is conveniently fixed on the steering wheel

At the same time, a power wire is also output, which will go to the battery.

Battery installation and connection

It's time to install the trunk. It is necessary to accommodate the battery. It is easy to install it above the front wheel; just screw in the 4 fixing screws. Almost all bicycles provide such reinstallation.

PHOTO: YouTube.com The trunk, removed from the rear, is installed above the front wheel

A car battery is placed on the installed trunk, to which the wires from the button are connected. The battery itself is securely fixed with brackets so that it does not slip while driving.

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, instead of a handle, you can insert an attachment with blades

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

Screwdriver as a generator

A screwdriver can be used as a generator. It's very easy to do. You need to remove the battery, attach wires to the terminals using alligator clips and connect them to the consumer. Be sure to first check the polarity with a multimeter. You need to insert and clamp a hex key into the chuck to assemble the furniture. By rotating the spindle, a current will be generated that will be supplied to the consumer. However, it is worth noting that the voltage generated by this electric machine is only enough to charge a mobile phone or operate a small LED lamp.

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).

Bracket for attaching an electric motor to a bicycle

To make this part you will need a metal plate and a section of channel. It is not difficult to find such parts in a garage or at any metal receiving site.

PHOTO: YouTube.com These are the steel parts needed to make the bracket

These parts need to be welded together, and then a slot is made in the plate using a grinder. It will serve to secure the electric motor with a bolt. A regular hole will not work here; the mount must be movable so that the alignment of the drive and driven sprockets can be adjusted. If you don’t set it, the chain will fly off without allowing you to travel even a meter.

Pressure foot, and what is it for?

Making a bracket support tab is a purely individual process for each model and brand of bicycle. A photographic example will show a similar detail so that the reader can understand what it looks like. And it will serve to adjust the chain tension. The thrust tab is attached to the bolt and nut, the connection remains movable until fully tightened.

Possible variations of a homemade trimmer

In the factory trimmer, 1.5 mm fishing line is used as the cutting element. Can it be used in a homemade device? Yes, but to install it you will need additional fastening

In addition, it is worth taking into account that the fishing line will constantly need to be lengthened or changed

The circular saw blade, in turn, fits perfectly onto the standard shaft and does not need to be replaced. There won't even be a need to sharpen it. When it hits a stone, a very sharp sound is immediately heard. If the disk is immediately moved to the side, nothing will happen.

Option two is to replace the disk with metal wire. Alas, it will not justify itself either. The grinder produces about 11 thousand revolutions per minute. When putting the wire on, a strong vibration immediately begins, the handle of the hoe simply jumps out of your hands. In addition, this whole process is accompanied by terrible noise.

The benefits of such a trimmer are obvious. However, for those who doubt it, there is one more argument: the grinder remains absolutely functional, and at any time it can be removed and used for its intended purpose. Two in one, as they say.

Types of cutting attachments used

Homemade products, like factory units, are equipped with cutting attachments of various types:

milling-turbine (universal).

The first type is flat blades. When they rotate, they grind plant debris. If you have to process branches, then such blades quickly become dull. Milling knives are a cutting shaft in the form of gears from circular saws. They grind dry waste from branches and grass well, and clog the cutters with wet waste. Milling-turbine cutting attachments can cope with thick and undried branches, but making them yourself is difficult.

At home, knives from lawn mowers or made from wood saws are often used.

It should be taken into account that the degree of processing of plant waste directly depends on the installed cutting attachments. The output is pieces of branches from 10 cm long or shavings or dust.

Preparatory activities

A grass cutter from a brush cutter is manufactured in a number of stages. Initially, they are prepared in a container where the grass and branches will be ground:

• make markings on the bottom (along the perimeter) for four trapezoidal holes with rounded corners;
• drill holes with a cross section of 1 cm in each drawn segment;
• a jigsaw file is inserted into them and trapezoids are cut out;
• process the cuts with a file or sandpaper;
• a hole is drilled in the center of the bottom for the chopper shaft;
• a circle is cut out of steel mesh with dimensions according to the diameter of the bottom;
• using small scraps of boards or blocks, the prepared mesh fragment is secured to the container from below;
• Legs for the container are made from metal tubes, attaching them to the tank with bolts.

The wooden pieces are fixed with self-tapping screws, twisting them from the inside of the tank into metal jumpers between the cut trapezoids. In this way, the mesh is securely attached to the bottom of the container.

• bend the tubes in a vice or using a pipe bender in the shape of the letter “P”;
• the ends of future supports are flattened with a hammer;
• 2 holes are drilled into them on each side (6.5 or 8.5 mm cross-section);
• fit the workpieces to the bottom of the container and mark the points of bolted connections;
• drill according to the hole mark;
• using bolts with washers and nuts, attach to the footrest casing.

After preparing the casing, in order to reduce the dimensions of the created mechanism, the following operations are performed:

• disassemble the trimmer, disconnecting the motor, rod and cutting attachment from each other;
• cut off a fragment approximately 20-40 centimeters long from the rod with the cable;
• collect the lawn mower;
• check the performance of the equipment.

Design and principle of operation

A screwdriver can be used in various fields of activity and for various actions, for example, in everyday life, during construction, assembling and disassembling furniture, in various workshops and where many fasteners are used. They can drill, make threads, tighten and unscrew fasteners. Let's get acquainted with the device and operating principle of such a mechanism.

All screwdrivers are divided into three types:

• operating from a regular network and called network;
• operating from a charged battery and called rechargeable;
• operating both from the mains and from the battery - a combined option.

All screwdrivers are very similar both in external and internal structure. They consist of elements such as:

• frame;
• cartridge;
• power button;
• rotation switch;
• speed controller;
• power lock button;
• tension regulator.

Some models additionally have backlighting, while some lack one or another element. Thus, mains-powered models have a power cord, while battery-powered models have a charge storage device.

The body of a power tool consists of two parts and can be made of plastic or an alloy of various metals, but this is much less common.

Inside it are:

• electric motor;
• pay;
• capacitor;
• gearbox;
• coupling

The principle of operation of all screwdrivers is similar to each other - the electric motor is driven into rotation using the consumed electricity, which transmits force using a gearbox and shaft from the motor to the existing nozzle installed in the chuck, and the nozzle already carries out the process of drilling, screwing in or unscrewing fasteners. In corded screwdrivers, the motor uses an alternating mains voltage of 200 V, and in cordless screwdrivers, the motor uses a constant voltage from 3.5 V to 36 V.

Replacing the nozzle is also quite easy and simple. In this case, the screwdriver can have a keyless or key-type chuck.

Changing the attachment with a quick-release chuck:

• first you need to choose a drill for the work you plan to do, or a bit, taking into account the size of the head and the type of slot;
• the cartridge is untwisted counterclockwise;
• install the selected nozzle;
• By rotating the cartridge sleeve in a clockwise direction, the nozzle is clamped.

Changing the nozzle with a turnkey chuck:

• take the key and insert it into a special recess;
• unwind the cartridge;
• insert a new nozzle;
• rotate the key in the direction of movement clockwise, securing the nozzle.

Where to start work

1. To convert a screwdriver for power from a 220 V electronic network, first of all, you will need to solder an electronic wire to the contacts of the charger . Alas, because the wire has copper conductors, and the power supply has brass terminals, it will be very difficult to connect them. However, there is nothing impossible in the area, so we use acid as a connector. You need to treat the terminals of the charger , then solder the wire to the contacts. The connection will be of high quality, because the contact and functioning of the device itself depends on it.
2. Next, the old battery is rebuilt. For this purpose, it must be disassembled and the entire internal part removed with its use. Although the manufacturer does not recommend doing this, the design of the battery will be useful to us. When disassembling the battery, it is important to use protective equipment and not even throw the internal filling in the trash, but rather recycle it. A weight should be placed in the battery case, which will act as a counterweight.
3. If the inside of the battery is removed, we begin the process of soldering the free contacts of the electronic cable to the battery terminals located in the inside of the case.

Fundamentally! During soldering, it is important to keep polarity under control; if it is not observed, then nothing terrible will happen, only the device will work in the other direction. Alas, using a switch this situation can be easily resolved.

The electronic cable is inserted into the battery from the outside, making a special hole in the structure of the required diameter. When you get tired of this, it’s important to make sure that the cable is firmly fixed in the structure of the battery case. For this purpose, at this time you need insulating tape, using which you should wrap the cable on both sides, thereby making a lock. Then we insert the battery housing into the screwdriver and use it for its intended purpose.

Precautionary measures

After remaking a screwdriver, it is important to adhere to the following precautions:

• Provide the device with a rest every 20 minutes of operation, which will extend its service life;
• It is harmful to work with the device at a height of more than 3.5 meters from the ground;
• Clean the power supply
  from dust from time to time;
• Please pay attention to the fact that the electronic cable during operation is not pinched, strained or succumbed to negative factors, which leads to the creation of a short-circuit current.

After the alteration, following the safety rules, the old screwdriver will last longer than the new two.

Hello! Please tell me how to make a screwdriver from a drill?

It’s impossible to make a full-fledged screwdriver. These devices have different purposes and different mechanisms.

The screwdriver has a so-called ratchet. This mechanism stops the process of tightening the screw in time. This means you won't drive the screw deeper than necessary. The drill does not have such a mechanism, which means it is very easy to tear off the slots on the screw. And then it will be extremely difficult to get it.

Another nuance is the inertial rotation of the chuck on the drill. On a screwdriver, rotation stops immediately after removing your finger from the trigger. But after switching off, the drill will continue to perform rotational movements for some time.

The electric motors themselves are also different for both instruments. If used frequently for other purposes, the drill motor may become unusable.

If you need to tighten several screws, you can use a drill. To do this you need to have some experience working with it. Basic Rules:

• The drill must have a speed regulator.
• You need to set the lowest speed.
• We use a special bit for screws.
• You need to feel the twisting process with your hand.
• Raise the drill in time to avoid breaking the tool.

A little advice. It is better not to tighten the screw all the way. Leave a few millimeters and tighten it manually with a screwdriver. The point here is this. If you screw it into a soft material, such as wood, the screw will go very deep. If you use a harder version, you will either twist your arms or rip off the gearbox in the drill itself.
