We design a jigsaw with our own hands. Homemade jigsaw - design and manufacture at home Do-it-yourself wood jigsaw drawings

Sawing small pieces of wood is done with a jigsaw. The device is small and usually has an electric drive. Factory models differ in their characteristics and cost. With small volumes of wood processing, it makes sense to make jigsaw machine independently, from improvised means. This requires a few factory parts.

A factory-made jigsaw is a 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 desktop. The size of the workpiece depends on its size. Some models have Rotary table, which makes it easier to work with the part - visibility improves. The presence of graduation facilitates the marking of the material.

Average characteristics of factory machines:

Special purpose models may have radically different characteristics. There are specifications Not large sizes, for processing small parts. As well as models of large sizes, the industry also produces for retail sale. But such options will differ in high cost.

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

Experts classify jigsaws by type of construction. Features of the execution of the mechanism determine the possibility of processing wooden products.

Classification is carried out depending on the design of jigsaws.

Device types:

With bottom support.
Double caliper.
On a pendant.
With degree scale and stop.
Universal.

Models with a lower caliper are most widely used. The bed of the desktop factory device has 2 halves - the lower and the upper. The sawing and chipping model is located on the top of the bed.

The bottom frame contains a controller, an electric motor, a main gear, an on/off button. Such a machine allows you to work with any materials and any size.

The presence of two calipers in the jigsaw is beneficial in that the upper half of the frame 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 desktop of such machines, as a rule, has the ability to adjust in height and angle of inclination.

Suspended devices do not have a fixed frame, but are distinguished by their mobility. The processed material is fixed, 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 do the processing according to the drawings. The markup allows you to avoid errors during operation. There are universal machine models on the market that allow you to do several operations. Such a machine allows drilling, cutting, polishing and grinding. The cost of such devices will be much higher, but it is more comfortable to work with them. These are industrial examples.

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

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

Assembly order:

Make a base table. 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 side by side.
A factory device is fixed at the bottom of the support table. Holes for fasteners are made next to the hole for the saw blade. Screws with a countersunk head 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 hats of the wines, which will cause inconvenience in work.
The design is fixed on a wooden table.

The advantage of creating a do-it-yourself jigsaw machine is that the factory tool can be detached at any time. When necessary - in the hands of an ordinary manual jigsaw. Therefore, it is better to purchase a manual version of the tool that can be used on a homemade machine - it's cheaper. Stationary devices are expensive.

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

jigsaw manual type as the main device for the machine has disadvantages. The main problem is the file - it is too wide in manual models. Because of this fine work it is difficult to perform it on a tree - the curvature of the lines is limited.

The previous design is simple and does not have additional details that make it easier to work with wood. 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 on the file.
Fix the file between two rollers. They serve as guides for a thin file.
A stationary factory device is used as a drive system of two rocker arms. Between the latter, a file is pulled. The movement is transmitted from the factory device to the lower rocker of the file.

design upon purchase or self-manufacturing you have to choose based on personal preferences and the desire to poke around in technology. The use of guide rollers is a less popular option - its reliability is lame.

Modernization by installing rocker arms is common. It is better that at the same time the factory device serves only as a drive for sawing a jigsaw. To do this, turn off the pendulum stroke in the tool.

The heir to the property of grandparents often gets an old sewing machine. She has already served her purpose in tailoring, as more precise equipment is now being produced. In the absence of a jigsaw in the household, you can not spend money on its purchase. It is made by hand from sewing machine.

Procedure:

Now jigsaw for figured cutting ready for plywood. WITH manual drive will work harder, because the legs will get tired. An additional disadvantage will serve as vibrations from the force impact on the tool. The electric drive of the machine, converted into a jigsaw, partially solves the problems of vibrations.

An expensive jigsaw can be replaced with a design own production. It will not be inferior to anything in terms of its qualities and functionality, if you take a responsible approach to the assembly process. 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 the option with a sewing machine, this will not be possible. If desired, markings are applied to the table to make it easier to measure the details in the process.

How to remake a manual jigsaw
machine from sewing machine

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

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

Device and principle of operation

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

Power electric jigsaw may be small. For domestic purposes, a 150 W unit is sufficient.

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

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

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

Assembly instructions

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

How to remake a manual jigsaw

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

If necessary, the machine can be quickly disassembled.

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

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

Machine from a sewing machine

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

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

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

Many people know from childhood the fun of sawing with a jigsaw. The technology is simple. But despite the seeming ease and simplicity of work, you can get very beautiful lace made of wood or plastic. This is a very slow process that requires perseverance and patience. To facilitate labor, jigsaw machines were developed. They are functionally divided into two groups: with manual and electric drive.

Muscle-driven jigsaw device

Homemade machine is easy to make. You can find many drawings of this plywood product. With a jigsaw, with your own hands and with an improvised tool, a simple but functional device is assembled in a short time.

The scope of jigsaws is extensive. They are used for cutting figured products from a variety of different materials. And also machines are needed when cutting lumber. In this case, the outer contour of the workpiece remains intact. If you use different nail files, then homemade jigsaw perfectly handle natural wood, plywood, chipboard, plastic, metal, in particular aluminum.

Examples of drawings of a do-it-yourself jigsaw machine, which works on muscle strength, have been repeatedly cited in various magazines of the Soviet era.

Nail files for such a jigsaw machine are produced in the form of a flat blade.

The main parts of the machine:

Stanina (A).
A working table with a slot for a saw (B).
Large drive pulley acting as a flywheel (D).
Small drive pulley. The drive is combined with a crank mechanism (D).
Levers (B).
A pedal that spins the flywheel through the crank assembly (E).
Saw Tension Unit (G).

The master, constantly pressing the pedal with his foot, spins the flywheel. Through the belt, the movement of the flywheel is transmitted to the second pulley. Which, in turn, makes the crank mechanism with the saw blade move.

If the flywheel is correctly balanced, without distortions and with a uniform, correctly selected mass, then the nail file achieves good smoothness. Such a plywood sawing machine allows you to quickly produce many simple similar products. Cutting time and effort is significantly reduced.

With this design of the machine, the size of the initial workpiece is limited. It depends on the length of the levers (B). When the pattern becomes more complex, it is necessary to rotate the product around the saw.

Since the foot drive does not provide a completely uniform stroke and limits the freedom and imagination of the master, most often such machines are replaced with electric ones.

The design of the electric jigsaw

Electric jigsaw tape - this is a household universal fixture for the manufacture of souvenir products, furniture, various interior items. There are many options for the manufacture of such machines. But the main elements on which product quality and ease of use depend are the electric motor and the blade of the blade.

Main structural elements:

Saw blade.
Crank mechanism.
Drive part.
Tape tensioner.
Bed or desktop.
Various accessories.

Device and principle of operation

Alteration from a manual jigsaw

The first step is to make a desktop for the mechanism. Suitable for these purposes a metal sheet or thick plywood. Holes are drilled and cut out in the worksheet for the cutting tape and fasteners.

Then the jigsaw table is placed on regular table. After fixing, you can assemble the guide rails. To reduce vibration, just cut the rubber gasket right size and put between jigsaw table and main surface.

The above design is convenient in that it can be easily disassembled, and it can be used again as a manual jigsaw.

Since the standard apparatus has springs that tension the saw, a rocker is needed. One end of the rocker arm is attached to the cutting element of the machine, and the other is under spring tension. These simple actions will easily turn ordinary electric jigsaw into the machine.

When using the device, it is important not to forget to turn off the pendulum stroke before starting cutting.

Sewing machine assembly

From a sewing machine, you can also quickly and easily assemble a homemade jigsaw machine. Moreover, this device has interesting feature- a nail file stroke regulator, since there is a speed switch on sewing machines.

First, at the bottom of the machine, you need to find the thread weaving knot. To do this, unscrew a few screws. Inside, the cotter pin is knocked out and the drive shaft is removed, which is connected to the weaving complex. After completing this procedure, the top panel is unscrewed. The groove along which the needle traveled expands slightly to fit the saw blade. The nail files themselves are slightly shortened to the size of the length of the needle. To fix the saw itself, you can make an adapter. But the easiest way is to grind off the upper part of the cutting blade and sharpen the lower one. After that, you can insert the nail file in place of the needle and get to work.

When working with jigsaws of any type, you should not forget about the safety rules. Do not leave the device turned on for a long time unattended.

If the master long hair, then it is better to pick them up or use a special cap. It is better to roll up sleeves on clothes. The room must be well ventilated. In the room where carpentry work takes place, a first aid kit with first aid for cuts must be kept.

A desktop jigsaw is useful for every craftsman who cuts out thin details. However, it is far from always possible and meaningful to acquire a full-fledged machine. In this case, get down to business and do it yourself!

The device of the jigsaw machine - what lies inside?

Jigsaw machines are more about special tools than about devices that are needed as experienced master, and the amateur hosting in the garage. Their purpose is reduced to a special task, namely, cutting out complex curvilinear contours from sheet materials. A special “chip” of such machines can also be attributed to the execution of the cut without violating the integrity of the external contour. Most often, sawing occurs on wood and derived materials (plywood, chipboard, fiberboard), although modern machines equipped with appropriate nail files are able to work with other materials, such as plastic or drywall.

Such equipment has found application in the music industry (manufacturing musical instruments) and, of course, in furniture. They buy such units and lovers of tinkering in their own workshop. The device of a traditional jigsaw machine, designed according to all the rules, is as follows: working surface, on which the saw is brought out, hides the drive (electric motor) and the crank structure under it. The tension mechanism can be located both below and above the machine.

To process a part, it must be placed on the desktop. 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 swivel mechanism, can be marked, which greatly simplifies and speeds up the work. It is the length of the cut that depends on the length of the desktop - most models are limited to 30-40 cm. The power of the electric motor is an important, but still far from the most fundamental factor, since the machine has a huge margin of unclaimed power. For example, for a home workshop or even a small production, a “engine” of only 150 watts is enough.

Crank mechanism - much more important detail, because in this case it depends on it the quality of the transfer of the torque of the drive into the forward-return motion directed to vertical plane by means of a saw.

Standard jigsaw machines are considered devices with a range of motion in the region of 3-5 cm at an oscillation frequency of up to 1000 per minute. In many models, a change in speed mode is provided for different materials. The jigsaw itself is usually made up to 35 cm long and is able to cut 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 of 0.6 mm to 1.25 mm.

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

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

On the web you will find many different designs homemade machines, but most of them come down to reprofiling into this machine. Using your ingenuity and watching the video, you can easily make a homemade jigsaw machine from this tool. You only need to modify the jigsaw a little. In fact, it plays the role of a machine tool drive and a crank mechanism, 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 rework, however, in reality, only you can make an apparatus that meets your needs. So, the first step is to make a support table, for which they most often use sheet metal. In it you need to make a slanted oblong hole for the saw blade and holes for fasteners (countersunk screws are recommended), and attach the jigsaw to the bottom of the support table.

This design can only be strengthened on a wooden table. You can go beyond this and install guide rails. The convenience of such an apparatus lies in the fact that in addition to performing functions that are not entirely inherent in it, you can always disconnect the drive and with a flick of the wrist turn it back into a manual electric 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 an assembly inherits not only the advantages of the tool, but also its disadvantages, in particular, a nail file that is too wide for filigree work, which significantly limits the curvature of the lines. If there is a need for this, there is a way out. So far, our machine differs from the classic jigsaw unit by the absence of springs that would provide sufficient tension for the nail file. But to build a simple rocker, which on the one hand will be under the tension of the springs, and on the other hand fixed on a nail file, is quite easy.

There is another option - to clamp the nail file between two guide rollers, but the first option is still more reliable. Remember to turn off the pendulum motion on the jigsaw before you start using it. homemade machine. There is another design - if your tool is powerful enough, then it can only serve as a drive in a design of two rocker arms, between which a nail file is stretched. The movement is transmitted by means of a nail file fixed on the lower rocker arm.

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

If you inherited a foot or hand sewing machine from your grandmother or mother, consider yourself the owner of an excellent jigsaw! Of course, for this you need to “conjure” a little over the machine. First, remove the thread weaving device, which is usually located at the bottom of the machine. There is nothing complicated in this, it is enough to unscrew the 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. Focus on the needs and width of the nail file that you will use in your work. Jigsaw blades of this kind also need to be slightly modified, namely cut to the maximum length of the needle that could be used on this machine. After grinding off the upper teeth and sharpening the lower part on the point, you just have to insert the nail file into the needle holder and test your machine in action!

An electric jigsaw is a type of woodworking equipment. Currently, the choice is presented not only in the usual manual version but also in electricity. These models, for example, Vario 502 dks, dremel have high performance, quite easy to use, equipped with a large number of removable components.

These devices can be used in household as well as in production. Today, such a mechanism can be bought ready-made or made by hand, for example, from an old sewing machine.

1 Technology of use

The main working element of a manual jigsaw is small nail files, which usually have a length of 50 to 120 mm. This is driven by an existing electric motor and performs translational movements vertically during the 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 sole of the equipment. Such fixation makes it easier for the worker to operate the system and freely adjust the angle of the tool. The safety of the operator in this design is ensured by the presence of a special screen.

These models appeared in mass sale in last years. Previously, they tried to make 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 electric 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 replacement sheets.
Greater reliability in use: due to the wide web of such a mechanism, it is possible to avoid breaking parts made of wood, tiles during processing, and also to perform any complex contours with a minimum of effort.
The ability to feed the wood blank with two hands by attaching it to the canvas. Previously, without such a device, working with hand-type samples was much more difficult.
Simplicity in the processing of any canvases - even a relatively small the jigsaw can easily handle wood with a thickness of 50 mm, not to mention more powerful models.
Wide range of processing options.

Among the disadvantages of using such a device, a short stroke of the samples is usually noted, due to which the work with thick sheets becomes much more difficult.

Also, the inability to make the bending radius as small as when using a manual sample (due to the features of the saw blade attachment).

2 Scope of machine tools

Modern electric jigsaws are applicable for following works to choose from:

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

A desktop jigsaw is used mainly for processing wooden blanks. Most often it is used in the manufacture of furniture, musical instruments. In recent years, they have also often been used for the production of decor items, as well as souvenirs.

2.1 Consumables

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

Usually equipping a jigsaw machine with their own hands and buying files for it, experts recommend navigating the choice Supplies to the following features:

For sawing on blanks made of wood or plywood, saws are selected in increments of 2-4 mm.
Metal samples, as well as plastic, are usually processed by choosing 1-2 mm files, including spiral ones. Masters who form reviews on the use of such components recommend stopping here on models with a wavy edge. The choice of those is very large.
When working with tiles, special saw blades with an abrasive coating are used.

You can choose these elements for processing wood and other materials not only based on reviews, but also based on specifications equipment of your choice.

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

Also, do not forget about additional elements such a design, which, for example, in the models Dewalt, Dremel, Holzstar, Vario 502 dks include 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 their own hands, is presented on the market in a huge amount various products. Their choice is really wide. Among them are the 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 necessary to analyze the device in all respects. And then you can get the perfect component for any task. You can also assemble a desktop jigsaw with your own hands using general recommendations for the production of such devices.

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