Crafts from an old screwdriver. How to make a boat motor with your own hands from a trimmer or screwdriver. Use electric motors from household appliances

A friend has a BOSCH GSR 12-2 Professional screwdriver, he’s had it for a long time, but it rarely works, and the batteries began to die intensively, back in the fall, let me tell you, I’ll revive it over the winter, there’s plenty of time and options, restore old cans by pouring distilled water into them water and after training them, replace the dead cans, if there are few of them, convert them to lithium. But no, I say they don’t work enough for me, the capacity is enough, as a result, both batteries died at zero volts by spring, I started the battery with a charger, but there is still no capacity, buying new ones is like buying a new screwdriver, changing nickel-cadmium banks too not cheap and not for long, as a result I get the go-ahead to convert to lithium. The owner is a pensioner, so we try to save money, and he uses it occasionally. I am ordering a BMS 4S 15A from ALI, so that I can later convert it into a 3S according to the scheme.

Oddly enough, the 4S costs less than the 3S, the vision is certainly not the same, but it was still redone, and 100-150 rubles. saved. I also ordered 6 high-current folk batteries. Samsung inr1865025rm 20a is just for two battery packs. They arrived and checked the capacity at 1A current.

It seems good, and the reviews from the seller are quite good.

There is a lot of information on the network about modifications, but the boards for three and four batteries are slightly different; if the board has 4 batteries, then you need to put 4 or convert it according to the scheme for 3 batteries. I did it according to this scheme, because the screwdriver itself is 12 volt.

The capacity of each assembly is like two new Ni-Ca (the old ones in theory 1.3 Ah), the old and new batteries were secured with hot glue, the battery was soldered and not welded, I know that it’s not feng shui, but I didn’t overheat, it will work like that;) and I didn’t redo the charging ( it works in normal mode, all the indications correctly show both charging and the end of the charge), it turns like new and better, I didn’t install a balancer on the battery, it’s at least another 300 rubles, better in a year or two I’ll take it apart and balance it manually. This is how the screwdriver got its “second wind”.

Converting a screwdriver to a network one

When the batteries do not hold a charge and have exhausted their service life, and the screwdriver is still in good condition, it can be connected to a 220V network through a power supply with sufficient power.

Everyone is familiar with a screwdriver. This is a hand-held power tool designed for tightening and loosening a variety of fasteners. This is the main direction of its application, but not the only one. Using a screwdriver you can create a great variety of useful and necessary things.

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 for charging mobile phone or running a small LED lamp.

Harnessing wind power with a screwdriver

Wind generators are built using this principle using a screwdriver, but the current generated is so small that the game is not worth the candle. Its installation is more effective in areas of high wind load, although even there the result is not justified.

Carpentry workshop equipment

A few more interesting suggestions on how to make equipment for home carpentry using a conventional 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. Tailstock made from 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. Primitive lathe ready for home workshop.

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 thread. 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 hand-held 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, locksmith tool and a feather drill bit for wood. In the latter case, you can use a drill bit.

Collect homemade router pretty 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.
• At the base using feather drill drill a hole Ø 40 mm for free access 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 replacement hand router due to low power and low spindle speed, but it will solve the issue 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 chipboard sheet or thick plywood. You need to make a cut in the countertop to get out circular saw. 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 work surface table no more than a third of its diameter.

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. Steel frame profile pipe. You can make it yourself.
2. Wheels can be used from a rubber garden cart.
3. The body can be taken from an old pedal car or you can 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 can be called an electric scooter or an 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 battery hand tools. 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 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.

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 automate opening entrance gate, make a winch for a car or 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 apply this hand tool to create carpentry workshop equipment, improve children's vehicles and other useful household items.

More and more anglers are thinking about installing a motor on a boat. It allows you to speed up movement across a pond and relieve your hands from hard work with oars. When a man’s physical strength becomes less, ingenuity comes to the rescue. It turns out that you can make a boat motor with your own hands from various household appliances. For those bodies of water where use is prohibited gasoline engines, as driving force electric current is applied. In other cases, it is better to choose devices with gasoline power units.

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.

1. 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 it on board car battery 12V. 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.

1. 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 craft. 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.

Making an engine from a screwdriver

Good homemade motors for boats are made based on cordless screwdrivers. It is optimal to use a device with a battery voltage of 12V. It will be possible to connect a car battery with a capacity of 45-55 Ah to such an electric motor. Refinement will consist of several stages.

Lifting mechanism

The propeller of an electric motor for a boat made by yourself must move not only in a horizontal plane, but have a certain immersion limit and rise completely out of the water. The simplest design would be a system of clamps to which the engine is mounted. It is rigidly attached to the transom using a steel frame and plate. The clamps are equipped with rings through which the tube will pass. There will be a shaft made of steel wire or rod running inside. To ensure easy sliding, suitable fittings are pressed inside the tube. overall dimensions bearings.

Gearbox and propeller

The screwdriver is capable of developing high speeds, which is required when drilling. Homemade electric motor a boat does not need such high speeds, so a gearbox is installed to reduce them. Most suitable option becomes the connection of the gearbox from the grinder. In the screwdriver chuck, just clamp top part shaft to ensure a secure connection.

The role of a propeller can be played by an impeller from a car pump or a computer cooler. But such a home-made electric motor will not be able to provide the boat with the required speed. You can make a propeller from a piece of stainless steel 2.5-3.0 mm thick.

1. First you need to cut out a square blank measuring 30x30 cm.
2. A square with a side length of 5 cm is marked in the center. Diagonal lines are drawn through the corners. The cut will go through them to a small square.
3. Each petal should be rounded and rotated along its axis by 30 degrees.
4. A hole is made in the central part for attachment to the gearbox.
5. All that remains is to reliably connect everything and test the resulting boat electric motor with your own hands.

Refinement of lawn mowers

The boat motor from the trimmer requires a little modification to get a workhorse for the watercraft. Dignity petrol trimmers is low price and maintainability. Homemade motors for boats, 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.

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

1. 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.

Advice! During testing, necessary adjustments can be made. At low speeds, the blade is trimmed or the propeller pitch changes.

1. 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.

Manufacturing of fastenings and installation on the boat

Homemade boat motors require special mounting. The principle of its manufacture looks like this.

To reliably install a boat motor from a brush cutter, you need to use a ring to which the belt is mounted. To connect the braid to the transom, you can use an old manual meat grinder. The lower part is cut out of it, and a 12 mm thick hole is drilled in the transverse plane of the body. It is important to carry out some modifications with a pin with a diameter of 12 mm and a length of 10 cm. One side is flattened, a hole 6 mm thick is drilled in it. An M6 bolt is inserted into it, then the eye of the lawn mower is inserted and the nut is screwed on.

Installation homemade installation to the ship is carried out in the following order.

• A homemade mount is mounted on the transom of the boat using a stud and a corresponding nut.
• Now the engine is installed and secured using a threaded connection. It remains to check how it turns on the boat in different directions.

Homemade motors for boats are not only an opportunity to increase the speed of your boat. The manufacturing process will allow the brain to turn on at full speed, as a result of which another folk invention may be born.

We expand the capabilities of a portable screwdriver with our own hands.

Working with thin drills with an electric drill is almost impossible. One careless movement and the drill is broken.

Meanwhile, it may be necessary to drill holes in hard to reach places, where you can’t get to with .

You have to drill by hand, holding the drill in the holder. However, with help you can solve this problem. You only need to sacrifice one bit (the screwdriver insert), cut it on the grinding wheel as shown in the picture, and connect it to the miniature chuck.

Fitting the bat to the chuck is quite simple. Place the bit in the screwdriver, turn it on and carefully move the rotating bit towards the grinding wheel. When grinding, try not to move the screwdriver; it is better to press it against the grinding wheel support.

The slow rotation of a screwdriver, compared to a drill, is even useful. It is easier to control drilling; the drill does not heat up during operation and does not weld with plastics.

Of course, you won’t get deep drilling, especially in metal - you need it for that, but in many other cases such modification of the screwdriver can be useful.

The ability to make a windmill from a used screwdriver has not only a theoretical, but also a practical basis, however, it is worth thinking about the end result.

The screwdrivers available for sale today are quite powerful tools; its operating voltage, when charged from a battery of 18 volts, can provide about 40-50 watts of power as a generator. Such power will allow you to light a couple of LED light bulbs, this is when the wind is blowing, and what if it’s calm?

If we are talking about free time and disposal of trash, then it makes sense to expand the activity. If you need a working model, then a windmill made on the basis of an axial disk generator will generate more energy.

The process of turning a screwdriver into a home windmill is useful in accumulating general information in the field of physics, aerodynamics, and electronics, which is also educational and interesting.

Components

All that can be useful is the rotor from that same screwdriver.

Other missing parts will have to be purchased, these are neodymium magnets of suitable dimensions, various rectifiers, converters, inverters and charge controllers.

Or find, for example, chain reducer to correlate the rotation speed of the rotor and generator.

Something to get - bearings for the blades.

The result will be a wind generator with a power of 30-40 W at a wind speed of 5-7 m/s.

But that’s not all, you need to make it yourself:

• blades: from scrap materials, aluminum sheets 2-3 mm thick;
• casing: protective general design from bad weather;
• wind generator tail: turns it in the direction of the wind;
• support mast made of pipes: on which the wind generator is mounted.

No less important is the issue of manufacturing blades of a certain shape; for this purpose, the problem of aerodynamics is solved.


To obtain useful operating power, the windmill blades must be 1.5-3 meters long, and for this you need usable area. When bolting them to the generator, it is necessary to very accurately calculate the position of the fasteners in order to have a correctly balanced, adjusted rotation of the blades.

Here a reasonable question arises: is a windmill made from scrap materials and a screwdriver worth such labor and effort, especially since its payback tends to zero. If we compare the costs of making a windmill with our own hands and the cost of a ready-made standard wind turbine (wind power plant), the second option is more preferable.

Preliminary preparation

When constructing a windmill with your own hands from improvised means, if the goal is to have a working, useful device for the household, and not a reminder of a thoughtless desire to create something, it is necessary to calculate the dependence of the possible initial power of the installation on the wind speed.

It should be taken into account that the wind power is directly proportional to the area of ​​the surface being blown and the wind speed raised to the 3rd power. The simplest arithmetic will show that the energy received is only sufficient to charge a mobile phone.


Before you begin the process of manufacturing a device “so useful” for home use with your own means and your own skillful hands, you should determine the characteristics of the accompanying parameters:

• wind speed and its main seasonal directions;
• surrounding area;
• type of wind generator;
• social aspects.

When building a windmill from a screwdriver, it is advisable to choose a horizontal-axis type of wind generator, since the axis of rotation of a windmill of this type can operate in any wind direction. The tail blade of this design balances and turns the working head of the structure on the mast in the direction of the wind.

Power generated by a wind generator horizontal type is directly proportional to the height of its mast, since at a height of 6-10 meters the wind speed is greater than at lower levels. There is also a “but” here, such an installation cannot be located in close proximity to buildings. It is better to place it at a distance of about 300 m from a residential area, where there are no trees, or better yet on a hill, in which case problems with servicing the windmill and its safety begin.

Service

Like any mechanism, a wind generator, even one made by yourself, needs some maintenance.

For example, in case of sharp gusts of squally wind, the installation must be equipped with a braking mechanism, purchased in a store or also made by hand, in order to avoid destruction of the structure.

Other protective measures, this is a mandatory grounding of the mast and the presence of switches so that you can approach the structure if necessary.

We cannot ignore the harsh climatic conditions in winter, since during this period the blades or pipes of the generator may freeze and cause an accident.


There is no need to talk about lubricating the rubbing parts of the windmill, since the wind generator itself is already a source of noise, albeit small, and the additional grinding and creaking of other parts of the installation can cause upset not only among neighbors, but also among family members of a home-grown designer who, with his own I created discomfort for myself and my loved ones with my hands.

Conclusion

Taking the opportunity and creating a device with your own hands to use practically free, otherwise God-given energy, especially if you are far from civilization or just want to save money, is very commendable, but economic justification begins at a wind speed of at least 4 m/s.

I would like to ask the home-grown Kulibins whether it would be better to buy a standard wind turbine for almost the same money. Such an installation can be assembled in 2-3 hours, generates electricity at a wind speed of 1-2 m/s and has a payback period of 5-7 years.
