How to use a jigsaw for wood correctly
When an electric plane is used
The advantage of the electric planer is that it can carry out various woodworking jobs with minimal effort. The electric plane can be used for rough, finishing and curly surface finishing. The tool is effective when it is necessary to perform large volumes of work in carpentry shops or when carrying out repair and construction work. The main disadvantage of the tool is that it is quite expensive, and therefore it is not profitable to buy it for home use if you plan to use the device only once.
Structurally, the tool is a massive plane equipped with an electric motor and special knives. The knives are driven by an electric motor by means of a gearbox. The electric tool has the function of adjusting the planing depth, the maximum value of which reaches 82-100 mm, depending on the brand and power. The electric planer has some more disadvantages:
- Noisy when working
- Dustiness. this drawback can be easily eliminated by using a special bag or connecting a hose from a vacuum cleaner
However, against the background of such advantages as fast and efficient removal of chips from the surface of the workpiece, the devices in question are popular. An alternative replacement for the electric plane is an angle grinder with a special attachment. Such a nozzle is called an angle grinder planer for woodworking.
How to distinguish a scherhebel and a jointer from a plane
Some types of planers have the same external design, which raises the question of their difference. For example, what is the difference between a scherhebel and a regular plane? Scherhebel, unlike a planer, is intended exclusively for rough cleaning of the surface of wood materials. Structurally, it differs in the shape of the cutter, which has a semicircular appearance. In addition, the width of the cutting part of the scherhebel is less than that of the plane, but it protrudes by 2-3 mm, in contrast to the plane, where its protrusion is up to 1-2 mm.
Another type of woodworking tool has the same external structure with a plane. jointer and half-jointer. However, there is still a difference, and it lies in the size of these instruments. A jointer differs from a planer in the number of blades, of which there are two on the first tool (depending on the model). The jointer is designed to perform similar tasks with a planer, but due to its two blades and a long length, it is used for finishing surfaces of large volumes.
Shape cutting tools or planers for complex geometries
A separate category of woodworking tools, with the help of which parts with complex geometric shapes are manufactured. Structurally, they are similar to the classic plane, however, they have corresponding distinctive features. There are the following types of planers for curly cutting:
- Zenzubel is a tool with a double knife, the use of which allows you to achieve a high quality of the processed surface. Effective for planing perpendicular surfaces and stripping quarters. The knife of the device reaches 33 mm in width, and in shape it is more similar to a shovel. The zenzubel is a close relative of the falzebel
- Federgubel. serves for making longitudinal protrusions on workpieces. Has a special blade design, through which the corresponding grooving is carried out
- Falzebel is the best tool for stripping quarters. The design of the device contains straight and oblique incisors, and the sole is of a stepped design. The stepped design allows you to select the folds that match the desired profile and dimensions
- Stacker. has a rounded blade format, through which concave parts are processed quickly and efficiently. This tool is also called a stacker, which is actually related to its design.
- Groove. the device has two pads, which are connected to each other by means of two screws. The device is used to create longitudinal grooves on the edges. One part acts as a guide, and the second is equipped with knives, and performs the necessary manipulations
- Kalevka is one of the main tools for performing shape cutting in wood. The tool found its application in the production of wooden cornices, baguettes and door slopes. The device is equipped with cutting knives with a curly edge. The multi-stage sole is selected depending on what you want to get in the end result
- A primer is a block on which a trapezoidal cutter is installed on the side. Allows you to carve a groove in a part in the longitudinal direction of the fibers. It has two handles, as well as an adjusting mechanism, by means of which the depth of the resulting groove is set
- Extractor. designed for profile planing of wood
- Gorbach. has a design corresponding to the name. The curvilinear shape of the tool makes it possible to process the surfaces of round workpieces. over, the processing is carried out not only on the outer, but also on the inner diameter of the workpieces.
In the garage, one hand plane is enough, but all the above tools should be present in the carpentry workshop. Some of them, although they are interchangeable, but to perform quality work, you need to use only the right devices.
Types of wood planers and how to use the tool correctly
Carpentry work involves the use of various woodworking tools. A separate class of tools for woodworking is occupied by planers. Each master gets acquainted with them from school, when the task of making a workpiece was at the lessons of labors. The wood plane, although it is morally outdated, but when the need for chamfering arises, it is always able to help out the master.
General Purpose Appliances or How to Roughly Finish a Part
A separate category of planers is universal devices for rough and final cleaning. With their help, you can perform not only rough, but also fine surface finishing. One of the most important tools of a carpenter is the scherhebel. With its help, the master carries out the initial planing of the wood, that is, the removal of the bark. In more detail about what types of general-purpose planers are, we will consider further.
- Sherhebel. looks like an ordinary plane in a metal case. The main task of the tool in question is to give the workpiece the necessary shape for its subsequent processing. The tool allows cutting edges up to 3 mm thick. It is almost impossible to get a flat surface with a scherhebel, therefore, after work, you will need to perform finishing with other tools. The scherhebel differs from a conventional planer in that the cutting part with a rounded blade is located at an angle of 45 degrees. The presence of a rounded blade makes it possible to plan wood in the transverse direction
- Medvedka. got its name due to the similarity in shape with the insect of the same name. The similarity is due to the design of the elongated handles with side protrusions. Used for leveling large surfaces. The special protruding handles allow for easy use of the tool, which is equally convenient for both right-handers and left-handers. Medvedka is also intended for use by two people in pairs. The metal cutting tool is fixed with a wedge. The cutter protrudes from the sole by 1 mm, which allows the removal of the corresponding layer of wood
- Jointer. the device is equipped with two cutters, therefore, unlike the scherhebel and the bear, it is used for the finishing or final leveling of the corresponding wood surfaces. A distinctive feature of the jointer is its large length, whereby in one pass it is possible to remove chips from a large surface area. In the design of the tool, not only two, but also one blade can be used
- A half-jointer is an analogue of a jointer, which has a shortened length of up to 60 cm.The design uses a double cutter, and serves as a tool for finishing the surface of a small-sized material
With the help of these four tools, you can carry out a complete material processing from start to finish, that is, from removing the bark to making the required size and shape of the part. It should be understood that these tools will not be able to get a perfectly flat surface, therefore, if necessary, you will need to use additional devices for finishing and figured processing.
Types of hand planers and their purpose
Woodworking tools are divided into the following types for their intended purpose:
- Curly cutting
- Rough machining or for general use
Finishing planers include the following tools:
- Grinder is a tool by means of which the finishing of wooden surfaces is carried out. With its help, the wizard removes irregularities and defects that remain from the use of the previous tool. The device is based on two sharp knives, the sharpening angle of which is 60 degrees. An additional grinding element is a chipbreaker. The chipbreaker is the shim that sits above the cutting insert.
- Zinubel is a device that belongs to the category of tools for finishing. By means of this device, the roughening of the wooden surfaces is carried out. This roughness is similar to the ground surface (adhesion), which is necessary to improve the quality of adhesion, for example, when applying varnish. The incisors are set at 80 degrees and have grooves. Zinubel design uses single knives with a serrated blade at the end
- End planer. used when it is necessary to process small-sized wood. The name of the device does not speak of design, but of application, that is, it is used for planing the end surfaces of workpieces
- Single. used for re-processing wood. The use of the device allows you to get clean chips without fractures, but at the same time chips and scuffs are formed on the processed material. That is why, after using a single planer, you will need to rework with a sander.
- Double planer. equipped with a cutter and chip breaker, which improves the quality of planing work. After this device, you will also need to grind the wood.
If it becomes necessary to perform finishing processing of woodworking materials, then the above is a complete list of such devices. They are also called flat planers. After processing the surface with a grinder, proceed to the use of sandpaper, through which grinding is carried out.
Features of the right choice of tool or what you need to know
An ordinary hand plane is probably present in the arsenal among the tools of every master. However, if you need to purchase it, you need to know some features that will help not only save money, but also choose an effective woodworking appliance.
- Outsole. the first step is to inspect the bottom of the tool, which should be perfectly flat, smooth and free of visible damage and chips. This applies to all types of planers. It will not be possible to visually determine the maximum evenness, but if the base is massive, then even minor irregularities can be removed when preparing the tool for work
- A knife is a working element, the quality of which affects not only the efficiency of the work, but also the service life of the tool. It is necessary to choose such models on which the knives are made of tool steel. Such material, in addition to being sharp for a long time, does not undergo wear and tear. Factory planers have a blade that is fixed rigidly to the body without any backlash
- Handles. when choosing, you need to take the tool in hand and try it out. If the handles are small, then it is better to choose a plane with large handles. After all, its use and, accordingly, the quality of work depends on how comfortable it will be to lay the plane in hand.
It is important to pay attention to the question of who is the manufacturer of planers. The most popular are Japanese firms Sigma and Stanley, but there are other models. It should also be noted that today it is much easier to find an electric plane than a hand tool.
Design features of planers
You need to start by considering the purpose of the tool. And it is intended for planing wood, that is, to give a wooden surface the desired shape, while eliminating various irregularities, roughness and other defects. The constituent elements of the device are:
- Wood or metal body. last with sole
- Steel knife, iron or cutter. the main cutting element
A more detailed design of a hand planer for wood is shown in the photo below.
The basis of this tool is a cutter, which looks like a rectangular plate with a pointed end. The plate is placed in the opening of the shoe at an appropriate angle. A special adjustment mechanism allows you to set the knife at the required distance. This distance is set in order to adjust the depth of cut and the thickness of the chip. According to the standard, the blade has a certain sharpening angle, but if the tool is used by a professional, the master sharpens the cutter on his own, depending on what type of wood is to be processed.
An equally important element in the design of the tool is the handle. over, the hand plane consists of two handles, one of which is a guide, and the other is persistent. The guide handle has a curved design that allows the hand to grip the tool. The thrust handle allows you to create the necessary force when performing work.
The body has a smooth surface, from which a sharp incisor protrudes. The main condition for the instrument is a perfectly flat and smooth sole. If the sole is not even, then it will simply not be possible to perform precise processing. The tool body is made of wood or metal. Home craftsmen give preference to wooden planers, which are cheaper. Carpenters prefer to work with metal planes, the base of which is made of gray cast iron.
Despite the fact that the hand tool in question has a typical design, more than 10 varieties of these woodworking devices are known today. To begin with, it should be noted that all types of planers are divided into two main groups according to the type of drive. manual and electric.
It is interesting! Electric planers are replacing hand tools, but when it is necessary to plan wood, DIYers prefer the second option.
What material is better to work with
For cutting thin patterns, it is better to use thin, sanded plywood, 3-5 mm thick. Sawing such material is much easier, even for those who do not know how to use a hand jigsaw for wood, and the chance of ruining the product is significantly lower.
Another interesting material suitable for cutting with a hand jigsaw is sheet polystyrene (not to be confused with expanded polystyrene). In fact, it is a durable plastic that can be of all colors and sizes. In order not to complicate manual sawing, it is better to work with sheets up to 5 mm thick. The beauty of polystyrene handicrafts is accompanied by the high price of the material (from 700 rubles per sq / m) and limited availability. If you are confident in your cutting skills, and are ready to create an original glossy craft, you can start your search from the local construction markets.
Sawing with a hand jigsaw (step by step instructions)
Any creative work, in any industry, requires certain knowledge and skills. If an author wants to create something truly valuable, his technique must be honed to the appropriate level. Such activities can be safely attributed to the work of a hand jigsaw. In skilled hands, this device, seemingly simple at first glance, can create real works of art. Fortunately, it takes quite a bit of time to master curly sawing. All you need is a desire, and we will be happy to provide a detailed guide to action.
How to apply a drawing to a workpiece
Stick the patterned paper onto double-sided tape or glue. In the second case, after cutting, the glued paper will have to be removed with sandpaper. Double-sided tape, you can gently peel off.
How to assemble a hand jigsaw
When the material is selected, and the cut-out contour is applied, you can start assembling the working tool. First of all, we tighten the file in the lower mount (near the handle), after which we thread the free end into the opposite groove and, slightly squeezing the frame, fix it in it. Be sure to remember that the saw blade teeth should always look at the tool handle.
When squeezing, do not put strong pressure on the frame trying to bend the metal arc. It is enough for the mounts to come close to each other by about 1 cm. You can squeeze the metal frame in your hand, or by resting the instrument with the handle on your chest. For devices with tubular arches, there are special devices with grooves. If you can’t tighten the lambs with your bare hand hard enough, use pliers.
If the saw blade is installed correctly, it does not wobble, and during operation, a high-pitched sound of teeth biting into the material is heard. How to properly assemble a jigsaw is best understood from the very beginning, since thin files tend to burst. The easier it is for you to assemble the device, the more pleasant it will be to work.
How to cut correctly
During shape sawing, you will often come across the same types of shapes. Despite the fact that the technology of cutting with a hand jigsaw is quite simple, it will be useful to know a few nuances:
Which jigsaw to choose?
Despite the simplicity of their design, modern hand jigsaws differ in a number of features that should be paid attention to when choosing. It is better to refuse models with a sheet iron frame by choosing a jigsaw made of a metal tube. This option provides better blade tension and eliminates skewing, so that the file will not “go away” during operation.
The saw is fixed in the frame by tightening the upper and lower wing nuts. When choosing a jigsaw, pay attention that it is equipped with lambs made of high-quality steel with wide ears. This will significantly increase the usability of the tool in the process.
What plywood is needed for cutting with a jigsaw?
Practice shows that the best material for working with a hand jigsaw is birch plywood with a thickness of 2 to 8 mm. It is affordable, easy to handle and highly durable.
To create small details or a “dense” openwork pattern, it is more appropriate to use three-layer plywood up to 3 mm thick. It is easy to cut and is quite durable. The likelihood that you ruin the cut curl with the next seizing of the canvas is significantly lower.
When choosing material for crafts, pay attention to the fact that the plywood is flat and without a lot of knots. Examine the end face for the presence of air chambers, their presence indicates an uneven application of glue. It is better to refuse such low-grade plywood, otherwise you cannot avoid a large number of chips that will spoil the appearance of the product.
And what about practicing basic techniques?
The most intricate patterns are always based on a number of basic shapes and elements, having worked out which you will be prepared for complex projects. It is desirable to do this on thin plywood up to 3 mm thick.
Obtuse and right angles: the jigsaw moves smoothly without pressing on the workpiece, as if idling; at this time, the second hand slowly turns the wooden workpiece to the desired angle.
Inner circular contour: for this, a small hole is drilled in the inner part of the figure through which the file is passed. When cutting a circle, the cutting line is cut along the inner contour of the pattern. The tool stroke should be of medium intensity; the workpiece unfolds in proportion to the movements of the jigsaw.
Oval outline: when cutting such a shape, increase the jigsaw stroke in steep sections, turning the workpiece in this place faster.
Sharp corners: A neat, sharp corner without chipping or other defects is obtained by converging two cuts.
Where do you recommend to start?
First of all, you should correctly organize the workspace. Despite the seeming formality, this is a very important condition. A properly equipped place provides not only comfort and convenience, which is important for many hours of work with a manual jigsaw, but also directly affects the quality of the project being implemented.
A special table-machine is used as a persistent structure, for which the name “dovetail” is stuck. It is a small rectangular board with a wedge-shaped cut that turns into the working field for sawing. The dovetail is attached to the edge of a table or workbench with a clamp.
They work with a manual jigsaw while sitting or standing, placing the workpiece for cutting at a level of 30-40 cm from the eyes. The light source is placed at the front at an angle to the work plane. Compliance with these rules will allow you to control the cutting line as accurately as possible, thereby improving the quality of the project being cut.
How to transfer a diagram to a piece of wood?
There are several convenient options for transferring a printed drawing to a wooden base:
- using carbon paper and redrawing the template by hand;
- gluing the sheet onto double-sided tape;
- sticking a picture on glue, the remnants of which are rubbed with sandpaper at the stage of finishing.
What if you use wooden blanks?
For all its practicality, plywood does not have such an expressive texture as a board. When sawing projects from planks, you can use these advantages: play on the difference in colors and shades, the orientation of the wood fibers (as in intarsia), etc. Wood crafts have a more attractive end (without a layered structure like plywood) and are much easier to process with a finishing compound.
For cutting with a hand jigsaw, workpieces from soft and hard rocks with a thickness of up to 10 mm are used. When choosing material, give preference to tangentially cut boards. It is not recommended to use radial cut blanks, because they have parallel annual rings, which, due to their hardness, will take the jigsaw away when sawing.
Need advice on why the file is sticking?
You have a good feel for the jigsaw, achieved a smooth ride and lead a neat cutting line, but then the movement of the tool becomes difficult and the file wedges in the workpiece. This is a typical situation when using a hand-held jigsaw to carve on plywood. It happens for the following reasons:
- Overheating of the saw blade. during prolonged use, the blade expands due to heating. To avoid such situations, take short breaks or periodically wipe the canvas with a damp cloth.
- Features of a wooden blank. The movement of the jigsaw can be difficult due to the fact that the file ran into a denser area: a knot, a lump of glue in plywood, etc.
- On long cuts, the saw can be clamped between two nearly separated pieces of plywood. You can continue cutting comfortably by securing the split ends with a clothespin.
How to use a jigsaw: 5 features of working with the tool
Connoisseurs of unusual design solutions are often delighted with pictures with beautiful rounded elements of furniture, stairs and structures that adorn the interior of houses. At first glance, such details are not available to ordinary users. But, having special electrical tools and learning how to work with them, you can create interesting interior things that emphasize the uniqueness and individuality of the style of the room.
One such hand tool is a jigsaw. This article describes how to work with a jigsaw for novice craftsmen, how to set it up, choose files and get the desired result.
Features of preparing the jigsaw for work
File selection. One of the main parameters of high-quality sawing is a correctly selected file. For each material, the corresponding type of this cutting tool is provided:
- If you want to make a straight cut in wood, then you should choose a blade with medium (or large) teeth. This file can be used to cut parquet, laminate, board. It is better to use files with a wide blade. On some saw models, you can see a special badge. clean for wood. this is how manufacturers mark products for wood processing. They are easier to manage without excessive effort. The smooth start function will help to ensure an even cut. the engine accelerates gradually, without jerking;
- For metal, it is better to take a narrow saw with fine teeth. The thickness of the cut in metal is usually 3 to 5 mm. The strongest alloys and stainless steel are easier to cut with a blade with the finest teeth. And for durable plastic and non-ferrous metals, you can choose a larger tooth size. Files for such operations are marked with the inscription. for metal;
- Ceramics or tiles are treated with a fabric without teeth. Instead, an abrasive compound is applied to the file, most often diamond spraying. The tool gently rounds the edges and makes a straight cut. Recognizing the canvas is not difficult. In addition to the absence of teeth, the lateral surface has a marker. special for ceramics;
- It is easiest to perform shape sawing with a narrow and thin file with a fine tooth. Such a blade is not clamped during turning operations, which contributes to accurate, error-free cutting. Hitachi CJ65V3 is considered one of the best tools for shape cutting. even carved furniture is too tough for this jigsaw.
How to insert a file into a jigsaw. Correctly fixing the file is necessary not only for accurate cutting, but also to prevent injuries during work. Jigsaws are available with different types of saw blade attachments:
- Shoe. The most used type of clamp. The blade is inserted into the block and clamped against the stop with two screws. Tighten the screws carefully, not skewing the file. Replacing a blunt blade is just as simple. the screws are loosened, the file is pulled out, a new one is inserted in its place.
- Screw. In such devices, the file is placed in a clamp and tightened with one screw. The canvas changes quickly and effortlessly. The main thing in the installation is to check the angle of the inserted saw. Experts recommend not to tighten the screw to the limit. this will lead to excessive vibration of the blade.
- Keyless. Not universal. This attachment is only used for a certain type of file. In addition, users have complaints about the reliability of the file fixation. Installation and replacement of the blade is performed as follows: the lever on the clamp is pulled back, the blunt blade is pulled out, a new blade is inserted, snaps into place, the lever is returned to its place.
Do not neglect the rules of working with such a tool. this can lead to injury. Therefore, it is important to know how to work correctly and safely with a jigsaw. A few tips for using:
- Be sure to wear safety glasses and a respirator;
- Do not lean on the jigsaw, achieving more significant pressure on the material;
- With any pause, the jigsaw should be turned off;
- Do not dismantle the protective screen;
- Securely fix the processed material;
- Turn off the instrument if smoke, sparks or abnormal noise appears.
How to work with a jigsaw: features and rules
When cutting straight or circular holes, it is important to select the correct mode. Both the quality of cutting and the safety of the tool itself depend on this. Experienced craftsmen intuitively feel the work of the tool, but there are basic recommendations for working with various materials.
Working with wood. It seems obvious to many craftsmen how to work with a jigsaw on wood. But there are nuances. For example, for soft woods, it is more advisable to cut at high speed. The denser and harder the wood, the lower the speed of movement of the saw should be. The pendulum motion of the 1st stage should be connected when working with workpieces more than 3 cm, and if the board is more than 5 cm thick, then it is better to switch to the 2nd stage and higher. For example, the GRAPHITE 58G061 in pendulum mode can handle a board up to 65 mm.
An interesting fact: many models of jigsaws, for example, Sparky TH 60E, are equipped with a pendulum function. This function allows the file to move not only up and down, but also slightly to the sides. The multistage pendulum movement is used only for straight sawing, for oversized workpieces or a large sawing volume, when productivity is needed, and the cleanliness of the cut can be neglected. Pendulum sawing speed is dramatically increased with little loss of quality.
Metal cutting. The metal is cut at low speed without the use of a pendulum mechanism. To improve the quality of the cut and reduce the loads on the tool, it is recommended to apply a special composition to the cutting line. water mixed with machine oil. In addition, it is imperative to pause in work to cool the tool. Makita JV0600K has proven itself to be excellent for such operations. you can connect a vacuum cleaner to it to collect sawdust.
Plastic cutting. The difficulty of sawing plastic and similar materials, such as plexiglass or PCB, is the fragility of the materials being processed. Despite their low hardness, they can deform, crack or chip. Therefore, it is better to cut them slowly, using a fine-toothed saw.
Working with other materials. A household jigsaw is often used to cut or round tiles and ceramic tiles. Its strength is low, so the processing speed should be set low, avoiding shock loads.
In any case, when trying to saw a material whose “behavior” is unknown, you need to consider its strength, thickness and hardness. To understand how best to set up a jigsaw for this material, you need to try different modes in non-critical areas of the workpiece, and the work of various files.

5 important recommendations
It takes a lot of practice to get used to working with a jigsaw like the Bosch GST 8000E and getting smooth cuts. The main thing is not to forget about the basic features of working with this power tool. So, tips for beginners on how to work with a jigsaw correctly:
- Before any operation, you should check the serviceability of the tool. only a well-functioning device can give a smooth and high-quality cut.
- The files must not be blunt. This is checked visually. sharp peaks of the teeth indicate a good condition of the cutting blade.
- When cutting, the bottom plane of the jigsaw must fit entirely on the surface of the workpiece. This guarantees a smooth cut and prevents vibration.
- Deformation of thin sheet material can be avoided by using a backing.
- It is important to follow the manufacturer’s instructions when selecting saws and cutting modes.
To better understand how to work with a jigsaw on wood, you should watch a video from experienced craftsmen.
Choosing saws for a jigsaw
Saws are purchased separately and are selected depending on the material of the cutting blade and whether you need a straight or curly cut. The packaging indicates the purpose of the saws, what material they are made of, as well as the direction and size of the teeth.
What can you saw with a jigsaw?
- wood, plywood;
One or another type of saw is selected depending on what you need to saw off.
Consider the varieties of jigsaw saws and determine what each of them can do.
- With a wide canvas. Designed for cutting saw blades along a straight mowing line. With a saw like this, you don’t have to put in a lot of effort, just make a little directional correction. For a more accurate cutting line, you need to turn on the “Soft start” function, in which the motor gradually picks up speed.
- Narrow saw. Needed for cutting material along a curved mowing line. To cut with maximum precision, use a tilting tool. The head turn radius depends on the selected jigsaw model.
- With coarse teeth. Their purpose is to cut quickly, while the quality is poor.
- Saws with fine teeth and a thin blade can cut the most complex shapes.
The quality of the jigsaw depends on the method of fastening the saw. When processing thick sheets with a high density of material, it is necessary to use equipment with a rigid mount.
Working with blunt saws can lead to tool breakage due to the increased load on the jigsaw motor. And also the quality of the cut will decrease.
How to prepare the instrument
It will be useful for beginners in this business to learn how to work with a jigsaw correctly, but first we will talk about preparing the tool for use:
- The first step is to carefully study the operating instructions for the electrical appliance.
- Visually assess the appearance of the device for damage: cracks, chips, cable integrity.
- Choose a saw in accordance with the quality of the material with which you have to work.
- Select the appropriate mode. Here are some examples: to work with soft tree species, it is necessary to set the maximum speed and apply a pendulum mechanism. If you need to cut a chipboard sheet, then leave the high speed of the cutting blade, but the pendulum mechanism will be superfluous here because it will contribute to the appearance of chips.
To avoid injury, you need to adhere to safety precautions when working with a jigsaw: wear protective goggles and gloves.
How to use a jigsaw correctly
Every man, being a real owner, should not only have repair tools in his arsenal, but also be able to apply them in practice. It will be about one of the modern tools, namely the jigsaw. Let’s figure out what kind of device it is and how to work with it.
Marking is an important detail, because you need to avoid chipping on the front side of the part. Please note that chips are often formed on the side of the sheet towards the person working. Most often this applies to chipboard and fiberboard sheets. Based on this, the markings must be applied on the back side, and the canvas must be placed with the front side away from you.
For an accurate cut, you need to mark without allowances, and guide the saw near the mowing line of the marking. For the convenience of work, the workpiece must be secured using a bench clamp or sawing table.
The jigsaw with an electric drive is a hand tool, however, if necessary, it can be secured using a stop bar and a parallel stop.
Sometimes you need to saw off a part covered with a layer of paint or varnish, and I really don’t want to scratch it. For this case, a plastic shoe or self-adhesive felt is provided.
In addition to files, rasp and grinding attachments can be installed on the tool. Thanks to the first, the corners are rounded, and with the help of the second they clean the finished product.
Some models provide for the use of a pendulum mechanism, due to which the sawing process is accelerated. This function is good for making rough cuts, as the quality and accuracy of the cut line will be reduced. When working with plastic and metal, the use of the pendulum mechanism is unacceptable.
What Can You Do With a Jigsaw? A Lot! | WOODWORKING BASICS
When working with a jigsaw, a lot of fine dust is formed, which harms the respiratory system. You can get rid of it by connecting a construction vacuum cleaner to the nozzle of the device, which will suck in all the dust generated during the operation of an electric jigsaw.
If the purchase of two tools is not affordable, a jigsaw with the function of blowing the working area will be enough for work.
The electric jigsaw is designed for cutting various sheet materials. Depending on the purpose, jigsaws are:
The differences lie in the technical characteristics and functionality of the tools.
Before you learn how to use a jigsaw, you need to familiarize yourself with its device. The tool consists of:
- Aluminum body.
- Electric motor. Powerful tool will be able to cut thicker and stronger material.
- Gearbox covers.
- Pendulum stroke control buttons. The pendulum mechanism allows you to make an accurate cut of materials with a low density (soft woods, plywood, foam).
- Covers and brackets for safe work.
- Support roller for sawing.
- Chip blowing regulator.
- Regulator of the number of strokes of the saw, on which the speed of its movement depends.
- Slab tilt adjuster. It allows you to cut wood at an angle of 15, 30, 45 and 90 degrees.
- Laser guide. Allows you to adhere to the drawn mowing line for cutting.
- Keyless chuck, which acts as a saw.
- Battery, thanks to which you can saw for some time with a jigsaw without being connected to the mains.
To find out how to properly saw with an electric jigsaw, our tips will help:
- Stronger is not better. This concerns the force of pressure on the device during operation. This style of sawing will break the tool. The correct use of the jigsaw is to firmly fix the device in the hand and direct the saw in the right direction.
- Vibration occurs when processing thin metal sheets. To eliminate it, you need to reduce the speed of the saw and put a sheet of plywood under the metal. When cutting such material, there is a large load on the jigsaw motor, so you should periodically turn off the device to cool the motor.
- For a high-quality and accurate cut, you need to fix the workpiece.
- In order to avoid chipping from the bottom or top side, for example, laminated chipboard, you must choose the right saw or turn the board the right side. But if there is a need to get a cut without chips on both sides, then on top of the chipboard you need to put a small piece of the same plate and start sawing. The chip will remain on the additional material, and the desired plate will be with a clean cut.
- To prevent chips from appearing, you can resort to this trick: glue adhesive tape according to the marking.
- When sawing such fragile material as plastic, we recommend installing a saw with medium teeth, turning off the pendulum mechanism and setting the saw speed to the smallest.
- In the event that it is necessary to cut out a part with a closed contour, and it is impossible to start sawing from the edge, then a hole is drilled in a convenient place, an electric jigsaw is inserted into it and work continues.
- To cut plexiglass or non-ferrous metals, the saw must be treated with machine oil.
We hope that our tips will help you, and if you have additional questions about how to use an electric jigsaw correctly, you can always watch the training video.
As it turned out, the jigsaw is an indispensable tool in everyday life that even a beginner can handle. And with the right approach and work experience, you can not only make straight cuts, but also cut out various curly details for decoration.
How to use a hand jigsaw?
Working with a manual jigsaw, even of the smallest size, is a painstaking and tedious task. In the previous section, it is no coincidence that there is no mention of the shape of the handle. all manufacturers have long worked out the most ergonomic shape for the jigsaw handle. However, my hands still get tired. In order for this to happen as late as possible, you must adhere to the following recommendations:
- A hand jigsaw, or rather, its replaceable blades, are not designed for making cuts at an angle. If necessary, figure sawing is paused and continued from the opposite side. Naturally, for this purpose, markings are first made in the place where the length of the cut deviates by more than 5. 10 ° from the horizontal / vertical.
- To save energy, especially for shape cutting, it is recommended to use the maximum saw swing: this not only increases the sawing speed, but also improves the conditions for chip removal. This is especially important for working with thick wood (more than 1.5 mm).
- Use only jigsaw blade designs that are designed for this purpose. For example, spiral blades are good for a figured cut, and spur blades are good for a straight cut.
- It is extremely inconvenient to work with a workpiece that is not securely fixed. Therefore, a clamping device or a reliable clamp is usually purchased for manual jigsaws, which will help to quickly and correctly fix the workpiece on the desktop.
- In order for the saw blade to be easily inserted into the gap, there must be a gap between the clamping surface and the upper end of the table, at least 3. 5 times the thickness of the workpiece.
- It should be remembered that a hand-held shape saw is not a saw, and any strong pressure on the frame can break the saw blade. Therefore, during the execution of the cuts, the effort is applied gradually. The criterion for the correct force is the nature of the generated chips. if they are small and uniform, then the force is optimal. When the pressing force is exceeded, the chips become coarse, and a burr begins to form on the surface of the cut.
- Often, when working with a hand jigsaw on wood, you have to make sharp turns of the saw blade. To exclude the breakage of the file, in the place of the intended turn, pre-drill a hole with a diameter of no more than the thickness of the workpiece material, insert the blade there, and, without tilting the frame, continue the cut.
Manual jigsaw for wood. Selection and work rules
Despite the abundance of electric jigsaws, manual versions of this tool are still trending. A hand jigsaw for wood is both good physical activity for the entire shoulder joint, and an increase in the level of your woodworking skills, and the ability to do what you love in any conditions.
How to choose a jigsaw?
- Lack of practical skills often leads to quick breakage of saw blades, because they do not take any bending loads poorly.
- Drive jigsaws are more often acquired by craftsmen who are engaged in the mass production of curly crafts from wood and plywood.
- It is impossible to cut a complex profile with an electric jigsaw.
- The primary skills of sawing with a hand jigsaw on wood have already been fixed at the level of manual labor lessons at school, so mastering the tool will go much faster.
So, a manual jigsaw is a tool that disposes to unhurried, thoughtful and quiet work somewhere in the country, or on the balcony. a good alternative to mechanized options.
The first step is to choose the right hand jigsaw itself. The selection criteria are usually:
- Frame shape: depending on its configuration, it will become clear what the maximum cutting length is. There are jigsaws on sale whose frame length reaches 300 mm, which significantly expands the technological capabilities of the tool, but at the same time leads to an increase in its weight and dimensions. For home craftsmen who have no experience in curly sawing, it is worth purchasing hand jigsaws with a frame length of no more than 150 mm.
- Frame material: when pressing on the bow, the frame should spring, which is a good sign of quality. such a frame will not break when noticeable lateral loads are applied to the hand jigsaw on wood.
- Frame height: for strength reasons, this parameter should not be more than three times the length, otherwise the rigidity of the jigsaw will decrease and the quality of the mowing line will be unsatisfactory.
- How to tension the saw blade: Typically, wing nuts with different lengths are used for this, which, in turn, depends on the diameter of the thread. With an increase in diameter, the length of the tendrils of the nut increases, which increases the convenience when tightening. The presence of holes in the antennae increases the accuracy of fixation. Nuts should not be cast, but stamped.
How much is a manual jigsaw for wood?
The price of the tool is determined by the manufacturer, based on the capabilities of the jigsaw. For example, a wooden handle is simpler and safer than a plastic one, but a jigsaw with such a handle will cost more, since durable types of wood (pear, hornbeam, oak) are used for the manufacture of this part.
The price of a hand jigsaw for curly cutting also depends on the design of the fixture. Aluminum wings are lighter, which has a positive effect on the weight of the tool, but negatively on its durability: over time, the aluminum wings on the nuts will begin to deform, and the quality of the saw blade clamping will deteriorate. Manual jigsaws for wood, equipped with brass or steel clamping nuts, are more reliable and durable.
The shape of the frame also contributes to pricing. rectangular frames reduce the cost of a jigsaw, and square frames increase.
Thus, manual jigsaws, adapted for household, and not for professional needs, will be cheaper. The rest will be determined by the characteristics of the saw blades.
