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 jigsaw machine independently, using improvised means. This requires a few factory parts.
A factory-made jigsaw is a 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 specifications Not large sizes, 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 the typical tasks of a 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.
The designs and drawings of the homemade jigsaw options presented online 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. Countersunk head screws are used as fasteners. 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 a manual version of the tool that can be used on a homemade machine - it’s cheaper. 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.
Jigsaw manual type as the main device for the machine has disadvantages. The main problem is 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 does not have additional parts that 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 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 the version with a sewing machine, this will not be possible. If desired, markings are applied to the table to make it easier to measure parts during work.

Tabletop jigsaw machine - equipment for cutting, sawing out figured 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 at different angles. This is necessary for making bevel cuts. Often for convenience swivel mechanism, stops, guides, markings are applied. 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.
A standard jigsaw tool is characterized by a vibration 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 additional option provided on factory devices 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
The jigsaw is made from a refrigerator compressor, conventional 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. They cut out in it through holes for cutting blades, fasteners. Through them, the manual unit placed below is fixed to supporting structure. Next, the jigsaw table is fixed 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 the 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.
Many people have known the fun of cutting with a jigsaw since childhood. The technology is simple. But despite the apparent ease and simplicity of the work, you can get very beautiful lace from wood or plastic. This is a very slow process that requires persistence and patience. To make work easier, jigsaw machines were developed. They are functionally divided into two groups: with manual and electric drive.
Jigsaw device with muscle drive
A homemade machine is easy to make. You can find many drawings of this plywood product. Using a jigsaw, your own hands and improvised tools, a simple but functional device is assembled in a short time.
The scope of application of jigsaws is extensive. They are used for sawing figured products from a variety of different materials. Machines are also necessary for cutting lumber. In this case, the outer contour of the workpiece remains intact. If you use different nail files, then homemade jigsaw will process perfectly natural wood, plywood, chipboard, plastic, metal, in particular aluminum.
Examples of do-it-yourself drawings of a jigsaw machine, which operates using muscle power, were repeatedly cited in various Soviet-era magazines.
Files for such a jigsaw machine are produced in the form of a flat blade.
Main parts of the machine:
- Bed (A).
- A work table with a slot for a saw (B).
- A large drive pulley that acts as a flywheel (D).
- Small drive pulley. The drive is combined with a crank mechanism (D).
- Levers (B).
- A pedal that spins the flywheel through the crank assembly (E).
- Saw tension unit (G).
The master, constantly pressing the pedal with his foot, spins the flywheel. Through the belt, the movement of the flywheel is transmitted to the second pulley. Which, in turn, causes the crank mechanism with the saw blade to move.
If the flywheel is correctly balanced, without distortions and with a uniform, correctly selected mass, then the file achieves good smooth running. A similar machine for cutting plywood allows you to quickly produce many simple, similar products. The time and effort required for sawing is significantly reduced.
With this machine design, the size of the initial workpiece is limited. It depends on the length of the levers (B). When complicating the pattern, it is necessary to rotate the product around the saw.
Since the foot drive does not ensure a completely uniform stroke and limits the freedom and imagination of the master, most often such machines are replaced with electric ones.
Construction of a jigsaw machine
Electric band jigsaw - this is a household universal device for the manufacture of souvenir products, furniture, various interior items. There are many options for manufacturing such machines. But the main elements on which the quality of the product and ease of use depend are the electric motor and the blade.
Main design elements:
- Saw blade.
- Crank mechanism.
- Drive part.
- Belt tension unit.
- Stand or work table.
- Various auxiliary elements.
Design and principle of operation
Conversion from a hand jigsaw
The first step is to make a working table for the mechanism. Suitable for these purposes a metal sheet or thick plywood. Holes for the cutting tape and fasteners are drilled and sawed out in the worksheet.
The jigsaw table is then placed on regular table. Once secured, the guide rails can be assembled. To reduce vibration, just cut out the rubber gasket the right size and put between jigsaw table and the main surface.
The above design is convenient in that it can be easily disassembled and can be used again as a hand jigsaw.
Since the standard device has springs that tension the saw, a rocker arm is necessary. One edge of the rocker arm is attached to the cutting element of the machine, and the second is under tension from springs. These simple steps will easily turn regular jigsaw into the machine.
When operating the device, it is important not to forget to turn off the pendulum stroke before starting cutting.
Assembly from a sewing machine
You can also quickly and easily assemble a homemade jigsaw from a sewing machine. Moreover, this device has interesting feature- regulator of the stroke of the nail file, since sewing machines have a speed switch.
First, at the bottom of the machine you need to find a thread weaving knot. To do this, several screws are unscrewed. The cotter pin located inside is knocked out and the drive shaft, which is connected to the thread weaving complex, is removed. After completing this procedure, the top panel is unscrewed. The groove along which the needle rode widens slightly to accommodate the saw blade. The files themselves are shortened slightly to the length of the needle. To fix the saw itself, you can make an adapter. But the easiest way is to grind off the top part of the cutting blade and sharpen the bottom. After which you can insert the nail file into place of the needle and get to work.
When working with jigsaws of any type, you should not forget about safety rules. Do not leave the device turned on for a long time without supervision.
If the master long hair, then it’s better to pick them up or use a special cap. It is better to roll up the sleeves of your clothes. The room should be well ventilated. In the room where carpentry work is carried out, a first aid kit with emergency aid for cuts must be kept.
A tabletop jigsaw machine will be useful to every craftsman who cuts out thin parts. However, it is not always possible and meaningful to purchase a full-fledged machine. In that case, get down to business and make it yourself!
The structure of a jigsaw machine - what lies inside?
Jigsaw machines are more related to special tools than to devices that are needed as to an experienced master, and for the amateur who manages the garage. Their purpose comes down to a special task, namely cutting out complex curved contours from sheet materials. A special feature of such machines is the execution of cuts without violating the integrity of the external contour. Most often, sawing occurs on wooden and derivative materials (plywood, chipboard, fiberboard), although modern machines equipped with appropriate saws can also work with other materials, for example, plastic or plasterboard.
Such equipment has found application in the music industry (manufacturing musical instruments) and, of course, in the furniture room. Those who like to make things in their own workshop also buy such units. The structure of a traditional jigsaw machine, designed according to all the rules, looks like this: working surface, on which the saw is mounted, hides the drive (electric motor) and the crank structure underneath. The tension mechanism can be located either below or above the machine.
To process a part, it must be placed on the workbench. Many models have the ability to rotate it at different angles to make bevel cuts. The stops and guides on the surface, as well as the rotating mechanism, can be marked, which greatly simplifies and speeds up the work. The length of the cut depends on the length of the work table - most models are limited to 30-40 cm. Electric motor power is an important, but still far from the most fundamental factor, since the machine has a huge reserve of unclaimed power. For example, for a home workshop or even small production, an “engine” of only 150 W is sufficient.
The crank mechanism is much more important detail, because in this case the quality of transmission of the drive torque into the translational-reciprocal motion, directed in vertical plane using a file.
Standard jigsaw machines are considered to be devices with an amplitude of movement of around 3-5 cm and a vibration frequency of up to 1000 per minute. Many models provide a change in speed mode for different materials. The jigsaw file itself is usually made up to 35 cm long and is capable of sawing material up to 10 cm thick. The width of the files can vary in a fairly wide range - from very thin two-millimeter to coarser ten-millimeter, with a thickness from 0.6 mm to 1.25 mm.
Even the thickest and widest file will easily break if you do not provide sufficient tension along the entire length of the file. Leaf and coil springs are used for this. Quite often, such machines are equipped with an air pump, which cleans the cut from sawdust by blowing it, as well as a drilling unit. The latter device is especially useful, because in this case the master does not need to be distracted by the connection electric drill and drilling a hole - everything happens on the working plane of the machine. Of course, you have to pay for convenience!
How to make a jigsaw with your own hands from a manual jigsaw?
On the Internet you will find many different designs homemade machines, but most of them come down to repurposing into this device. By using your ingenuity and watching the video, you can easily make a homemade jigsaw from this tool. The jigsaw only needs a little modification. In fact, it plays the role of a machine drive and a crank mechanism, but the rest needs to be thought out and implemented.
Of course, manufacturers are trying to please consumers in this area as well, offering their own platform options for quick and convenient remodeling, however, in reality only you can make a device that suits your needs. So, the first step is to make a support table, for which they most often use sheet metal. You need to make a beveled oblong hole in it for the saw blade and holes for fasteners (countersunk screws are recommended), and attach the jigsaw to the bottom of the support table.
This structure can only be strengthened on a wooden table. You can go beyond this and install guide rails. The convenience of such a device lies in the fact that in addition to performing functions that are not entirely inherent to it, you can always disconnect the drive and with a slight movement of your hand turn it back into a manual jigsaw! If you constantly need this tool for work, it makes sense specifically for the machine - it will be cheaper than spending money on a real machine.
Advantages and disadvantages - we continue to modify!
But such a unit inherits not only the advantages of the tool, but also its disadvantages, in particular, the file is too wide for filigree work, which significantly limits the curvature of the lines. If there is a need for this, there will be a way out. So far, our machine differs from the classic jigsaw unit in the absence of springs that would ensure sufficient tension on the file. But it’s quite easy to build a simple rocker, which on one side will be under the tension of springs, and on the other, fixed to a nail file.
There is another option - to clamp the nail file between two guide rollers, but the first option is still more reliable. Be sure to turn off the pendulum action on your jigsaw before using it. homemade machine. There is another design - if your tool is powerful enough, then it can only serve as a drive in a structure of two rocker arms, between which a nail file is stretched. The movement is transmitted through a file attached to the lower rocker.
Machine from a sewing machine - giving a second life to old tools!
If you inherited a foot-operated or manual sewing machine from your grandmother or mother, consider yourself the owner of an excellent jigsaw machine! Of course, for this you need to “work a little magic” on the machine. First, remove the thread weaving device, which is usually located at the bottom of the machine. There is nothing complicated about it, just unscrew two bolts. Then we knock out the cotter pin and remove the drive shaft leading to the thread weaving mechanism.
Having unscrewed the top panel that protects the mechanisms, it is necessary to expand the slot in which the needle went. Be guided by the needs and width of the nail file that you will use in your work. Files for a jigsaw machine of this kind also need to be slightly modified, namely, cut to the maximum length of the needle that could be used on this machine. Having ground off the upper teeth and sharpened the lower part to the point, all you have to do is insert the file into the needle holder and test your machine in action!
An electric jigsaw is a type of equipment for wood processing. Nowadays, the choice is presented not only in the usual manual version, but also in electric. These models, for example, Vario 502 dks, Dremel have high performance, are quite easy to use, and come with a large number of removable components.
These devices can be used in household, and in production. Today, such a mechanism can be bought ready-made or made with your own hands, for example, from an old sewing machine.
1 Technology of use
The main working element of a manual jigsaw is small files, which usually have a length of 50 to 120 mm. It is driven by an existing electric motor and makes translational movements vertically during processing of the product. In some mechanisms it works according to the pendulum type.
The workpiece itself in this design is attached directly to the base of the equipment. Such a fixation allows the worker to more easily operate the system and freely adjust the angle of the tool. Operator safety in this design is ensured by the presence of a special screen.
These models appeared on mass sale in last years. Previously they tried to make them for home use from a sewing machine. Today there is no need for this. The choice of models is very large.
1.1 Advantages and disadvantages of using jigsaws
TO strengths It is this technique that must be considered:
- Possibility of using the device for a wide range of woodworking thanks to a large number replaceable cloths.
- Greater reliability in use: due to the wide blade of such a mechanism, you can avoid breaking parts made of wood or tile during processing, as well as perform any complex contours with a minimum of effort.
- The ability to feed a piece of wood with both hands by attaching it to the blade. Previously, without such a device, working with manual samples was much more difficult.
- Ease of processing any kind of material – even relatively small ones the jigsaw can easily cope with wood 50 mm thick, not to mention more powerful models.
- Wide range of processing options.
Among the disadvantages of using such a device, the short stroke of the samples is usually noted, due to which the work with thick webs is significantly more complicated.
It is also impossible to make the bending radius as small as when using a manual sample (due to the peculiarities of fastening the file).
2 Scope of application of machines
Modern electric jigsaw machines are suitable for next works to choose from:
- Sawing complex contours from a sheet blank.
- Treatments inner surface workpiece without violating its contour integrity.
- Finishing of some samples.
A tabletop jigsaw machine is used primarily for processing wooden workpieces. It is most often used in the production of furniture and musical instruments. In recent years, they have also often begun to be used for the production of decorative items, as well as souvenirs.
2.1 Consumables
The main consumables that it has table jigsaw, are files, including spiral ones. They differ in length, size of teeth, distance between them and are selected for each material individually.
Usually, when setting up a jigsaw machine with your own hands and buying files for it, experts recommend choosing Supplies for the following features:
- To cut wood or plywood workpieces, choose saw blades with a pitch of 2-4 mm.
- Metal samples, as well as plastic, are usually processed by choosing 1-2 mm files, including spiral ones. Experts who provide reviews on the use of such components recommend choosing models with a wavy edge. The choice of these is very large.
- When working with tiles, use special saw blades with an abrasive coating.
You can select these elements for processing wood and other materials not only based on reviews, but also based on technical characteristics the equipment you have chosen.
After all, almost every machine has a list of consumables, including all the files suitable for it for certain products.
Also, do not forget about additional elements such a design, which, for example, in the Dewalt, Dremel, Holzstar, Vario 502 dks models includes a drilling unit and an air pump. Their choice is great.
2.2 Design features of jigsaws
Currently, an electric jigsaw machine, in addition to those products that are created at home with your own hands, is presented on the market in huge quantities various products. Their choice is really wide, including models Dewalt, Holzstar, Vario 502 dks.
They are classified according to the following features:
In order to choose the right jigsaw, you need to It is already possible to analyze the device according to all parameters. And then you can get the ideal component to perform any task. You can also assemble a tabletop jigsaw with your own hands using general recommendations for the production of such devices.
It will not be difficult to do this yourself using a sewing machine or other similar mechanism. The main thing is to study the design well, select the necessary components and do everything to make the model reliable.
