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. The desktop electric model has gone quite far from its prototype, an ordinary manual jigsaw. 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 differ greater productivity. 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 slabs, figures with complex outlines from laminate and plasterboard, plastic blanks, also for cutting sheet metal.
The benchtop electric jigsaw makes clean cuts in complex shapes and works on small
details. Due to the stable and fixed position during operation, high cutting accuracy is achieved. 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 application, technical characteristics, type of power supply and design features. IN construction stores You can buy a desktop jigsaw to suit 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 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. Increased performance characteristics are inherent in lithium-ion batteries. The battery capacity is responsible for the duration of operation without recharging.
Advantages of desktop jigsaws
The tabletop electric jigsaw is stationary structure, therefore this cutting type The 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, ample opportunities settings depending on the material and the required part of the cut workpieces.
If you need to cut small parts, 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 the large size 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 Not large 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 into the plywood and base plate jigsaw.
Then you need to secure the jigsaw with screws to the plywood base so that the file can fit 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 ordinary, but there are possibilities for good sawing expand due to the freeing of hands.
You can use a nichrome spiral from any household heating device (iron, for example) as a heating filament. 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 of the 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 the force is too high, the cut material may be caught in 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 the needle will break at best, or you will ruin the work at worst.
- Replace saw blades from time to time. old saw can spoil 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 blades are required, with a special pitch 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.
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 structure also remains, and if greater strength of the holder is needed, it can be installed again, although new design remained 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 a utility 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.
An electric jigsaw is a type of equipment for wood processing. Currently, the choice is presented not only in the usual manual version, but also in the electric version. These models, for example, Vario 502 dks, Dremel have high performance, are quite easy to use, and come with a large number of removable components.
These devices can be used both at home and in production. Today, such a mechanism can be bought ready-made or made with your own hands, for example, from an old sewing machine.
1 Technology of use
The main working element of a manual jigsaw is small files, which usually have a length of 50 to 120 mm. It is driven by an existing electric motor and makes translational movements vertically during 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 base of the equipment. Such a fixation allows the worker to more easily operate the system and freely adjust the angle of the tool. Operator safety in this design is ensured by the presence of a special screen.
These models appeared on mass sale in last years. Previously they tried to make them for 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 jigsaws
TO strengths It is this technique that must be considered:
- Possibility of using the device for a wide range of woodworking thanks to a large number replaceable cloths.
- Greater reliability in use: due to the wide blade of such a mechanism, you can avoid breaking parts made of wood or tile during processing, as well as perform any complex contours with a minimum of effort.
- The ability to feed a piece of wood with both hands by attaching it to the blade. Previously, without such a device, working with samples manual type was much more complex.
- Ease of processing any kind of material – even relatively small ones the jigsaw can easily cope with wood 50 mm thick, not to mention more powerful models.
- Wide range of processing options.
Among the disadvantages of using such a device, the short stroke of the samples is usually noted, due to which the work with thick webs is significantly more complicated.
It is also impossible to make the bending radius as small as when using a manual sample (due to the peculiarities of fastening the file).
2 Scope of application of machines
Modern electric jigsaw machines are suitable for next works to choose from:
- Sawing complex contours from a sheet blank.
- Treatments inner surface workpiece without violating its contour integrity.
- Finishing of some samples.
A tabletop jigsaw machine is used primarily for processing wooden workpieces. It is most often used in furniture production, musical instruments. In recent years, they have also often begun to be used for the production of decorative items, as well as souvenirs.
2.1 Consumables
The main consumables that a tabletop jigsaw has are files, including spiral ones. They differ in length, size of teeth, distance between them and are selected for each material individually.
Usually, when setting up a jigsaw machine with your own hands and buying files for it, experts recommend choosing Supplies for the following features:
- To cut wood or plywood workpieces, choose saw blades with a pitch of 2-4 mm.
- Metal samples, as well as plastic, are usually processed by choosing 1-2 mm files, including spiral ones. Experts who provide reviews on the use of such components recommend choosing models with a wavy edge. The choice of these is very large.
- When working with tiles, use special saw blades with an abrasive coating.
You can select these elements for processing wood and other materials not only based on reviews, but also based on technical characteristics the equipment you have chosen.
After all, almost every machine has a list of consumables, including all the files suitable for it for certain products.
Also, do not forget about additional elements such a design, which, for example, in models Dewalt, Dremel, Holzstar, Vario 502 dks include a drilling unit and 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 your own hands, is presented on the market in huge quantities various products. Their choice is really wide, including 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 already possible to analyze the device according to all parameters. And then you can get the ideal component to perform any task. You can also assemble a tabletop jigsaw with your own hands using general recommendations for the production of such devices.
It will not be difficult to do this yourself using a sewing machine or other similar mechanism. The main thing is to study the design well, select the necessary components and do everything to make the model reliable.
2.3 Electric jigsaw machine Enkor Corvette-87 (video)
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 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 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 the typical tasks of a 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:
- With lower support.
- Double-support.
- On a pendant.
- With degree scale and stop.
- Universal.
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:
- A support table is made. 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 nearby.
- The factory device is fixed at the bottom of the support table. Holes for fasteners are made next to the hole for the saw blade. Countersunk head screws 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 caps of the wines, which will cause inconvenience in work.
- The structure is fixed on a wooden table.
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 manual option a tool that can be used on a homemade machine - it’s cheaper. 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 is the file - it is too wide manual models. Because of this delicate work It is difficult to do on wood 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:
- Build a rocker. The structure will be tensioned by springs on one side. The second side of the rocker is fixed to the file.
- Secure the file between two rollers. They serve as guides for the thin file.
- A stationary factory device is used as a drive for a system of two rocker arms. A file is pulled between the latter. The movement is transmitted from the factory device to the lower beam of the saw.
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. It will be more difficult to work with a manual drive because your legs will get tired. Additional disadvantage Vibrations from force on the tool will serve. 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 the version with a sewing machine, this will not be possible. If desired, markings are applied to the table to make it easier to measure parts during work.
Carving and sawing beautiful figures from wood - exciting 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 only be done on stationary machine, where the device for sawing in wood or plywood is firmly and securely fixed on 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 that does not require too much expense.
For this homemade design machine you will need:
About the construction of a table for stationary jigsaw 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, it is necessary to file the shank from the side so that it fits freely into the clamp. standard canvas from a factory electric jigsaw. 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. Removing it is easy with just 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 sewing machines They 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.
