How to cut a window in a piece of plywood
Sometimes the boards need to be sawn inside, cutting out the so-called “window” from the common part. But this must also be done with the observance of special rules. First you need to mark a point at the cut point. It should line up with the corner and middle portions of the circular disc. During the whole process, the marked cutting line should be slightly to the side.
The main thing is to smoothly lower the circular disc into the plywood so that a return blow does not occur. Further, at full power, you can directly cut. Completion of work can only be carried out when the tool has come to a complete stop.
How to cut a long board in half
The circular saw also handles very long materials. For this it is necessary to carefully prepare the workplace. It is required either to put the slats under the board, or to saw on the trestles. The technology is almost the same.
The bottom line is to allow the end of the board to fall slightly during the cut, without losing the position of the circular saw. At the end of the work, the piece to be sawn off will simply fall to the floor, which will be the end result. The main thing is that the board does not fall off before it is completely cut.
Make a cut without stopping
It is advisable not to stop while cutting wooden parts. The circular saw should run smoothly through the material and not be interrupted. Otherwise, bumps and cuts will remain on the boards, which will interfere with the further use of the tree.
Movements should be smooth and soft so that the disc does not become dull and runs smoothly on the board. It is also advisable to check the length of the cord in advance. If it does not reach, use an extension cord. Otherwise, the tree will also be cut unevenly.
Sticky tape for sawing
In order to avoid chips on the material, and the veneer retains its original appearance, you can use sticky tape or, in another way, molar tape. It will not leave marks on the wooden board, and will also protect the tree from visible mechanical damage.
The tape is attached in the place where the cut will be made. Next, you should carefully cut the board, after which you can remove the molar tape. It can be dismantled only to the side of the cut and at right angles. The main thing is not to pull the tape up so that the plywood does not delaminate.
5 tips on how to properly cut wood with a circular saw
The circular saw is a versatile tool for cutting all kinds of parts and elements. To carve wood with this tool, you need to familiarize yourself with some rules that will facilitate the work and help you safely saw the object into small parts. 5 tips on how to properly cut wood with a circular saw will greatly simplify the task of repairing.
How to cut a small piece of board without the goats
You can easily use a circular saw to cut small pieces. To do this, you can not even use the goats, but simply put the board with its edge on the toe of the leg, the shin will serve as a support. Next, it is worth drawing a cutting line, aligning the tool along it and making a cut.
The main thing is to maintain a safe distance from the incision to the leg. It must be more than 30 centimeters. At the end, the element to be sawn will simply fall to the floor, where the client should lie in advance under the sawdust.
The circular saw is suitable for cutting elements of any complexity and shape. It is necessary to follow the rules and requirements for safety, so as not to spoil the material and not injure yourself. Therefore, these tips will help you avoid mistakes when sawing wooden planks with a circular saw. They must be adhered to, then the work will be done efficiently and without defects.

How to increase the service life
The relay provides a smooth start and stop of the circular, thereby reducing inrush currents. This protects the network from short-term load surges and reduces wear on the electric motor. Thus, the actual service life is increased by 2-3 years. The functionality of the protective relays is different, but most of them protect against frequent network problems:
- “Surges” of voltage, if there is imbalance on one of the phases;
- Phase loss;
- A sharp increase in power due to a breakdown;
- Damage or breakdown of insulation of live parts;
- Short circuit of the stator winding to ground, during operation.
By installing a protection relay or one of the frequency converters, you protect the motor from failure due to the occurrence of one of the problems, which happens quite often. In such cases, the winding usually burns out, and it is difficult and expensive to replace it. It’s easier to put a protective relay, and not risk it.
Instead, a soft starter (SCP) is also suitable, providing a smooth start of the electric motor. By changing the frequency of the sinusoid, the revolutions smoothly increase to nominal and also smoothly decrease after switching off.
Proceeding from the fact that the UPP costs from 50, it is inappropriate to put it on old and cheap Chinese engines for the same 50. Nevertheless, this is an excellent solution for more valuable analogues, which will double their “lifespan”.
When you turn on the circular saw, the network load will increase by 1-1.5 kW, therefore the wiring and the outlet itself must also be protected.
What can be done with a circular saw
The principle of operation of this unit is based on the rotation of the cutting disc by an electric motor. The saw design is presented in two versions: manual or stationary. An important difference between these two versions is that the force from the engine to the disk in the stationary model is transmitted through the belt, while in the manual model the disk itself is fixed on the shaft. The saw can cut wood both along the fibers and across them, cut out a quarter. The tool can be used to saw off soft metal, plastic, if you use special discs.
What is a circular saw for?
It is designed to cut softwood and hardwood boards with a moisture content of no more than 50% and a thickness of no more than 64 mm. It is allowed to cut plywood, aerated concrete, chipboard, asbestos-cement and cement-particle boards.
Circular saw device
A really useful tool, the circular has a fairly simple design. Its main nodes:
- bed. a frame on which the main units are mounted;
- table top with a slot for a disc;
- engine with a rotation transmission system;
- cutting tool, toothed disc.
Optionally, the device can be supplemented with a pusher, which provides a translational advance of the workpiece to the disc, and various lifting mechanisms that regulate the cutting depth.
The principle of operation of a circular saw (circular) is that the rotation of the electric motor shaft is transmitted to the cutting tool, a disk with sharply sharpened teeth. The center of the disc is located below the level of the table top, only its segment is removed from it. The workpiece is fed to the rotating disc, the teeth bite into the wood, creating an even cut.
This design has two main disadvantages:
- To adjust the accuracy of sawing wood with a broach machine, you need to use wood trimmings. After that, the traction can be firmly fixed and work normally;
- Such a self-made installation with a broach when cutting pipes and working on metal makes a lot of noise, which can negatively affect at least the mood of your neighbors.
How to use a circular saw
How to work with the tool correctly:
- When working, do not use clamps, vices, or other methods of rigidly securing the workpiece. It is unacceptable to hold it with your hands or body.
- Do not overload the tool by doing work that is not intended for it.
- If the on / off key is broken, do not use the tool.
- When changing accessories, making adjustments and other work, the tool must be disconnected from the power supply.
- Storage of the tool should be done in places that are hard to reach for children and pets.
- Remember to periodically service your tool.
Cross cut features
Cross-cut is used only for creating firewood or interior elements. The work is carried out according to several principles:
- Before carrying out work, the log is placed in a horizontal position on supports. Its height should be 0.5 m.
- After that, it is necessary to completely clean the log from bark.
- At the next stage, it is necessary to make marks on the entire log, located at an equal distance from each other.
- Then, according to the created marks, you can cut.
No special tools required for cross-cutting.

Hacksaw. simplicity and safety
A hacksaw is a simple tool that is quite suitable for work. And although the cutting speed is low, and considerable physical effort is required, but for home conditions such a saw is the most acceptable option.
It is not difficult to cut correctly with a hacksaw on wood. The main condition for a high-quality cut of the material is to make the correct cut. To simplify the task, you can use a regular flat bar, which is used as a guide.
Often the question arises of how to smoothly saw off a board with a hacksaw at an angle. For this, a special carpentry device is used. a miter box. over, it will help not only to make a cut at the desired angle, but also allow any beginner to cut the board exactly.
Top 3 Circular Saw Projects || 3 Best Circular Saw Ideas
You can also cut off a bar with a hacksaw. The only problem when working with such a workpiece is that you have to make a lot of effort.
The last option is to use an angle grinder with an installed wheel with teeth for work. But since the “grinder” is not intended for cutting wood, this method can be used only as a last resort: attempts to cut the board can result in serious consequences. It’s better to use a hacksaw. it’s time consuming, but safe.

How to cut a log into planks with your own hands and not spoil the materials
It should be noted that the performance of the nozzle can be changed, since the speed of rotation of the shaft depends on the size of the pulleys.
Types of working attachments
The choice of attachments for work depends on the volume and type of work being done. The following devices are used with a chainsaw:
- drum debarker, which is necessary for removing bark from logs;
- lightweight nozzle for sawing logs;
- standard nozzle used for making boards.
Features of sawing logs when using a chainsaw
It is quite simple to create additional equipment for sawing logs:
- To create a support, a frame is used, which can be created from the legs of a school desk. The most suitable are pipes with a square section of 20 × 20 mm.
- When constructing the frame, it is necessary to create 2 clamps, and fix the cross member at one end. This element should have holes for the tie bolts. A protrusion for the tire is created in the middle.
- In order to cut a log lengthwise, it is necessary to design a support frame, the width of which should be at least 8 cm in length.
- For the convenience of work, a handle should be welded to the frame.
- Before carrying out work, it is necessary to carefully check whether the frame is securely attached to the tire.
Using a homemade tool is easy enough. Before sawing, you need to install 2 trestles. they will be used as a support for the log. In addition, a metal rail or flat board is prepared, which will serve as a guiding element.
How to cut a board straight
Beams and planks are common materials used in house construction. In the absence of funds for finished materials, you can make them yourself using a chainsaw. Before you cut a log into planks with your own hands, you should learn more about the features of this process.
Sawing along the grain.
But discs with a small number of teeth will provide high productivity, but the cut quality will also be worse.
Now about how to cut straight with a circular saw. One of the conditions for high-quality performance of work is reliable fixation of the workpiece. If the material is weakly fixed, then when cutting the board may “go”, and the cut will be uneven.
If the circular saw is hand-held, then all work should be performed on a workbench equipped with stops and guides for the workpieces. Such a device can be made independently, taking any table as a basis.
It is important to set the cutting depth correctly before starting to cut. Some hand saws have an adjustable side guide that can be used to rip through the material. If there is no such device, then use the same workbench.
convenient in terms of work is the table circular, which is already equipped with everything you need. guides, clamps. Often, such equipment allows you to make and cut workpieces at an angle.
During the sawing process, it is important not to exceed the force on the tool, otherwise the cut quality will be low, the increased load on the saw will lead to a rapid dullness of the cutting blade.
Do not forget about safety precautions when using such equipment. Work should be carried out only after checking the saw’s serviceability and the correct fastening of the workpiece. Also, do not neglect protective equipment. masks, glasses.
Features of cutting porcelain stoneware
It should be noted that cutting a very dense and hard porcelain stoneware slab is sometimes even easier at home than in the case of ceramic tiles. Those who don’t believe can try to cut overheated ceramics made on old Soviet or Chinese equipment at home. In comparison, cutting porcelain tiles does not look so problematic.
It is quite possible to cut porcelain stoneware without chips, although some masters argue that it is impossible to achieve this in principle. If this were indeed the case, then most of the walls and steps tiled with porcelain stoneware tiles would be with wide seams, curves and unattractive.
It’s not even about the hardness of porcelain stoneware. The technology for the manufacture of artificial granite is such that as a result of pressing and deep firing, a material is obtained practically without internal stresses, and this is the guarantee of a high quality cutting line.
In order to accurately and accurately cut porcelain stoneware at home, only two conditions must be met:
- Choose the right cutting mode, ensure constant and uniform pressure with the cutting tool on the cutting line of porcelain stoneware;
- Choose the right tool for your specific cutting conditions.
It is clear that at home the possibilities of cutting the material are significantly limited, but even in an apartment it is quite possible to cut porcelain stoneware without a tile cutter, although initially the amount of dust generated when working with electric machines is frightening.
How to cut porcelain stoneware with a glass cutter
The technology of cutting tile material using a manual glass cutter is not much different from the previous method. The only differences are that instead of a carriage moving along the guides, you have to cut porcelain stoneware with a small tool held in your hand.
In fact, this is ideal if you want to cut material at home. Instead of a frame fixture, a regular table, a metal ruler and the glass cutter itself are used. In order to cut porcelain stoneware, it is enough to lay a ruler on the marking line and draw a diamond along the cut line.
To break the material, the tiles are laid on the table so that the scratch line coincides with the edge of the table top, pressed on top with a board and with a sharp movement break the material into two halves. For home conditions, there is no simpler way, but in order to master the technique, you need to practice cutting on the waste of porcelain stoneware or glass.
The advantage of this method is the simplicity and the minimum amount of equipment required. It is easier to store a manual glass cutter with a diamond at home than a tile cutter. The disadvantage of this method is that it is necessary to learn how to draw a line with a diamond along the markings at a constant speed, and most importantly, to do it continuously, in one motion, while accurately measuring the force applied to the surface of porcelain stoneware.
In addition, it is very difficult to cut material with a glass cutter without chips, therefore, if possible, it is best to use a diamond rather than a carbide roller.
Professional advice
Oddly enough, but the greatest number of problems arise not even with the drive or the tool used to process porcelain stoneware, but directly with the diamond disc. The main complaint about the diamond is the rapid loss of cutting ability. As a result, with an increase in feed and force, the edge of the wheel heats up and begins to lose diamond powder. If you try to cut at home in this mode for at least 10-20 seconds, then nothing will remain of an expensive disc.
In this case, before each cut, the edge is cleaned and restored; at home, this can be done on an ordinary red brick by performing several small cuts. This removes soft material adhering to the diamond strip.
How to cut porcelain stoneware tiles with a tile cutter
A tabletop or floor device for cutting all types of tiles is a small frame with rails installed at the top and a carriage with a carbide head. The carriage is driven by a lever or electric drive. Simple and convenient mechanism at home.
At home, the tile cutter turns out to be the most affordable tool for cutting porcelain stoneware.
Before cutting the porcelain stoneware, the tiles are laid on the frame and fixed with plastic or metal stops. This is to ensure that the material does not shift during the cut. Next, we bring the head to the edge of the tile until it touches and push the lever away from you, the carriage with a diamond or carbide tip evenly passes over the surface of the tile, leaving a deep scratch behind.
It remains only to break the porcelain stoneware into two parts with a slight but sharp movement. One of the ways to cut porcelain stoneware with a manual tile cutter is shown on
- It is very easy and comfortable to cut porcelain stoneware at home, you can master the cutting technique even with minimal experience and qualifications;
- A minimum amount of dust is formed, which is very valuable at home, especially if you plan to lay porcelain stoneware tiles on a small area of the floor or wall.
An electric tile cutter resembles a circular saw for processing and sawing wood in its structure. In order to cut porcelain stoneware, you just need to set the size of the cut strip, after which you can cut in unlimited quantities.
Home compact version of the electric tile cutter
The disadvantages of the device include the fact that only material of a certain shape and size can be cut, for example, it is very difficult to cut a thin strip of porcelain stoneware or make an incision of a non-standard, curved shape.
A thin strip of porcelain stoneware is easier to cut with a grinder
How to cut porcelain stoneware with a jigsaw
Quite an unusual way of sawing porcelain stoneware slabs. Using an electric or hand jigsaw to cut very dense and hard material always raises some doubts among beginners. Nevertheless, it is quite possible to cut ceramics and porcelain stoneware with a jigsaw even at home, but only if certain requirements are met:
- The tool must be prepared for cutting porcelain stoneware. A thin, necessarily soft material is glued to the sole, you can use paper or rubber. This is done in order not to scratch or damage the front surface of the plate;
- The second step is to turn off the pendulum vibration-movement on the hacksaw blade feed mechanism, otherwise the saw will cut chipped into porcelain stoneware;
- A special type of diamond-coated hacksaw blade is used for sawing tiles.
In addition, the slab itself must be securely fixed on the countertop with clamps, and a rubber strip must be placed under the porcelain stoneware to reduce vibrations. The method for cutting porcelain stoneware is quite simple and does not require special skills, ideal for use at home. It is valuable that the curly cutting of porcelain stoneware is very easy to perform with a jigsaw.
You can also cut tiles with a hand jigsaw, sometimes there is simply no other tool at home, however, it will take several times more time, but it is possible to get a very accurate and high-quality cut. In this case, the side edges of the hacksaw blade are ground, and emery powder is fed into the seam during the sawing process.
Curved cutting of porcelain stoneware
It is believed that this method is the cleanest of all mechanized options, which is especially important if you have to work at home, without a hood and vacuum cleaner.
Cutting porcelain stoneware tiles at home
Anyone who prefers to make repairs or do small jobs with their own hands must have had to cut porcelain stoneware at home. In the first trials, cutting of porcelain stoneware tiles is more difficult than in the case of cutting tiles. It turns out a lot of scrap, but in general, the process itself is not much different from working with high-quality ceramic tiles.
The cutting line should be marked with an allowance for finishing
How to cut porcelain stoneware tiles at home
In terms of technology, there are two main ways to cut porcelain stoneware. To do this, you can use various tools and devices, but, regardless of the number and type of technical equipment, porcelain stoneware is still cut in two ways:
- Mechanical sawing of a porcelain stoneware array. In this case, the cutting line is sampled with an abrasive tool;
- Injection method. A deep scratch is cut on the surface of the porcelain stoneware along the future dividing line. Further, a bending or shear force must be applied to the porcelain stoneware, and the tile splits exactly according to the markings.
At home, you can use both methods, depending on the tool available, the amount of work and the thickness of the material. In addition, the complexity of the cutting line configuration has to be taken into account. For example, if you want to cut a tile that is large enough in size at home, which simply does not fit into a tile cutter, then you will need to look for a cutting diamond wheel and a grinder. For cutting at home, this is one of the most reliable ways.
Having laid the tiles on a sheet of drywall, you can cut the porcelain stoneware with a grinder in almost any trajectory, it is only important to take your time and evenly press the edge of the disc to the surface of the porcelain stoneware. Otherwise, you can easily overheat the tile at the cut point, which will lead to the formation of a pin.
How to use a circular saw
How to work with the tool correctly:
- When working, do not use clamps, vices, or other methods of rigidly securing the workpiece. It is unacceptable to hold it with your hands or body.
- Do not overload the tool by doing work that is not intended for it.
- If the on / off key is broken, do not use the tool.
- When changing accessories, making adjustments and other work, the tool must be disconnected from the power supply.
- Storage of the tool should be done in places that are hard to reach for children and pets.
- Remember to periodically service your tool.
Setting up the circular saw
Before starting work, you should:
- put the disc;
- make sure that it is securely fastened;
- make sure that the protective cover opens freely and returns to its original position when the handle is released;
- check the correct installation of the riving knife;
- make sure that the saw is working properly by holding it in the ON mode for 10 seconds without load.
It is quite easy to adjust the saw before starting work. This requires:
- Adjust the position of the guide slot on the table and disc using a caliper, aligning the guide slots on the blade. When checking the tooth in the front and back of the blade, the difference should not exceed 0.05 mm
- Check the parallel stop with a groove or slot. Here, the offset should also not be more than 0.05 mm.
- Align the riving knife with the blade so that it is in line with the blade. In case of mismatch, a more accurate adjustment is achieved by rotating the washers

Circular and circular saws as indispensable helpers in your farm. How to saw and tune the tool?
The forerunners of modern automatic saws were tools made of stone, bones, on which jags were applied from one edge. The beginning of this instrument was laid in the fourth millennium BC. They are used both in household work and in the creation of various works of art.
Then, stone and bone were replaced by copper, iron, steel. The first power saws appeared in Germany in the XXIV century. Electric saws became widespread only in the 20th century.
What is a circular saw for?
It is designed to cut softwood and hardwood boards with a moisture content of no more than 50% and a thickness of no more than 64 mm. It is allowed to cut plywood, aerated concrete, chipboard, asbestos-cement and cement-particle boards.
A circular saw. How to cut it
The main stages of working with the tool:
- Set the minimum depth of cut by adjusting the blade downward.
- Fit the guide to the size of the part by measuring the length from the edge of the blade to the edge of the foot of the saw. Mark up the material.
- Make the initial cut 3-5 mm.
- Continue sawing without stopping all the way through the blade.
- Use duct tape at the cut to avoid chipping.
