I didn’t want to permanently place my expensive Makita jigsaw on the table, so I decided to buy another one to create a table. I was very lucky to find a jigsaw in the “Our House” store Caliber LEM-610E for only 862 rub. Includes: wood saw, side stop, adapter for vacuum cleaner, spare brushes for the motor.
There was an outlet next to the display case and I looked at it in action. It is quite well made, convenient, there is a speed control with a wheel, and the activation is fixed with a button. The saw holder moves smoothly without any play.
It’s very fortunate that I was able to twirl it in my hands before buying it; I wouldn’t risk ordering it from the Vseistrumenty.ru website without knowing what it is. (Although they write good reviews about it) By the way, it costs more there and there is also a delivery fee... so I successfully bought it at Our House. :)
Despite its advantages, it has a number of disadvantages that I noticed upon closer examination:
1) The file does not fit into the saw holder. Apparently this is a defective copy, but I did not waste my time on the exchange. Each file has to be sharpened. (Although I won’t be able to use them on the second jigsaw after grinding - it doesn’t matter, they are relatively inexpensive)
2) And this flaw is visible 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 heavily, not very clearly and with jamming. At the minimum speed value, the tool cannot start at all (However, the same garbage with starting is with my other “calibrated” 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 convenient to turn on with a standard button and lock into place.
To do this, I bought a bracket at KrepMarket (this is a fastening element from some kind of iron structure system)
By the way, I really love CrepeMarket. Any screws, nuts, screws, fasteners. Every time I design something, I wander around in thought and type the necessary details.
I cut off the excess and sharpened it.
Back view. Now the distance between the bearings has a fixed clearance for the file of 1.2mm. I have a plan for the future: to make a gap adjustment.
For thin materials it can be lowered.
As an experiment, I drew a star and tried to cut it out evenly
For a 130mm file, the maximum possible thickness is 5cm. It turns out there are very long files; I recently saw a 300mm file on the market
I sawed off a 1.5mm slice from a 40x40mm block
Which is what I did. Now you can use it to cut long workpieces 11.5 cm wide. The old L-shaped design also remains, and if greater strength of the holder is needed, it can be installed again, although the new design remains quite strong and reliable.
I also came up with the idea of making a knife from an old dull file, grinding off its teeth and sharpening it.

They can be used to cut material like sealant into shapes. The cut is smooth. Much better than stationery knife. The photo shows a mouse pad.
Well, that's probably all. The table turned out to be reliable and comfortable. Now I have a tool with which I can perform more delicate work than with a circular saw.
A tabletop jigsaw is an indispensable item for any owner who is used to doing household work on his own. Electric jigsaws are especially good for residents of the private sector, hobbyists manual labor and country holidays. From its prototype, an ordinary hand jigsaw, a tabletop electric model gone far enough. A desktop jigsaw makes it easier and faster to cut, not to mention improving quality.
Concept of a tabletop jigsaw
A jigsaw is a saw, which is characterized by reciprocating movements of the saw blade, which acts as a working body. It has a ski designed to guide the saw blade when moving along the surface that is being processed, and makes movements at a frequency of up to 3000 vibrations per minute.
This instrument was invented in 1946. Its creator is Albert Kaufman, who replaced the needle in a sewing machine with a blade. The instrument went on sale already in 1947. A manual jigsaw has a body with a flat platform and a handle. Main difference electric jigsaw from the manual one lies in its greater functionality and cutting quality.
Located inside Electrical engine and a special mechanism that drives the blade. In stationary jigsaws there is no handle, and the platform is located on top. At the front of the mechanism there is a guide, at the bottom there is a retractable blade that moves and makes cuts.
The tool works as follows: a tabletop jigsaw file is securely secured with clamps in the slide. The reciprocating movements have a frequency of up to 3000 strokes and can be adjusted. The support platform allows the jigsaw to focus on the part being cut, so the work is carried out very accurately.
The purpose of a desktop jigsaw
A jigsaw is an integral part of every workshop and every hobbyist. Its thin file can successfully cut plywood, copper, iron, thick boards, brass, and steel. Tools come with motor, foot or manual drive and are more productive. An electric jigsaw is simply indispensable for carpenters, wood workers, furniture decorators, and drywall workers who produce complex parts.
An electric jigsaw can make straight and curved cuts on workpieces with complex shapes and various sheet materials without disturbing the external contour. Most often, tabletop jigsaws are used for cutting wood and wooden boards, figures with complex outlines made of laminate and plasterboard, plastic blanks, and also for cutting sheet metal.
Benchtop electric jigsaw makes clean cuts complex shape and works with small
details. Due to the stable and fixed position during operation, it is achieved high accuracy cutting The file has a stable motion thanks to the tension system and guides, which manual jigsaws lack. The large size of the table makes it stable, so the precise sawing direction is maintained.
Types of jigsaws
Today, the power tool market offers a wide variety of jigsaws, which differ in the nature of their application, technical specifications, type of power supply and design features. IN construction stores can buy table jigsaw for every taste and budget.
It is difficult to classify by design features, because each manufacturing company strives to provide its products with features that are designed to facilitate and improve the operation of the tool. In this regard, the shape of the handle is a significant parameter.
There are two established types of handles - mushroom-shaped and D-shaped. A jigsaw with a staple handle requires one-handed operation. This increases the possibilities of using a jigsaw, but has a somewhat negative effect on the quality of cutting the material.
Mushroom-shaped handles allow for more accurate cuts when holding the jigsaw with both hands, having previously secured the workpiece to be cut. The choice of a jigsaw with a specific handle shape depends on the financial capabilities and personal preferences of the buyer. You should choose the jigsaw that will be more convenient to work with.
Household jigsaws are not intended for intensive use, but the low price of a desktop jigsaw and the power that is enough for household needs, make them indispensable in the household.
Professional jigsaws are characterized by high wear resistance and the possibility of daily long-term (up to 8 hours) use. The significant power of such jigsaws allows processing of materials of large thickness. Expanded equipment and improved characteristics are reflected in the price.
Among professional jigsaws, industrial jigsaws also stand out, which are characterized by greater adaptability to complex operations and drive features - for example, increased power supply voltage. Industrial models are machines that are designed for the woodworking industry.
Depending on the type of power supply, there are mains and cordless jigsaws. Network models are powered from a power supply network with standard voltage. If productivity is important to you, then you should choose a corded power tool.
Cordless jigsaws provide independence from the presence of sockets and greater mobility during operation. When purchasing a battery model, you should pay attention to the type of battery. Elevated performance characteristics inherent in lithium-ion batteries. The battery capacity is responsible for the duration of operation without recharging.
Advantages of desktop jigsaws
A tabletop electric jigsaw is a stationary design, so this type of cutting tool has many advantages. Modern models can work with wooden materials 40-50 millimeters thick. The working body is a narrow saw, which makes vertical translational and reciprocal movements. Due to the peculiarities of the notching of the teeth and the mechanics of the movements of the saw, the material is cut out by moving upward.
A tabletop jigsaw allows you to cut out complex decorative parts, make longitudinal, straight, inclined and transverse cuts. The wide tabletop allows you to process large parts and make cuts inside wide workpieces. Reliable fastening protects the housing from unnecessary vibrations and allows the material to be well positioned, so the motor can operate without overload.
The advantages of desktop jigsaws include good accuracy and clarity of cuts, high safety and ease of use, wide customization options depending on the material and the required detail of the cut workpieces.
If you need to cut out parts small size, a manual jigsaw will not be very convenient. It is quite heavy, so you will have to hold it with one hand and guide the workpiece with the other. A table jigsaw devoid of this disadvantage. Perhaps the inconveniences are too big sizes and the difficulty of working with large parts.
A tabletop jigsaw is a kind of mini-machine for cutting workpieces. If you purchase a jigsaw in a store, most likely it will provide the ability to select power and adjust the frequency of saw strokes. However, you can make a simple homemade tabletop jigsaw, and very quickly. You will need a hand jigsaw, a few screws, a piece of plywood small sizes and only an hour of work.
Making a tabletop jigsaw
A carefully made jigsaw will be little inferior to one made in a factory, and in some respects even superior to it. Assembling such a jigsaw is not difficult if you have necessary materials. Next we will describe simple diagram such manipulations.
The design of the jigsaw includes the following components: handle, switch button, insulating washer, power cord, frame, heating filament, screw clamp and earring. First you need to make a frame. You will need a duralumin pipe with an outer diameter of up to twelve millimeters.
You can also use textolite with a thickness of at least ten millimeters or thick plywood for the base. But keep in mind that the lighter the frame, the more convenient the jigsaw will be to use. Be sure to provide a channel so that you can lay the power cord later. Most best shape a frame is one whose sides are tilted 45 degrees.
Next you need to make an earring. It is made of copper sheet one millimeter thick. After this, it is attached with screws to the frame where it connects to the handle. In this way, the screw, wing nut and shackle will form a clamp in which the heating filament can be fixed. The thickness of the duralumin sheet should be up to 0.8 millimeters. It is necessary to make pressing cheeks from it, between which there is a switch button.
After this, you need to cut a gap in the plywood that the saw can fit through. It can be done using a drill. To do this, you need to drill holes along the marking line and smooth out the transitions. Instead of plywood, you can use plastic, metal, plexiglass and others. Next, you place and drill mounting holes on the plywood and jigsaw base plate.
Then you need to secure the jigsaw with screws to plywood base so that the file can pass through the gap. You attach the structure to the table using a clamp so that the file is pointing upward. You can also secure the platform in any way possible.
The jigsaw file remains a regular one, but the possibilities for good cutting are expanded by freeing up your hands.
You can use a nichrome spiral from any household heating device(iron for example) as a heating thread. It must be secured with tension between the ends of the frame bends. In order for the thread to heat up, you need to apply a tension of about 14 V. To control the operating mode, you can use a rheostat.
The current is determined by the thickness and length nichrome thread. Using a rheostat, you can set the optimal current strength (no more than 3-5 A), which will affect the temperature to which the filament is heated. Before starting work, it is necessary to determine the current strength. But keep in mind that if too high strength The material being cut can be caught by the flame, but if it is insufficient, it will not be taken. A self-made desktop jigsaw will allow you to cut out shapes with complex contours from various types materials.
Rules for using a desktop jigsaw
When working with a table jigsaw, you must adhere to some rules:
- When cutting, do not press too hard on the tool, otherwise it will best case scenario the needle will break, at worst, you will ruin the work.
- Replace saw blades from time to time. An old saw can damage and destroy the surface of the material.
- If you work with organic glass and non-ferrous alloys, the surface of the product must be moistened with water. This operation will speed up the process and extend the life of the saw.
- If you are cutting a surface with a thickness of less than one millimeter, place a sheet of wood or plywood under the material being processed.
- Before cutting, it is necessary to secure the material. It is better not to make long cuts by hand; the line may turn out to be crooked.
- For cutting different materials appropriate canvases are required, with special step and length.
- Rotate the tool by turning only the back of the tool.
- When cutting laminate, tape is applied to the cut line, which protects the material from chipping.
- If there is a need for curved cuts, set the jigsaw pendulum to minimum.
If you have not yet fully understood how to make a tabletop jigsaw, watch a video about this procedure. This tool allows you to cut complex parts from wood and other materials, make longitudinal, inclined, straight and transverse cuts. Using a jigsaw, you can process large parts, wide workpieces and small products, which is not superfluous at home.
Carving and sawing beautiful figures from wood is a fascinating activity. A person’s inclination towards this creativity manifests itself from early childhood and often remains throughout life. Everyone knows that this is difficult and rather painstaking work. It always requires not only special care, but also a lot of time. To eliminate this drawback and make your work easier, you need to automate the process. To do this, you just need to purchase a jigsaw in the store. However, such a device is not cheap on sale and not everyone can afford it. But this problem is easy to solve if you make a device for sawing and carving wood yourself.
For this you will need materials:
- drawings or diagrams;
- wooden blocks;
- short boards;
- pieces of old plywood;
- simple nails or screws.
Tools:
- medium sized hammer;
- regular hand saw;
- small plane;
- jigsaw;
- sharp axe.
Scheme or drawing
Before you begin assembly, you need to draw a diagram or make a drawing of the jigsaw yourself. With their own hands, rarely does anyone manage to complete a high-quality document on a good professional level, but it doesn't matter. You can always find a suitable drawing on the Internet and use it to assemble your jigsaw. Often for simple homemade device inventors use only a mini-circuit, simply drawn by hand. This is quite sufficient when you need to construct a simple device for figure sawing from plywood and wood.
Stationary option
There are often times when it is necessary to make perfect cuts in plywood or wood strictly vertically. This kind of work is simply impossible to do even with a factory jigsaw. A device that is always in your hand will produce deviations, and the edges of the slots will never be perfectly shaped. To make them straight and even, such work should be done only on a stationary machine, where the device for sawing in wood or plywood is firmly and securely fixed to the table surface.
To design a stationary jigsaw for figured cutting on plywood and wood, you must first prepare the material for building the table. It will provide a strong support for the machine and will also provide ease of use. All this is easy to make from wood. First you need to find suitable bars, mark them and make a table frame from them. After this, cut off identical boards, lay them on top and secure them with ordinary nails or screws. To ensure that the surface is sufficiently smooth, it is advisable to lay plywood on the table. It will not only make the surface smooth, but also create additional rigidity.
Next, you will need to install the unit itself for figure sawing from wooden blanks. Of course, you can make the entire mechanism out of plywood, but it will take too much time. The easiest way is to use a very simple method, where a standard factory device is installed to operate the saw - a jigsaw. To do this, you only need four small corners and a few screws. And then everything is done very simply: find the center of the table and drill hand drill hole through. Its diameter should be such that the factory file of a standard electric jigsaw can fit through it freely.
When a file is inserted into this hole and the entire device lies tightly on the table, you will need to draw a pencil around the duralumin support. Then use a jigsaw to cut a hole so that the body itself fits through it upside down, and its support bar sits tightly at table level. All that remains is to place small corners at the bottom and secure the platform with screws. At this point, the stationary jigsaw machine is considered built and you can safely begin work.
Sewing machine equipment
Today, many inventors successfully use modern methods, which differ good quality and precision in work. Particularly notable is the jigsaw machine using a band blade. However, despite the very high speed, not everyone can do it. For this reason, it is worth choosing a simpler method using an outdated sewing machine. Although her device has already served its useful life, it still needs to work homemade machine it won't affect. In addition, this is a fairly common and inexpensive option, where too much expense is not required.
For this homemade design machine you will need:
The construction of a table for a stationary jigsaw was discussed above, so we will not consider it further. But it is worth noting that a workbench can be perfect for these purposes. In addition, many old sewing machines already have a table-like design, as well as a mechanical drive. Therefore, here we will analyze only the main mechanisms that need to be changed.
Rework
Converting an old sewing machine into a tabletop jigsaw is not too difficult. First you will need to change the rear mechanical part where the needle is secured. To do this, you need to file the shank on the side so that a standard blade from a factory electric jigsaw fits freely into the clamp. The hole in the bottom plate, which is intended for the needle, also needs to be enlarged. This is easy to do with a hand drill with a diameter slightly wider than the file.
Often the clamping foot on a sewing machine gets in the way when cutting thick plywood or wooden blocks. It is easy to remove by unscrewing the side locking bolt with your hands or a screwdriver. As the jigsaw works, sawdust will remain. They are easy to assemble if you place a small box underneath. But before that, you have to remove the shuttle along with the entire device that will interfere. It is not difficult to remove it with only a small adjustable wrench or pliers.
Mechanical drive and motor
It is clear that turning such a machine by hand will be very difficult and inconvenient. Therefore, it is necessary to install an additional motor with a mechanical drive. Literally all samples of sewing machines have a pulley in their design. A motor is connected to it using a belt, which is turned on with your foot. If such a unit is not available, then it is not difficult to make it yourself. To do this, you just need to find an electric motor of suitable power. And then firmly attach it to the table using simple clamps - and you can actively get to work.
A jigsaw is a tool without which it is now simply impossible to perform many works on processing wood and materials in which it is used. Being compact and light weight, a hand-held portable jigsaw is capable of cutting out products of very complex geometry from a workpiece.
The jigsaw is very convenient to use and also provides very precise and thin cut. If you don’t want to spend money on a purchased jigsaw, you can make your own at home.
The lightest product
The jigsaw table itself can be made with your own hands in a short period of an hour. The advantage of the manufactured design will be its simplicity. It can easily be mounted on a tabletop or workbench and, if necessary, can also be easily disassembled. The disadvantage of a homemade design can be considered its small area.
The simplest product consists of the following parts:
- Plywood.
- Mounting screws.
- Clamps.
The working basis of the machine can be laminated plywood, in which it is necessary to drill holes for installing fasteners and for the saw itself. Plywood must be at least 10 millimeters thick. At the same time, you may also have to make holes in the base of your power tool for mounting screws.
A homemade structure can be attached to the workbench using clamps. Please note that the heads of the screws for fastening must be recessed into the surface of the sheet so that they do not interfere with you while working. Such a machine can easily handle the processing of small workpieces up to 30 millimeters thick. You can easily find a drawing of this type of machine on the Internet, and then assemble it yourself at home.
Another variant
This option consists of the following parts:
- Bed made of chipboard.
- Tube for vacuum cleaner.
- Laminated plywood for the machine cover.
- Confirmants.
There is a second option for a stationary device for working with wood material, which is collected from more spare parts, but making it will not be difficult. The frame is made of chipboard and consists of a back wall and two sidewalls. To make it easy to get to the power button, the machine has no front wall.
IN back wall do it yourself drill holes for the vacuum cleaner tube and cord. The cover for the machine can be made from laminated plywood 10 millimeters thick. The entire structure can be tightened with confirmants. The jigsaw can be secured in the same way as described above in the first case.
On a machine made according to this option, it is possible to process more massive workpieces, however, when working with a thick workpiece, the jigsaw saw can go in both directions and lean back. At the same time, cutting accuracy deteriorates. This drawback can easily be eliminated with your own hands by installing a bracket on a homemade machine that will serve as a support.
The jigsaw blade will move between two 11mm bearings, which must be screwed to an L-shaped strip made of steel. The back of the saw will rest against the wall of the bracket itself. This design will prevent your jigsaw blade from deviating from the intended path.
The bracket must be attached to the frame, made of 50 by 50 millimeter bars. It can be lowered or raised depending on the length and thickness of the wood being processed. To do this, the frame itself, together with the stop, must not be firmly attached to the side of the machine, but pressed against it with a hardboard, steel or textolite plate. We install a vertical frame post between the hardboard and the frame.
The machine can be more convenient if you mount an additional limit bar on it, with which you can cut the material into workpieces of the same length and thickness.
The limiter is attached to the machine using clamps. His made from wooden beam , aluminum or steel corner. For convenience, you can also install a bar on the slide, which must be secured to the sides or bottom of the tabletop.
Table for a jigsaw made of chipboard
To make this jigsaw table, you must have a certain carpentry skill, since when connecting its frame to the legs, it must be made into a tongue and groove. The tongue and groove itself can be replaced with a connection using dowels, wood glue and self-tapping screws.
The machine cover must be made liftable to facilitate access to the tool when replacing it. In order for the machine to be multifunctional, it is necessary to provide space for mounting a manual milling machine.
The table is assembled from the following materials:
- block 80 by 80 millimeters;
- block 40 by 80 millimeters;
- laminated plywood or chipboard measuring 900 by 900 millimeters.
Measure the distance between the legs, it should be from 60 to 70 centimeters. The bars for the legs and drawers will be obtained if you cut the bars 80 by 80 millimeters lengthwise. You can choose the height of the legs themselves at your own discretion, it all depends on how comfortable it will be for you to perform work on the machine.
At each end of the legs and drawers, it is necessary to drill two holes for dowels. The same holes must be made on the sides of the legs. Coat the dowels with glue half their length and insert them into the ends. After this, assemble the entire frame. It will turn out to be non-separable. After checking and possible corrections, it is tightened tightly.
All surfaces at contact points must be coat with glue. Use self-tapping screws for additional structural strength, which must be screwed through holes prepared in advance for them.
The cover must be attached to one of the drawers using hinges; to do this, a slot must be made in it to facilitate removal and installation of the jigsaw. In the back of the tabletop, you need to screw two strips with a pre-selected quarter into which the sole of the power tool should fit.
Holes must be made in the strips, into which bolts or clamping screws must then be installed. A jigsaw mounted under the tabletop will be able to cut thicker material if a recess is made in the lid for its sole. The easiest way to make this deepening is using a milling machine.
The resulting table will be very simple and spacious, so the necessary strength of its lid can be provided by a large thickness of chipboard or plywood. Use sheets of 20 millimeters or thicker.
Jigsaw using thin saws
Since when cutting complex patterns in plywood, a jigsaw is not well suited for this, you need to take a thin file. It can be fitted to hand power tool, using the original device.
We also attach the jigsaw to the tabletop, but the thin file needs to be tensioned, since it will not be enough just set on a pendulum. To facilitate the process of tensioning the file, it is necessary to make a rocker arm from a block.
The tension of your canvas is ensured by a spring. Place its lower loop on the transverse pin. The upper loop must be inserted into the adjusting screw, which changes the tension force of the damper. All wooden blanks for a homemade machine, they are made of hard wood.
Since there is no possibility of attaching a blade in a jigsaw thin section, you can remake the fragment old saw, having previously drilled a hole in it and completed it with a screw with nut and clamping plate.
A vertical slot must be made in the rocker arm into which a second steel plate must be inserted. It is attached to the rocker with screws. The upper part of the file must be attached to it in the same way as the lower one. To make it easier for you, you can use scraps from an old jigsaw to make the plates.
The desktop jigsaw machine is designed for cutting out various parts with complex configurations from sheet materials. This tool can work with MDF, chipboard, fiberboard and many others. Jigsaws can also cut out internal contours parts if you first make a small hole. This tool has a wide range of applications, since it can provide high performance labor, which cannot be achieved with a regular hacksaw.
Design features
The design diagrams of all jigsaw machines are usually the same. Having carefully examined the drawings where this tool is depicted, you can see the following structural components:
- the bed, which is also often called the body. It is designed to accommodate everyone structural elements unit;
- drive mechanism;
- crank mechanism. It is necessary to convert the rotational energy of the motor shaft into the movements of the saw used during operation;
- double rocker arm. Equipped with fasteners for a file and a tension device;
- Desktop. In some modern models it has a rotation mechanism that moves at a given angle.
How to make a machine from a jigsaw?
To make a jigsaw from a manual jigsaw, you need to follow these instructions:
- First you need to make a table where a homemade jigsaw will be installed in the future. For this purpose use any durable sheet material– thick plywood, metal and others.
- They do it in the table through holes, designed for cutting blades and various fasteners.
- Received jigsaw table set and securely fasten on a suitable wooden table.
- The resulting table is equipped with guide rails.
- Fixed at the bottom manual jigsaw, which allows you to replace the drive mechanism of the machine and many of its other structural elements.
Anyone can make such a jigsaw machine with their own hands. Its advantage is that at any time this unit can be quickly disassembled and only hand tools can be used.
Homemade jigsaw table-machine from a manual jigsaw
How to make a more professional instrument?
A homemade jigsaw machine can have all the qualities that are present in professional equipment. To make it you need to follow these instructions:
- The frame is made from any durable material - 12 mm plywood, plastic, textolite and others. It should consist of a base, a housing to accommodate all structural units and a work table.
- On the other side, a rocking chair with an eccentric is placed. They need to be connected to each other using metal plates with sleeve type bearings. The resulting structure is installed using screws.
- The intermediate shaft is formed from several bearings.
- The metal pulley is placed very tightly on the shaft and the screw connection is secured.
- To change the movement characteristics of the rocker, 4 holes are made on the eccentric flange round shape threaded. They should be placed at different distances from the center line. The amplitude of movement of the rocking chair is regulated by the location of the screws.
- The rocking chair is formed from wooden rocker arms, which are attached on a hinge to the stand.
- Small cuts are made at the rear ends of the rocker arms. They are designed to install tension screws.
- The front ends of the rocker arm are designed for mounting a saw blade. It moves using special metal hinges. Before attaching the file, it is installed in a groove located on the work table.
- The rocking stand is made from a single piece of durable material. A groove is made at its upper end for installing the rocker arm, and a small hole is cut out near the lower end rectangular shape for mounting the second rocker arm.
How to make a machine from a sewing machine?
A sewing machine makes an excellent jigsaw, which is equipped with a saw blade movement regulator. It is not difficult to do if you follow these instructions:
- The thread weaving mechanism is removed from the bottom of the machine. On some models it may be located in a different location.
- To dismantle this unit, you need to remove several bolts, then remove the cotter pin and drive shaft.
- The top protective panel is unscrewed. After this, the groove along which the sewing needle moves must be expanded to suit the parameters of the file.
- The cutting element itself is also slightly modified. It is trimmed according to the length of the sewing needle.
- Making an adapter for installation cutting element not necessary. Instead, you can grind down the upper incisors a little and process the lower zone of the blade.
- The file is inserted into the needle holder and work begins.
All presented options for manufacturing jigsaw machines are very successful. The resulting units are distinguished by high labor productivity, and making them is not at all difficult. Depending on their skills, each master will be able to choose best model homemade equipment.
