DIY impact screwdriver from starter

Hello to all DIY lovers. In this article, I will talk about how to make an impact screwdriver that will help you unscrew rusted or soured fasteners, for example, a bolt in an aluminum case. All the parts that are needed to assemble this homemade product are easily accessible, especially if you are the owner of a car.

Before you start reading the article, I suggest watching a video that shows the entire assembly process followed by testing the finished impact screwdriver.

In order to make an impact screwdriver from a starter with your own hands, you will need: An angle grinder, a cutting wheel, safety glasses, gloves A mechanic's vice A faulty car starter An old square wrench A metal pipe with a diameter equal to the diameter of the bendix A metal lathe, a through cutter A pair of small springs Metal washer Welding machine, welding helmet, leggings Drilling machine, metal drill with a diameter of 5 mm Tap with M6 thread Core M6 bolt Boring cutter Small hammer Masking tape Can of hammer paint

Step one. The first step is to disassemble the faulty starter from the car, only two parts will be needed from it, this is the armature of the electric motor and the bendix, on which the principle of unscrewing will be based. You can purchase a non-working starter at a metal acceptance shop, for which they will ask for pennies compared to buying a factory-made version of an impact screwdriver.

Step two. Now you need a part with splines from the Bendix; it can be sawed off using an angle grinder with a cutting disc installed, and then refined on a lathe to the desired size. When working with an angle grinder, be careful, you must hold the power tool firmly in your hands, and also do not forget about protective glasses and gloves. The splined part will subsequently be put on the shaft and transfer rotation to it from the impact.

Step three. In order to be able to install various heads on this screwdriver, you need to cut off the tetrahedral part from the driver using an angle grinder.

DIY impact screwdriver from an old drill

An impact driver is used to loosen tightly welded bolts and screws. This useful hand tool can be purchased at any hardware store. But if you like to do everything yourself, then you can make such an impact screwdriver yourself from scrap materials.

The principle of operation of an impact screwdriver is very simple: the impact force is converted into torque, as a result of which you can easily unscrew even the most “stubborn” bolts and screws that cannot be removed by a regular screwdriver.

In this case, the master uses as a basis an old drill with a diameter of 16 mm, which is ideal for this homemade product. Also for this homemade product you will need a piece of pipe with a diameter of ½ inch, two balls from the bearing, a spring and an M16 bolt.

Main stages of work

First of all, you will need to cut a piece of half-inch pipe 170 mm long. Next, stepping back 15 mm from the edge of the pipe, you need to drill a through hole with a drill with a diameter of 10 mm. The craftsman inserts two balls from the bearing into the drilled holes.

To prevent the balls from falling out of the “seat,” you need to put a ¾ piece of pipe 20 mm long on a half-inch pipe (that is, you get a kind of fixing ring).

To put the ring on the pipe, you will first need to make a cut in it with a grinder along the weld. You also need to drill two holes on the sides.

At the last stage, a square is cut out in the drill shank for the socket heads, after which you can begin the final assembly of the device.

You can watch the video on the website for details on how to make an impact screwdriver from an old drill with your own hands.

Useful tips

Quite often there is a need to unscrew heavily rusted fasteners. What to do in 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. A good solution for this is to use an impact screwdriver. Thanks to it, unscrewing rusted parts will not be difficult. It is enough to wet the fasteners with brake fluid so that when dismantling the part can be unscrewed as easily as possible.

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

Specifications

When reviewing these characteristics, it is not necessary to talk about the build quality and reliability of the material from which the tool is made. Trusted companies never use low-quality steel to produce such products.

You should pay attention to the presence of a reverse, which significantly expands the basic capabilities of the device, allowing you not only to unscrew rusty connections, but also to firmly tighten the screw in the place where it is needed.

The next important factor is the design of the handle, which is intended to hold the device and the body. If there is a polyurethane, rubber or polyethylene lining on the body, it is much more convenient to hold the screwdriver. If the pad has a “bulge” in the heel part, this has a positive effect on operational safety. In most cases, screwdriver manufacturers follow two paths:

The dimensions of the case do not change, while the screwdriver remains highly reliable, but cannot be used in extreme and cramped conditions.
To expand the scope of application and improve ease of use, the dimensions of the metal case are reduced, although the reliability of the tool suffers because of this. When choosing the ideal solution, you should carefully weigh all the features and only then make a purchase.

It is no secret that popular brands produce screwdrivers along with an additional set of attachments, because without these elements the tool is simply ineffective. The screwdriver comes with a holder for standard bits, and the kit also includes several universal bits.

The market for such products is overflowing with attachments for various splines and hexagons. When purchasing these parts, be careful and consider the build quality. This is a very important parameter that determines the reliability of operation and service life of the screwdriver.

How else can you treat the device?

Use gasoline or kerosene, diesel fuel.
An acid with low aggressiveness. Vinegar will do
Coca-Cola helps break down scale in the kettle. Why not try using a drink to neutralize rust.

These substances have high penetrating characteristics. Coca-Cola contains phosphoric acid, which is credited with cleansing properties. If possible, the part with stuck hardware is completely buried in one of the listed liquids. Although in some cases it is enough to wrap the bolt head moistened with liquid. The waiting time before further work with an impact screwdriver is a day.

As you understand, the option of unscrewing a rusted bolt with acid is not as safe as in the case of Coca-Cola. If the fastener is located next to a soft material, for example, near a rubber gasket, you should avoid acid.

How to work with acid correctly? First of all, wear gloves. Secondly, build a rim from plasticine or wax around the circumference of the cap. Drop a little acid into the resulting cup and put a piece of zinc. 12-14 hours - and the rusty bolt will come off. You can increase the penetrating and cleaning properties by simultaneously heating the surface to be treated. An industrial hair dryer or blowtorch is suitable for this. But be careful - you can only use a blowtorch when pouring Coca-Cola. Sulfuric acid must not be used!

Advantages and disadvantages of the tool

Like any tool, such a screwdriver has its advantages and disadvantages. Working with it, experts note a number of key advantages:

Effective distribution of impact energy.
Much less need for physical effort. The classic version requires stronger and more intense blows.
Possibility of operation without the help of a partner.

As for the disadvantages, they are practically absent, however, if the basic rules are not followed during operation, such disadvantages often appear:

Possibility of damage to the impact-rotating unit. The version of the simplest impact screwdriver is made of a monolithic structure, so its service life exceeds the modernized solution. To prevent unexpected damage, it is enough to avoid too strong impacts on the impact-rotating mechanism.
Tendency to wear out quickly. Gear teeth and races are very exposed to friction associated with shock loads. With prolonged use, their service life deteriorates significantly.

Using the tool at work

Before starting work, you need to clean the screw head as much as possible and especially the slot into which the working attachment is inserted. To do this, you can use a brush with metal bristles. Then apply a drop of brake fluid to the head to wet out the rust. You can also use:

universal aerosol lubricant WD-40 or any equivalent;
antifreeze;
kerosene;
any machine oil.

After applying to the joint, you need to give the lubricant a little time so that it penetrates into the loose structure of the rust.

Next, you should select the desired attachment for the tool, trying it on the slot. As a rule, the kit of such equipment includes the necessary set of various bits and attachments. It is important to correctly insert the desired nozzle into the head of the rotating mechanism - screw the cartridge with the nozzle into the slot as tightly as possible. Now you need to make several light blows with a hammer on the heel of the striker, while holding the power screwdriver so that its axis coincides with the axis of the fastener being unscrewed.

If the screw moves out of place, switch the device to reverse rotation and again make a few gentle blows. You can repeat this operation several times, periodically adding a little lubricant to loosen new layers of rust. Then you can use a screwdriver or hand tool to completely unscrew the hardware.

Unfortunately, even such a breaker screwdriver does not always help. The mating parts are sometimes so affected by corrosion that when you try to unscrew the screw or screw, it simply bursts. In this case, the only way to remove it is drilling.

DIY impact screwdriver from starter

To create this simple tool at home, you can use a faulty electric starter from a car, 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 remaining part so that only the shaft and bushing remain, which we will use as the main mechanism.

We can use a small piece of pipe as a handle, into which we must place a sleeve on one side. And on the other we need to insert a plug, which will also serve as a striking 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 bushing.

The next step is welding all the parts.

Finally, the end of the shaft must be sharpened square for possible change of different attachments. So, to unscrew a screw or nut, it will be enough to insert the necessary bit and dismantle the fastener. If you need to unscrew a screw, you must insert the appropriate bit into the head.

It is worth noting that the electric starter is made of high-quality steel, so you will have to use a grinder to cut it. But thanks to its strength and carbide, 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, you should use it carefully, without applying strong blows, so as not to tear off the heads of 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 be in no way inferior to its factory counterpart.

Step-by-step instructions for making an impact screwdriver

To make a home tool with your own hands, you need to stock up on a starter from a car. Perhaps the part was lying around in the garage. We begin to transform the starter into an impact screwdriver useful for the home, focusing on the drawings and diagrams presented below. Follow this guide:

Separate the part of the rotor shaft where the winding is fixed.
In the part that remains, remove unnecessary components. The shaft and bushing should remain. They act as a single mechanism.
The handle is made from a pipe. A sleeve is placed in the pipe, but only at one end. A plug is placed on the other side. She will become the striking heel. A large bolt is suitable for the plug. It prevents the tube from changing during impacts and limits the shaft from sliding on the inner surface of the bushing.
Next, weld the parts together.
At the end of the shaft, build a square-shaped sharpening. This seemingly insignificant detail will allow you to change one attachment to another. If you plan to unscrew the fastener, a bit is secured in the head. A different tip is required for dismantling.
When starting to cut the starter, arm yourself with a grinder. Other equipment with low power will not accept high-quality steel.

To extend the life of a homemade device, regularly apply an even layer of lubricant to the splines. Be careful when using the device. Strong blows to the heads with a hammer can damage the instrument.

A visual video instruction for making an impact screwdriver with your own hands is shown below:

Principle of operation

According to 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 rotates on the bottom of the screwdriver. This rotating force is quite enough to dismantle strong fasteners.

To simplify the work process, you can pre-lubricate the fasteners with brake fluid. After this, you need to install the tool at a right angle to the head of the hardware and use a hammer to strike the end of the screwdriver. After noticeable rotation of the fasteners, you can continue unscrewing using a regular screwdriver.

How does an impact screwdriver work?

The impact device has a built-in rotating mechanism that turns the impact on the tool into rotation. Installation and dismantling of threads of any configuration and fragile parts becomes simple and straightforward. The impact device is indispensable. A regular screwdriver will not budge an outdated bolt and will eventually break. It is not a fact that the fasteners will not deteriorate.

To make the fastener easier to manipulate when working with an impact tool, the product is lubricated with brake fluid on top. Leave the part for half an hour. During this time, the fastener will properly absorb the liquid. Next, do the following:

Place the screwdriver at a right angle to the head of the device.
Hit the end of the tool with a special hammer.
The fastener should turn a little.
Try it - maybe now you will be able to unscrew it with a regular screwdriver. If not, continue unscrewing with impact.

Advantages of a homemade tool

The screwdriver is equipped with a reinforced body made of high-strength steel.
It is larger in size compared to factory screwdrivers;
Operation of the tool is safe for humans when struck correctly with a hammer. If you follow the safety rules, it is impossible to get injured with a screwdriver;
There is the possibility of changing attachments, based on the type of work being carried out;
Easily made at home without significant physical and financial costs;
Multifunctionality. Can be used for various tasks in the field of construction, automotive, and any other craft.

DIY impact screwdriver: how to make a tool from a starter

An impact screwdriver is a fairly popular tool that is used not only by professional builders, but also by amateur craftsmen for home projects. It is indispensable for unscrewing tightly “welded” screws.

Regular screwdrivers are useless in such cases, but impact screwdrivers allow you to combine the force of a hammer and torque in one tool. So how can you make your own impact driver using a car starter?

According to its operating principle, an impact screwdriver is similar to a bolt. During the work, the mechanic has to hold the handle of the screwdriver with one hand, while with the other he hits its end with a hammer.

What is an impact screwdriver

There are practically no visual similarities between an impact screwdriver and a standard one. This tool is a rotating impact mechanism that allows you to convert impact force into torque. It is used to install and dismantle threaded connections that require additional effort. Using a regular screwdriver for these purposes will lead to breakage of the tool or damage to the element being dismantled.

Useful tips

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

Conclusion

DIY impact screwdriver

Having such a homemade screwdriver, you can easily pull out a bolt with severe corrosion. It is an indispensable tool in dacha farming.

There are times when you need to unscrew a screw whose edges have been torn off, or a bolt that is fairly covered with rust.

An ordinary tool will be of little help here, but an impact screwdriver will be very effective, for the manufacture of which I used the rotor of a faulty electric starter from Zaporozhets.

I cut off the winding part of the rotor shaft and removed the excess from the remaining part.

After that, only the shaft and bushing remained.

A piece of pipe was placed on the sleeve, which acted as a handle. At the opposite end, a plug from a large-sized bolt was inserted into the tube. Due to this, the handle cannot be deformed when struck by a hammer, while at the same time the stroke of the shaft in the sleeve is limited.

Electric welding was used to connect all the elements of the handle.

At the end, the shaft is sharpened into a square - now you can put a head on it for bolts. Need to remove a screw? We take the appropriate version of the bit and install it in the head. When you hit the end of the handle with a hammer, the shaft on the oblique splines rotates slightly in the handle - this is enough for the bolt to break out of place.

Since high-quality hardened steel, which is cut with a grinder, was initially used for the production of electric starter elements, we received a screwdriver with high strength, hardness, and a long service life. In order for the work to be effective, you should not hit the handle too hard with a hammer, as the heads of the bolts and screws will break off. You also need to ensure that the splines are lubricated at all times. It should be noted that a starter from almost any car is suitable for this homemade product. A larger tool will be more powerful and efficient.

Impact screwdrivers: types, characteristics and manufacture

In the process of carrying out plumbing work, each person may encounter a problem in the form of rusted fasteners. You can try to unscrew them using a regular screwdriver, but this may not always work. There is a possibility of tearing off the splines or, worst of all, damaging the tip of the tool.

The most difficult job involves removing steel bolts from metal bases. Rust is a strong connector between these two elements, making it extremely difficult to separate them. But with an impact screwdriver, this problem turns into a small nuisance that anyone can handle.
