A jigsaw allows you to quickly and efficiently cut wood. consists of a working surface, stands, motor and spindle assembly. Some devices are made on stands. Clamps are quite often installed on the side of the work surface. It is also worth noting that the models differ in power. The manufacture of a jigsaw machine can only be carried out if the instructions are followed.
Desktop devices: expert reviews
If you believe the reviews, then making a desktop modification is very simple. First of all, a stand is prepared for the working surface. Its width should not exceed 30 cm. It is more advisable to select a single-phase motor with ultimate voltage 220 V. A homemade jigsaw machine (desktop) produces an average operating frequency of 55 Hz.
Reviews from experts say that it is better to use yews made of steel; if desired, you can cut them yourself. The file is installed on a spindle assembly, which is attached to the stand. Many models use a latch that acts as a stop. To secure the file, a small screw is used.
Models with legs
If necessary, you can do this yourself. Modification drawings include frames different sizes, and spindle units are usually used with guides. Many models are made on a wide bed. Legs can be installed from tubes. There are also machines with plates. After cutting out the working platform, you should work on the spindle assembly.
If we consider devices with control units, then the model will require a controller. It is more expedient to use a 220 V commutator type motor. Yews on jigsaw machines are installed as a rotary type. The direction must be welded to the edge of the plate. In this case, the file must be securely fixed. Optimal height spindle assembly is 2.2 cm. At the end of the work, it is important to install the power cable and connect the equipment.
Reviews of devices with wide frames
Professionals are able to assemble a jigsaw machine with their own hands. Device drawings indicate the presence of wide stops. However, first of all you need to install the bed. If we consider a simple machine, then the lock for modification can be selected of a small length. Reviews from experts indicate that two racks are enough for the model. To assemble the machine it is used welding inverter. The spindle assembly itself is installed in the central part of the working platform. The hole for the file can be made with a milling cutter. It is also worth noting that experts do not recommend using two-phase motors.
Compact modifications
By following the instructions, you can assemble a compact jigsaw machine with your own hands. Device drawings include double racks and narrow frames. Beds are used with a low profile. Many models have a spindle assembly without a holder. In this case, the guides are installed to a short length. For self-assembly For models, it is recommended that you first select a high-quality frame.
Additionally, a clamp is soldered under the working plate. To reduce vibration levels, you can use a pad. Regular glue is used to fix it. The file for modification should be selected with a small thickness. Optimal distance installation of the central unit is 14 cm. At the same time, the width of the platform is on average 17 cm.
Jigsaws 2 kW
If you wish, you can make this jigsaw machine with your own hands. Drawings for assembling the modification are very easy to find. As a rule, frames are used with a width of 35 cm. The thickness of the plate should be about 1.5 mm. The hole for the file must be made before installing the central unit. If we consider models without stops, then the frame is used with a low profile. It is also worth noting that it is more advisable to install the spindle assembly on a lining.
A casing is used to reduce noise levels. Many models use multiple stops. In this case, the unit is installed at a height of 10 cm. It is better to fix the file on the plate. The clamp can be used as a screw type. After fixing the central unit, the motor is installed. For modification of this type, a device with a single-phase unit is suitable.
3 kW models
At 3 kW table jigsaw It's quite easy to do it yourself. Experts recommend using racks with wide stops. The clamps need to be installed only after the central unit. The modification file can be adjusted to 1.2 mm. Some experts make the hole after installing the frame. In this case, the supports are soldered to the sides of the table.
Next, it is important to evaluate the spindle size. It is more advisable to use the motor with a protection system and casing. It is also worth noting that collector devices that operate at a frequency of 45 Hz are very popular. They have low energy consumption and do not overheat. Holders are used to secure workpieces. The optimal spindle height is 15 cm. It is also worth noting that there are models with tuning plates. A flywheel is used to control the stand. A conventional controller is available to install the control unit.
How to make a 5 kW device
Having prepared several stops, you can make a jigsaw machine with your own hands. Reviews from experts indicate that 5 kW models are well suited for longitudinal cutting. Before starting work, all necessary tool. You will need a saw and welding machine and cutter. It is more expedient to assemble the frame for a jigsaw from steel plates with a thickness of 1.3 mm or more. You need to immediately provide a place for the motor. The frames in the devices are installed with a high profile.
At this stage, you can immediately cut a hole for the file. The plug assembly must be mounted on the top of the plate. Additionally, it is worth noting that the file will require a large holder. If we consider simple model, then the racks can be installed on the sides of the frame. Yews are of the rotary type. There must be a stand at the top of the frame. A small casing is fitted under the motor. On average, the width of the frame should be 35 cm. If we consider professional models, they use adjustable clamps.
Modifications for two quills
How to make a jigsaw machine with your own hands? The model with two quills is assembled only on a wide frame. First of all, the plates for the bed are cut out. If we consider a desktop modification, then it is more appropriate to install the control unit at the top of the device. The optimal frame width is 45 cm. In this case, the spindle assembly is installed behind the stops.
There must be provision for racks. Many models use transmission units. In this case, motors are only suitable for commutator type with a frequency of 30 Hz or more. The file is installed as standard in the holder. The optimal height of the spindle assembly for models is 35 cm. Quills for adjusting the bed are used with flywheels.
Models with three quills
It’s easy to make this one with your own hands based on a single-phase motor. Tools should be prepared in advance. Many models are equipped with frames with four stops. They have a long length and a high profile. It is also worth noting that spindle units are selected from. At the beginning of work, it is very important to calculate the length of the frame. If we consider ordinary spindle units, then the stand for them is prepared in a short length.
The central support must withstand heavy loads. A welding inverter is used to install the plates. The motor will require a casing that will significantly reduce the noise level of the device. The saw for modifications of this type is suitable for 1.2 mm. With a power of 3 kW, a device with three quills will produce a frequency of 55 Hz. To fix the flywheels, brackets are needed.
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 are equipped 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 hand jigsaw are small files that 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 using 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.
- Processing the inner surface of the 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 furniture production, 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 a tabletop jigsaw has 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 a huge number 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.
2.3 Electric jigsaw machine Enkor Corvette-87 (video)
The idea of creating a homemade jigsaw is most often due to the disadvantages that a factory-made one has hand tool. You can make a small one with your own hands table machine, which will include a pusher, a reciprocating motor, and a saw tension system. In this case, you do not need complex drawings - once you understand the essence, it is easy to achieve the result.
The desire to create homemade jigsaw may occur for several reasons:
- There is no power supply in the workshop, but it is possible to use low-power internal combustion engines.
- There are pneumatic motors, but the compressor power is not enough for a serial tool.
- The electric motor is powered by batteries or solar panels, the power of the source is not enough to use the power tool.
- It is required to obtain saw motion parameters that are unattainable using a commercial tool.
Designing a jigsaw is not difficult. A typical structure looks like this:
The installation is easy to adapt to any torque source. A pair of pulleys (one is located on the engine shaft, the other drives the crank mechanism) allows you to vary the gear ratio, reducing the load on the power unit and allowing you to get the required speed (they are also responsible for the number of saw strokes per minute) on the actuator.
A machine built according to the above diagram may have the most different configuration, the material of manufacture is also selected individually. Example ready installation looks like this:
Disadvantages of a manual jigsaw
The manual jigsaw is designed for shaping straight cuts . In this case, as the rollers, rod, and pusher wear out, the saw may wobble, deviate from a straight line, and change the angle of attack. Regardless of the quality of the tool components, the following features are always present:
- When the saw becomes dull, deviation from a straight line is observed when cutting material of uneven density (for example, low-quality chipboard). The saw is capable of leaving the cutting line when it encounters a knot in the wood.
- When trying to make a curved radius cut, you can observe the following picture: the upper cutting line, which the worker follows, follows an exact trajectory, the lower one deviates, goes to the side, the radius becomes larger. The higher the wear of the tool and the lower the sharpness of the saw, the more pronounced this phenomenon is.
- Some materials cannot be worked using a pick-up or bottom feed of the saw. The carpenter is required to move the tool forward extremely evenly, which is impossible to do very accurately; as a result, the saw runs out along the entry and exit path.
It is even more difficult to work with thin ones intended for figured cuts saws. If there is no practice, achieve good result quite difficult, especially on thick slabs or wood materials. Let's look at how you can make a carpenter's job easier and the result better.
Standard solutions
Machine from manual jigsaw done based on a simple table. This device is common and mass-produced; samples can be seen in the photographs below.
The mechanics of work are simple:
- The jigsaw clearly fixes the tool, ensuring that there is no influence of the human factor (the hand can move the jigsaw unevenly).
- The presence of a support allows you to move the device without deviations along the trajectory.
With the help of a table, jigsaws begin to cut in a straight line, but the capabilities of such a device are limited. If you remove the side fence and try to guide the workpiece, forming a curved cut, the same problems of saw deflection arise. The problem can be solved by using a simple saw, rigidly fixed with a pair of rollers. Making curved cuts is now convenient and fast. What homemade and industrial products of this type look like is shown in the following photos.
Tension devices for curved cuts
To perform very thin and precise shaped cuts, you can make a machine from a jigsaw with a saw blade tension system. The idea of creating it yourself is as follows:
- A very thin saw is used, ideally for a hand jigsaw.
- A clamp is attached to the rod of the power tool, which will tighten the cutting blade.
- The trajectory stabilization system will regulate both one freedom of movement and two (horizontal and vertical).
Used as a tension block hand jigsaw clamp, to which an adapter is made, which in turn is inserted into clamping fixture power tool rod. To ensure adjustment of one freedom of movement, a pair of angles and a bolt are used. The result of the idea implementation is presented on next photo.
The saw provides clearly vertical movement, you can create a good tension, but there is a mandatory runout in the horizontal direction. The canvas comes with a pick-up and does not move in a straight line.
The development of this idea is in the next photo. Here the part that fixes the trajectory moves, and the metal clamp provides structural rigidity and mechanical resistance.
The system is stabilized in two degrees of freedom, the cut made with its help is neat and precise. By using a diamond-coated cord for a hand jigsaw, you can cut glass without creating messy chips on the edges.
Accessories for extremely delicate work
If you need to act extremely delicately and slowly, you will need to reduce the force by cutting blade and at the same time ensure strong tension and precise movement of the file. For this, a homemade jigsaw is equipped with spacer devices with long shoulders.
In this case, the power tool does not operate in the cutting zone, but at some distance. This allows, depending on the wishes of the carpenter, to regulate the force, speed and amplitude of movement of the saw. One of the options for implementing the idea is shown in the following photo.
Depending on the needs of the master, the structure can be made of steel, have additional fixing zones, and the power tool cannot be installed rigidly, but with the ability to move within its support beam.
In practice, such solutions are rarely used. For delicate work that is performed constantly, it is much more profitable to purchase a specialized band saw, which will ensure quality and productivity.
As can be seen from the presented designs, a jigsaw can even be made from a sewing machine with a moving rod.
What if you need to use a jigsaw, but have no desire to purchase one? Experienced craftsmen They will answer that in this case the easiest way is to make a jigsaw with your own hands.
There are multiple ways to make and repair such a tool yourself. Below is a list of options for using the simplest and most accessible of them.
Making a manual jigsaw using simple technology
Before making a jigsaw, you should prepare inexpensive and available materials. Let's present them in the form of a list:
- sheet plywood - 12 mm;
- sheet plywood - 5 mm;
- sheet steel - 2 mm;
- set of bolts and nuts;
- drill (manual or electric);
- chisel;
- sanding paper;
- files.
As a base for a manual jigsaw, you must use a bracket, which is made from a sheet of plywood (12 mm).
After this, you should thicken the handle using a thinner plywood sheet (5 mm). This thickening is glued evenly on both sides of the handle, which ensures its comfortable position in the hand during subsequent work with a jigsaw. At the same time, the bracket and handle must be carefully processed using sandpaper and files of different classes.
The steel plate must be cut out using a chisel and the clamping jaws must be cleaned using a file. Next, you will need a drill to make slits in the jaws. Having taken this step, we begin to cut out notches on them with a sharp chisel. The left clamping jaw must be modified in such a way that it is done threaded hole for the bolt. We attach the jaws to the bracket, and then screw in the bolts on the left clamp, securely securing it with a nut.
Options for making a tabletop jigsaw
Desktop devices of this type can be made either from scratch or by modifying existing devices.
Option 1
To make a new benchtop mechanical jigsaw, you must first acquire the following tools and consumables:
- duralumin pipe;
- plastic base;
- screws;
- copper sheet;
- drill.
First, we prepare the frame; a duralumin pipe is well suited for this purpose. During the manufacturing process of the frame, a passage must be provided through which an electrical wire is laid, which will provide the tool with power. Using a copper sheet, a U-shaped frame is made, which is then attached directly to the frame. In the area where the frame connects to the jigsaw handle, the frame is screwed in with screws.
Then we take plastic base for drilling holes and mounting slots in it. We fix the jigsaw on the prepared base so that the file can pass freely through the hole. We attach with clamps ready-made device on a flat surface, such as a table.
Option 2
To make a jigsaw, you can use a sewing machine, the repair of which is not necessary. To make such a tool you will need following materials and tools:
- foot or manual sewing machine model;
- hacksaw blade;
- needle file;
- electric drill.
Unscrew from lower parts machine design, all bolted fastenings, all parts are completely removable working system with thread. We remove the metal fastening rod by knocking it out and remove the drive shaft. We unscrew 2 more bolts and disassemble the panel that covers the sewing machine; removing it is quite simple. Remove with gentle movements sewing needle and let's get to work.
First of all, we carry out work with the slot for the needle. We expand it to such a size that the file can fit there. A needle file will help you cope with this task. It should be selected based on the size of the hacksaw blade. Try to adjust the size of the slot for the file as accurately as possible. Having bored out the connector, you can install the blade in place of the former needle holder. And finally, when turning the wheel, you need to check a few things to:
- there was no contact between the saw, the panel and the presser foot;
- there was free passage of plywood under the saw in the upper position;
- the materials were drawn in a smooth motion without jerking.
These jigsaws are suitable for use with plywood, balsa wood and plastic, and when using an electric machine, such a device can be converted into a jigsaw.

If it is not possible to repair the jigsaw
If using a manual jigsaw is not up to the task, and electric jigsaws cannot be repaired, then you should use the options presented below that will allow you to make a jigsaw. Electric jigsaw table type:
- electric jigsaw for manual use;
- sheet plywood;
- set of clamps;
- 10 pieces of screws;
- electric drill.
We make markings for the slots in the plywood and carefully cut them out. If there is a pendulum stroke, it must be turned off. Then we place a hacksaw blade in the slot and attach it there. We also make several slits on the plywood by drilling holes with a drill and connecting them to each other. Screws are placed in the slots made. As a result, securing the tool with clamps on flat surfaces will not be difficult. The device is ready.
Jigsaw from an electric drill:
- steel sheet (4 mm);
- steel sheet (1.5 mm);
- steel sheet (1 mm);
- steel rail (2 mm);
- spring rail (0.9 mm);
- steel rod (7 mm cross-section);
- electric drill.
Using sheet steel (4 mm), we make a product in the form of a C-shaped frame, which will be the base of the jigsaw. Next, attach it to an electric drill. For this purpose it is necessary to create special clamp made of steel sheet (1.5 mm), which will ensure fastening. We attach spring slats to the edges of the base. Steel sheet(1 mm) we will need to make clamps with which the saw will be attached. Clips like these on the edges will also help strengthen the C-frame. And from a steel rod you can make a crank that will power the saw. For the connecting rod we need a steel strip, which will allow us to create a crank mechanism.
At this point, the work on making the jigsaw can be considered complete. Due to its massive size, for safety reasons it is better to clamp the drill in a vice while working. And it’s best to place working materials on flat surfaces.

Carving and sawing beautiful figures from wood is a fascinating activity. A person’s inclination towards this creativity manifests itself from early childhood and often remains throughout life. Everyone knows that this is difficult and rather painstaking work. It always requires not only special care, but also a lot of time. To eliminate this drawback and make your work easier, you need to automate the process. To do this, you just need to purchase a jigsaw in the store. However, such a device is not cheap on sale and not everyone can afford it. But this problem is easy to solve if you make a device for sawing and carving wood yourself.
For this you will need materials:
- drawings or diagrams;
- wooden blocks;
- short boards;
- pieces of old plywood;
- simple nails or screws.
Tools:
- medium sized hammer;
- regular hand saw;
- small plane;
- jigsaw;
- sharp axe.
Scheme or drawing
Before you begin assembly, you need to draw a diagram or make a drawing of the jigsaw yourself. With their own hands, rarely does anyone manage to complete a high-quality document on a good professional level, but it doesn't matter. You can always find a suitable drawing on the Internet and use it to assemble your jigsaw. Often for simple homemade device inventors use only a mini-circuit, simply drawn by hand. This is quite sufficient when you need to construct a simple device for figure sawing from plywood and wood.
Stationary option
There are often times when it is necessary to make perfect cuts in plywood or wood strictly vertically. This kind of work is simply impossible to do even with a factory jigsaw. A device that is always in your hand will produce deviations, and the edges of the slots will never be perfectly shaped. To make them straight and even, such work should be done only on a stationary machine, where the device for sawing in wood or plywood is firmly and securely fixed to the table surface.
To design a stationary jigsaw for figured cutting on plywood and wood, you must first prepare the material for building the table. It will provide a strong support for the machine and will also provide ease of use. All this is easy to make from wood. First you need to find suitable bars, mark them and make a table frame from them. After this, cut off identical boards, lay them on top and secure them with ordinary nails or screws. To ensure that the surface is sufficiently smooth, it is advisable to lay plywood on the table. It will not only make the surface smooth, but also create additional rigidity.
Next, you will need to install the unit itself for figure sawing from wooden blanks. Of course, you can make the entire mechanism out of plywood, but it will take too much time. The easiest way is to use a very simple method, where a standard factory device is installed to operate the saw - a jigsaw. To do this, you only need four small corners and a few screws. And then everything is done very simply: find the center of the table and drill hand drill hole through. Its diameter should be such that a standard factory file can pass through it freely. electric jigsaw.
When a file is inserted into this hole and the entire device lies tightly on the table, you will need to draw a pencil around the duralumin support. Then use a jigsaw to cut a hole so that the body itself fits through it upside down, and its support bar sits tightly at table level. All that remains is to place small corners at the bottom and secure the platform with screws. At this point, the stationary jigsaw machine is considered built and you can safely begin work.
Sewing machine equipment
Today, many inventors successfully use modern methods, which differ good quality and precision in work. Particularly notable is the jigsaw machine using a band blade. However, despite the very high speed, not everyone can do it. For this reason, it is worth choosing a simpler method using an outdated sewing machine. Although her device has already served its useful life, it still needs to work homemade machine it won't affect. In addition, this is a fairly common and inexpensive option, where too much expense is not required.
For this homemade design machine you will need:
The construction of a table for a stationary jigsaw was discussed above, so we will not consider it further. But it is worth noting that a workbench can be perfect for these purposes. In addition, many old sewing machines already have a table-like design, as well as a mechanical drive. Therefore, here we will analyze only the main mechanisms that need to be changed.
Rework
Converting an old sewing machine into a tabletop jigsaw is not too difficult. First you will need to change the rear mechanical part where the needle is secured. To do this, you need to file the shank on the side so that a standard blade from a factory electric jigsaw fits freely into the clamp. The hole in the bottom plate, which is intended for the needle, also needs to be enlarged. This is easy to do with a hand drill with a diameter slightly wider than the file.
Often the clamping foot on a sewing machine gets in the way when cutting thick plywood or wooden blocks. It is easy to remove by unscrewing the side locking bolt with your hands or a screwdriver. As the jigsaw works, sawdust will remain. They are easy to assemble if you place a small box underneath. But before that, you have to remove the shuttle along with the entire device that will interfere. Removing it is easy with just a small adjustable wrench or pliers.
Mechanical drive and motor
It is clear that turning such a machine by hand will be very difficult and inconvenient. Therefore, it is necessary to install an additional motor with a mechanical drive. Literally all samples sewing machines They have a pulley in their design. A motor is connected to it using a belt, which is turned on with your foot. If such a unit is not available, then it is not difficult to make it yourself. To do this, you just need to find an electric motor of suitable power. And then firmly attach it to the table using simple clamps- and you can actively get to work.
