Instructions

First, make a special stand for ease of use. It is a solid plank about twenty centimeters long, five centimeters wide and 1.5-2 centimeters thick. On the one hand, at a distance of five centimeters from the edge, a hole with a diameter of 15 millimeters is drilled in the center. Then, stepping back from the edges of the board one centimeter to the left and right, cuts are made to the edges of the hole. It turns out a curly neckline, reminiscent of a keyhole.

The stand is screwed to the table (workbench) with screws or fixed with a clamp so that it protrudes 15 centimeters perpendicular to the table. Working with a jigsaw without a stand is inconvenient, so it's worth spending a little time making it.

They work with a jigsaw while sitting on a chair. A material such as a plywood plate is placed on the stand and held with the left hand. When working, the jigsaw is held so that the file is strictly vertical. Without pressing too hard, gently move the jigsaw up and down, making sure that the file goes exactly along the line you have drawn.

As the file follows the outline, move the plywood sheet so that the cut is always inside the curved cutout of the stand. For smooth turning turn the jigsaw slightly to the left or right. If you need to make a sharp turn - for example, at - then in the place of turning, work with a jigsaw in place, without moving it forward and gradually turning in the right side.

If you need to make an inner cut - for example, cut a circle inside a part - then first drill a hole in the area to be cut with a drill. Unscrew the top screw on the jigsaw holding the file. Carefully so as not to break, insert the file from below into drilled hole and re-secure in the jigsaw clamp. After that, start cutting out the part to be removed. After sawing it, loosen the screw again and pull out the file.

When working with a jigsaw, the degree of saw tension is very important. If the saw is too loose, it does not cut well. With strong tension, it is easy. Always tighten the screws securing the file securely to prevent the file from slipping out. But don't rip off the threads on them. With a little bit of jigsaw work, you will, from your own experience, determine the required degree of saw blade tension and screw tightening.

In the event that you have to cut hard material - for example, textolite or other plastic, moisten the cut with water. When working with soft plastic, make sure that the file does not get stuck in the material melted from friction, for this, moisten it with water too.

With a saw, the tool should be set to the cutting line. The guide is squeezed with the platform side. After that, they start cutting.

The tool moves forward smoothly and the platform is carefully controlled. The platform and the rail must move towards each other so that nothing moves. The sawn off part must be carefully held with a few centimeters left to the end. Then the part will not break off.

What to do if you have problems with accuracy

• The main requirement is the reliable fixing of the material for which processing is required. In addition, the cutting should be convenient for the person himself.
• It is better to use guides if there is great doubt that the person will be able to do the job. For example, wooden block will be an excellent guide for straight cuts. It is simply fixed along the markings. It is much more difficult when the shape of the future product is quite complex. Then the use of patterns is recommended. Otherwise, the speed of work will have to be reduced to make the result more accurate.
• Saw problems are one of the most common problems when sawing. There is a possibility of chips, dullness. It is better to inspect if it is noticeable that the tool is strongly retracted to the side.
• If there are jerks, there is a possibility that the cut will go to the side. Other failures in the instrument also lead to a drop in accuracy. It is recommended that you start fixing such problems right away, on the spot.
• The skill of the performer himself also affects the accuracy of the final work.

Professional secrets

It is imperative to check how firmly the canvas is fixed.

This mechanism can have its own characteristics, depending on the manufacturer.

For working with any cutting tools, the fastening of the blade, its general position, is really important.

A useful device will be responsible for the removal of sawdust. Its principle of operation is very simple. There is a flow of air from the fan cooling the motor.

It is used to remove debris. The retract system makes the cut line more visible to the eye of the craftsman.

The drill can be easily replaced when making holes using a technique called "pocket". To do this, it is enough to tilt the jigsaw forward, then the tips with a rounded shape will rest on the cut surface.

Above the line of the future cut, the blade must be positioned with maximum accuracy. Lower the control saw horizontally and then continue practicing.

For such work, first marks are made inside the material, and then, already along them, the instrument itself is found. With a square or rectangular shape, the canvas is pulled back a little before the wizard guides the tool to the next side. And so all four are processed.

The use of plunge sawing is permissible if it is impossible to create holes of the required dimensions. For this, the jigsaw tilts forward until the file reaches the workpiece. Gradually, a through hole appears during this process.

What else you need to know about working with a jigsaw

At its core, this device- this is an ordinary saw, only equipped with an electric motor. It is recommended to take for carpentry work when it is necessary to cut surfaces with wide, even sides.

In this case, the tool itself remains in place. The movement is organized only by the material that needs processing.

The cut is performed with back side, then its characteristics will please.

• Machine oil for lubrication is needed if work is carried out with metal, tiles.
• Cold water should cool the cut line when processing metal.
• Personal protection cannot be provided without glasses and gloves.
• With an electric jigsaw, plastic is processed only from the rear, otherwise it is impossible to get an even cut.

A special plate is attached to the support sole of the jigsaw, it allows for greater accuracy. This makes the movement of the saw blades smoother over the surface. Any will be cut exactly.

About the varieties of the instrument

First of all, they are professional or household. Professional means the fixture will have a lot of power. It is usually 580-720 watts. But for household appliances it is less, only 320 watts. But this is quite enough for a small amount of work at home.

The higher the power of the tool, the thicker material it handles without problems.

Any type of tool can handle holes up to 15 mm. But we must take into account that jigsaws, in which 1000 rpm is equal to the lowest speed, will not cope even with plastic.

Jigsaws are sometimes divided into groups depending on how the saw is attached to them. For example, for a bore shank, smooth or cruciform. The latter two have become the most common since they are best suited to household tools.

Design and its features

Each jigsaw has a so-called support sole. It always rests on the part that needs to be cut. Thanks to this, the accuracy of the work is significantly increased.

The sole can be easily rotated to make bevel cuts. Some manufacturers produce in which the main tool is fixed only at a certain angle.

The file acts as the main cutting tool... Breeding of teeth, method of sharpening, size, shape, materials - they are literally different for each model. 75, 85 and 100 millimeters are the most suitable lengths if you need to cut low density materials. Saw step size is also becoming a fairly important parameter.

• Metal requires a pitch of 12 millimeters.
• Have wooden products he is from 2.5 to 4.

About accessories

No special effort is required to obtain maximum results. The tool can work as a stand-alone fixture without any additions. But there are parts that can increase the working capacity of a conventional jigsaw.

Usually, in order to cut an even circle from a piece of plywood or board, craftsmen resort to different kinds routers, use hand or electric jigsaws, and, at worst, take up a hacksaw. Meanwhile, with the help simple adaptation you can also cut an absolutely even circle with a circular saw. How to implement this in practice, read and see the detailed step-by-step instructions.

Materials (edit)

Before you cut an even circle with a circular saw, make sure you have necessary materials... The latter you need quite a bit:

• a piece of plywood;
• meter;
• the circular saw itself;
• nails or screws.

Step 1... Take a meter and measure the depth, length and width of the gutter on the worktop of the table circular saw... Based on the obtained parameters, cut a block of suitable thickness from a piece of plywood.

Step 2... Insert the timber into the groove and adjust the edges if necessary. The beam should easily slide along the gutter without catching it.

Step 3... Leaving the block in the gutter, lay on top of it square piece plywood. Install it so that it does not interfere with the saw itself.

Step 4... Screw the plywood firmly to the bar with self-tapping screws. When choosing fastening materials, pay attention to their length. Self-tapping screws when screwing in should not damage the surface of the work table.

Step 5... Take a piece of plywood or board from which you want to cut an even circle. Fit it to the square shape. Place the plywood on top of the prepared structure and drive in a nail exactly in the middle. Do not drive in the nail all the way. The plywood from which the circle is to be cut should rotate freely, and the nail itself will need to be carefully removed upon completion of the work.

Step 6... Rotating the square in a circle, cut off the corners to make an octagon.

Step 7... Continuing to rotate the square and further, cut it sharp corners... At the end of the work, carefully sand the slightest irregularities. So, without extra effort you will get an even circle cut from the board with a regular circular saw.

Often questions arise how to cut a circle with a jigsaw, since many craftsmen are faced only with straight cuts of the material. But cutting out various degrees of curvilinearity seems difficult only at first glance.

For cutting you will need:

• jigsaw;
• plywood or other material;
• files for special purposes, depending on the material;
• marker;
• sample;
• working surface;
• clamp.

Exists different ways... You can cut a circle with either a hand or a mechanical jigsaw. A hand tool is a simpler tool than an electric one. It is not suitable for thick material or long cuts. Electric jigsaws are divided into ordinary and artistic. The difference between them is in the location of the file: for an ordinary file it is located vertically, and in the artistic role of the file is played by a steel sheet. A regular jigsaw can be used to cut into thick plywood, for making a headboard or other furniture. Artistic can cut out complex elements, letters, puzzle pieces.

The cutting blades are varied for each type of jigsaw, and you need to select them according to the material with which you are working.

How to cut with a jigsaw from plywood?

Before you cut a circle out of plywood, there are a few things to remember. general advice to work with this material. Sawing can only be done on dry material. Wet plywood has increased resistance, and when sawing, the veneer will begin to flake, which will damage the file or even the entire tool in the case of electric models... At the first sign that the teeth are not sharp enough or some part of the blade is bent, the file should be replaced.

When sawing plywood with a jigsaw, it is necessary to place the main cutting lines along the veneer fibers, if possible.

This will help keep the cut edges clean. When working with a hand jigsaw, it is easier to cut across the grain. This will not protect you from chips, but it will be less likely that the file will be pinched or it will go along the chip away from the intended line.

Before you cut the circle, you need to transfer its contours to the plywood. In this case, you need to try so that areas with defects, chips, spots and knots fall outside the cut-out contour. You can transfer the contour to plywood by tracing it through carbon paper, cutting out the paper contour for the tracing, or simply drawing a circle of the required radius with a compass. If necessary, the starting hole in the plywood is made with a thin drill.

To cut a circle with a jigsaw, a blade is inserted into the hole. Free end at hand model fixed in place again with a clamp or retaining screw. The workpiece is pressed against the workbench with clamps, the cut is made according to the transferred line. When the circle is complete central element is detached from the sheet and the edges are processed sandpaper or with a file.

Before cutting with a jigsaw with an electric motor, you need to install a narrow file on it. There is a special enhancement for this tool, called a circular cutter, which is set in the center and started to work. When working on the tool, do not apply pressure, this does not contribute to a faster stroke. As a result of the pressure, the jigsaw file and even its fasteners can bend and break. If the circle you want to cut has a small radius, it is best to complete the job in several passes, as tight turns can break and bend the blade.

Plywood, unlike others sheet materials, due to its dense and not loose structure, lends itself to easy sawing and obtaining various decorative complex shapes... Possessing standard set tools, any House master able to cut out of this material any desired, and even complex elements. However, in order for the blanks to have marketable condition and did not violate the intended decor element, you need to take into account some of the nuances of working with plywood. How to cut an even circle from plywood?

Many have cut parts out of plywood more than once, but mostly they had to make straight cut lines. It is not often necessary to cut out rounded or wavy parts; few people dared to make a circle out of plywood. Therefore, at first glance, this task may seem impossible. For curly sawing you will need the following tools:

• The jigsaw is ordinary. A tool often used for do-it-yourself sawing of thin sheet materials. However, thick thicknesses are beyond his power;
• Electric jigsaw. Such a power tool is divided into two types of devices: ordinary, in which the file is located vertically, and for artwork, in which the working element is a steel blade, as can be seen in the photo. A regular jigsaw is suitable for working with thick plywood, but it will not work to make an even circle out of plywood with it. But curved elements, such as letters, can be cut by an artistic jigsaw, which is equipped with band saw... Thus, for quality performance of various kinds work, the appropriate device is selected.
• With more sophisticated equipment, such as a router, a plywood circle can be cut very smoothly. Of course, it is more difficult to control it, but it can be used to cut a circle of plywood from sheets with a sufficiently large thickness. The quality of work on such a machine surpasses other cutting methods, and the cut of the circle is smooth.

1. Patterns of drawings should be located on a sheet of the workpiece so that places with damage and flaws then go to waste, and clean areas are under the picture, that is, in the future they pass into the category of a finished product;
2. Before cutting a circle out of plywood with a jigsaw, you need to make sure that the material is completely dry. Since moisture increases the resistance of plywood, and as a result, the veneer can either peel off, or the tool can break;
3. To cut the edges of the cut without chipping and burrs, cut with a jigsaw along the veneer fibers. Hand jigsaw on the contrary, it is necessary to cut across the veneer fibers, although chips may form, but there is no risk that the file will deviate from the cutting line;
4. As soon as it becomes noticeable that the cutting teeth are dull, it is immediately necessary to change the working blade or saw.

Curly cutting methods

Before starting the work of sawing with a jigsaw, a sketch of the drawing is preliminarily applied to the sheet using carbon paper. The original holes are drilled with a drill. A file or a jigsaw working element is inserted into it and the free edge of the saw is fixed with a clamp or screw. Next, cutting is performed according to the template transferred to the plywood. Then unnecessary elements are removed, and the workpiece is sanded around the edges with sandpaper, or processed with a file. The video shows this process.

A furniture cutter is not suitable for cutting complex shapes, but it is very easy to cut a circle out of plywood evenly. A standard ruler of this machine is fixed in the center of the circle using a self-tapping screw. When the cutter begins to rotate along a given radius, a completely flat circle is cut. To correctly calculate the diameter of the circle, it is necessary to take into account the dimensions of the cutting cutter. You can correctly navigate this issue by first studying the instructions for the equipment.

How to make curly blanks using various tools and machines is described above, and if you had nothing at hand, how to cut a circle out of plywood without a jigsaw.

Here simplest technology cutting a circle out of a slab of plywood, with a few simple items available:

• Take a wooden plank and two nails. The first nail is driven into the center of the intended circle through the bar. The second nail is driven into the bar so that its sharp edge extends five, ten millimeters beyond the bar;
• The distance between the fixed nails will be the radius for the required circle;
• Making rotational movements, a line is made on the plywood. Wrapping the bar many times, the furrow is made deeper and deeper.
• The sharper the nail is chosen, the sooner the drawn line will receive a depression;
• The plank is easily replaced with a cord, the following cutting steps remain unchanged.

The above method is one of the least effective, but it also has a right to exist. And if you have a jigsaw, the work of cutting a circle with your own hands will not be difficult.
