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:
- Working 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.
Desktop 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. Stops and guides on the surface, as well as swivel mechanism may have markings, 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 in this case it is on this that 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 of 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. Last device 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 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 of this kind also need to be slightly modified, namely cut to maximum length needles 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!
A very fast and fairly compact tool, it can be incredibly useful for making straight and curved cuts. Appearance and the functionality of the jigsaws sold are impressive, making one believe in the incredible complexity of the design of these devices. In fact, to recreate such a mechanism, it is enough to understand the principle of its operation, have instructions and the desire to do something with your own hands. It is not at all necessary to be an expert in technology with many years of experience (although this quality will not be superfluous). Next, we will conduct a detailed analysis of the average jigsaw model with drawings, and provide two detailed guides for making such a tool yourself.
How does an electric jigsaw work?
Although the device of a jigsaw is not particularly complicated, its mechanism has certain features that require familiarization. To understand how to make a jigsaw, you first need to understand what causes the saw blade to make reciprocating movements. For the clearest understanding of the principle of operation of the device, we will present the main components that make up the mechanism of the instrument and describe their interaction with each other.The basis of any electric jigsaw is the following components: an electric motor, a gearbox and a rod with a saw blade clamp. To the secondary ones, but no less important elements, include the start button, support roller, cooling fan and soleplate. As additional functionality, many models have a pendulum stroke, a dust collector, lighting and a laser guide. We will not touch upon the operating principle of the latter, and will move on to a description of the interaction of the main elements of the mechanism.
The high-frequency movements of the jigsaw saw blade originate from an electric motor, started by pressing a button or directly from the network. Rotation is transmitted along the shaft to a special “gearbox” mechanism with an eccentric, which interacts with the rod, forming a reciprocating movement. The mount installed at the end of the rod holds the saw that makes the cut. To minimize the load on the rod with the gearbox, the rear edge of the saw blade rests against the support roller. In this way, all components of the device are involved to perform the main task of sawing all kinds of materials.
Electrobolic drawings
A detailed study of any device is much easier when there is detailed diagram with a description of each element. Thanks to the exact names of parts with dimensions, the general understanding of the principle of operation of the mechanism becomes more clear. Below we have placed several detailed illustrations, since assembling an electric jigsaw with your own hands with detailed drawings is much easier than relying only on your understanding of the design features.
We hope that the presented diagrams will completely clarify your understanding of the structure of such a mechanism and provide useful food for thought in assembling your own jigsaw.
Making a jigsaw with your own hands
For a craftsman who understands the principle of operation of any mechanism, it will not be difficult to reproduce it, especially if he has detailed instructions. The bicycle has already been invented, and to make it yourself, it is enough to have a kit available necessary details and tools. The guide below will demonstrate in detail how to make a jigsaw with a complete listing of the elements and tools required for the job. The product being created is not a stationary device, but a mobile saw with an electric drive. The device has not much power, but it is enough to cut wood up to 5 mm thick.
Required materials:
- Wooden block - 150x75x25 and 75x25x25 (width, height, thickness in mm)
- Metal plates – long and rectangular (as in the photo)
- Jigsaw blade with U-shank
- Electric motor RS-540 12V (any similar one can be used)
- Circuit closing button
- Nozzle gas stove
- Bicycle spoke
- Plastic circle with a diameter of 260 mm
- Plywood - 120x50x5
- Set of self-tapping screws, bolts and nuts
- Hacksaw for metal
- Triangular file
- Pliers (2 pcs)
- Screwdriver or drill with a set of drills
- Metal scissors
- Pencil
Assembling the jigsaw will begin by cutting out the handle from a larger block. To do this, just cut it, giving the rectangular board an L-shape, as in the photo. The dimensions of the cut part are set “by eye”, based on the preferences and size of the operator’s hand.
One of the most important nodes The device, which serves as a movable rod and clamp for the saw blade, requires increased reliability. This item made from a long metal strip, 1 mm thick. At the end, trace the outline of the file shank, after which a notch is made with a triangular file to create a pressure plate. Part of the metal strip is bent with pliers along the contour of the shank, after which a file is installed in the improvised mount and drilled through hole For additional fixation using a bolt.
The saw blade mounted on the rod must be connected to the device using a guide. This part is made of metal plates rectangular shape. Using pliers, bend the center of the plate into a flat groove for the rod with side mounting lugs. To prevent abrasion of the wood and facilitate the movement of the saw, we apply a similar piece of metal to the front side of the prepared handle and screw it together with the groove. As a result, the following design should be obtained.
At the end of the rod, we carefully bend the metal until we get a kind of loop into which the end of the crank mechanism lever will be inserted.
We screw the previously sawn-off wooden rectangle to the top. It will serve as a stand for the motor, creating extra space for installing crank elements.
The conversion of engine rotations into reciprocating movements will occur using a simple mechanism made of a round plate, a gas nozzle and a weight-bearing spoke. In the center of the circle, drill a hole with a diameter equal to the threaded part of the nozzle (so that it fits as tightly as possible). Next, install the nozzle in place and fix it using epoxy resin. We put the dried structure on the electric motor shaft. If the nozzle hole is too narrow, you can widen it with a drill of the required diameter. Between the center and edge of the circle, drill another small hole with the diameter of a bicycle spoke.
Unfortunately, it is not possible to find the upgraded gas stove nozzle with a side screw used in the instructions everywhere. If only an ordinary one is available, it can be fixed on the shaft using tin and a soldering iron, as in the photo below.
Having combined the motor with the round plate, it's time to turn it into a real crank. To do this, take a bicycle spoke and use pliers to bite off the curved head and threaded part to form an even metal rod. Next, we retreat 10 mm from one end and bend it at an angle of 90°. We insert the bent part into the previously prepared eye in the rod and lift it up so that the saw fastening screw rests against metal plate.
The accuracy of the next step is most important, since the amplitude of movement of the saw depends on it. It is necessary to determine the exact location for the second bend of the rod so that the crank and rod connected by it work most efficiently. To do this, we place the engine in the place of the future mounting and place the outermost hole of the circle upward. Next, we bring a rod to the hole, the opposite edge of which is inserted into the eye of the rod raised all the way and mark the place of the bend. We bend it at an angle of 90°, insert it into the hole of the circle and check the functionality of the mechanism. If the crank works as it should, fix the motor in place with a metal plate.
The next structural element will be the installation of a sole, which will also serve as a support for the saw blade. A similar part can be made from regular plywood, 5 mm thick. In the center of one of the ends, we make a small cut (20-30 mm) and pass the file of our jigsaw into it. We fix it with a self-tapping screw with a countersunk head.
The final stage will be installing the start button and connecting the wires. The button can be displayed in any place convenient for you. The author considered it necessary to place it on hot glue in the corner of the handle. We create a basic electrical circuit (motor-button-network and motor-network) and connect it to a 12-volt power supply.
For a smoother ride, it is recommended to lubricate the rod with oil.
A more visual demonstration of this instruction, but unfortunately without comments, can be seen in the video below.
Homemade jigsaw for polystyrene
Assembling a fairly convenient and reliable device for cutting thin wooden blanks and polystyrene. This method almost similar to the previous one, but has a more functional design.

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 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 no specifications large sizes, for processing small parts. As well as models of large sizes, the industry also produces them for retail sales. 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. Countersunk head screws are used as fasteners. This is necessary in order to ensure perfect flat plane 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 needed - in the hands of an ordinary one manual jigsaw. Therefore it is better to purchase manual option a 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 in manual models. Because of this, fine woodwork is difficult to perform 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 curly cutting on plywood is ready. WITH manual drive It will be more difficult to work because your legs will get tired. An additional disadvantage will be vibrations from force on the tool. 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.
This article will discuss the design of a homemade machine made from a household jigsaw. Below will be given step-by-step instruction, photos, videos, as well as drawings and diagrams.
Introduction
There are a lot of design options - from the simplest, where it just sticks out from the tabletop, to quite complex structures with guides, the ability to cut at an angle, when it is possible to set not only 90 degrees to the base, but also change the angle (well, within reason, of course). There are devices (machines) for, that is, making straight and even cuts.
Such devices are increasingly used due to their versatility and functionality. In fact, their parameters and purpose are similar to stationary machines and have a strictly defined practical use in every workshop.

Preparatory stage
- draw up sketches and make a drawing of the future product,
- make paper patterns for future elements and details
- stick templates onto blanks for future parts.
There are two ways to make templates - take tracing paper and draw the kennels of the future workpiece on it. This has been done since ancient times, since nothing is needed for this except a ruler and a pencil. However, if you have a computer and a printer, of course A3 would be nice, but A4 is also suitable (you just have to print several sheets and then glue them together), then the process of drawing with a pencil and ruler can be replaced by drawing the contours of the blanks on the computer.
Then we cut it out with a stationery blade or just a sharp knife.
After that Once the template is ready, it needs to be glued to the workpiece.
Tip: There is no need to glue it tightly, since in the future you will have to remove the template, and this will be difficult if you glue it tightly. Accordingly, you can glue it, for example, with stationery glue, use a glue stick or, as in our example, spray glue.
Creating blanks
At this stage you need to do:
- Cut the blanks exactly according to the template,
- Process the workpieces - align the ends, remove burrs
- Drill the necessary holes;
- Make grooves with a file;
- Drill out the seats for the bearings;
- Select grooves with a router for the cover and a seat;
We install the bracket. It should be noted that the bracket must be fastened without over-tightening the nut - there must be free movement. To do this, use a self-locking nut and only tighten it slightly.
Installing the spring should not be difficult. You need to do it as shown in the photo below.
For future fastening of the file, you need to make a simple clamp in the form of a plate with two holes. It must also be installed on the bracket using a self-locking nut. Moreover, the backlash of the plate in the seat is very important because the bracket moves, and a clamped plate will restrict its movement.
Below is a sketch of the design of the upper attachment point for the file.
Then it is necessary to make technological holes for the jigsaw controls so that it is convenient to change the engine speed, you can gain access to the start button and its lock. There is another solution that makes it more convenient to turn on the tool - this is to place in an easily accessible place on the machine body an socket and a switch that would turn the voltage on and off in the socket. We plug the jigsaw cord into a socket, and it turns out that we will turn it on and off using a switch installed in a place convenient for us. However, this is a matter of taste.
So, below is the manufacture of technological holes on the body.
This is what the controls look like when they are now available.
Now you need to make clamps for the file itself. The principle is simple - take a bolt and make a cut at the base of the head, but not all the way. In the future, the file itself will be inserted into this cut. The principle is shown in the photo below.
This is how the upper saw attachment unit is installed and assembled.
The lower assembly is almost similar to the upper one, except that it is not a plate that is used, but a standard file (you can use a “BU” one), almost the entire cutting part is sawed off with an angle grinder and the shank is left. A hole is made in the remaining cutting part with a similar bolt with a slot at the base of the head, into which the file will also fit. The principle is shown below.
After the file is secured, we install the jigsaw itself. We fasten it with bolts with countersunk heads so that they do not stick out on the tabletop of the machine.
Now we need to adjust the perpendicularity of the file relative to the table of our machine. To do this, you can use a square, or, as in our case, just a block that is precisely trimmed. We make the adjustment as follows. To adjust the file left/right, the top plate is adjusted - its displacement on the axis - respectively, in the desired direction.
And to adjust the saw blade position forward/backwards, the saw blade mounting unit itself is shifted forward or backward.
The machine is almost ready, all that remains is to make and install the plate that surrounds the jigsaw file. It can be made from PCB or any piece of sheet plastic.
This completes the manufacturing of the jigsaw machine.
We hope that the material presented was useful to you.
