How to make a jigsaw with your own hands drawings. How to choose a desktop jigsaw: rating

For slotted thread and cutting small parts from wood, plywood, plexiglass, plastics and other materials use jigsaws various designs and types. It can be manual ("pioneer"), mechanical and electric jigsaws. Various magazines cited diagrams of home-made jigsaws driven by electric motors and even electric drills. How to make a homemade jigsaw, read this article.

Using a desktop jigsaw at home, you can make furniture, beautiful patterned shelves and much more. The mechanism allows you to cut smooth and sinuous parts from wood, plastic and dense foam materials. In order for a home-made device to fully meet the requirements, it is necessary to carefully select the appropriate design.

Design and specifications

The device of any model of an electric jigsaw machine must contain:

• saw;
• crank assembly;
• drive unit;
• saw tension device;
• Desktop;
• auxiliary mechanisms.

The processed material keeps within on a desktop. Some models are equipped with a rotary device that changes the slope of the surface. To make it easier to mark the material with your own hands, graduation is applied to the surface.

The larger the table, the longer the cut can be made. On average, this figure is 30 - 40 cm.

Drive power for homemade desktop machine is about 150 watts.

The crank assembly converts the rotational movement of the drive into reciprocating and transfers it to the saw. On average, the oscillation frequency of the file per minute is 800 - 1000. The vertical movement amplitude is not more than 5 cm. Some models allow you to select the movement speed depending on the properties of the material.

file manual jigsaw can work with wood, plastic with a thickness of not more than 10 cm, having a length of up to 35 cm. For different types of materials and work, the files change, their width is 2 - 10 mm.

The manual tension device secures the saw blade for uniform sawing, it is a helical or leaf spring.

Types of machines

Structurally, all jigsaw devices can be divided:

• with bottom caliper;
• with double support;
• on suspension;
• with degree scale and stops;
• universal.

The most common are models with a lower caliper. Their bed is divided into two halves: lower and upper. At the top there is a cutting and cleaning module. At the bottom - a control module, an electric motor, a transmission mechanism and a toggle switch. Allows you to process sheets of material of any size.

Double caliper models differ in that there is an additional rail on the upper half of the bed. Such devices are good for creating oversized parts. They are easier to install than the previous version. Both models allow you to process material no thicker than 8 cm. A working table with angle and height adjustment is attached to the machine.

Suspension machines are not equipped with a monolithic bed, they are very mobile. During processing, the cutting module moves, not the material. The working module is usually attached to the ceiling with its own hands, so the size of the material is unlimited. Cutting tool moves manually independently of the bed, creating very complex patterns.

Machines with a degree scale and stops are good for precise work on drawings. The design allows you to avoid errors. Universal jigsaws can perform several operations associated with cutting: drilling, polishing, grinding.

Making a machine with your own hands

Drawing of a homemade desktop jigsaw: 1 - rocking chair insert (2 pcs.), 2 - earring (2 pcs.), 3 - table, 4.6 - screws, 5 - thrust, 7 - eccentric, 8 - base, 9 - axes of earrings, 10 - upper rocker, 11 - rocker axis, 12 - lamb, 13 - tension screw cross member (2 pcs), 14 - tension screw, 15 - rocking stand, 16 - bottom rocker, 17 - box, 18 - two-strand pulley, 19 - intermediate shaft, 20 - rack bushing, 21 - table plate, 22 - bearing with cover (2 pcs.), 23 - electric motor pulley.

In the drawing of a do-it-yourself desktop machine, the number of nodes must be minimized, these are: a rocking chair with a fixed saw, a frame and an electric motor. You can take the engine from an old electric machine.

Owners of a manual jigsaw were more fortunate. From a sheet of plywood, you can make a stand and attach a jigsaw to it. To fix the jigsaw with your own hands, you will have to make holes in the base of the tool. The most simple model ready.

Now about more complex and functional ones. The do-it-yourself bed is made of 12 mm plywood, thick plastic or textolite. It is a base, a box for placing the engine and mechanisms, and a work table. On the other hand, we have a rocking chair with an eccentric. They are interconnected by a metal plate with bushing bearings. The whole structure is fixed with screws. To mount the intermediate shaft, prepare a pair of bearings. The two-strand metal pulley is mounted on the shaft as tightly as possible, the screw connection is fixed. In the same way, you can make an eccentric.

To change the amplitude of the movement of the rocking chair, four round through holes with threads are made on the eccentric flange, remote from the axis at different distances. By changing the installation location of the screw, the swing of the rocking chair is adjusted. It is a pair of wooden yokes hinged to a rack. The rear ends of the rocker arms contain through cuts, tension screws are inserted into them. A file is fixed to the ends in front, movable due to metal hinges. Before fastening, the file is inserted into the groove of the working surface of the table.

The saw blade attachment mechanism is very important. In the manufacture homemade device with his own hands, he should be given special attention. The insert plates of the rocker arms carry constant loads during movement, therefore they are rigidly fixed and tightened with screws and Grover washers. The fastening earrings should not be strongly compressed by the screws, allowing the hinge axis of the plate to move.

It is advisable to make a rocking chair from a single piece of material. A groove for the rocker arm is made on the upper side, at the lower end an opening in the shape of a rectangle is cut out for the second rocker arm. To make it easier to cut holes, you can fold the stand in two parts.

Video on how to make a jigsaw machine with your own hands:

If you are into carving and making figurines or parts out of wood, plastic or similar material, you cannot do without a tool whose name is reminiscent of the distant Soviet past: this is a jigsaw.

Jigsaw jigsaw strife, now on sale there are also "pioneer" elementary manual models, and electric modern tools, only remotely resembling the usual saws.

You can also make a jigsaw yourself: in the technical literature and the network, many diagrams and drawings of electric jigsaws are offered.

It is not difficult to make such a device, and you will get significant benefits from it. You will be able to independently engage in the production of furniture you need and implement the most daring creative ideas for the interior.

An example of the manufacture of a jigsaw machine.

A homemade jigsaw will help you professionally make even parts of the most bizarre shapes. First you need to decide on the most suitable design for you.

Technical description and components

The schematic diagram of any jigsaw machine is the same for different models.

It must include the following parts:

• file;
• drive with a power of about 150 W;
• rocker for tensioning the file;
• working surface with graduation;
• drilling block, etc.

Consumables are fixed on the working surface. In advanced models, there are special devices for rotary movements of the part, in which the working surface can change the angle of inclination.

The dimensions of the surface will depend on your production and creative plans: the larger the parts you are going to cut, the larger your production table should be. Traditional sizes are usually around 30 - 40 cm.

The types of saw blades are varied. They depend primarily on the consumable material. The dimensions of the parts for cutting are also important. Conventional saw blades for working with wood have a length of about 35 - 40 cm. They are able to saw parts made of wood or plastic with a thickness of no more than 100 mm.

With different types materials, the files also change, this mainly concerns their width: from 2 to 10 mm. Files can vary in the type of their tails - with or without pins. They are fixed in a special device for their tension and even sawing. To do this, they have spring-type springs.

Another one the most important detail machine: crank assembly. Its function is difficult to overestimate: it is he who transmits the movement from the drive to the file, turning the rotational movement into translational.

Assembly drawing of a jigsaw machine.

Due to this, the file begins to oscillate with a high frequency, the speed of such oscillations is on average about 800 - 1000 rpm. It is important to remember about the amplitude of vertical vibrations, it should not exceed 50 mm.

In advanced modern jigsaw models, the speed varies depending on the type of consumable. Most desktop models operate in two speed modes. Most often it is 600 and 1000 rpm.

Model range of jigsaw machines

Most often, machines differ in their electric drive power, the range of values ​​​​is huge: from 90 to 500 watts.

Also, these devices are divided into varieties based on their fundamental design:

• universal;
• on suspension;
• with graduation;
• with a caliper in the lower position;
• with double support.

Jigsaws with bottom support

Scheme of machine design elements.

The most used and popular models are machines with a lower support. Their feature is the division of the working frame into the upper and lower parts.

While the upper section contains only one sawing and cleaning device, the lower section contains many working elements: an electric motor, a switch, a transmission unit and a control unit. This design makes it possible to cut sheets of materials of almost any size.

Machines with double support

A home-made jigsaw with a double caliper differs from the lower caliper by the presence in the upper section of a special additional bar and a desktop with the ability to change the angle of inclination and overall height.

These models are designed to work with details oversized. Such a machine is easier to make than the previous model. There are limitations in the materials with which you can work on it: their thickness should not exceed 80 mm.

Hanging machines

The name speaks for itself: the model is mobile, it works without a frame. The fundamental point in this design is the movement of the cutting file, and not the consumable. The module itself is attached to the ceiling, the saw is set in motion manually.

All this gives serious advantages: in this way you can create the most complex patterns, the surface dimensions are not limited by anything.

Graduated devices

The presence of stops and a degree scale make it possible to work according to technical drawings, without the slightest error.

Universal machines

Such devices are usually called electric jigsaw. Their feature is the ability to perform several operations such as grinding, polishing, sawing, etc.

How to make a jigsaw machine with your own hands?

We will not stop at the manufacture of the simplest machines: you can easily find such manuals with video support on the net. Let's talk about homemade machines from an electric jigsaw.

Assembling the machine with your own hands.

Here is the sequence of work for their manufacture:

• We make a bed from plywood sheet or plastic.
  The main thing is that the thickness should not be less than 12 mm. The function of the bed is a foundation, a working surface and a place for fixing mechanisms and an electric motor.
• We place a special rocking chair with an eccentric on the opposite side.
  We connect them using a metal bar with bearings. All fasteners in the design are screw.
• We make installation of an intermediate shaft.
  To do this, you need to prepare two bearings, put the pulley on the shaft as tightly as possible, then carefully fasten it with screws. Similar actions are performed with an eccentric.
• At the rocking chair, the amplitude of movements should change.
  To do this, you need to change the place of attachment of the screw, for which we drill exactly four threaded holes on the eccentric flange. The holes should be located at different distances from the axis. With a change in the place of attachment of the screw, the swing of the amplitude of the rocking chair will change.
• We make a rocking chair: this is nothing more than wooden rocker arms, into whose rear ends the screws that you built in the previous paragraph are inserted, these are tension screws.
  The rocker arms themselves are hinged to the rack. We fix the file on the front ends of the rocker arms. Previous and given stages must be done with special attention and thoroughness. The fact is that fixing the file is fundamentally important thing. Rocker arms with plates are subjected to constant loads during movement due to their rigid screed with screws.
• For a rocking chair you need a stand.
  It will be better if it is made from a whole piece of material. We make a groove for the first rocker arm on the top of the rack. From the lower end we have a special rectangular opening for the second rocker arm.

Your machine is ready. wish cool ideas and their quality implementation.

Since childhood, we have been familiar with the technology of sawing with a jigsaw. The principle is simple - a fixed part is placed on a stand with a technological cutout, the cut is made by moving the file. The quality of work depends on the firmness of the hands and the skill of the worker.

In this way, you can literally cut lace from thin wooden or plastic blanks. However, the process is laborious and slow. Therefore, many masters thought about small-scale mechanization.

A simple design from the last century

Even in the magazine "Young Technician" drawings were offered on how to make a jigsaw machine with your own hands. Moreover, the design does not imply an electric drive, the drive works from muscular strength, like knife grinders.

The machine consists of the main parts:

• bed (A)
• desktop (B) with a slot for the canvas
• lever system (B) for holding saw blade
• flywheel (D), which is the primary drive pulley
• crank mechanism (D), combined with the secondary drive pulley, and driving the levers (B)
• pedal assembly (E) with a crank mechanism that drives the flywheel (D)
• saw blade tensioner (W)

With the foot of the foot, the master sets the flywheel (D) in motion. With the help of a belt drive, the crank mechanism (D), connected to the lower lever (B), rotates. A file is stretched between the levers, the degree of tension is regulated by a lanyard (G).

With a well-balanced flywheel, a sufficient smoothness of the saw blade is ensured, and such a home-made jigsaw machine allows you to massively cut out the same type of workpiece, saving time and effort. In those days, jigsaw saw blades were produced in the form of a flat tape with unidirectional action.

Therefore, in order to obtain patterns complex shape I had to rotate the workpiece around the canvas. The dimensions of the workpiece are limited by the length of the levers (B).

From mechanical jigsaw to electric one step

The foot drive cannot give real freedom of action and uniformity of the sawing stroke. It is more reasonable to adapt an electric motor for a crank mechanism. However, if you use a desktop jigsaw from time to time, it makes no sense to make a stationary structure with its own motor.

A desktop jigsaw is an indispensable thing for any owner who is used to doing housework on his own. Especially electric jigsaws are good for residents of the private sector, lovers manual labor and summer vacation. From its prototype, an ordinary manual jigsaw, desktop electric model gone far enough. A desktop jigsaw makes it easier and faster to cut, not to mention improving quality.

The concept of desktop jigsaw

The jigsaw is a saw, which is characterized by reciprocating movements of the saw blade, which acts as a working body. It has a ski designed to guide the saw blade when moving over the surface that is being processed, and making movements at a frequency of up to 3000 vibrations per minute.

This tool was invented in 1946. Its creator is Albert Kaufman, who replaced the needle in a sewing machine with a blade. The tool appeared on sale in 1947. The manual electric jigsaw has a body with a flat platform and a handle. The main difference between an electric jigsaw and a manual jigsaw is its greater functionality and cutting quality.

Located inside Electrical engine and a special mechanism that drives the blade. In stationary jigsaws, there is no handle, and the platform is located on top. In front of the mechanism there is a guide, in the lower part there is a retractable blade that moves and makes cuts.

The tool works as follows: a table jigsaw file is securely fastened with clips in the slider. Reciprocating movements have a frequency of up to 3000 strokes and can be adjusted. The support platform allows the jigsaw to focus on the part being cut, so the work is carried out very accurately.

The purpose of the desktop jigsaw

The jigsaw is an essential accessory for every workshop and every hobbyist. His thin file can successfully cut plywood, copper, iron, thick boards, brass, steel. Tools can be motorized, foot or hand-operated and are more productive. An electric jigsaw is simply indispensable for carpenters, woodworkers, furniture designers, drywall workers who make complex parts.

An electric jigsaw can perform straight and curved cuts on workpieces with complex shapes and various sheet materials without breaking the outer contour. Most often, desktop jigsaws are used for cutting wood and wooden boards, figures with a complex outline of laminate and drywall, plastic blanks, also for cutting sheet metal.

Desktop electric jigsaw makes clean cuts of complex shapes and works with small
details. Due to the stable and fixed position during operation, high cutting accuracy is achieved. The file has a stable course thanks to the tension system and guides, which manual jigsaws lack. Big size table makes it stable, so that exactly the specified direction of sawing is observed.

Types of jigsaws

To date, the power tool market is represented by big variety jigsaws, which differ in the nature of the application, technical characteristics, type of power supply and design features. AT construction stores can buy desktop jigsaw for every taste and budget.

By design features, it is difficult to classify, because each manufacturer seeks to provide its products with features that are designed to facilitate and improve the operation of the tool. In this regard, the shape of the handle is an important parameter.

Two types of handles have settled - mushroom-shaped and D-shaped. A jigsaw with a staple-like handle requires one-handed operation. This increases the possibility of using a jigsaw, but somewhat negatively affects the quality of the material cut.

Mushroom handles allow for more accurate cuts when holding the jigsaw with both hands, after fixing the workpiece to be cut. The choice of a jigsaw with a certain shape of the handle depends on the financial capabilities and personal preferences of the buyer. It is worth choosing the jigsaw with which it will be more convenient to work.

Household jigsaws are not designed for intensive use, but the low price of a desktop jigsaw and the power that is enough for household needs make them indispensable in household.

Professional jigsaws are characterized by high wear resistance and the possibility of many hours of daily use (up to 8 hours). The significant power of such jigsaws allows you to process materials of great thickness. Extended equipment and improved features are reflected in the price.

Among professional jigsaws, industrial ones also stand out, which are characterized by greater adaptability to complex operations and drive features - for example, increased power supply voltage. Industrial models are machines that are designed for the woodworking industry.

By type of power supply, there are network and battery electric jigsaws. Network models are powered by a standard voltage power supply. If performance is important to you, then you should choose a corded power tool.

Cordless jigsaws provide independence from the presence of sockets and greater mobility during work. When buying a battery model, you should pay attention to the type of battery. Increased performance is inherent in lithium-ion batteries. Battery capacity is responsible for the duration of work without recharging.

Advantages of desktop jigsaws

The desktop electric jigsaw is a stationary design, so this type of cutting tool has many advantages. Modern models can work with wooden materials 40-50 mm thick. A narrow saw acts as a working body, which performs vertical reciprocating movements. Due to the peculiarities of the notching of the teeth and the mechanics of the movements of the file, the material is cut out by moving upwards.

The desktop electric jigsaw allows you to cut out complex decorative details, to make longitudinal, straight, oblique and transverse cuts. The wide tabletop allows you to process large parts and make cuts inside wide workpieces. Reliable fastening protects the body from unnecessary vibrations and allows you to have a good position of the material, so the motor can work without overloading.

The advantages of desktop jigsaws include good accuracy and clarity of cuts, high safety and ease of use, wide customization options for the material and the required detail of the cut workpieces.

If you need to cut out details small size, a manual jigsaw will not be very convenient. It is quite heavy, so you have to hold it with one hand and guide the workpiece with the other. And the desktop jigsaw is devoid of this drawback. Perhaps the inconvenience is too big sizes and the difficulty of working with large parts.

The desktop jigsaw is a kind of mini-machine for cutting workpieces. If you buy a jigsaw in a store, most likely there will be an opportunity to select the power and adjust the frequency of the saw strokes. However, you can make the simplest homemade desktop jigsaw, and very quickly. You will need a manual jigsaw, a few screws, a piece of plywood small sizes and only one hour of work.

Making a desktop jigsaw

A carefully made jigsaw will not be inferior to a factory-made one, and in some respects even surpasses it. It is not difficult to assemble such an electric jigsaw if there is necessary materials. Next, we describe a simple circuit such manipulations.

The design of the jigsaw includes the following components: a handle, a switch button, an insulating washer, a power cord, a frame, a heating thread, a screw clamp and an earring. First you need to make a frame. You will need a duralumin pipe with an outer diameter of up to twelve millimeters.

You can also use textolite with a thickness of at least ten millimeters or thick plywood for the base. But keep in mind, the lighter the frame, the more convenient the jigsaw will be to use. Be sure to provide a channel so that you can later lay the power cord. most best form A frame is one whose side is bent 45 degrees.

Next, you need to make an earring. It is made of copper sheet with a thickness of one millimeter. After that, it is fastened with screws to the frame, where it connects to the handle. Thus, the screw, wing nut and earring will form a clamp in which the heating thread can be fixed. The thickness of the duralumin sheet should be up to 0.8 millimeters. It is necessary to make clamping cheeks from it, between which there is a button-switch.

After that, you need to cut a gap in the plywood through which the file can pass. It can be done with a drill. To do this, it is necessary to drill holes along the marking line, and smooth the transitions. Instead of plywood, you can use plastic, metal, plexiglass and others. Next, you place and drill mounting holes on the plywood and the base plate of the jigsaw.

Then you need to fix the jigsaw with screws on the plywood base so that the file can pass through the gap. You attach the structure to the table with a clamp so that the file is pointing up. You can also secure the platform in any way you can.
The jigsaw file remains conventional, but the possibilities for good sawing are expanded by freeing up the hands.

You can use a nichrome coil from any household heating device (for example, an iron) as a heating filament. It must be secured with tension between the ends of the frame bends. To heat up the thread, you need to apply a tension of about 14 V. To control the operating mode, you can use a rheostat.

The current is determined by the thickness and length of the nichrome filament. With the help of a rheostat, it will be possible to set the optimal current strength (no more than 3-5 A), which will affect the temperature to which the thread is heated. Before starting work, it is necessary to determine the current strength. But keep in mind, if too high strength the cut material can be caught by the flame, and if it is insufficient, it will not be taken. A do-it-yourself desktop jigsaw will allow you to cut out figures with complex contours from different kind materials.

Rules for using a desktop jigsaw

When working with desktop jigsaw you need to follow some rules:

1. Do not press hard on the tool while cutting, otherwise best case the needle will break, at worst, you will spoil the work.
2. Change blades from time to time. An old saw can spoil and destroy the surface of the material.
3. If you work with organic glass and non-ferrous alloys, the surface of the product must be moistened with water. Such an operation will speed up the process and extend the life of the saw.
4. If you are cutting a surface with a thickness of less than one millimeter, place a sheet of wood or plywood under the material being processed.
5. Before cutting, it is necessary to fix the material. It is better not to make long cuts by hand, the line may turn out to be crooked.
6. For cutting different materials appropriate blades are needed, with a special pitch and length.
7. Rotate the tool by turning only the back of the tool.
8. When cutting the laminate, an adhesive tape is glued to the cut line, which protects the material from chipping.
9. If the need arises for curved cuts, set the jigsaw pendulum to a minimum.

If you have not yet fully understood how to make a desktop electric jigsaw, watch a video about this procedure. This tool allows you to cut complex parts from wood and other materials, to make longitudinal, oblique, straight and transverse cuts. With a jigsaw you can process large parts, wide workpieces and small items, which is not superfluous at home.

An electric jigsaw is a type of woodworking equipment. Currently, the choice is presented not only in the usual manual version but also in electricity. These models, for example, Vario 502 dks, dremel have high performance, are quite easy to use, are completed large quantity removable components.

You can use these devices both in the household and in production. Today, such a mechanism can be bought ready-made or made by hand, for example, from an old sewing machine.

1 Technology of use

The main working element of a manual jigsaw is small nail files, which usually have a length of 50 to 120 mm. This is driven by an existing electric motor and performs translational movements vertically during the processing of the product. In some mechanisms, it works according to the pendulum type.

The workpiece itself in this design is attached directly to the sole of the equipment. Such fixation makes it easier for the worker to operate the system and freely adjust the angle of the tool. The safety of the operator in this design is ensured by the presence of a special screen.

These models appeared in mass sale in last years. Previously, they tried to make them for home use from a sewing machine. Today, there is no need for this. The choice of models is very large.

1.1 Advantages and disadvantages of using electric jigsaws

To strengths It is this technique that must be attributed:

1. Possibility of using the device for a wide range of woodworking thanks to a large number replacement sheets.
2. Greater reliability in use: due to the wide web of such a mechanism, it is possible to avoid breaking parts made of wood, tiles during processing, and also to perform any complex contours with a minimum of effort.
3. The ability to feed the wood blank with two hands by attaching it to the canvas. Previously, without such a device, working with hand-type samples was much more difficult.
4. Simplicity in the processing of any canvases - even a relatively small the jigsaw can easily handle wood with a thickness of 50 mm, not to mention more powerful models.
5. Wide range of processing options.

Among the disadvantages of using such a device, a short stroke of the samples is usually noted, due to which the work with thick canvases becomes much more complicated.

Also, the inability to make the bending radius as small as when using a manual sample (due to the features of the saw blade attachment).

2 Scope of machine tools

Modern electric jigsaws are applicable for the following work to choose from:

1. Sawing complex contours from a sheet blank.
2. Processing inner surface workpiece without violating its contour integrity.
3. Finishing of some samples.

A desktop jigsaw is used mainly for processing wooden blanks. It is most often used in the manufacture of furniture, musical instruments. In recent years, they have also often been used for the production of decor items, as well as souvenirs.

2.1 Consumables

The main consumables that a desktop jigsaw has are files, including spiral ones. They differ in length, size of teeth, distance between them. and are selected for each material individually.

Usually equipping a jigsaw machine with their own hands and buying files for it, experts recommend navigating the choice Supplies to the following features:

1. For sawing on blanks made of wood or plywood, saws are selected in increments of 2-4 mm.
2. Metal samples, as well as plastic, are usually processed by choosing 1-2 mm files, including spiral ones. Masters who form reviews on the use of such components recommend stopping here on models with a wavy edge. The choice of those is very large.
3. When working with tiles, special saw blades with an abrasive coating are used.

You can choose these elements for processing wood and other materials not only based on reviews, but also based on specifications equipment of your choice.

After all, almost every machine has a list of consumables, including all files suitable for it for certain products.

Also, do not forget about additional elements such a design, which, for example, in the models Dewalt, Dremel, Holzstar, Vario 502 dks include a drilling unit and an air pump. Their choice is great.

2.2 Design features of jigsaws

Currently, an electric jigsaw machine, in addition to those products that are created at home with their own hands, is presented on the market in a huge amount various products. Their choice is really wide. Among them are the models Dewalt, Holzstar, Vario 502 dks.

They are classified according to the following features:

In order to choose the right jigsaw, you need to It is necessary to analyze the device in all respects. And then you can get the perfect component for any task. You can also assemble a desktop jigsaw with your own hands using general recommendations for the production of such devices.

It will not be difficult to do it yourself from a sewing machine, or another similar mechanism. The main thing is to study the design device well, to choose necessary components and do everything to make the model reliable.
