A very fast and fairly compact tool, it can be incredibly useful for making straight and curved cuts. Appearance and the functionality of the jigsaws sold are impressive, making one believe in the incredible complexity of the design of these devices. In fact, to recreate such a mechanism, it is enough to understand the principle of its operation, have instructions and the desire to do something with your own hands. It is not at all necessary to be an expert in technology with many years of experience (although this quality will not be superfluous). Next we will carry out detailed analysis average jigsaw model with drawings, and we will provide two detailed manuals for independent production of such a tool.
The basis of any electric jigsaw is the following components: an electric motor, a gearbox and a rod with a saw blade clamp. To the secondary ones, but no less important elements, include the start button, support roller, cooling fan and soleplate. As additional functionality, many models have a pendulum stroke, a dust collector, lighting and a laser guide. We will not touch upon the operating principle of the latter, and will move on to a description of the interaction of the main elements of the mechanism.
The high-frequency movements of the jigsaw saw blade originate from an electric motor, started by pressing a button or directly from the network. Rotation is transmitted along the shaft to a special “gearbox” mechanism with an eccentric, which interacts with the rod, forming a reciprocating movement. The mount installed at the end of the rod holds the saw that makes the cut. To minimize the load on the rod with the gearbox, the rear edge of the saw blade rests against the support roller. In this way, all components of the device are involved to perform the main task of sawing all kinds of materials.
For a craftsman who understands the principle of operation of any mechanism, it will not be difficult to reproduce it, especially if he has detailed instructions. The bicycle has already been invented, and to make it yourself, it is enough to have a set of necessary parts and tools. The guide below will demonstrate in detail how to make a jigsaw with a complete listing of the elements and tools required for the job. The product being created is not a stationary device, but a mobile saw with an electric drive. The device has not much power, but it is enough to cut wood up to 5 mm thick.
Required materials:
Assembling the jigsaw will begin by cutting out the handle from a larger block. To do this, it is enough to make a cut, giving the rectangular board L-shape as in the photo. The dimensions of the cut part are set “by eye”, based on the preferences and size of the operator’s hand.

Today I want to tell you how to make a jigsaw table with your own hands. Perhaps some will say: why can you saw on any table? With such success, we can ask: why use an electric jigsaw, after all, you can cut it with an ordinary, manual one.
When you cut with a jigsaw, you move the file to the side. I looked on the Internet and initially I wanted band saw, there is no way to buy it, and making it is very difficult and expensive. So I decided to make a table for an electric jigsaw.
First of all, let's decide on the material for the table and its size.
I found chipboard in the garage, so I’ll use it to make a table and a lid for it. I will make the bar itself from profile pipe the size of which is 25 × 25 × 25, height 110 mm, length 515 mm, length of perpendicular corner 20 mm.
For the part of the device where the saw clamp is located, in other words the lock, I used two bearings. I secured the metal bar with a “lamb” so that it would be possible to adjust the level of elevation in height of the part that we are cutting off.
Let's move on to making the table. Table size: length 540 mm, width 400 mm, base 435 mm, depth 350 mm. and height 250mm.
I attached a jigsaw under the table with screws and washers. I left the front part of the table open so there should be access so that, if necessary, you can replace the file, adjust the speed or amplitude, in a word, to make different settings for the jigsaw. Of course, in the future I plan to improve the table by adding doors to it, this is not only for aesthetics, but then the noise will be reduced.
For greater convenience when cutting, I made a ruler-stop. I made it small because when we drink at the table special effort not included (compared to a circular saw, where you need a stronger ruler to cut the parts evenly). The structure of the ruler is very simple; here I used an 8-inch furniture nut, and on the other side a screw that can be easily tightened with a screwdriver. You can screw it to the table manually, but if we do this with a screwdriver it will be more reliable.
The ruler moves freely on the table, which is convenient when cutting.
The table-machine for the jigsaw is ready, you see there is nothing complicated in its manufacture.
IN Lately I was very interested in cutting out with a jigsaw, I don’t even know why. It all started with the fact that I needed to cut out several gears from plywood...
And off we go. At first I cut out the gears by hand, then I thought, pumping the muscle with a hand jigsaw is of course good, but if you automate the process, it will be much faster!
So, first of all, let's get to know this manual jigsaw for artistic cutting.
(all photos in this article were found on the Internet)
To saw you need files, they are thin as wire, with sharp teeth. Previously, such files were sold in a pack of 50 pieces, recently I went to the store, and these “bimesmen” started selling them individually. You can break a couple of these files in an evening.
For cutting, we will also need a special table, it can be a board with a conical slot, screwed to the table with screws or a clamp.
To make it easier to attach the files to the machine, it is better to use a special device that will compress the contour of the jigsaw, so you can easily change the file without effort. With the help of a wooden eccentric, compression occurs.
And now about automation. On next photo you see table jigsaw factory type, you can find a sea of different modifications on the Internet. This thing is not very expensive, but even if I really want it, I won’t be able to find it in my city, and in principle there’s no need. 
Industrial machines are, of course, good, but I’ll probably use them for a couple of months and give up on this activity, and in general, such a machine, as I learned, can be easily assembled yourself from plywood and wooden blocks.
The following photo uses an industrial manual jigsaw and a spring to return the saw.
So, we can easily assemble a tabletop jigsaw with our own hands at home. I personally did just that, but I have a special design, there are no photos of me in this article, but I will definitely post them, as well as a video in progress.
If you are engaged in carving and make figures or parts from wood, plastic or similar material, you cannot do without a tool whose name is reminiscent of the distant Soviet past: a jigsaw.
There are differences between jigsaws, now both “pioneer” elementary manual models and electric ones are available for sale. modern instruments, only vaguely reminiscent of the usual files.
You can make a jigsaw yourself: technical literature and the Internet offer many diagrams and drawings of electric jigsaw machines.
Making such a device is not difficult, and you will get significant benefits from it. You will be able to independently produce the furniture you need and realize the most daring creative ideas for interior.
An example of manufacturing a jigsaw machine.
A homemade jigsaw allows you to professionally make smooth parts of the most bizarre shapes. First, you need to decide on the design that is most suitable for you.
The schematic diagram of any jigsaw machine is the same for different models.
It must contain the following parts:
Consumables are fixed on the working surface. In advanced models, there are special devices for rotating movements of the part; in them, the working surface can change the angle of inclination.
The surface dimensions will depend on your production and creative plans: what large sizes the parts you are going to cut, the larger your production table should be. Traditional sizes are usually around 30 – 40 cm.
There are a wide variety of types of files. They depend primarily on consumables. The dimensions of the parts for cutting also matter. Conventional saws 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 The materials also change and the files also change, mainly in relation to their width: from 2 to 10 mm. Files can differ in the type of their tails - with or without pins. They are fixed in a special device for tensioning and even sawing. For this purpose, they have springs of a spring type.
Another important one: the crank assembly. Its function is difficult to overestimate: it is it that transmits movement from the drive to the saw, turning rotational movement into a progressive one.
Assembly drawing of a jigsaw machine.
Due to this, the file begins to oscillate at a high frequency, the speed of such oscillations is on average about 800 - 1000 revolutions per minute. It is important to remember 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 these are 600 and 1000 rpm.
Most often, in the power of an electric drive, the range of values is huge: from 90 to 500 W.
These devices are also divided into varieties based on their fundamental design:
Diagram of machine design elements.
The most used and popular models are machines with lower support. Their feature is the division of the working bed into upper and lower parts.
If in the upper section there is only one device for sawing and cleaning, then in the lower section there are many working elements: an electric motor, a switch, a transmission unit and a control unit. This design makes it possible to saw sheets of materials of almost any size.
A homemade jigsaw with a double support differs from the lower support by the presence in the upper section of a special additional bar and a work table with the ability to change the angle of inclination and overall height.
These models are designed to work with oversized parts. This machine is easier to make than the previous model. There are restrictions on the materials that can be worked with: their thickness should not exceed 80 mm.
The name speaks for itself: the model is movable, it works without a stand. The fundamental point in this design is the movement of the cutting file, and not the consumables. The module itself is attached to the ceiling, the saw is driven manually.
All this provides serious advantages: in this way you can create the most complex patterns, the surface dimensions are not limited in any way.
The presence of stops and a degree scale make it possible to work according to technical drawings, without the slightest error.
Such devices are usually called jigsaws. Their feature is the ability to perform several operations such as grinding, polishing, sawing, etc.
We will not dwell on the manufacture of simple machines: you can easily find this kind of manuals with video support on the Internet. Let's talk about homemade jigsaw machines.
Do-it-yourself machine assembly.
Here is the sequence of work for their manufacture:
Yours. We wish you great ideas and their high-quality implementation.
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 Rotary table, 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 small size specifications 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.
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:
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 is the same in most cases - they take a manual jigsaw as a basis and repurpose it.
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. Factory handheld device- this is the 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:
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 a manual version of the tool that can be used on homemade machine- it’s cheaper that way. 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. the main problem lies in the file - it is too wide in manual models. Because of this, fine woodwork is difficult to perform 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:
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 design self-made. 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.
