Circular saws. the most important things in a nutshell
For carpenters, plank and bar are the most common blanks from which to later produce crafts and wood products.
And the first thing the material is subjected to is sawing into sections of the required length.
In this case, you should know how to evenly saw off the board, because improper performance of this operation can spoil the workpiece or significantly affect the appearance, and not for the better.

And the first thing the material is cut to length.
In this case you should know how to saw a board evenly, because the wrong performance of this operation can spoil the workpiece or significantly affect the appearance, and not for the better.
At large enterprises there is no problem how to saw off a bar or a board evenly. Any serious enterprise has high-precision equipment that performs this type of work.
At home we have to make do with what we have on hand.
In this case you need to be able to use the tool or equipment correctly to cut the board correctly, and the cut should be without flaws.
Note that many companies that sell boards and logs, provide services for their cutting. And they use the same specialized equipment, so the purchased material will be cut qualitatively. But it is not always possible to use such a service, and it often happens that it is necessary to saw only one workpiece.
Cutting a board at home
Cutting a board at home is possible with tools and equipment such as:
Each of these options has its own specifics, which is important to consider before starting work, that is, you need to know how to saw a log or board with this or that tool so that the quality of the cut was acceptable.
Circular saw. high productivity and convenience of work
The circular saw is the right choice for the job. It has an excellent performance and allows in a relatively short time to cut a considerable number of workpieces, and with high quality. This saw also makes it possible to make longitudinal cuts in the material, but you need to know how to cut a board lengthwise evenly.
One of the most important criteria when choosing a circular saw, is the maximum depth of cut. There are devices on the market that are used for sawing materials in thicknesses from 30 to 130 mm. That is, you can choose a machine for cutting thin boards only, as well as for sawing bars.
You should also pay attention to the cutting tool itself. Blades with more teeth give a good quality cut but do not cut fast enough. Blades with a low number of teeth give a better performance but a poorer quality of cut.
Now about how to saw smoothly with a circular saw. One of the prerequisites for good workmanship is that the workpiece is securely clamped. If the material is not anchored firmly the board can “move” when sawing, and the cut will be uneven.
If the circular saw is manual, then all work should be done on a workbench, equipped with stops and guides for the workpieces. Such a device can be made by yourself, taking any table as a basis.
Before you start sawing, it is important to set the depth of cut correctly. Some handheld saws have an adjustable side guide that can be used to make a longitudinal cut. If you do not have such a device, use the same workbench.
convenient in terms of work is a desktop circular saw, which is already equipped with everything necessary. guides, clamps. It is often possible to make an angle cut of the workpiece using such equipment.
When sawing it is important not to exceed the force on the tool, otherwise the quality of the cut will be low, the increased load on the saw will lead to rapid blunting of the cutting blade.
Safety precautions should also be taken into account when using such equipment. Perform work only after checking that the saw is in good working order and that the workpiece is properly secured. Also do not neglect protective equipment. masks, goggles.
Hacksaw. simplicity and safety
Hacksaw. a simple tool that is quite suitable for the work. Speed is slow and physical effort is required, but for home use this is the best choice.
It is not difficult to correctly saw with a hacksaw. The main condition for a quality cut of the material is to make the right cut. To simplify the task, you can use an ordinary flat bar, which is used as a guide.
Often the question arises, how to evenly saw off a board with a hacksaw at an angle. To do this, a special carpentry device is used. a plane saw. over, it will not only help to make a cut at the right angle, but also allow any beginner to cut a board evenly.
It is also possible to saw a board with a hacksaw. The only problem when working with such a workpiece comes down to the fact that you will have to make a lot of effort.
The last option. the use of an angle grinder for the work with a set circle with teeth. But since a “angle grinder” is not designed for cutting wood, this method should be used only as a last resort: attempts to cut a board can have serious consequences. It is better to use a hacksaw. it is time consuming, but safe.
Pay attention to all the bends and camber of the log. a perfectly straight log is rare. So we try to turn it so as to get as little waste from it as possible, such as humpback. When the log is in place and secured, it’s a good idea to make sure it slides freely between the guide rollers.
Set the size on the ruler of the sawmill to the diameter, and to this size add the greatest height of the convexity of the log. This is the bulge that is higher than the diameter of the top or the narrowest part of the log.
With a tape measure measure measure the height of the highest part, and from this size start the size of the material, taking into account the kerf size, which is 2 to 5 mm.
What is the best way to saw?
With a circular saw
This is the most convenient tool for sawing boards. The STIHL carburetor has a better performance than some other power tools. But it is worth remembering that circular saws differ in features and applications.
Before you buy a circular saw, decide what you are going to use it for. The main sawing application is cutting or sawing of boards.
When selecting a saw you need to consider the depth of the saw. Circular saws are available with cutting depths from 30 to 130 mm. It is necessary to know with what thicknesses of boards you will saw and on this basis to give a preference to this or that saw.
It is also necessary to choose a disk for your circular saw responsibly. If you have to make a clean cut, a circular saw blade with a higher tooth frequency is the right choice. If the teeth on the disk are sparsely arranged, the work will be faster, but much rougher. It is important that when working with a circular saw, the cuts are smooth and almost without splinters. Read more about this in my book. Read more about it in the “BOOKS” section.
To start working with the circular saw set the depth of cut equal to the thickness of your board. This allows you to make the nicest possible cut on almost any surface without leaving marks.
But remember that if you make a 90 degree cut the depth of cut will be one, but for a 45 degree cut the depth of cut will be much deeper. Then check that the blade guard is clear of obstructions, otherwise it will not open.
Be aware of safety when working with the circular saw. Always wear safety glasses or, better yet, a full face mask. Remember that almost all tools are designed for right-handed people, which means that all sawdust and other debris will fly out from under the saw from the left side, so left-handers should be more concerned about the safety of the eyes and respiratory tract.
Angle grinder or angle grinder
Some craftsmen advise using an angle grinder if you have a large volume of work, low quality requirements.
Do not try this method under any circumstances. Angle grinder is designed to give a beautiful look welding seam or for cutting bricks and without a saw you just can not cope. Cutting boards with an angle grinder is dangerous.
When cutting boards with this tool, masters advise to put on it a disk with serrations for a circular saw. Imagine that while working the angle grinder caught a piece of wood in one of the nicks, you immediately release the power button (those who worked with it know that after turning off the disk will make a few more revolutions) and it is unknown where you will find your tool after that, on the floor in a couple of meters from yourself or in your body.
Or, for example, the disk got hot and burst, which is also quite possible, pieces of the hot cutting wheel scatter over the entire area, and some of them may land on you too. Other craftsmen use a disk with pobedite, which can also easily end up in your leg.
That’s why it’s better not to take the risk and to use a tool specially adapted for this work.
In order to make an even cut with a hacksaw, first you need to draw the saw trimmer line with a pencil on the board, then, set the workpiece so that you can work with it comfortably, fix it in this position. The next step, you need to set the hacksaw in a position of about 60 degrees to the workpiece, guide the saw with your thumb so that it goes exactly along the cutting line.
Start sawing as soon as your cut is deep enough that the saw can “walk” in it safely without straying from the mark, you can turn it to a comfortable position for you, usually 90 degrees, and continue sawing until you achieve the desired result. If the wood is wet and soft the teeth of the hacksaw will get stuck in it making your work more tedious and time consuming.
To make your job a little easier, oil the tool with soap and this will make it that much easier. For the novice master, the first cuts do not turn out very even, so it is better to use a bar, which will serve you as a guide.
If you need to angle your cut, use a crosscut saw. Slots are made in it in advance for the hacksaw. You will only have to attach it to the workbench, put the part into a special groove and saw at the angle you want. You’ll get a straight cut with almost no splinters.
In order to beautifully saw the boards it is better to use the help of a qualified master, if you think that you are able to cope with this work, then on no account do not make cuts angular grinder, it is better to use a hacksaw. For neat cuts along the board, the best tool is a circular or circular saw.
The important point in sawing boards is accuracy and precision, it is a painstaking and time-consuming work. The main thing is never to forget that any manual, and especially power tools can cause you harm, never disregard the rules of safety, it is better to reinsure, because the health is the most important thing.
How to work with a circular saw
The expert of category “Manual and power tools
A manual circular saw can be used at home. You have to be extremely careful when working with the tool, because you are dealing with sharp cutting and quite high speed equipment.
In this article I want to give you some important safety tips, because working with a circular saw is very dangerous.
However, the user has nothing to fear if you follow the safety standards and rules for the care and operation of circular saws.
Circular saw: the device, how it works, what kinds there are
Work on the circular machine, as well as work with a manual circular saw is to cut wood, plasterboard (not recommended), plastic, aluminum products, laminate. This tool allows you to make even, longitudinal cuts. In case the workpieces are small and a higher precision is needed, it will be more convenient to work them on a table circular saw. If you need to cut the workpieces to length or make rough cuts, your reliable helper will be a manual circular saw (circular saw).
There are several kinds of circular saws:
Most popular circular saws
How to saw with a circular saw? The question on the one hand is simple, but to understand how to do it right, first you need to familiarize yourself with the design of the equipment on which you are going to work.
The principle of operation of any circular saw is similar. A disc mounted on a shaft with two nuts always rotates sideways toward the operator. This is done to ensure that the workpiece does not bounce while cutting, the cut was straight and it was possible to hold it with the hands without getting hurt. In a manual circular saw, the principle of operation is similar. while cutting, the tool itself is pressed against the work surface.
Motors can be used as brushed, and asynchronous. Depending on the type of motor installed, the amount and timing of the job will depend on. Cheaper circular saws have collector (brush) motors.
they are good because they do not lose speed during minor voltage fluctuations, allowing the tool to work with the performance specified by the manufacturing brand. But this motor overheats during prolonged work, and if its design is not protected, it can break down.
The asynchronous motor, on the contrary, can maintain a longer operating time and is mainly used in semi-professional and professional class equipment.
The most popular table circular saws
There are three types of circular saws drive: belt drive (installed only on large machines), straight drive (one of the most common types found in any manufacturer) and straight-toothed pair (mostly used in manual circular saws).
To perform diverse work, the design provides quite a lot of interesting technical solutions. As the table circular saw has the motor under the cutting table, then at the angle of tilt and height of cut, the movement of the entire motor together with the disc is regulated by special levers. The table in this design is an inseparable part of the body. If long or wide workpieces are to be used, in most cases additional tables are provided. For straight cutting along the length or work with small workpieces, cutting at different angles there is also an additional guide, carriage and angle stops.
Since this equipment has different technical parameters, dimensions, and, of course, different purposes, you can not always get one machine and do all the necessary work on it. But if you are a pro in your business, with any type of equipment, you can achieve the desired results.
What criteria to consider when choosing a cutting method
All of the options that we will talk about below allow you to cope with the task, but each of them is suitable for certain conditions, so you need to decide in advance a few factors:
Important! Sometimes the best solution may be to buy ready-made boards, especially if the volume of work is large.
A special machine for sawing boards longitudinally. the ideal solution for those who perform longitudinal cutting constantly and in large volumes
Wood is used in many different industries. This raw material has always been popular because of its versatility, ease of extraction and processing. Wood is used to make furniture, furnishings and even entire houses.
Any master encounters with this material, but, as practice shows, to make accurate sawing board is not everyone. After the tools on the cut are often chipped or jagged, which does not add to the beauty of your product. So what’s better, to saw with their own hands or order?
Many firms offer when buying saw your boards, moreover, the price of this service is not too inflated. In the manufacture of sawn planks makes a skilled craftsman on the exact equipment that allows you to get quality blanks of the right size and shape.
Of course, you can buy expensive equipment yourself, but is it worth it if you need to saw several boards. It is only for you to choose, but if you still decided to saw boards at home, then I will tell you how and what it is more convenient to do.
Circular saw to help you!
One of the most common tools used for this task is the circular saw! Only you need to know a few basic rules. First, you need to ensure the longitudinal movement of the tree.
It is clear that to do it practically impossible on usual horizontal table, after all it will be during sawing to roll over from place to place that is very inconvenient and can cause a trauma! Which we wouldn’t want to do at all.
But what to do you ask? There is a trick that is known to all professionals under the codename “fin”.
A fin is such a device, the thickness of which corresponds to the width of the cut. But it is necessary to install this thing in such a way that it would be possible to correct, to correct its position. It’s very important!
The log is dissolved into planks by two people, it occurs according to the following technology: first it is sawn lengthwise, that is, the work is carried out by the usual method. Then, when the fin is fully in, a spacer is inserted, which should slightly exceed the width of the cut. Install a clamp-handle, which will serve two functions at once, one of which is holding, and the other will be needed to conveniently pull it.
File. spacer at this point will not allow the board to deflect somewhere, which is very convenient! Then you will need to act as follows: the first worker will pull the object by the clamp, and the other will press it to the ruler, which is used in this case to determine the width of the board!
The work, thus, in the hands of the craftsmen succeeds! Things are looking up! And the speed of the action surprises them!
You will get a lot of rafters, which can be dissolved into bars 44 cm
Before you start sawing the bars, you should always check the angle of 90 degrees. It is advisable to do this constantly, time after time, when you start work, and in general it is worth keeping the angle piece handy at all times. Also look at the small figure, so it is clearer which side you should cut the workpiece.
After drying the wood can not be perfectly flat, and usually everything changes in shape and becomes like a crescent, namely on one side two edges are bent outward (we are talking about side “A”), and on the other side will bend outward the middle (side “B”).
When you make the first cut on the circular saw it is necessary to press the workpiece with the first side to the clamp, and then the workpiece will not “float” and the back side “B” will run in a straight line on the circular saw’s disk. As a result, you get a perfectly straight line for the trimmer on the second side. If you press the workpiece together with the “B” side, then you are likely to get the same crescent moon on the first side, because the workpiece will not be pressed by the edges against the clamp, they will “float”.
