Jigsaw table. How to choose a tabletop jigsaw: rating Do-it-yourself jigsaw

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 a maximum voltage of 220 V. 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 start installing power cable and connecting 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. The optimal installation distance for the central unit is 14 cm. At the same time, the average platform width is 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 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

It’s quite easy to make a 3 kW desktop jigsaw with your own hands. 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 are long and 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.

A jigsaw is a tool without which it is now simply impossible to perform many works on processing wood and materials in which it is used. Being compact and light in weight, a handheld portable jigsaw is capable of cutting out products of very complex geometry from a workpiece.

The jigsaw is very convenient to use and also provides very precise and thin cut. If you don’t want to spend money on a purchased jigsaw, you can make your own at home.

The lightest product

The jigsaw table itself can be made with your own hands in a short period of an hour. The advantage of the manufactured design will be its simplicity. It can easily be mounted on a tabletop or workbench and, if necessary, can also be easily disassembled. Disadvantage homemade design can be considered its small area.

The simplest product consists of the following parts:

1. Plywood.
2. Mounting screws.
3. Clamps.

The working basis of the machine can be laminated plywood, in which it is necessary to drill holes for installing fasteners and for the saw itself. Plywood must be at least 10 millimeters thick. At the same time, you may also have to make holes in the base of your power tool for mounting screws.

A homemade structure can be attached to the workbench using clamps. Please note that the heads of the screws for fastening must be recessed into the surface of the sheet so that they do not interfere with you while working. Such a machine can easily handle the processing of small workpieces up to 30 millimeters thick. You can easily find a drawing of this type of machine on the Internet, and then assemble it yourself at home.

Another variant

This option consists of the following parts:

1. Bed made of chipboard.
2. Tube for vacuum cleaner.
3. Laminated plywood for the machine cover.
4. Confirmants.

There is a second option for a stationary device for working with wood material, which is assembled from a larger number of spare parts, but making it is not difficult. The frame is made of chipboard and consists of a back wall and two sidewalls. To make it easy to get to the power button, the machine has no front wall.

IN back wall do it yourself drill holes for the vacuum cleaner tube and cord. The cover for the machine can be made from laminated plywood 10 millimeters thick. The entire structure can be tightened with confirmants. The jigsaw can be secured in the same way as described above in the first case.

On a machine made according to this option, it is possible to process more massive workpieces, however, when working with a thick workpiece, the jigsaw saw can go in both directions and lean back. At the same time, cutting accuracy deteriorates. This drawback can easily be eliminated with your own hands by installing a bracket on a homemade machine that will serve as a stop.

The jigsaw blade will move between two 11mm bearings, which must be screwed to an L-shaped strip made of steel. The back of the saw will rest against the wall of the bracket itself. This design will prevent your jigsaw blade from deviating from the intended path.

The bracket must be attached to the frame, made of 50 by 50 millimeter bars. It can be lowered or raised depending on the length and thickness of the wood being processed. To do this, the frame itself, together with the stop, must not be firmly attached to the side of the machine, but pressed against it with a hardboard, steel or textolite plate. Install vertical stand frame between the hardboard and the frame.

The machine can be more convenient if you mount an additional limit bar on it, with which you can cut the material into workpieces of the same length and thickness.

The limiter is attached to the machine using clamps. His made from wooden beam , aluminum or steel corner. For convenience, you can also install a bar on the slide, which must be secured to the sides or bottom of the tabletop.

Table for a jigsaw made of chipboard

To make this jigsaw table, you must have a certain carpentry skill, since when connecting its frame to the legs, it must be made into a tongue and groove. The tongue and groove itself can be replaced with a connection using dowels, wood glue and self-tapping screws.

The machine cover must be made liftable to facilitate access to the tool when replacing it. In order for the machine to be multifunctional, it is necessary to provide space for mounting a manual milling machine.

The table is assembled from the following materials:

• block 80 by 80 millimeters;
• block 40 by 80 millimeters;
• laminated plywood or chipboard measuring 900 by 900 millimeters.

Measure the distance between the legs, it should be from 60 to 70 centimeters. The bars for the legs and drawers will be obtained if you cut the bars lengthwise 80 by 80 millimeters. You can choose the height of the legs themselves at your own discretion, it all depends on how comfortable it will be for you to perform work on the machine.

At each end of the legs and drawers, it is necessary to drill two holes for dowels. The same holes must be made on the sides of the legs. Coat the dowels with glue half their length and insert them into the ends. After this, assemble the entire frame. It will turn out to be non-separable. After checking and possible corrections, it is tightened tightly.

All surfaces at contact points must be coat with glue. Use self-tapping screws for additional structural strength, which must be screwed through holes prepared in advance for them.

The cover must be attached to one of the drawers using hinges; to do this, a slot must be made in it to facilitate removal and installation of the jigsaw. In the back of the tabletop, you need to screw two strips with a pre-selected quarter into which the sole of the power tool should fit.

Holes must be made in the strips, into which bolts or clamping screws must then be installed. A jigsaw mounted under the tabletop will be able to cut thicker material if a recess is made in the lid for its sole. The easiest way to make this deepening is using a milling machine.

The resulting table will be very simple and spacious, so the necessary strength of its lid can be provided by a large thickness of chipboard or plywood. Use sheets of 20 millimeters or thicker.

Jigsaw using thin saws

Since when cutting complex patterns in plywood, a jigsaw is not well suited for this, you need to take a thin file. It can be attached to a hand-held power tool using the original tool.

We also attach the jigsaw to the tabletop, but the thin file needs to be tensioned, since it will not be enough just set on a pendulum. To facilitate the process of tensioning the file, it is necessary to make a rocker arm from a block.

The tension of your canvas is ensured by a spring. Place its lower loop on the transverse pin. The upper loop must be inserted into the adjusting screw, which changes the tension force of the damper. All wooden blanks for a homemade machine are made from hard rocks tree.

Since the jigsaw machine does not have the ability to fasten a blade with a thin section, you can remake the piece old saw, having previously drilled a hole in it and completed it with a screw with nut and clamping plate.

A vertical slot must be made in the rocker arm into which a second steel plate must be inserted. It is attached to the rocker with screws. The upper part of the file must be attached to it in the same way as the lower one. To make it easier for you, you can use scraps from an old jigsaw to make the plates.

The desktop jigsaw machine is designed for cutting various parts having a complex configuration, made of sheet materials. This tool is capable of working with MDF, chipboard, fiberboard and many others. Jigsaws can also cut out the internal contours of parts if you first make a small hole. This tool has a wide range of applications, since it can provide high performance labor, which cannot be achieved with a regular hacksaw.

Design features

The design diagrams of all jigsaw machines are usually the same. Having carefully examined the drawings where this tool is depicted, you can see the following structural components:

• the bed, which is also often called the body. It is designed to accommodate everyone structural elements unit;
• drive mechanism;
• crank mechanism. It is necessary to convert the rotational energy of the motor shaft into the movements of the saw used during operation;
• double rocker arm. Equipped with fasteners for a file and a tension device;
• Desktop. In some modern models it has a rotation mechanism that moves at a given angle.

How to make a machine from a jigsaw?

To make a jigsaw from a manual jigsaw, you need to follow these instructions:

1. First you need to make a table where a homemade jigsaw will be installed in the future. To do this, use any durable sheet material - thick plywood, metal and others.
2. They do it in the table through holes, designed for cutting blades and various fasteners.
3. The resulting jigsaw table is installed and securely fastened to a suitable wooden table.
4. The resulting table is equipped with guide rails.
5. A manual jigsaw is attached below, which makes it possible to replace the drive mechanism of the machine and many of its other structural elements.

Anyone can make such a jigsaw machine with their own hands. Its advantage is that at any time this unit can be quickly disassembled and only hand tools can be used.

Homemade jigsaw table machine from a manual jigsaw

How to make a more professional instrument?

A homemade jigsaw machine can have all the qualities that are present in professional equipment. To make it you need to follow these instructions:

1. The frame is made from any durable material - 12 mm plywood, plastic, textolite and others. It should consist of a base, a housing to accommodate all structural units and a work table.
2. On the other side, a rocking chair with an eccentric is placed. They need to be connected to each other using metal plates with sleeve-type bearings. The resulting structure is installed using screws.
3. The intermediate shaft is formed from several bearings.
4. The metal pulley is placed very tightly on the shaft and the screw connection is secured.
5. To change the movement characteristics of the rocker, 4 round holes with threads are made on the eccentric flange. They should be placed at different distances from the center line. The amplitude of movement of the rocking chair is regulated by the location of the screws.
6. The rocking chair is formed from wooden rocker arms, which are attached on a hinge to the stand.
7. Small cuts are made at the rear ends of the rocker arms. They are designed to install tension screws.
8. The front ends of the rocker arm are designed for mounting a saw blade. It moves using special metal hinges. Before attaching the file, it is installed in a groove located on the work table.
9. The rocking stand is made from a single piece of durable material. At its upper end a groove is made for installing the rocker arm, and near the lower end a small rectangular hole is cut out for mounting the second rocker arm.

How to make a machine from a sewing machine?

A sewing machine makes an excellent jigsaw, which is equipped with a saw blade movement regulator. It is not difficult to do if you follow these instructions:

1. The thread weaving mechanism is removed from the bottom of the machine. On some models it may be located in a different location.
2. To dismantle this unit, you need to remove several bolts, then remove the cotter pin and drive shaft.
3. The top protective panel is unscrewed. After this, the groove along which the sewing needle moves must be expanded to suit the parameters of the file.
4. The cutting element itself is also slightly modified. It is trimmed according to the length of the sewing needle.
5. It is not necessary to make an adapter to install the cutting element. Instead, you can grind down the upper incisors a little and process the lower zone of the blade.
6. The file is inserted into the needle holder and work begins.

All presented options for manufacturing jigsaw machines are very successful. The resulting units are distinguished by high labor productivity, and making them is not at all difficult. Depending on their skills, each master will be able to choose best model homemade equipment.

Video: Jigsaw from a sewing machine

The process of shaped or straight cutting of a large volume of materials, even of small thickness, can be very energy-consuming and time-consuming. In this case, a more advanced, stationary analogue, which has the necessary characteristics for reliable work, replaces a conventional hand jigsaw. In this article we will look at how a jigsaw machine works, what characteristics it has and how wide the functionality it can have. Also, at the end of the publication, we will provide a rating of high-quality, inexpensive models suitable for amateur and professional use.

What is a jigsaw machine

A tabletop jigsaw is a powerful device for longitudinal and shaped cutting of wood and other materials of small thickness. It consists of a rectangular base with a working surface and a rigid, metal frame. An electric motor located at the base transmits movement to the saw using the principle of a crank mechanism. The operating principle of a jigsaw machine resembles sewing machine, which became the prototype for the creation of this device.

The scope of application of a stationary jigsaw is as similar as possible to its more primitive manual ancestor, except that the first is used for more professional work. If we ignore the obvious design differences and focus only on the capabilities of the devices, we can highlight several significant features.

• When working on a jigsaw, unlike a manual one, the operator has both hands free, which allows more precise control of the position of the product during cutting.
• The effectiveness of using a manual jigsaw depends on the skill and physical data of the person. Prolonged work with such a tool is significantly exhausting.
• Most models of jigsaw machines are equipped with a tilting working surface, which allows you to cut the workpiece at a certain angle. Accurately performing such a task manually requires some experience.

Files for a jigsaw

The most important working element, which requires the most frequent replacement during operation, is the saw blade. The duration of its use and the quality of the final result depend on the characteristics of this consumable. To work on a jigsaw, files with flat ends are used. Unlike a manual jigsaw, blades for the machine have pins installed at the ends for more convenient installation and tension. Otherwise, the files installed in a manual and stationary jigsaw are identical in size and shape.

We have provided a more detailed description of the types of saw blades for a manual jigsaw and a selection guide in a separate publication on our website.

Main characteristics

There are several generally accepted indicators that determine the capabilities and efficiency of a jigsaw machine. Before choosing a device based on certain data, you should set clear criteria in advance and determine the approximate scope of work in which an electric table jigsaw will be used. It’s worth answering whether you need a powerful and expensive machine capable of cutting thick bars and sheets of metal, or will it be enough budget option with high speed cutting of small workpieces. The more specific the answer to this question, the more profitable purchase you can make. To select the most optimal device, we provide the following data.

Power

One of the most important indicators affecting the operation of an electric jigsaw is the power of its motor. The higher its value, the thicker and denser materials it can cut. The average power rating for models costing up to 10,000 rubles is only 90 watts. Compared to normal electric jigsaw, where the average value is 450 Watts, the indicator of the stationary analogue does not seem serious, but in fact, this power is enough to confidently cut wood up to 50 mm thick.

Although the power indicator plays important role When purchasing, in order to understand how to choose a jigsaw machine that meets your requirements, you need to understand the remaining characteristics.

Cutting depth

Another important indicator that determines the maximum thickness of the material being cut. In most cases, the maximum value for wooden workpieces is 50 mm. Basically, this thickness is determined design features a device whose frame simply physically does not allow placing a larger product underneath it. At the same time, when it comes to working with metals or plastics, the power indicator at the cutting depth plays a key role. Average values ​​in budget models are 6 mm for steel and 15 mm for PVC.

Number of moves

Meaning this parameter determines the speed and accuracy of cutting the workpiece. The more reciprocating movements your machine makes per minute, the fewer chips are formed on the wood, and the cut line is smoother. Average number of moves for most stationary jigsaws costing up to 10,000 rubles is 1,500 per minute. When using special saw blades (double cut), this value is sufficient to obtain a clean line.

If you intend to produce high-quality products and you need a good tabletop jigsaw for artistic sawing, you should pay special attention to the frequency of the saw blade. The higher this indicator, the better.

Desk dimensions

The convenience of working with large workpieces depends on the size of the work table of a jigsaw machine. This indicator does not determine the maximum cutting length (this is indicated by the clearance to the frame), but it significantly facilitates the manipulation of large sheets of materials. The average size of the working table of budget stationary jigsaws is approximately 350 mm in length and 250 in width. You should pay attention to the dimensions of the site if you plan to work with materials large sizes.

Additional functionality

The presence of additional functionality expands the capabilities of any device, and a jigsaw is no exception to this rule. Special regulators and accessories make the device more versatile, increasing its cost, but at the same time, labor efficiency. For the convenience of performing certain operations, stationary jigsaws for wood are equipped with a pedal, a backlight, a dust collector, a mechanism for tilting the work table, and even an engraver. Let's take a closer look at all the delights of modern jigsaw installations.

Speed ​​adjustment

One of the most common additional functions, most often found in desktop jigsaws. Adjusting the speed allows you to adjust the frequency of reciprocating movements made by the saw blade in one minute. This function makes the device more versatile, allowing you to high-quality cut materials of varying degrees of density. For example: with wood and its derivatives, you can work at maximum speed, for PVC is better set the average value, and it will be more correct to cut metal at minimum speed, to extend the life of the saw blade.

There are two types of speed controller: smooth and stepped. The first type allows you to set the most precise frequency of movements, and with the help of the second you can only switch between several speeds provided by the manufacturer. Both options have a right to exist, but in the case of the second, it is worth paying attention that there are at least 4 speeds. Sometimes you come across models of jigsaw machines with a speed controller of only 2 speeds, which does not particularly expand the capabilities of the device.

Work surface tilt

When a product requires cutting at a certain angle, the tilting function of the working surface comes in handy. This mechanism allows you to set the required angle of inclination of the desktop, up to 45°. In most budget models table jigsaws the tilt is carried out only in one direction. In more professional devices, this function works in both directions. The ability to set the cutting angle in modern machines is becoming more and more common, but there are also models where it is absent.

Backlight

The cutting process is much more efficient in a room with good lighting. If it is not possible to illuminate the entire room brightly enough, built-in lighting comes to the rescue. This simple function, provided in some models of jigsaw machines, greatly facilitates the work process, saves vision and saves time that you could spend on organizing the lighting yourself. working area. Of course, this function is not decisive in choosing a stationary jigsaw, since you can do it yourself if you wish, but a neat spotlight will be an undoubted advantage of any model.

Dust extraction

When cutting, even a small volume of material, a fair amount of sawdust forms on its surface. In addition to the fact that this waste from the work process covers the contour being sawed, due to the vibration of the machine, it partially enters the air and the operator’s respiratory tract. In order to ensure a comfortable working process without dust and shavings, many models of stationary jigsaws are equipped with special dust extractors, to which you can connect a vacuum cleaner to suck up sawdust.

An additional option for removing sawing waste is a flexible rubber pipe. This element is connected to small compressor, and unlike a dust extractor, it does not suck in dust, but blows it away in the prescribed direction. It is better to wear a respirator when working on a machine with a similar function. Many models of tabletop jigsaws have both sawdust removal functions at the same time.

Flexible shaft (engraver)

One of the most interesting and useful functions, in most cases inherent in professional models. Allows you to drill, grind and polish products without the use of third-party tools. The main advantage of a flexible shaft is the almost complete absence of vibration. Among the disadvantages, we can note a single drive that starts the saw blade and the engraver at the same time. For safety reasons, when working with a flexible shaft, the saw blade should be removed from the fastening element. The average number of revolutions of the nozzles per minute is 2500, which can be reduced or increased using the speed controller.

Rating of desktop jigsaws

Among large quantity of the products offered, it is quite difficult for an inexperienced buyer to make an unambiguous choice of a tool that meets all the requirements. By and large, this statement applies to such technologically complex devices as jigsaw machines. When choosing of this device, it is necessary to have clear requirements for technical specifications and additional functionality. In addition, it is worth reading reviews from previous customers, comparing people’s opinions with your expectations.

To make the selection process easier, we have collected 5 proven models of budget jigsaw machines costing up to 10,000 rubles. The devices listed below belong to the budget category, but they cope with their task 100, or even 150 percent.

If you are engaged in carving and make figures or parts from wood, plastic or similar material, you cannot do without a tool whose name is reminiscent of the distant Soviet past: a jigsaw.

Jigsaw is different from jigsaw, now there are also “pioneer” elementary ones on sale manual models, and electrical modern instruments, only vaguely reminiscent of the usual files.

You can make a jigsaw yourself: technical literature and the Internet offer many diagrams and drawings of electric jigsaw machines.

Making such a device is not difficult, and you will get significant benefits from it. You will be able to independently produce the furniture you need and realize the most daring creative ideas for interior.

An example of manufacturing a jigsaw machine.

A homemade jigsaw allows you to professionally make smooth parts of the most bizarre shapes. First, you need to decide on the design that is most suitable for you.

Technical description and components

The schematic diagram of any jigsaw machine is the same for different models.

It must contain the following parts:

• file;
• drive with a power of about 150 W;
• rocker for tensioning the file;
• working surface with graduation;
• drilling block, etc.

Consumables are fixed on the working surface. In advanced models there are special devices for rotary movements of the part, in which the working surface can change the angle of inclination.

The size of the surface will depend on your production and creative plans: the larger the part you are going to cut, the larger your production table should be. Traditional sizes are usually around 30 – 40 cm.

There are a wide variety of types of files. They depend primarily on consumables. The dimensions of the parts for cutting also matter. Conventional saws for working with wood have a length of about 35–40 cm. They are able to saw parts made of wood or plastic with a thickness of no more than 100 mm.

WITH different types The materials also change and the files also change, mainly in relation to their width: from 2 to 10 mm. Files can differ in the type of their tails - with or without pins. They are fixed in a special device for tensioning them and smooth sawing. For this purpose, they have springs of a spring type.

Another important one: the crank assembly. Its function is difficult to overestimate: it is it that transmits movement from the drive to the saw, turning rotational motion into translational motion.

Assembly drawing of a jigsaw machine.

Due to this, the file begins to oscillate at a high frequency, the speed of such oscillations is on average about 800 - 1000 revolutions per minute. It is important to remember the amplitude of vertical vibrations; it should not exceed 50 mm.

In advanced modern jigsaw models, the speed varies depending on the type of consumable. Most of desktop models operate in two speed modes. Most often these are 600 and 1000 rpm.

Model range of jigsaw machines

Most often, in the power of an electric drive, the range of values ​​is huge: from 90 to 500 W.

These devices are also divided into varieties based on their fundamental design:

• universal;
• on suspension;
• with graduation;
• with the caliper in the lower position;
• with double caliper.

Jigsaws with lower support

Diagram of machine design elements.

The most used and popular models are machines with lower support. Their feature is the division of the working bed into upper and lower parts.

If in the upper section there is only one device for sawing and cleaning, then in the lower section there are many working elements: an electric motor, a switch, a transmission unit and a control unit. This design makes it possible to saw sheets of materials of almost any size.

Double slide machines

A homemade jigsaw with a double support differs from the lower support by the presence in the upper section of a special additional bar and a work table with the ability to change the angle of inclination and overall height.

These models are designed to work with parts oversized. This machine is easier to make than the previous model. There are restrictions on the materials that can be worked with: their thickness should not exceed 80 mm.

Hanging machines

The name speaks for itself: the model is movable, it works without a stand. The fundamental point in this design is movement. cutting file, not a consumable. The module itself is attached to the ceiling, the saw is driven manually.

All this provides serious advantages: in this way you can create the most complex patterns, the surface dimensions are not limited in any way.

Devices with graduation

The presence of stops and a degree scale make it possible to work according to technical drawings, without the slightest error.

Universal machines

Such devices are usually called jigsaws. Their feature is the ability to perform several operations such as grinding, polishing, sawing, etc.

How to make a jigsaw machine with your own hands?

We will not dwell on the manufacture of simple machines: you can easily find this kind of manuals with video support on the Internet. Let's talk about homemade machines from a jigsaw.

Do-it-yourself machine assembly.

Here is the sequence of work for their manufacture:

• We make a bed from plywood sheet or plastic.
  The main thing is that the thickness is at least 12 mm. The function of the bed is a foundation, a working surface and a place for fixing mechanisms and an electric motor.
• We place a special rocking chair with an eccentric on the opposite side.
  We connect them using a metal strip with bearings. All fastenings in the structure are screw.
• We install the intermediate shaft.
  To do this, you need to prepare two bearings, place the pulley on the shaft as tightly as possible, then carefully secure it with screws. Similar actions are performed with the eccentric.
• On a rocking chair, the range of motion should change.
  To do this, you need to change the mounting location of the screw, for which we drill exactly four threaded holes on the eccentric flange. The holes must be located at different distances from the axis. With a change in the mounting location of the screw, the amplitude of the rocker will change.
• We make a rocking chair: these are nothing more than wooden rocker arms, into whose rear ends the screws that you made in the previous paragraph are inserted, these are tension screws.
  The rocker arms themselves are attached to the rack with hinges. We fix a file to the front ends of the rocker arms. Previous and given stages must be done with special attention and thoroughness. The fact is that fastening the file is fundamentally important thing. Rocker arms with plates are subject to constant loads during movement due to their rigid connection with screws.
• The rocking chair requires a stand.
  It will be better if it is made from a whole piece of material. We make a groove for the first rocker arm on the top of the rack. At the lower end we place a special rectangular opening for the second rocker arm.

Yours. We wish you great ideas and their high-quality implementation.
