The most necessary things that every motorist should have are a jack, wires for lighting, a cable and a balloon. Fortunately, now all this can be bought at any auto shop. We are not looking for simple ways and will talk about how to make a homemade jack for a car.
First of all, I would like to draw your attention to the fact that there are several actual designs of jacks. The most popular are hydraulic, rolling and mechanical. Each type has its own advantages and disadvantages.
Mechanical jacks are very reliable, but most models are not designed for heavy loads. Hydraulics lift large masses, but very often oil leaks from under the gaskets at the seals. As for pneumatic, this is one of the best options. Making a homemade car jack is not so difficult, let's see how exactly. Let's start with the simplest. 
One of the most popular types of vehicle lifts is the roll-on type. It is called so not because it can be transported on wheels from one corner of the garage to another. The principle of operation is that while lifting the car, the jack moves under the car. This happens due to the displacement of the lever in relation to the fulcrum.
As a basis for the upper and lower arms, a channel can be taken, as well as a pair of corners. It is worth paying attention to the fact that the jack itself can be hydraulic or pneumatic. The first option is more lifting, the second is less problematic in terms of maintenance. The displacement of the rolling jack is possible if there are two pairs of wheels, and this is the main condition. 
This drawing of a homemade rolling jack shows that in terms of the necessary tool and material, the design is quite expensive. Unless, of course, you have half the material in the garage that is there as junk.
From the material you will need a channel with 4.5 mm walls and 7.5 mm thick shelves. You also need a welding machine and an old bottle hydraulic or conventional pneumatic jack. Do not make the levers too long, 400-500 mm each. But if it was done that way, you should think about making an additional emphasis. The advantage of such a jack is that it is convenient to use. But at the same time, carrying it with you in the trunk is not the best solution. Best used as a stationary "garage" tool.
This is one of the simplest, but at the same time effective designs. For manufacturing, you will need a support platform. Its strength and rigidity should be as high as possible. This can be achieved with the help of additional stiffeners.
An important stage is the supporting structure, which is made of a profiled square tube. It is desirable that its thickness be at least 10 mm. We use an old bottle-type hydraulic jack as a basis. It is worth paying attention that even in this case, you will need a lot of metal profile, welding, as well as effort.
With a responsible approach to work, you will receive a high-quality and reliable design. Nevertheless, it is worth calculating the costs in advance. If the amount is more than 2,000 rubles, then it hardly makes sense to bother with this matter. 
Of course, you can make a homemade car jack. But this is worth doing if this procedure is appropriate. Now there is a huge selection of jacks in stores at an affordable cost. For example, for 1,500 rubles you can get a solid diamond jack. It is reliable, stable and does not take up much space, which makes it easy to transport.
For 2,500-3,000 rubles, good quality rolling jacks are sold. They have good carrying capacity and are reliable, although they are extremely bulky and heavy. You can make a rolling jack with your own hands. But this will require a lot of tools and material, which will ultimately result in serious costs.
A homemade car jack made by you personally will also have its advantages. If you approach the matter competently, then the output will be a reliable design, the resource of which will be clearly higher than the purchased device. But it's easy to make a mistake here. For example, some welds, especially on the bend of the lever, can burst, and this, in turn, will lead to sad consequences. In any case, it's up to you. The drawings presented in this article will help you in making a jack on your own. But it can take a whole day off and a lot of nerves and materials. But if there is a tool, and there is a lot of metal in the garage, then it is definitely worth a try. Especially since you know how to make a jack with your own hands.

The problem of lifting loads of large masses in front of mankind has been standing for a long time. In recent years, jacks have been increasingly used to solve it. The hydraulic jack stands apart in this row. He is able to lift really heavy loads with a minimum of effort. Hydraulics, since the advent of science, has come to the aid of man. There are situations when a lift of this kind is simply necessary, but there is no way to purchase it. How to make a homemade jack?
Scheme of a rolling hydraulic jack.
Of course, before starting work directly, it is imperative to learn more about the design of the hydraulic jack. In fact, it is not so complicated as it might seem at first glance. The main elements are the body, pump, plunger, screw with lifting heel. The hydraulic jack is most often made of hardened steel. In this case, a special oil with high viscosity indicators acts as a working fluid. Conventional motor oil will not work in this situation.
Hydraulic jack device.
It is worth considering this when developing a device. Usually it is the body that is the main part of the hydraulic jack. It serves not only as a reservoir for the working fluid, but also as a real cylinder for the piston. The device of this design implies the presence of protective valves that ensure uninterrupted operation. It is equipped with a hand or foot pump.
The oil is drained using a special handle, which is part of the mechanism. At the same time, the lifting mechanism and a special retractable hydraulic cylinder are able to raise the working platform. A sufficiently high pressure is created, which allows you to lift loads of various masses. The body of such a device can be both short and elongated. The second option is most often used when carrying out repair work on heavy equipment. For example, it can be a bus or a heavy vehicle.

Screw jack device.
There are many options that allow you to use hydraulic jacks everywhere. They are unpretentious in terms of carrying capacity. An important point is the presence of a practically incompressible working material. It's about hydraulic oil. From this we can conclude that smooth running cannot be avoided in the work, that is, raising and lowering. At the same time, the load can be fixed at almost any height. It is worth noting that such devices have a fairly high efficiency, which is equal to 80%. At the same time, the lifting capacity of the mechanism can reach 200 tons. Of course, such powerful aggregates will not be considered in this paper, but the reader should be aware that they exist.
It is necessary to note the initial height of the rise. This indicator is better than that of ordinary mechanical models. Loads can be lifted from almost zero height. This is very convenient, especially when it comes to repair work with low-slung cars.
The device is a simple homemade jack.
There are, of course, disadvantages to hydraulic jacks. The main one is that it is very difficult to adjust the lowering height in such mechanisms. In order for the device to be constantly in working condition, it has to be checked. Here it is necessary to monitor the oil level, the condition of the valves, gaskets and seals. If necessary, these elements must be replaced. Sometimes it can be difficult to transport jacks. They must be stored and transported only in an upright position.
Otherwise, it is likely that all the liquid from the tank will simply leak out. Another disadvantage is the relatively large mass of the device. It is not always easy to transport it from place to place. The cost also makes many think about alternative solutions to the problem. Some people buy mechanical jacks because they are several times cheaper, while others make their own hydraulic jacks.

Hydraulic press device.
The hydraulic jack itself is not that interesting, since it is quite simple, but the press can be useful for every person who loves cars. It will serve as a real garage helper. With it, you can press bushings, punch holes in various metal blanks. A hydraulic jack will be used to create pressure in the structure. To work, you will need a grinder, a welding machine with a certain number of electrodes and an angle grinder.
The first node in this design will be the support platform for the jack. Since you will have to work with quite impressive weights, you need to make the platform as reliable and powerful as possible. Do not forget about this nuance. It is quite difficult to achieve the desired result. To do this, you need to apply several stiffeners at once. Only in this way will the design be truly of the highest quality and reliable.
For work, you can use both a square and a rectangular profile.
Drawing pneumohydraulic rolling jack.
Here the choice depends directly on the capabilities of a person and on what he has at hand. Further, these parts of the structure are laid base to each other. In this case, it is worth making as many welds as possible. This will achieve the required rigidity. You need to weld the elements to each other both from below and from above. In order for the design to be stable, it is necessary to additionally use a metal plate for the stand, the thickness of which will be at least 10 mm.
Next, you need to make emphasis and racks. To do this, you first need to prepare a profiled pipe, the cross section of which will be square or round. To calculate the height, you will have to add several values \u200b\u200btogether. It is necessary to add to the height of the jack the value of the working stroke of the rod, as well as the height of the platform. The resulting number will be the result.
The emphasis must be made of the same metal from which the racks are made. Then all the elements are connected to each other. The result is a U-shaped design. In order to ensure the perpendicularity of all structural elements, it is necessary to make a very simple fixture. On a steel plate, the thickness of which will be at least 10 mm, it is worth laying two corners at an angle of 90 °. Then all these elements are welded together. Everything is quite simple, but at the same time the design turns out to be really as reliable as possible.
The load capacity of the screw jack is calculated by the formula.
In order to further make it more convenient to work, this device should be equipped with special clamping mechanisms. This will fix the resulting triangle and avoid further displacement along the axes.
The next stage of work is the creation of a special stop that will move along the guides, transferring pressure from the hydraulic jack directly to the workpiece. To work, you will need to use a special metal piece. Its thickness should not be less than 1 cm. The length of this part should be slightly less than the distance between the uprights.
It should be noted that the components of the stop are interconnected by welding. In this case, you should not save on electrodes. Only a good connection of all structural elements will make it possible to make a really high-quality design. Now you can proceed to the installation of the hydraulic jack itself. It is fastened with two bolts of the same length.
It is worth making it as strong and rigid as possible. If during the execution of work it is necessary to reduce the working stroke of the hydraulic jack rod, then it will be necessary to make the distance between the stop and the steel part of the structure, that is, its beam, smaller. For this, an additional metal plate of the corresponding profile is used.
In order to make this distance less impressive, you can use additional removable inserts. They should be additionally marked in order to make the fastest possible tool change during the work.

So, the above revealed the advantages of hydraulic jacks. As you know, this device can be used not only for its intended purpose. For a garage-type press, it is quite appropriate. A hydraulic jack in this case becomes one of the best options for creating such a press. Of course, this is not the only such case of non-standard use of a hydraulic jack in practice. The hydraulic jack itself is extremely simple to make.
Knowing the design of this device, you can experiment with its designs. This is a great solution for every car enthusiast. The hydraulic body is made of hardened steel. Do not forget about high-quality materials for the piston itself. He will have to transfer the maximum load. Only hydraulic oil should be used as the working fluid. It has high viscosity.
Only such oil is capable of creating high pressure in the working mechanism. Knowledge will allow everyone to make a hydraulic jack and a press with their own hands.

Making a homemade comfortable car jack from improvised materials is very simple! in the video a short overview, if you are interested in something about this invention, ask questions. and offers!
A jack is a device that should be located both in the trunk of a car and in the garage of a car enthusiast. At the same time, it is better to choose the second option more massive with universal functionality and a high load capacity. These characteristics are 100% do-it-yourself, which will not be difficult to do.
There are three main criteria by which a homemade inflatable jack is evaluated:
Definitely, when choosing a jack and its manufacture, first of all, you need to focus on your car, the conditions for its operation and storage.
To build a jack with your own hands, you will not need much material and effort. You need to select the following items:
The structure is assembled from the presented elements. A bolt is screwed into the hole in the pillow. First you need to make a socket for the fitting from the camera.
A wheel bolt from a VAZ is used as a valve, in which a hole is drilled. At the next stage, the existing elements are connected after a ball is installed in the hole, which will serve as an air intake.
For the practical implementation of this device, a special pump is required. The inflatable jack is installed under the bottom of the vehicle. For safety, it is advisable to use a wooden stand that will interact directly with the machine.
This mechanism has one significant drawback. Since the cargo cushion has a decent size, a low-slung car will have to be raised beforehand to install the device in question. If you attach a cart with wheels to the bottom of such units, you will get home-made ones for cars.
The pneumatic version lifts the load due to the compression force of the air mass. Such modifications work from connection to additional equipment or from the exhaust of the machine. The air mass enters the chamber. Due to compression and increase in volume, the car rises. The advantage of the models is that you do not need to make special efforts, and in the presence of a compressor unit, the process takes a matter of seconds.
A mechanical jack for a car involves bringing it into operation by rotating or twisting a special handle. Such modifications have a low price and compact size.
The principle of hydraulics is similar to the mechanical version. The difference lies in facilitating the process of pumping out the working part of the jack, due to the presence of liquid in the working system. Such modifications have a long service life.
A mechanical jack with an electric drive is powered by mains power, all the main work of the device is performed by electricity. The advantages of the device are undeniable, but you need to connect it to the outlet.
Despite the fact that the inflatable jack is one of the most elementary in terms of operation, its use requires certain precautions.
To prevent the unit from flying out from under the car, it must be installed correctly. Before installing a new pneumatic device, it is advisable to deflate it once without load, after which it descends and fits itself accordingly. To protect the jack from damage, it is better to lay a rug on the floor.
For the manufacture of the working chamber of the device, materials based on PVC are suitable. At sub-zero temperatures, this design hardens and becomes rough. According to experts, the optimum operating temperature is up to -10 degrees.
It is quite possible to make a hydraulic jack with your own hands. It is based on a body, the main bearing function is performed by a retractable piston and a working fluid (oil). Variations of the fixture can be made with a shortened or elongated steel frame. The housing is a reservoir for oil and a guide cylinder for the piston.
A special adjusting screw with a lifting heel is screwed into the plunger, if necessary, you can increase the maximum lifting height. Such a device is equipped with a manual, foot or air type drive.
The working mechanism and the retractable cylinder are located in the holes of the frame. The unit is lowered by turning the T-handle. Some devices are equipped with polyamide wheels that provide maneuverability. Operational safety is ensured by safety valves.
Before you make a jack with your own hands, you should consider all its pros and cons. The advantages of a hydraulic device include the following indicators:
The disadvantages of using the hydraulic model include a high initial lifting height, the problem of the accuracy of lowering position control, a decent price and a rather large weight. Store and transport the device only vertically, otherwise the working fluid may leak out.
Making a jack with your own hands will not be a particular problem. Depending on the possibilities, the scope of use and other objective circumstances, you should choose the right model for the type of work. For use on the road, a compact device of a mechanical or hydraulic type is suitable, and in the garage an inexpensive and practical pneumatic device will work perfectly.
Having at hand a drawing - a screw jack, we make it with our own hands from steel bent equal-shelf channels GOST8278-83.
In the figure, the types of sizes of the assortment used are highlighted in blue rectangles
The screw jack consists of the following parts:
Base
Lower shoulder
upper shoulder
Emphasis
screw mechanism
BASE
Let's make from a range with a cross-sectional area of \u200b\u200b2.63 (cm²). We drill four through holes with a diameter equal to the diameter of the pin. When drilling, strictly maintain the center distance between them. If necessary, the base can be attached to a wider removable platform.
LOWER SHOULDER
We will produce from a range with a cross-sectional area of \u200b\u200b1.99 (cm²) by analogy with the base.
UPPER SHOULDER
Let's make from a range with a cross-sectional area of \u200b\u200b2.28 (cm²) by analogy with the lower shoulder.
UPOR
Let's make from a range with a cross-sectional area of \u200b\u200b1.99 (cm²) by analogy with the upper shoulder.
From above, we fasten the rubber gasket.
SCREW MECHANISM
1. Shaft - screw. We will make from a metal bar with a diameter of twelve millimeters. On the one hand, there is an M12 thread, on the other, a retainer, which is attached to the shaft with a cotter pin through a through hole on the shaft.
2. Axis - emphasis. Relative to which the rotation of the lower and upper arms occurs.
The axles on both sides are pins with cylindrical flat heads, which are attached to the axle with cotter pins.
A through hole with a diameter of ten millimeters was drilled in one stop, and an M12 internal thread was cut in the other.
3. Retainer. Fixes the shaft from the side of its rotation and provides the possibility of transmitting torque to the shaft.
Performance characteristics of a do-it-yourself screw jack.
Almost everyone has a car now. For some, it acts as a source of income - these are taxis, buses, cargo transportation, etc. Some people need it just to get around. But for true motorists, the car is the closest friend who helps out in difficult times and never fails. They take care of it, take care of it, repair it on time. Often such people in life are friends with technology and love the instrument. They like to do something with their own hands, because it brings great pleasure. Often you get some useful and interesting gizmos for the car.
For example, it would be a good idea to make a jack. Indeed, not a single motorist can do without this device. Many, of course, will now say that it is easier to go and buy it in a store. But for a true mechanic to build such a thing, especially for his car, it will not be difficult. It is only important to know how to make a jack, and what it will consist of.
Before you start making a jack for a car with your own hands, you need to decide what design it will be. To do this, you need to know the main varieties of these devices that can be found in stores:
rack jack
screw jack
Hydraulic jack
pneumatic jack
These are the main types of jacks that are used most often. They are classified precisely according to the type of force used (mechanical, hydraulic, etc.), but there are many varieties of them. So, for example, hydraulic devices are haulage, cylindrical, trailed, two-level. That is, there is one type of jack, and there are several types of it. Therefore, there is a great choice in order to independently make your own model using a prototype.
It should be said right away that needlework is not an easy task and requires certain skills. In our case, these are almost all the abilities that a novice mechanic should have:
If you have the above skills, then in the process of making a jack, no problems should arise. The higher the skill level of the tool, the better the product will turn out.
In order to make a jack, you must have the right tool. The first step is welding, since it will be assembled with its help. It is desirable that this be semi-automatic apparatus with carbon dioxide. Then the seams will be much smoother and there will be no excess slag. Second, and no less important, is Bulgarian. Well, if the assortment has both small and large. With their help, you will cut blanks from steel. You will also need drill, because you have to make more than one hole. In order to easily process iron parts, it is necessary electric sharpener. It is key in the fitting process. In addition, it is desirable to have hand tools: files, needle files, bars, hammers, screwdrivers, rasps, lehrs with a set of taps, sledgehammers, vise, etc. The more tools at hand, the easier the manufacturing process will seem.
The more tools available, the easier and better the jack will turn out.
Lathe in any business is an excellent assistant, but not everyone has it. In principle, you can cope without it, but if you have such a unit in your garage or workshop, it will turn out much faster. After all, with the help of a milling machine, it is easy to carve or process any part. For example, a bolt or a rod. In general, your machine will be very handy.
It is also worth talking about the material. It can be bought at the market or at the scrap metal collection point. The second option is much cheaper, since all the metal is rusty and battered at scrap receptions. It is not suitable for operation, but as a donor, that's it. It is desirable, of course, to buy more of everything. Indeed, depending on what kind of jack you want, you may need additional mechanisms or fasteners that you cannot make yourself. Therefore, be prepared to purchase some components on the market.
The base (both the lifting arm and the lifting platform) of the hydraulic jack can be made from a channel. For lifting force, a conventional hydraulic bottle jack is used. To move the jack, you can attach wheels (can be replaced with bearings, rollers or something similar).
The device of a homemade hydraulic rolling jack
It is recommended to install a bottle jack on a movable “swing” platform, since during operation the jack slightly changes its angle, and some movement compensation is required. The platform should sway slightly from side to side. You can make it from the same channel by drilling a through hole in the lifting base and putting the "swing" on the bolt so that there is a small gap of 0.5-1 cm between the base and the platform.
Movable platform for bottle jack
To increase the strength of the structure, it is desirable to make braces of rods on both sides of the base. The thicker the rods, the better. They are welded to the base.
The device is powered by a bottle jack. When it is set in motion with a special rod handle, it rises, which moves the lifting lever up.
The process of operation of a homemade hydraulic rolling jack
A drawing of such a hydraulic jack for making it yourself is shown in the image below:

See also a few video where you can learn more about how to make a hydraulic jack with your own hands:
As an example, consider also a pneumatic device that easiest to do. So, you will need:
In principle, with such a home-made device, any car can already be easily lifted. It is enough to substitute the pneumatic cylinder under the platform on the bottom and connect the high pressure hose to the fitting. By supplying compressed air, the pillow will begin to rise with the machine.
The principle of operation of a homemade pneumatic jack
For convenience, such a jack can be completed by inventing a reliable platform with wheels for it. Thus, if the cylinder is taken for disassembly, then a home-made device comes out almost for a penny.
Improved air jack on wheels
You can also see some video how to make a pneumatic jack with your own hands:
The most important question remains. Is it worth it to make a jack yourself? The answers to it may be different, however, after weighing all the nuances, you can come to the final conclusion. To begin with, it is worth understanding the cost. It is clear that no one will buy a tool for manufacturing, however, you will need material and some parts that you still have to purchase. It is quite possible to buy a new factory jack for 5,000 rubles. Waste on homemade will depend on what kind and type it is. So, making a hydraulic one will be the most expensive, but the pneumatic one discussed above is the cheapest.
In general, the cost of a jack is not so big to rack your brains and make it yourself. If you don't care, then it's better not to take it on and buy a new one in the store. But, if the process itself is interesting, and you want to make something, then this is a great idea to test your skills. You may even be able to save 1-2 thousand rubles. That is, when there is a desire to do - try, be wiser and achieve results. But if the process of making a jack is not interesting to you, then it is better to postpone this matter.
The main thing to remember is safety measures. Any tool in inexperienced hands can cause serious injury. Remember to also wear protective goggles when working with metal and when welding to protect your eyes.
