Slinging logs on the boards of a chainsaw: what will be needed for this

Some people have the opportunity to take a certain area for logging in the forest to dissolve the trunks, but as a chainsaw to dissolve the log onto the boards, if you never had to face it? Those who have been engaged in logging for a long time can do this without any devices. It is enough for them to beat off on the trunk a longitudinal fishing line for a trimmer and with its help cut a beam or board.

But if you have never done this, then you will need certain devices that we will talk about now, and also show the thematic video in this article.

Cut the logs onto the boards of a chainsaw on the forested

Tool and equipment for sawing logs

Depending on the total number of logs, their lengths, thicknesses and the estimated quality of the future lumber, different tools and specialized equipment are used for sawing. To obtain a small number of lumber at home, the manual method of processing of trunks using chainsaws and ordinary hand-cutting with teeth for longitudinal sawing is quite acceptable.

Pylorama is a fairly common type of sawmill equipment. It is a woodworking machine with frame saws, designed for a longitudinal cut of logs to obtain a trim and a beam. On sawmills it is possible to process logs with a diameter of 15 to 80 cm and up to 7 m long.

Logs to Lumber

Slinging the trunks of trees on round.Fed (circular) machines is carried out by means of a disk saw. Such machines can be droofive (single.Disc) and multi.Digger (multi.Disc). Single.Disk round.Up machines operate, as a rule, with small and low.Quality source material. Multi.Disc machines are designed for cutting a large diameter round.

circular, process

The most popular are the so.Called ribbon sawmills, both vertical and horizontal. As a cutting tool, they use a tape canvas, worn on pulleys. Ribbon machines provide high.Quality longitudinal and mixed sawing of logs on a board and a beam with a minimum amount of waste.

Wood cutting lines are used in large enterprises in the production of lumber on an industrial scale. They provide high surface quality and accurate geometry of the final product and have the greatest performance.

In addition to the above, with the mass production of lumber, other types of highly specialized sawmill equipment are used: hammer, edge-cutting, tape-dentive and other machines.

How to work with a hand.Free saw

The saw needs to be kept, otherwise it will begin to “walk”. This must be understood literally. Wood. Living material, and its behavior is unpredictable. Hard annual rings, knots, cracks, increased humidity and high resins can seriously complicate sawing.

For this reason, there is no universal tool that could take into account all the whims of wood, but there are many different special saws. The form and order of alternation of their teeth is determined not by the material from which the saw canvas is made, but by its purpose. Some kind of tool can only be sawed in a straight line, the other, on the contrary, is better in a circle.

When sawing, only the saw moves, the workpiece should be securely fixed. Therefore, you will need a stable support. For example, a workbench or goats. The workpiece is fixed with a clamp or adhered by the hand, and especially large. In addition to the knee.

The sawing begins and ends with repeated light stretching of the saw in the opposite direction, that is, the “trace” is laid. At the end of the sawing, it is necessary to hold the rest tightly so that it does not break off with a piece of the main wood.

Sawing is one of the most common processes in the processing of wood. Pure, even cut. Not a problem if you choose the right tool and be able to use it.

In the photo (from top to bottom): large and small hacksaws; saw with the “back”; Dawed with a narrow canvas. On the left near. Saw for finishing sawing.

For each workpiece. Its own saw

The hacksaw saws quickly, but a wide step of the teeth leaves a rough mark in the soft material. On the other hand, it would be difficult to saw a thick beam with a saw for a final sawing.

In a word, the material and tool should approach each other. Only then can you count on high.Quality work and get even, without defects in detail.

We offer a brief instruction: which tree you need to process which wood.

How to protect the saw from damage

Any saw (especially its cutting edge) should not in contact with other tools during storage. From such a neighborhood, she can fail.

If the saw does not have a cover, then a simple way will help protect its teeth from damage. In a piece of the hose, a slot of the desired length is made, after which the hose is planted on the saw blade. A hard hose covered from the inside with a cloth is best for this purpose. It holds tightly on the saw canvas even after repeated use.

If the longitudinal sawing is carried out in large volumes, then it is better to purchase a disk saw. Do it with a hand saw. You get. This is the first, and the second: the information that can be gleaned from the texts in the frame is incomprehensible for a beginner, and for a professional it is useless.

Basic manual saws

Any home workshop should have at least three or four saws of different types.

  • A hacksaw with a wide canvas for a rough sawing of large.Sized parts and blanks. The longer the canvas, the faster the work is going. However, for the same reason, the mobility of the canvas itself increases, which is why the saw, as they say, leads to the side. Therefore, it is important to carefully monitor the cutting line, avoiding its deviations from the marking. The novelty of recent years is the teflon coating of the hacksaw canvas, which greatly facilitates the sawing of fresh wood, and also protects the saw from rust.
  • The saw with the “back” differs from the usual hacksaw not only in that it has a hard nozzle, which “extinguishes” the fluctuations of the canvas, but also smaller, closely standing teeth. Such a saw allows you to make a clean and thin cut.
  • Drink for finishing sawing provides an even and neat cut.
  • The saw with a narrow canvas is designed to cut rounded parts and large holes. The basic rule of caring for any saw: its canvas should always be dry and clean. The teeth of the saw. Even hardened. Should be hidden regularly.

How to saw correctly

You must always cut from the cutting side, close to the marking line. This applies to both gross cuts with a hacksaw and accurate sawing saws with small teeth.

Further, it is very important that the processed workpiece has a stable support in the form of a workbag of workbag or ordinary desktop. For large blanks, it is better to use goats.

In the process of sawing, the part must be held hard all the time with a hand (a large.Sized workpiece. Also with a knee). In other words, only a saw should move.

Sawing begins with the first short movements at an angle from 30 to 45 degrees. Only after the saw canvas entered the wood and fixed in it, you can start working with a saw for the entire length of the canvas.

At the edge of the cut, saw only short shocks. This will avoid clamps on the bottom of the workpiece.

I drank along wood fibers. Always a “critical” situation, especially if wood with large fir. The saw wants, of course, to follow the path of the least resistance, and if it is not restrained, she will begin to “walk”. That is, in such cases it is necessary to press the saw more than usual, which, in turn, requires the most stable position of the workpiece.

With large transverse cuts, an ordinary hacksaw can jam. In such cases, it is better to use a saw for longitudinal sawing with highly divorced teeth. Only it must be taken into account that the cut of the cut will be much thicker than the saw blade.

Drinking fresh or raw wood will become easier if the saw canvas grease with wax or soap.

Hacksaw for longitudinal sawing wood

The blanks are tightly pressed to the tribe, its right edge directs the saw.


When processing small blanks, a greater help can be provided by a tsugla depicted in the drawings below.

To make it, you need a piece of a carpentry slab in size of about 20 x 30 cm and a thickness of 2 mm, as well as two chips, which must be fixed on the stove as shown in the figure. To prevent the curvature and break of the stove, the strips must be placed across the direction of its core layer.

How to work with a circular

The lower bar of the tsugla rests on the edge of the countertop and thus sets the correct direction of the cut, the shortened upper bar provides good centering of the saw.

If you have to saw long boards or strips, then the second tsugla will not interfere, which will be an emphasis for the other end of the workpiece.

Consider the two ways suitable for us: cut the logs along and across

  • And the longitudinal method is used to dissolve logs on boards, beams, rails. For this, many devices are used in production. We will consider how you can cut a log at home, yourself.

So, we have already removed the bark from the log, so we proceed to the following steps:

  • We fix the log on the guides or bed
  • We saw off the hump on one side to get a flat surface
  • We turn the log by the flat side to the bed and remove the second horseman
  • Next, we dissolve the log onto the boards

Slinging logs on boards at home

Many for sawing logs make a sawmill with their own hands. Consider the two main options for their manufacture.

  • From metal plates and squares, weld the frame, at its lower part, attach the engine. In the upper part, put a shaft with pulleys. Then fix one or more disk saw on Val. Fix the guide of a metal square or a beam on the table. Pressing to the guides, serve a log and move forward. If you use one saw, then you need to attach a ruler on the surface of the table or mark the marking.
  • From the profile pipe and channel weld the frame. Attach a saw with a gasoline or electric drive on a carriage with a vertical feed. So that the dissipation of logs on the boards is as accurate as possible, attach the ruler to the vertical rack. As a guide carriage, use a rod or polished pipe. They are necessary so that the carriage moves vertically. Install a screw in the bearing, which will move the carriage when moving. Also, do not forget to prepare the clips for the log.

Dissipation of logs on the circular

When using the second option to work in motion, it is the saw on a specially attached frame. The log itself remains in place. If you use a saber’s saw, not a chain, then the process is slightly delayed, since it works only one way.

How to cut a log onto the boards of a chainsaw at home

The fallen barrel can be cut into churbaks on the ground if you plan to use wood in kindling and firewood. How to cut a log of a chainsaw across. You do not need to explain, here the technology is simple, the main thing is to fix the log so that it does not swing and does not move during cutting.

But if the trunk is good, you can cut the log onto the boards of a chainsaw at home and get absolutely free building materials necessary in your own farm.

In order to cut the log along the chainsaw, several devices are necessary:

  • Bed or frame where the log will be fixed. For its manufacture, a corner, a channel or pipe is used, thick enough to withstand the mass of the log.
  • Chainsaw with a nozzle. You can use a gas tank, a debarker, a vertical or horizontal nozzle. The most accurate and effective dissolution of the logs provides precisely the horizontal nozzle, but it can only be used when the saw length is no less than the thickness of the log. If all this is not, you can do without nozzle. It is enough to make two simple devices, with which the logs of the chainsaw will be cut on the boards will happen easily and simply.
  • Slinging the log onto the boards of a chainsaw can be independently carried out without preliminary emphasizing. It is easier to do it later.

Two Beautiful Blondes Cutting Dimensional Lumber On The Sawmill

Consider the easiest way to dissolve the log onto the boards, that is, without specialized nozzles. It is necessary to make two simple clamps, cooked (the best option) or assembled using bolted joints.

These clamps have a T-shaped shape and length of about 500-600 mm. Another plate or corner is attached to a short “stick” with the help of bolts, and there should be a slightly larger distance between them than the thickness of the chainsaw tire.

The clamps are attached to a homemade carriage carriage. When dissipating the log on the boards of a chainsaw with its help, the carriage will move.

Holes are made on the clamps. This will allow you to adjust the height with a longitudinal cut of the logs of a chainsaw.

The assembled design is installed on the frame. Before cutting the log onto the boards, install its special stand, so that, as necessary, it can be lifted. The best option is two car jack.

After the first cut of the chainsaws of the chainsaw occurred, it rises to the required height and the next cut is performed according to the same scheme.

How to cut logs onto the boards

As you can cut the log onto the boards? And is it possible to cut the logs onto the boards using a conventional circular? Below we will try to answer these questions and describe in detail the process of cutting logs on the boards using a conventional circular saw.

For longitudinal sawing of logs, a machine called a sawmill is usually used, in which strip saws stretched in a frame that make reciprocating movements are a cutting tool. On such a car, a log for one pass is applied to the boards. In this case, the log is fixed on carts moving along the rails. The log moves strictly progressively, without turning around its axis. The rails along which the trolley moves play the role of guides, so they are exposed quite accurately.

A similar longitudinal sawing of the logs on the boards can be performed using the circular, if you provide longitudinal movement of the log. It is clear that on the horizontal table of the circular, it is difficult to keep the round log in the right position. It will necessarily be rolled into boards when sawing, as well as “scour” right and right. This situation must be excluded. We will immediately say that on a round saw, as a guide, you do not have to count. On the contrary, the saw should be completely freed from the performance of such a role. Therefore, to fix the log in the right position, we came up with a fairly simple additional device. Fin. So we called this device when we adapted the circular for sawing small aspen logs during the construction of a Russian bath along with a ruler installed on the table (side guide), the fin really helped us.

Rice. One. How to cut a log onto the boards using a circular saw: 1. A clamp; 2. Spacer; 3. Fin; 4. Round saw; 5. Log; 6. Circular table; 7. Guide line; 8. Emphasis of clamps; 9. Laying; Δ. Thickness of the sawn board.

The thickness of the fin corresponds to the width of the cut, and the fin is installed with the possibility of adjusting its position. Dissolve the log onto the boards together. They begin to saw along the log, just pressing it to the ruler, that is, the way the boards are usually sawn. After the fin is completely in the cut, the last (from the end of the log) inserts the spacer with a thickness of a slightly larger cutter. A piece of a flat file came up as a spacer. Further, a special clamp-hand was installed at the end of the log, which, firstly, held the board by the log to the end, and secondly, for which it was convenient to pull the log. A jerk file, having a notch on both sides, was well held by the board “on the spot”, that is, the cut-off board did not shift from the vibration relative to the log. The peculiarity of the design of the clamps was that it had an additional jumper, which, when installing a clamp in the diametric plane of the log, when exposed to it with the hand, does not allow the clamp to turn up around the axis of the clamping screw. So that the cuts are parallel when sawing the logs, on the lower part of the logs form a bald (first with an ax, and then a shirt), which will determine the correct orientation of the cut at the beginning of the sawing. The position of the ruler. Its distance from the saw. Determines the thickness of the board. So, the presence of a ruler on the table, baldnesses on a log, as well as a “fin” and clamps will ensure the success of the sawing. One of the “sawmills” pulls logs by the clamp, the other presses the log to the ruler.

If you have to work alone, you will have to build something else. Firstly, in front of the machine (where you are going to push the log from), you should install a stand under the log (goats) with a height equal to the height of the machine table. Secondly, in front of the saw on the machine table you will need a clamping device that can provide contact of the log with the ruler from the beginning of the sawing to the end. The clamping device must reliably hold the log at the ruler, without creating a large resistance to the extension of the log during sawing. Such a device assembled from a small wheel with a pneumatic bus, for example, from a children’s bicycle, and a swivel lever is shown in rice. 2.

The lever is easiest to make from parts of the frame of the old bicycle. Dischard and lower pipes are drank from the brown node, leaving only a “chain” fork, from which, in turn, the rear fork is separated. The front fork, having previously removed the tips with the feathers, weld to the “chain”. On the rod of the front fork, put on the handle from the bicycle steering wheel. In the middle of the “chain” fork (opposite the front fork), the plates with slots for installing the wheel axis are attached (welded) to its feathers (see). Rice. 2). In addition to this part, it will be necessary to make a rotary nut. A support for a crush screw, a screw itself, a traverse and an axis of a lever. You will need some fasteners (nuts, washers, pins) shown in rice. 2.

Before sawing the logs on the boards on it forms bald (from below and from the sides). Side Brees of Logs ensure the strictness of the direction of its progressive movement during sawing and the constancy of the force of the clamping wheel, which makes the work calm and confident. Before the cutting, the wheel is pressed manually to the log, simultaneously rotating the screw for the flywheel. The screw in this device serves only to fix the position of the lever with the wheel, therefore it is equipped with a small flywheel, for example, from a water tap. This makes it possible to dose the force of exposure to the wheel on the log “to the touch”.

Now the market offers a large assortment of woodworking technology. There are many varieties of moto and electric saw. If you are going to dissolve the logs onto the boards for a long time and seriously, but you do not have the machine yet, think about the use of a saw from a motorcycle as a saw. Its drive will have to be placed under the machine table, like a circular, and install the saw vertically above the table. With the help of such a machine, you can cut logs on the boards of a much larger size and prepare lumber for doors, windows and other large products.

Tools for cutting logs

Tools and methods of cutting depend on the total volume of logs, such indicators as length, thickness. In addition, you need to take into account the quality of the future lumber. Logging of logs provides for work with various tools and specialized equipment. To obtain a small volume of lumber at home is suitable manual

A method of processing logs using a chainsaw or traditional hand knives with teeth for longitudinal cutting.

Pylorama. Is this not the most famous type of saw equipment. This is a woodworking machine that has strip saws. Longitudinal sawn beams, for example, is trimmed, board

Or a beam. Floacular work allows you to process logs with a diameter of 15 to 80 cm and up to 7 m long.

Slinging logs into boards using disk (circular) machines is carried out using a circular saw. Such equipment can be single (single.Disc) and multi.Digger (multi.Disc). Devices containing one disk are suitable for processing low and low quality raw materials. Large diameter round blanks can be cut using machines with several blades.

The most popular today. Ribbon sawmills. They are of two types: vertical and horizontal. Cutting tool in such equipment. This is the belt that is put on the pulleys. Working with tape saws guarantees high.Quality elongated and mixed lumber, such as boards and bars. In this case, the smallest amount of waste is formed.

In large industrial enterprises, mowing mowing fishing line is used for cutting wood. They allow you to get very high surface quality and accurate geometry of the final products. These Kosovo Kosille fishing lines are characterized by high rates.

In addition to all of the above equipment, such types of highly specialized sawmills as a mark, edging, strichcopod and other types of machines are also used.
