For figured cutting on wood, a hand jigsaw was traditionally used - a simple tool with a thin file that allows you to create elegant patterns from wood. Later, a jigsaw machine was invented, working on muscular traction, like a foot-operated sewing machine or a potter's wheel.
The development of technology and the emergence of compact low-power electric motors led to the creation of a manual jigsaw, and then a corresponding electrified machine, which you can make yourself.
Purpose
Stationary units that ensure vertical movement of the saw make it possible to cut parts of complex shapes and elements with curved edges from sheet materials. If you insert a file into a through hole drilled in the workpiece, you can make a shaped contour inside the product.
Using jigsaw machines, workpieces from various sheet materials are processed, including:
- solid wood;
- plywood;
- wood-containing boards (chipboard, fiberboard, MDF);
- aluminum;
- plastic.
Using a jigsaw machine you will be able to increase labor productivity and significantly improve the quality of processing of shaped edges of products. This is explained by the fact that the working person has both hands free and can position the workpiece as accurately as possible relative to the moving cutting blade. This is the main advantage of a stationary tool with an electric drive from a manual jigsaw.
Jigsaw machines are installed in school and home workshops; this type of equipment is also used in furniture production and in the manufacture of musical instruments. Modern laser machines can be used instead of jigsaws, since they provide the highest cutting accuracy along a given contour, but their use is limited by the effect of burnt ends of parts.
Device
The tabletop jigsaw machine consists of the following elements:
- bed (supporting structure on which all mechanisms and components are mounted);
- Desktop;
- electric drive;
- crank mechanism (responsible for converting the rotation of the engine shaft into reciprocating movement of the saw);
- double rocker (equipped with clamps for saw blades and a tension mechanism).
The machines produced today are mostly designed to use saw blades with a length of 200-350 mm and a working stroke of 30-50 mm. Files vary in width (2-10 mm), thickness (0.6-1.25 mm) and type of shank - they come with pins and without pins. The latter are more convenient, since to cut out the internal contour it is necessary to drill a hole in the workpiece through which the end of the file should pass. If there is a pin, the hole should be noticeably larger. Some models of jigsaw machines allow you to attach both types of files, including old-style ones, from Soviet hand tools. Files also vary in the size of the teeth and their arrangement - it can be straight or spiral.
Tool selection
To choose a good machine suitable for solving specific problems, you need to pay attention to its power. The majority of models are equipped with an electric drive with a power of 90 to 500 W. For home use, the optimal power is 150-200 W.
An important selection criterion is the presence of two operating speeds of the unit. In the standard version - 600 and 1000 rpm. This makes it possible to select the appropriate mode for working with materials of different densities.
The desktop can be fixed or rotating. Fixing the table at an angle allows you to cut material at specified angles other than 90°. There are also models that provide table height adjustment - this allows you to extend the service life of the file, since you can use different sections along its entire length for work, and not just the central part.
Manufacturers equip jigsaw machines with a variety of options, including:
- a compressor to remove chips from the marking line with a stream of air;
- drilling block;
- illumination of the work area;
- guarding the blade (will not allow your fingers to come into contact with the moving saw);
- clamping device (prevents vibration of sheet material of small thickness).
Additional options increase the cost of the jigsaw, but do not fundamentally affect its functionality.
Manufacturers
There are various types of jigsaw machines on the power tools market: from devices designed for creative work at home to high-performance models designed for professional use. In addition to machines that use regular saws, you can find band jigsaws on sale.
The list of popular brands includes Bosch, Hegner, Einhell, Proxxon, Makita, DeWALT, JET, Xendoll, Excalibur, Kroton, Korvet, Zubr.
The leaders in quality and reliability are the products of famous German brands Bosch, Einhell and Hegner. In addition, the lines of jigsaw machines include a wide range of models of varying power and configuration, which makes it possible to choose a high-quality electric jigsaw for the home that is optimal in functionality.
Budget models, including those made in China, have also performed well. Models of the Korvet, Zubr and other brands are suitable for home use without increased loads.
Before purchasing a jigsaw machine, regardless of its brand, you should definitely conduct tests to evaluate the smoothness of the working part and the noise level, and make sure there are no extraneous sounds and vibrations. It is recommended to compare several models from different brands and purchase the option with the best performance.
Making a jigsaw with your own hands
A homemade machine, made to replace a conventional jigsaw for wood, is capable of ensuring high-quality performance of the basic set of operations for shaped cutting of sheet materials. Depending on the purpose, you can design a compact electric model or a stationary unit designed for high loads.
Materials
As a basic diagram, it is most convenient to use a drawing of a simple wooden jigsaw with a flywheel and pedal assembly and replace the mechanical drive with an electric one. If the machine is intended to be used only occasionally, you can do without a special electric motor. Instead, connect any suitable power tool. It is convenient to use a screwdriver with adjustable rotation speed.
The material used to manufacture the machine itself is wood, and:
- it is better to make the frame and the supporting pedestal for the lever bar from high-strength plywood (minimum thickness - 18 mm);
- for a lever structure, you need to take dense wood that is not prone to cracking under load - beech or oak (instead of buying bars, you can use straight legs of old chairs of suitable size);
- for the crank mechanism, plywood with a thickness of 10-12 mm is required;
- For the remaining elements of the structure, pine lumber and various trimmings are suitable.
According to the jigsaw machine diagram, a bed and a supporting pedestal are made. Wood screws should be used as fastening elements; it is recommended to coat the joints of wooden structural elements with PVA emulsion. It is important that the structure is strong and there is no play, otherwise the accuracy of the machine will be low.
Parts preparation and assembly
Next, the levers of the required length are cut out, and cuts are made at their ends for fastening the saw. The mount is made of a steel plate 2-3 mm thick, with a pair of holes. The upper hole allows you to fix the plate on the lever, and the lower one is intended for attaching the shank of the file. Fastening elements - screws of suitable diameter and nuts - are more convenient to use wing nuts. The mount is installed on the lower arm in the same way.
At the next stage, the lever system is mounted on the frame. To connect the free ends of the levers, a screw tie (lanyard) is used, which makes it possible to easily adjust the tension of the saw blade.
Note! The length of the files used should be determined in advance, since the size of the lever mechanism depends on this. It is necessary to ensure that the levers are as parallel as possible relative to each other.
The racks need to be fastened together to create a strong support for the flywheel. The axis can be a pin or a bolt of at least strength class 8. The flywheel is connected to the lower lever by means of a connecting rod made of the same plywood, while the rods connecting to the lever must be metal.
At the next stage, a work table with a rotating mechanism is made - a rotating arc with a slot must be cut out of plywood. The table is installed on the bed. To easily fix the rotating mechanism in the desired position, use a wing nut.
In this model, the electric drive is a screwdriver - to operate it, just connect its chuck to the flywheel axis. You can regulate the speed using a variable-force clamp made of a durable strap and a small clamp (or other screw tightening).
The homemade machine, simple in design, is easy to use.
Robust stationary design
The design of a jigsaw for professional use is practically no different from a compact wooden model. It is only important to choose the right materials so that the unit is able to withstand increased loads and does not vibrate during operation.
- bed – heavy chipboard;
- stand for a lever structure - hardboard, textolite of suitable thickness;
- levers – steel square pipe;
- table top - any durable, hard and smooth material.
Elements for fastening the blade (can be taken from an old hacksaw) are soldered to the levers or secured with screws.
You will need a working electric drive with a gearbox that will provide the necessary torque. To start the engine of a homemade jigsaw machine, it is convenient to provide a foot pedal (taken from an old electric sewing machine or made using any suitable electric button).
When assembling the structure, metal stands and metal fasteners are used. Using a metal insert, you can strengthen the fastening of the connecting rod. This will reduce vibrations and reduce wear.
The tabletop has a long working slot to allow rotation around the longitudinal axis.
A spring is provided to tension the web. The lower lever is responsible for the movement of the working blade, the upper one helps to hold the file in a vertical position.
Thus, an electric jigsaw can be assembled on your own using available materials. This will not require serious financial costs, but will only take some time to find materials, necessary parts and assembly.
What if you need to use a jigsaw, but have no desire to purchase one? Experienced craftsmen will answer that in this case the easiest way is to make a jigsaw with your own hands.
There are multiple ways to make and repair such a tool yourself. Below is a list of options for using the simplest and most accessible of them.
Making a manual jigsaw using simple technology
Before making a jigsaw, you should prepare inexpensive and accessible materials. Let's present them in the form of a list:
- sheet plywood - 12 mm;
- sheet plywood - 5 mm;
- sheet steel - 2 mm;
- set of bolts and nuts;
- drill (manual or electric);
- chisel;
- sanding paper;
- files.
As a base for a manual jigsaw, you must use a bracket, which is made from a sheet of plywood (12 mm).
After this, you should thicken the handle using a thinner plywood sheet (5 mm). This thickening is glued evenly on both sides of the handle, which ensures its comfortable position in the hand during subsequent work with a jigsaw. At the same time, the bracket and handle must be carefully processed using sandpaper and files of different classes.
The steel plate must be cut out using a chisel and the clamping jaws must be cleaned using a file. Next, you will need a drill to make slits in the jaws. Having taken this step, we begin to cut out notches on them with a sharp chisel. The left clamping jaw must be modified in such a way that a threaded hole is made for the bolt. We attach the jaws to the bracket, and then screw in the bolts on the left clamp, securely securing it with a nut.
Options for making a tabletop jigsaw
Desktop devices of this type can be made either from scratch or by modifying existing devices.
Option 1
To make a new benchtop mechanical jigsaw, you must first acquire the following tools and consumables:
- duralumin pipe;
- plastic base;
- screws;
- copper sheet;
- drill.
First, we prepare the frame; a duralumin pipe is well suited for this purpose. During the manufacturing process of the frame, a passage must be provided through which an electrical wire is laid, which will provide the tool with power. Using a copper sheet, a U-shaped frame is made, which is then attached directly to the frame. In the area where the frame connects to the jigsaw handle, the frame is screwed in with screws.
Then we take a plastic base to drill holes and mounting slots in it. We fix the jigsaw on the prepared base so that the file can pass freely through the hole. Using clamps, we attach the finished device to a flat surface, for example, to a table.
Option 2
To make a jigsaw, you can use a sewing machine, the repair of which is not necessary. To make such a tool you will need the following materials and tools:
- foot or manual sewing machine model;
- hacksaw blade;
- needle file;
- electric drill.
We unscrew all the bolted fasteners from the lower parts of the machine structure, and the entire working system with thread is completely removed. We remove the metal fastening rod by knocking it out and remove the drive shaft. We unscrew 2 more bolts and disassemble the panel that covers the sewing machine; removing it is quite simple. Using gentle movements, remove the sewing needle and get to work.
First of all, we carry out work with the slot for the needle. We expand it to such a size that the file can fit there. A needle file will help you cope with this task. It should be selected based on the size of the hacksaw blade. Try to adjust the size of the slot for the file as accurately as possible. Having bored out the connector, you can install the blade in place of the former needle holder. And finally, when turning the wheel, you need to check a few things to:
- there was no contact between the saw, the panel and the presser foot;
- there was free passage of plywood under the saw in the upper position;
- the materials were drawn in a smooth motion without jerking.
These jigsaws are suitable for use with plywood, balsa wood and plastic, and when using an electric machine, such a device can be converted into a jigsaw.
Video “Jigsaw. Choosing a tool and working with it"
If it is not possible to repair the jigsaw
If using a manual jigsaw is not up to the task, and electric jigsaws cannot be repaired, then you should use the options presented below that will allow you to make a jigsaw. Electric jigsaw table type:
- electric jigsaw for manual use;
- sheet plywood;
- set of clamps;
- 10 pieces of screws;
- electric drill.
We make markings for the slots in the plywood and carefully cut them out. If there is a pendulum stroke, it must be turned off. Then we place a hacksaw blade in the slot and attach it there. We also make several slits on the plywood by drilling holes with a drill and connecting them to each other. Screws are placed in the slots made. As a result, securing the tool with clamps on flat surfaces will not be difficult. The device is ready.
Jigsaw from an electric drill:
- steel sheet (4 mm);
- steel sheet (1.5 mm);
- steel sheet (1 mm);
- steel rail (2 mm);
- spring rail (0.9 mm);
- steel rod (7 mm cross-section);
- electric drill.
Using sheet steel (4 mm), we make a product in the form of a C-shaped frame, which will be the base of the jigsaw. Next, attach it to an electric drill. For this purpose, it is necessary to create a special clamp from a steel sheet (1.5 mm), which will ensure fastening. We attach spring slats to the edges of the base. We will need a steel sheet (1 mm) to make clamps with which the saw will be attached. Clips like these on the edges will also help strengthen the C-frame. And from a steel rod you can make a crank that will power the saw. For the connecting rod we need a steel strip, which will allow us to create a crank mechanism.
At this point, the work on making the jigsaw can be considered complete. Due to its massive size, for safety reasons it is better to clamp the drill in a vice while working. And it’s best to place working materials on flat surfaces.
Video “Jigsaw. Modernization"
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 a rotary table, which makes working with the part easier and improves visibility. 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.
The designs and drawings of the homemade jigsaw options presented online 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. The factory manual device is a 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 a manual version of the tool that can be used on a homemade machine - it’s cheaper. Stationary devices are expensive.
Comfortable work with wooden products can be ensured 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 in manual models. Because of this, fine woodwork is difficult to perform with it - the curvature of the lines is limited.
The previous design is simple and does not have additional parts that make working with wood easier. The direction of modernization is the possibility of replacing the file with a thin one.
Options for improving the design:
- 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.
When buying or making it yourself, you have to choose a design based on personal preferences and the 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 curly cutting on plywood is ready. It will be more difficult to work with a manual drive because your legs will get tired. An additional disadvantage will be vibrations from force on the tool. The electric drive of the machine, converted into a jigsaw, partially solves the problem of vibrations.
An expensive jigsaw can be replaced with a homemade design. 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.
Many people have known the fun of cutting with a jigsaw since childhood. The technology is simple. But despite the apparent ease and simplicity of the work, you can get very beautiful lace from wood or plastic. This is a very slow process that requires persistence and patience. To make work easier, jigsaw machines were developed. They are functionally divided into two groups: with manual and electric drive.
Jigsaw device with muscle drive
A homemade machine is easy to make. You can find many drawings of this plywood product. Using a jigsaw, your own hands and improvised tools, a simple but functional device is assembled in a short time.
The scope of application of jigsaws is extensive. They are used for cutting figured products from a variety of materials. Machines are also necessary for cutting lumber. In this case, the outer contour of the workpiece remains intact. If you use various files, a homemade jigsaw will perfectly process natural wood, plywood, chipboard, plastic, metal, in particular aluminum.
Examples of do-it-yourself drawings of a jigsaw machine, which operates using muscle power, were repeatedly cited in various Soviet-era magazines.
Files for such a jigsaw machine are produced in the form of a flat blade.
Main parts of the machine:
- Bed (A).
- A work table with a slot for a saw (B).
- A large drive pulley that acts as a flywheel (D).
- Small drive pulley. The drive is combined with a crank mechanism (D).
- Levers (B).
- A pedal that spins the flywheel through the crank assembly (E).
- Saw tension unit (G).
The master, constantly pressing the pedal with his foot, spins the flywheel. Through the belt, the movement of the flywheel is transmitted to the second pulley. Which, in turn, causes the crank mechanism with the saw blade to move.
If the flywheel is correctly balanced, without distortions and with a uniform, correctly selected mass, then the file achieves good smooth running. A similar machine for cutting plywood allows you to quickly produce many simple, similar products. The time and effort required for sawing is significantly reduced.
With this machine design, the size of the initial workpiece is limited. It depends on the length of the levers (B). When complicating the pattern, it is necessary to rotate the product around the saw.
Since the foot drive does not ensure a completely uniform stroke and limits the freedom and imagination of the master, most often such machines are replaced with electric ones.
Construction of a jigsaw machine
An electric band jigsaw is a universal household device for making souvenirs, furniture, and various interior items. There are many options for manufacturing such machines. But the main elements on which the quality of the product and ease of use depend are the electric motor and the blade.
Main design elements:
- Saw blade.
- Crank mechanism.
- Drive part.
- Belt tension unit.
- Stand or work table.
- Various auxiliary elements.
Design and principle of operation
Conversion from a hand jigsaw
The first step is to make a working table for the mechanism. A metal sheet or thick plywood is suitable for these purposes. Holes for the cutting tape and fasteners are drilled and sawed out in the worksheet.
The jigsaw table is then placed on a regular table. Once secured, the guide rails can be assembled. To reduce vibration, simply cut a rubber pad of the desired size and place it between the jigsaw table and the main surface.
The above design is convenient in that it can be easily disassembled and can be used again as a hand jigsaw.
Since the standard device has springs that tension the saw, a rocker arm is necessary. One edge of the rocker arm is attached to the cutting element of the machine, and the second is under tension from springs. These simple steps will easily turn an ordinary jigsaw into a machine.
When operating the device, it is important not to forget to turn off the pendulum stroke before starting cutting.
Assembly from a sewing machine
You can also quickly and easily assemble a homemade jigsaw from a sewing machine. Moreover, this device has an interesting feature - a regulator for the stroke of the nail file, since sewing machines have a speed switch.
First, at the bottom of the machine you need to find a thread weaving knot. To do this, several screws are unscrewed. The cotter pin located inside is knocked out and the drive shaft, which is connected to the thread weaving complex, is removed. After completing this procedure, the top panel is unscrewed. The groove along which the needle rode widens slightly to accommodate the saw blade. The files themselves are shortened slightly to the length of the needle. To fix the saw itself, you can make an adapter. But the easiest way is to grind off the top part of the cutting blade and sharpen the bottom. After which you can insert the nail file into place of the needle and get to work.
When working with jigsaws of any type, you should not forget about safety rules. Do not leave the device turned 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 of your clothes. The room should be well ventilated. In the room where carpentry work is carried out, a first aid kit with emergency aid for cuts must be kept.
Cutting plywood with a hand jigsaw requires attention and time. The result is beautiful, practical products.
A hand saw is used to process the material to create decorative elements. As a result of processing wood, plywood, and plastic, crafts are created that have practical application and aesthetic value.
Figure sawing is a fascinating hobby that brings practical, moral and material benefits. From plywood and wooden blanks you can make:
- a vase for sweets;
- basket;
- table stand for postcards;
- lamp;
- hanger in the hallway, living room;
- photo frame;
- pincushion;
- bread box;
- panel;
- candlestick;
- hot stand for eggs;
- box.
For beginners, for carving, you can choose light drawings, simple diagrams, drawings of crafts, sketches that have a pleasant appearance. After mastering the cutting technique, you can try your hand at jewelry models with openwork fragments.
Using a jigsaw you can make platbands for home design. The variety of sketches allows you to create this element, which will provide artistic decoration of the interior. By figure cutting you can make crafts from wood.
You can cut beautiful decorative elements from plywood. Using jigsaw stencils, you can easily make photo frames, mirrors, and much more from blanks. Handmade will complement the design of the room and emphasize the chosen style.
Operating procedure
To obtain a high-quality product and minimize the formation of defects, you need to do the work slowly and focus on the process. Before starting work, it is recommended to make sure that the thickness of the plywood is equal to the height of the groove on the printed sketch.
Preparing the stencil
Schemes for sawing with a tool can be of different sizes. To create a drawing of an interior item, for example a shelf, you will need to use whatman paper in A1 or A0 format, and for toys you can use a standard sheet of cardboard.
The contour of the product is applied to the surface in compliance with the exact dimensions. Templates for cutting with a hand jigsaw can be found on special resources. But it’s easier to come up with your own compositions based on the type of workpiece. An individual approach to developing a product design will highlight the texture of the wood.
Transferring an image to the surface of plywood or boards
To accurately apply a contour to the surface of plywood or wood, print the template on thick paper. Transferring a drawing from an A4 drawing can cause a lot of trouble if you draw the ornament with a pencil.
In order to apply contours and complex patterns, you can use auxiliary methods. One method involves using carbon paper. To do this, the carbon copy is placed on the workpiece. Place a template on top and draw lines.
The drawing can be glued to the plywood with 2-sided tape. When using glue, you need to clean the surface with sandpaper. An accessible method involves using a stencil made using nail scissors. After preparation, the template is applied to the surface and each fragment is outlined with a pencil.
For convenience, the sheet is secured with tape or insulating tape. The design can be applied thermally. For this, an inkjet printer is used, with which the diagram is printed. After this, the design is applied to the surface with the front side and processed with a heated iron.
Sawing process technology
Sawing from plywood is carried out after applying the drawing to the workpiece. Processing begins with the internal elements of the product, and then the outer contour is cut out. This order of work allows you to get a straight line and provides convenient fastening of the workpiece.
Holes for the blade must be drilled in sharp places on the internal contour. This requires attention as chips may form on the back side. To avoid this, it is recommended not to make the holes completely.
You can limit the depth using insulating tape that is wrapped around the drill. After this, turn the workpiece over and process the hole with an awl. After finishing the work, the product is polished using a file or needle file.
Small elements require delicate handling, so it is recommended to be smart when processing. To do this, cut a thin strip of sandpaper and insert it into a jigsaw file instead of a blade.
Sawing with hand tools requires the equipment of a special machine with a clamp. This device is used as a base. During processing, the workpiece is fixed at chest level, which provides convenience and allows you to closely monitor the process.
For beginners, it is important to be careful when using a jigsaw in order to practice smooth movements. Jigsaw cutting blade fragile Therefore, it is recommended to avoid distortions, sudden movements, and overheating.
When processing a workpiece, the movements must be reciprocating, and the tool must be positioned vertically. Using an electric jigsaw requires securing the workpiece to a workbench. When using this equipment, workpieces up to 5 cm thick can be processed.
Defects in work
If the workpiece processing technology is violated, the tool may shift. A jigsaw may cut crookedly if the tool is tilted or improperly fastened. If the blade gets stuck at the stage of forming the figured elements, then you will need to carefully draw a new line located parallel to the fragment with the defect.
A little about safety
The jigsaw for figured cutting is an arched frame. The tool is equipped with a handle and 2 attachments for a cutting blade, which allow you to cut patterns of varying complexity.
Depending on the type of work, different attachments are selected. Thick saws are used to cut out contours, and thin blades are used for openwork work. The workpiece processing process can be mechanized using electric tools. To speed up the process, some models are equipped with a pendulum mechanism.
A stationary electric tool, which is mounted on a static surface, is similar in principle to a sewing machine. The use of this type of equipment eliminates perpendicular cutting errors.
Sawing with a jigsaw requires compliance with safety rules. The workplace must be properly equipped. When working, it is recommended to use personal protective equipment.
