Desktop jigsaw do-it-yourself drawings. Desktop jigsaw: description, characteristics Do-it-yourself jigsaw machine

A jigsaw machine is a high-precision equipment designed for processing workpieces of varying complexity, made of different materials. To choose the right device, you need to study its design and familiarize yourself with some useful recommendations.

Mostly jigsaw machine einhell, like its competitors, are used for the following purposes:

• Processing of complex contours from blanks;
• Cuts on the inner surfaces of the material, without affecting the outer contours;
• Furniture manufacturing;
• Production musical instruments;
• Creation of all kinds of blanks based on wood.

In addition to wood, even an assembled do-it-yourself jigsaw machine is able to work on plastic, ceramics, plexiglass, polycarbonate and a number of other materials. But still, the main material that jigsaws have to deal with is wood. Makita machines do an excellent job with this task.

Design

Studying the wmss 11 01 jigsaw kraton machine or its competitors represented by Makita, Bosch, Excalibur in order to assemble such a device with your own hands, we can say that structurally they all look about the same.

If you decide to make a homemade jigsaw machine, equip it with a CNC module in the future, then it is better to start manufacturing by studying the design of factory models.

The main structural elements of the machine are:

• Desktop;
• Electric drive;
• KShM (crank mechanism);
• Sawing tool;
• Tension mechanism;
• Auxiliary elements;
• CNC module.

If we take for example such machines as Makita, Proxxon, Dewalt, Hegner, Holzstar, Excalibur, DKS 502 Vario, Dremel or WMSS 11 03, they will be structurally close to each other. But estimated price- from 6-10 thousand rubles. Therefore, the choice must be based on technical parameters and your personal needs.

1. The working table is used to place the workpieces to be processed. A number of machines are offered with rotary mechanisms for the table, which allows the operator to change the angle of inclination as needed, to perform inclined processing of parts. When performing a homemade jigsaw, you should think about grading to simplify marking. The size of the workpiece with which you can work depends on the size of the table. Therefore, base the choice on what materials you have to deal with. A standard table has a length limit of up to 30-40 cm.
2. The drive differs in power. Manufacturers such as Makita, Hegner, Dremel, Dewalt, WMSS 11 03, Proxxon, Holzstar, Excalibur, DKS 502 Vario offer a wide range of machines, each of which has different drive powers, nuances of the CNC module, etc.
3. KShM. This mechanism transfers the torque from the electric drive to the saw of the machine. The vertical movement of the file can be 3-5 mm at a speed of up to 1000 oscillations per 1 minute. Some machines, including Makita, Excalibur, WMSS 11 03, Dremel, Dewalt, Hegner, Holzstar, DKS 502 Vario, are equipped with a sawing frequency adjustment function. This allows you to adapt the machine to the specific type of material being cut.
4. File. With a length of 20-35 cm, it is able to cut a workpiece with a thickness of 10 cm. Saws differ in size and materials of manufacture. The choice is based on the density and characteristics of the materials to be cut.
5. Tension device. Due to it, the file receives the necessary tension at working points. Depending on the model, the device is based on springs or springs.
6. Auxiliary elements are primarily a dust extractor. If you decide to make a homemade jigsaw machine, we recommend that you provide this functionality. It can be organized using a conventional vacuum cleaner.

An ordinary electric jigsaw is sometimes quite capable of replacing a jigsaw-type machine. The jigsaw is not a stationary unit, but hand tool. At the same time, the jigsaw has a wide range of applications. For domestic needs, it can be enough with the head. If, however, for work in a workshop, garage or in production, maximum cutting accuracy is required, then instead of a jigsaw it is better to purchase a full-fledged machine. Better yet, CNC. The CNC module will provide process automation. Through the CNC, the necessary programs are set, the machine independently processes the workpieces according to the specified algorithm.

A jigsaw cannot have a CNC, since it belongs to the category hand power tools. A stationary unit is in many ways better, because often the choice falls in its direction. This is evidenced by numerous customer reviews of Makita, Proxxon, Dremel, Hegner, Dewalt, Excalibur, Holzstar, WMSS 11 03, DKS 502 Vario, etc.

Criterias of choice

When such machines as Makita, Dremel, Holzstar, Dewalt, Proxxon, Hegner, DKS 502 Vario, WMSS 11 03 are on the market, the choice is complicated by the wide range. To make your choice a bit easier, think carefully about your machine requirements.

Based on them, you can understand whether the scheppach deco flex jigsaw is right for you, or maybe even prefer a homemade jigsaw.

1. Power. Dewalt, Hegner, Makita, Proxxon, Dremel, WMSS 11 03 equipment is offered in various designs - from household to professional. The choice in favor of professional devices with modern CNC should be done by specialists who regularly operate the equipment. The power of such devices is from 1 kW. The power parameters of household models from Dewalt, Proxxon, Makita, Hegner, Dremel are in the range of 500-950 watts. Power affects the depth of cut and the duration of non-stop operation. You should choose a more powerful model even for domestic use because they have a margin of durability.
2. The weight. The more powerful the selected Dremel, Dewalt, Makita, Proxxon, Hegner or WMSS 11 03 unit is, the more weight it will have. Since this is not a hand tool, it is important to take weighty devices. They generate less vibration, providing required quality processing.
3. Speed. Here the speed is measured in strokes per minute. Most machine tools from Makita, Proxxon, Hegner, Dremel firms, the frequency is in the range of 0-3500 units. Industrial models provide increased travel speeds for high precision machining.
4. Personal feelings. When choosing a machine, be sure to try it out. So you will understand how comfortable it will be to deal with him.
5. Stroke frequency adjustment. Modern machines Dremel, Proxxon, Makita, Hegner, Dewalt necessarily include the possibility of adjustment in the list of available functions. Only the range of adjustments for each model is different. Rely on the materials to be cut. The more diverse the blanks are planned, the wider the range of settings. In this regard, CNC models are convenient. They are adjusted to a specific material, which allows you to practically not take part in operations during the cut. This is the main advantage of CNC, for which many are willing to pay a lot of money.

Before you make a jigsaw machine with your own hands, based on drawings and videos, or purchase Makita products, Proxxon or WMSS 11 03, think carefully about your actions.

Homemade units are good in places, but they are far from the level of Makita machines. Makita has a very good reputation. Many aggregates from Makita receive numerous positive reviews, laudatory criticism from experts. Yes, in addition to Makit, there are a number of other companies on the market that we talked about.

You choose whether it will be a machine from Makita, or decide to cut blanks on Proxxon, Bosch machines. For some, it’s even easier to make a device with your own hands than to pay for, of course, a high-quality Makita product.

Many years ago, while studying in the aircraft modeling circle at the House of Pioneers, I first learned such an interesting tool as a jigsaw. It was an ordinary steel arc with a handle. At the ends of this arc, a thin strip with teeth, a file, was clamped. With this uncomplicated tool, a lot of ribs and frames for future aircraft models were cut out.
Time has passed, the era of universal joy of owning any instrument has come.
The screwdriver has already been forgotten, because there is a cordless screwdriver.
Already few people saw trees with a two-handled saw, among the people "friendship-2". What for? After all, there is a chainsaw.
The hand planer has not yet been forgotten, but is no longer as popular as it used to be. There is e. planer, planer, planer.
But a manual jigsaw, the so-called pioneer, is still no, no, and will appear in the hands of a craftsman. To cut a unique delicate pattern, it has no equal.
But for many years, craftsmen in many countries of the world have been using a jigsaw.
Back in the late 60s and early 70s, my parents annually subscribed to me such magazines as "Modeler-Constructor", "Young Technician", "Appendix to For young technician", "Science and life".
And in one of the issues of some magazine, I first saw drawings of a jigsaw machine from an old sewing machine. But I abandoned aircraft modeling, delved into the radio circle, and, in principle, then I didn’t need a jigsaw and I let these drawings pass me by.
Years have passed, attitudes and preferences have changed.
And now a house, a workshop has been built. And the beauty of cut wood or plywood haunts me.
On the Internet, I dug up very interesting, cut out of plywood, works of almost art.
I even started to cut something with a pioneer jigsaw. But it is so dreary and not productive that I thought about a jigsaw machine.
And then I was faced with a choice, although not in in large numbers, but still.
The machine itself is multi-layered.
According to my requirements it should have:
- No vibration
- Clamps for flat and pinned files,
- Smooth adjustment of the number of revolutions of the crankshaft flywheel,
- Good and reliable blowing of the cut,
- backlight,
- A working table that does not bend and does not stain the part,
- Large stroke of the file,
- Control of the machine with a pedal,
- Asynchronous motor, because the collector is very noisy,
- Long time of continuous work,
- Reliable upper clamp of the file after numerous rearrangements. On average, in terms of the complexity of the product, the file must be disconnected and again clamped up to 1000 times per product.
- No complex maintenance. So that the wife can work on it.
- low price
The last paragraph made me smile. Machines are on sale from 2 to 50 thousand rubles.
And the cheaper the machine, the more time it needs to be given before work. Tuning, fitting, and sometimes turning new parts and replacing bearings.
This is the task I "puzzled" myself.

For curly cutting on wood, a hand-held jigsaw was traditionally used - a simple tool with a thin file that allows you to create elegant patterns from wood. Later, a jigsaw was invented, working on muscle traction like a foot sewing machine or potter's wheel.

The development of technology and the emergence of compact electric motors of low power led to the creation manual jigsaw, and then the corresponding electrified machine, which you can make with your own hands.

Purpose

Stationary units that ensure the movement of the saw blade vertically make it possible to cut parts of complex shape from sheet materials, elements with curved edges. If you insert a file into a through hole drilled in the workpiece, you can make a curly contour inside the product.

With the help of jigsaw machines, workpieces from various sheet materials are processed, including:

• solid wood;
• plywood;
• wood-based boards (chipboard, fiberboard, MDF);
• aluminum;
• plastic.

With the help of a jigsaw machine, it will be possible to increase labor productivity and significantly improve the quality of processing curly edges of products. This is due to the fact that a working person has both hands free and he can position the workpiece as accurately as possible relative to the moving cutting blade. This is the main advantage of a stationary tool with an electric drive from a manual jigsaw.

Jigsaw machines are installed in school and home workshops, also this species equipment is used in furniture production and in the manufacture of musical instruments. Modern laser machines can be used instead of jigsaws, because they provide highest precision cutting along a given contour, but their use limits the effect of burnt ends of parts.

Device

The desktop jigsaw machine consists of the following elements:

• frame (support structure on which all mechanisms and components are mounted);
• Desktop;
• electric drive;
• crank mechanism (responsible for converting the rotation of the motor shaft into the reciprocating movement of the file);
• double rocker (equipped with clamps for files and a tensioning mechanism).

The machines produced today are mostly designed for the use of files with a length of 200-350 mm and a working stroke of 30-50 mm. Files differ in width (2-10 mm), thickness (0.6-1.25 mm) and type of shanks - they come with pins and without pins. The latter are more convenient, since in order to cut the inner contour, it is necessary to drill a hole in the workpiece through which the end of the file must pass. If there is a pin, the hole should be noticeably larger. Some models of jigsaws allow you to mount files of both types, including the old model, from a Soviet hand tool. Files also differ in the size of the teeth and their arrangement - it can be straight or spiral.

Tool selection

To choose a good machine suitable for the solution specific tasks, it is necessary to pay attention to its power. The main part of the models is equipped with an electric drive with a power of 90 to 500 watts. For home use the optimal power is 150-200 watts.

An important selection criterion is the presence of two speeds of the unit. AT standard version- 600 and 1000 rpm. This makes it possible to select the appropriate mode for working with materials of various densities.

The desktop is fixed and swivel. Fixing the table at an inclination allows cutting material at specified angles other than 90°. There are also models that have adjustable table height - this allows you to extend service life files, since you can use different sections of it for work along the entire length, and not just the central part.

Manufacturers equip jigsaws with a variety of options, including:

• a compressor for removing chips from the marking line with an air jet;
• drilling unit;
• backlit working area;
• blade fencing (will not allow fingers to contact with a moving file);
• clamping device (prevents vibration of thin sheet material).

Additional options increase the cost of the jigsaw, but do not fundamentally affect its functionality.

Manufacturers

There are various types of jigsaws on the market for power tools: from devices designed for creative work at home to high-performance models designed for professional use. In addition to machines that use conventional files, you can find band saws on sale.

The list of popular brands includes Bosch, Negner, Einhell, Proxxon, Makita, DeWALT, JET, Xendoll, Excalibur, Kroton, Korvet, Zubr.

The leader in quality and reliability is the products of well-known German brands Bosch, Einhell and Hegner. In addition, the lines of jigsaw machines include a wide range of models of various capacities and configurations, which makes it possible to choose a quality electric jigsaw for the home, optimal in functionality.

Budget models, including those made in China, have also proven themselves well. Models of the brand Korvet, Zubr and others are suitable for home use without increased loads.

Before buying a jigsaw machine, regardless of its brand, it is imperative to conduct tests to assess the smoothness of the working body and the noise level, to make sure that there are no extraneous sounds and vibrations. It is recommended to compare several models of different brands and purchase the option with the best performance.

Making a jigsaw with your own hands

A home-made machine, made to replace a conventional wood jigsaw, is able to provide high-quality performance of the main set of operations for curly cutting sheet materials. Depending on the purpose, it is possible to design a compact electric model or a stationary unit designed for high loads.

materials

As a basic scheme, it is most convenient to use a drawing of a simple wooden jigsaw with a flywheel and a pedal assembly and replace the mechanical drive with an electric one. If the machine is intended to be used only occasionally, a special electric motor can be dispensed with. Instead, connect any suitable power tool. It is convenient to use a screwdriver with adjustable speed.

The material for the manufacture of the machine itself is wood, while:

• the bed and the supporting pedestal for the lever bar are best made of high-strength plywood (minimum thickness - 18 mm);
• for a lever structure, it is necessary to take dense wood that is not prone to cracking under load - this is beech or oak (instead of buying bars, you can use straight legs of old chairs that are suitable in size);
• for the crank mechanism, plywood 10-12 mm thick is required;
• for the rest of the structural elements, pine lumber, various trimmings are suitable.

According to the scheme of the jigsaw machine, a bed and a supporting pedestal are made. As fasteners, use wood screws, joints wooden elements structures are recommended to be coated with PVA emulsion. It is important that the design is strong and there is no play, otherwise the accuracy of the machine will be low.

Part preparation and assembly

Next, the levers of the desired length are cut out, cuts are made at their ends for fastening the file. The mount is made of a steel plate 2-3 mm thick, with a pair of holes. The upper hole allows you to fix the plate on the lever, and the lower one is designed to attach the saw shank. Fasteners - screws of suitable diameter and nuts - it is more convenient to use wing-type. Mounting on the lower arm is installed in the same way.

At the next stage lever system mounted on a stand. To connect the free ends of the levers, a screw tie (lanyard) is used, which makes it possible to easily adjust the tension of the saw blade.

Note! The length of the files used should be determined in advance, since the size of the lever mechanism depends on this. It is necessary to ensure the maximum possible parallelism of the levers relative to each other.

Racks need to be fastened together to create a solid support for the flywheel. The axis can be a stud or a bolt of at least 8 strength class. The flywheel with the lower lever is fastened by means of a connecting rod made of the same plywood, while the rods connecting to the lever must be metal.

At the next stage, a desktop is made with swivel mechanism- it is necessary to cut a rotary arc with a slot from plywood. The table is placed on the bed. To easily fix the swivel mechanism in the desired position, use a wing nut.

In this model, a screwdriver serves as an electric drive - for work it is enough to connect its cartridge with the flywheel axis. You can adjust the speed using a clamp with variable force, made of a strong strap and a small clamp (or other screw tightening).

Simple in design homemade machine convenient to work.

Rugged fixed construction

The design of a jigsaw for professional use is practically the same as a compact wooden model. It is only important to choose the right materials so that the unit is able to withstand increased loads and does not vibrate during operation.

• bed - heavy chipboard;
• rack for lever construction - hardboard, textolite of suitable thickness;
• levers - steel square pipe;
• countertop - any durable, hard and smooth material.

Elements for fastening the blade (you can take it from an old hacksaw) are soldered to the levers or fixed with screws.

You will need a serviceable electric drive with a gearbox that will provide the necessary torque. To start the engine of a homemade jigsaw machine, it is convenient to provide a foot pedal (take it from an old electric sewing machine or make it using any suitable electric button).

When assembling the structure, metal racks and metal fasteners are used. With the help of a metal insert, you can strengthen the fastening of the connecting rod. This will reduce vibration and reduce wear.

The tabletop has a long working slot for the possibility of rotation around the longitudinal axis.

A spring is provided to tension the web. The lower lever is responsible for the movement of the working blade, the upper one helps to keep the file in a vertical position.

Thus, an electric jigsaw can be assembled on its own using scrap materials. This will not require serious financial costs, but only takes certain time to search for materials, necessary parts and assembly.

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 for the jigsaw machine to comply 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.

The design of jigsaw machines

Absolutely any electric homemade jigsaw contains these 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 with a rotary mechanism that 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 machine with big size desktop, 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.

Connecting rod 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 on the following grounds:

The most popular are electric jigsaw bottom support machines, in which the frame 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.

Jigsaws with double support 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.

Hanging jigsaws are not equipped with a stationary bed 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 degree scale ideal for the most precise work with 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 tool the total number of elements should be reduced to the minimum number. 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 manual jigsaw. It is necessary to make a special stand from a plywood sheet and fix a 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 is being made from a sheet of plywood with a thickness of 12 millimeters, textolite or plastic. Such a bed is a work surface, the base of the machine and a special box for the location various mechanisms and electric motor.

On the 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 the rocking chair, on the installed flange, it is necessary to make several through holes 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.

Blade fixing device 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.

Rocking rack mechanism 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.

Without a jigsaw, many woodworking operations are impossible. Compact and lightweight, it allows you to manufacture products of even the most complex geometries. Sometimes, for example, with large amounts of work, it is more convenient to work with this tool not as a manual jigsaw, but in the format of a machine tool. Such equipment is presented in the catalogs of many manufacturers of household power tools, but if necessary, it can be made independently.

Equipment selection - main points

To begin with, it is worth answering the question: with what material will the master work most often? Motor power of 50-90 watts is sufficient for most types of wood, but if you are going to process hard wood and significant volumes, look for options in 120 watts. Stepwise adjustment of engine speed ( saw blade speed) is desirable, choose models with a smooth change in this parameter.

The ability to adjust the speed is needed to adapt the machine to work with different types of wood - heating of the material is excluded, which will spoil the cut. In addition, by gradually increasing the speed, the master concentrates on a complex procedure, and the engine also operates in a gentle mode, which increases its resource.

Some models provide for the possibility of cutting not only in a horizontal surface, but also at an angle, and a special scale will allow you to choose the most accurate position of the workpiece. Semi-professional and household machines allow you to change the tilt of the desktop up to 45 ° in one direction, professional - up to 45 ° in both directions.

Pay attention to the work surface. It should be massive enough so as not to sag under heavy workpieces, very smooth (so the part slides on the base without problems) and polished so as not to stain the workpiece.

When choosing equipment, it is important to remember the nominal number of revolutions. Many masters mistakenly believe that it should correspond to at least 1650 reciprocating movements of the file in 60 seconds - only with this indicator the cut will be perfectly even, without chips and notches. However, modern table-top machines from well-known manufacturers guarantee a perfect cutting line even at speeds of 700-1400 strokes per minute.

Do not forget about the maximum stroke of the saw blade - the thickness of the workpieces depends on this value. Additional options are also important:

• the presence of an engraver - add. shaft for particularly precise cuts and the manufacture of fine crafts;
• removal of wood dust and shavings from the work surface;
• illumination of the cutting zone.

How to navigate in models from different manufacturers?

On the modern market there are many models of jigsaw machines, but there are several main "players", and each of them has its own characteristics, advantages and disadvantages.

Enkor's Corvette models are household-class machines and are not suitable for industrial use, but they are quite functional equipment equipped with a swivel worktop to perform an oblique cut at the desired angle, a fixed stop with a degree scale.

Although the machines of this model are not designed for processing massive workpieces, the manufacturer offers a 150 W drive. The motor is a collector type, quite noisy and prone to overheating, unable to work without interruption and requiring regular replacement of brushes.

The amplitude of the saw stroke is 40 mm, the oscillation frequency is 700 per 60 seconds (in some modifications, a second speed has been added - 1400 per minute for selection optimal mode when processing wood of different hardness). The files supplied with the equipment are not of impeccable quality, so it makes sense to immediately change them to analogues from a third-party manufacturer.

To household machines also include the Bison models, which are compact enough even for use in a city apartment. The main feature of this equipment, which can be called its disadvantage, is a noticeable vibration, which interferes with the implementation of a high-precision cut.

Zubr machines are capable of processing plywood, solid wood, plastic, thin aluminum in a horizontal plane and at an angle. They also perform drilling, grinding and polishing; for this, an additional desktop and a flexible shaft with a chuck are provided in the delivery set.

Overheating of the cutting tool is prevented by the built-in cooling system, there is an electromagnetic switch to prevent accidental switching on. Files in Zubr machines are used special, reinforced, having pins at their ends.

The working surface is fenced off from the operator by a transparent casing to protect it from dust and chips, and the cutting area is cleared of sawing products by blowing to improve visibility. Efficient waste disposal is provided. The motor used is a collector type, sufficiently resistant to overloads. Its brushes are designed for long-term operation, but their quick replacement in the equipment is still provided.

For creative carpentry workshops RSW jigsaws are designed. Among their features are the minimum backlash and the most accurate trajectory of the cutting tool. The equipment provides everything for the efficient work of the operator: fencing and illumination of the working area, the ability to remove sawn products with a conventional vacuum cleaner.

In RSW machines, the file has an unusual arrangement - with the teeth down, pin files are used, they are replaced without a key. Also among the features of the equipment is the presence of the most powerful engine in the category of similar professional machine tools.

For craft workshops, art studios and serious hobbies, JSS jigsaws from the JET brand are designed. They provide a stable cutting angle, the speed of the cutting tool is changed steplessly by the built-in electronic system.

The manufacturer offers its own branded pin-mounted files, but JSS JET equipment is also able to work with “ordinary” ones. These machines are suitable for sawing complex shapes, but the workpieces to be processed should not be unnecessarily large. Their material is wood, chipboard, plywood, fiberboard, hard and soft plastics.

The blade tension lever is located in the upper part of the machine, which increases the convenience of working with it, and the cutting blade is installed in two versions - across and along the longitudinal axis of the equipment. Dust and sawdust are easily removed by an adjustable nozzle connected to the dust extraction system. The working table can be installed at an angle, to control the accuracy of its location there is a transport scale and a stopper.

How to build a jigsaw machine on your own?

Such equipment can be made at home with your own hands, craftsmen even create such machines from old sewing machines. If you have certain skills, the drawing and design scheme are developed independently.

As a table, you can use a countertop, a workbench, and if they are not there - homemade design from laminated plywood with a minimum thickness of 10 mm. A kind of table should be built from it with a working surface size of about 500x500 mm and a leg height of about 400-500 mm. They can be two or three solid or four separate. In the first case, the design resembles a box, in the second - a traditional table on a reduced scale).

The necessary parts are sawn with a hacksaw for wood or circular saw, in a single system, individual elements are fastened with self-tapping screws. In the table lid, drill holes for fastening the tool and for the saw blade with a drill. In the sole of the jigsaw, you will also have to make mounting holes. After that, you can attach it with bolts to the tabletop so that the cutting part is brought out vertically upwards.

The advantage of such a home-made jigsaw machine is a clear fixation of the tool and a guarantee that the master's hand will lead the cut along the desired path.

A similar version of the machine does not always form the correct curvilinear cut - the file can deviate, especially if a massive workpiece is processed. The problem is solved by rigid fixation of the cutting tool with a pair of rollers that need to be placed on an additional part.

It is made from bars with a cross section of about 50x50 mm. which are connected into an L-shaped element using a furniture corner and self-tapping screws, attached to the desktop, and at the free end a bent metal plate with rollers made of bolts and bearing parts is placed with rigid fixation.

What to do if curly and very precise cuts are needed?

To perform the most accurate, very thin curly cuts, a home-made jigsaw machine must be equipped with a cutting blade tension system. Features of this device include:

• the fork should be used very thin - for manual jigsaws;
• stock electric tool must be attached to the clamp, pulling saw blade, using a special adapter;
• as a tension block, use a conventional clamp manual jigsaw.

In constructive terms, the machine differs little from that described above. It is necessary to build a work table with a hole for cutting tool and attach a clamp to the tabletop, and place the electric drive from below.

If cuts are needed especially precise and thin, which implies extremely delicate and slow work, it is necessary to reduce the force on the files while ensuring strong tension and precise movement. To this end, a home-made machine must be equipped with spacers on long arms instead of the traditional clamp of a manual jigsaw.

The spacer structure and shoulders holding the file are made of wood or steel. Otherwise, the design of the machine resembles a model with a manual clamp.
