Do-it-yourself impact screwdriver from the starter. Convenient and practical impact screwdriver from a car starter Homemade impact screwdriver from pipes

An impact screwdriver is an indispensable tool in those frequent cases when the task is to unscrew a rusted or overtightened screw or self-tapping screw. A conventional screwdriver will not work for unscrewing rusted screws or self-tapping screws, as attempts will either break the screw slot or damage the tool tip. Particular difficulty arises in situations where a steel screw for a screwdriver is screwed into an aluminum part. Under the influence of corrosion, the two materials adhere tightly, as a result of which only an impact screwdriver can cope with the task.

Impact screwdrivers, which are produced by production, differ from each other in technical features and equipment. The main difference between an impact screwdriver and an ordinary tool is the presence of a reinforced metal case. Moreover, this body is several times larger than the design of a standard tool. According to the technical characteristics of the products in question, they differ:

• The presence of a reverse. A good screwdriver will certainly be equipped with the ability not only to break the connection, but also to tighten it. Screwdrivers from the times of the USSR do not have such a function, so this is typical for advanced modern models.
• Handle design. The handle is not only a handle, but also the body of the tool.
• Body material. Often, tools are presented in a steel case, and more expensive models cover the structure with polyurethane, rubber or polyethylene.

The scope of these tools is quite wide. These tools will be indispensable not only in household use, but also in various workshops, especially where car repairs are carried out. The swivel screwdriver allows you to use it not only for unscrewing rusted screws, but also for screwing them in securely.

The main characteristics of the tool are presented above, but it is important to mention the varieties of screwdriver tips. Impact rotary screwdrivers are almost always equipped with interchangeable bits. Each set most often consists of a screwdriver and four different bits (two Phillips and two flat). The use of these tools is so effective that every self-respecting craftsman must have such a power screwdriver. In addition, it is just as easy to use as usual.

How the tool works

The principle of operation of an impact screwdriver is based on the impact on the body of the tool while turning the bit in the right direction. To do this, the body is made of high-quality steel, which can easily withstand hammer blows. When strikes are made on the handle with a hammer, the clip with the bat moves to the side, thereby displacing the “sticky” screw from its place. The angle of rotation of the clip when making strikes is insignificant, but this is enough for the screw to be “torn off”. The screw is tightened in the same way.

The tool in question is intended solely for "breaking" or tightening screws. After the fastener is "torn off", you should use the usual tool.

To increase the efficiency of unscrewing the fastener, it is important to select the nozzle as accurately as possible. Due to the double action on the fastener (straight along the axis, and turning to the side) when making blows, the self-tapping screw, screw or bolt is unscrewed.

How to use the tool

Although the tool is the easiest to use, it is important to know some important rules when working with it:

• An impact screwdriver provides the most accurate selection of the appropriate nozzle for the fastener. If the nozzle is not selected exactly, this will lead to the folding of the slot of the fastener.
• Although a screwdriver is an effective tool for unscrewing rusted and stuck fasteners, it is important to facilitate its work and prepare the screw to be removed. To do this, it is necessary to treat the screw part with brake fluid or WD-40 grease. After processing the connection, you should wait 5-10 minutes, and then proceed to action. Sometimes, after treatment with such lubricants, it is possible to unscrew the fasteners even with a conventional screwdriver.
• We insert the screwdriver into the slot of the fastener strictly at a right angle, without distortions and hold it with one hand.
• Next, with the other hand, you should strike with a hammer on the butt. It is important to use a hammer weighing 300-500 grams.
• The blows must be light and hard, otherwise the effectiveness will be zero.
• After 2-3 strokes, check for shifts. If there is no shift, then pay attention to whether the slot of the fastener is licked.

Is it possible to do it yourself

You can make an impact screwdriver with your own hands, since structurally it does not present any particular difficulties. If from the above material you understand how the tool works, then you can start making it. To do this, you will need the following details:

• Rotor from an electric motor. All you need is a shaft and a bushing. It is best to use the rotor from the starter by removing the winding from it, as shown in the photo below.
• After removing the winding, only the shaft and sleeve remain. A piece of steel tube must be put on the shaft, which will play the role of the tool handle.
• On the reverse side of the pipe, put on a nut, which will be hit with a hammer.
• The resulting parts must be welded together, resulting in the following tool.

As you can see, making an impact screwdriver with your own hands is not at all difficult, especially if you have a scheme for manufacturing. Such a roll of homemade products not only makes life easier, but also allows you to significantly save money. To be able to apply various nozzles to your homemade tool, you will need to sharpen the end part of the sleeve for an adapter or the necessary nozzles.

In conclusion, it remains to be noted that the resulting device is quite reliable and even almost eternal, since the starter parts are made of hardened high-quality steel. Periodically, it is required to check the lubrication of the splines on your homemade product. The price of the most inexpensive impact screwdriver is about 500 rubles. When choosing, carefully look at the completeness and workmanship.

Having trouble loosening rusty bolts? I suggest you try to make a screwdriver yourself, which will allow you to unscrew almost anything!

Sometimes there are cases when it is necessary to unscrew a heavily rusted bolt or, for example, screws with stripped edges. You can't do it with a normal tool. And here such a simple tool will come to your aid, which you can easily make yourself. I will tell you how to do it using the example of a rotor from a faulty Zaporozhets electric starter.

First of all, we cut off the part of the rotor shaft on which the winding is located (see photo 1), and then, with the rest, remove all unnecessary.

As a result, we get only the shaft and the sleeve (see photo 2).

We put a piece of pipe on the sleeve, which will serve as a handle for us. From the other end, we insert a plug from the trim of a large bolt into the tube, which will not allow the handle to be deformed due to hammer blows and in parallel will limit the shaft travel inside this sleeve (see photo 3).

Then, using electric welding, we weld all the details (see photo 4).

We sharpen the end of the shaft in the shape of a square so that it is possible to put on various heads (for bolts). If it is necessary to unscrew the screw, the corresponding bit must be inserted into the head. The principle of operation of a screwdriver is simple: when a hammer strikes the end of the handle, the shaft begins to turn slightly on the oblique slots inside the handle. This is quite enough for the dried bolt to break off.

Due to the fact that all parts of the electric starter are made of high-quality steel (it is necessary to cut with a grinder), the screwdriver is quite powerful and durable. You should not do strong blows with a hammer on the handle, because the heads of the screws or bolts will break off. And in order for the splines to serve you faithfully for a long time, they must be constantly lubricated.

Note! For the manufacture of this screwdriver, an old starter from almost any car is suitable. And the larger, the more powerful your tool will turn out.

An impact screwdriver is a fairly popular tool that is used not only by professional builders, but also by amateur craftsmen for household chores. It is indispensable for unscrewing firmly "welded" screws.

Ordinary screwdrivers are useless in such cases, and impact drivers allow you to combine hammer strength and torque in one tool. So how do you make your own impact screwdriver using a car starter?

What is an impact screwdriver

There are practically no visual similarities between an impact screwdriver and a standard one. This tool is a shock-turning mechanism that allows you to convert the force of impact into torque. With the help of it, the installation and dismantling of threaded connections for which additional efforts are required is carried out. Using a conventional screwdriver for these purposes will break the tool or damage the element to be dismantled.

According to its principle of operation, an impact screwdriver resembles a bolt. In the process of work, the locksmith has to hold the handle of the screwdriver with one hand, while with the other he hits with a hammer on its end part.

Principle of operation

By its principle, the operation of the tool is quite simple and there are no difficulties when using it. After hitting the end surface with a hammer, the element on the bottom of the screwdriver rotates. This rotating force is enough to dismantle strong fasteners.

To simplify the workflow, you can pre-lubricate the fasteners with brake fluid. After that, you need to install the tool at a right angle to the head of the hardware and use a hammer to strike at the end of the screwdriver. After turning the fastener noticeably, you can continue unwinding with a conventional screwdriver.

Even a person with no experience can work with this type of tool. However, in order to make an impact screwdriver, you need an idea of ​​how it works and the availability of the appropriate parts from which it will be made.

Do-it-yourself impact screwdriver from a starter

To create this simple tool at home, a faulty electric starter from a car is suitable, which is not difficult to find today.

First of all, we need to cut off the part of the rotor shaft where the winding mount is located.

We remove unnecessary elements from the rest so that only the shaft and sleeve remain, which we will use as the main mechanism.

As a handle, you can use a small fragment of the pipe, in which we must place the sleeve on one side. And on the other hand, we need to insert a plug, which will also be a shock heel. We use a large bolt as it, it will prevent the tube from deforming during impacts and will limit the displacement of the shaft inside our sleeve.

The next step is to weld all the details.

Finally, at the end of the shaft, it is necessary to make a square sharpening for the possible change of various nozzles. So to unscrew the screw or nut, it will be enough to insert the desired bit and dismantle the fastener. If it is necessary to unscrew the screw, the corresponding bit must be inserted into the head.

It is worth noting that the electric starter is made of high-quality types of steel, so you will have to use a grinder to cut it. But due to its strength and hard alloy, the tool will be quite powerful and durable, and in some respects it will surpass even factory products. Periodic lubrication of the splines will help increase the service life of such a tool. However, it should be used carefully, without applying strong blows, so as not to break the heads on the screws or bolts.

Of course, the resulting product will be less presentable than a factory screwdriver, but its cost will be minimal and in terms of reliability it will not be inferior to the factory counterpart.

Advantages of a homemade tool

• The screwdriver is equipped with a reinforced case made of high-strength steel.
• Differs in the big sizes in comparison with factory screw-drivers;
• The operation of the tool is safe for a person if it is struck correctly with a hammer. Observing the safety rules, it is impossible to get injured and injured with a screwdriver;
• There is the possibility of changing nozzles, based on what type of work is being carried out;
• It is easily made at home without significant physical and financial costs;
• Multifunctionality. It can be used for various tasks in the field of construction, automotive, and any other craft.

Quite often there is a need to unscrew heavily rusted fasteners. What to do in such situations when a standard household tool cannot cope with the task? What to do in this situation, because household tools do not cope well with this task. For this, a good solution would be to use an impact screwdriver. Thanks to it, unscrewing rusted parts will not be difficult. It is enough to moisten the fasteners with brake fluid so that the part can be unscrewed as easily as possible during dismantling.

However, in some situations this does not help. There is no need to panic. Try lubricating the bolt again with brake fluid and leave it for a while. The liquid will corrode the stagnant texture and with the help of a percussion tool you can do everything without significant effort.

Conclusion

As we can see, impact screwdrivers have a fairly simple principle of operation. These are useful and necessary tools that should be in the tool kit of every craftsman, so that if necessary, you can always unscrew rusted bolts. which will easily help to unscrew even the most obsolete bolts. If you decide to make an impact screwdriver with your own hands, then you can be completely sure of the quality of the finished product, which is in no way inferior to specialized factory models.

Video "We make an impact screwdriver in a home workshop"

Impact screwdriver today is a very popular tool not only in construction, but also for work at home. It will be simply irreplaceable in those situations when it will be necessary to unscrew the firmly "welded" screw. An ordinary screwdriver in this case simply cannot help you in any way, but an impact screwdriver is a completely different matter.

What is this instrument

If you look visually, there are very few similarities with the screwdriver we are used to. This model has a metal case, which makes it more durable and even allows you to withstand strong blows with a hammer.

A set of impact screwdrivers usually comes with two bits: a flat head and a Phillips head. The connecting part where these nozzles are installed has the shape of a square. In fact, it is very convenient for the reason that you can fix socket heads into it, which will give you the opportunity to work with bolts, self-tapping screws and screws without much effort. This is especially good for the category of people who are constantly engaged in car repairs.

Using an impact screwdriver, you can not only unscrew the fasteners, but also install new ones in their place. It is worth noting that this tool twists the details "for centuries". Believe me, you will not be able to then unscrew the bolt with a regular screwdriver.

The principle of an impact screwdriver: how it works

The principle of operation of the tool is not as complicated as it might seem at first glance. When there is a hammer blow on the end, the lower part begins to rotate with such force, which is quite enough for the nozzle to cope with the most durable fasteners.

Brief instruction:

• In order to simplify your task a little, before starting work, you can slightly lubricate the fasteners with rags previously moistened with brake fluid.
• Next, we take our screwdriver and set it perpendicular to the head of the hardware.
• We take a hammer in our hands and hit the end of the tool with all our might.

After the fastener begins to rotate around its axis, make a few more blows with a hammer. This is necessary in order for the screwdriver to switch back to the "twist" mode. As you can see, it's not that hard to figure out how to use an impact screwdriver.

We make an impact screwdriver with our own hands

Oddly enough, you can make this very useful tool at home without much effort. The main thing is to figure out how an impact screwdriver works, then the work will go much easier.

Let's get to work:

• Prepare a rotor taken from an electric motor (small). Everything must be cut off from it in such a way that only the shaft and sleeve remain.
• We take the sleeve and select a piece of metal pipe that is suitable in size to put on it. This will be our handle.
• On the reverse side, you will need to insert a nut that is larger in size. This will give the handle strength and not break when hit hard with a hammer.
• All parts are welded together.
• We sharpen the end of the shaft well so that it acquires a square shape.

Our homemade tool is ready. It only takes a little effort, and trust me, an impact screwdriver will turn out just as good as any store-bought model.

Advantages

• It has a reinforced body made of steel.
• Largely larger than a conventional screwdriver.
• Has a twist switch. This is very convenient if you need to tighten a bolt or unscrew a rusty part.
• Using an impact screwdriver is absolutely safe for humans. It cannot hurt you and cause other damage to you.
• It is possible to change nozzles, depending on the case. With only one tool at home, you will always have both a cross-shaped nozzle and a flat one at hand.
• You can make it at home without much effort, and this is a significant cost savings.
• It can be used not only in construction work, but also in car-related repairs.

There are times when you need to unscrew heavily rusted fasteners. What to do in this situation, because household tools do not cope well with this task. All you need is an impact screwdriver. It is hard to believe that she is able to unscrew the outdated part.

Moisten the bolt with a little brake fluid and see how easily the part comes off. Of course, it happens that this does not help either. You should not despair. Moisten again with the fluid that you use for the brake system of the car, and leave for several hours. After that, you can use an impact screwdriver to do the desired work.

The tool can be purchased at the store or made at home. In any case, in addition to the body, you will need additional nozzles. This will save you from unnecessary tools. Imagine how nice it is when instead of ten screwdrivers in a box there is only one - impact, and nozzles are attached to it, which will help you in any construction situation.

What are impact screwdrivers?

Main types:

• Tool in the form of a simple beard. It is very easy to use it. The biggest advantage of such models is that they are very cheap and absolutely everyone can afford it.
• Like a regular screwdriver. If you put two screwdrivers side by side - impact and standard, then you will not be able to find visual differences. However, our tool is equipped with a special mechanism inside, thanks to which it is possible to cope with difficult situations during construction and repair. However, if we talk about the cost of such models, they are quite expensive.
• Handmade impact screwdriver. The best and most economical option. If you have a little time and desire, then with the help of simple details you can make a very useful tool for the household with your own hands.

Summarize

As you can see, an impact screwdriver has a very simple principle of operation. This is a useful and necessary tool in the arsenal of any mechanic, which will easily help unscrew even the most obsolete bolts. Having made it with your own hands, you will work with pleasure. Be sure that you will get it no worse than models from specialized stores.

Quite often, during plumbing work, one has to deal with rusted bolts, screws, self-tapping screws. Trying to use a conventional screwdriver either fails or runs the risk of stripping the screw slot or damaging the tip of the tool. Of particular difficulty is the unscrewing of steel bolts from aluminum parts, since over time, corrosion makes such a connection practically inseparable, and the materials “stick” to each other.

To solve such problems, a tool called an impact screwdriver was invented.

The history of the impact screwdriver

The simplest impact screwdriver is a tool with a monolithic core, starting with a sting and ending with a massive heel on the handle. Such a screwdriver, which had a handle with two wooden plates, has been known to everyone since Soviet times.

In modern models, near the sting or on the handle, the core has a hexagon, which allows you to transfer the rotational force from the key. Two people are recommended to use this tool. One person holds the tip in the slot of the screw and creates torque with a wrench. The partner strikes with a hammer on the back of the handle.

In using this tool There are two main downsides:

1. They can only work effectively together.
2. There is no conversion of impact energy into torque. Hammer blows only help loosen, as they help break down rust and create vibration.

To eliminate these shortcomings, a rotary impact screwdriver was created. This tool is already a mechanism that allows you to transform the force of impact into the rotational movement of the sting.

The device of the impact screwdriver mechanism, the principle of operation

Hereinafter, by the term "impact screwdriver" we mean impact screwdriver, since this is the name assigned to this tool.

The shock-rotary mechanism is located in the handle. The tip is rigidly connected to a gear having oblique teeth. The handle is a clip with reciprocal teeth. When a hammer strikes the heel of the handle, the clip moves along its axis and imparts a rotational movement to the sting through the gear train. The rotation is only a few degrees, but this is enough to loosen the connection and complete the unscrewing with a conventional tool. After the hammer strikes, the clip returns to its original position with the help of a spring.

work with such a tool simple enough. The mechanism provides a combined translational and rotational force on the screw slot, which is most effective for successfully loosening stubborn threaded connections.

Varieties of impact screwdrivers

Commercially available models may differ from each other in technical characteristics and equipment. Let's take a closer look at these differences.

Specifications

Here we will not consider the quality of workmanship and the reliability of the materials used. It is clear that models from well-known manufacturers are made of "correct" steel, which has the necessary hardness and strength.

It is more important to note that more advanced models equipped with reverse. They allow not only unscrewing rusted connections, but also making a strong tightening of the screw where it is required by the fastened structure.

Another important point is the device of the handle, which acts as a handle for holding and the body of the mechanism.

The steel case is the most reliable, allows clearly control the work process and optimal dosage of efforts.

If an overlay made of polyurethane, rubber or polyethylene is placed on the steel case, the screwdriver is much more convenient to hold. When the lining has a tide in the heel part, the safety of operation is increased. Manufacturers can go one of two ways:

1. The body dimensions remain unchanged. The tool has high reliability, but is not suitable for work in hard-to-reach places and cramped conditions.
2. In order to increase ease of use, the dimensions of the metal case are reduced, which negatively affects the reliability of the tool.

The choice of the most suitable option remains with the buyer.

Equipment

It is inefficient to issue a separate impact screwdriver for each slot. Most often, the tool is use of universal nozzles. The screw-driver is completed with the cartridge holder for standard bits. The kit may contain both a pair of nozzles and a decent set.

On sale are widely represented nozzles for various slots and hexagons. When purchasing them, special attention should be paid to the quality of workmanship. Quality and reliability are especially important in view of the effects of shock loads.

Advantages and disadvantages of an impact screwdriver

The most important benefits impact screwdriver are:

• Impact energy efficiency.
• Significantly less required impact force. A conventional impact screwdriver without a swivel mechanism requires both stronger impacts and more of them.
• Possibility of use by one person.

The disadvantages are not so significant with proper operation, but it is also important to remember them:

• Risk of breakage of the impact mechanism. The simplest impact screwdriver has many times more survivability due to the monolithic design. Excessive impact on the impact screwdriver should be avoided.
• Depreciation of the mechanism. Gear teeth and cages are subject to friction associated with shock loads. During operation, their resource is reduced.

Rules for working with an impact screwdriver

To simplify the process of unscrewing as much as possible, you need to follow some simple rules:

If the tool has a reverse, some experts recommend that after the first displacement of the screw head, set the twisting mode and make a couple of blows, and then unscrew the hardware again. This is explained by the fact that with this approach, rust is even better removed from the thread.

It is also important to observe safety precautions:

• Keep the handle in good work gloves or gloves that prevent slipping.
• Do not strike excessively hard. A hammer weighing up to 500 grams is quite suitable.
• Hits should be light. Do not tilt the hammer, otherwise the head may slip off the screwdriver.

To learn how to use an impact screwdriver, videos widely presented on the Internet will help.

Impact screwdriver vs impact driver

It is important to remember that an impact screwdriver and an impact driver are not substitutes for each other. The screwdriver also imparts an impact force in a plane perpendicular to the axis of rotation. This, by the way, is its difference from an impact drill, which creates shock loads along the axis of rotation. However, a screwdriver only facilitates the process of unscrewing and tightening an already rotating screw.

These tools perform completely different tasks:

• A rotary impact screwdriver is designed for the initial "break" from the place of the "stuck" screw.
• The impact screwdriver is designed to reduce the necessary pressure on the tool in the process.

After studying the features of impact screwdrivers, it is recommended to watch videos that provide reviews of various models. This will help you make the right choice when buying and become the owner of a useful and reliable tool.
