How and with what to cut chipboard smoothly and without chips

How to cut wood with a hacksaw

The saw must be driven, otherwise it will start “walking”. This needs to be realized practically. Wood is a living material, and its behavior is unpredictable. Hard annual rings, knots, cracks, high humidity and high resin levels can seriously complicate sawing.

For this reason, there is no universal tool that could take into account all the vagaries of wood, but there are many different special saws. The shape and order of alternation of their teeth are determined not by the material from which the saw blade is made, but by its purpose. Some equipment can be cut in a straight line, while others, on the contrary, are better able to cut in a circle.

When sawing, only the saw moves; the workpiece must be firmly secured. Therefore, you will need a stable support. For example, a workbench or sawhorses. The workpiece is secured with a clamp or held by hand, and especially large ones - additionally with a knee.

Sawing begins and ends by repeatedly lightly pulling the saw in the opposite direction, in other words, a “trace” is laid. At the end of sawing, you need to hold the remainder firmly so that it does not break off along with a piece of the main wood.

Sawing is one of the most common processes when processing wood. A clean, even cut is not a problem if you choose the right tool and know how to use it.

In the photo (from top to bottom): large and small hacksaws; saw with a “back”; saw with a narrow blade. Next to the left is a saw for finishing cutting.

. Why. You can use an ax too, I personally saw it in Kizhi.. ..Can you specify what kind of grooves, what kind of cuts, what accuracy is needed in mm? Maybe you’re just sawing wood, maybe you’re building a house.

Well, they bumped into the unfortunate guy. Nothing without smarts.

There are more. It will be optimal for you, as uv wrote. kluchnik, IMHO

Or you can have a chain one, even a petrol one, or an electric one.

If you cut it lengthwise, you need a hand-held circular saw. (with a cutting depth of 7 cm, we cut from 2 sides, the rest breaks)

How to saw correctly

You should always cut from the cutting side, close to the marking mowing line. This applies to both rough cuts with a hacksaw and precise cuts with a saw with small teeth. Next, it is very important that the workpiece being processed has a stable support in the form of a workbench tabletop or an ordinary desktop. For large-sized workpieces, it is better to use sawhorses. During the sawing process, the part must always be held firmly with your hand (large-sized workpieces should also be held with your knee) - in other words, only the saw should move.

Sawing begins with the first small movements at an angle of 30 to 45 degrees. Only after the saw blade has entered the wood and is fixed in it, you can start working with the saw along the entire length of the blade.

At the edge of the cut, cut only in small, sharp strokes. This will avoid breakages on the underside of the workpiece.

Cutting along wood fibers is always a “critical” situation, especially if the tree species has a large strand. The saw naturally wants to follow the path of least resistance, and if it is not restrained, it will begin to “walk.” In other words, in such cases you have to press harder on the saw than usual, which, in turn, requires a very stable position of the workpiece.

When making huge cross cuts, an ordinary hacksaw can jam. In such cases, it is better to use a rip saw with very spaced teeth. Honor only needs that the cut strip be significantly thicker than the saw blade.

to saw fresh or damp wood if the saw blade is lubricated with wax or soap.

hacksaw for longitudinal cutting of wood

The workpieces are firmly pressed against the lintel, its right edge guides the saw.

Other varieties

There are other types of wood hacksaws. Among them there is a garden hand saw, equipped with a narrow blade, for the production of which chromium steel is used. It is armed with widely spaced teeth, inclined towards the handle. It is comfortable to work with such equipment in cases where you have to focus on yourself while cutting.

There is a two-handed saw that can be used to comfortably saw huge logs or cut down trees. Two people should work with it.

A chain hand saw is a short chain with hardened teeth and two handles at the ends. It is compact and suitable for use on backpacking trips. You can work with it either by one person or by two people.

A modern and universal tool is an electric hacksaw, with which you can perform a large volume of various works. In some cases, it completely replaces a circular saw. When changing blades, they use it to saw not only wood , but also plastic and metal.

Types of timber

Several varieties of lumber are produced under a common name and within the same standard size; at the same time, they differ markedly in consumer properties. The price, of course, also varies, and the spread of its values ​​for one type of wood reaches 400%.

Natural humidity

It is a product of sawing tree trunks without any surface treatment. Humidity – 18-22%. When dried, it shrinks by volume up to 15%; During the drying process, deformations and cracks may appear.

Uneven drying led to cracks in the wall.

Dry

Chamber-dried timber has a moisture content ranging from 0 to 12%, which minimizes shrinkage and the likelihood of deformation or cracks during operation.

Let us clarify: in practice, material with a moisture content of 8-12% is sold under the name “chamber-drying timber”. Absolutely dry wood is used primarily in the manufacture of furniture and requires immediate conservation immediately after it leaves the drying chamber.

Profiled

Longitudinal milling of the upper and lower surfaces of this building material makes it ideal for the construction of walls: the seams are not only not blown by the wind, but also eliminate the lateral displacement of the crowns. Profiled timber is produced both dry and with natural moisture.

typesetting

Laminated or laminated timber differs from other types in production technology, being a laminated laminated structure made of relatively thin boards (lamellas).

Log house made of profiled laminated timber.

What does such a structure provide?

Main settings

The effectiveness of using a hacksaw for wood largely depends on its technical characteristics. The main ones are:

• the material from which the saw blade is made;
• length of the canvas and its shape;
• tooth size and shape;
• type of handle.

READ Replacing a Black and Decker Circular Saw Blade

When choosing a tool, you need to pay attention to each element of the characteristics. Only in this case you won’t have to regret the purchase.

Handle type

The type of handle and the material from which it is made largely determine the ease of working with a hacksaw on wood. It is best to work with a saw equipped with a solid plastic handle with rubberized finger inserts. The handle, made of two parts, is less comfortable, as it does not have sufficient rigidity.

There are also hacksaws with reversible handles. They are usually equipped with universal and bow saws, in which blades can be changed during operation.

Tsulaga

When processing small workpieces, the tsulaga shown in the pictures below can be of great help.

To make it, you will need a piece of wood slab approximately 20 x 30 cm in size and 2 mm thick, as well as two planed strips, which must be fixed to the slab as shown in the figure. To prevent the slab from bending and breaking, the planks must be positioned transverse to the direction of its core layer.

How to work with a circular saw

The lower bar of the tsulaga rests against the edge of the tabletop and thus sets the correct direction for the cut; the shortened upper bar ensures good centering of the saw.

If you have to saw long boards or planks, then a second tsulaga will not hurt, which will serve as a stop for the other end of the workpiece.

A piece of wood slab and two pieces of plank are enough to make a practical tsulagi.

Before starting sawing, the saw placed at an angle must be pulled towards you several times.

Adhesive tapes

To protect the back side of the plywood, tape is applied along the cutting line. This method helps prevent large pieces from breaking off, which is especially effective if you decide to use a manual or electric jigsaw. However, not every adhesive tape is suitable for these purposes. For example, masking tape in this case will be completely useless due to its small safety margin.

Before you start sawing , tape with fiberglass or aluminum reinforcement is glued to the surface. The requirements for its width are as follows: there should be a margin of 1.5-2.0 cm on both sides of the cutting line. It is better to paste by pressing the tape with a dry cloth, preventing the formation of wrinkles and gluing.

After the saw blade or electric jigsaw has stopped working, you should remove the tool, first unplugging it from the power supply. Then start peeling off the tape. In this case, great care should be taken so that sudden movements do not cause the tearing of small fragments of the laminated surface that inevitably form during cutting. Therefore, it is necessary to abandon the use of materials with a strong adhesive base. When choosing such a tape, you should take into account its adhesive ability and ease of cleaning from rough surfaces.

Sharpening a hacksaw

• vice;
• hammer;
• calipers;
• pliers;
• emery block;
• sandpaper.

You should also have the following types of files in your arsenal:

• flat and diamond-shaped with a medium-sized notch;
• triangular file;
• triangular with velvet notch;
• needle files with notches of different calibers.

For sharpening, a special device is used that allows you to fix the blade at angles of 45 and 90 degrees. If you need to sharpen a cross saw, proceed as follows:

• the canvas is fixed at an angle of 45 degrees;
• sharpening is carried out with a triangular file with an apex angle of 60 degrees;
• the file is directed onto the hacksaw tooth at an angle of 60 to 75 degrees;
• first, with several movements of the file away from you, the left edges of the odd teeth are processed;
• After this, the hacksaw is turned over and the left edges of the even teeth are processed.

When sharpening a longitudinal hacksaw, proceed as follows:

• the canvas is fixed vertically;
• for sharpening, a rhombic file with a fine notch is used (needles can be used);
• during sharpening, the file is directed strictly parallel to the table;
• otherwise the process is similar to the previous one.

Burrs that appear on the edges of the teeth must be removed using an emery block or a file with a velvet cut.

The process of sharpening a saw for the first time is quite difficult, so it is better to carry it out in complete silence and with maximum concentration. It’s worth doing this a few times, and then things will become habitual and go “like clockwork.”

A saw is often used to process wooden blanks and change length and shape. This tool is represented by a combination of a working part and a handle. In this case, the working part is represented by a metal plate with cutting elements, which are located in a certain sequence relative to each other. Only with proper and timely maintenance can the possibility of product wear be eliminated. An example is the setting of the teeth, which is performed from time to time to ensure smooth movement of the tool along the resulting cut.

How to cut plywood without chipping with a circular saw?

It is recommended to cut on a flat floor. The plywood sheet is laid on wooden blocks of equal thickness, placed perpendicular to the cutting line. Full support from below ensures that no corner of the sheet breaks off at the end of the cut. A metal or wooden guide is installed on top, which is fixedly fixed with clamps.

In order to cut laminated plywood accurately and without chipping, you need:

• Setting the minimum cutting depth. On the opposite side of the sheet, the teeth should protrude 2–3 mm. With this setting of the cutting depth, the blade does not chop, but carefully cuts the wood.
• Choosing the right circular saw. For gentle cutting, a blade with a minimum size and a large number of teeth is selected (for example, No. 140).
• Low feed speed of the cutting blade when moving without stopping. In this case, the teeth do not cut, but gently cut the wood without chipping. To properly cut laminated plywood, it is also recommended to adjust the blade speed to maximum. Disadvantage of the method: the carpenter runs the risk of overheating the canvas.
• Laying adhesive tape in place of the cut. To do this, it is recommended to use masking tape that does not leave marks on the surface of the sheet. Upon completion of the work, the tape is removed at an angle of 90°, moving towards the cut.

If you have to process laminated plywood, it is recommended to also tape the sole of the circular saw. This avoids scratches on the front surface of the sheet.

Both an electric jigsaw and a circular saw are suitable for cutting such material. The first option is indispensable in the case of a figured cutting path.

To cut thick plywood without chipping with an electric jigsaw, it is recommended to use any of two types of blades:

• finishing series CleanWood (Bosch);
• on metal.

A regular circular saw is also suitable for even cutting of a sheet of plywood. It is enough to install a blade with a fine tooth (for example, No. 140), adjust the cutting depth within 12–13 mm and lay the sheet on even wooden blocks. It is recommended to make the cut along the guide, with a low tool feed speed and without interruptions.

If the front surface of the sheet is laminated, then the cut area is preliminarily covered with masking tape.

For anyone who doubts which saw is best to cut plywood, we recommend contacting a specialized company with laser cutting and professional cutting equipment.

When producing various finishing works or making furniture, the use of plywood is a common practice. At the same time, home craftsmen are faced with a choice: how to cut plywood and how to achieve a perfect cut without chips. When cutting such material, some difficulties arise: the sheet is large in size, and the structure of its base creates difficulties when sawing. Knowing some features, you can achieve excellent results when working with an electric jigsaw, hand saw or circular saw. The main condition is to ensure reliable fixation of the plywood.

READ What parts does a hacksaw consist of?

Plywood is a material that is practical to use and easy to process.

Hand electric saw

• Saber. It is an alternative to a jigsaw, but is more suitable for quickly cutting off excess without forming an even and precise edge.
• Disk. It is used most often because it allows for large-scale work. The disadvantage of the device is that cutting is only possible in a straight line.

A reciprocating saw is not designed for precise cutting, so it can only be used for rough cutting of plywood, while a manual circular saw is considered one of the best options for such work

It is better to cut plywood to specified sizes using the latter option, taking into account some application features:

• The ability to adjust the insertion depth minimizes edge damage.
• Small discs made of carbide material with frequently spaced teeth are suitable for the job.
• Ease of use. The tool weighs little and does not require a special installation site.

When choosing a suitable disk, you need to pay attention to the tooth alignment: a slight discrepancy is convenient for thin material, a larger discrepancy is suitable for thick slabs.

What is the difficulty of using an angle grinder with wood?

The first thing that experts pay attention to is that the blade rotation speed of an angle grinder is much higher than that of a circular saw. Therefore, if you will be cutting not only metal and concrete, but also working with wood, buy an angle grinder with a disc rotation speed controller and soft start.

To cut a log, saw a tree with a grinder or fell a trunk, you need to work at medium speeds - at a high speed of rotation of the nozzle, any obstacle in the path of the cutting edge (wire, nails, resin, clamping the disk, incorrect angle of the disk, multidirectional wood fibers) can provoke a powerful a jerk of the tool, and you may simply not be able to hold the grinder in your hands. In addition, you can cut down a tree on your site using a grinder only by holding it horizontally, and this is a high risk of injury.

Before starting work, determine which side it will be more convenient for you to screw in the handle-holder of the grinder, and at what angle you should turn the protective casing in order to maximally protect your eyes and face from sawdust.

Pre-route the power cable along a safe route and not in the path of a falling tree.

Important! Under no circumstances should you cut a tree trunk or a lying log with a grinder without adjusting the rotation speed of the blade. Also, do not use metal discs, grinding or polishing attachments for this purpose. It is best to use a wood disc with large teeth.

How to cut plywood at home

Determining the optimal device for cutting wood panels is not the most difficult task; standard equipment can be used for the process.

Jigsaw

This device is the optimal solution when it is necessary to cut plywood into parts. When choosing such a tool, you need to consider some nuances:

• It is recommended to abandon cheap models, since they do not achieve the desired result and significantly slow down the cutting process.
• A power switch is required. This allows you to adjust the jigsaw to slabs of different densities.
• The ability to adjust the stop plate ensures leveling for an accurate and straight cut. If the device does not have this function, then the sole should not be curved.

The main factor determining the quality of the cut with a jigsaw is considered to be the pitch and size of the tooth, and only then come the local settings of the tool itself, such as turning off the pendulum stroke and adjusting the frequency

The correct choice of file is carried out taking into account the following conditions:

• Preference is given to branded blades designed specifically for sawing plywood. They provide the highest quality results.
• The nozzle may have different tooth directions. Depending on the position of the cutting part, one of the sides of the slab will be completely free of chips.
• An alternative option allows you to use a metal blade. But this solution has disadvantages: the work is carried out very slowly, and small teeth become clogged.

It is with the help of an electric jigsaw that you can quickly and efficiently cut plywood at home. The tool makes it easy to do the process yourself.

Attention! The device is suitable for complex shaped cuts. Difficulties arise when processing thick sheets: the nozzle is quite thin, so it collapses, which requires additional preparation of the fragment.

How to cut plywood with a hacksaw

Installation of laminated veneer sheets involves varying degrees of processing. The greatest difficulties arise when cutting is necessary; cutting plywood is more labor-intensive due to the layering of the material. To achieve a high-quality result, you need to choose the right device, which will allow you to avoid problems and obtain parts without chips.

Hand saw

When cutting plywood with a hand saw, physical effort is required due to the significant density of the material. This tool is used when it is necessary to cut a sheet of plywood into identical fragments.

A hand jigsaw is considered the best tool and allows you to decide in advance how to cut plywood without chipping, eliminating the need to purchase electric tools. It can be used to produce a small number of elements of complex shapes. Having certain skills in working with a jigsaw, you can make a neat cut, however, due to high labor costs and low productivity, this method cannot be called optimal.

If you don’t have electric tools or a simple jigsaw at hand, you should resort to using a simple hand saw. To make cutting a sheet convenient and to avoid chipping, the tool blade must have a large number of small and well-sharpened teeth. The angle of the saw to the plywood sheet should be sharp. It is recommended to avoid jerking and make even movements with strong pressure.

Tip: The cut of a regular saw is rough, so it is recommended to sand the end parts after finishing the sawing.

How to make an even beam from crooked rafters using a circular saw: Review + Video

How to make an even beam from crooked rafters using a circular saw. In fact, many were probably surprised by the title of the article, since you can get the base on a jointer or using a milling cutter, but it’s not for nothing that they say that laziness is the greatest engine of progress.

We suggest you try making the base directly on a circular saw, especially since the length of the beam will be approximately 0.3 meters. It’s also worth checking out the photos of the source material and the final result.

So, how to make an even beam? To begin with, we suggest cutting the rafters into pieces of the required length.

The advantage of sawing logs with a chainsaw

Cutting into boards can be done using tools such as an electric chainsaw and additional accessories designed to simplify the work. When choosing certain products, you need to focus on the amount of work expected. Stationary sawmills are expensive and are purchased only if you plan to organize a business to create boards.

The most accessible tool for the job is a chainsaw. Such devices have several advantages over electric ones:

• the chainsaw can be used anywhere, regardless of the availability of an electrical outlet;
• the tool is suitable for working in conditions of high humidity;
• professional chainsaws are significantly more powerful than electric ones;
• You can use the chainsaw continuously for an hour.

To cut logs into boards, a special frame is used together with a chainsaw, which is attached to the device and allows you to create boards of the same thickness. A device is also needed to secure the log in one position. In addition, you will also need a guide.

READ Miter saw Practyl 1400w 210x30 mm

Since household gasoline saws are not designed for heavy loads, it is worth using professional tools for sawing logs. When choosing, you should pay attention to devices with a power of more than 7 horsepower. Before work, the fixed frame is adjusted in accordance with the selected width of the boards. To create a frame, you can use legs from a school desk or metal corners.

Chainsaw device classes

Currently, all chainsaws on the Russian market can be divided into three main classes:

• Conventional household devices that are designed for simple work. These chainsaws do not have much power, and do their job perfectly. With the help of these chainsaws, you can easily prepare firewood for a bathhouse or cut down an unnecessary tree. And the capabilities of such saws are easily compensated by their low weight and convenient control.
• Semi-professional chainsaws designed for any work, from repair and construction activities to felling of timber.

  
  But such saws have one drawback. They cannot be used for eight hours a day. Because of this, they are called semi-professional. These devices are usually used by lumberjacks to trim knots.

• Professional chainsaws specialize in wood cutting. Their operating time ranges from 10 to 16 hours a day and these saws can be used for seven hours without stopping.

Hacksaw - simplicity and safety

A hacksaw is a simple tool that is quite suitable for the job. And although the cutting speed is low and considerable physical effort is required, such a saw is the most acceptable option for home use.

to cut wood correctly The main condition for a high-quality cut of the material is to make the cut correctly. To simplify the task, you can use a regular flat block, which is used as a guide.

The question often arises of how smoothly with a hacksaw at an angle. For this purpose, a special carpentry device is used - a miter box. Moreover, it will help not only to make a cut at the desired angle, but will also allow any beginner smoothly .

You can also saw off the timber with a hacksaw. The only problem when working with such a workpiece is that you have to put in a lot of effort.

The last option is to use an angle grinder with a wheel with teeth installed for the work. But since the “grinder” is not intended for cutting wood, this method can only be used as a last resort: attempts to cut a board can result in serious consequences. It’s better to use a hacksaw - it’s labor-intensive, but safe.

Sharpening a hacksaw

Like any other tool, a hacksaw will work well if it is sharp.
With frequent use, the question of sharpening a hacksaw for wood very soon arises. A hand saw for wood becomes less sharp over time; the teeth wear down, becoming rounder on the sides and in front of the edge. Therefore, it becomes more difficult to operate the saw. To restore the previous sharpness of the teeth, it is worth sharpening them. Please note that before and after sharpening, the teeth must have their original height and angle pitch.

It is also worth considering the fact that not every hacksaw can be sharpened. For example, a tool that has small teeth should not be sharpened. In addition, hardened steel teeth cannot be sharpened. A large wood hacksaw lends itself best to sharpening.

Before you start sharpening, you should separate the teeth. To ensure free movement along the workpiece, as well as to avoid pinching the tool, the teeth must be moved apart smoothly as they deepen.

The alignment of the teeth must be bent in different directions to a specific distance. After this, the width of the cut will increase and will have a larger width compared to the thickness of the teeth. There are gaps on the sides. Upon completion of the layout, the hacksaw will easily move back and forth, and the blade will not touch the surface of the cut, as a result of which the master will freely remove the wood with each layer.

When setting, it is worth considering the fact that as the width of the teeth increases, the cut will widen. Therefore, you will avoid the hacksaw getting jammed. However, this does not mean at all that if the teeth are set excessively (increasing the width), a wide cut will be obtained; on the contrary, the teeth will tear the wood and the work will become harder. The optimal width of the teeth is one and a half to two times greater than the thickness of the hacksaw blade. For this reason, to cut raw wood, the teeth should be set aside by 0.5 - 1 mm, and dry wood - less than 0.5 mm.

A special tool called a setting tool will help you bend the teeth. This is a small metal or wooden plate with a small slot, the width of which is greater than the thickness of the hacksaw. Often the wiring is equipped with an adjusting screw, with which you can achieve an even bending pitch of the teeth.

Wiring procedure:

• clamp the saw in a vise so that only one teeth peeks out
• fix the vice on a convenient flat surface, for example, on a table
• bend the teeth using an adjustable device in the opposite direction
• do not bend the teeth completely, otherwise they will break
• at the end of the setting, you need to check that the teeth are at the same distance and do not look out.

Sharpening a tool can be called a real art, for this reason it is worth following certain rules:

• securely fix the hacksaw. The blade must be secured in a vice or other wooden device that is installed in a well-lit place and on a stable surface. High-quality sharpening will not work on your knees, chair or brick.
• use high quality tools. Don't save money by buying cheap tools. You should definitely buy a quality file
• For long service life of a hacksaw, it must be cleaned with a wire brush and rubbed with charcoal. This is necessary so that the hacksaw does not clog or become dull.
• The handle of the hacksaw should be held in the right hand, and the end should be supported with the left, pointing the file at the teeth. It is necessary to press the teeth smoothly, pointing the file in one direction. When returning the file, try not to touch the teeth.
• you need to try to remove the metal from the edge of the teeth evenly. For convenience, you can count the number of movements; for each tooth it should be the same
• A file that has a velvet notch will help you get rid of burrs from your teeth. The notches on the side edges of the hacksaw must be removed using a whetstone.

At the end of sharpening, you should definitely check the quality of sharpening and the sharpness of the teeth. A well-sharpened edge does not shine.

How to cut a board lengthwise

For carpenters, boards and beams are the most common blanks, from which crafts and wood products are subsequently produced. And the first thing the material undergoes is sawing into pieces of the required length. At the same time, you should know how to evenly , because performing this operation incorrectly can ruin the workpiece or significantly affect the appearance, and not for the better.

At large enterprises, the problem of how to saw off a beam or board evenly Any serious production facility has high-precision equipment that performs this type of work. At home you have to make do with what you have on hand. At the same time, you still need to be able to use the tool or equipment correctly in order to saw off the board correctly, and the cut turns out without flaws.

Note that many enterprises that sell boards and timber provide cutting services. And for this they use the same specialized equipment, so the purchased material will be cut with high quality. But it is not always possible to use such a service, and it often happens that only one piece needs to be cut.

Let's consider two methods that suit us: cutting logs lengthwise and crosswise

• Cross cutting is used to produce parts in the form of disks or cylinders.

• And the longitudinal method is used to dissolve logs into boards , beams, and slats. For this purpose, many devices are used in production. We will look at how you can cut a log at home, on your own.

For cutting you can use:

• Circular
• Pilou
• Grinder with attachments

So, we have already removed the bark from the log, so we move on to the next steps:

• We fix the log on the guides or bed
• We saw off the slab on one side to get a smooth surface.
• Turn the log over onto the bed with its flat side and remove the second slab
• Next we cut the log into planks

Circular saw – high performance and ease of use

A circular saw is the best option for performing the work. It has excellent productivity and allows you to cut a considerable number of workpieces in a relatively short time, and with high quality. In addition, such a saw allows you to make a longitudinal cut of the material, but you need to know how to cut the board straight along .

One of the most important criteria when choosing a circular saw is the maximum depth of cut. There are devices on the market that cut materials with a thickness of 30 to 130 mm. That is, you can choose a machine both for cutting only thin boards and for sawing bars.

Recipe. how to cut straight with a simple hacksaw

It is also worth paying attention to the cutting tool itself. Discs with a large number of teeth will provide a neat, high-quality cut, while the cutting speed will be low.

Calculation of logs for sawing into beams.

So, let’s get started, first we need to decide what size the beam will be, as well as the dimensions of the material (boards) that we want to get to the beam.

Let's start by taking the required timber, for example, 150 x 150 mm, unedged board 25 mm, 30 mm, 40 mm.

For those who do not know what a non-edged board means, we explain that this is a board of various widths that does not have specific boundaries due to the presence of bark along the edges, but has a certain thickness size.

Next, take a 25 mm, 50 mm edged board. We think it’s clear here that an edged board is a board that has a certain size, both in width and thickness, and has no bark, or, as they usually say, no wane.

Timber calculation

Let's start the calculation by measuring the diameter of the log, and for us it is, for example, 30 cm. Or, for ease of calculation, we will convert it into millimeters, it will be 300 mm. Since our timber should be 150 mm, we take 300 mm and subtract 150 mm, leaving the remainder with 150 mm, which will be used for boards.

300 — 150 = 150

From the upper and lower edges of the diameter of the log we subtract 5 mm per slab, that is, we will divide the 150 mm remaining on the boards, we get 150 minus 5 and minus 5, and the remainder we get 140 mm.

Cutting boards at home

You can cut a board at home using the following tools and equipment:

• a circular saw;
• hand saw ;
• angle grinder (“grinder”).

Each of these options has its own specifics, which are important to consider before starting work, that is, you need to know how to cut a beam or board with one or another tool so that the quality of the cut is acceptable.

Lightweight nozzle

Such devices are often used, but they should only be used when creating boards for fences or sheds. This is due to the fact that the attachment is secured to the tire only on one side.

Attachment for longitudinal sawing

When using this attachment, sawing occurs in a horizontal direction. It is fixed to the rail using special clamps and allows you to create boards of equal thickness. After the work is completed, the boards are dried and can then be used in construction.

Long sawing technique

The most difficult stage of the process is making the first cut. To do this you need:
