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 volumes of work, it is more convenient to work with this tool not as a manual jigsaw, but in a machine format. Such equipment is presented in the catalogs of many manufacturers. household power tools, but if necessary, you can make it yourself.
Selection of equipment - main points
First, it’s worth answering the question: what material will the master most often work with? An electric motor power of 50-90 W is sufficient for most types of wood, but if you plan to process hard wood and significant volumes, pay attention to the 120 W options. Stepwise adjustment of engine speed (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, which will ruin the cut, is eliminated. In addition, by gradually increasing the speed, the master concentrates on a complex procedure, and the engine operates in a gentle mode, which increases its service life.
Some models provide the ability to cut not only in a horizontal surface, but also at an angle, and a special scale will allow you to select 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 ones - up to 45° in both directions.
Pay attention to work surface. It should be massive enough so as not to sag under heavy workpieces, very smooth (so the part slides over 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 craftsmen mistakenly believe that it must correspond to at least 1650 reciprocating movements of the saw in 60 seconds - only with this indicator the cut will be perfectly smooth, without chips or nicks. However, modern tabletop machines from famous manufacturers guarantee an ideal 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 workpiece depends on this value. Additional options are also important:
- Availability of engraver – extra. shaft for particularly precise cuts and the manufacture of fine crafts;
- removing wood dust and shavings from the working surface;
- illumination of the cutting area.
How to navigate models from different manufacturers?
On 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.
Corvette models from the Encore company are machines household class and for use in industrial conditions are not suitable, but this is quite functional equipment, equipped with a rotating worktop for performing an inclined cut at the desired angle, fixed by a 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 commutator type, quite noisy and prone to overheating, unable to work without interruption and requiring regular brush replacement.
The amplitude of the saw stroke is 40 mm, the oscillation frequency is 700 per 60 seconds (in some modifications a second speed is added - 1400 per minute for selection optimal mode when processing wood of different hardnesses). The files supplied with the equipment are not of impeccable quality, so it makes sense to immediately replace them with analogues from a third-party manufacturer.
Household machines also include Zubr 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 noticeable vibration, which interferes with high-precision cutting.
Zubr machines are capable of processing plywood, solid wood, plastic, and thin aluminum in a horizontal plane and at an angle. They also perform drilling, grinding and polishing; for this purpose, the delivery set includes an additional work table and a flexible shaft with a chuck.
Overheating of the cutting tool is prevented by the built-in cooling system; there is an electromagnetic switch to prevent accidental activation. The files used in Zubr machines are special, reinforced, and have pins at their ends.
The working surface is separated 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 commutator type, quite resistant to overloads. Its brushes are designed for long-term use, but their quick replacement is still provided in the equipment.
RSW jigsaws are designed for creative carpentry workshops. Among their features are minimal backlash and the most accurate trajectory of the cutting tool. The equipment provides everything for efficient work operator: fencing and lighting working area, the ability to remove sawing products using a conventional vacuum cleaner.
In RSW machines, the file has an unusual arrangement - with the teeth down, pin files are used, and they can be 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 machines.
JSS jigsaw machines from the JET brand are intended for craft workshops, art studios and serious hobbies. They provide a stable cutting angle, the speed of movement of the cutting tool is infinitely variable by the built-in electronic system.
The manufacturer offers its branded files with pin fastening, but JSS JET equipment can also work with “regular” ones. These machines are suitable for sawing complex shapes, but the workpieces being processed should not be too large. Their materials are 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 with an adjustable nozzle connected to the dust extraction system. The work table can be installed at an angle; to control the accuracy of its position, 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 They even create such machines from old sewing machines. If you have certain skills, the drawing and design diagram are developed independently.
As a table you can use a tabletop, a workbench, and if they are not there - homemade design made of laminated plywood with a minimum thickness of 10 mm. From it you should build a kind of table with a working surface size of about 500x500 mm and a height of legs 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 - traditional table on a reduced scale).
The necessary parts are cut out with a hacksaw or circular saw, into a single system individual elements fastened with self-tapping screws. In the table cover, you should use a drill to drill holes for fastening the tool and for the file. You will also have to make mounting holes in the sole of the jigsaw. After this, you can bolt it to the tabletop so that cutting part was brought vertically upward.
The advantage of such a homemade jigsaw machine is the clear fixation of the tool and the guarantee that the master’s hand will lead the cut along the desired path.
This version of the machine does not always form the correct curved cut - the file can deviate, especially if a massive workpiece is being processed. The problem is solved by rigidly fixing 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 work table, 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 you need curly and very precise cuts?
To perform extremely precise, very fine figured cuts a homemade jigsaw machine must be equipped with a cutting blade tension system. Among the features of this device:
- the fork should be used very thin - for hand jigsaws;
- the rod of the electric tool must be connected to a clamp that tensions saw blade, using a special adapter;
- As a tension block, use the clamp of a regular hand jigsaw.
In terms of design, 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 an electric drive underneath.
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 simultaneously ensuring strong tension and precise movement. For this purpose, a homemade machine should be equipped with spacer devices on long arms instead of the traditional clamp of a manual jigsaw.
The spacer structure and the arms holding the file are made of wood or steel. Otherwise, the design of the machine resembles a model with a manual clamp.
The article will primarily be useful to those people who often work with wood as a hobby, without making money from it. The author presents quite budget project desktop jigsaw, which can be assembled in one day, with minimum costs for materials.
To create the machine you will need the following materials:
- Worker manual jigsaw;
- Plywood;
- Self-tapping screws and bolts with nuts;
- Guides for furniture drawers;
- Two bearings;
- Compression spring;
- Spray paint;
- Self-adhesive paper.
Materials and tools are standard, available in every workshop.
Step 1. Body.
The first step is to create a body for a manual jigsaw from plywood. Here you need to think in advance where the holes for the switch and speed controller will be located.
It should look something like this:
Step 2. Tabletop.
It is better to take a thick piece of chipboard with good coverage, since the workpieces being processed will rub against it during operation of the machine.
A hole for a saw blade is drilled in the chipboard. The jigsaw itself will be attached to the back of the tabletop.
A stem for attaching the boom is also made from furniture guides:
Here's what it looks like assembled:
And the tabletop is attached to the body:
Step 3. Arrow.
The boom itself will be made of two furniture guides. They are bolted together to increase rigidity.
The boom supports are made of chipboard. Before painting and installing them, the point at which the boom is attached to the support is measured. Before doing this, they need to be installed in their place:
After this, it is necessary to drill holes in the support for the bearing seats.
Step 4. Painting.
The prepared supports are spray painted.
While they dry, the machine itself is covered with self-adhesive tape.
Step 5. Assembly.
Bearings are inserted into the supports and screwed into place.
The boom mounting axis will be made of two bolts screwed into the guides as shown in the photo. The diameter of the bolts is selected in accordance with the diameter of the inner race of the bearing.
The bolts are tightened securely, after which the two halves are screwed to each other.
This clearly shows how the boom will be secured in the supports:
The boom is installed in its place and secured with nuts.
Next you need to install the garter spring. It is necessary in order to return the arrow to its original position after the jigsaw pulls it down. This is how the saw will move back and forth. It must be adjusted so that it is not too soft (this will complicate the operation of the machine) and too hard (this can lead to overheating of the jigsaw motor).
How to secure it is shown in the photo:
Then, from a thin strip of metal (1 mm), it is necessary to make fastenings for the file to the arrow. They must rotate freely on the axis, since during operation the boom changes its angle of inclination to the jigsaw, and if they are static, this can lead to breakage of the saw.
This is what the mounts should look like:
The boom supports are additionally reinforced with a long bolt, it can be seen in the photo:
Step 6. Electronic part.
Since access to a manual jigsaw is limited, it is necessary to place the controls on the outside of the body.
To adjust the rotation speed of the jigsaw electric motor, the author used a phase power regulator. Here is its electrical diagram:
Here's what it looks like:
When installing the board to the semistor, it is necessary to screw the radiator; if this is not done, it may overheat and fail.
The jigsaw is disassembled and the power regulator is connected to electrical diagram.
It is also necessary to install a power button for the machine.

Tabletop jigsaw machine - equipment for cutting, sawing out shaped parts from various materials. Its feature is the ability to make cuts while maintaining the integrity of the outer contour of the workpiece. Depending on which saw is installed on the structure, the machine can process natural wood, its derivatives, plastic bases or metal.
The device is indispensable when performing construction and repair work, production of furniture, souvenirs. Equipment is often purchased for domestic purposes. Sometimes it is irrational to buy a factory unit: you can make a jigsaw yourself. The photo shows the design of the tool.
Device and principle of operation
A stationary factory sample includes a work table for a jigsaw, a unit with a cutting element is fixed on it, an electric drive installed under the table top and a crank mechanism. The tension unit is installed at the top or bottom of the machine. Many models of units allow you to cut material under different angles. This is necessary for making bevel cuts. Often, for convenience, markings are applied to the rotating mechanism, stops, and guides. The length of the cut depends on the dimensions of the table; in most models it is 30–40 cm.
Power electric jigsaw may be small. For domestic purposes, a 150 W unit is sufficient.
An important element is the crank mechanism. It is responsible for the quality of transmission of engine torque into the translational and reciprocal motion performed by the cutting element in a vertical position.
Standard jigsaw tool characterized by an oscillation frequency of up to 1000 per minute with an amplitude of 3–5 cm. Some samples provide for adjustment of the processing speed of various materials. In most cases, such a tool is equipped with a saw up to 35 cm long, which allows cutting parts up to 10 cm thick.
In order for the cutting element to serve for a long time without breakage or cracks, it is necessary to provide it with optimal tension along its entire length. For this purpose, screw and leaf springs are used. As an additional option on factory devices, it is provided air pump to remove sawdust from the cutting line. A unit with a drilling unit is useful, but you need to pay extra for each additional unit.
Assembly instructions
A jigsaw is made from a refrigerator compressor or a regular drill. The cutting blade can be set in motion using a motor from washing machine. Another option is to use hand jigsaws and old sewing machines. The figure shows a design drawing.
How to remake a manual jigsaw
First of all, the table is made. For this, a sheet of thick plywood or metal is used. Through holes are cut out for the cutting blade and fasteners. Through them, the manual unit placed below is fixed to supporting structure. Further jigsaw table attaches to any stable wooden table. Guide rails are added.
If necessary, the machine can be quickly disassembled.
The standard device is equipped with springs that provide the file with the required level of tension. You can’t do without a rocker arm; one of its edges is under spring tension, the second provides attachment to the cutting element of a jigsaw. You can also clamp the blade between two guide rollers.
Before starting work on a homemade jigsaw, be sure to turn off the pendulum stroke.
Sewing machine machine
A jigsaw from a sewing machine contains a saw speed regulator, provided by a speed switch on the equipment.
For manufacturing, the thread weaving mechanism is removed. In most designs it is placed at the bottom. Unscrew the bolts, knock out the cotter pin, remove the drive shaft leading to the thread weaving unit.
Then the upper protective panel opens, the groove along which the needle moved expands to the width of the file. Jigsaw saws are slightly modified: they are cut according to the size of the longest needle that could be installed on the machine. In order not to make an adapter for fixing cutting element on seat, grind down the upper incisors, making the lower part of the blade sharp. A cutter is installed in the needle holder. After this, they begin cutting out the blanks.
Using a homemade jigsaw, anyone can make furniture, modern convenient shelves and other wood products. Its mechanism helps to cut wooden parts absolutely any shape. And it can also be used to process plastic and other dense materials. In order for a jigsaw machine to comply with all norms and rules, you need to carefully approach the choice of its design. Additionally, drawings from the Internet will help you make a jigsaw machine with your own hands.
Design of jigsaw machines
Absolutely any electric homemade jigsaw machine contains these parts:
- drive unit;
- connecting rod assembly;
- saw;
- work surface;
- saw tension mechanism;
- additional mechanisms.
The material to be processed should be placed on the work surface. Many models are equipped rotating mechanism, which changes the inclination of the cutting surface. In order to facilitate the application of markings to the material being processed, graduations are applied to the working surface. It is worth choosing a jigsaw with a large work table, because it will allow you to make the longest cuts. Basically, for most models of jigsaws, this figure is about 35 centimeters. Optimal power drive for a jigsaw machine assembled by yourself is no more than 200 watts.
Connecting rod mechanism capable of converting drive rotation into forward movement and transfers it to the saw. The optimal frequency of saw movement per minute is about 900, and the amplitude of vertical movement should not exceed 6 centimeters.
Many types of jigsaw machines are equipped with a speed controller, which allows adjustment depending on the type of material. The 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, the files can be changed, their width ranges from 2 to 12 millimeters. A manual tension mechanism secures the file for smooth cut. Its role is played by leaf springs or coil springs.
Main types of jigsaw machines
All jigsaw machines are usually divided according to the following characteristics:
The most popular are jigsaws machines with 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 sheet of material.
Double slide jigsaws have a main difference. It lies in the fact that there is another rail in the upper part of the frame. 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 no more than 9 centimeters. Additionally, the machine comes with a comfortable work table with height and angle adjustments.
Suspension jigsaws are not equipped with a stationary frame and have greater mobility. When performing work, the cutting module moves, not the material being processed. The working module itself is independently fixed to the ceiling, which is why the size of the workpiece does not matter. The cutting mechanism moves with your own hands, regardless of the bed. At the same time, it becomes possible to make a wide variety of patterns.
Jigsaws with stops and degree scale ideal for the most precision work using 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 with your own hands
When developing a drawing of a homemade jigsaw machine total number elements must be reduced to a minimum number. A saw with a fixed rocker, an electric motor and a bed will be enough. If desired, a motor from any electric machine will do. People who own a jigsaw are much luckier manual type. It is necessary to make a special stand from a plywood sheet and attach a jigsaw to it. To secure it, it is worth making holes in the base of the jigsaw. Thus, the simplest jigsaw machine can be considered ready-made.
Next, it’s worth talking about more functional and complex models of devices that you can make with your own hands. Homemade bed done from a sheet of plywood 12 millimeters thick, textolite or plastic. Such a bed consists of 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 position the eccentric with the rocker, which must be connected by a metal plate with bearings and bushings. This entire structure must be secured with screws. To install the intermediate shaft, you need to find several bearings. A special metal pulley is placed quite tightly on the shaft, and the screw connector is securely fastened. In a similar way, you need to make a homemade eccentric for the device.
In order to change the frequency of movement 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, you can adjust the amplitude of movement of the rocker, which consists of several wooden rocker arms attached to the stand with hinges. The ends of the rocker arms have through cuts into which screws are inserted for tension. A file is attached to the other ends, moving using metal hinges. To secure the file, place it in a special groove on the working surface.
Blade mounting device can be considered the most important. During assembly jigsaw machine DIY this part is worth paying a lot of attention to. The plates inserted into the rocker arms carry a huge load during operation, which is why they need to be properly strengthened and tightened with fastening materials. The two mounting earrings do not need to be tightly compressed with screws, which will allow the axle hinges to move.
Rocking stand mechanism It is best to make it from solid material. On one side you need to make a groove for the rocker arm, and on the other you need to cut a rectangular opening for the second rocker arm. To make it easier to make holes, it is worth folding the stand from several parts.
Cutting small pieces of wood is done with a jigsaw. The device is small in size and usually has an electric drive. Factory models differ in their characteristics and cost. For small volumes of wood processing, it makes sense to make a jigsaw machine yourself, using improvised materials. This requires a few factory parts.
A factory-made jigsaw is reliable device, the operation of which is guaranteed by the manufacturer. Manual models are low cost. Stationary devices are expensive, but provide proper comfort when processing wood. The set of components in the device is largely the same for everyone.
The design consists of the following parts:
The part to be processed is placed on the work table. The size of the workpiece depends on its dimensions. Some models have Rotary table, which makes working with the part easier - visibility improves. The presence of graduations makes it easier to mark the material.
Average characteristics of factory machines:
Models for specialized purposes may have radically different characteristics. There are small size specifications for processing small parts. As well as models of large sizes, the industry also produces them for retail sale. But such options will be very expensive.
In the middle class there is high competition for consumers, so the devices will be cheaper. The characteristics are also tailored to typical tasks carpenter Based on them, you need to make drawings of a jigsaw machine with your own hands. Complex components for it are purchased in the store.
Experts classify jigsaws by type of design. The design features of the mechanism determine the processing capabilities of wooden products.
The classification is carried out depending on the design of the jigsaws.
Device types:
- With lower support.
- Double-support.
- On a pendant.
- With degree scale and stop.
- Universal.
Models with a lower support have become most widespread. The frame of the desktop factory device has 2 halves - lower and upper. The sawing and chip cleaning model is located on the top of the bed.
The lower frame contains a controller, an electric motor, a final drive, and an on/off button. This machine allows you to work with any materials and any size.
The presence of two supports in a jigsaw is advantageous in that the upper half of the bed has an additional rail. This jigsaw is ideal for cutting small parts. The thickness of the workpieces on both models should not exceed 8 cm. The worktable of such machines, as a rule, can be adjusted in height and angle of inclination.
Suspended devices do not have a fixed frame, but are distinguished by their mobility. The material being processed is set motionless, and the master moves the working module. since the latter is attached to the ceiling, the thickness of the material is not limited. The tool is moved manually, regardless of the bed. This allows you to make patterns of complex shapes.
The presence of a scale of degrees and stops is suitable for those craftsmen who carry out processing according to the drawings. Marking allows you to avoid errors when working. There are universal models of machines on the market that allow you to perform several operations. This machine allows you to perform drilling, cutting, polishing and grinding. The cost of such devices will be much higher, but working with them will be more comfortable. These are industrial specimens.
Designs and drawings of options presented on the network homemade jigsaw are different. This is due to the imagination of the authors and the desire to make a device that will stand out from the rest. Only the concept is the same in most cases - they take a manual jigsaw as a basis and repurpose it.
Home woodworking enthusiasts often look for information on how to make a jigsaw with their own hands without any special skills. You can use a ready-made manual jigsaw as a base. The mechanism does not require careful modification. Factory handheld device- this is the drive. But the crank mechanism will have to be developed independently. Manufacturers are trying to offer consumers platforms for quick remodeling, but personal needs can only be satisfied with their product.
Assembly order:
- A support table is made. A sheet of metal is taken as a material and a hole is made in it. The shape is oblong, 3-4 times wider than the saw blade. Holes for fasteners are made nearby.
- The factory device is fixed at the bottom of the support table. Holes for fasteners are made next to the hole for the saw blade. Screws with countersunk head. This is necessary in order to ensure a perfectly flat plane of the table. Otherwise, the processed products will cling to the caps of the wines, which will cause inconvenience in work.
- The structure is fixed on a wooden table.
The advantage of creating a jigsaw machine with your own hands is that the factory tool can be disconnected at any time. When necessary, you have an ordinary manual jigsaw in your hands. Therefore it is better to purchase manual option tool that can be used on homemade machine- it’s cheaper that way. Stationary devices are expensive.
Comfortable work with wooden products can be achieved by installing guide rails on a homemade support table. Additionally, markings are applied to the table, which makes it easier to measure distances on parts during processing.
A manual jigsaw as the main device for a machine has disadvantages. the main problem lies in the file - it is too wide manual models. Because of this delicate work It is difficult to do on wood with it - the curvature of the lines is limited.
The previous design is simple and has no additional details, which make working with wood easier. The direction of modernization is the possibility of replacing the file with a thin one.
Options for improving the design:
- Build a rocker. The structure will be tensioned by springs on one side. The second side of the rocker is fixed to the file.
- Secure the file between two rollers. They serve as guides for the thin file.
- A stationary factory device is used as a drive for a system of two rocker arms. A file is pulled between the latter. The movement is transmitted from the factory device to the lower beam of the saw.
Design upon purchase or self-production you have to choose based on personal preferences and desire to tinker with technology. Using guide rollers is a less popular option - its reliability is poor.
Modernization by installing rocker arms is common. It is better that the factory device only serves as a drive for the jigsaw file. To do this, you need to turn off the pendulum stroke in the tool.
The heir to a grandparent's estate often gets an old sewing machine. It has already served its purpose for sewing clothes, since more precise equipment is now being produced. If you don’t have a jigsaw on your household, you don’t have to spend money on buying one. It is made with your own hands from a sewing machine.
Procedure:
Now the jigsaw for figured sawing ready for plywood. WITH manual drive It will be more difficult to work because your legs will get tired. Additional disadvantage Vibrations from force on the tool will serve. The electric drive of the machine, converted into a jigsaw, partially solves the problem of vibrations.
An expensive jigsaw can be replaced with a design self-made. It will not be inferior in quality and functionality if you approach the assembly process responsibly. It is important to make high-quality plywood mechanisms that serve as a support table. It is desirable that the table be able to rotate. For option with sewing machine it will be impossible to do this. If desired, markings are applied to the table to make it easier to measure parts during work.
