Designing an jigsaw with your own hands
The idea of creating a homemade electric jigsaw is most often due to the disadvantages that the factory hand tool has. You can make with your own hands a small table machine, which will include a pusher, reciprocating motor, saw tensioning system. You do not need complex drawings. if you understand the essence, it is easy to achieve the result.
The desire to create a homemade electric jigsaw can arise for several reasons:
- There is no power supply in the workshop, but it is possible to use internal combustion engines with low power.
- There are pneumatic motors but not enough compressor power for a production tool.
- Electric motor powered by battery or solar panel, but not powerful enough to run an electric tool.
- It is necessary to obtain the parameters of the saw’s movement, which are unattainable with a series-produced tool.
The jigsaw is easy to construct. A typical structure looks like this:
The unit is easy to adapt to any torque source. a pair of pulleys (one on the motor shaft, the other driving the crank mechanism) allows you to vary the ratio, reducing the load on the power unit and allowing you to get the desired speed (they are also responsible for the number of strokes per minute) on the actuator.
Powerful Electric Jigsaw for DIY
The machine, built according to the above scheme, can have the most different configuration, the material of manufacture is also chosen individually. An example of a ready-made installation has this view:
How is the table jigsaw built??
As you can see from the name, this tool is designed to be placed on the surface of the working table or workbench. Compact size allows you to work with a jigsaw in the workshop or garage, as well as at home. Electric jigsaw is an indispensable tool for making complex decorations from wood, figure carving on plywood and similar works.
It is necessary to consider in more detail the structure of a factory-made table jigsaw. This will allow you to understand the main features of the device and apply them to the homemade model.
The components of the electric jigsaw can be conditionally divided into 3 parts:
The principle of operation of the tool is as follows: an electric motor rotates the crank mechanism, which turns the rotational motion into reciprocating. The movements are transmitted to the movable frame, on which the saw is stretched.
Homemade device works using the same principle. To simplify the design, the movable frame can be replaced by an ordinary hand jigsaw.
- Electric jigsaw for manual use;
- Sheet plywood;
- set of clamps;
- 10 screws;
- an electric drill.
Mark out the slots in the plywood and carefully cut them out. If there is a pendulum stroke, it is necessary to disable it. Then we place a hacksaw blade in the slot and attach it there. Also make several slots on the plywood by drilling holes and connecting them to each other. Screws are placed in the slots made. To fix as a result the tool by means of clamps on flat surfaces is not difficult. The device is ready.
- Sheet steel (4 mm);
- sheet steel (1,5 mm);
- sheet of steel (1 mm);
- steel strip (2 mm);
- spring bar (0.9 mm);
- steel rod (7 mm cross-section);
- electric drill.
Using steel sheet (4 mm) we make a product in the form of a C-shaped frame, which will be the base of the jigsaw. Next, we attach it to the power drill. For this purpose we need to make a special collar from steel sheet (1.5 mm), which will provide the anchorage. On the edges of the base we fasten the spring bars. We need a sheet of steel (1mm) to create the clamps by which the saw will be attached. Similar clamps on the edges will also strengthen the C-frame. And from the steel bar you can make a crank, which will lead the jigsaw in action. For the connecting rod we need a steel strip, which will allow us to create a crank mechanism.
This marks the end of the jigsaw making process. Because of its mass, it is better to clamp the drill in a vise during work for safety reasons. And the working materials are better placed on flat surfaces.
General assembly instructions
Often craftsmen assemble their jigsaws from an ordinary household drill or from a refrigerator compressor. Thus, the hand jigsaw is converted into an electric tool. Some use a motor from washing machines. An interesting solution is to create a jig saw using an old sewing machine.
Manufacturing from improvised means
As a motor you can use any available household power tools: an electric screwdriver or an electric drill, which have a spindle speed controller will work fine. Materials can be used that are at hand: wooden bars, unnecessary sheets of plywood.
The main thing, in terms of safety, convenience and productivity, is the bed. It is made of plywood sheets with a thickness of 15 mm or more. Wooden parts are connected with screws. The joints can be coated with glue to increase reliability.
Wooden workpieces are used to assemble the lever assembly. The levers must have good strength. The most suitable wood is beech or oak. Straight pieces of old chair legs can be used.
The ends of the levers are sawn lengthwise. The saw’s mounts are inserted into the kerfs. The mount is a regular metal plate with two holes. The thickness of the plate is 2-3 mm. Through the upper hole, the mount is screwed to the lever, and through the lower hole, the jigsaw is clamped. Thumbscrews are used for clamping.
The lever system is fastened in the frame. The back of the arms are connected with a turnbuckle. Or, in another way, with a screw coupler. It is desirable that the levers are parallel to one another.
Crank joint is cut out of plywood, up to 1 cm thick. The rotation axis is marked with bearings. The bearings themselves are seated in holes that are drilled into the uprights.
Then the hand wheel and the lower arm are made. They are connected to each other by a connecting rod, which is also made of plywood. Then work table and swivel mechanism are assembled. From thin plywood is cut a rotary arc in which a slot is sawed out. The table is installed on the bed. The construction is tightened with a wing nut. It can be driven by an electric screwdriver.
Conversion from a hand jigsaw
First of all the working table for the mechanism is made. A sheet of metal or thick plywood is suitable for this purpose. Drill and saw holes in the worksheet for the cutting belt and fasteners.
Then the jigsaw table is placed on a regular table. After attaching, the guide rails can be assembled. To reduce vibration, it is enough to cut a rubber pad of the required size and put it between the jigsaw table and the base surface.
The above design is convenient because it can be easily disassembled, and it can be used again as a hand jigsaw.
Since the standard machine has springs that tension the saw, a rocker arm is necessary. One edge of the rocker is attached to the cutting element of the machine, and the other is under the tension of the springs. These uncomplicated actions will easily turn an ordinary electric jigsaw into a machine.
When operating the appliance, it is important not to forget to disengage the pendulum stroke before starting to cut.
Assembling from the sewing machine
From a sewing machine, you can also quickly and easily assemble a homemade jigsaw machine. And in this apparatus there is an interesting feature. the regulator of a file move, as on sewing machines there is a switch of speeds.
First, in the lower part of the machine you need to find the thread weaving knot. To do this, unscrew a few screws. Located inside, the cotter pin is knocked out and the drive shaft, which is connected to the yarn weaving complex, is removed. After performing this procedure, the top panel is unscrewed. The groove, along which the needle rode, expands slightly to accommodate the saw blade. The files themselves are shortened a little bit to the length of the needle. To fix the saw itself, you can make an adapter. But it is easier to cut the upper part of the cutting blade and sharpen the lower part. After that the file can be inserted in the place of the needle and the work can begin.
It is necessary not to forget about safety rules when working with jigsaws of any type. You should not leave the appliance switched on for a long time without supervision.
If the master has long hair, it is better to pick it up or use a special cap. It is better to roll up the sleeves on clothing. The room should be well ventilated. In the room where the carpentry work takes place, a first aid kit with first aid for cuts must be kept.
Self-made jigsaw jigsaws
It often happens that while working the jigsaw goes sideways. To prevent this from happening, you can use a homemade attachment. We will need a file in the shape of a triangle for the workpiece. A shank is made on it, as on the saw itself. It is enough to insert it into the power tool and start working.
You can also create a shank from a circular file. To do this, we cut a file to the length of the saw. At the machine for grinding we orient along the rib and grind the unwanted metal to 1.5 mm thickness or other size depending on the type of device. After that, we insert it into the hole of the jigsaw, and you can start working.
It is also possible to make a jigsaw shank for an electric jigsaw. To do this, we will need an ordinary jigsaw from the jigsaw, so that we make a blank from the blade with it. It has two functions. to cut wood and to cut metal. First of all we divide the workpiece into two equal parts using a ruler, then we make a deeper cut and draw two lines.
Using two wire cutters we notch along the cut and obtain a pair of blanks. One of them is designed to work with wood, and the other with metal. Now we put a jigsaw on the workpiece and repeat the contours. It is necessary to cut a place under the lock, where the saw will be attached to the jigsaw, and mark the length.
Myself you can also make a compass for a jigsaw, a guide and other items that will greatly facilitate the work with such a homemade device.

How to make a jigsaw with your own hands?
The easiest option is to make a machine tool. Self-made jigsaw machine is probably the best solution. Variations and drawings. a great many, they can easily be found on the Internet. This is all a consequence of the desire to create a unique and inimitable tool. However, the principle of work will always be exactly the same.
Classification of devices
Specialists classify jigsaws according to the type of design. The special design of the mechanism determines the possibilities for machining wooden products.
Jigsaws are classified according to their design.
Models with a bottom slide are the most common. The bed of a bench-mounted factory unit has 2 halves. the lower and upper one. Sawmill and chip cleaner models are located on the upper part of the bed.
Lower frame contains controller, motor, main gear, on/off button. This machine allows working with any material and of any size.
The presence of two slides in a jigsaw advantageous because the upper half of the bed has an additional rail. This jigsaw is ideal for cutting small parts. Workpiece thickness for both models must not exceed 8 cm. The worktable of such machines, as a rule, has the ability to adjust the height and tilt angle.
Devices on the suspension have no fixed bed, but are distinguished by their mobility. The material to be treated is set stationary, while the craftsman moves the working module. Since the latter is attached to the ceiling, the thickness of the material is not limited. The tool moves by hand, independent of the bed. This makes it possible to make patterns of complex shapes.
The presence of the scale of degrees and stops is suitable for those craftsmen who make processing according to drawings. Marking allows you to avoid errors at work. On the market there are universal machine models, which allow you to do several operations. Such a machine allows you to drill, cut, polish and sand. The cost of such machines will be much higher, but it is more comfortable to work with them. These are industrial pieces.

Table electric jigsaw with their own hands
Lately I’ve been very interested in jigsawing, I don’t even know why that would be. It all started with the fact that I needed to cut some gears from plywood.
And so it goes. At first I sawed the gears by hand, then I thought, it is certainly good to swing a hand jigsaw, but if you automate the process, it will be much faster!
So, first of all, this is a handheld jigsaw for artistic sawing.
(all pictures in this article were found on the Internet)
To saw, you need saws, they’re as thin as wire with sharp teeth. These saws used to be sold in packs of 50., recently went into a store, so these “bishops” started selling them by the piece. You can break a pair of these saws in an evening.
For sawing we also need a special table, it can be a board with a tapered slot, screwed to the table with screws or clamping.
For ease of attachment of saws in the machine, it is better to use a special device that will squeeze the contour of the jigsaw, so you can easily change the saw without effort. With the help of a wooden eccentric is compressed.
And now about automation. In the following photo you see a table electric jigsaw of the factory type, on the Internet you can find a sea of different modifications. Costs this thing is not very expensive, but even if you really want to in my city I can not find such, and, in principle, not to what.
Industrial machines is certainly good, but I’m likely to use them a couple of months and give up the activity, and in general, such a machine tool, as I learned you can easily assemble yourself from plywood and wooden bars.
The following photo uses an industrial hand jigsaw and a spring to return the jigsaw.
So, we can easily assemble a table electric jigsaw at home. I personally did so, but I have a special design, in this article there are no pictures of me, but I’ll certainly lay out, as well as video in the work.
The drawings of a home-built jigsaw, although much of what is outlined here can be replayed to your liking.

When cutting sheet material. plastic panels, laminate, cement board, plywood, chipboard, and other without the jigsaw can not do. Electric jigsaw is indispensable if there is not a small repairs with the flooring and finishing of the walls paneling.
And for sawing various small workpieces, including metal, electric jigsaw is very helpful, greatly reducing manual labor.
The peculiarity of an electric jigsaw is that it can be used to make shaped cutouts, as well as to chamfer and make cuts at an angle.
- The worker had two hands free when working with the material;
- To ensure that the efficiency of material processing did not depend on the skill and physical characteristics of working with a hand jigsaw, t.к. Long work with it is much exhausting;
- Allowed to perform the sawing of the workpiece at a certain angle.
To perform these operations, we need a desktop jigsaw, which costs a lot of money. Having in the presence of a hand jigsaw, you can try to “turn” it into a jigsaw table.
So let’s begin, as a driving device I used an electric jigsaw, which has undergone certain modifications. After careful measuring of the jigsaw, I began to cut all the elements of the future enclosure from the furniture panels.
For the base was used plywood with a thickness of 10 mm.Initially it was decided to use a wooden bracket to fix wall boxes.The prepared enclosure was painted.
