How to make a homemade jigsaw machine. How to make a homemade desktop jigsaw How to make a jigsaw with your own hands at home

Here general scheme jigsaw machine operation.

I had a homemade machine, I already briefly wrote about it. Since I am a furniture maker, I made it from leftover LMDF. Cheap and cheerful :). I didn’t care at all about appearance, as long as I worked. And he did a good job! On it I understood all the nuances of sawing from solid wood hard rocks wood such as walnut, oak, ash. Everything would be fine, but the drive, and it was a Krees 350W construction jigsaw. I worked for 15 years! The speed control of the drive is “closed”, it turns on immediately to maximum and immediately breaks the file. I couldn’t find a native branded regulator. I have tried all kinds of regulators, dimmers for chandeliers and regulators from the seams. machines, vacuum cleaners. I could not achieve the desired result, namely a wide range of adjustment.

The photo shows the principle of operation of the jigsaw. construction jigsaw transfers oscillatory movements onto the rocker arm, on which the file is in turn attached.

In the end I gave up. The Moor has done his job, the Moor must go. I decided to buy a new jigsaw drive. All Chinese versions of jigsaws are not suitable; adjustment on them is the same name. In the Makita company store I found what I was looking for. 450 W jigsaw. Wide range of adjustment, and does not scream like Chinese jigsaws! It works quietly!

Here is my new drive, Makita 4327.

I found a new drive, but it didn’t work out to install it instead of the old one, the height is not suitable. I decided that rather than redo it, it would be better to make a new one, taking into account the elimination of the inconveniences identified during the process of working on the old one.

1. Increase the clearance from the file to the frame (on the old one it was 27 cm). For this you need an elongated rocker arm.

2. Increase the vertical stroke of the saw for good chip removal. (on the old one, the saw stroke is 18mm.)

3. Appearance! Schaub was not ashamed to take photographs. :)

And so! the machine is ready!

Here it is my new machine!

The clearance from the file to the frame is 45cm! The vertical stroke of the saw is 30mm! Dream!

Test cutting. The result is excellent! The Makita regulator works great. The machine makes noise like a household sewing machine.

Electric jigsaw machine– type of equipment for wood processing. Currently, the choice is presented not only in the usual manual version, but also in the electric version. These models, for example, Vario 502 dks, Dremel, have high performance, are quite easy to use, and come complete with a large number removable components.

These devices can be used both at home and in production. Today, such a mechanism can be bought ready-made or made with your own hands, for example, from an old sewing machine.

1 Technology of use

The main working element of a manual jigsaw is small files, which usually have a length of 50 to 120 mm. It is driven by an existing electric motor and makes translational movements vertically during processing of the product. In some mechanisms it works according to the pendulum type.

The workpiece itself in this design is attached directly to the base of the equipment. Such a fixation allows the worker to more easily operate the system and freely adjust the angle of the tool. Operator safety in this design is ensured by the presence of a special screen.

These models appeared on mass sale in recent years. Previously they tried to make them for home use from a sewing machine. Today there is no need for this. The choice of models is very large.

1.1 Advantages and disadvantages of using jigsaws

TO strengths It is this technique that must be attributed:

Possibility of using the device for a wide range of woodworking thanks to a large number replaceable cloths.
Greater reliability in use: due to the wide blade of such a mechanism, you can avoid breaking parts made of wood or tile during processing, as well as perform any complex contours with a minimum of effort.
The ability to feed a piece of wood with both hands by attaching it to the blade. Previously, without such a device, working with samples manual type was much more complex.
Ease of processing any kind of material – even relatively small ones the jigsaw can easily cope with wood 50 mm thick, not to mention more powerful models.
Wide range of processing options.

Among the disadvantages of using such a device, the short stroke of the samples is usually noted, due to which the work with thick webs is significantly more complicated.

It is also impossible to make the bending radius as small as when using a manual sample (due to the peculiarities of fastening the file).

2 Scope of application of machines

Modern electric jigsaw machines are suitable for next works to choose from:

Sawing complex contours from a sheet blank.
Processing the inner surface of the workpiece without violating its contour integrity.
Finishing of some samples.

A tabletop jigsaw machine is used primarily for processing wooden blanks. It is most often used in furniture production, musical instruments. In recent years, they have also often begun to be used for the production of decorative items, as well as souvenirs.

2.1 Consumables

The main consumables that it has table jigsaw, are files, including spiral ones. They differ in length, size of teeth, distance between them and are selected for each material individually.

Usually, when setting up a jigsaw machine with your own hands and buying files for it, experts recommend choosing consumables for the following features:

To cut wood or plywood workpieces, choose saw blades with a pitch of 2-4 mm.
Metal samples, as well as plastic, are usually processed by choosing 1-2 mm files, including spiral ones. Experts who provide reviews on the use of such components recommend choosing models with a wavy edge. The choice of these is very large.
When working with tiles, use special saw blades with an abrasive coating.

You can select these elements for processing wood and other materials not only based on reviews, but also based on technical characteristics the equipment you have chosen.

After all, almost every machine has a list of consumables, including all the files suitable for it for certain products.

Also, do not forget about additional elements such a design, which, for example, in the Dewalt, Dremel, Holzstar, Vario 502 dks models includes a drilling unit and an air pump. Their choice is great.

2.2 Design features of jigsaws

Currently, an electric jigsaw machine, in addition to those products that are created at home with your own hands, is presented on the market in a huge number various products. Their choice is really wide, including models Dewalt, Holzstar, Vario 502 dks.

They are classified according to the following features:

In order to choose the right jigsaw, you need to It is already possible to analyze the device according to all parameters. And then you can get the ideal component to perform any task. You can also assemble a tabletop jigsaw with your own hands using general recommendations for the production of such devices.

It will not be difficult to do this yourself using a sewing machine or other similar mechanism. The main thing is to study the design well, select the necessary components and do everything to make the model reliable.

2.3 Electric jigsaw machine Enkor Corvette-87 (video)

A tabletop jigsaw machine will be useful to every craftsman who cuts out thin parts. However, it is not always possible and meaningful to purchase a full-fledged machine. In that case, get down to business and make it yourself!

The structure of a jigsaw machine - what lies inside?

Jigsaw machines are more related to special tools than to devices that are needed as to an experienced master, and for the amateur who manages the garage. Their purpose comes down to a special task, namely cutting out complex curved contours from sheet materials. A special feature of such machines is the execution of cuts without violating the integrity of the external contour. Most often, sawing occurs on wood and derivative materials (plywood, chipboard, fiberboard), although modern machines equipped with appropriate saws can also work with other materials, for example, plastic or plasterboard.

Such equipment has found application in the music industry (making musical instruments) and, of course, in the furniture industry. Those who like to make things in their own workshop also buy such units. The structure of a traditional jigsaw machine, designed according to all the rules, looks like this: the working surface on which the saw is mounted hides a drive (electric motor) and a crank structure underneath. The tension mechanism can be located either below or above the machine.

To process a part, it must be placed on the workbench. Many models have the ability to rotate it at different angles to make bevel cuts. The stops and guides on the surface, as well as the rotating mechanism, can be marked, which greatly simplifies and speeds up the work. The length of the cut depends on the length of the work table - most models are limited to 30-40 cm. Electric motor power is an important, but still far from the most fundamental factor, since the machine has a huge reserve of unclaimed power. For example, for a home workshop or even small production An “engine” of only 150 W is enough.

The crank mechanism is much more important detail, because in this case the quality of transmission of the drive’s torque into the translational-reciprocal motion directed in the vertical plane by means of a saw depends on it.

Standard jigsaw machines are considered to be devices with an amplitude of movement of around 3-5 cm and a vibration frequency of up to 1000 per minute. Many models provide a change of speed mode for different materials. The jigsaw file itself is usually made up to 35 cm long and is capable of sawing material up to 10 cm thick. The width of the files can vary in a fairly wide range - from very thin two-millimeter to coarser ten-millimeter, with a thickness from 0.6 mm to 1.25 mm.

Even the thickest and widest file will easily break if you do not provide sufficient tension along the entire length of the file. Leaf and coil springs are used for this. Quite often, such machines are equipped with an air pump, which cleans the cut from sawdust by blowing it, as well as a drilling unit. The latter device is especially useful, because in this case the master does not need to be distracted by connecting an electric drill and drilling a hole - everything happens on the working plane of the machine. Of course, you have to pay for convenience!

How to make a jigsaw with your own hands from a manual jigsaw?

On the Internet you will find many different designs of homemade machines, but most of them boil down to repurposing into this device. By using your ingenuity and watching the video, you can easily make a homemade jigsaw from this tool. The jigsaw only needs a little modification. In fact, it plays the role of a machine drive and a crank mechanism, but the rest needs to be thought out and implemented.

Of course, manufacturers are trying to please consumers in this area as well, offering their own platform options for quick and convenient remodeling, however, in reality only you can make a device that suits your needs. So, the first step is to make a support table, for which they most often use sheet metal. You need to make a beveled oblong hole in it for the saw blade and holes for fasteners (countersunk screws are recommended), and attach the jigsaw to the bottom of the support table.

This structure can only be strengthened wooden table. You can go beyond this and install guide rails. The convenience of such a device lies in the fact that in addition to performing functions that are not entirely inherent to it, you can always disconnect the drive and with a slight movement of your hand turn it back into a manual jigsaw! If you constantly need this tool for work, it makes sense specifically for the machine - it will be cheaper than spending money on a real machine.

Advantages and disadvantages - we continue to modify!

But such a unit inherits not only the advantages of the tool, but also its disadvantages, in particular, the file is too wide for filigree work, which significantly limits the curvature of the lines. If there is a need for this, there will be a way out. So far, our machine differs from the classic jigsaw unit in the absence of springs that would ensure sufficient tension on the file. But it’s quite easy to build a simple rocker, which on one side will be under the tension of springs, and on the other, fixed to a nail file.

There is another option - to clamp the nail file between two guide rollers, but the first option is still more reliable. Don't forget to turn off the pendulum action on your jigsaw before you start using your homemade machine. There is another design - if your tool is powerful enough, then it can only serve as a drive in a structure of two rocker arms, between which a nail file is stretched. The movement is transmitted through a file attached to the lower rocker.

Machine from a sewing machine - giving a second life to old tools!

If you inherited a foot-operated or hand-held sewing machine from your grandmother or mother, consider yourself the owner of an excellent jigsaw machine! Of course, for this you need to “work a little magic” on the machine. First, remove the thread weaving device, which is usually located at the bottom of the machine. There is nothing complicated about it, just unscrew two bolts. Then we knock out the cotter pin and remove the drive shaft leading to the thread weaving mechanism.

Having unscrewed the top panel that protects the mechanisms, it is necessary to expand the slot in which the needle went. Be guided by the needs and width of the nail file that you will use in your work. Files for a jigsaw of this kind also need to be slightly modified, namely cut to maximum length needles that could be used on this machine. Having ground off the upper teeth and sharpened the lower part to the point, all you have to do is insert the saw into the needle holder and test your machine in action!

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

Design features

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

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

How to make a machine from a jigsaw?

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

First you need to make a table where a homemade jigsaw will be installed in the future. To do this, use any durable sheet material - thick plywood, metal and others.
Through holes are made in the table for the cutting blade and various fasteners.
The resulting jigsaw table is installed and securely fastened to a suitable wooden table.
The resulting table is equipped with guide rails.
Fixed at the bottom manual jigsaw, which allows you to replace the drive mechanism of the machine and many of its other structural elements.

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

How to make a more professional instrument?

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

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

How to make a machine from a sewing machine?

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

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

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

DIY jigsaw machine - drawings and video details

Since childhood, we have been familiar with the technology of sawing with a jigsaw. The principle is simple - a stationary part is placed on a stand with a technological cutout, the cut is made by moving the saw. The quality of work depends on the steadfastness of the hands and the skill of the worker.

In this article we will tell you how to make a jigsaw machine yourself. For those who don’t want to bother and are ready to buy a factory tool, a review article by Viktor Tagaev will be useful - 11 popular jigsaw machines

In this way, you can literally cut lace from thin wooden or plastic blanks. However, the process is labor-intensive and slow. Therefore, many craftsmen thought about small-scale mechanization.

A simple design from the last century

More in the magazine Young technician“Drawings were offered on how to make a jigsaw machine with your own hands. Moreover, the design does not involve an electric drive; the drive is powered by muscular force, like a knife sharpener.

The machine consists of main parts:

bed (A)
work table (B) with slot for canvas
lever system (B) for holding the saw blade
flywheel (G), which is the primary drive pulley
crank mechanism (D), combined with a secondary drive pulley, and driving the levers (B)
pedal assembly (E) with a crank mechanism driving the flywheel (D)
saw blade tensioner (W)

The master uses his foot to move the flywheel (D). Using a belt drive, the crank mechanism (D) connected to the lower arm (B) rotates. A file is stretched between the levers; the degree of tension is regulated by a lanyard (G).

With a well-balanced flywheel, sufficient smooth running of the saw blade is ensured, and such a homemade jigsaw machine allows you to massively cut out the same type of workpiece, saving time and effort. In those days, jigsaw files were produced in the form of a flat, unidirectional strip.

Therefore, to obtain patterns complex shape I had to rotate the workpiece around the canvas. The dimensions of the workpiece are limited by the length of the arms (B).

From a mechanical jigsaw to an electric one one step

The foot drive cannot provide real freedom of action and uniformity of the saw stroke. It makes more sense to adapt an electric motor for the crank mechanism. However, if you use a tabletop jigsaw occasionally, there is no point in making stationary structure with its own motor.

How to use cold welding, and what is this term?

You can use home power tools. For example, a screwdriver with a rotation speed controller.

The materials used are literally scraps of wood and old trash. The only critical part is the bed. It is better to make it from durable plywood thickness of at least 18 mm.

We make all connections using wood screws; the joints can be coated with PVA glue. From the same material we assemble a support pedestal for the lever rod. The design of the support should not have any play; the subsequent accuracy of the entire machine depends on its strength.

The lever structure is assembled from wooden blanks. Of course, ordinary pine bars will not work here. It is necessary to use oak or beech. Don't let the cost of such material scare you - legs from an old chair are perfectly used for levers. We cut out the straightest sections - and a durable lever mechanism is ready.

At the ends of the levers we make longitudinal cuts into which we install fastenings for saw blades for jigsaw machines. The mount itself is a metal plate 2-3 mm thick with holes. The upper hole is for fastening in the lever, the lower one is used to clamp the saw blade. For convenience, we use wing nuts.

The lower arm has a similar design in a mirrored design.

We install the lever system in the frame. We connect the rear parts of the levers with a screw tie (lanyard). With its help, the tension of the saw blade is adjusted.

IMPORTANT! Before assembling the lever mechanism, you need to decide on the size of the blades. The entire structure is calculated according to the length of the file. The levers should be as parallel to each other as possible.

For convenience, you can install a support spring. In addition to its main function, it will serve as a buffer, softening jerks during the reciprocating movement of the mechanism.

The crank mechanism is made of plywood 10-12 mm thick. To secure the axis of rotation, we use embedded bearings, which are seated in prepared holes in the racks.

A gas generator with automatic start during a power outage will keep your home cozy

The racks are connected to each other, forming a strong support for the flywheel. An ordinary bolt or stud is used as an axis. Strength class no less than 8.

We connect the flywheel to the lower arm using a connecting rod. It is made from the same plywood. To increase the length of the seat for the axle, glue the two halves together. The rods for connecting to the lever are metal.

We check the movement of the trapezoid - the levers should move freely, the tension of the blade does not change. The rotation axes can be lubricated with grease. After combining all axial connections, we perform final fastening of the structure.

The next stage is the manufacture of a desktop with a rotating mechanism. The rotary arc with a slot is cut out of plywood.

We install the table on the bed for tightening rotary mechanism we use a wing nut or make a convenient flywheel from wood. Rotating the table top will allow you to cut the floor at different angles.

Used as a drive electric screwdriver. The cartridge is connected to the flywheel axis, and we get a removable electric motor. You use the electrical appliance as usual, and when you need to start a homemade jigsaw, you connect a screwdriver to the flywheel axis.

We use a variable force clamp as a speed regulator.

This simple device is made from a screw tightening (from table lamp or clamp) and a durable strap.

No drawings are required for manufacturing; all structural elements are made “on site”. It is convenient to work with the machine, despite the simplicity of the design.

You can make a machine according to this drawing, it doesn’t change the essence. Everything has been checked and it will work.

A very instructive video by an English DIY master. A detailed story with drawings and a demonstration of how to make a jigsaw from plywood, and a screwdriver was used as a motor; a drill can also be used.

Stationary design for intensive use

1. The bed is cut from heavy Chipboard boards(can be used old furniture), a stand for a lever structure made of textolite or hardboard. The levers themselves are made of square steel pipe. It is not necessary to buy blanks; they can be found in your garage (shed) or at recycling collection points

Feather removal machines - what are they and how to make the device yourself

1. Fastening elements for the blade can be made independently or picked up from an old jigsaw (metal hacksaw). Use regular saw blades for a wood jigsaw. You can secure the clamps with screws, or using tin and a soldering iron.

1. It doesn't matter which device you take the drive from. The main thing is a working electric motor and a working gearbox. You don't need power, torque will be provided by gear ratios

The structure is assembled from standard gearbox elements. If necessary, the connecting rod fastening can be strengthened with an additional metal insert. All racks and fastening elements are made of metal. This way there will be less vibration and there will be no wear.

1. The material of the countertop does not matter, the main thing is rigidity and smoothness. It is necessary to provide for rotation around the longitudinal axis. Therefore, the working slot must be long

1. To keep your hands free while working, it is better to start the electric drive using a foot button or pedal. You can use an old sewing machine attachment or make a button yourself

1. In order to make a jigsaw more accurate, it is necessary to eliminate the backlash of the blade at the cutting point. To do this, install a roller guide

You can make it yourself, again from scrap materials.

The lever supporting the guide is made movable so that the device can be used only when necessary.

The tension of the web in this design is carried out by a spring. The lower lever provides reciprocating movement, and the upper one is needed only to support the saw blade

Bottom line: you can make a jigsaw yourself without large financial costs. The main thing is to decide on the tasks and choose the optimal design.

Alexander made a very interesting homemade jigsaw. Step by step description For an explanation of the dimensions of the parts, see this video.

Do-it-yourself jigsaw machine: photo and video

This article will discuss the design of a homemade machine made from a household jigsaw. Below will be given step by step instructions, photos, videos, as well as drawings and diagrams.

Introduction

There are a lot of design options - from the simplest, where the file simply sticks out from the tabletop, to quite complex structures with guides, the ability to cut at an angle, when it is possible to set the file not only 90 degrees to the base, but to change the angle (well, within reason, of course). There are devices (machines) for sawing, that is, making a straight and even cut.

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 application in every workshop.

Purpose

A homemade jigsaw machine is universal tool and is very popular, therefore it can be used both at home and in industrial enterprises - furniture workshops or carpentry workshops. At the same time, of course, you need to understand that the quality of work largely depends on the jigsaw and file itself, and the design only helps and expands the capabilities of the hand tool.

What are they used for? It is very convenient to make various parts from sheet material, well, as a rule, these are all kinds of wooden materials:

solid wood;
plywood;
various boards (fibreboard, chipboard, MDF, etc.);

plastics
thin (soft) sheet metal

A distinctive feature is the use in the design of a standard (household) jigsaw, which almost every craftsman has, as a saw blade mover. Through simple manipulations, it is secured with the saw facing upwards, so the master does not drive the saw with the tool, but moves the workpiece.

Advantages

The main advantage of such structures in comparison with hand tools, is convenience when processing materials. During the processing process, the master does not hold the tool itself (it is quite weighty), but the workpiece. This allows you to perform work with maximum precision. In addition, the presence of stops makes it possible to cut evenly, but this is expensive.

Basic design

As mentioned above, there are a large number of design options, however, it is necessary to highlight the most basic basic structural elements, namely:

desktop (bed);
drive – jigsaw;
a rocker for attaching the file and keeping it taut.

The machines differ in such parameters as power (determined by the power of a hand-held power tool), the working stroke of the saw, and the method of its fastening. Of course, an important role is played by overall dimensions products, including area work surface table, which allows for better processing of certain workpieces. All other parameters (operating modes, laser illumination, etc.) are determined by the characteristics of the hand tool itself.

Step-by-step instructions for making the machine

In this section we will analyze in detail each step of creating our future friend and irreplaceable assistant. The main stages of our work:

Preparatory stage;
Creation of blanks;
Assembly.

It is also necessary to note what tools and materials we will need.

Materials and structural elements:

plywood 10, mm. Below is a table with plywood parameters.
spring;
a pair of bearings;

Tool:

Sawing machine. This can be either a circular saw or a homemade sawing machine made from a jigsaw;
A grinder or grinder for processing workpieces, or alternatively, you can use a hand-held grinder mounted at an angle of 90°;
Drilling machine or drill with drill bits;
Jigsaw with files;
Construction vacuum cleaner.

as well as other tools.

For reference, table on plywood parameters:

Plywood thickness, mm	Layers of plywood, no less	Sanded plywood		Unsanded plywood
Plywood thickness, mm	Layers of plywood, no less	Maximum deviation, mm	Different thickness	Deviation, mm	Different thickness
3 mm	3	+0,3/-0,4	0,6	+0,4/-0,3	0,6
4 mm	3	+0,3/-0,5		+0,8/-0,4	1,0
6 mm	5	+0,4/-0,5		+0,9/-0,4
9 mm	7	+0,4/-0,6		+1,0/-0,5
12 mm	9	+0,5/-0,7		+1,1/-0,6
15 mm	11	+0,6/-0,8		+1,2/-0,7	1,5
18 mm	13	+0,7/-0,9		+1,3/-0,8
21 mm	15	+0,8/-1,0		+1,4/-0,9
24 mm	17	+0,9/-1,1		+1,5/-1,0
27 mm	19	+1,0/-1,2	1,0	+1,6/-1,1	2,0
30 mm	21	+1,1/-1,3	1,0	+1,7/-1,2	2,0

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 outlines 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

On at this stage 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 lid and a jigsaw seat;

The blanks are cut into circular saw or on a homemade one sawing machine from a jigsaw.

We process the workpieces on a grinder or grinding machine sawing defects:

burrs,
unevenness,
chips

We drill technological holes.

Tip: In order to avoid chipping the workpieces being drilled, you need to place a block (or any other base) underneath and press the workpieces tightly against each other when drilling, as shown in the photo. In this case there will be no chips.

We sharpen the grooves with a file.

We drill out the seats for the bearings feather drill or a Forstner drill.

We make the necessary technological grooves for the quick-release cover and for the jigsaw seat using a router.

Assembly

At this stage you need to do:

Assembling the main parts using glue;
Assembling the main parts with screws;
Grinding of workpieces;
Varnish coating;
SKD assembly;
Secure the base;
Secure the cover (frame);
Press in the bearings;
Install the bracket;
Install the spring;
Install the saw plate;
Making technological holes for jigsaw controls;
Manufacturing of fasteners for the saw (upper and lower);
Installation of a jigsaw and file;
Adjustment of the saw in two axes;
Fabrication and insertion of the plate;

We assemble the parts using glue and fix the parts with clamps.

Further fixation is carried out using screws and a screwdriver:

After assembling the parts, you need to grind them to correct irregularities and remove burrs so as not to injure your hands when operating the future machine.

We assemble the main structure using screws.

We fix the base.

We attach the lid (table top).

We press in the bearings. Pressing can be done either using a clamp or a vice, or you can simply hammer it in with a hammer.

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 hamper 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 outlet and a switch that would turn the voltage on and off in the outlet. 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 “BU”), and with an angle grinder (angle grinder) you saw off almost the entire cutting part and leave the shank. 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 table top of the machine.

We fix the file into the upper and lower clamps.

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.

Do-it-yourself desktop jigsaw machine

Cutting small pieces of wood is done with a jigsaw. The device is small in size and usually has an electric drive. Factory models differ in their characteristics and cost. For small volumes of wood processing, it makes sense to make a jigsaw machine yourself, using improvised materials. This requires a few factory parts.

A factory-made jigsaw is reliable device, the operation of which is guaranteed by the manufacturer. Manual models are low cost. Stationary devices are expensive, but provide proper comfort when processing wood. The set of components in the device is largely the same for everyone.

The design consists of the following parts:

The part to be processed is placed on the work table. The size of the workpiece depends on its dimensions. Some models have turntable, which makes working with the part easier - visibility improves. The presence of graduations makes it easier to mark the material.

Average characteristics of factory machines:

Models for specialized purposes may have radically different characteristics. There are no specifications large sizes, for processing small parts. As well as models of large sizes, the industry also produces them for retail sale. But such options will be very expensive.

Features of extracting a drill for a hammer drill

In the middle class there is high competition for consumers, so the devices will be cheaper. The characteristics are also tailored to typical tasks carpenter Based on them, you need to make drawings of a jigsaw machine with your own hands. Complex components for it are purchased in the store.

Experts classify jigsaws by type of design. The design features of the mechanism determine the processing capabilities of wooden products.

The classification is carried out depending on the design of the jigsaws.

Device types:

With lower support.
Double-support.
On a pendant.
With degree scale and stop.
Universal.

Models with a lower support have become most widespread. The frame of the desktop factory device has 2 halves - lower and upper. The sawing and chip cleaning model is located on the top of the bed.

The lower frame contains a controller, an electric motor, a final drive, and an on/off button. This machine allows you to work with any materials and any size.

The presence of two supports in a jigsaw is advantageous in that the upper half of the bed has an additional rail. This jigsaw is ideal for cutting small parts. The thickness of the workpieces on both models should not exceed 8 cm. The worktable of such machines, as a rule, can be adjusted in height and angle of inclination.

Suspended devices do not have a fixed frame, but are distinguished by their mobility. The material being processed is set motionless, and the master moves the working module. since the latter is attached to the ceiling, the thickness of the material is not limited. The tool is moved manually, regardless of the bed. This allows you to make patterns of complex shapes.

The presence of a scale of degrees and stops is suitable for those craftsmen who carry out processing according to the drawings. Marking allows you to avoid errors when working. There are universal models of machines on the market that allow you to perform several operations. This machine allows you to perform drilling, cutting, polishing and grinding. The cost of such devices will be much higher, but working with them will be more comfortable. These are industrial specimens.

Designs and drawings of options presented on the network homemade jigsaw are different. This is due to the imagination of the authors and the desire to make a device that will stand out from the rest. Only the concept in most cases is the same - they take a manual jigsaw as a basis and repurpose it.

How to choose a circular saw blade

Home woodworking enthusiasts often look for information on how to make a jigsaw with their own hands without any special skills. You can use a ready-made manual jigsaw as a base. The mechanism does not require careful modification. The factory manual device is a drive. But the crank mechanism will have to be developed independently. Manufacturers are trying to offer consumers platforms for quick remodeling, but personal needs can only be satisfied with their product.

Assembly order:

A support table is made. A sheet of metal is taken as a material and a hole is made in it. The shape is oblong, 3-4 times wider than the saw blade. Holes for fasteners are made nearby.
The factory device is fixed at the bottom of the support table. Holes for fasteners are made next to the hole for the saw blade. Countersunk head screws are used as fasteners. This is necessary in order to ensure a perfectly flat plane of the table. Otherwise, the processed products will cling to the caps of the wines, which will cause inconvenience in work.
The structure is fixed on a wooden table.

The advantage of creating a jigsaw machine with your own hands is that the factory tool can be disconnected at any time. When necessary, you have an ordinary manual jigsaw in your hands. Therefore it is better to purchase manual option a tool that can be used on a homemade machine - it’s cheaper. Stationary devices are expensive.

Comfortable work with wooden products can be achieved by installing guide rails on a homemade support table. Additionally, markings are applied to the table, which makes it easier to measure distances on parts during processing.

A manual jigsaw as the main device for a machine has disadvantages. Main problem lies in the file - it is too wide in manual models. Because of this delicate work It is difficult to do on wood with it - the curvature of the lines is limited.

The previous design is simple and does not have additional parts that make working with wood easier. The direction of modernization is the possibility of replacing the file with a thin one.

Options for improving the design:

Build a rocker. The structure will be tensioned by springs on one side. The second side of the rocker is fixed to the file.
Secure the file between two rollers. They serve as guides for the thin file.
A stationary factory device is used as a drive for a system of two rocker arms. A file is pulled between the latter. The movement is transmitted from the factory device to the lower beam of the saw.

The principle of operation of a caliper, types of tools and examples of measurements

Design upon purchase or self-production you have to choose based on personal preferences and desire to tinker with technology. Using guide rollers is a less popular option - its reliability is poor.

Modernization by installing rocker arms is common. It is better that the factory device only serves as a drive for the jigsaw file. To do this, you need to turn off the pendulum stroke in the tool.

The heir to a grandparent's estate often gets an old sewing machine. It has already served its purpose for sewing clothes, since more precise equipment is now being produced. If you don’t have a jigsaw on your household, you don’t have to spend money on buying one. It is made with your own hands from a sewing machine.

Procedure:

Now the jigsaw for figured sawing ready for plywood. WITH manual drive It will be more difficult to work because your legs will get tired. An additional disadvantage will be vibrations from force on the tool. The electric drive of the machine, converted into a jigsaw, partially solves the problem of vibrations.

An expensive jigsaw can be replaced with a homemade design. It will not be inferior in quality and functionality if you approach the assembly process responsibly. It is important to make high-quality plywood mechanisms that serve as a support table. It is desirable that the table be able to rotate. For option with sewing machine it will be impossible to do this. If desired, markings are applied to the table to make it easier to measure parts during work.
