How to make a homemade jigsaw with your own hands from an ordinary electric jigsaw. DIY desktop jigsaw What can be done from an old jigsaw

This article will focus on the design homemade machine from a household electric jigsaw. The following will be 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 of the countertop, to quite complex structures with guides, the possibility of sawing at an angle, when it is possible to set not only 90 degrees to the base, but change the angle (well, within reason, of course). There are devices (machines) for, that is, making a straight and even cut.

Such devices are increasingly being used because of their versatility and functionality. In fact, they are similar in parameters and purpose to stationary machines and have a strictly defined practical use in every workshop.

Purpose

Preparatory stage

• draw up sketches and make a drawing of the future product,
• make paper patterns of future elements and details
• stick templates on the blanks of future parts.

There are two ways to make templates - take a tracing paper and draw on it the kennels of the future workpiece. This has been done since ancient times, since nothing is needed for this, except for a ruler and a pencil. However, if you have a computer and a printer, it would be nice, of course, in A3 format, 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 a ruler can be replaced by drawing the outlines of blanks on a computer.

Then cut out with a clerical blade or just a sharp knife.

After that Once the template is ready, it must be glued to the workpiece.

Tip: You don’t 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 stick, for example, on stationery glue, use glue stick or, as in our example, glue in the form of a spray.

Create blanks

On this stage need to do:

1. Cut blanks exactly according to the template,
2. Process workpieces - align the ends, remove burrs
3. Drill the necessary holes;
4. Make grooves with a file;
5. Drill seats for bearings;
6. Select grooves with a milling cutter for the cover and seat;

We install the bracket. It should be noted that the mounting of the bracket must be done without excessive tightening of the nut - there must be free play. To do this, use a self-locking nut and only slightly tighten it.

Installing the spring shouldn't be difficult. You need to do as shown in the photo below.

For the future fastening of the file, you need to make a simple clip 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 seat the fact that the bracket is moving, and the clamped plate will restrict its movement.

Below is a sketch of the design of the upper attachment of the file.

Then it is necessary to make technological holes for the controls of the jigsaw, so that it is convenient to change the engine speed, you can access the start button and its lock. There is another solution that allows you to make it more convenient to turn on the tool - this is to place an outlet and a switch in an easily accessible place on the machine body, which would turn the power on and off in the outlet. We plug the cord of the jigsaw into the outlet, 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.

Here are the controls that are now available.

Now you need to make clips for the file itself. The principle is simple - we take a bolt and make a cut at the base of the cap, but not completely. 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 assembly of the saw blade is mounted and assembled.

The lower node is almost the same as the upper one, except that it is not a plate that is used, but a standard file is taken (it can be “BU”), almost the entire cutting part is sawn off with a grinder (angle grinder) and the shank is left. In the remaining cutting part, a hole is made with a similar bolt with a slot at the base of the cap, which will also include a file. The principle is shown below.

After the file is fixed, we install the jigsaw itself. We fasten it with the help of bolts with countersunk hats so that they do not stick out on the tabletop of the machine.

Now you 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 bar that is exactly trimmed. We make the adjustment as follows. To adjust the file to the left / right, the adjustment of the upper plate is used - its displacement on the axis - respectively in the desired direction.

And to adjust the file position forward / backward, the displacement of the file attachment itself forward or backward is used.

The machine is almost ready, it remains to make and install a plate that surrounds the jigsaw file. It can be made from textolite or any piece of sheet plastic.

This completes the manufacture of the jigsaw machine.
We hope that the presented material was useful to you.

Desktop jigsaw is an indispensable thing for any owner who is accustomed to independently cope with household chores. Especially electric jigsaws are good for residents of the private sector, lovers manual labor and summer vacation. From its prototype, an ordinary manual jigsaw, the desktop electric model has gone far enough. A desktop jigsaw makes it easier and faster to cut, not to mention improving quality.

The concept of desktop jigsaw

The jigsaw is a saw, which is characterized by reciprocating movements of the saw blade, which acts as a working body. It has a ski designed to guide the saw blade when moving over the surface that is being processed, and making movements at a frequency of up to 3000 vibrations per minute.

This tool was invented in 1946. Its creator is Albert Kaufman, who replaced the needle in sewing machine on the blade. The tool appeared on sale in 1947. The manual electric jigsaw has a body with a flat platform and a handle. The main difference between an electric jigsaw and a manual jigsaw is its greater functionality and cutting quality.

Located inside Electrical engine and a special mechanism that drives the blade. IN stationary jigsaws there is no handle, and the platform is located on top. In front of the mechanism there is a guide, in the lower part there is a retractable blade that moves and makes cuts.

The tool works as follows: a table jigsaw file is securely fastened with clips in the slider. Reciprocating movements have a frequency of up to 3000 strokes and can be adjusted. The support platform allows the jigsaw to focus on the part being cut, so the work is carried out very accurately.

The purpose of the desktop jigsaw

The jigsaw is an essential accessory for every workshop and every hobbyist. His thin file can successfully cut plywood, copper, iron, thick boards, brass, steel. Instruments can be with motor, foot or manual drive and differ greater productivity. An electric jigsaw is simply indispensable for carpenters, woodworkers, furniture designers, drywall workers who make complex parts.

An electric jigsaw can perform straight and curved cuts on workpieces with complex shapes and various sheet materials without disturbing the external contour. Most often, desktop jigsaws are used for cutting wood and wooden boards, figures with a complex outline of laminate and drywall, plastic blanks, also for cutting sheet metal.

Desktop electric jigsaw makes clean cuts of complex shapes and works with small
details. Due to the stable and fixed position during operation, high cutting accuracy is achieved. The file has a stable course thanks to the tension system and guides, which manual jigsaws lack. The large size of the table makes it stable, so that a precisely defined sawing direction is observed.

Types of jigsaws

Today, a wide variety of electric jigsaws are presented on the power tool market, which differ in the nature of the application, technical specifications, type of power supply and design features. IN construction stores you can buy a desktop jigsaw for every taste and budget.

By design features, it is difficult to classify, because each manufacturer seeks to provide its products with features that are designed to facilitate and improve the operation of the tool. In this regard, the shape of the handle is an important parameter.

Two types of handles have settled - mushroom-shaped and D-shaped. A jigsaw with a staple-like handle requires one-handed operation. This increases the possibility of using a jigsaw, but somewhat negatively affects the quality of the material cut.

Mushroom handles allow for more accurate cuts when holding the jigsaw with both hands, after fixing the workpiece to be cut. The choice of a jigsaw with a certain shape of the handle depends on the financial capabilities and personal preferences of the buyer. It is worth choosing the jigsaw with which it will be more convenient to work.

Household jigsaws are not intended for intensive use, but the low price of a desktop jigsaw and the power that is enough for domestic needs make them indispensable in the household.

Professional jigsaws are characterized by high wear resistance and the possibility of many hours of daily use (up to 8 hours). The significant power of such jigsaws allows you to process materials of great thickness. Extended equipment and improved features are reflected in the price.

Among professional jigsaws, industrial ones also stand out, which are characterized by greater adaptability to complex operations and drive features - for example, increased power supply voltage. Industrial models are machines that are designed for the woodworking industry.

By type of power supply, there are network and battery electric jigsaws. Network models are powered by a standard voltage power supply. If performance is important to you, then you should choose a corded power tool.

Cordless jigsaws provide independence from the presence of sockets and greater mobility during work. When buying a battery model, you should pay attention to the type of battery. Increased performance is inherent in lithium-ion batteries. Battery capacity is responsible for the duration of work without recharging.

Advantages of desktop jigsaws

Desktop electric jigsaw is fixed structure, so this cutting type The tool has many advantages. Modern models can work with wooden materials 40-50 mm thick. A narrow saw acts as a working body, which performs vertical reciprocating movements. Due to the peculiarities of the notching of the teeth and the mechanics of the movements of the file, the material is cut out by moving upwards.

The desktop electric jigsaw allows you to cut out complex decorative details, to make longitudinal, straight, oblique and transverse cuts. The wide tabletop allows you to process large parts and make cuts inside wide workpieces. Reliable fastening protects the body from unnecessary vibrations and allows you to well position the material, so the motor can work without overloading.

The advantages of desktop jigsaws include good accuracy and clarity of cuts, high safety and ease of use, wide opportunities settings from the material and the required detail of the cut blanks.

If you need to cut small parts, a manual jigsaw will not be very convenient. It is quite heavy, so you have to hold it with one hand and guide the workpiece with the other. And the desktop jigsaw is devoid of this drawback. Perhaps the inconvenience is too big sizes and the difficulty of working with large parts.

The desktop jigsaw is a kind of mini-machine for cutting workpieces. If you buy a jigsaw in a store, most likely there will be an opportunity to select the power and adjust the frequency of the saw strokes. However, you can make the simplest homemade desktop jigsaw, and very quickly. You will need a manual jigsaw, a few screws, a piece of plywood small sizes and only one hour of work.

Making a desktop jigsaw

A carefully made jigsaw will not be inferior to a factory-made one, and in some respects even surpasses it. It is not difficult to assemble such an electric jigsaw if there is necessary materials. Next, we describe a simple circuit such manipulations.

The design of the jigsaw includes the following components: a handle, a switch button, an insulating washer, a power cord, a frame, a heating thread, a screw clamp and an earring. First you need to make a frame. You will need a duralumin pipe with an outer diameter of up to twelve millimeters.

You can also use textolite with a thickness of at least ten millimeters or thick plywood for the base. But keep in mind, the lighter the frame, the more convenient the jigsaw will be to use. Be sure to provide a channel so that you can later lay the power cord. most best form A frame is one whose side is bent 45 degrees.

Next, you need to make an earring. It is made of copper sheet with a thickness of one millimeter. After that, it is fastened with screws to the frame, where it connects to the handle. Thus, the screw, wing nut and earring will form a clamp in which the heating thread can be fixed. The thickness of the duralumin sheet should be up to 0.8 millimeters. It is necessary to make clamping cheeks from it, between which there is a button-switch.

After that, you need to cut a gap in the plywood through which the file can pass. It can be done with a drill. To do this, it is necessary to drill holes along the marking line, and smooth the transitions. Instead of plywood, you can use plastic, metal, plexiglass and others. Next, you place and drill mounting holes on the plywood and base plate jigsaw.

Then you need to fix the jigsaw with screws on the plywood base so that the file can pass through the gap. You attach the structure to the table with a clamp so that the file is pointing up. You can also secure the platform in any way you can.
The jigsaw file remains ordinary, but the possibilities for good sawing expand due to the release of hands.

You can use a nichrome coil from any household heating device (for example, an iron) as a heating filament. It must be secured with tension between the ends of the frame bends. To heat up the thread, you need to apply a tension of about 14 V. To control the operating mode, you can use a rheostat.

The current is determined by the thickness and length of the nichrome filament. With the help of a rheostat, it will be possible to set the optimal current strength (no more than 3-5 A), which will affect the temperature to which the thread is heated. Before starting work, it is necessary to determine the current strength. But keep in mind that if the force is too high, the material being cut out can be caught in flames, and if it is not enough, it will not be taken. A do-it-yourself desktop jigsaw will allow you to cut out figures with complex contours from different kind materials.

Rules for using a desktop jigsaw

When working with a desktop jigsaw, you must adhere to some rules:

1. While cutting, do not press hard on the tool, otherwise, at best, the needle will break, at worst, you will spoil the work.
2. Change blades from time to time. An old saw can spoil and destroy the surface of the material.
3. If you work with organic glass and non-ferrous alloys, the surface of the product must be moistened with water. Such an operation will speed up the process and extend the life of the saw.
4. If you are cutting a surface with a thickness of less than one millimeter, place a sheet of wood or plywood under the material being processed.
5. Before cutting, it is necessary to fix the material. It is better not to make long cuts by hand, the line may turn out to be crooked.
6. For cutting different materials appropriate blades are needed, with a special pitch and length.
7. Rotate the tool by turning only the back of the tool.
8. When cutting the laminate, an adhesive tape is glued to the cut line, which protects the material from chipping.
9. If the need arises for curved cuts, set the jigsaw pendulum to a minimum.

If you have not yet fully understood how to make a desktop electric jigsaw, watch a video about this procedure. This tool allows you to cut complex parts from wood and other materials, to make longitudinal, oblique, straight and transverse cuts. With the help of an electric jigsaw, you can process large parts, wide workpieces and small products, which is not superfluous at home.

Having made a jigsaw with your own hands, it will turn out not only to purchase practical tool but also save cash: it will be much cheaper than the factory counterpart, while having a full range of functions. A home-made electric jigsaw will allow you to create complex-shaped products from wood, plastic and other materials, the production of which with a hand tool under normal conditions would take a lot of time and effort.

A homemade jigsaw allows you to make cuts of complex shapes.

You should consider the structure and sequence of manufacturing a simple desktop electric jigsaw, assembly features and the procedure for working with it.

How is a desktop jigsaw arranged?

As the name implies, this tool is designed to be placed on the surface of a desktop or workbench. Compact dimensions allow you to work with a jigsaw both in the workshop or garage, and at home. The electric jigsaw is indispensable tool for the manufacture of complex decorations from wood, figurative carving on plywood and similar works.

Kinematic diagram of the jigsaw drive.

It is necessary to consider in more detail the structure of a factory-made desktop jigsaw. This will allow you to understand the main features of the device and apply them in a homemade model.

The components of an electric jigsaw can be divided into 3 parts:

• movable frame with a saw;
• fixed base;
• Electrical engine.

The principle of operation of the tool is as follows: an electric motor rotates a crank mechanism, which converts rotational movements into reciprocating ones. Movements are transmitted to a movable frame on which the saw is stretched.

A homemade device works using the same principle. To simplify the design, the movable frame can be replaced with a conventional manual jigsaw.

Details for an electric jigsaw

When assembling an electric jigsaw, it is important to find a suitable motor that will drive the working tool - the saw. For this purpose, a motor from a drill, blender, food processor or other equipment of the same type.

The jigsaw frame is best made from aluminum pipe.

The moving frame is made of metal profiles, wooden planks or slats made of durable plastic. It is most convenient to work with square-section aluminum tubes, as they are easy to process, light in weight and have a significant margin of safety.

To fix the jigsaw in the desired position, a reliable frame made of wood or metal should be made for it. The dimensions of the frame do not have much effect on the operation of the jigsaw. They depend only on which version of the tool you need - a compact desktop or full-size, installed on the floor.

The jigsaw table is made from a thick sheet of plywood, in which a small diameter hole is made where the file will move (Fig. 2).

Between the case and the table place a gasket made of elastic material - rubber or leather, which will dampen the vibration.

There is an easier way to make homemade jigsaw. It consists in the fact that a manual electric jigsaw is mounted in a vertical position in a table-stand, while its file is attached tightly to the movable guide rails - levers.

Assembling a desktop jigsaw

Construction homemade jigsaw begins with the assembly of the body, which can be made of plywood, chipboard or metal. The most simple model this tool can do without a case, but in this case, strong vibrations occur, which can significantly affect the convenience of work. In this case, two holes are made in the jigsaw - one for attaching the crank to the tool, the second for movable fixation of the jigsaw itself to the table. After starting the engine, the jigsaw begins to produce reciprocating movements that contribute to sawing the material.

Such a spring will provide the desired tension on the jigsaw saw.

A more elaborate model includes two separate strips, at the ends of which wing nuts are installed. From the opposite end, the bars are pulled together by a strong spring, which ensures a constant tension of the saw. Such a device works from a separate engine or, for example, from a drill.

A vertical bar runs inside the case, which is fixedly attached to its bottom or one of the walls. Two holes are made in it, the distance between which should be 2-3 cm less than the length of a standard file. Bolts or studs are threaded into the holes, on which straps are put on to hold the file.

The engine is built into the body and is attached to the lower bar by means of a disk with a connecting rod mechanism. A table with a hole for a saw acts as a housing cover.

The main drawback of a jigsaw with a separate engine lies in its most intricate part - the crank mechanism. The file with it makes not only vertical, but also inclined movements, which cannot but affect the accuracy of cutting. If you want to get an accurate tool, then it is better to replace the engine with an inexpensive factory-made manual electric jigsaw. It is fixed under the surface of the case and a file is threaded through the table, clamping it with one end in a jigsaw, and with the other in the upper bar of the structure. This design provides sufficient cutting accuracy, bringing this parameter closer to factory models.

Advantages of working with an electric jigsaw

The electric jigsaw allows you to make complex cuts very accurately.

Unlike hand tool, an electric jigsaw has clear advantages, including:

• higher speed of work;
• the ability to work with two hands, thereby increasing accuracy;
• security - with proper organization labor stationary tool is much safer because it can not escape from the hands.

Besides, independent production an electric jigsaw will save money, since factory machines of this type are quite expensive.

The era of the electric tool did not come with the first electric drills, but when the electric motor became an attribute of a tool of a narrower focus: scissors, hacksaws, a wrench and, of course, a jigsaw.

Moreover, the electric jigsaw was one of the first in this series. Today it is one of the most popular tools in the home (and not only) workshop. And first of all, we are talking about a hand tool.

But we are considering jigsaws in this article, and this is practically stationary devices, which often have their own specific place in the workshop, for for comfortable work they require a base with the given parameters: height so that the arm placed on the desktop has a bend at the elbow at 90º and stability so that it dampens the vibrations of the machine itself.

What are jigsaws for?

Jigsaw machines are primarily designed for sawing parts or elements of complex configuration in sheet material: wood, plywood, MDF, fiberboard, chipboard, plastic, aluminum. Also, with their help, the internal contours of products are cut out with preliminary drilling of the material being cut.

Such a tool, unlike manual or electric jigsaws, leaves both hands free for those working on it, which greatly facilitates the work and allows you to perform it with the greatest accuracy. Most jigsaws, provided correct selection and installation of nail files, allow cutting even in rather thick workpieces, with strict observance of an angle of 90º with respect to the plane of the workpiece.

Also, many models have an inclined table, which makes it possible to perform complex patterns at strictly specified angles other than straight, which is almost impossible when using manual or electric jigsaws.

Except home use, they are widely used in furniture production and manufacturing plants musical instruments. However, quite often they are replaced laser machines, but the burnt edges left by the latter do not make their use ubiquitous.

General drawing, structural features of desktop jigsaws

The most common layout for jigsaw machines is as follows:

It includes:

• a frame (or body) on which all components and mechanisms are attached;
• drive, often from the electric motor with a V-belt to the crank;
• a crank mechanism that converts the rotational movement of the motor shaft into the reciprocating movement of the file;
• double rocker with a tensioner and attachments for sawing;
• desktop, sometimes with a mechanism for turning in a horizontal plane at a given angle.

Previously, miniature jigsaws with a somewhat simplified design were on sale, but it was precisely because of it, which led to a quick failure of the saw blades due to their short stroke, that their production was discontinued.

Most of the currently produced desktop jigsaws work with files 200 - 350 mm long and have a working stroke of 30 to 50 mm.

The differences between the machines mainly consist in the power of the electric drive (from 90 to 500 W - for most models), as well as the type and methods of attaching saw blades. Optimal, in our opinion, is a power of 150 watts.

And files, in addition to length, can vary in width (from 2 to 10 mm), type of shank (with or without pins) and thickness (from 0.6 to 1.25 mm).

In some models, you can install the simplest, often called "Soviet", files for manual jigsaws, which is a big advantage. To implement just such an opportunity, owners of jigsaws that do not have it often improve the fastening of their devices by installing clamps from a manual jigsaw on them.

Most desktop jigsaws have 2 speed modes: more often - 600 and 1000 rpm, which is very useful when working with materials of different thickness, hardness and viscosity. The presence of the already mentioned turntable for 99% of the work performed on the machine - the function is useless.

Also, most jigsaws are equipped with additional devices, such as:

• compressor for blowing chips from the cutting line;
• sawing area illumination;
• drilling block, etc.

It’s impossible to call these devices useless, but it’s still not worth focusing on their presence when choosing a desktop jigsaw, since the same functions can be successfully performed:

• a compressor for an aquarium, with a blowing power chosen by you, is often more efficient than a regular one;
• a table lamp or a carrier with a luminous flux that is comfortable for your eyes;
• electric drill or screwdriver.

Even more complex devices, such as engraving drills that your machine can be equipped with, generally cause some bewilderment, but we’ll say right away that it’s better to have such tools that are not tied to a jigsaw (or any other) machine. Their mobility is often more expensive than the extended functionality of this very machine. Plus, it's not all free.

We make a choice of a manufacturer of a jigsaw machine

Most often, the Russian consumer has a choice of jigsaws Proxxon, Dewalt, Hegner, Xendoll, Bison, JET, Encore Corvette and Kroton. Each of them has its own advantages and disadvantages. We would, in terms of reliability and compliance with the characteristics declared by the manufacturer, single out the machines of the German company Hegner. Yes, and the line of this equipment they have is more authentic than many, but be sure to insist on sea trials when buying, regardless of which machine of which company you are going to buy.

And even if it is possible to choose from 2 identical machines, demand to turn on both. Buy one that has less noise and vibration.

Do-it-yourself jigsaw machine

Finding a drawing of such equipment on the Internet is a rather trivial task, but we do not consider it appropriate to single out any specific one, due to completely different approaches to implementation, both the very idea of ​​\u200b\u200bbuilding such a machine, and the selection of materials, type of drive and other things. We will offer several concepts for a homemade jigsaw machine and briefly analyze the advantages and disadvantages of each so that you can figure out what is best for you.

• First: the easiest to implement, suitable for most tasks for the manufacture of parts with a rather complex contour at home.

There are many options for attaching a manual electric jigsaw to a tabletop that serves as the desktop of the machine. Choose any, or offer your own and share with the readers of our site, for which we will be grateful.

The video also shows how to make a complex contour using not the thinnest file. And the main drawback of this design is the impossibility of using thin files, which makes it difficult to manufacture openwork details.

• Second: wooden. Interesting due to the fact that the material is available, easy to process and repair.

In our opinion, it is interesting to use the same manual electric jigsaw, which is rational for two reasons:

• if necessary, it can be used as independent tool, which was made;
• the drive has a built-in speed control, oscillation amplitude, eliminates additional mechanisms that reduce the reliability of the design.

However, for those who like to craft, there is alternatives manufacture of a wooden jigsaw.

When using a drill or a screwdriver with an adjustable output shaft speed as a drive, it will also be possible to smoothly adjust the frequency of the saw blade.

Moreover, the control of this process can be transferred to the pedal with the help of a simple device, which will make the work even more comfortable, and the cut more accurate. Such jigsaws must be well reinforced with braces and stringers and securely fastened to the floor so that they do not move during operation.

• Third: metal. There is no doubt that this concept is the most reliable and durable (provided that serious manufacturing errors are excluded), but also the most expensive. It makes sense to implement it if the work will be a large number of and you will be able to save a sufficient amount by using the materials you already have. Otherwise, there is not so much sense in making such structures with your own hands, given that inexpensive factory-made jigsaw machines can be purchased for less than 4 thousand rubles.

Of course, the latter does not matter if you are interested in the process of technical creativity itself.

Dear readers, if you still have questions, ask them using the form below. We will be glad to communicate with you;)

An electric jigsaw is a tool without which it is simply impossible to perform many woodworking and material processing works in which it is used. Possessing compactness and low weight, a manual portable jigsaw is able to cut out products of very complex geometry from a workpiece.

In work, the jigsaw is very convenient and besides, it provides very precise and thin cut. If you do not want to spend money on a purchased jigsaw, you can make it yourself 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 fabricated design is its simplicity. It can be easily mounted on a countertop or workbench and, if necessary, can also be easily disassembled. disadvantage homemade design can be considered as a 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 mm thick. In this case, in the sole of your power tool, you may also have to make holes for the mounting screws.

Homemade design can be attached to workbench with 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 during operation. Such a machine can easily handle the processing of small workpieces up to 30 millimeters thick. A drawing of this type of machine can be easily found on the Internet, and then with your own hands you can assemble it 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 machine cover.
4. Confirmants.

There is a second version of a stationary device for working with wood material, which is assembled from a larger number of spare parts, but it will not be difficult to make it. The bed is made of chipboard and consists of a rear wall and two sidewalls. To make it easy to get to the power button, the front wall of the machine is missing.

IN back wall do-it-yourself necessary drill holes for vacuum cleaner tube and cord. The cover for the machine can be made from laminated plywood 10 millimeters thick. The whole structure can be pulled together by confirmants. The jigsaw can be fixed in the same way as described above in the first case.

On a machine made according to this option, more massive workpieces can be processed, however, when working with a thick workpiece, the jigsaw saw can go in both directions and lean back. In this case, the accuracy of the cut deteriorates. This disadvantage can be easily eliminated with your own hands by installing a bracket on a home-made machine that will serve as an emphasis.

The jigsaw saw will move between two 11mm bearings, which must be screwed to the 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 a given path.

The bracket must be attached to the frame, made of bars 50 by 50 millimeters. 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 fixed tightly to the sidewall of the machine, but pressed against it with a hardboard, steel or textolite plate. Install vertical rack frame between hardboard and bed.

The machine can be more convenient if you mount an additional limiting 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 with clamps. His made from wood beam, aluminum or steel corner. You can also, for convenience, install a bar on a sled, which must be fixed to the sides or bottom of the tabletop.

Table for jigsaw machine made of chipboard

For making this jigsaw table you must have a certain carpentry skill, since when connecting its tsarg with legs, it must be made into a tenon groove. The tenon groove itself can be changed to a connection using dowels, wood glue and self-tapping screws.

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

The table is assembled from the following materials:

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

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

At each end of the prolegs and the tsarg, it is necessary to drill two holes for the dowels. The same holes must be made on the sidewalls of the legs. Coat the dowels with glue for half their length and insert into the ends. After that, assemble the frame completely. It will turn out to be indestructible. After checking and possible corrections, it tightens tightly.

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

The lid must be attached to one of the drawers with the help of hinges; for this, a slot must be made in it to facilitate the removal and installation of the jigsaw. In the countertop on the back side, it is necessary to screw two strips with a pre-selected quarter, into which the sole of the power tool should enter.

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

As a result, the table will turn out to be very simple and spacious, so the necessary strength of its cover can be provided by a large thickness of chipboard or plywood. Use sheets of 20 mm or thicker.

Jigsaw machine using thin saws

Since, when cutting difficult patterns in plywood, I saw an electric jigsaw, it is not well suited for this, you need to take a thin nail file. It can be attached to a hand-held power tool using the original fixture.

We also attach the jigsaw to the tabletop, but a thin file must be pulled, as it will not be enough just set on a pendulum. To facilitate the process of stretching the file, it is necessary to make a rocker from a bar.

In this case, the tension of your web is provided by means of a spring. Put its lower loop on the transverse hairpin. The upper loop must be inserted into the adjusting screw, which changes the tension of the damper. All wooden blanks for a homemade machine are made of hard rock tree.

Since the jigsaw machine does not have the possibility of attaching a thin-section blade, you can redo the chip old saw, after drilling a hole in it and completing 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 part. To make it easier for you, you can take an old jigsaw to make a trimming plate.
