Pavel Ivanov will tell us about his homemade product - a jigsaw installed in a table. Here he is . The entire structure is made from scraps of 16 mm chipboard. Frame parts (support arm - made of wooden blocks and pieces of plywood/MDF). Table width 250 mm
The jigsaw is secured to the base with a pair of bolts screwed into the base at the front and a bolt at the back. The bolt heads are recessed into the base so that the parts being cut do not catch.
The saw stop is made from a zero bar (sold in electrical stores), a piece of steel wire, and a couple of corners. In addition, a spare jigsaw roller was installed (included in the kit). It is advisable to use a longer file.
Close attention should be paid to the roller and especially to the accuracy of its alignment relative to the file. Under no circumstances should it touch the file; there should be a small gap left, otherwise there will be a lot of noise during operation, heating of the rubbing unit and vibration. First, it is advisable to assemble the shoulder-rest separately, put it in place (glue + 3 long confirmations, install a jigsaw with a file, and only then screw the assembled assembly with the roller.
The support arm was additionally reinforced with plywood triangles (strong vibration).
The stage (this is the orange part) moves back and forth within the groove. During the “combat” tests, I sawed long (1.5 m) boards, so I simply “screwed” the orange board to the base. 
Advantages compared to a simple jigsaw: both hands are free for work, it cuts fairly evenly - there is no saw blade moving to the sides. It is possible to connect a vacuum cleaner to the standard connector of the jigsaw.
The disadvantages include weight and size. Still, the thing is stationary.
Using desktop jigsaw machine at home you can make furniture, beautiful patterned shelves and much more. The mechanism allows you to cut smooth and curved parts from wood, plastic and dense foam materials. In order for a homemade device to fully satisfy the requirements, it is necessary to carefully select a suitable design.
Design and technical characteristics
The device of any model of jigsaw machine necessarily contains:
- saw;
- crank assembly;
- drive unit;
- saw tension device;
- Desktop;
- auxiliary mechanisms.
The material to be processed is placed on the work table. Some models are equipped rotating device, changing the slope of the surface. To make it easier to mark the material with your own hands, graduations are applied to the surface.
How larger size table, the longer the cut can be made. On average, this figure is 30 - 40 cm.
Drive power for homemade desktop machine is about 150 W.
The crank assembly converts the rotational motion of the drive into reciprocating motion and transmits it to the saw. On average, the frequency of saw blade vibrations per minute is 800 - 1000. The amplitude of vertical movement is no more than 5 cm. Some models allow you to select the speed of movement depending on the properties of the material.
File hand jigsaw can work with wood, plastic with a thickness of no more than 10 cm, having a length of up to 35 cm. For different types The materials and work of the files vary, their width is 2 - 10 mm.
A manual tension device secures the saw blade for uniform sawing; it consists of screw or leaf springs.
Types of machines
Structurally, all jigsaw devices can be divided:
- with lower support;
- with double support;
- on suspension;
- with degree scale and stops;
- universal.
The most common are models with a lower support. Their frame is divided into two halves: lower and upper. The cutting and cleaning module is located at the top. At the bottom there is a control module, an electric motor, a transmission mechanism and a switch. Allows you to process sheets of material of any size.
Models with double support differ in that there is an additional rail on the upper half of the bed. Such devices are good for creating oversized parts. They are easier to install than the previous option. Both models allow you to process material no thicker than 8 cm. The machine comes with a work table with angle and height adjustment.
Suspended machines are not equipped with a monolithic frame; they are very mobile. During processing, it is the cutting module that moves, not the material. The working module is usually attached to the ceiling with your own hands, so the size of the material is unlimited. Cutting tool moves by hand independently of the bed, creating very complex patterns.
Machines with a degree scale and stops are good for precision work according to drawings. The design allows you to avoid errors. Universal jigsaw machines can perform several operations associated with cutting: drilling, polishing, grinding.
Making a machine yourself
Drawing of a homemade tabletop jigsaw: 1 - rocking insert (2 pcs.), 2 - earring (2 pcs), 3 - table, 4.6 - screws, 5 - rod, 7 - eccentric, 8 - base, 9 - axes of earrings, 10 - upper rocker arm, 11 - rocker arm axis, 12 - wing, 13 - tension screw cross member (2 pcs), 14 - tension screw, 15 - rocker stand, 16 - lower rocker arm, 17 - box, 18 - double-ribbed pulley, 19 - intermediate shaft, 20 — stand bushing, 21 — table plate, 22 — bearing with cover (2 pcs.), 23 — electric motor pulley.
In the drawing of a tabletop machine made by yourself, the number of components must be kept to a minimum, these are: a rocking chair with a fixed saw, a bed and an electric motor. You can take a motor from an old electric machine.
Owners of a manual jigsaw are luckier. You can make a stand from a sheet of plywood and attach a jigsaw to it. To attach the jigsaw with your own hands, you will have to make holes in the base of the tool. The most simple model ready.
Now about the more complex and functional ones. The stand is made by hand from 12 mm plywood, thick plastic or textolite. It consists of a base, a box for housing the engine and mechanisms, and a work table. On the other side we place a rocking chair with an eccentric. They connect with each other metal plate with bushing bearings. The entire structure is secured with screws. To mount the intermediate shaft, prepare a pair of bearings. A double-strand metal pulley is placed on the shaft as tightly as possible, and the screw connection is secured. You can make an eccentric in the same way.
To change the amplitude of movement of the rocker, four round circles are made on the eccentric flange through holes with threads, located at different distances from the axis. By changing the installation location of the screw, the range of movement of the rocking chair is adjusted. It consists of a pair of wooden rocker arms hinged to a stand. The rear ends of the rocker arms contain through cuts; tension screws are inserted into them. A file is attached to the ends at the front and is movable due to metal hinges. Before fastening, the file is inserted into the groove work surface table.
The mechanism for attaching the file is very important. During production homemade device with his own hands he should be given Special attention. The inserted plates of the rocker arms bear constant loads when moving, so they are rigidly fixed and tightened with Grover screws and washers. The fastening earrings should not be strongly compressed by the screws, allowing the hinge axis of the plate to move.
Any man can make a jigsaw table with his own hands, even without special carpentry skills. Since a mains-powered jigsaw is an integral part of any household, it will require working space. Such a device significantly speeds up the work time, and also allows it to be carried out efficiently, clearly and quickly.
However, we should not forget that to achieve the most highest quality only possible through correct use this tool, that is, by placing it on a jigsaw table.
A stationary device will allow you to turn your tool into a mini-machine, thanks to which you can make a wide variety of patterns.
Jigsaw
A DIY electric jigsaw table has many advantages. In particular, that pick up everything necessary tools for this product it is possible without problems. Important condition— surface rigidity and evenness. Therefore, it is best to opt for a material such as plywood. But the boards should not be thin, as they may warp. Therefore, it is best to take waterproof laminated plywood about 1 cm thick.
Workbench-drawing Box for jigsaw
You can take particle board, which is somewhat thicker than plywood and also stiffer. But most suitable option there will be a high-quality laminate-covered kitchen countertop. The only disadvantage of this material is the poor attachment of tools to the material, so you will have to carefully select fasteners. Main advantage particle board is availability - place an order for everything necessary elements You can do it in any workshop. In this case, choose a thickness of about two cm.
Table for a jigsaw (dimensions) Place the jigsaw on a tabletop made of 12 mm laminated plywood and screw a chipboard base to it. Attach the base flush with the left edge of the tabletop. Make small indentations on other sides to strengthen the equipment
We make a couple of holes on the bracket for the bearings. We bolt the L-shaped structure to the base of the table with a piece of thick hardboard. Durable L-shaped structure, rear view
Workflow Now the jigsaw blade does not bend, even when cutting parts from a thick sheet of wood
A DIY metal table is an alternative to wood. The only difficulty is finding the right one metal part somewhat difficult - it must not only be smooth, but also carefully processed. In addition, it will be difficult to make holes for fastenings in such a part. If you watch the video and arm yourself with a drill, everything will be much easier.
At the same time, you should stock up on a simple pencil (it’s better to take a soft one so that it is brighter), a ruler or tape measure, a screwdriver, a drill, and self-tapping screws. In addition to this, we will need a square, with which we will mark the product, and also use it on last stage assemblies. At the last stage, fiolent tape and bearings will not be superfluous.
How the process works
In order to construct a basic table, you must prepare drawings. A correctly drawn or selected diagram will make your work much easier. Use plywood board up to one cm wide as a workplace. If the elements are small, you can take a smaller board. At the same time, step back from the edges up to twenty cm and make several holes. Don't forget to mark the places for fastenings at the bottom of the board.
If the jigsaw stand does not have holes, they must be made in four copies. Using the prepared marks, make holes in the plywood. Please note that steel legs must be attached to the board. In this case, the height of the legs depends on the body of the device itself. In this case, the planks are bent at an angle of 90 degrees. To do this, holes are made for fasteners. The device is secured under the plywood element so that the saw looks out through the hole.
Such an ordinary table can be installed on the same workbench or desktop. At the same time, such a table does not need legs, but is fixed at the edges of the workbench. The device should be outside the table. This product attaches perfectly to wood pieces up to three cm thick.
As you can see, making such a table for a jigsaw is not at all difficult. All you need is a little attention and concentration. And, of course, do not forget to strictly adhere to the scheme.
How to make a jigsaw table
If you want to make a table for regular jigsaw, the process will be much easier, since you will not need to bother preparing your workplace for power from the network. First, cut out a blank for the tabletop from plywood.
Don't forget to prepare the holes with a drill into which the screws will be screwed.
In the corners of the future structure there will be squares of plywood, which will add rigidity. Prepare the holes so that the jigsaw fits freely into them. The tabletop is attached using self-tapping screws. Don't forget to cut holes for the cutlery in the top of the future table. Please note that the tabletop is fixed rip fence, for this, self-tapping screws are driven into the holes. That's all. The most primitive table for a jigsaw is ready.
It’s even easier to make a sawing table:
Diagram of a sawing table Drawing of a sawing table Another design of a sawing table
Drawing of a classic sawing table It is made from two blanks. The blanks are connected to each other with screws. The screws must be recessed into the workpiece material so that they do not interfere with work
The jigsaw is convenient and useful tool on the farm. Electric jigsaw greatly speeds up the work and expands the possibilities of using such a tool. But real quality can only be achieved by installing a stationary device - a jigsaw table.
Having transformed hand tool V small machine, you can create original creations from the most different materials. This table allows you to make the most complex patterns and ornaments. The device will undoubtedly appeal to lovers of high-quality manual labor.
Features of an electric jigsaw
A jigsaw is a type of reciprocating saw cutting element(blades), in which the rotational movement of the electric motor is converted into translational movement of the saw in the form of oscillatory movements with a frequency of up to 50 cycles per second. This jigsaw makes it possible to make cuts inside a flat sheet in any direction, incl. with a rotation in an arc with a diameter of at least 3 cm. It can be used to cut many materials: chipboard, wood (up to 70 mm thick), a metal sheet(steel - up to 3 mm, copper, aluminum - up to 20 mm), tiles, plastic, natural and artificial stone.
Sawing the material is done by moving the saw upward. In addition, the file is provided with transverse vibration due to the presence of a pendulum mechanism. This improves the quality of straight lines when sawing. The tool provides adjustment of the speed of movement of the nail file, which is important when cutting different materials.
So, when sawing in a tree, you can set the maximum high speed; when working with plastic or aluminum, use the medium speed range; For steel and tiles, the speed must be reduced to a minimum. A special mechanism allows for cutting when inserting the file at an angle.
The file is secured in the jigsaw with its shank, in which a slot is made ( the best option- cross shape). The shank is secured in the block using two screws. The design of the clamping pads (chucks) may be different for different jigsaws. The files themselves have different shapes teeth for different materials.

Features of a table jigsaw
The use of a manual jigsaw implies that the workpiece is permanently fixed, and sawing is carried out by manually moving the jigsaw. The quality of the cut in this case depends entirely on the “steadiness of the hand” and the skills of the master: the accuracy of the line, the angle of insertion of the file, etc. A tabletop jigsaw changes the picture of the process: an electric jigsaw is fixed stationary in a vertical position at the bottom of the table, and the workpiece moves along the table surface only guided by hands.
In this case, firstly, the sawing process is physically facilitated; secondly, the quality of the cut is improved due to the strict verticality of the file and the accuracy of the workpiece movement when using guides. In addition, positioning the saw blade in an upward direction reduces the risk of surface chipping at the edges of the cut. The file has stable movement due to the use of mechanisms that ensure its tension and precise orientation. The jigsaw is securely mounted on a fairly massive and durable frame, which eliminates unwanted vibrations and movements of the tool.
In general table jigsaw is a stationary machine. Its design includes a table with an electric jigsaw mounted on it, as well as a system for guiding and tensioning the saw and a system for fastening and guiding the workpiece. The simplicity of the design allows you to make a table with your own hands. The size of the table is selected based on the size of the workpieces and parts being processed. To install sheets of significant size (for example, chipboard), additional extension systems may be provided.

The simplest design
You can make a simple table with your own hands very quickly. Used as a working surface plywood sheet thickness of at least 10 mm and size depending on the size of the workpiece being processed. For small workpieces, it is enough to take a sheet measuring 50x50 cm. In the central part, stepping back approximately 20-25 cm from the edge of the sheet, drill a hole with a diameter of 20-30 mm for a jigsaw file. At the bottom of the sheet, using the hole as a center, mark the fastening of the jigsaw sole. If there are no holes on the jigsaw sole, they must be drilled on drilling machine in the amount of 4 pieces and cut the M8-M10 thread. Four holes are drilled in the plywood sheet according to the marks.
Legs made of steel strips 3-4 mm thick and 30-40 mm wide are attached to the corners of the sheet. The height of the legs is determined by the size of the jigsaw body (to the sole) with an addition of 2-3 cm. The legs at the bottom need to be bent outward at a right angle and 1-2 holes with a diameter of 6-8 mm drilled into them for fastening. An electric jigsaw is attached to the bottom of a sheet of plywood so that the file comes out through the hole. Manufactured simple table with your own hands, which can be attached to any surface (workbench, table, etc.) and work.
An even simpler design does not include legs, but is attached to the edge of the workbench with clamps (two on each side for strength). The jigsaw should be outside the workbench. Such a table with your own hands can easily cope with wooden blanks up to 3 cm thick.

Slight design complication
You can do a little more complex table with your own hands. To do this, a frame is made from three chipboard panels 12-15 mm thick (two side panels measuring 50x80 cm and a back panel measuring 70x80 cm). The structure is assembled using wooden block or furniture corners. At the bottom, it is advisable to make a reinforcing lintel from a wooden block. The front of the frame does not close to provide access to the start button.
The top panel is made of a sheet of plywood with a thickness of 10-12 mm and a size of 70x100 cm and is equipped with a jigsaw in the same way simplest design. To eliminate saw blade vibration during cutting, it is provided simplest system stabilization. The file is passed between two bearings with a diameter of 10-12 mm. The bearings are mounted on a bracket made of steel strip, which, in turn, is fixed to the tabletop. On the tabletop you can install guides and limiting slats made of wooden blocks or aluminum profile. It is better to fasten them to the edges of the tabletop with clamps, which will make it possible to move them along the table. For precise movement, you can attach a tape measure to the ends of the tabletop.

Table based on bars
A more complex design involves making a table from wooden beams. In this case, the table is assembled from timber (legs from timber 80x80 mm, lintels from timber 40x80 mm) with a joint using the tongue-and-groove system.
To strengthen the structure, you need to use wood glue, dowels and screws. The distance between the legs is 60-70 cm. The legs are strengthened with collets. At the junction of the beams and collets, holes are drilled and dowels are secured. The height of the table is set by the manufacturer based on the ease of maintenance of the machine.
The tabletop is made of laminated plywood 18-20 mm thick, size 90x90 cm. For ease of changing saw blades, the tabletop is made in a lifting version. To do this, it is attached to one of the table collets using hinges. It is more convenient to remove the file if there is a cut from the hole to the edge of the tabletop. It is recommended to make such a cut.
The jigsaw mounting system should be complicated to ensure its removal. The sole of the jigsaw is pressed against the tabletop with two wooden planks, on which a profile is made by sampling a quarter of the timber. The jigsaw sole fits into this profile, like a runner. To fasten it, holes are drilled in the bar and clamping screws with a wing are installed.
This article will discuss the design homemade machine from a household jigsaw. Below will be given step-by-step instruction, photos, videos, as well as drawings and diagrams.
Introduction
There are a lot of design options - from the simplest, where it just sticks out from the tabletop, to quite complex structures with guides, the ability to cut at an angle, when it is possible to set not only 90 degrees to the base, but also change the angle (well, within reason, of course). There are devices (machines) for, that is, making straight and even cuts.
Such devices are increasingly used due to their versatility and functionality. In fact, their parameters and purpose are similar to stationary machines and have a strictly defined practical use in every workshop.

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