Stationary jigsaw machine. How to make a homemade jigsaw in your home workshop. Video: Sewing machine jigsaw

The era of the electric tool did not come with the first electric drills, but when the electric motor became an attribute of a tool of a narrower focus: scissors, hacksaws, a wrench and, of course, a jigsaw.

Moreover, the electric jigsaw was one of the first in this series. Today it is one of the most popular tools in the home (and not only) workshop. And first of all, we are talking about a hand tool.

But we are considering jigsaws in this article, and this is practically stationary devices, which often have their own specific place in the workshop, for for comfortable work they require a base with the given parameters: height so that the arm placed on the desktop has a bend at the elbow at 90º and stability so that it dampens the vibrations of the machine itself.

What are jigsaws for?

Jigsaw machines are primarily designed for sawing parts or elements of complex configuration in sheet material: wood, plywood, MDF, fiberboard, chipboard, plastic, aluminum. Also, with their help, the internal contours of products are cut out with preliminary drilling of the material being cut.

Such a tool, unlike manual or electric jigsaws, leaves both hands free for those working on it, which greatly facilitates the work and allows you to perform it with the greatest accuracy. Most jigsaws, provided correct selection and installation of nail files, allow cutting even in rather thick workpieces, with strict observance of an angle of 90º with respect to the plane of the workpiece.

Also, many models have an inclined table, which makes it possible to perform complex patterns at strictly specified angles other than straight, which is almost impossible when using manual or electric jigsaws.

Except home use, they are widely used in furniture production and manufacturing plants musical instruments. However, quite often they are replaced laser machines, but the burnt edges left by the latter do not make their use ubiquitous.

General drawing, structural features of desktop jigsaws

The most common layout for jigsaw machines is as follows:

It includes:

a frame (or body) on which all components and mechanisms are attached;
drive, often from the electric motor with a V-belt to the crank;
a crank mechanism that converts the rotational movement of the motor shaft into the reciprocating movement of the file;
double rocker with a tensioner and attachments for sawing;
desktop, sometimes with a mechanism for turning in a horizontal plane at a given angle.

Previously, miniature jigsaws with a somewhat simplified design were on sale, but it was precisely because of it, which led to a quick failure of the saw blades due to their short stroke, that their production was discontinued.

Most of the currently produced desktop jigsaws work with files 200 - 350 mm long and have a working stroke of 30 to 50 mm.

The differences between the machines mainly consist in the power of the electric drive (from 90 to 500 W - for most models), as well as the type and methods of attaching saw blades. Optimal, in our opinion, is a power of 150 watts.

And files, in addition to length, can vary in width (from 2 to 10 mm), type of shank (with or without pins) and thickness (from 0.6 to 1.25 mm).

In some models, you can install the simplest, often called "Soviet", files for manual jigsaws, which is a big advantage. To implement just such an opportunity, owners of jigsaws that do not have it often improve the fastening of their devices by installing clamps from a manual jigsaw on them.

Most desktop jigsaws have 2 speed modes: more often - 600 and 1000 rpm, which is very useful when working with materials of different thickness, hardness and viscosity. The presence of the already mentioned turntable for 99% of the work performed on the machine - the function is useless.

Also, most jigsaws are equipped with additional devices, such as:

compressor for blowing chips from the cutting line;
sawing area illumination;
drilling block, etc.

It’s impossible to call these devices useless, but it’s still not worth focusing on their presence when choosing a desktop jigsaw, since the same functions can be successfully performed:

a compressor for an aquarium, with a blowing power chosen by you, is often more efficient than a regular one;
a table lamp or a carrier with a luminous flux that is comfortable for your eyes;
electric drill or screwdriver.

Even more complex devices, such as engraving drills that your machine can be equipped with, generally cause some bewilderment, but we’ll say right away that it’s better to have such tools that are not tied to a jigsaw (or any other) machine. Their mobility is often more expensive than the extended functionality of this very machine. Plus, it's not all free.

We make a choice of a manufacturer of a jigsaw machine

Most often, the Russian consumer has a choice of jigsaws Proxxon, Dewalt, Hegner, Xendoll, Bison, JET, Encore Corvette and Kroton. Each of them has its own advantages and disadvantages. We would, in terms of reliability and compliance with the characteristics declared by the manufacturer, single out the machines of the German company Hegner. Yes, and the line of this equipment they have is more authentic than many, but be sure to insist on sea trials when buying, regardless of which machine of which company you are going to buy.

And even if it is possible to choose from 2 identical machines, demand to turn on both. Buy one that has less noise and vibration.

Do-it-yourself jigsaw machine

Finding a drawing of such equipment on the Internet is a rather trivial task, but we do not consider it appropriate to single out any specific one, due to completely different approaches to implementation, both the very idea of \u200b\u200bbuilding such a machine, and the selection of materials, type of drive and other things. We will offer several concepts for a homemade jigsaw machine and briefly analyze the advantages and disadvantages of each so that you can figure out what is best for you.

First: the easiest to implement, suitable for most tasks for the manufacture of parts with a rather complex contour at home.

There are many options for attaching a manual electric jigsaw to a tabletop that serves as the desktop of the machine. Choose any, or offer your own and share with the readers of our site, for which we will be grateful.

The video also shows how to make a complex contour using not the thinnest file. And the main drawback of this design is the impossibility of using thin files, which makes it difficult to manufacture openwork parts.

Second: wooden. Interesting due to the fact that the material is available, easy to process and repair.

In our opinion, it is interesting to use the same manual electric jigsaw, which is rational for two reasons:

if necessary, it can be used as independent tool, which was made;
the drive has a built-in speed control, oscillation amplitude, eliminates additional mechanisms that reduce the reliability of the design.

However, for those who like to craft, there is alternatives manufacture of a wooden jigsaw.

When using a drill or a screwdriver with an adjustable output shaft speed as a drive, it will also be possible to smoothly adjust the frequency of the saw blade.

Moreover, the control of this process can be transferred to the pedal with the help of a simple device, which will make the work even more comfortable, and the cut more accurate. Such jigsaws must be well reinforced with braces and stringers and securely fastened to the floor so that they do not move during operation.

Third: metal. There is no doubt that this concept is the most reliable and durable (provided that serious manufacturing errors are excluded), but also the most expensive. It makes sense to implement it if there will be a large number of works and you will be able to save a sufficient amount by using the materials you already have. Otherwise, there is not so much sense in making such structures with your own hands, given that inexpensive factory-made jigsaw machines can be purchased for less than 4 thousand rubles.

Of course, the latter does not matter if you are interested in the process of technical creativity itself.

Dear readers, if you still have questions, ask them using the form below. We will be glad to communicate with you;)

A jigsaw machine is a device that provides high-precision implementation of operations related to the processing of workpieces from different materials. With the help of such a machine, you can make an even or curved cut of varying complexity on sheet blanks. When cutting into inner surface does not change the outer edge of the material. On such a machine, you can work with timber, plastic, some types of metals. If you have to use a jigsaw often, the machine is impossible better fit for this purpose.

Device and work

The main components of the entire design of the machine are a table, a motor, a saw, a crank and tensioning mechanisms. In addition, there are additional functional elements.

The material to be processed must be on the working table. The material from which the countertop is made is very important. Choose a cast rather than a stamped table. On working surface there may be additional rotary mechanisms with which you can change the angle of the table and cut. The dimensions of the table are determined maximum dimensions workpiece being processed. Most models have a saw length of 300 to 400 mm.

The power of the power unit affects the list of materials that can be processed on a jigsaw machine. If you plan to process not only wood, then you need to choose models whose power is more than 200 watts. Home master a 150W device will suffice.

The jigsaw is the main working unit of the equipment. The file is selected depending on the type of cut and the density of the workpiece, in addition, you need to take into account the width and thickness. Small-sized devices can cut timber up to 50 mm thick, more powerful professional machines cope with workpieces up to 100 mm in thickness.

The rotational moment created by the motor is converted by the crank mechanism into the movement of the saw unit. The tensioner tensions the file as it moves through the material.

The principle of operation of this device is quite simple. The workpiece is fixed on the table, then, under the control of the master, the saw cuts.

A wood jigsaw has a number of advantages over other more simple devices. First of all, the device guarantees a high-quality cut. The machine makes it possible to carry out longitudinal, transverse or angular cuts with maximum precision, with the formation of a smooth edge. Another advantage is the fact that the hands of the master remain free, therefore, the workpiece is easier to control, therefore, with a certain level of skill, the most complex bends can be obtained. It is also worth noting that the presence protective covers minimizes the possibility of getting herbs.

Jigsaw blades most often have a length of up to 35 cm and can cut material up to 10 cm in thickness. The width of the nail files can be very different - from the thinnest two-millimeter to coarse ten-millimeter, with a thickness of 0.6 mm to 1.25 mm. Please note that even the thickest and widest nail files will easily break if the necessary tension of the nail file is not provided along the entire length. Springs and helical springs are responsible for the tension.

Quite often, such a machine has air pump, which cleans the cutting line from sawdust by blowing, as well as a drilling block. The block is extremely useful, because if it is present, the master is not distracted by the connection electric drill and drilling holes - everything is done on the working plane of the machine. But these machines are also more expensive.

There are several options for creating a do-it-yourself jigsaw machine. For the most simple machine a jigsaw table can be created quite quickly. The main advantage is simplicity. The device is simply mounted on a countertop or workbench and at the end of the work it is also simply disassembled. Minus is small area. The simplest machine has the following components:

plywood sheet
fixing screws
a few clamps.

As working basis you can take a leaf laminated plywood, in which you need to drill holes for mounting fasteners and for the saw itself. Plywood should be taken in a thickness of more than 10 mm. At the same time, it is also necessary to drill holes for the mounting screws in the sole of the jigsaw. Homemade construction attached to the workbench with clamps. It is worth noting that the heads of the screws for fastening must be sunk into the surface of the sheet so that they do not interfere with work. Such a device can easily cope with the processing of small workpieces, the thickness of which does not exceed 30 mm. A drawing of such a machine can be found on the Internet, and assembled with your own hands in your workshop or garage.

The second version of the machine has the following components:

chipboard frame
tube for vacuum cleaner
a piece of laminated plywood for the machine cover
confirmants.

This option is a little more difficult to assemble, however, and this task is completely solvable. The bed is created from chipboard. It has a back wall and two sidewalls. In order to get to the power button was not difficult, the front wall did not need to be installed. In the back wall you need to drill holes for the vacuum cleaner tube and cord. It is better to cut the cover for the device from a piece of laminated plywood 10 mm thick. After that, the whole structure is fastened with confirmants. The jigsaw itself can be installed in a similar way with the previous option. On a machine created in this way, you will be able to process larger workpieces. Of the minuses, we note that while working with large workpieces, the jigsaw saw can deviate to both sides and even back. Consequently, the quality of the cut is reduced. However, this can also be dealt with. It just needs to be installed homemade machine support bracket. In this case, the jigsaw blade will move between two 11 mm bearings screwed to the L-shaped steel strip. The back of the canvas rests against the wall of the bracket itself. Such a system will prevent the web from deviating from a given trajectory.

The bracket must be attached to the frame, which is created from 50 by 50 mm bars. The frame is lowered or raised, it all depends on the length and thickness of the workpiece being processed. To ensure the mobility of the frame, it, together with the stop, must be fixed not tightly to the side of the machine, but pressed against it with a hardboard, steel or textolite plate. Next you need to install vertical rack frame between hardboard and bed. The machine will become even more convenient if you attach an additional limiting bar to it, with which you will cut the material into workpieces of the same thickness and length. This limiter is attached to the machine with clamps. It can be made from wooden beam, as well as aluminum or steel corner.

To create a table for a jigsaw machine from chipboard, you need to have certain carpentry skills, because the process of connecting its tsarg with legs must be carried out in a tenon groove. The thorn-groove itself can be replaced with a connection using dowels, wood glue and self-tapping screws. The cover must be removable to guarantee access to the tool during repairs. To create a multifunctional machine, it is worth providing a place for mounting a milling manual machine. For the table you will need the following materials:

bar 80 by 80 mm
bar 40 by 80 mm
a piece of laminated plywood or chipboard measuring 900 by 900 mm.

First you need to measure the gap between the legs. The optimal distance is 60-70 cm. Bars for prolegs and drawers are obtained during the longitudinal sawing of bars 80 by 80 mm. The height of the legs is selected at the discretion of the master. Each end of the prolegs and the tsarg should have two holes for dowels. Similar holes should be present on the sidewalls of the legs. Next, you need to smear the dowels with glue to half and insert into the ends. After that, you can assemble the entire frame. In this case, the frame will not be disassembled.

All surfaces at the contact points must be smeared with glue. However, self-tapping screws also do not interfere. They will make the structure more durable. Holes for self-tapping screws must be prepared in advance. The lid is attached to one of the sides with hinges. A slot must be made in the cover in order to facilitate the removal and installation of the jigsaw.

In the back of the tabletop, you need to screw two strips in which a quarter is selected. It includes the sole of the jigsaw. The strips must have holes for further installation of bolts or clamping screws. As a result, you get a fairly simple and spacious table. Thick chipboard or plywood will help to achieve high strength of the cover. Sheets must be thicker than 20 mm.

A standard jigsaw saw is not designed to create complex patterns in plywood. For these purposes, a thin nail file is needed. It can be attached to a hand-held power tool using an unusual device. The jigsaw, as in the previous versions, is mounted on the countertop. But a thin nail file must be taut, a simple installation on a pendulum will not work. To facilitate the procedure for tensioning the canvas, it is worth creating a rocker from a bar. The tension of the file in this case will be provided by a spring. The lower loop of the spring must be put on the transverse pin, and the upper loop is inserted into the adjusting screw, which changes the damper tension.

Note that all wooden blanks for such machines must be created from solid wood. Since the jigsaw machine does not have the ability to fasten a thin-section blade, you can remake a piece of an old blade by pre-drilling a hole in it and equipping it with a screw with a nut, as well as a clamping plate. The rocker arm must contain a vertical slot into which the second steel plate is inserted. It is attached to the rocker with screws.

The idea of \u200b\u200bcreating a homemade electric jigsaw is most often due to the shortcomings that the factory has hand tool. You can make a small desktop machine with your own hands, which will include a pusher, a reciprocating motor, a file tension system. At the same time, you do not need complex drawings– once you understand the essence, it is easy to achieve the result.

How to make your own setup

The desire to create a homemade jigsaw may arise for several reasons:

There is no power supply in the workshop, but it is possible to use internal combustion engines low power.
There are pneumatic motors, but the compressor power is not enough for a serial tool.
The electric motor is powered by batteries or solar panels, the power of the source is not enough for the use of power tools.
It is required to obtain saw movement parameters that are unattainable when using a serial tool.

Designing a jigsaw is not difficult. A typical structure looks like this:

The unit can be easily adapted to any torque source. A pair of pulleys (one is located on the motor shaft, the other drives the crank mechanism) allow you to vary gear ratio, reducing the load on the power unit and allowing you to get desired speed(they are also responsible for the number of saw strokes per minute) on the actuator.

The machine, built according to the above scheme, can have a very different configuration, the material of manufacture is also selected individually. Example finished installation looks like this:

Disadvantages of a manual jigsaw

A manual electric jigsaw is designed to form even cuts. At the same time, as the rollers, rod, and pusher wear out, the saw may be beating and deviate from a straight line, and the angle of attack may change. Regardless of the quality of the tool assemblies, the following features are always present:

When the saw becomes blunt, a deviation from a straight line is observed when cutting material of uneven density (for example, low-quality chipboard). The saw is able to leave the cut line, having met a knot in the wood.
When trying to make a figured radius cut, one can observe the following picture: the upper cut line, followed by the worker, follows an exact trajectory, the lower one deviates, goes to the side, the radius becomes larger. The higher the wear of the tool and the lower the sharpness of the saw, the more pronounced this phenomenon.
Some materials cannot be worked with the pickup or bottom feed of the saw. The carpenter is required to drive the tool forward extremely evenly, which cannot be done very accurately, resulting in a beating of the saw along the entry and exit path.

It is even more difficult to work with thin, designed for curly cuts saws. If there is no practice, achieve good result very difficult, especially on thick slab or wood materials. Consider how you can make the work of a carpenter easier, and the result better.

Standard Solutions

The machine from a manual electric jigsaw is made on the basis of a simple table. This device is common, mass-produced, samples can be seen in the photographs below.

The mechanics of work is simple:

The jigsaw clearly fixes the tool, ensuring that there is no influence of the human factor (the hand can lead the jigsaw unevenly).
The presence of a support allows you to move the device without deviations along the trajectory.

With the help of a table, jigsaws begin to cut in a straight line, but the possibilities of such a device are limited. If you remove the side stop and try to guide the workpiece, forming a curved cut, the same problems of saw deflection arise. The problem can be solved by using a simple saw, rigidly fixed with a pair of rollers. Making curly cuts is now convenient and fast. How homemade and industrial products of this type look like is shown in the following photos.

Tensioners for curved cuts

To perform very thin and precise curly cuts, you can make a machine from an electric jigsaw with a saw blade tension system. The idea of \u200b\u200bdoing it yourself is as follows:

A very thin saw is used, ideally for a manual jigsaw.
A clamp is attached to the rod of the power tool, which will stretch the cutting blade.
The trajectory stabilization system will regulate both one freedom of movement and two (horizontal and vertical).

As a tension block, a manual jigsaw clamp is used, to which an adapter is made, which, in turn, is inserted into jig power tool rod. To ensure the adjustment of one freedom of movement, a pair of angles and a bolt are used. The result of the implementation of the idea is presented in the following photo.

The saw provides a clear vertical movement, you can create a good tension, but there is a mandatory runout in the horizontal direction. The canvas goes with pickup, it does not move in a straight line.

The development of this idea is in the next photo. Here the part fixing the trajectory moves, and the metal clamp provides structural rigidity and mechanical resistance.

The system is stabilized in two degrees of freedom, the cut made with its help is accurate and accurate. Using a diamond-coated cord for a hand jigsaw, you can cut glass without the formation of sloppy chips on the edges.

Devices for extremely fine work

If you need to work extremely delicately and slowly, you will need to reduce the force on the cutting blade and at the same time provide a strong tension and precise movement of the file. To do this, a home-made jigsaw is equipped with spacers with long arms.

In this case, the power tool does not operate in the cut zone, but at some distance. This allows, depending on the wishes of the carpenter, to adjust the force, speed and amplitude of the saw movement. One of the options for implementing the idea is presented in the following photo.

Depending on the needs of the master, the structure can be made of steel, have additional fixing zones, the power tool can not be installed rigidly, but with the possibility of movement within its support beam.

In practice, such solutions are rarely used. For fine work that are performed constantly, it is much more profitable to purchase a specialized band saw that will ensure quality and productivity.

As can be seen from the presented designs, a jigsaw can be made even from sewing machine having a moving rod.

DIY desktop jigsaw | Construction portal

A desktop jigsaw is an indispensable thing for any owner who is used to doing housework on his own. Especially electric jigsaws good for private sector residents, hobbyists manual labor and summer vacation. From its prototype, an ordinary manual jigsaw, the desktop electric model has 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.

Inside is an electric motor 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. Instruments can be with motor, foot or manual drive 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 from laminate and drywall, plastic blanks, and also for cutting sheet metal.

The desktop electric jigsaw makes clean cuts of complex shapes and works with fine 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. The large size of the table makes it stable, so that a precisely defined sawing direction is observed.

Types of jigsaws

Today, a wide variety of electric jigsaws are presented on the power tool market, which differ in the nature of the application, technical characteristics, type of power supply and design features. IN construction stores you can buy a 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 intended 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

Desktop electric jigsaw is fixed structure, so this cutting type The 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 well position 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 opportunities settings from the material and the required detail of the cut blanks.

If you need to cut small parts, 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 inconveniences are too large sizes and the complexity of working with big details.

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 base plate 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 with any accessible way. The jigsaw file remains ordinary, but the possibilities for good sawing expand due to the release of 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 that if the force is too high, the material being cut out can be caught in flames, and if it is not enough, 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 a desktop jigsaw, you must adhere to some rules:

While cutting, do not press hard on the tool, otherwise, at best, the needle will break, at worst, you will spoil the work.
Change blades from time to time. old saw can spoil and destroy the surface of the material.
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.
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.
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.
To cut different materials, appropriate blades are needed, with a special pitch and length.
Rotate the tool by turning only the back of the tool.
When cutting the laminate, an adhesive tape is glued to the cut line, which protects the material from chipping.
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 the help of an electric jigsaw, you can process large parts, wide workpieces and small products, which is not superfluous at home.

wood jigsaw

For slotted carving and sawing 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. But with the advent of the sale of manual electric jigsaws, it became possible to both install them on a table for sawing large parts, and use them as a drive for jigsaws for cutting small parts. The manual jigsaw is well balanced, powerful enough and has a speed control, which greatly expands the possibilities of its application.

Still, in my opinion, the electric jigsaw has a significant drawback, this is the inability to adjust the amplitude of the stroke of the nail file. But I dealt with this shortcoming by making a file stroke regulator.

The basis for the manufacture of the machine was taken from the version printed in Wood magazine No. 12 1986.

The dimensions of the rocker arms were chosen based on their own needs. It should be borne in mind that by increasing the length, we will increase the size of the workpiece, this is a plus. But at the same time, we will increase the vibration of the file, as well as the mass of the rocker arms, which will lead to an increase in the vibration of the entire machine, and this is a minus. Therefore, we make the length no more than necessary. An increase in the rear of the rocker arms will lead to easier file tension, but again, to an increase in mass and, accordingly, vibration. There is an opinion that by balancing the rocker relative to the swing axis, it is possible to reduce the vibration of the machine. In my opinion, this is not correct.

Vibration can be reduced by reducing the mass of the rocker arm as much as possible. But at the same time it is necessary that it remains rigid, and can withstand heavy loads.

Easy to use for stretching eccentric clamps from a bicycle. The tension of the nail file should be implemented through a rigid spring. It will help reduce the number of nail file breaks.

The attachment of the file should quickly and securely fix the files different sizes.

The slats on which the rocker arms are attached must be securely connected to each other in order to reduce vibration.

The entire structure of the machine must be rigid and reliable. Management must be in convenient location.

I will answer all your questions.

Wish you successful homemade.

With the help of a homemade jigsaw machine, anyone can make furniture, modern convenient shelves and other wood products. Its mechanism helps cut wooden details absolutely any form. And also with its help it is possible to process plastic and other dense materials. In order to jigsaw machine complied with all norms and rules, you need to carefully approach the choice of its design. Additionally, drawings from the network will help to make a jigsaw machine with your own hands.

How to make a jigsaw machine with your own hands

The design of jigsaw machines

Absolutely any electric homemade jigsaw contains the following parts:

drive unit;
connecting rod assembly;
saw;
work surface;
saw tension mechanism;
additional mechanisms.

The material to be processed should be laid on the work surface. Many models are equipped swivel mechanism, which changes the inclination of the cutting surface. In order to facilitate the application of markings on the processed material, graduation is applied to the working surface. It is worth choosing a jigsaw with a large desktop size, because it will make the longest cut. Basically, for most models of electric jigsaws, this indicator is about 35 centimeters. The optimal drive power for a do-it-yourself jigsaw machine is no more than 200 watts.

The crank assembly mechanism is able to convert the rotation of the drive into translational motion and transmits it to the saw. The optimal frequency of the saw movement per minute is about 900, and the amplitude of the vertical movement should not exceed 6 centimeters.

Many types of electric jigsaws are equipped with a speed controller, which allows you to adjust depending on the type of material. A jigsaw file is capable of processing wood and plastic up to 12 centimeters thick, with a length of up to 40 centimeters. To work with various materials, files can be changed, their width ranges from 2 to 12 millimeters. The manual tension mechanism secures the file for even cut. Its role is performed by spring or helical springs.

The main types of jigsaw machines

All electric jigsaw machines are usually divided according to the following criteria:

The most popular are electric jigsaws with a lower support, in which the bed is divided into upper and lower parts. The first contains the cleaning and cutting modules, and the second contains the electric motor, controller module, switching and transmission mechanisms. These machines can process absolutely any sheets of material.

Double caliper jigsaws have a major difference. It lies in the fact that in the upper part of the bed there is another rail. Such equipment is well suited for the manufacture of oversized products. Such devices are very easy to install and allow you to process products with a thickness of not more than 9 centimeters. Additionally, the machine comes with a convenient desktop with adjustable height and angles.

Suspended jigsaws are not equipped with a stationary frame and have great mobility. When performing work, the cutting module moves, not the material being processed. The working module itself is fixed on the ceiling on its own, which is why the size of the workpiece does not matter. The cutting mechanism moves with its own hands, regardless of the bed. In this case, it becomes possible to make a wide variety of patterns.

Electric jigsaws with stops and a degree scale are ideal for the most precise work with the help of drawings. Their design helps to avoid errors during operation. Universal type jigsaws are capable of doing several types of work. This is, first of all, cutting, grinding, polishing, drilling and many others.

How to make a jigsaw machine with your own hands

When developing a drawing of a homemade jigsaw machine, the total number of elements must be reduced to minimum quantity. A saw with a fixed rocking chair, an electric motor and a bed is enough. If desired, a motor from any electric machine is suitable. Much more fortunate are people who own a jigsaw manual type. From plywood sheet it is necessary to make a special stand and fix the jigsaw on it. To fix it, it is worth making holes in the base of the jigsaw. Thus, the simplest jigsaw machine can be considered ready.

Next, it’s worth talking about more functional and complex models of devices that you can do yourself. Homemade bed it is made from a sheet of plywood 12 millimeters thick, textolite or plastic. Such a bed is a working surface, the base of the machine and a special box for the location of various mechanisms and an electric motor.

WITH reverse side it is necessary to place an eccentric with a rocking chair, which must be connected with a metal plate with bearings and bushings. This whole structure must be fixed with screws. To install the intermediate shaft, you need to find several bearings. A special metal pulley fits quite tightly onto the shaft, and the screw connector is securely fastened. Similarly, you need to make a homemade eccentric for the device.

In order to change the frequency of movement of the rocking chair, it is necessary to make several through holes on the installed flange and cut threads into them. They must be removed from the central axis at different distances. By changing the place where the screw is screwed in, it is possible to adjust the amplitude of movement of the rocking chair, which consists of several wooden yokes attached to the rack with hinges. The ends of the rocker arms have through cuts into which tension screws are inserted. A file is attached to the other ends, moving with the help of metal hinges. For fixing, the file is installed in a special groove of the working surface.

The saw blade attachment can be considered the most important. When assembling a jigsaw machine with your own hands, this part should be given great attention. The plates inserted into the rocker arms carry a huge load during operation, which is why they need to be strengthened and tightened with fasteners with high quality. The two tie-down earrings do not need to be tightly compressed with screws, which will allow the axle hinges to move.

The rocker arm mechanism is best made from solid material. On one side, you need to make a groove for the rocker, and on the other, you need to cut a rectangular opening for the second rocker. In order to make it easier to make holes, it is worth folding the rack from several parts.

The jigsaw machine allows you to quickly and efficiently cut wood. consists of a working surface, racks, motor and spindle assembly. Some devices are made on stands. Clamps are quite often installed in the side of the work surface. It is also worth noting that the models differ in power. The manufacture of a jigsaw machine can only be carried out if the instructions are followed.

Desktop devices: expert reviews

If you believe the reviews, then making a desktop modification is very simple. First of all, a rack is prepared for the work surface. Its width should not exceed 30 cm. It is more expedient to select a motor of a single-phase type with a maximum voltage of 220 V. A home-made jigsaw machine (desktop) produces an average operating frequency of 55 Hz.

Reviews of experts say that yews are best used from steel, if desired, they can be cut out on their own. The file is mounted on a spindle assembly, which is attached to the rack. Many models use a latch that plays the role of a stop. To fix the file, a small screw is used.

Models on legs

If necessary, you can do this with your own hands. Modification drawings include frames of different sizes, and spindle assemblies are usually used with guides. Many models are made on a wide bed. Legs can be installed from tubes. There are also machines with plates. After cutting out the working platform, you should take up the spindle assembly.

If we consider devices with control units, then the model will require a controller. It is more expedient to use a motor of a collector type for 220 V. Yews are installed on jigsaw machines of a rotary type. The direction must be welded to the edge of the plate. The file in this case must be securely fixed. Optimal Height spindle assembly is 2.2 cm. At the end of the work, it is important to install power cable and equipment connection.

Feedback on devices with a wide frame

Professionals are able to assemble a jigsaw machine with their own hands. Device drawings indicate the presence of wide stops. However, first of all, you need to install the frame. If we consider a simple machine, then the latch for modification can be selected for a small length. Reviews of experts indicate that two racks are enough for the model. Used to assemble the machine welding inverter. The spindle assembly itself is installed in the central part of the working platform. The hole for the file can be made with a cutter. It is also worth noting that experts do not recommend the use of two-phase motors.

Compact modifications

Following the instructions, you can assemble a compact jigsaw machine with your own hands. Device drawings include double racks and narrow frames. Beds are applied with a low profile. Many models have a spindle assembly without a holder. In this case, the guides are set to a short length. For self assembly Models are recommended to choose a high-quality frame first.

Additionally, a clamp is soldered under the work plate. To reduce the level of vibration, you can use the lining. To fix it, ordinary glue is used. The file for modification should be selected with a small thickness. The optimal installation distance of the central node is 14 cm. At the same time, the width of the platform is on average 17 cm.

Jigsaws for 2 kW

If you wish, you can make this jigsaw machine with your own hands. Drawings for assembling modifications are very easy to find. As a rule, frames are used with a width of 35 cm or more. The thickness of the plate should be about 1.5 mm. The hole for the file must be made before installing the central node. If we consider models without stops, then the frame is used with a low profile. It is also worth noting that it is more expedient to install the spindle assembly on a lining.

A casing is used to reduce the noise level. Many models use multiple stops. In this case, the node is installed at a height of 10 cm. It is better to fix the file on the plate. Clamp can be used screw type. After fixing the central node, the motor is placed. For modification of this type, a device with a single-phase unit is suitable.

Models for 3 kW

At 3 kW, a do-it-yourself desktop jigsaw is quite simple to make. Experts recommend using racks with wide stops. Fasteners need to be installed only after the central node. The file for modification can be picked up by 1.2 mm. Some experts make a hole after installing the frame. In this case, the supports are soldered on the sides of the table.

Next, it is important to evaluate the size of the spindle. It is more expedient to use the motor with a protection system and a casing. It is also worth noting that collector devices that operate at a frequency of 45 Hz are very popular. They have low energy consumption and do not overheat. Holders are used to fix workpieces. The optimum spindle height is 15 cm. It is also worth noting that there are models with tuning plates. A flywheel is used to control the rack. To install the control unit, there is a conventional controller.

How to make a 5 kW device

Having prepared a few stops and you can make a jigsaw machine with your own hands. Expert reviews indicate that 5 kW models are well suited for ripping. Before starting work, all the necessary tools are prepared. You will need a saw as well welding machine and cutter. It is more expedient to assemble a frame for a jigsaw machine from steel plates with a thickness of 1.3 mm or more. For the motor, you need to immediately provide a place. The beds in the devices are installed with a high profile.

At this stage, you can immediately cut a hole for the file. The plug assembly must be mounted on the top of the plate. Additionally, it is worth noting that the file will require a large holder. If we consider a simple model, then the racks can be installed on the sides of the frame. Yews are used rotary type. At the top of the frame must be a rack. A small casing is selected under the motor. On average, the frame width should be 35 cm. If we consider professional models, then they use adjustable clamps.

Modifications for two quills

How to make a jigsaw machine with your own hands? The model with two quills is assembled only on a wide frame. First of all, plates are cut out under the bed. If we consider a desktop modification, then it is more expedient to install the control unit at the top of the device. The optimal frame width is 45 cm. In this case, the spindle assembly is installed behind the stops.

Must be provided for racks. Many models use transfer blocks. In this case, the motors are suitable only for a collector type with a frequency of 30 Hz or more. The file is installed as standard in the holder. The optimal height of the spindle unit for models is 35 cm. Quills for adjusting the bed are used with flywheels.

Models for three quills

On the basis of a single-phase motor, it is easy to do this one with your own hands. Tools should be prepared in advance. Many models are equipped with frames for four stops. They are long and high profile. It is also worth noting that the spindle units are selected with. At the beginning of work, it is very important to calculate the length of the frame. If we consider ordinary spindle assemblies, then the rack for them is prepared for a short length.

The central support must withstand heavy loads. A welding inverter is used to install the plates. The motor will require a casing that will significantly reduce the noise level of the device. A saw for modifications of this type is suitable for 1.2 mm. With a power of 3 kW, a device for three quills will produce a frequency of 55 Hz. Brackets are needed to fix the flywheels.

For slotted carving and cutting out small parts from wood, plywood, plexiglass, plastics and other materials, jigsaws of various designs and types are used. 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.

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

The drive power for a 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.

A manual jigsaw file 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 materials and works of the file vary, 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. The 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 homemade desktop jigsaw: 1 - rocker 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 - axis of the rocker, 12 - lamb, 13 - cross member of the tension screw (2 pcs), 14 - tension screw, 15 - rocking stand, 16 - lower rocker, 17 - box, 18 - two-strand pulley, 19 - intermediate shaft, 20 - stand 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 rocking chair, four round ones are made on the eccentric flange. through holes with threads, 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.
