It will find its application in any private house or garage workshop.

Such equipment allows you to cut parts made of metal, wood, polystyrene and a number of other materials, drill holes, cut threads, and process ends.

Anything that involves changing the shape or surface of a part is done on a lathe. These works are possible both at home and in a specially equipped office.

It is not surprising that the first, most primitive prototypes were made in Ancient egypt, a stone was turned on them.

In museums, there are turning and milling mechanisms for metal of the 14-15th centuries, rotation in them was due to the foot pedal.

The rapid development of industry at the end of the Middle Ages required a qualitative breakthrough in equipment - the manual mechanism was modernized, and the first turning and milling machine for metal, powered by electricity.

A little later, equipment with numerical control (CNC) was created.

The modernization of production required more and more highly specialized tools, and equipment with CNC began to be created not only for working with wood or metal, but also performing very narrow operations, for example, edging door leaf or drilling cavities for the lock insert.

In this form, they are used to this day.

In this article, we will conduct an overview of existing equipment and look at how to make a simple machine with your own hands, and how do-it-yourself upgrades can improve equipment.

Industrial equipment is divided into light machines, weighing up to 1 ton, medium in weight - up to 10 tons, and heavy - over 11 tons.

Each machine performs one or more operations for processing wood or metal at home or in production.

All modern turning equipment is equipped with CNC, from the simplest to the most complex, which controls the turning of the part with an accuracy of tenths of a millimeter.

The modernization of machine tools has divided equipment into heavy and bulky, performing tasks for heavy industry, as well as miniature high-precision, producing tiny parts. precision instruments Are desktop CNC machines.

Regardless of the size and purpose of use, lathes have the same basic components and assemblies.

It consists of a base on which the bed is installed, along which the caliper moves along the guides.

At opposite ends of the equipment, there is a headstock that transmits rotation through the spindle of the workpiece, and a tailstock that moves freely and is fixed depending on the size of the workpiece.

The CNC is connected both to the motor (at the required moment it stops rotation) and to the cutting element itself.

A close relative in terms of the principle of operation is a milling machine. It is also used for wood and metal.

The milling mechanism, due to the cutter installed in the spindle, makes a rotational movement, and the translational movement of the part feed can be either rectilinear or at an angle, depending on the task.

Usually the milling mechanism is equipped with a CNC. Highly wide application has a center that simultaneously performs milling and turning work.

DIY equipment

There are many options for how you can create a homemade lathe.

If you often have to do the same job, then table turning mechanisms in the workshop of your home will be of great help.

Most often, for a working piece of equipment, a drill is used, which is reinforced on the base. With the initial skills in working with electronics, it is realistic to even come up with a CNC machine.

The base or frame of the turning equipment can be made from metal corners or wooden beams.

Table turning mechanisms can have a base in the form of a strong chipboard.

If you are faced with the task of short-term processing of small parts, then it is quite possible to use a motor powered by a 220V network.

The frame design must ensure that the following conditions are met:

• both the leading and the driven center are located on one straight line, which is parallel to the axis of rotation;
• the center of symmetry of the part coincides with the axis of its rotation;
• the part is securely fixed on the headstock.

You can turn a part that rotates between the headstock and tailstock using any tool - files, file files and others.

Homemade table lathes are designed for side machining of parts. For example, it will be convenient for them to handle the baluster of a wooden staircase.

With your own hands, it is easy to create not only desktop, but also full-fledged lathes.

The main thing that will distinguish tabletop options from a full-size machine is the engine.

The larger the homemade machine, the more bulky parts it can handle.

And to work with large workpieces, of course, you need a powerful engine.

Lathe from engine

Consider a homemade machine made with our own hands from the engine and power supply unit of an old Soviet tape recorder.

Its basis will be wooden plank, from its pieces, cut in the form of squares, the side of which is equal to the width of the base of our future machine, we will form tailstock.

We will form a casing from the metal, in which we will cut out a hole for the output of the rotating mechanism. We will fix the engine on the casing.

Now you need to find the projection of the center of rotation on the tailstock.

To do this, you can make a cylinder out of paper that clearly corresponds to the distance between the headstock, fix it on the headstock and use the drive to wrap it around the axis several times.

If the cylinder rotates smoothly, then the fixing point of the part will be the center of the circle that describes the cylinder on the tailstock.

We put a self-tapping screw or any other holder for the workpiece into the center. Of course, this work is done by eye and does not imply high precision turning work.

The modernization, which will increase the accuracy, if the distance between the headstock is more than 20 cm, is possible if the workpiece clamping center is brought out level by placing it between the engine head and the tailstock.

We made the simplest mechanism with our own hands.

It can handle the lateral surface of a long piece of cylindrical and conical shape, as well as a simple bar.

Given the low power of the machine, it is applicable only to wood parts. In the same way, you can make a milling mechanism with your own hands.

Lathe with a drill

Modernizing the idea of ​​finding affordable electrical appliance, producing rotation, will tell you to use a drill for a do-it-yourself turning mechanism.

It is found in every home. Often, and more than one, because it is usually purchased inexpensive option, and then it turns out that it is weak in power.

For a turning mechanism, you will need a drill, any base (a piece of plywood, board or plate), a wooden skewer on which the workpiece will be put on, and a wooden square for the tailstock.

We fix the drill in any way, at the marked length we fix the tailstock made of wood, insert the rod into the drill and drill a hole in the headstock.

The skewer and the workpiece rotate, and the person with the help sandpaper processes the workpiece.

An upgrade of such a mechanism can be carried out, during which any processing device (for example, a file), which will be a manual analogue of a CNC, will be attached to the base.

So, if we need to make a tapered depression around wooden parts, we can make the following improvements - take two flat files, fix them so that they touch the part, and a trapezoid is formed between the surface of the part and the base with the files.

Now we need to ensure, using a simple spring mechanism, the files are fed evenly forward and at an angle.

Mechanism improvement options:

• Modernization for metal work can be done by replacing the skewer with a healing mechanism. Attach a spring clip with a plate to the metal rod, install one such rod in the drill, and the second in the tailstock. A metal workpiece will rotate between the plates, and we will be able to perform turning work on metal;
• Long workpieces are often required at home. You can make a collapsible drill fastener, an easy modernization of the base of the mechanism will allow it to be rearranged to handle longer objects;
• Equipment upgrades can be carried out by taking a more powerful engine (for example, from washing machine) and make the base larger. There is no direct relationship between the area of ​​the base and the power of the engine, but it must be taken into account that oscillations occur during the operation of the engine, and the base of the machine serves as a support, thanks to which the equipment itself with the rotating part will be in an equilibrium position.

We looked at how easy it is to do homemade mechanism for turning work from parts, which you probably have at home.

Upgrading the simplest equipment for your specific tasks will help you handle items in a more complex way.

To create a home of a full-fledged CNC lathe, you need a control unit, however, it is difficult to make it without special knowledge.

As we have demonstrated, the manual analogue of CNC can be simple tools for processing wood or metal, fixed to the base at the right angle.

The dream of every DIYer, modeller and home master - lathe... Everyone who managed to complete the privatization of socialist property today has huge bonuses in the form of lathes, drilling and other means of small mechanization in their garages and workshops. Who could not - have to make machines with their own hands, since the minimum cost of a small mediocre Chinese turning device corresponds to the annual salary of our non-deputy. There is only one way out - to do it yourself, which we will now do.

Table lathe, main units

A mini lathe for metal with your own hands is performed on the basis of what was done in production conditions, but for one reason or another, it no longer serves its intended purpose. This means that the main components and assemblies will have to be taken from other devices that are completely unsuitable for this, adapt them and use all your ingenuity.

So, the main parts of a screw-cutting or turning-milling machine should be:

Actually, these are only the main parts that have to be made or picked up from what is at hand.

Parameters, advantages and disadvantages

The main parameters of a do-it-yourself lathe are linear dimensions, power and processing accuracy. We are not talking about a specific device now, since everyone sets tasks independently, and in the drawings and diagrams presented on the page, you can find a suitable option for yourself. We are talking about the idea of ​​creating a tool in principle and its main parameters.

So, depending on how far from the guides the center of the spindle and tailstock will be located, the diameter of the workpiece will be determined. The length of the workpiece actually depends on the degree of freedom of movement of the tailstock along the guides. The same is with the feeding device, which must correspond to the dimensions of the maximum diameter of the workpiece.

But you need to be prepared for the fact that a homemade lathe will not be able to provide high processing accuracy and high speed. It will be a device for making parts with a low accuracy class. What it depends on, let's figure it out further.

Processing on lathes, diagrams and drawings

Briefly about the control system, we can say that if knowledge and skills in engineering radio modeling allow, you can always make the simplest screw-cutting lathe or with numerical control. Lathes with CNC allow you to automate the same type of work and they are needed if the master has to do a large number of identical blanks according to the template.

In the bulk, bench-top machines are designed to perform one-time work, so the use of complex programming systems is hardly justified on machines with a low degree of accuracy.

The accuracy and performance of a homemade device

In the event that the task is to create a machine tool for metal cutting with a high degree of accuracy, you need Special attention to give guides and bed. Many perform structural elements made of wood, it's fun budget solution, but it will not provide the required accuracy simply because the material of the bed and rails must be harder than the workpiece.

Therefore, all beds and guides for metal lathes are made only of metal. It is advisable to use factory guides, but if this is not possible, which happens most often, then you have to use rolled metal, as in the example that we cited from the ancient English magazine. That is, all the details that are responsible for accuracy and strength must be made in production conditions, such as this option, where automobile connecting rods are used as centering elements.

Making a metal lathe is a creative and unhurried job. You need to think over all the details a hundred times, draw a couple of dozen drawings and only then start making a machine tool in metal. But in any case, straight hands and ingenuity will lead to the successful creation of a practical and functional lathe. Good luck in the field of small mechanical engineering!

A homemade metal lathe is easy enough to make with your own hands, but first you need to figure out what this equipment is.

The lathe was invented many hundreds of years ago. Initially it was a manual equipment, but after going through many different upgrades, it has been transformed and become easier to use.

Today the lathe is an indispensable device in absolutely any production. Now you can find various forms and configurations of this equipment, which are designed for different purposes.

What are they used for?

The lathe can be used in production for various purposes. The main purposes of this equipment include:

• processing of end, internal and external bodies of revolution;
• thread.

Lathe machining is the most common way of making various bodies of revolution, such as discs, shafts or nuts. At this time, there is a change in the shape and size of the workpiece due to the removal of the allowance. The workability of a particular material depends on its structure, as well as physical and chemical properties.

Threading on a lathe is done with a cutter. This tool it is customary to divide by specialists into 3 types:

• prismatic;
• rod;
• round.

But it is also important to remember that the thread on a lathe can also be made using taps and dies. The former help in the production of metric female threads. And the latter are used for threading the outside of bolts and studs. The speed of this kind of work with steel dies is less than five minutes.

Device

The lathe has a rather difficult structure. Its main element is the spindle. So it is customary for specialists to call a hollow shaft made of steel, which has a cone-shaped hole. It is thanks to the latter that the installation is carried out various instruments and mandrels.

The spindle has a special thread, which is primarily intended for fixing a faceplate for a lathe on it. Some types of this equipment have a special groove on this main element. It is with its help that such a danger as uncontrolled clotting of the cartridge is eliminated.

The spindle is the main component of any lathe precisely because it is only thanks to it that really high-quality processing of any part is possible. Therefore, it is important to remember that the assembly in the radial and axial directions had no backlash, that is, a gap or gap between mating parts.

The power of the lathe also depends on the spindle. The performance of this unit will be higher if its main element has a high power of the drive motor.

Also an important component of the lathe is the caliper. It is this element that provides fixation cutting tool and moving it to different directions... There is a tool holder on it, which is also called a cutting head.

Do it yourself

Despite the fact that the lathe has a rather complex structure, you can make a light version of it yourself without spending a lot of time and effort on it. It is also important that large material costs are not required.

The main components of the lathe:

• headstock (front and back);
• frame;
• drive unit;
• centers
• stop for the cutting tool.

Note: vibrations during work on the machine can be avoided if the centers of the device are located on the same axis.

When creating a machine, it is important to know what cannot be used for it electric drive collector type... It is strictly forbidden to do this precisely because it is too powerful for home device, and during its use, the workpiece may simply fly out of the clamps. This threatens to damage the device and can lead to various injuries.

Best for home machine an asynchronous drive is suitable. Its main advantage is that its rotational speed remains unchanged.

Support

As mentioned earlier, the lathe support is one of the components of this unit. It is used to fix the cutting tool and must also have a tool holder installed on it.

Due to the wide variety of different electric motors today, the one that will definitely fit is quite difficult to choose. All drives are classified according to their capacity. For homemade machine, as mentioned above, the best option would be asynchronous motor, since it is he who does not change the rotational speed.

Drill machine

There are many different ways self-creation lathe. Some make this unit with their own hands from a drill. It is perfect for light turning work at home.

In order for this machine to more efficiently perform its main tasks, it is necessary to fix the drill on the bed using a vice and a clamp, which is fixed on the neck.

Important to remember: the bed of such a device must be heavy and have high strength.

Summing up, I would like to note that a home lathe can, no worse than the one used in production, perform simple functions, while its manufacture does not require too much cost.

How to make a lathe with your own hands, see the following video:

In the process of repairing equipment, many men are engaged in the manufacture of the necessary metal blanks in their own workshop. Turning work requires precision and skill. You can give the necessary shape and parameters to metal products using a special machine, additional equipment and tools. Therefore, craftsmen successfully make a multifunctional metal lathe with their own hands.

How to use a metal lathe

A modern industrial machine has a number of characteristics that allow you to perform many different operations. Such a device is equipped with a numerical software device and has complex structure... For a do-it-yourself lathe, you do not need so many functions. It is enough to make a universal mechanical installation that will be conveniently placed on the table in the garage.

The main work performed on homemade milling equipment:

• treatment inner surface, reaming the workpiece;
• turning a cone, groove;
• threading;
• shaped turning;
• trimming ledges and sharp edges;
• turning of cylinders.

The metal lathe is used to machine nuts, bushings, couplings, pulleys, shafts and gears. From such parts, blanks are obtained that allow you to create or improve various mechanisms. Depending on the equipment used, it is fashionable to process not only metal products, but also wooden or plastic blanks on the unit.

A do-it-yourself metal lathe is a full-fledged equipment with a power unit, it has a lot of weight and creates vibration. Before making such a device, it is necessary to carefully consider the design of all the details.

Mini machine for home use has 4 main elements:

1. Frame.
2. Caliper and tool holder.
3. Headstock and tailstock.

Frame

This assembly is designed to secure all equipment in a rigid position. As a base, the bed must be strong and not skewed. The machine can be placed on the table or made floor version by increasing the length of the support. Such a cast bed is made from channels and metal corners. The frame elements are connected by welding or bolted.

Support

Such an element supports the cutting device and is able to move in a predetermined direction and plane for efficient processing of workpieces. If necessary, create complex and non-standard surfaces special attention should be paid to securing this assembly. For smooth movement in the horizontal direction, a screw mechanism is used in the apron. The caliper remains movable, but if necessary, it can be fixed. The cutters in the tool holder must be tightly clamped, backlash increases the risk of injury during operation.

Headstock and tailstock

A gearbox is located in the headstock, which provides different speed spindle rotation, torque value adjustment. In addition, the headstock consists of a turning head and a caliper feeding device. The headstock secures the workpiece.

The headstock at the back of the mechanism ensures that the workpiece or tool is firmly held in the desired direction. Such a unit has the function of cutting threads on a metal lathe.

DIY step-by-step assembly of turning equipment

A homemade lathe is made up of parts that can be found in a garage or workshop. Before proceeding with the processing and assembly of the device, it is necessary to carefully consider the design and characteristics of the unit, its location in the workshop.

Necessary materials

As materials, you can use the tools at hand:

• welded frame (replaces the cast bed);
• power unit - any motor with an electric drive with a power of 800-1500 W from household appliances (a good option- asynchronous motor);
• belts of different lengths can be used as a driving stone;
• screws and nuts for fastening the structure;
• guides, steel bar skids;
• spindle and tailstock (it is better to find ready-made parts, but you can make them from shaped pipe or a piece of sheet metal);
• feed screws - for a do-it-yourself lathe, long rods with a thread in the longitudinal and transverse directions are suitable;
• rolling bearings as elements of rotation;
• squalls of different diameters;
• steel plate at least 8 mm thick - for the caliper and tool holder.

Where to get a lathe project

An important step in creating a homemade lathe is the design and drawing of a diagram indicating the dimensions of the device. As a basis, you can use examples of factory products or drawings of masters, which are freely available on the Internet.

Standard dimensions of turning equipment: 115x62x18 cm. These parameters are considered optimal for work.

Manufacturing process

Making a metal lathe with your own hands is carried out in accordance with step by step guide for main nodes:

1. Formation of the frame according to the drawing data. The pipes are cut and welded together, it is important that the corners are even.
2. Creation of side racks (for this it is better to use another milling machine).
3. Collecting the support installation, connecting the racks with the guides, installing the spacer sleeves on the sides.
4. Fixing bushings for tailstock. If you use these details different sizes, you can achieve a larger stroke.
5. Creation of a platform for the caliper.
6. Installation of the lead screw, fastening the steering wheel and vernier to it.
7. Installation of the headstock platform.
8. Fastening to the headstock machine.
9. Creation of a support and a tool holder.
10. Formation of the engine subframe.
11. Installation of the power unit and its connection to the mains.
12. Test run at idle speed.

A do-it-yourself metal lathe is quite easy to make. It is important to maintain the design parameters, ensure a rigid connection and select a suitable motor.

Video: How to make a metal lathe with your own hands

Those men who like to make something with their own hands, over time, there is a desire to make a metal lathe for their needs with their own hands. According to the owners of such a machine, working on it brings the joy of transforming shapeless blanks into an elegant chiseled thing, created on their own. However, a finished machine is an expensive thing, so we decided to tell you how to make this equipment yourself.

What is the lathe for?

Among the various machine tools for metalworking, the lathe was among the first that could process any material, metal, plastic or wood. This machine allows you to obtain parts of various shapes, in which the outer surface is processed, holes are drilled or boring, a thread is cut or a grooved surface is knurled.

There are many models of lathes that are produced by equipment manufacturers for different purposes. But industrial machines, in most cases, are expensive, large and heavy, and too complex to use at home. An excellent alternative solution would be to assemble a metal lathe with your own hands, this mechanism will be small, easy to operate and will allow you to quickly do small details made of metal or wood.

The lathe makes it possible to manufacture wheels, axles and other parts with a circular cross-section. It is very convenient for a home craftsman to have a wood turning machine in his arsenal. It can be used to carve tool handles, various furniture repair parts, shovel holders or a rake. You can develop gradually, from simple details, gain experience, gradually learn how to grind elements of curly furniture or details for graceful sailboats.

In a lathe, the workpiece is fixed in a horizontal position and the machine rotates it at high speed, then, a moving cutter removes excess material to obtain a part. While the principle of a lathe seems simple, reliable operation will require precise, coordinated operation of the many parts that make up the machine mechanism.

The history of the emergence of lathes

The first devices (of a rather simple design) for processing stone or wood blanks and obtaining cylindrical parts appeared in Ancient Egypt. Subsequently, the design of machine tools became more complicated during a long way of improvement, which led to the emergence of modern precision and high-performance turning equipment.

The beginning of the production of lathes (industrial and independent) was laid by the invention in the 18th century of the lathe, which used a mechanically movable caliper. This design was developed in Russia by the talented mechanic and inventor Andrey Nartov. In his machine, racks, pulleys, screws, gears and other parts were made of metal. But, as before, the machine was set in motion with the help of a flywheel, spun by a person.

When the steam engine was invented at the end of the 18th century, then, in the 19th century, the internal combustion engine, and later the electric motor, the manual drive in machine tools was replaced by a mechanical one. From one common motor using the transmission shaft, the movement was transmitted to the lathes. The shaft itself was fixed on the wall of the workshop or under the ceiling, and each machine was set in motion by means of a belt drive.

At the beginning of the last century, lathes began to be individually equipped with economical electric motors. Mass production of steel requires lathes that provide high-quality parts processing and high production productivity. This demand has spurred improvements in machine tool design.

The development of the design of lathes for turning led to the emergence of a step-pulley drive in them, which made it possible to regulate the number of spindle revolutions. The spindle itself and the lead screw began to be connected by means of a guitar made of gears, which was later supplemented by a gearbox. The next improvement was the separation of the transmission of motion to the caliper from the roller (most turning operations) and the lead screw (threading). A modernized apron mechanism has also been added to the list of innovations.

The advent of high speed steel hastened the development of lathes. Thanks to the new steel, the cutting speed has increased fivefold (compared to how fast conventional carbon steel is processed). In order to increase the varieties of feeds and increase the number of revolutions in lathes, rotation bearings have replaced rolling bearings, and the gearbox in the machine has become even more complicated. Also, realizing the importance of this issue, engineers have developed automatic lubrication of machine parts.

DIY metal lathe: basic units

The design of a homemade simple lathe that allows you to process workpieces consists of the following parts: a frame, a driving and driven center, a tailstock and a headstock, a cutter stop and an electric drive.

The role of the frame is to support all the elements and the machine bed. The headstock is stationary and acts as a base for placing the base rotation assembly.

The front frame contains a transmission linking the drive center to the electric motor. The workpiece is rotated through the leading center. The tailstock can move parallel to the longitudinal axis of the frame. In accordance with the length of the future part, the tailstock is installed so as to firmly fix the end of the workpiece to be machined in the driven center.

Any drive is suitable for a lathe, but an important parameter: power 800 - 1500 watts. The fact is that only the problem of low speeds can still be solved with the help of a transmission mechanism, and the engine power remains the same.

Although any electric motor, even a 200-watt one, can be used in a homemade lathe, it must be borne in mind that when processing large workpieces, a weak motor can overheat and the machine will stop. As a rule, rotation is transmitted using a belt drive, less often a friction drive or a chain drive is used.

For bench machine sometimes a design without a transmission system is used, the chuck and the driving center are attached directly to the motor shaft.

The driven center must be placed on the same axis with the leading center, violation of this rule will lead to vibration of the workpiece.

Conditions that must be met: secure fit, precise alignment and stable rotation. In frontal machines, the workpiece is fixed with a cam chuck, or with a faceplate; in such machines, one leading center is used.

Although the frame can be made from wooden block, usually it is assembled from steel corners or profiles. The frame must ensure rigid fastening of the driven and driving centers; when designing the frame, free movement of the headstock along the longitudinal axis of the machine, as well as the stop for the cutter, must be ensured.

After all the parts of your homemade machine are installed in the correct position, you need to firmly fix them. The purpose of the machine, the size and type of workpieces to be processed, determines the shape of the machine elements and the final dimensions of the installation. In addition, the type and power of the electric motor depends on the intended work, which must create sufficient force that will rotate the part. The motor parameters must be suitable for the expected load.

The most unsuitable for the lathe are collector motors, which tend to increase in speed when the load falls. And in this case, the huge centrifugal force can cause the fixed workpiece to fly out, and this is very dangerous for someone who is near the machine.

However, if you are sharpening small light parts, then you should not worry, and so that the workpiece cannot accelerate uncontrollably, you should use a gearbox for electric motors of this type.

When working with workpieces 0.7 meters long and 10 centimeters in diameter, the recommended motor type is asynchronous, and the power is 800 W. For electric drive of this type the stability of the shaft speed is characteristic when there is a load, and when the load disappears and the workpiece is large, there is no exorbitant increase in the rotational speed.

It should be borne in mind that in independently built lathes there is always a force, the direction of which is along the shaft. Failure to use a belt drive will quickly deteriorate motor bearings that are only designed for perpendicular loads.

So if the motor shaft is directly connected to the drive center of the machine, the motor bearings will constantly be under a load that they are not designed to handle. You can try to compensate for this longitudinal load by making the motor shaft stop in the machine on the back side (or, in some designs of the electric motor, you need to install a ball in the back of it between the end of the shaft and the body - an improvised bearing).

The driven center is located in the tailstock of the machine and can be stationary or rotating. The fixed center is made from the most ordinary bolt, in which the end of the thread is sharpened under a taper. In the hole in the headstock is cut internal thread and by rotating the pointed bolt, the workpiece can be fixed between the centers.

For this bolt, the stroke is designed for 2-3 centimeters, and large distances are set by displacing the tailstock along the axis of the machine. The driven center in the form of a sharpened and ground bolt should be lubricated with (machine) oil immediately before starting work. This will prevent the workpiece from becoming smoke-filled.

How to make a homemade metal lathe

Any craftsman can build a lathe on their own. Although it is homemade, this machine is reliable and easy to use. The owner of the turning equipment will be able to grind or grind new parts, grind metal products, work with wood or plastic, make parts for car repairs, for his own life, or make wooden souvenirs.

At home, you can easily make your own frontal lathe. It is easy to use and has quite a variety of functions. Due to the ease of replacement of parts, the lifespan of such household equipment is very long.
Saw two wooden posts and fasten the bolts in them with nuts, the holes for the bolts should be of the correct diameter, as well as the thread of the nuts.

For the stability of the chisel or the cutter during the operation of the machine, a hand-hand is made for them. It is made from two planks connected with screws or glued together. The lower board should be with a beveled corner and a metal strip that protects the chisel from deformation during movement, and a slot is made in the horizontal board to control and control the movement of the handcuff.

Now it remains to screw on the workpiece with nuts, ensuring its reliability and freedom of movement, and your desktop lathe is ready to use. The workpiece should be machined in both directions in order to obtain the best part shape.

If you do not have a low-power electric motor (approximately 250-500 W), then for a home-made machine you can buy an inexpensive electric motor that was in use, for example, an engine from sewing machine... Also, the most compact lathe can be made on the basis of an electric drill or grinder.

Headstock, front and back is not difficult to make on your own, and if something is not clear, you can spy on the photos of homemade machines. And the frame, in addition to a wooden bar, can be made from a channel, a corner or other high-quality metal.

In everyday life, such a lathe is irreplaceable. If an abrasive or grinding wheel, then on a similar machine, in addition to turning parts, it will be possible to sharpen the tool, as well as grind or polish the surfaces. And if you attach the adapter and drill chuck to the bulk, then your machine can be used for milling grooves or drilling holes in parts.

Thus, having made a metal lathe with your own hands, you will get a universal assistant in household... The variety of ways to use such a machine encourages you to try your hand. Self-made, small lathes are excellent at home-scale turning or grinding tasks.
