Planing wood - processing blanks before the right size and creating on her equal and smooth surfaces.Planing is carried out using various plows (planing tools). Among the plows are the most common sherhebeli, planers and jointer

With these tools, shavings are cut from wooden workpieces.

The cutting edge at the sherbel’s knife is arched, convex, and at the plane and jointer - straight.

Sherhebel   perform primary, more rude planing surfaces, but planer - final, fine. « Sherhebel » - german word origin, what means "Plow for rough cutting ".

The planer consists of pads , the knife , wedge , pens . The planer is intended for cutting fine chips and obtaining smooth surfaces on wood, as well as cutting the workpiece to the desired size.

Plow pads can be wooden, metal or combined.

Joiners are much longer than planers. They are comfortable to get smooth, flat surfaces.

The cutting part of all carpentry tools is wedge-shaped. For example, a planer knife in its cutting part is sharpened in the form of a sharp wedge. Two surfaces of the wedge at their intersection form a sharp cutting edge. This cutting edge cuts the wood fibers, and the front surface of the knife bends the cut layer in the form of chips.

Before planing, check that the tool is set up correctly. For a correctly installed knife, the blade is located above the sole of the block without distortions and protrudes 1 ... 3 mm at sherbel   or at 0.1 ... 0.3 mm for the planer.

The workpiece to be mounted on a workbench, clamping or jamming between the stop and the wedge so that the cut side is facing up. With their right hand they take the plane for the handle from the back of the block, and with the left - for the block or handle from the front. A planer is mounted on the workpiece with the blade down and pushed forward. At the beginning of planing, they press on the front of the planer, and at the end - on the back, so that the surface to be machined is flat.

With the return movement of the plane, it is raised above the surface. So, making a movement forward and backward, they gradually cut the surface to be treated until it becomes even and smooth.

If the fibers on the work surface are pulled up, then the part should be planed on the other hand.

The plane must be held tight so that the hands do not slip off and hit the sharp side ribs of the workpieces. In this case, bruises and cuts in the hands are possible. The workpiece stops should not protrude above the work surface.

Quality control of planing is carried out using a ruler or square to the clearance.

Rules for safe work when planing:

but). Securely fasten the workpiece to the workbench.

b) Work a planer with a well-sharpened knife.

in). Do not check the sharpness of the blade and the surface finish with your hands.

d). Only use a wooden wedge to clean planing tools from chips.

Updating knowledge and fixing individual difficulties in a problematic action.

In order to actualize knowledge, a brief conversation is held with students, during which the following questions are asked:

1. What does it mean to cut a timber blank? (Cognitive UUD - to acquire new knowledge in the process of observation and reasoning)

2.What is the workpiece planed for? (Cognitive UUD - to search and select the necessary information for solving a training problem in a textbook, encyclopedia, Internet).

3. What types of planers do you know? (regulatory UUD - to independently study the tool for sawing and planing).

4. Who is such a joiner? (regulatory UUD - independently find the necessary information in the textbook)

Formulation of the topic of the lesson.

What do you think we will learn today?

Having clarified the opinion of the children, the teacher clarifies the purpose of the sherbel and planer (updating students' knowledge, regulatory UUD - goal setting)

Practical work

The teacher instructs students, organizes the updating of methods for studying actions sufficient to build new knowledge.

Trial action (task) - to process wood blanks with a sherbel and planer.

One - treats with a shekhebel.

The second - processes a plane.

Third - conducts quality control.

(UUD communicative - cooperation, performing different roles in the group)

The teacher checks the correctness of the assignment, identifying difficulties in the trial action.

Fixing difficulty:

Incorrect planing (ways to solve the problem)

Way out of difficulty:

Once again, the teacher tells the students about the methods of planing with a planer and sherbel, thereby organizing the students to investigate the problem situation (UUD - communicative, joint solutions to the problem)

Reflection of learning activities

At this stage of summarizing the lesson, the teacher asks the children questions, answering which he can judge the assimilation of this material.

Questions: - What tools and devices are used for planing wood? What is the difference between sherbel and planer? Why is woodworking planed?

What new knowledge have you received for yourself?

Can knowledge acquired today be useful in life?

The teacher invites the boys to evaluate their work in the lesson. (UUD personal - an adequate understanding of the reasons for success / failure in educational activities.)

Homework: Find on the Internet information about other tools for planing wood (grind, zenzubel, humpback, faltsgobel, zinubel).

Planing. In order to give the wood blank the desired shape and size, as well as to obtain a flat surface, the planing operation is performed. It consists in removing thin layers of wood in the form of shavings from the surface of the workpiece. Planing is carried out with manual planing tools - planers with wooden or metal blocks.



Depending on the purpose, planers have cutters of various designs. So, for a planer for clean planing, the blade of the cutter is sharpened in a straight line, and for the sheher - planer for the initial (rough) planing - the cutter has a narrow rounded blade.

Before work it is necessary to check whether the tool is adjusted. For a correctly installed incisor, the blade is located without distortions and protrudes above the sole: for sherbel - 1-3 mm, for planers - 0.1-0.3 mm.

When planing, you must observe the correct grip of the tool and the working position. It should be touched to the full extent of the arms, sending the plane forward with force. At the beginning of the movement, the plane (sherbel) is pressed harder with the left hand, at the end - with the right.

Quality control of planed surfaces is carried out using a ruler or a square to the clearance. Quality control of planed surfaces is carried out using a ruler or a square to the clearance.

After sawing is finished, the board or bar should be planed to smoothness, remove roughness from the sawn surface. This operation is called jointing and is performed on a planer or electric planer, and manually - by one of the representatives of the planer family. The simplest planer has a wooden case with a handle, a knife and a wooden wedge for fixing the knife.

A modern metal planer has devices that make it easy to regulate the release of the knife blade, which determines the thickness of the removed chips, and the angle of inclination of the knife to the planing plane, and the width of the slit for chips, and the parallelism of the knife blade to the plane of the board.

Planing begins with a sherbel, which allows you to remove a thick layer of wood, and can be planed up and down thanks to the oval shape of the blade.

A planer with a single knife smoothes out an uneven surface after sawing or sherbel, and with a double knife (double planer) it is good for fine planing, planing of butt ends, bulging and twisted sections. In such a plane, the second knife, the chipbreaker, prevents teasing, flakes and spalls.

To grind the burrs, a grinding point is used, it has a short body and an increased cutting angle, which provides thin chips.

The Tsinubel is intended for the formation of grooves and the fleecy surface of the tree (for gluing), therefore, its cutting angle is very large (80 °), and the blade has the shape of a comb.

If you insert a regular knife into the casing of a zinubel, then it can be used as a grinder.

For planing the ends, an end plane is used, in which the knife blade is turned at an angle to the direction of planing.

Zenzbel is designed to sample a quarter. The knife at this plane has two cutting faces - the lower and side - and a side hole for the release of chips. As with the end planer, the lower blade of the knife is turned to the cutting plane at an angle, which improves the quality of cutting.

Mechanical planing of wood is carried out using manual electric planers and special machines. Manual electric planers are used for planing logs, beams, boards, floors and various blanks of carpentry, as well as in cases where the workpiece is not possible to bring to a stationary planing tool.

For any planing, especially when roughing, when a thick layer of wood is removed, it is necessary to determine the direction of the fibers, so as not to plan the look. This is determined by inspection (the fibers should come to the surface in the direction of movement of the tool, i.e., from the joiner) or by trial planing if the fibers are invisible.

When mowing with a scherbel, you can get chips so deep that the workpiece will be damaged. Rough planing is performed with large allowances (up to 5 mm) with a sherbel, with small (1 - 2 mm) planers with one knife. Scherhebel is planed obliquely to the longitudinal axis of the board or bar. Knife release 2-2.5 mm. In wide boards, when crossing the line of the core, as well as in slanting, half of the board may turn out to have a different exit of fibers, so you should either turn the board over or plan it on yourself. If there are knots around which the fibers always form a curl, the knife release should be minimal and the knife itself very sharp, otherwise deep punctures and flakes may appear, because of which it will be necessary to remove a thick layer of wood again over the entire surface. It is not recommended to plan narrow bars and edges with a sherkhebel, since it is difficult to notice the borders here, and the bar will be re-cut.

Wood drying

The wood intended for work should be dried up to 10 - 16% of humidity. Dry wood is better processed.

Wood drying is a very important technological part of the whole process of processing and manufacturing various wood products, because it depends on the drying what the tree will be, how it will look and how it will be processed.

The more competent the wood will be dried, the less there should be cracks. The wood must be dried very well, which may take a lot of time, but the finished product will be less prone to cracking and drying out.

Drying can be done in several. Atmospheric or free-air drying is simple and affordable, but a tree located under a canopy that protects it from rain and direct sunlight dries very slowly - from several months to several years. In summer, wood dries better than in spring, autumn and winter. But if the summer is rainy, it not only dries poorly, but can also become moldy and even rot. In favorable weather, the wood can be dried to an air state of 12 - 18% humidity.

The trunks of soft hardwood trees bark, that is, remove the bark from them, and lay on racks. Sometimes strips of bark are left from the ends. The same rings at equal intervals are left in the middle. From the trunks of hardwood trees, such as apple trees, maples, bark is not removed at all. To prevent the wood from cracking due to uneven drying, the ends of the trunks are painted over or whitened. Putties that close the pores of wood are made up of a mixture of drying oil and lime-fluff or wood tar and chalk. When drying small trunks, the ends are covered with a thick layer of thick oil paint.

Digestion of small pieces of hardwood in oil and varnish not only prevents the appearance of cracks, but also enhances the decorative expressiveness of the material. Billets for small carvings from apple, boxwood, pear, and oak are boiled in natural linseed oil, linseed cotton, wood (olive) oil. During cooking, oil displaces moisture from the wood into the air, filling the intercellular spaces. The wood boiled in oil or oil is then dried at room temperature. Well-dried wood acquires additional strength and moisture resistance, is perfectly ground and polished.

Digestion of wood in salt water also prevents its cracking. In addition, salt reliably protects the wood from the penetration of putrefactive microbes. In the woodworking workshops of timber industry enterprises that produce troughs and other diced dishes, finished products from linden, aspen and willow are boiled in a 25% solution of table salt.

Small workpieces made of hard and soft wood can be processed at home. Raw wood is placed in a deep pot and filled to the brim with salt water at the rate of 4 - 5 tablespoons of table salt per liter of water. The wood is cooked over low heat for two to three hours, then taken out of salt water and dried at room temperature.

Burrowing wood into shavings is a well-known and reliable method of drying wood used by turners and woodcarvers. Raw turning parts are immediately buried by the turner into the shavings obtained by turning or pre-harvested. A woodcarver buries an unfinished carved board or sculpture into shavings. They dry evenly with chips. This measure relieves the product from warping and cracking, especially with a long interruption in work.

Masters-drevodela always were inexhaustible to fiction, especially when it was necessary to get solid material. Noting that even in severe frosts inside the dunghill, a rather high temperature is constantly maintained, they began to bury oak ridges in it. In spring, the ridges were washed in running water and dried under a canopy in the open air.

Chamber drying is widely used in woodworking enterprises. In special drying chambers, wood is treated with superheated steam and flue gas. The wood dried in the chambers has a room-dry moisture content of 8-12% and is used for carpentry, turning and carving. From three days to a week it is required to dry softwood, such as pine, linden or spruce. From two weeks to a month, solid wood of oak, beech or elm should dry in the chamber. But with chamber drying, the appearance of cracks is not excluded. Therefore, scientists are constantly looking for more advanced and faster ways to dry wood.

In recent years, drying chambers operating at high frequency currents have been created. In such chambers, wood is placed between two brass grid-electrodes. The electrodes are supplied with current from a high-frequency generator. In an electric field, wood dries almost 20 times faster than in a steam chamber. In this way, valuable hardwood is dried.

It should be said about another original method of drying wood - drying on a cement floor, based on the ability of concrete to intensively draw moisture into itself. Wet wood is laid on a dry concrete floor. During the day, each workpiece is turned over so that alternately one or the other of its face rests on the cement floor.

Successful drying of wood depended largely on the size and shape of the workpiece, the presence or absence of sapwood. A craftsman who knows the structure, physico-mechanical properties of wood, with the help of an ax, saw, drill and chisel, could at his discretion direct the drying process in the right direction.

It is well known that it is especially difficult to dry logs, ridges and lumber having a core inside. As a rule, when dried, they crack almost to the core. The logs of many chopped buildings are usually dotted with numerous cracks. However, you can still find log cabins that do not have any noticeable cracks.

How did carpenters dry logs so well? It turns out that there are still cracks on the logs, only they are hidden from our eyes. For each log there is one large crack, but they are skillfully disguised inside the log house. Before drying along each log, the carpenter made a notch with an ax. The depth of the notch was approximately one third of the distance from the surface of the log to the core. After the wood dried, one deep crack formed at the notch site, and the remaining sections of the log remained smooth. One large crack seemed to absorb dozens of smaller ones, concentrating shrinkage in the notch zone. Stacking logs in a log house, carpenters placed them with cracks down. According to the same principle, the wood-cutters of India dry boxwood, which is known to be very hard and prone to severe cracking. Boxwood block is sawn to the core, due to which shrinkage during drying is always concentrated in the cut zone.

Chipped wood is known to dry quickly and without cracks. If you split a log or ridge in half, you get a plate (half). The half dries up much faster than the ridge, not only because its mass becomes half as much, but also because air is opened to the cut annual layers. If the half is dried unevenly, then a deep crack can go from the core. Splitting a half in half, get a quarter (according to the old "quarter"). Unlike a plate, a quarter very rarely forms cracks when drying.

The properties of chipped wood were well known and skillfully used by master carvers from the Trinity-Sergius Posad of the Moscow province. They split the lime ridge, depending on its thickness, into four or eight parts through the core. Perhaps this technique, which arose when it was necessary to avoid cracking wood, to some extent suggested a plastic solution to many carved toys.

Hard enough to dry hardwood with a core. When dried, it cracks severely. Deep cracks reach almost the core. For example, freshly chopped apple tree wood is susceptible to severe cracking. But even the trunk of a dried apple tree is dead wood after sawing into short ridges and ham, it is covered with numerous cracks. The apple tree has a light sapwood and a dark core. Masters especially value the core. The core wood is harder and drier, and its pores are filled with a special preservative. Sapwood, on the contrary, is loose and very saturated with moisture. When drying, the ridge cracks in the first place, and then the core. To preserve valuable core wood, sapwood is chipped with an ax and butt ends are greased with paste. After removing the sapwood, the wood dries fairly well, almost without forming cracks.

Raw wood is a lot of trouble for sculptors, who most often have to deal with ridges of rather impressive sizes. In order not to depend on the capricious inconstancy of the wood in the logs, some sculptors glue blocks of pre-dried bars that are necessary in size and configuration. Glued blocks do not give in to warping and cracking, but the violation of the natural direction of the wood layers that form the texture pattern is often detrimental to the artistic merit of the sculpture. In a sculpture made of a whole ridge, and not of a glued block, the texture, on the contrary, emphasizes the shape and makes it more expressive.

The craftsmen noticed that if the core was removed from the ridge, then the appearance of cracks can be almost completely avoided. A hole with a diameter of about 5 centimeters is drilled in the workpiece along the core. When drying, moisture is simultaneously and evenly removed not only from the upper, but also from their inner layers of the ridge. Having completed work on the sculpture. the holes are clogged with wooden corks.

Wood was dried in the woods right on the vine in spring and summer. Around the trunk of the tree intended for cutting, a wide ring of bark was removed. Moisture from the soil ceased to flow into the crown. The leaves and needles absorbed the moisture remaining in the trunk, which evaporated simultaneously with drying. A tree with a dried trunk was felled, branches were chopped off, and then they were cut down, that is, sawn into logs. Nowadays, in this way, harvesters dry the pine before rafting down the river. Drying the trees on the vine increases the buoyancy of the fused wood, and therefore reduces its loss in transit.

In the spring, when the young foliage was gaining full strength on the trees, the Bogorodsk craftsmen went to the forest to harvest linden wood for carved toys. Twigs were cut off from the dumped linden and the bark was removed from the trunk about two-thirds of the length of the whole tree. The top of the tree with branches, branches and leaves (crown) was left untouched. The considerations were very simple. The foliage does not wither away at the sawn tree immediately, but continues to fight for life for a long time, as if by powerful pumps, drawing in the life-giving moisture located in the tree trunk. In two weeks, this natural pump pumped so much moisture out of the barrel that it would take several months to remove it during normal drying in the open air. After two weeks, the linden trunk was sawn into ridges up to one and a half meters long. The barked and dried linden ridges, the so-called lootos, were brought home and dried in the courtyard under a canopy, laying them on a floor towering above the ground. By autumn, linden wood was already quite suitable for all kinds of carvings. Part of the wood was put into operation, and the rest was continued to dry out in free air.

Wood drying by steaming was used by craftsmen in the distant past, since the Russian stove was invented, which became the prototype of a modern drying chamber.

If for some reason it was not possible to procure wood from spring, it was dried in Russian ovens in a short time. Steamed wood in large cast irons. Raw wood was laid in cast iron, and a little water was poured into the bottom. Then the cast iron was covered and placed in a melted furnace. To prevent the heat from leaving the furnace, it was closed with a damper. In the morning, the wood was removed from cast iron and dried at room temperature.

We used another, simpler method of drying wood. After another firebox, ash was scooped out of the Russian oven and the floor was cleaned, on which wooden blanks were placed on the priest. Tightly closing the shutter, the tree was kept in the oven until morning. By morning, the wood dried well and at the same time acquired a beautiful color. The raw white linden after steaming was dyed golden, and alder wood was light chocolate.

Drying logs in an upright position on dry land is known in the southern regions of our country. For example, Uzbek carvers dried wood under a canopy in the open air. The logs intended for drying were placed vertically, so that the bottom end rested on dry soil. Moisture in the logs gradually descended along the fibers down the capillaries and the dry earth eagerly absorbed it.

Drying of wood in the ground and river sand. From the trunk of a freshly cut tree, a rough workpiece is first cut out. Then it is buried in the ground somewhere under a canopy, so that rain can not moisten the soil. In the ground, a tree can withstand several years, but more often it takes only one year. After a certain period of time, the workpiece is torn out of the ground and dried in the room. Duration of rest is determined by the state of the wood. The color of the wood, the nature of the sound made by the workpiece with a light tapping on it with the knuckle, give the experienced craftsman accurate information about the readiness of the wood for further processing.

Small pieces of hardwood can be dried quite quickly artificially in river sand. At the same time they acquire a golden brown color.

An interesting decorative effect can be achieved by drying already finished carved products. A layer of clean river sand is poured into cast iron. Billets are placed on top, which, in turn, are covered with a new layer of dry sand. Thus, cast iron is filled to the top, making sure that the workpieces do not touch its walls. Loaded cast iron without a cover is placed on the stove. The closer he stands to the burning wood, the faster drying will go. But at the same time there is a danger that the wood will begin to smolder after some time. At the same time, if the iron is too far from the fire, the wood will dry slowly. The optimum distance from fire to cast iron is determined empirically. As the wood dries in the areas facing the fire, a golden tan gradually appears. It smoothly turns into a natural color, which has a wood blank on the opposite side. Often this is the effect they achieve by decorating finished carvings. But if you want to get a uniform color, the cast iron is occasionally rotated around its axis, substituting one side or the other for fire. If they want to get clean, dried wood (without tanning), cast iron with sand and billets is put into the furnace after being smoked overnight. Wood can be dried in the sand on a stove or on a fire, using cans, old pots, buckets instead of cast iron.

From written sources it is known that ancient Greek sculptors dried valuable wood by digging in dry rye. Drying of wood in grain was well known in Russia. A wooden blank was buried in the grain closer to spring. For several weeks, the grain absorbed all the “forest moisture” from the wood. The wood thus prepared was kept at room temperature, and then boldly put into operation, without fear of cracking. It was believed that drying the raw wood in the grain a few weeks before sowing beneficially affects the quality of the seed. The grain, filled with life-giving moisture, seemed to wake from hibernation and sprouted faster, once in the ground.

To get a flat surface, the details are planed. When planing, a thin layer of wood - chips, is removed from the surface of the workpiece. For manual processing of wood blanks with planing, we will use a planer and a shekherbel. Let's compare the two tools. What are the differences. Cherkhebel serves for preliminary (rough) planing of workpieces. The plane is intended for final (fair) planing of workpieces.

Before planing, the workpiece is installed on a workbench. How to do it? The plane is placed on the workpiece with the sole and begin planing. In order to make the planed surface smooth and even. It is necessary to fix the workpiece so that the direction of the wood fibers coincides with the direction of movement of the planer during planing. At the beginning of planing, they press harder with the left hand on the front of the planer, and at the end of the movement - with the right hand on the back. If the tap hole is clogged with chips, then it must be pulled up from the tap hole or cleaned with a sliver. The quality of the planed surface is checked with a ruler, applying it in different positions.
