Homemade device for sawing wood. How to make a jigsaw from improvised means

The desktop jigsaw is designed for cutting various parts with a complex configuration from sheet materials. This tool is able to work with MDF, chipboard, fiberboard and many others. Also, jigsaws can cut out the internal contours of parts, if you first make a small hole. This tool has a wide range of applications, since it is able to provide high productivity, which cannot be achieved with a conventional hacksaw.

Design features

The device diagrams of all jigsaw machines are usually the same. Having carefully examined the drawings, which depict this tool, you can see its following structural units:

• 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 movement of the file used during operation;
• double rocker. Equipped with fasteners for sawing and tensioning device;
• Desktop. In some modern models, it has a turning mechanism that moves to a given angle.

How to make a machine from a jigsaw?

To make a jigsaw from a manual jigsaw, follow these instructions:

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

Everyone can make such a jigsaw machine with their own hands. Its advantage lies in the fact that at any time this unit can be quickly disassembled and only hand tools can be used.

How to make a more professional tool?

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

1. The bed is made of any durable material - 12 mm plywood, plastic, textolite and others. It should consist of a base, a body to accommodate all structural units and a desktop.
2. On the other hand, a rocking chair with an eccentric is placed. They need to be interconnected using metal plates with sleeve-type bearings. The resulting structure is installed with screws.
3. The intermediate shaft is formed from several bearings.
4. The metal pulley is very tightly put on the shaft and the screw connection is fixed.
5. To change the movement characteristics of the rocking chair, 4 round threaded holes are made on the eccentric flange. They should be placed from the center line at different distances. The amplitude of the movement of the rocking chair is regulated by the location of the screws.
6. The rocking chair is formed from wooden yokes, which are attached on a swivel joint to the rack.
7. Small cuts are made at the rear ends of the rockers. They are designed to install voltage screws.
8. The front ends of the rocker arm are designed to install the file. It moves with the help of special metal hinges. Before fixing the file, it is installed in a groove placed on the desktop.
9. The rocking chair is made from a single piece of durable material. At its upper end, a groove is made for installing the rocker arm, and near the lower end, a small rectangular hole is cut out for mounting the second rocker arm.

How to make a machine from a sewing machine?

From a sewing machine, an excellent jigsaw is obtained, which is equipped with a saw blade movement regulator. It is easy to make if you follow these instructions:

1. From the bottom of the machine, the thread weaving mechanism is dismantled. In some models, it may be located elsewhere.
2. To dismantle this assembly, it is necessary to remove a few bolts, and then remove the cotter pin and drive shaft.
3. The top protective panel is unscrewed. After that, the groove along which the sewing needle moves must be expanded to fit the file parameters.
4. The cutting element itself is also slightly modified. It is cut according to the length of the sewing needle.
5. It is not necessary to make an adapter for installing the cutting element. Instead, you can grind off the upper incisors a little and process the lower zone of the blade.
6. The nail file is inserted into the needle holder and work begins.

All the presented options for the manufacture of jigsaw machines are very successful. The resulting units are highly productive, and it is not difficult to make them. Depending on their skills, each master will be able to choose the best model of home-made equipment.

I didn’t want to put my expensive Makitovsky jigsaw on the table all the time, so I decided to buy another one to create a table. I very successfully turned up a jigsaw in the store "Our House" Caliber LEM-610E for only 862r. Included: wood file, side stop, vacuum cleaner adapter, spare brushes for the motor.

There was an outlet next to the display case and I looked at it in operation. Quite decently made, convenient, there is an adjustment of speed with a wheel, the inclusion is fixed with a button. The saw holder moves clearly without backlash.

It’s very fortunate that I was able to twist it in my hands before buying it, I wouldn’t risk ordering it from the Vseinstrumenty.ru website without knowing what it is. (Although the reviews about it are good) By the way, it costs more there and also pays for delivery ... so I successfully bought it in Our House. :)

Despite the advantages, he has a number of shortcomings that he saw on closer examination:

1) The file does not fit into the file holder. Apparently this is a copy of the marriage, but I did not waste my time on the exchange. Each saw has to be sharpened. (Although on the second jigsaw I won’t be able to use them after turning - it doesn’t matter, they are relatively inexpensive)
2) And this drawback can be seen even in the picture. The canvas is tilted strongly forward. (This was also corrected by placing tin strips under the back of the sole, achieving 90 o.
3) The speed control wheel turns hard, not very clearly and with jamming. At the minimum speed value, the tool cannot start at all (However, the same garbage with the start-up of my other "caliber" drills. This is unpleasant, but does not spoil life much)

As always, everything is in the spirit of minimalism. I did not make a separate switch. It is quite conveniently turned on with a standard button and fixed.

To do this, I bought a bracket in KrepMarket (this is a fastener from some kind of iron structure system)

By the way, I love CrepeMarket. Any screws, nuts, screws, fasteners. Every time I design something, I wander there in thought and collect the necessary details for myself.

The excess was cut and trimmed.

Back view. Now the distance between the bearings has a fixed file clearance of 1.2mm. I have a plan for the future: make a gap adjustment.

For thin materials can be omitted below.

As an experiment, I drew an asterisk and tried to cut it out evenly

For a 130mm file, the maximum possible thickness is 5cm. It turns out that there are very long files, I recently saw a 300mm file on the market

Sawed off a 1.5mm slice from a 40x40mm bar

Which is what I did. Now it can cut long workpieces with a width of 11.5 cm. The old L-shaped design also remained, and if more strength of the holder is needed, it can be installed again, although the new design has remained quite strong and reliable.

I also came up with the idea of ​​making a knife out of an old blunt file, grinding off its teeth and sharpening it.

They can figuratively cut material like a sealant. The cut is even. Much better than a utility knife. Pictured is a mouse pad.

Well, perhaps that's all. The table turned out to be reliable and comfortable. Now I have a tool on which I can do finer work than on a circular.

If you are into carving and making figurines or parts out of wood, plastic or similar material, you cannot do without a tool whose name is reminiscent of the distant Soviet past: this is a jigsaw.

Jigsaw jigsaw strife, now on sale there are both "pioneer" elementary manual models, and modern electric tools that only remotely resemble familiar saws.

You can also make a jigsaw yourself: in the technical literature and the network, many diagrams and drawings of electric jigsaws are offered.

It is not difficult to make such a device, and you will get significant benefits from it. You will be able to independently engage in the production of furniture you need and realize the most daring creative ideas for the interior.

An example of the manufacture of a jigsaw machine.

Homemade jigsaw for you to professionally make smooth details of the most bizarre shapes. First you need to decide on the most suitable design for you.

Technical description and components

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

It must include the following parts:

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

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

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

The types of saw blades are varied. They depend primarily on the consumable material. The dimensions of the parts for cutting are also important. Conventional saw blades for working with wood have a length of about 35 - 40 cm. They are able to saw parts made of wood or plastic with a thickness of no more than 100 mm.

With different types of materials, saw blades also change, mainly regarding their width: from 2 to 10 mm. Files can vary in the type of their tails - with or without pins. They are fixed in a special device for their tension and even sawing. To do this, they have spring-type springs.

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

Assembly drawing of a jigsaw machine.

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

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

Model range of jigsaw machines

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

Also, these devices are divided into varieties based on their fundamental design:

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

Jigsaws with bottom support

Scheme of machine design elements.

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

While the upper section contains only one sawing and cleaning device, the lower section contains many working elements: an electric motor, a switch, a transmission unit and a control unit. This design makes it possible to cut sheets of materials of almost any size.

Machines with double support

A home-made jigsaw with a double caliper differs from the lower caliper by the presence in the upper section of a special additional bar and a desktop with the ability to change the angle of inclination and overall height.

These models are designed to work with oversized parts. Such a machine is easier to make than the previous model. There are limitations in the materials with which you can work on it: their thickness should not exceed 80 mm.

Hanging machines

The name speaks for itself: the model is mobile, it works without a frame. The fundamental point in this design is the movement of the cutting file, and not the consumable. The module itself is attached to the ceiling, the saw is set in motion manually.

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

Graduated devices

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

Universal machines

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

How to make a jigsaw machine with your own hands?

We will not stop at the manufacture of the simplest machines: you can easily find such manuals with video support on the net. Let's talk about homemade jigsaw machines.

Assembling the machine with your own hands.

Here is the sequence of work for their manufacture:

• We make a bed from plywood sheet or plastic.
  The main thing is that the thickness should not be less than 12 mm. The function of the bed is a foundation, a working surface and a place for fixing mechanisms and an electric motor.
• We place a special rocking chair with an eccentric on the opposite side.
  We connect them using a metal bar with bearings. All fasteners in the design are screw.
• We make installation of an intermediate shaft.
  To do this, you need to prepare two bearings, put the pulley on the shaft as tightly as possible, then carefully fasten it with screws. Similar actions are performed with an eccentric.
• At the rocking chair, the amplitude of movements should change.
  To do this, you need to change the place of attachment of the screw, for which we drill exactly four threaded holes on the eccentric flange. The holes should be located at different distances from the axis. With a change in the place of attachment of the screw, the swing of the amplitude of the rocking chair will change.
• We make a rocking chair: this is nothing more than wooden rocker arms, into whose rear ends the screws that you built in the previous paragraph are inserted, these are tension screws.
  The rocker arms themselves are hinged to the rack. We fix the file on the front ends of the rocker arms. The previous and present stages must be carried out with special attention and care. The fact is that fastening the file is a fundamentally important thing. Rocker arms with plates are subjected to constant loads during movement due to their rigid screed with screws.
• For a rocking chair you need a stand.
  It will be better if it is made from a whole piece of material. We make a groove for the first rocker arm on the top of the rack. From the lower end we have a special rectangular opening for the second rocker arm.

Your . We wish you cool ideas and their high-quality implementation.

A jigsaw machine is a high-precision equipment designed for processing workpieces of varying complexity, made from different materials. To choose the right device, you need to study its design and familiarize yourself with some useful recommendations.

Basically, the einhell jigsaw, like its competitors, is used for the following purposes:

• Processing of complex contours from blanks;
• Cuts on the inner surfaces of the material, without affecting the outer contours;
• Furniture manufacturing;
• Manufacture of musical instruments;
• Creation of all kinds of blanks based on wood.

In addition to wood, even an assembled do-it-yourself jigsaw machine is able to work on plastic, ceramics, plexiglass, polycarbonate and a number of other materials. But still, the main material that jigsaws have to deal with is wood. Makita machines do an excellent job with this task.

Design

Studying the wmss 11 01 jigsaw kraton machine or its competitors represented by Makita, Bosch, Excalibur in order to assemble such a device with your own hands, we can say that structurally they all look about the same.

If you decide to make a homemade jigsaw machine, equip it with a CNC module in the future, then it is better to start manufacturing by studying the design of factory models.

The main structural elements of the machine are:

• Desktop;
• Electric drive;
• KShM (crank mechanism);
• Sawing tool;
• Tension mechanism;
• Auxiliary elements;
• CNC module.

If we take for example such machines as Makita, Proxxon, Dewalt, Hegner, Holzstar, Excalibur, DKS 502 Vario, Dremel or WMSS 11 03, they will be structurally close to each other. But the estimated price is from 6-10 thousand rubles. Therefore, the choice must be based on technical parameters and your personal needs.

1. The working table is used to place the workpieces to be processed. A number of machines are offered with rotary mechanisms for the table, which allows the operator to change the angle of inclination as needed, to perform inclined processing of parts. When performing a homemade jigsaw, you should think about grading to simplify marking. The size of the workpiece with which you can work depends on the size of the table. Therefore, base the choice on what materials you have to deal with. A standard table has a length limit of up to 30-40 cm.
2. The drive differs in power. Manufacturers such as Makita, Hegner, Dremel, Dewalt, WMSS 11 03, Proxxon, Holzstar, Excalibur, DKS 502 Vario offer a wide range of machines, each of which has different drive powers, nuances of the CNC module, etc.
3. KShM. This mechanism transfers the torque from the electric drive to the saw of the machine. The vertical movement of the file can be 3-5 mm at a speed of up to 1000 oscillations per 1 minute. Some machines, including Makita, Excalibur, WMSS 11 03, Dremel, Dewalt, Hegner, Holzstar, DKS 502 Vario, are equipped with a sawing frequency adjustment function. This allows you to adapt the machine to the specific type of material being cut.
4. File. With a length of 20-35 cm, it is able to cut a workpiece with a thickness of 10 cm. Saws differ in size and materials of manufacture. The choice is based on the density and characteristics of the materials to be cut.
5. Tension device. Due to it, the file receives the necessary tension at working points. Depending on the model, the device is based on springs or springs.
6. Auxiliary elements are primarily a dust extractor. If you decide to make a homemade jigsaw machine, we recommend that you provide this functionality. It can be organized using a conventional vacuum cleaner.

An ordinary electric jigsaw is sometimes quite capable of replacing a jigsaw-type machine. The jigsaw is not a stationary unit, but a hand tool. At the same time, the jigsaw has a wide range of applications. For domestic needs, it can be enough with the head. If, however, for work in a workshop, garage or in production, maximum cutting accuracy is required, then instead of a jigsaw it is better to purchase a full-fledged machine. Better yet, CNC. The CNC module will provide process automation. Through the CNC, the necessary programs are set, the machine independently processes the workpieces according to the specified algorithm.

A jigsaw cannot have a CNC, since it belongs to the category of a hand-held power tool. A stationary unit is in many ways better, because often the choice falls in its direction. This is evidenced by numerous customer reviews of Makita, Proxxon, Dremel, Hegner, Dewalt, Excalibur, Holzstar, WMSS 11 03, DKS 502 Vario, etc.

Criterias of choice

When such machines as Makita, Dremel, Holzstar, Dewalt, Proxxon, Hegner, DKS 502 Vario, WMSS 11 03 are on the market, the choice is complicated by the wide range. To make your choice a bit easier, think carefully about your machine requirements.

Based on them, you can understand whether the scheppach deco flex jigsaw is right for you, or maybe even prefer a homemade jigsaw.

1. Power. Dewalt, Hegner, Makita, Proxxon, Dremel, WMSS 11 03 equipment is offered in various designs - from household to professional. The choice in favor of professional devices with modern CNC should be done by specialists who regularly operate the equipment. The power of such devices is from 1 kW. The power parameters of household models from Dewalt, Proxxon, Makita, Hegner, Dremel are in the range of 500-950 watts. Power affects the depth of cut and the duration of non-stop operation. You should choose a more powerful model, even for domestic use, because they have a margin of durability.
2. The weight. The more powerful the selected Dremel, Dewalt, Makita, Proxxon, Hegner or WMSS 11 03 unit is, the more weight it will have. Since this is not a hand tool, it is important to take weighty devices. They form less vibrations, providing the necessary quality of processing.
3. Speed. Here the speed is measured in strokes per minute. Most machine tools from Makita, Proxxon, Hegner, Dremel firms, the frequency is in the range of 0-3500 units. Industrial models provide increased travel speeds for high precision machining.
4. Personal feelings. When choosing a machine, be sure to try it out. So you will understand how comfortable it will be to deal with him.
5. Stroke frequency adjustment. Modern machines Dremel, Proxxon, Makita, Hegner, Dewalt necessarily include the possibility of adjustment in the list of available functions. Only the range of adjustments for each model is different. Rely on the materials to be cut. The more diverse the blanks are planned, the wider the range of settings. In this regard, CNC models are convenient. They are adjusted to a specific material, which allows you to practically not take part in operations during the cut. This is the main advantage of CNC, for which many are willing to pay a lot of money.

Before you make a jigsaw machine with your own hands, based on drawings and videos, or purchase Makita, Proxxon products or a WMSS 11 03 machine, carefully consider your actions.

Homemade units are good in places, but they are far from the level of Makita machines. Makita has a very good reputation. Many units from Makita receive numerous positive reviews, laudatory criticism from experts. Yes, in addition to Makit, there are a number of other companies on the market that we talked about.

You choose whether it will be a machine from Makita, or decide to cut blanks on Proxxon, Bosch machines. For some, it’s even easier to make a device with your own hands than to pay for, of course, a high-quality Makita product.

Here is the general scheme of the jigsaw machine.

I had a homemade machine tool, I have already briefly written about it. Since I am a furniture maker, I made it from the remnants of LMDF. Cheap and cheerful :). I did not care at all about the appearance, as long as I worked. And he did a good job! On it, I understood all the nuances of sawing out of solid wood, such as walnut, oak, ash. Everything would be fine, but at the drive, and they were served by a Krees 350W construction jigsaw. 15 years of experience! At the drive, the speed regulator has "covered itself", it turns on immediately to the maximum and immediately tears the file. I did not find a native proprietary regulator. What kind of regulators I have not tried, and dimmers for chandeliers and regulators from shv. machines, vacuum cleaners. The desired result, namely a wide range of adjustment, I could not achieve.

The photo shows the principle of operation of the jigsaw. the construction jigsaw transmits oscillatory movements to the rocker, on which, in turn, the file is fixed.

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 one name. I found what I was looking for in the Makita brand store. Jigsaw 450 W. Wide range of adjustment, and does not yell like Chinese jigsaws! Quietly works!

Here is my new drive, Makita 4327.

I found a new drive, but it didn’t work to put it in place of the old one, the height is not suitable. I decided, rather than redo it, it is better to make a new one, taking into account the elimination of the inconveniences identified in 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.

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

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

And so! machine is ready!

Here is my new machine!

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

Trial cutting. The result is excellent! The Makita regulator does a great job. The machine works by noise like a household sewing machine.
