How to cut an even circle with a circular saw. The master cuts perfect circles with a jigsaw. Exactly cut a circle from plywood.

When working with various types wood you always need to know the detailed variations in its processing. Before you cut a circle in plywood, you need to know all the options, because you often have to adapt to the situation. There are many options for carrying out such an undertaking, and they differ radically.

In order to cut a circle from plywood, you can use both professional tools and improvised means.

Power tools or hand tools?

Tools and materials:

  • drill;
  • jigsaw;
  • hand jigsaw;
  • milling machine;
  • nails;
  • rope;
  • chisel;
  • hammer;
  • stationery knife;
  • sandpaper;
  • compass.

When determining the diameter of the future circle, it is necessary to take into account the dimensions of the working cutter.

The most popular option among all is a jigsaw. This tool allows you to cut not only circles, but also any other geometric shapes. Its only disadvantage is the need to form additional grooves at turning points (corners), but this is not noticeable when creating a circle. It is very important to choose the right nail file, because... they come in 3 types: vomiting on the left, vomiting on the right, vomiting on both sides. After the canvas is selected, cut out a circle of any size.

An ordinary hand jigsaw. Before cutting a circle from plywood using this tool, you need to make sure that the workflow is accessible. The main difficulty is the limitation (usually up to 30 cm) due to the physical structure, i.e. V deep places it won't work. When starting work, not from the edge, but directly from the center, the nail file is threaded last.

Milling machine. A very convenient option, but it requires rigid adhesion to the surface, for which a self-tapping screw is screwed into the center of the circle. A circle can be made of any diameter, and very quickly. Sometimes there is not enough working handle, which is why you have to make all sorts of improvised brackets, which can be a channel, a profile, a block, a board or even a rope, but with a rigid hitch it is much more convenient. This tool makes a fairly wide hole, so before starting work you need to carefully measure the future structure.

It is necessary to select only sharp nails, and process the edges of the resulting workpiece with coarse nails. sandpaper.

Nails. A very popular method in cases where the work must be done “yesterday”, but the tools will not be available soon. It is worth noting right away that the work ends up being quite rough, so it is used as a last resort. All you need is a hammer, 2 nails and a rope. One nail is driven in the center of the hole, and the other is pulled on a rope to the required length (radius), after which with a firm movement a circle is held. Such circles with pressure continue until the circle is finally cut out. At the very end, the nail is removed from the hole, turned over and carefully beaten with a hammer to achieve a more accurate seam.

Chisel and stationery knife. Here everything is much simpler, because first you need to draw a circle with a compass (pencil), after which this circle is circled several times with a stationery knife under pressure. The peculiarity of the stroke is the movement not of a knife, but of a sheet of plywood, so as not to break the metal, and this action is repeated on 2 sides. Then a chisel is applied to the prepared seam and with gentle blows it is brought to the opposite seam (2-3 blows are usually enough). At the very end, a circle is knocked out with a hammer, as in the version with nails.

Questions often arise about how to cut a circle with a jigsaw, since many craftsmen only deal with straight cuts of the material. But cutting out varying degrees of curvilinearity seems difficult only at first glance.

For cutting you will need:

  • jigsaw;
  • plywood or other material;
  • special purpose files depending on the material;
  • marker;
  • sample;
  • work surface;
  • clamp.

There are various ways. You can cut a circle with either a manual or mechanical jigsaw. A hand tool is a simpler device than an electric one. It is not suitable for thick layers of material or for long cuts. Jigsaws are divided into ordinary and artistic. The difference between them is in the location of the file: in a regular file, the file is located vertically, but in an artistic one, the role of the file is played by a steel blade. A regular jigsaw can be used to cut through thick plywood to make a headboard or other furniture. Artistic can be cut complex elements, letters, puzzle pieces.

Cutting blades are varied for each type of jigsaw, and they need to be selected according to the material with which you are working.

How to cut out of plywood with a jigsaw?

Before cutting 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 cutting, the veneer will begin to peel, which will lead to damage to 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 that some part of the blade is bent, the file should be replaced.

When sawing plywood with a jigsaw, you should, if possible, place the main cutting lines along the veneer fibers.

This will promote clean cut edges. When working with a hand jigsaw It is easier to cut across the grain. This will not protect against chips, but there will be less chance that the file will get pinched or it will move along the chip away from the intended line.

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

To cut a circle with a jigsaw, a blade is inserted into the hole. Free end hand model is secured back in place using a clamp or mounting screw. The workpiece is pressed against the workbench with clamps, and the cut is made according to the transferred line. When the circle is closed, the central element is separated from the sheet and the edges are processed with sandpaper or a file.

Before cutting with a jigsaw with an electric motor, you need to install a narrow file on it. There is a special improvement for this tool called a circle cutter, it is installed in the center and work begins. When working, do not put pressure on the tool; this does not contribute to faster movement. As a result of the pressure, the jigsaw blade and even its fasteners can bend and break. If the circle that needs to be cut has a small radius, it is better to do the work in several approaches, since sharp turns can break and bend the blade.

A jigsaw is a well-known hand-type tool designed for cutting patterns on various surfaces. In terms of its importance, it is as important as a drill or hammer drill.

A jigsaw is used for sawing various types of materials (wood, metal, etc.).

They can make straight and curved openings in wood of any species and other non-natural materials, as well as precise cuts of geometric shapes with complex trajectories. The tips and recommendations listed here will help you figure out how to cut a circle with a jigsaw.

Properties of metalworking tools

The jigsaw is intended for household and professional needs. Devices of the first type are characterized by low power and are designed for work in small volumes. The purpose of using special equipment is the professional orientation of the tool, its productivity and a long period of work.

Usually household appliances have a standard set of functions:

  • frequency of moves;
  • method of fixing a sheet for cutting;
  • pendulum type movement;
  • turning the saw.

A jigsaw is used for finishing surfaces, cutting out uneven edges, internal holes, and making furniture. The processed material is securely fixed to the base. Marks are made on it in advance, then the holes are sawed. Rotational vibrations of the shaft are converted into translational movements. The saw is fixed on the rod, its quality determines the life of the product. When choosing a device, preference should be given to round shapes and thickened stems.

The jigsaw has such positive qualities as:

  1. Cutting holes in any samples.
  2. A simple device allows you to quickly replace saws.
  3. Possibility to make round or rectangular cuts.
  4. Ease of use.
  5. Does not require special knowledge or skills.
  6. The presence of a significant number of saws with different step limits of action and tooth shapes makes it possible to carry out various types work in conditions of one device.
  7. Reliable fixation of the cut sample allows any distance from the edge of the product.
  8. Device universal action allows you to cut to any depth.
  9. During the work, the material is practically not damaged.

Disadvantages:

  1. The shortened movement of the blade ensures slower operation of the device.
  2. Possibility of injury.
  3. Possibility of cord failure.
  4. Checking the battery charge level.

The jigsaw has a built-in protection system, pneumatics and an electric drive.

The new products being released are equipped with improved functions: reducing the number of vibrations, improving productivity indicators, and equipping the device with convenient functions. Depending on the method of fixing the cutting part, saws are:

  • with holes;
  • with a cross-shaped element;
  • with a smooth base.

In some ways, a jigsaw can replace a router, a hand saw, a circular saw, a chain saw, or a corner grinder. The tool is necessary in any household; it allows you to carry out wood carving.

The current supplied to the device from the network gives an impulse to the motor, setting it in motion. Together with the gearbox, it transmits the impulse to the gear, which secures the rod. The circular action of the shaft is modified into the movement of the working element of a reciprocating nature, moving up and down. The saws are fixed using screws or clamping mechanisms. Such fasteners help to change the canvas in a short time.

Rules for working with a jigsaw

To understand how to properly saw a circle in wood, it is important to study the features. This carpentry tool helps to cut out ovals, wavy patterns, figures with uneven outlines, non-standard carved boxes, shelves with end-to-end patterns. To ensure that interaction with a jigsaw is organized and safe, it is important to adhere to the following rules:

In order for work with a jigsaw to proceed quickly and safely, do not forget to fix the product before work.

  1. To avoid inconvenience, special stands should be prepared during work. A slot is made up to the middle of the support, somewhat reminiscent of a lock hole.
  2. The stand is fixed with clamps or screws to the workbench.
  3. At the time of work, you need to sit down, position the file strictly vertically relative to the floor and perpendicular to the surface.
  4. The workpiece is placed in the middle of the stand, holding it with your left hand; you can saw the plywood with your right hand. The location of the cuts should be in the middle part of the support hole.
  5. The tool does not tolerate strong pressure: just a small touch and gradual movement up and down, and it will begin to work effectively.

Attributes:

  • pencil;
  • drill;
  • drill;
  • jigsaw

Often, when repairing or installing various wooden products needs to be drilled perfectly round hole. In this article we will try to highlight all the ways in which such a hole can be cut. Options with the use of special tools, as well as without them, will be considered.

How to cut plywood

A hacksaw with a very narrow blade, a jigsaw, a drill saw and a round file are those hand tools, which can be used to cut along a curve.

It is the narrow blade that provides maneuverability to the hacksaw, but for the same reason it is extremely difficult to operate. Must have a firm hand and an attentive eye to prevent deviations from the markings. However, do not try to work quickly. On the contrary, it is better to advance in small spurts. This will help you hold the saw handle more confidently and guide it exactly along the given line.

It is better to cut out small round or oval holes and “narrow” curves using special tools - a drill saw and a round file, which can also be used to clean out curves.

However, the most suitable tool for cutting rounded parts and holes is an electric hacksaw. Its advantage is not only that it saves energy and time. The included set of interchangeable blades with different teeth allows you to choose a blade for sawing almost any type of workpiece, be it wood, plywood or chipboard. In other words, an electric hacksaw can rightfully be called a universal tool.

Round corners of furniture

You can even get injured by hitting a sharp corner of the table. Therefore, we recommend cutting corners where possible. U homemade furniture they need to be rounded off from the very beginning.

Cutting circles and curved lines is no more difficult than making an absolutely straight cut on a workpiece, but under one condition: in your hands the right tool and you are good at it.

Mark missing parts

It may happen that the holes that you drilled to insert a narrow blade of a hand or electric hacksaw will end up on useful areas To avoid such errors, you should mark all missing parts of the workpiece with shading.

What is suitable for the template

You can make a circle on a workpiece not only with a compass. For this purpose Any will do an object of a similar shape. This could be a pan, plate, cup or bowl. However, when starting work related to the repair of furniture or some piece of furniture, calculate in advance the need for parts with rounded contours or with round holes. It may be enough to make only minor changes to the design.

Instead of a compass

A school compass can also be useful in a home workshop, but its range of action is small. What if you need to draw a circle of large diameter?

An easy way is to do this with string, a nail and a pencil. The nail is carefully driven into the workpiece, the rope is secured to it at one end, and a pin is secured to the other end. The length of the rope determines the radius of the circle being drawn. The only condition— along the entire path of the pencil, the rope should be taut. Then the distance from the center (nail) to the circle in all sections of the marking will be the same.

Strip of cardboard or slats

No less simple, but more reliable way- use a strip of cardboard or, even better, a wooden plank instead of a rope. Drill two holes in this bar (strip) - one, smaller, for a nail, the other, larger, for a pencil. The distance between their tips should correspond to the radius of the desired circle. All that remains is to install the nail in the right place and rotate the bar around its axis.

Two sharpened nails and wooden plank or a strip of thick cardboard can replace a compass.

How to draw ellipses

An ellipse is a rather complex shape, but to draw it on paper, you only need two thumbtacks, a piece of string and a sharpened pencil.

Attach two buttons to the surface of the workpiece at some distance from each other. Take a piece of rope, tie both ends into a knot and hook the rope onto the button heads. Now use a pencil to draw a line that allows you to describe taut rope. You can change the shape of the ellipse at your discretion.

The distance between the two focal points of the ellipse is indicated by buttons. If you guide a pencil within the boundaries assigned to it by a rope, then the outline of an ellipse will appear on the paper.

The ellipse shape can be larger or smaller, thicker or narrower, depending on the distance between the buttons and the length of the rope.

Templates

Shot glasses, cups, plates, pots or baking dishes - in any household there are many round-shaped objects that can be used to mark a circle. If you are making something and decide to give your product a rounded shape, then first look to see if there is a suitable template among the household utensils. To be sure, select a few items and take them to the workshop. There you can immediately try them on the workpiece and determine what is most suitable. With some practice, you will be able to make rounded lines from several round objects with different radii. Arcs of a circle can be drawn sequentially, or bridges-transitions can be made between individual arcs.

Preliminary drawing

Before attempting to draw a curve on a piece, design it on a large piece of paper or piece corrugated cardboard. Only after the result is satisfactory in all respects can you cut out a template from paper and make markings on it on the workpiece.

You can draw circles and fragments of a circle using a cup or plate by simply tracing them with a pencil.

Inserting a sink according to a template

Washing is one of the essential elements kitchen equipment. If you decide to cut your sink into your kitchen worktop yourself, the first thing you need to do is prepare an exact template.

First, transfer the outer outline of the shell onto a thick sheet of paper. Next, measure the width of its sides, which will rest on the tabletop. Usually this is 2-3 cm. Now step back from the outline drawn on the paper, inward by the width of the side and draw a parallel line. This will be the cutting line.

When applying markings, make sure that the position of the template itself on the plate is correct. Of course, if all the corners of the sink are symmetrical, then nothing bad will happen if, according to the markings, it appears to be in a mirror image. But if the sink has the shape of a trapezoid and the roundings at the front corners differ from the roundings at the back, then under no circumstances confuse the front and back parts.

Using a similar pattern, make templates and cut out holes for the devices. wall lighting or for loudspeaker mounted on wooden panels.

The line drawn around the sink is auxiliary. The second, drawn parallel closer to the center, is the sawing line.

Electric hacksaw

If you need to cut a round-shaped part and saw a round hole in the workpiece, then an electric hacksaw is the most suitable tool. With its help, you will save effort and time, since such a saw has great advantages over a manual one. Thus, the blade of the electric hacksaw is narrower, which provides increased maneuverability. Further, it has replaceable blades with different teeth, which allows you to process workpieces of any type, that is, wood, plywood, chipboard (it is no coincidence that the tool is also called a jigsaw).

To cut a section inside the workpiece, a hole is first drilled for a hand saw. But if you have an electric hacksaw, then this is not necessary. The tool is brought to the workpiece with a slight tilt forward and turned on in this position. The saw will cut the hole itself. Just don’t put too much pressure on the body - this can lead to breakage of the saw blade.

Lead in a circle

This device, simple in design, makes cutting out round holes or arcs much easier. It is enough to mark the center of the circle on the workpiece, fasten the device along the mark and connect the rod coming from it with an electric hacksaw. The divisions on the rod help set the saw blade at the required distance from the center of the circle. As a result, without preliminary marking you can cut a circle or saw an arc with a radius from 5 to 20 cm.

The device (more precisely, its “sole”) is attached to the surface of the workpiece with screws. They should be well tightened. If the fastening is not rigid and starts to wobble, then smooth circle it won't work.

Suitable for lefties too

Left-handers can also use the device, since the guide rod is attached to the movable unit both on the left and on the right. So cut at your own discretion - clockwise or counterclockwise.

Using such a device, you can cut a round hole with a diameter of 10 to 40 cm in the workpiece without preliminary marking.

Jigsaw

When cutting holes or curves in small workpieces, sometimes you can’t do without a jigsaw. Replaceable blades with teeth of different shapes and locations allow you to work with wood of different densities. However, it should be taken into account that the depth of the cut is limited by the arc of the jigsaw, that is, the saw blade will not be able to move further than 30 cm from the edge of the workpiece.

Very thin, narrow saw blades can be easily damaged if the jigsaw is used incorrectly. The saw must be operated with careful, methodical movements. The main thing is to prevent the canvas from skewing. Otherwise, small and light workpieces will begin to move with the saw, which may ultimately lead to the blade bursting.

The thinnest jigsaw blade will “master” the narrowest curve, but only in small workpieces, since the advancement of the blade is limited by the arc of the jigsaw.

Drill saw

Neither a hand saw nor an electric hacksaw will help if you need to cut a small hole in the workpiece - less than 10 cm in diameter. A jigsaw may also be useless if the workpiece is large. In this case, the most suitable tool is a drill saw. With its tip it bites into the wood like a drill and thus makes a “starting” hole for further cutting. Externally, the saw is similar to a round file with the difference that its shaft is surrounded by a spiral around the cutting edge.

Drill saws are available with replaceable nozzles of various diameters, designed for processing both soft and hard wood, as well as a variety of materials made from it.

The working body of a drill saw is a metal rod with a cutting edge, like a gimlet, and cutting edge, which goes around the rod in a spiral.

This is what the narrowest one looks like hand saws. Thanks to the fastening unit, the blades in the hacksaw can be changed depending on the nature of the material being processed.

Drill attachment

One of the most popular and convenient options The hole is cut using a special attachment on the drill. It is made in the form of a crown comb and has a rounded shape. With this attachment, cutting holes occurs quickly, and they turn out quite smooth.

drill bit for holes

There are nozzles different diameters, which allows you to cut a hole of the required diameter. If you have already prepared a hole, we can advise you to try your hand at options trading.

Drill

Cut big hole You can also use a drill. To do this, it is necessary to pre-mark the outline of the hole to be drilled. Next, use a small drill to drill along the contour prepared in advance, through holes. Next, using a jigsaw or a very sharp knife, we cut off the holes, thereby connecting the holes. After which you can smooth the circle using sandpaper of various grain sizes.

Chisel

You can also cut the required hole using a chisel. It is enough to remove the wood layer by layer along the contour. This option is the least suitable for interior decoration. The hole must be smooth, which cannot be achieved by using materials at hand and unsuitable for the job. The best option would be to use a drill bit. The hole is even and has smooth edges.

Thus, to summarize, it becomes clear that you need to choose a tool for cutting a hole based on your goals. If high-quality cutting is required, then without special tool can't get by.

Fans of all kinds of handicrafts should definitely pay attention to this type of decorative and applied art, such as plywood cutting. This method can be used to make all kinds of figures, patterns and other decorative elements.

Moreover, mastering such a technique is quite simple, the only thing is that you first need to familiarize yourself with its main nuances, which we will do below.

What you need for cutting

First of all, let's consider what tool you will need for this. It should be said right away that expensive equipment for cutting out plywood is not required. Therefore, anyone can do this kind of work.

The only thing you need to prepare is the following tool:

  • jigsaw;
  • electric drill and brace;
  • scissors;
  • cardboard templates;
  • files.

In the photo - a manual jigsaw

In addition, you will need various consumables, such as:

  • sandpaper for sanding cut areas;
  • tracing paper;
  • pencils;
  • glue;
  • acrylic paints, etc.

In addition, it is necessary to prepare workplace. Since working with any wood materials implies the presence of sawdust and unnecessary trimmings; it is advisable to set up a workplace not in a living space, but, for example, in a garage.

The workplace itself is a table. It is advisable to attach a jigsaw stand to it, which can be made from a plank. It is also necessary to ensure good local lighting of the workplace.

Cutting Features

Material selection

As you know, plywood is multilayer material, which consists of several layers of veneer. This makes it great for creativity.

The only thing is that you need to choose the right type of plywood. To do this, you need to pay attention to the following parameters:

Options Optimal material type
Thickness To cut out plywood yourself, you should not use sheets that are too thick, as this will complicate the work. At the same time, the material must be strong enough. Therefore, the optimal thickness is 8 mm.
Brand The brand indicates the type of adhesive used to glue the veneer together.

It depends on things like:

  • material price;
  • its moisture resistance;
  • environmental friendliness.

To make decor that will be used in a residential area, you should use environmentally friendly brands of plywood, for example, FC. If the product is made for outdoor use, it is necessary to use moisture-resistant sheets, such as FSF.

Variety Determines the quality of the material, and therefore its appearance. Accordingly, for creativity it is necessary to use the sheets of the most high grades so that there are no visible defects on them.
Wood type For cutting are the best option plywood sheets from coniferous species, since they are easy to machine and at the same time have an attractive texture. True, in cases where a weak texture is required, you can use birch plywood.

What to cut

As a rule, people who encounter this kind of work for the first time are interested in what can be cut out of plywood?

There are a lot of options - these could be:

  • patterns for decorating furniture or other interior elements;
  • panel on the wall;
  • decorative inscriptions;
  • all kinds of figures, toys for children, etc.

Advice! You can also make functional carved objects from plywood, for example, boxes, candlesticks, napkin stands, lamps and much more.

Of course, you should start by cutting out the most simple products, to “get your hand.” After gaining experience, you can take on work of any complexity.

Cutting process

After preparing the workplace and materials, we proceed directly to the cutting itself.

Instructions for doing this work look like this:

  1. First of all, you need to make an image of the future product. You can make them yourself, or find them on the Internet and print them. It must be said that templates must be prepared even before cutting out words from plywood with simple contours, as this will greatly simplify the work and improve its quality.

You can also prepare templates of simple geometric shapes in advance different sizes to, for example, quickly cut a circle or square from plywood;

  1. then the images should be transferred to cardboard, for example, using carbon paper;
  2. now you need to cut out templates from cardboard;
  3. Next, the prepared templates need to be placed on plywood sheet and circle with a pencil. If the design is large enough, it can be fixed with tape or even glue;
  4. Now let's start cutting. If you need to beautifully cut the edge of plywood, giving it smooth shapes, you can use a jigsaw. Thinner and difficult work, for example, small openwork patterns should be cut out with a hand jigsaw.

To make internal cuts, you must first drill a hole. Depending on the fineness of the work, you can use an electric drill or a brace for this;

  1. After completing the cutting, it is necessary to treat the cut areas with sandpaper. To correct the lines, you can use needle files;
  2. then the product needs to be sanded. If it consists of several parts, they must be glued together, for example, with PVA or wood glue.

Advice! Novice craftsmen often ask experts how to cut an even circle from plywood? In fact, there are no secrets in this operation, the main thing is to correctly apply the circle to the material using a template or compass, and then carefully and slowly cut it out with a jigsaw.

This completes the cutting process. Now the product can be decorated - painted with paints, applied with a burner, or simply varnished.

Advice! Word templates for cutting out of plywood can be prepared in text editor, such as Word. This will allow you to choose the most suitable size and font.

Here, in fact, are all the main nuances of this work.

Conclusion

Cutting out plywood with a jigsaw is much more a simple task than, for example, wood carving. Therefore, in order to achieve good results It won't take years to master the skill. You just need to do the work carefully, adhering to the recommendations outlined above.
