Desktop jigsaw machine. How to make a jigsaw with your own hands? How to navigate models from different manufacturers

Since childhood, we are familiar with the technology of cutting with a jigsaw. The principle is simple - the stationary part is placed on a support with a technological cutout, the sawing is done by moving the file. The quality of work depends on the firmness of the hands and the skill of the employee.

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

Simple construction from the last century

Also in the magazine “ Young technician»Drawings were offered on how to make jigsaw do it yourself. Moreover, the design does not imply an electric drive, the drive works from muscle power, like a knife grinder.

The machine consists of the main parts:

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

With the feet of the foot, the master sets the flywheel (D) in motion. With the help of a belt drive, the crank mechanism (D), connected to the lower lever (B), rotates. A file is stretched between the levers, the degree of tension is adjusted with a lanyard (G).

With a well-balanced flywheel, the saw blade runs smoothly enough, and such a homemade jigsaw machine allows you to massively saw the same type of workpiece, saving time and effort. In those days, jigsaw blades were produced in the form of a flat, unidirectional band.

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

From a jigsaw to electric one step

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

For slitting and sawing small parts jigsaws are used from wood, plywood, plexiglass, plastics and other materials various designs and types. These can be manual ("pioneer"), mechanical and electric jigsaws. Various magazines cited diagrams of homemade jigsaw machines that were driven by an electric motor and even electric drills. Read how to make a homemade jigsaw machine in this article.

Using a desktop jigsaw at home, you can make furniture, beautiful patterned shelves, and much more. The mechanism allows you to cut straight and curved parts from wood, plastic and dense foam. In order for a homemade device to fully meet the requirements, it is necessary to carefully select the appropriate design.

Design and specifications

The device of any model of jigsaw must contain:

saw;
crank assembly;
drive unit;
saw tensioner;
Desktop;
auxiliary mechanisms.

The processed material is placed on the work table. Some models are equipped with a rotary device that changes the slope of the surface. To make it easier to do the marking of the material with your own hands, a graduation is applied to the surface.

How bigger size table, the longer the cut can be made. On average, this figure is 30 - 40 cm.

Drive power for homemade bench machine is about 150 watts.

The crank assembly converts the rotary motion of the drive into reciprocating and transfers it to the saw. On average, the frequency of vibration of the saw blade per minute is 800 - 1000. The amplitude of vertical movement is not more than 5 cm. Some models allow you to select the speed of movement depending on the properties of the material.

File hand jigsaw can work with wood, plastic with a thickness of no more than 10 cm, with a length of up to 35 cm. For different types materials and work files vary, their width is 2 - 10 mm.

A manual tensioning device secures the saw blade for even cutting, it consists of coil or spring springs.

Types of machines

Structurally, all jigsaw devices can be divided:

with lower support;
with double support;
on a suspension;
with a degree scale and stops;
universal.

The most common are models with a lower support. Their bed is divided into two halves: a lower and an upper one. At the top there is a cutting and cleaning module. At the bottom there is a control module, an electric motor, a transmission mechanism and a toggle switch. Allows to process sheets of material of any size.

Models with double support differ in that there is an additional rail on the upper half of the bed. Such devices are good for creating oversized parts. They are easier to install than the previous version. Both models allow processing material no thicker than 8 cm. The machine is supplied with a work table with adjustable angle and height.

Suspended machines are not equipped with a monolithic bed, they are very mobile. During processing, the cutting unit moves, not the material. The working module is usually attached to the ceiling by hand, so the size of the material is unlimited. Cutting tool moves by hand independently of the bed, creating very complex patterns.

Machines with a degree scale and stops are good for precise drawing work. The design allows you to avoid errors. Universal jigsaw machines can perform several operations associated with cutting: drilling, polishing, grinding.

Making a machine with your own hands

Homemade drawing table jigsaw: 1 - rocking insert (2 pcs.), 2 - shackle (2 pcs.), 3 - table, 4,6 - screws, 5 - pull rod, 7 - eccentric, 8 - base, 9 - axes of earrings, 10 - upper rocker arm , 11 - the axis of the rocker arm, 12 - the lamb, 13 - the cross member of the tensioning screw (2 pcs), 14 - the tensioning screw, 15 - the rocker arm, 16 - the lower rocker arm, 17 - the box, 18 - the double-ribbed pulley, 19 - the intermediate shaft, 20 - rack bushing, 21 - table plate, 22 - bearing with cover (2 pcs.), 23 - electric motor pulley.

In the drawing of a do-it-yourself desktop machine, the number of nodes must be minimized, these are: a rocking chair with a fixed saw, a bed and an electric motor. You can take the engine from an old electric car.

Owners of a manual jigsaw are more fortunate. You can make a stand from a sheet of plywood and attach a jigsaw to it. To fix the jigsaw with your own hands, you will have to make holes in the base of the tool. The most simple model ready.

Now about more complex and functional ones. The bed is made by hand from 12 mm plywood, thick plastic or PCB. It is a base, a box for placing the engine and mechanisms, and a work table. On the other hand, we have a rocking chair with an eccentric. They are interconnected by a metal plate with bushing bearings. The whole structure is fastened with screws. Prepare a pair of bearings to mount the intermediate shaft. The double-ribbed metal pulley is pushed onto the shaft as tightly as possible, the screw connection is secured. In the same way, you can make an eccentric.

To change the amplitude of movement of the rocker, four round ones are made on the eccentric flange through holes with threads, removed from the axis by different distance... By changing the location of the screw, the swing of the rocking chair is adjusted. It is a pair of wooden rocker arms hinged to the rack. The rear ends of the rocker arms contain through cuts and tension screws are inserted into them. A file is fixed at the ends in front, movable due to metal hinges. Before fastening, the file is inserted into the groove. work surface table.

The file attachment mechanism is very important. When making homemade device with his own hands he should be given Special attention... The rocker arm insert plates carry constant loads during movement, therefore they are rigidly fixed and tightened with screws and Grover washers. The fastening shackles should not be strongly compressed by the screws, allowing the hinge axis of the plate to move.

It is advisable to make the rocking rack from a single piece of material. A groove for the rocker arm is made on the upper side, a rectangular opening is cut out at the lower end for the second rocker arm. The post can be folded in two to make it easier to cut holes.

Design and specifications

The device of any model of jigsaw must contain:

saw;
crank assembly;
drive unit;
saw tensioner;
Desktop;
auxiliary mechanisms.

The larger the table, the longer the cut can be made. On average, this figure is 30 - 40 cm.

The drive power for a homemade benchtop machine is about 150 watts.

The crank assembly converts the rotary motion of the drive into reciprocating and transfers it to the saw. On average, the frequency of oscillation of the saw blade per minute is 800 - 1000. The amplitude of vertical movement is not more than 5 cm. Some models allow you to select the speed of movement depending on the properties of the material.

A hand jigsaw saw can work with wood, plastic, no more than 10 cm thick, having a length of up to 35 cm. For different types of materials and work, the files vary, their width is 2 - 10 mm.

A manual tensioning device secures the saw blade for even cutting, it consists of coil or spring springs.

Types of machines

Structurally, all jigsaw devices can be divided:

with lower support;
with double support;
on a suspension;
with a degree scale and stops;
universal.

Suspended machines are not equipped with a monolithic bed, they are very mobile. During processing, the cutting unit moves, not the material. The working module is usually attached to the ceiling by hand, so the size of the material is unlimited. The cutting tool moves by hand independently of the bed, creating highly complex patterns.

Machines with a degree scale and stops are good for precise drawing work. The design allows you to avoid errors. Universal jigsaw machines can perform several operations associated with cutting: drilling, polishing, grinding.

Making a machine with your own hands

Drawing of a homemade desktop jigsaw: 1 - rocking insert (2 pcs.), 2 - earring (2 pcs.), 3 - table, 4,6 - screws, 5 - pull rod, 7 - eccentric, 8 - base, 9 - axes of the earrings, 10 - upper rocker arm, 11 - rocker arm axis, 12 - lamb, 13 - tension screw cross member (2 pcs), 14 - tension screw, 15 - rocker arm, 16 - lower rocker arm, 17 - box, 18 - double-ribbed pulley, 19 - intermediate shaft, 20 - rack bushing, 21 - table plate, 22 - bearing with cover (2 pcs.), 23 - electric motor pulley.

Owners of a manual jigsaw are more fortunate. You can make a stand from a sheet of plywood and attach a jigsaw to it. To fix the jigsaw with your own hands, you will have to make holes in the base of the tool. The simplest model is ready.

To change the amplitude of movement of the rocker, four round through holes with threads are made on the eccentric flange, located at different distances from the axis. By changing the location of the screw, the swing of the rocking chair is adjusted. It consists of a pair of wooden rocker arms hinged to the rack. The rear ends of the rocker arms contain through cuts and tension screws are inserted into them. A file is fixed at the ends in front, movable due to metal hinges. Before fastening, the file is inserted into the groove of the working surface of the table.

The file attachment mechanism is very important. When making a homemade device with your own hands, you should pay special attention to it. The rocker arm insert plates carry constant loads during movement, therefore they are rigidly fixed and tightened with screws and Grover washers. The fastening shackles should not be strongly compressed by the screws, allowing the hinge axis of the plate to move.

A jigsaw is a special device that is designed to perform work on sawing wood, its derivatives, as well as other materials (for example: plastic, drywall sheets, foam and so on) along curved contours and straight lines.

Depending on the power electric drive can be conditionally divided into two types:

power up to 150 W;
power over 150 watts.

Machines with a power of up to 150 W are used mainly at home, for work on the manufacture of various crafts from materials of medium and low density and thickness.

Machines with a drive power of over 150W are mainly used in industrial environments, when working with hardwoods and other materials. Such jigsaw machines allow you to work with a material thickness of up to 10 centimeters.

For home and semi-professional use, in order to save money, you can make a homemade jigsaw. In this case, you will need basic knowledge in plumbing and electrical engineering, as well as a small amount of hand tools.

Making a homemade jigsaw machine

In order to make a jigsaw machine with your own hands, you will need:

eight wooden planks for making the frame;
a sheet of thick plywood for the countertop;
several metal corners, welding machine;
electric jigsaw;
accessories for fasteners, drill.

1) We start designing the machine with the frame. The frame will require wooden blocks square section 50 * 50 mm. For the support posts, four beams are used with a length of 250 mm.

For the longitudinal connecting beams, 380mm long bars are used. The end connecting beams are 250mm long. All the bars are connected to each other using ordinary wood screws.

2) We make a tabletop. For the countertop, we take plywood, in this situation one should be guided by the principle: the thicker the better. A sheet of plywood 10mm thick can be considered normal. The sheet is cut to fit the dimensions of the frame so that the edges and corners protrude 5 centimeters beyond the edge.

After that, the attachment points of the legs and the jigsaw itself should be marked on the plywood board. Holes are drilled according to the marking so that the self-tapping screw is in the center of the leg.

The attachment points should be transferred to the markings for the jigsaw and the holes drilled. Also, a hole for the saw blade is cut in advance. We fasten the tabletop to the frame with self-tapping screws.

3) The next step is to install the jigsaw under the countertop. For this, the entire structure of the rack is turned over onto the tabletop lid.

The electric jigsaw is installed according to the markings and bolted to the tabletop. At this stage, one must not forget that the canvas must already be installed and occupy the position provided for it with a margin of the hole.

At this stage, you will need a welding machine to manufacture the fixing structure. It will require four corners. Bottom bar 50 * 50mm with two bolt holes. A 200mm long corner is attached to it. Further, a corner of 230 mm in size (selected for each case individually, depending on the distance from the edge of the table top to the canvas).

The descent to the canvas is made from a 150 mm long corner, to which a jigsaw wheel is attached. This design absorbs all vibration from the web and prevents breakage. The entire structure is attached to the tabletop with two screws. They should not be weakened by vibration.

The work on the manufacture of the jigsaw is over, the machine is ready for full operation.
