Desktop jigsaw - equipment for cutting, sawing curly parts from various materials. Its feature is the possibility of cutting while maintaining the integrity of the outer contour of the workpiece. Depending on which file is installed on the structure, the machine can process natural wood, its derivatives, plastic bases or metal.

The device is indispensable for construction and repair work, the production of furniture, souvenirs. Often equipment is purchased for domestic purposes. Sometimes it is irrational to buy a factory unit: you can make a jigsaw yourself. The photo shows the design of the tool.

Device and principle of operation

The stationary factory sample includes a desktop for a jigsaw, a unit with a cutting element is fixed on it, an electric drive installed under the table top and a crank mechanism. The tension unit is installed at the top or bottom of the machine. Many models of units allow you to cut material at different angles. This is necessary for the implementation of an oblique cut. Often, for convenience, markings are applied to the swivel mechanism, stops, guides. The length of the cut depends on the dimensions of the table, in most models it is 30–40 cm.

The power of an electric jigsaw can be small. For domestic purposes, a 150 W unit is sufficient.

An important element is the crank mechanism. He is responsible for the quality of the transmission of the engine torque in the forward-return movement performed by the cutting element in a vertical position.

A standard jigsaw tool is characterized by an oscillation frequency of up to 1000 per minute with an amplitude of 3-5 cm. In some samples, the speed of processing various materials is adjusted. In most cases, a saw up to 35 cm long is installed on such a tool, which allows cutting parts up to 10 cm thick.

In order for the cutting element to serve for a long time without breakages, cracks, it is necessary to provide it with optimal tension along the entire length. For this, helical and spring springs are used. As an additional option on the factory machines, an air pump is provided to remove sawdust from the cutting line. A block with a drilling rig is useful, but you need to pay extra for each additional node.

Assembly instructions

A jigsaw is made from a refrigerator compressor, an ordinary drill. You can set the cutting blade in motion using the engine from the washing machine. Another option is to use manual electric jigsaws, old sewing machines. The figure shows a design drawing.

How to remake a manual jigsaw

First of all, the table is made. For this, a sheet of thick plywood or metal is used. Through holes are cut in it for the cutting blade, fasteners. Through them, the manual unit placed from below is fixed to the supporting structure. Next, the jigsaw table is fixed on any stable wooden table. Guide rails are added.

If necessary, the machine can be quickly disassembled.

The standard device is equipped with springs that provide the file with the required level of tension. You can not do without a rocker, one of its edges is under spring tension, the second provides attachment to the cutting element of the jigsaw. You can also clamp the web between two guide rollers.

Before starting work on a homemade jigsaw, the pendulum stroke must be turned off.

Machine from a sewing machine

A jigsaw from a sewing machine contains a saw blade travel controller provided with a speed switch on the equipment.

For manufacturing, the weaving mechanism is removed. In most designs, it is placed below. The bolts are unscrewed, the cotter pin is knocked out, the drive shaft leading to the thread weaving unit is removed.

Then the upper protective panel opens, the groove along which the needle moved expands to the file width parameters. Jigsaw saws are slightly modified: they are cut according to the size of the longest needle that could be installed on the machine. In order not to make an adapter for fixing the cutting element to the seat, grind off the upper incisors, make the lower part of the blade sharp. A cutter is installed in the needle holder. After that, they start cutting blanks.

A very nimble and compact enough tool, it can be incredibly useful for cutting straight and curly shapes. The appearance and functionality of the electric jigsaws sold is impressive, making you believe in the incredible complexity of the design of these devices. In fact, to recreate such a mechanism, it is enough to understand the principle of its operation, have instructions and a desire to do something with your own hands. It is not at all necessary to be an expert in technology with many years of experience (although this quality will not be superfluous). Next, we will conduct a detailed analysis of the average model of a jigsaw with drawings, and provide two detailed guides for the independent manufacture of such a tool.

How an electric jigsaw works

Although the jigsaw device is not particularly complex, its mechanism has certain features that require familiarization. To understand how to make a jigsaw, you must first understand what makes the saw blade reciprocate. For the most clear idea of ​​the principle of operation of the device, we will present the main components that make up the mechanism of the tool and describe their interaction with each other.

At the heart of any electric jigsaw are the following components: an electric motor, a gearbox and a rod with a saw blade clamp. Secondary but no less important elements include the start button, the support roller, the cooling fan and the soleplate. As additional functionality, many models have a pendulum stroke, a dust collector, a backlight and a laser guide. We will not touch on the principle of operation of the latter, and proceed to a description of the interaction of the main elements of the mechanism.

The high-frequency movements of the jigsaw saw blade originate from the electric motor, which is started by pressing a button or directly from the mains. The rotation is transmitted along the shaft to a special “reducer” mechanism with an eccentric, which interacts with the rod, forming reciprocating movements. In the mount, installed at the end of the rod, the saw is fixed, making the cut. To minimize the load on the rod with the gearbox, the rear edge of the saw blade rests against the support roller. Thus, all components of the device are involved in order to perform the main task of sawing all kinds of materials.

Drawings of electric balls

A detailed study of any device is much easier when there is a detailed diagram with a description of each element. Thanks to the exact names of parts with dimensions, the general idea of ​​​​the principle of operation of the mechanism becomes more visual. Below we have posted a few detailed illustrations, since it is much easier to assemble an electric jigsaw with detailed drawings than to rely only on your own idea of ​​​​the design features.

We hope that the presented diagrams will completely clarify your understanding of the structure of such a mechanism and provide useful food for thought in assembling your own jigsaw.

Making a jigsaw with your own hands

For a craftsman who understands the principle of operation of any mechanism, it will not be difficult to reproduce it, especially if there are detailed instructions on hand. The bicycle has already been invented, and to make it yourself, it is enough to have a set of necessary parts and tools available. The guide below will demonstrate in detail how to make a jigsaw with a complete listing of the elements and tools required for the job. The created product is not a stationary device, but a mobile saw with an electric drive. The power in the device is not so much, but enough to cut wood, up to 5 mm thick.

Required materials:

• Wooden block - 150x75x25 and 75x25x25 (width, height, thickness in mm)
• Metal plates - long and rectangular (as in the photo)
• Electric jigsaw file with U-shank
• Electric motor RS-540 12V (you can use any similar one)
• Electric circuit closing button
• gas stove nozzle
• Bicycle spoke
• Plastic circle with a diameter of 260 mm
• Plywood - 120x50x5
• Set of screws, bolts and nuts

By instruments:

• Hacksaw for metal
• triangular file
• Pliers (2 pcs)
• Screwdriver or drill with a set of drills
• Metal shears
• Pencil

When collecting materials, it is important to understand that the above components do not claim absolute accuracy and can be replaced with similar ones. When making a homemade jigsaw for sawing, you should focus on the presented manual, but do not forget about ingenuity and improvisation. If the specified element cannot be found, it can always be replaced with something.

The assembly of the jigsaw will begin with sawing out the handle from a larger bar. To do this, it is enough to cut, giving the rectangular board an L-shape, as in the photo. The dimensions of the sawn part are set "by eye", based on the preferences and size of the operator's hand.

One of the most important components of the device, serving as a movable rod and a saw blade retainer, requires increased reliability. This element is made of a long metal strip, 1 mm thick. At the end, the outline of the file shank is outlined, after which a triangular file is filed to create a pressure plate. Part of the metal strip is bent with pliers along the contour of the shank, after which a file is installed in an impromptu mount and a through hole is drilled for additional fixation with a bolt.

The saw blade, fixed on the rod, must be connected to the device using a guide. This part is made of rectangular metal plates. With the help of pliers, we bend the center of the plate into a flat groove for the stem with side mounting lugs. To prevent abrasion of wood and facilitate the movement of the file, we apply a similar piece of metal to the front side of the prepared handle and twist it together with the groove. As a result, the following construction should be obtained.

At the end of the rod, carefully bend the metal until a kind of loop is obtained, into which the end of the lever of the crank mechanism will be inserted.

We fasten the previously sawn off wooden rectangle to the top. It will serve as a stand for the motor, creating additional space for mounting the crank elements.

The transformation of engine rotations into reciprocating movements will occur with the help of an elementary mechanism made of a round plate, a gas nozzle and a weight-bearing spoke. In the center of the circle, we drill a hole with a diameter equal to the threaded part of the nozzle (so that it fits as tightly as possible). Next, install the nozzle in place and fix it with epoxy. We put the dried structure on the motor shaft. If the nozzle hole is too narrow, you can expand it with a drill of the required diameter. Between the center and the edge of the circle, we drill another small hole with the diameter of a bicycle spoke.

Unfortunately, not everywhere you can find an upgraded gas stove nozzle with a side screw used in the instructions. If only an ordinary one is available, it can be fixed on the shaft with a tin and a soldering iron, as in the photo below.

Having combined the engine with a round plate, it's time to turn it into a real crank. To do this, we take a bicycle knitting needle and bite off the bent hat and the threaded part with pliers to get an even metal rod. Next, we retreat from one end 10 mm, and bend at an angle of 90 °. We insert the bent part into the previously prepared eyelet in the stem and lift it up so that the screw for fixing the file rests against the metal plate.

The accuracy of the next step is most important, since the amplitude of the movement of the saw blade depends on it. It is necessary to determine the exact place for making the second bend of the rod so that the crank and rod connected by it work most efficiently. To do this, we put the engine in place of the future mounting and place the extreme hole of the circle up. Next, we bring a rod to the hole, the opposite edge of which is inserted into the eye of the rod raised to the stop and mark the place of the bend. We make a bend at an angle of 90 °, insert it into the hole of the circle and check the operation of the mechanism. If the crank works as it should, fix the motor in place with a metal plate.

The next structural element will be the sole, which also acts as a support for the saw blade. You can make a similar part from ordinary plywood, 5 mm thick. In the center of one of the ends, we make a small cut (20-30 mm) and pass the file of our jigsaw into it. We fix with a self-tapping screw with a countersunk head.

The final step is to install the start button and connect the wires. The button can be displayed in any place convenient for you. The author considered it necessary to put it on hot glue in the corner of the handle. We create an elementary electrical circuit (motor-button-network and motor-network) and connect it to a 12 volt power supply.

For smoother running, it is recommended to lubricate the stem with oil.

A more visual demonstration of this instruction, but unfortunately without comments, can be viewed in the video below.

Homemade jigsaw for polystyrene

Assembly of a fairly convenient and reliable device for cutting thin wooden blanks and polystyrene. This method is almost similar to the previous one, but has a more functional design. There is no need to compile a detailed description of how to make this electric jigsaw with your own hands, since the design of the device is similar to the previous assembly. We will give a complete list of the necessary materials and tools for manufacturing.

• Plywood 200x200x5 mm
• Wooden block - 120x50x50
• Spatula or sheet of metal, 1 mm thick
• Metal terminal for connecting wires
• Metal rod (spoke)
• Hacksaw blade
• Electric motor (DC) at 12 volts
• A piece of thin, flexible plastic
• Mounting metal corner
• A piece of PVC pipe as a handle
• Contact closure button
• 12 volt power supply with DC plug
• DC power connector
• Self-tapping screws, bolts and nuts

The above list of materials is only a subjective choice of the author of the instructions and does not claim to be absolute accuracy. When you do something with your own hands, you need to improvise and come up with non-standard applications for various parts. If you do not have any element available, perhaps another one can handle its function.

By instruments:

• File (file)
• Metal shears
• pliers
• Drill or screwdriver with a set of drill bits
• Core drill for wood with a diameter of 44 mm
• soldering iron
• Thermal gun

To more clearly understand the process of assembling all of the above elements, watch the detailed video “how to make a jigsaw with your own hands”. Most of the questions related to the design of the device will disappear by themselves.

Also, there is another option for making a homemade jigsaw. The principle of operation of this product is similar to the previous two, there are some nuances in the design. We hope that the following video will be useful and give you fresh ideas for creating your instrument.

In today's article, we will consider an extremely interesting homemade product that will surely come in handy for every homemade product. Namely, today we will look at how to make a jigsaw. This tool is very useful in the household and it very often comes in handy when building any homemade products. Today we will look at one of the cheapest and most affordable assembly options. Homemade will consist of the cheapest and most affordable materials that you probably have at home, and if not, then you can easily find them in your city, or you can order from our Chinese friends. In general, the homemade product is very interesting, so let's not delay with a long preface, let's go!

For this DIY we need:
- Collector electric motor 775 class. (these are usually put on professional RC models).
- Wires
- Some kind of plastic flywheel (large flat gear)
- PVC pipe, the inner diameter of which will be equal to the outer diameter of the electric motor
- Corner for PVC pipes
- Blade for electric jigsaw
- Small metal plate
- A small (but thick) board
- Thick wire (or for example a bicycle spoke)
- Button
- Power connector
- Power supply (12-24v 1-2A)
- Not a large sheet of laminated MDF panel or plywood

Of the tools we will also need:
- soldering iron
- Solder
- Marker
- Hot glue
- Wire cutters
- Pliers
- Round nose pliers
- Cold welding
- Self-tapping screws
- Screwdriver
- Shrink
- Drill and core drill (diameter equal to the diameter of the engine)

To begin with, we should choose the most important structural element, namely the electric motor. In our case, it should be with a large number of turns (such an engine has a large torque). And also in order for the homemade product to serve you for a long time, it should be noted that it is desirable that the motor shaft be on bearings, and not on bushings, as is often the case. We also need some kind of flywheel, the author of the homemade for this took a large and flat gear that he had.

We put our flywheel on the motor shaft, and since the diameter of the inner hole of the flywheel is slightly larger than the diameter of the motor shaft, the author of the homemade product decided to strengthen the connection with a small piece of cold welding. Such a connection turned out to be quite strong and reliable. Then, using a simple soldering iron, we solder two 15 cm wires to the contacts of the electric motor and insulate the connection with heat shrink.

After that, we need to take a PVC pipe, the inner diameter of which will be equal to the outer diameter of the electric motor. This pipe will serve as both a motor mount for our engine and a handle for our tool. We also need one suitable PVC corner for this pipe.

To begin with, we need to make all the necessary holes in PVC pipes. Namely, on a long pipe, we should make a hole for the button. To do this, leave a mark with a marker in a place convenient for you and make a through hole for installing the button. And on the corner, we should make a hole for installing the power connector (to make a hole, we repeat the same steps as we did with the pipe above).

Then we “press” the electric motor into the PVC pipe, which was prepared earlier. Note that the engine must be installed so that there is a minimum clearance between the PVC pipe and the flywheel (but the flywheel itself must not touch the pipe).

For the next step, we will need to take the jigsaw blade (which you plan to use) and a small metal plate. We apply the canvas to the metal plate, as shown below, and circle it around the office with a marker. Then, with the help of wire cutters, we cut out triangles from the metal plate so that, as a result, we have antennae in the place where the canvas expands.

We apply the canvas to the plate in the same way as we applied it earlier, and with the help of round-nose pliers we bend and press the antennae first, and then we bend the plate, as shown below. Next, with round-nose pliers, we twist the same “roll” as in the photo (see photo).

The next step we again need to take a small metal plate. We bend this plate with the help of pliers so that we get a “t” shaped part with a groove inside. Inside the groove itself, the canvas that we previously prepared should move quietly.

After that, we take a not large, but wide board with dimensions approximately as in the photo below. Then, in the indicated place (see photo), using a core drill, we make a through hole with such a diameter that a PVC pipe with an electric motor sits securely in it.

We apply another metal plate to the newly made workpiece in the place indicated in the photo. The metal plate should be slightly larger in width and length than the "T" shaped part that was made earlier. Then we attach the “T” shaped part to the plate, which is already on the board and, having drilled holes, fasten these plates to the board with self-tapping screws.

Then we need to take a thick and rigid metal wire or, for example, a bicycle spoke. And from this knitting needle we should make a kind of connecting rod (see photo). This part must connect the blade and the flywheel so that when the flywheel rotates, the blade moves "back and forth." You should end up with a piece similar to the one shown in the photo below.

After that, we install the “connecting rod” first on the canvas, and then install the PVC pipe with the electric motor in its place (to the board, as in the photo below). And the second horses of the "rod" into the flywheel hole. Rotating by hand, the flywheel checks the operability of the mechanism.

Let's move on to the electronic part of the homemade product. Namely, we set the button. We solder one wire from the electric motor to the button, and the second wire is just a segment of 5-6 cm. We insert the button into its mounting hole and fix it with hot glue. Then, after pushing the wires through the corner, we will install the corner itself on the plastic pipe, as shown below.

Then we need to install the power connector. We solder the wires coming from the electric motor and from the button to the connector itself (the wires should be pushed through the mounting hole for the connector), and finally, install and fix the power connector in its place with hot glue.

To the second end of the corner we insert a segment of the same PVC pipe. The length of the pipe should be such that when we put the structure on the table, the handle itself should be exactly parallel to the table. After that, we need to take some small sheet of laminated MDF panels or plywood, the main thing is that it slides well over the surface. From the panel you took, we cut out a similar blank, which is in the photo below and connect it to our mechanism with hot glue, and in the place where it connects to the tree, we fix it with self-tapping screws.

Everything is ready! As a result, we got a very useful tool that will definitely come in handy for you on the farm! It remains to connect the power supply and test, you can see the homemade test below.

A desktop jigsaw is an indispensable thing for any owner who is used to doing housework on his own. Especially electric jigsaws are good for residents of the private sector, lovers of manual labor and summer holidays. 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 a sewing machine with a 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.

Inside is an electric motor 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. Tools can be motorized, foot or hand-operated and are more productive. 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 plates, figures with a complex outline from laminate and drywall, plastic blanks, and 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 characteristics, type of power supply and design features. In hardware 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

The desktop electric jigsaw is a stationary design, so this type of cutting tool has many advantages. Modern models can work with wooden materials with a thickness of 40-50 millimeters. 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 customization options for the material and the required detail of the cut workpieces.

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 inconveniences are too large sizes and the difficulty of working with large details.

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 small piece of plywood and just an 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 you have the necessary materials. Next, we describe a simple scheme of 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. The best shape of the frame is the one with one of the sides deviated by 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 the base plate of the 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 conventional, but the possibilities for good sawing are expanded by freeing up the 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 various types of 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. To cut 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.

Making a smooth, straight cut with a budget jigsaw is not at all easy. The reasons are simple - backlash in the jigsaw, removal of the file, little experience of the master. All these reasons can be easily eliminated with a homemade bed with guides for the base of the jigsaw.

The presented design allows you to cut wood, sheet metal, plastic and even paper at an angle of 30, 45 or 90 degrees. Solely for the sake of experiment, I cut an old magazine and, as you can see in the photo, the cut turns out almost like from a printing house.

Required materials and tools:

• Sheet of fiberboard or plywood 400 x 700 mm;
• Reiki 30 x 50 and 20 x 30 mm;
• self-tapping screws;
• Studs M6;
• Wing nuts M6;
• Furniture fittings (screw nuts) M6;
• From tools: jigsaw, screwdriver / drill, square.

Step-by-step instructions for making guides for a jigsaw

1. As a basis for the village, I took a WPV door from an old closet. You can use a sheet of plywood. On the basis, we mark the centers of future supporting elements from wooden slats - the distance from the edge should be equal to half the thickness, in my case 15 mm with a slat thickness of 30 mm.

2. Along the perimeter, we make holes for self-tapping screws with a diameter of 3 mm with chamfers so that the heads of the self-tapping screws do not protrude above the plane of the bed base. 2-3 holes on each side.

3. The next step is to fasten the base supports from 30x50 mm rails with wood screws. Supports are necessary so that there is free space for a jigsaw file.

Finished back side.

And from the working side.

4. Next, we make guides from two 20x30 mm rails and a 10 mm plywood base, as well as jigsaw travel stops from a rail of the same section.

The length of the guides must correspond to the length of the frame, and the width is selected individually for each jigsaw. Looking ahead, I will present a photo from which the principle of selecting the width of the plywood base is clearly visible.

5. First you need to dismantle the base of the jigsaw. Next, applying a 20x30 mm rail, we make markings for fastening with self-tapping screws.

6. We place the rail under the plywood sheet, while the markings should remain on top!

We make three holes for self-tapping screws with chamfers to “hide” the fastener caps.

Fasten the rail to the base of the guide.
7. We fix the second side rail only after trying on the base - it should walk between the rails freely, but without backlash. After “trying on” the rail, we fasten it temporarily from above with two screws, and then, by analogy with the sixth step, we fix the second rail, and unscrew the temporary screws.

8. We fix the travel stops with two self-tapping screws.

9. According to the markup, in the first step we make marks with a pencil along the edges of the guide.

According to the marks, we mark and make holes with a diameter of 6 mm.

10. Using the holes made in the previous step as a conductor, we make holes in the base.

11. Using a 10 mm drill, we make blind holes 10 mm deep.

12. We screw furniture fittings into the holes obtained with a hexagon. They can be purchased at hardware stores for.

We screw the M6 ​​studs into the futorki.

13. We do similar operations on the guide.

Then we drill the internal thread of the futorka with a 6 mm drill.
14. We mount the guide on the studs.

The move should be free, without jamming.
15. According to the marking, we make a through hole for the jigsaw saw blade (do not forget to take into account the protruding pin).

16. We perform a longitudinal cut with a jigsaw, it is important not to rush at this step, cutting at a low speed with the pendulum mode turned off (mark "0") in order to get the most even cut without removing the file.

17. Using a square, perpendicular to the guide, we fix the stop from the rail 20x30 mm.
