How to cut a bar along a chainsaw


Types of cutting logs

Sawing logs into boards is carried out in two main ways:

In addition, additional methods are possible:

  • mixed
  • semi-radial (rustic)
  • central.

Radial sawing is a type of sawing during which the axis of the cut runs through the core of the log and, as a result, the annual rings in the section of the board form an angle of 76. 900. The lumber obtained with such a cut has a uniform color and texture. Timber is almost not subject to deformation during shrinkage and does not swell when moistened, because the dimensions of the wood change mainly along the line of the rings (across the fibers). In radial sawn timber, the annual rings are located in thickness. Such materials are distinguished by the highest performance indicators in comparison with other types of sawn timber.

Tangential cutting is carried out tangentially to the lines of the annual rings at a short distance from its core. The layers of the resulting boards are distinguished by a pronounced texture and a bright wavy pattern of annual rings. Such lumber is characterized by higher shrinkage and moisture swelling coefficients compared to radial sawn boards. As a result, they are strongly deformed when exposed to moisture. Such boards are in demand for use in dry conditions.


Rustic (semi-radial) and mixed types of sawing have signs of two main types of sawing at the same time: radial and tangential. Therefore, they exhibit average shrinkage and swelling rates. Rustic cut boards are distinguished by straight lines of annual rings, which are located at angles of 46. 75 degrees. to the layers. Mixed sawn timber differs in that the lines change from straight at the edges (in width) of the board, to arched towards the middle.

The center cut is made directly in the center of the trunk and contains the core. Taking into account the fact that the core of the trunk is wood with the lowest strength values, center-cut sawn timber is characterized by a structure that is not uniform in strength.

How to cut a log lengthwise. disappointing realities

All of these recommendations are good for ideal logs, but as you know, the ideal is rare. Basically, almost all logs have various shortcomings, and you have to adjust and invent ways of cutting in order to avoid wood loss and get as much quality material as possible.

As in the previous case, before you cut the log lengthwise, you need to remove the slab from it. For those who do not know, a slab is a board that has one sawn surface, and the other either gets partially processed or does not touch at all.

After removing the slab, the next step is to make an unedged board, as already mentioned above. Ripping a log produces boards, but with rough edges. In the process, because the log is not ideal, it is necessary to turn it over periodically and identify the best options for further use. Sometimes, for cutting one log, it has to be turned over 180 degrees several times in order to minimize defective boards.

If there is a possibility of obtaining good quality material from the other side of the log, you need to continue the process from it and so on until the wood is fully used.
Very often, after sawing, a bar remains, it can also be put on slats, boards or used in its original form.

Sawing logs into planks with a chainsaw

Benefits of sawing logs with a chainsaw

The saw and ax, as woodworking tools, have long faded into the background, giving way to more efficient gasoline and electric saws. The chain saw operates with a two-stroke gasoline engine; a sharpened chain is a working tool. Main advantages:

  • high productivity, which greatly facilitates human labor;
  • mobility, it is easy to transfer it from place to place, to load it into a car, it is not tied to an energy source;
  • can be used in conditions of high humidity and even in rain;
  • the possibility of using various types of attachments to perform different tasks;
  • ease of use;
  • financial affordability in comparison with specialized woodworking machines.

Therefore, not only experienced professionals prefer this tool, but also the owners of farms successfully use the chainsaw for solving everyday tasks in the garden and at the construction site. When building ancillary structures, it may be necessary to saw the log. It is very easy to cut the workpiece into boards in a workshop, but it can be done at home.

The order of the main work

  • Now you need to start the chainsaw and make the first cut.
  • Next, you need to free the log from stops and boards and attach a leading ruler on the cut surface of the log in the direction of the next cut. The ruler is attached directly to the surface or to the ends of the log using supports. The second cut is made perpendicular to the first cut.
  • The log must be turned and secured with a board point-blank to the ground.
  • You do not need a leader ruler for further actions. One of the cut sides serves as a guide.
  • It is necessary to adjust the thickness of the cut on the frame and saw off the log from the other side in such a way that you get a bar with bark left on only one side.
  • This bar must be turned over and fixed in such a way that the fixing point of the fixing board is as low as possible.
  • Then you need to adjust the frame to the required thickness of the board and cut the timber into boards.

Circular to help you!

One of the most used tools that are used to solve this problem is a circular! You just need to know a few basic rules. First, it is necessary to ensure the longitudinal movement of the tree.

It is clear that it is almost impossible to do this on an ordinary horizontal table, because it will roll from place to place during sawing, which is very inconvenient and can threaten injury! What we absolutely would not like.

But what do you ask? There is one trick that is known to all professionals under the code name “fin”.

A fin is a device whose thickness corresponds to the width of the cut. But you need to install this thing in such a way that it is possible to correct, correct its position. It is very important!

The log is dismissed into planks together, this happens according to the following technology: first, they cut it lengthwise, that is, the work is carried out according to the usual method. Then, when the fin fully enters, a spacer is inserted, which should slightly exceed the width of the cut. We install a clamp-handle, which will perform two functions at once, one of which is holding, and the other will be needed in order to conveniently pull it.

File. the spacer at this moment will not allow the board to deviate somewhere, which is very convenient! Next, you will need to proceed as follows: the first worker will pull the object by the clamp, and the other will press it against the ruler, which is used in this case to determine the width of the board!

Thus, the work in the hands of the masters argues! Things are going uphill! And the speed of action surprises them.!

How to cut a log yourself along with a chainsaw

Planks and beams are one of the main building materials. But not everyone has the financial ability to buy ready-made boards. In such situations, one of the solutions is to independently engage in timber harvesting on a plot taken in the forestry.

Sawing logs along

To get a smooth cut, you need to install a guide. It can be a mini-sawmill of an industrial standard. But such devices are not cheap and not everyone has a. Therefore, logs are usually fixed with self-made holders from boards with the same guide.

Sawing logs into planks is carried out with a chain for ripping. If this is not the case, an ordinary chain is suitable, which is sharpened at an angle of 10 degrees. Exclusively in the process of work, you will have to undermine it at times. A nozzle is installed on the chainsaw. a guide frame for an even cut.

Nozzles for sawing logs

The chainsaw is a good all-round tool in the home garden. First, it should be borne in mind that it has great power, compactness. Thanks to the centrifugal clutch, all systems and units of the mini-engine operate without overloads for a long time; power makes it possible to install any attachments. The chainsaw can be operated in any position and in any area, because it is autonomous, has a diaphragm carburetor.

How to adapt the mechanism for cutting logs into boards? To do this, it is enough to install the proper attachments on the chainsaw.

To cut a log along its entire length, a nozzle for longitudinal sawing of logs in a horizontal plane is suitable. Thanks to her, the boards are of the same thickness. After proper drying, they are suitable for construction. The nozzle is a small frame that is attached to the tire from 2 sides.

In addition, there is a lightweight nozzle, which is fixed only on one side. As a result, the boards are not as flat as in the first case. Fences, sheds are built from such boards.

The auxiliary equipment is a drum debarker-stainer.

With its help, logs are simply cleared of bark.

The nozzle is a drum, it works thanks to the V-belt transmission. It is attached to the moving belts using special pulleys on both sides of the axis. The method of selection of the pulley diameter can be used to select the best shaft rotation speed.

To cut a log lengthwise, you must perform the following steps:

  • Make a leading ruler. To do this, you need to fasten two straight long boards at an angle of 90 degrees.
  • Place the log on the stops, thus fixing its position.
  • Attach nozzle.
  • Using self-tapping screws, attach the supports to the ends of the log on both sides. Check horizontality with level.
  • Attach the leading ruler to the supports with self-tapping screws.
  • Install another support board horizontally. which should rest on the ground and slightly raise the log.
  • Using a chainsaw with a horizontal cutting attachment, saw off the first piece of log.
  • Move the guide fence, fix it.
  • Make the second cut of the log perpendicular to the first.
  • Further, the leading ruler can be omitted. The resulting board will serve as a guide.
  • Determine the thickness of the cut by the frame.
  • Make the next cut perpendicular to the second. As a result, a piece of wood should remain, the underside of which is covered with bark.
  • Make a fourth cut to separate the rest of the wood, which is with bark. You will get an almost perfectly flat block of wood.
  • Then cut the bar to the middle.
  • Turn it over to the opposite side and continue cutting to the end.

If the thickness of the boards does not matter, it is not necessary to cut off the barked edges. In this case, you can use a staining agent and cut into boards from the very beginning.


Cross-cut is used to cut logs for firewood, as well as to create transverse wooden discs for building garden benches, decorating garden paths, etc.

Sawing a log across is done as follows:

  • Place the log horizontally on wooden supports 0.5 m high.
  • If necessary, you can clean it from the bark.
  • Using an ax or a saw, make cuts-marks at equal distances from each other.
  • Cut the log according to the marks.

No special attachments and chains are needed for this job. A regular chain will do.

The advantage of a chainsaw as a sawing tool

You can cut a log using a sawmill, a petrol or electric saw and additional devices. When choosing one of these tools, you should consider the amount of work to be done. The cost of the cheapest stationary sawmill, together with all the accessories, is 150 thousand rubles. The chainsaw is much cheaper. It is more convenient than an electric saw for the following reasons:

  • Electricity is not required to operate the tool. this makes it possible to use the chainsaw on plots.
  • powerful than an electric saw.
  • Starts smoothly and allows convenient speed adjustments, reducing the chance of chain breakage.
  • The overrun brake responds faster than a saw.
  • Long working time without interruption. up to one hour.
  • Can be used in high humidity conditions.

Features of sawing with a homemade tool

Sawing a log into boards can be easily done using a self-made tool. It is not difficult to make it. To do this, follow these steps:

  • As a support, you need to use a frame from a school desk or a pipe with a cross-section in the form of a square, its optimal size is 20×20, and more is allowed.
  • It is necessary to build two clamps, at one end mount a cross member with two holes for tie bolts, make a ledge for the bus in the middle.
  • For longitudinal sawing of logs into boards, you need to make a support frame, its width should be less than the length by seven to eight centimeters.
  • Then, two parts ten centimeters long are welded to both sides, holes are made for bolts, a handle is attached in the middle for ease of use.
  • Then you need to insert the clamps into the grooves, install the bus, fix everything carefully.

It is not difficult to work with a homemade tool, for this you will need goats, they will serve as a support. In addition, you need to prepare a metal strip or board to use as a guide. A log is laid from below, the required height for work is set.

How to cut a log yourself along with a chainsaw

Planks and beams are one of the main building materials. But not everyone has the financial ability to buy ready-made boards. In such situations, one of the solutions is to independently engage in timber harvesting on a plot taken in the forestry.

Types of working attachments

When sawing logs with a chainsaw, various attachments are used.

  • Rip saw attachment. It is used for sawing a log lengthwise, the process takes place in a horizontal position. After work, the master gets the same thickness for the product. The finished materials undergo a drying process, after which the boards are used in construction. In appearance, the device is a small frame, it is attached to the tire on each side.
  • Drum debarker (gummer). With the help of such a nozzle, it is easy to dissolve the log, it works due to the V-belt transmission. Attaches to belts on both sides using special pulleys. The rotation speed of the shaft depends on the size of the pulleys, so the performance of the nozzle is easy to change. This technology forces the master to carefully monitor each stage of the process; some specialists use an assistant during this cut. But this option requires increased security measures.
  • Sawing with a lightweight nozzle. The method is not very efficient, but it is used quite often. The element is fastened on one side, but the workpieces are slightly uneven. Such materials are necessary for the construction of barns or fences.

The procedure for performing preparatory work

To cut a log lengthwise, you need to perform the following sequence of actions:

  • Take two straight boards and attach one to the other at right angles. The result is a solid flagship line.
  • To support the made ruler, you need to make stops from the boards.
  • Barrels must be moved using a turner.
  • The log should be placed on a comfortable base.
  • On the tire of the chainsaw using nuts, you need to fix the frame.
  • Lead ruler supports must be attached to the ends of the log, checking the horizontal position with a level.
  • Self-tapping screws must be used to fix all brackets and structural elements. Nails are not suitable for these purposes, since they are difficult to remove in the future without causing damage to structural parts.
  • The guide ruler must be attached to the supports with staples and its height must be adjusted taking into account that the cut will not go along it, but approximately one centimeter higher.
  • The log must be rotated and the second plank must be fixed in such a way that it rests on the ground and supports the log.
