How to make a boomerang of paper or tree: step-by-step instruction. BUMERANG.

Not everyone knows that the boomerang is essentially a kind of throwing wooden weapon. But those times when it was used as a weapon, long gone. Today is a toy that not only children want, but also adults. We will tell you how to make a boomerang do it yourself.
Boomerangs were widely known due to the ability to return to the place from which the man made a throw. But there are also such boomerangs that are not returned (combat).

What other boomerangs exist?

A - battle boomerang; B - "saw pil"; In - Boomerang "Kylie", which, like "Pil-Pil," knows how to return, but only in the case of a throw against the wind; R - sports and hunting returning boomerang; D, E - Multiboble returning boomers.

Boomerang do it yourself

It will take:

Cardboard sheet;
Plywood or tree;
Varnish or paint;
Lobzik;
Plane;
Sandpaper.

First of all, you need to draw the selected boomeranga model exactly in a natural value on a dense and thin cardboard sheet. It is recommended to select the size of the leaf of 50x60 cm. After that, it is necessary to transfer the grid of the square to the cardboard, which is 50 mm.
Next, redraw on it the outline of the boomeranga from the drawing shown in the picture.

How to make a boomerang from plywood

From the received template, drink a blank from plywood. Its thickness is 10 mm.
Now you need to handle the workpiece. This should be done by a small-sized batch in vice or with the help of a device that is shown in the image (g). Boomerang need to oversight, starting with the middle, moving towards the edges of the blades. Their end must result in a thickness of 6 mm. The blades must be absolutely the same in shape. To simplify the task, you can make counterbasks blades from plywood and apply them to check the correctness of the forms.

The surface should be completely smooth, so the next step will be grinding. To do this, you can use sandpaper. After grinding, almost ready-made boomrang is covered with primer, and after varnishing or paint. It is best to use bright paint so that the boomerang can be seen from afar and easier to find when falling. In addition, parquet varnish can be used for the coating, which retains the aesthetic structure of the product. This is how relatively easy it is possible for an hour - two make a boomerang with your own hands.

How to make a boomerang from a tree

If it is possible, it is recommended to make a boomerang of wood. For this, as a rule, dried bits and roots are used. It is important that the tree is dense, heavy and well dried. For the manufacture of boomerang suitable: oak, birch, beech, linden. The manufacturing process is exactly the same as in the case of plywood. But it should be remembered that the tree will deter much faster plywood, so it needs to be covered with varnish or paint especially carefully.

If when creating a boomeranga, you have complied with all the rules, it will have excellent flight qualities and beautiful external species. How to make a boomerang with your own hands we figured out, now you need to deal with how it is correct to run.

How to run boomerang

1. Place for training
To run the boomerang for the first time, despite all the seeming simplicity, it is quite dangerous due to unpredictability, so it will take some caution and attention. Boomerang can be completely in someone to get, so you should not begin experiments in crowded places. The optimal place for training dexterity and accuracy - meadow or glade with a radius of 40-60 meters (the more, the better). A soccer field or a wasteland can become such a melayer.

The start of the boomeranga is specific to the fact that the trajectory of its flight is eight. Therefore, the throwing boomerang man should reckon it only from the center of the place selected for training. The projectile will fly forward by making a loop before the thrower. It will notice it will return and make the same loop already behind the thrower, thereby forming the eight, the execution of which depends on several parameters - the strength of the throw, the quality of the boomeranga, the thrust reader.

2. The key to success in the correct grip
Boomerang has two main surfaces. The convex facial side, which, as a rule, caused a drawing, creates its effects when rotating. The back side, in most cases, is flat, it can also see the drawing on it, but with proper throwing, usually, you can only see the front side.
Boomerang is customary to keep like this: the thumb always lies on the front side. Keep boomerang correctly - means keeping his face and see a good picture.
Boomerang can be kept and the wing back and the wing forward. It is not fundamentally and in any case correctly - as you will be more convenient.

Boomerangs are light and heavy. Type can be defined independently - the hand will tell you exactly what boomerang you hold.
Easy boomerang in hand needs to be fixed with three fingers - it is pressed by medium, large and index fingers (it should be reminded that the thumb with the correct capture should always lie on the front side).

The heavy boomerang hold three fingers is quite difficult, so it must be fixed in the fist, right up to the mother's, i.e. The grip comes out by four fingers, so fixation is pretty tough. You can capture and deeper, but when you throw the boomerang then it will be inconvenient, so capturing heavy boomerangs is not recommended deeper than four fingers.

3. What tilt should be in hand
Many newcomers on the subconscious level launch boomerang, tilting it as a sickle, which the grass is cut, almost in parallel to the Earth. It is absolutely wrong. In the boomeranga, the aerodynamics is designed so that it is correct to throw it - it means to throw almost perpendicular to the horizon, at the same time the slope to the horizon line should be to the right of the imaginary perpendicular. Release boomerang during the throw should be at an angle of no more than 45 ° to the horizon line.

It is possible to come to this experimentally and independently - with an excessive slope, the boomerang will sharply take off, after which it is also sharply dive to the ground before the thrower. If the throw is performed at an angle of more than 45 °, then the boomerang will never even return to the thrower.

4. What should be a throw
Boomerang should throw sharply and strongly. When you start the boomeranga, it is necessary to take into account the fact that the projecture requires the force not only for flight from the thrower, but also for the return path and the loop behind the thrower. Therefore, throwing should be extremely strong and sharp, especially if for training you use a real wooden boomerang, and not a toy plastic copy. As a rule, the first throws are timid and careful, especially if a woman or child throws. But you should not be afraid! Any high-quality boomerang is designed for a powerful throw, because if you throw it weakly, it will lead to a rapid fall somewhere along the trajectory, which is not very good for him.

5. Spinning boomerang
During the first throws, there may be a situation that you, as you may seem, throw a boomerang sharply and strongly, but it flies all the same smoothly, without spinning as required. In this case, you need to master some spin skills. If you throw the projectile correctly, it will be twisted as quickly as a propeller - the drawing is alive in a solid circle, it will not be visible to the blades. To ensure maximum twist, competent capture is extremely important. In addition, the boomerang should not be dragged too much in the fist (the correct capture was described above).

There are many ways to twist a boomeranga, but we will stop at the simplest and most common.
So, waving and sharply throw, but at the very last second before the release of the boomeranga, you do not let go of your hand, but quickly stop it, as if shelter. Many of us used mercury thermometers, so such a movement is familiar to everyone - it completely repeats the shaking of the thermometer.
With such a throw, we leave the boomerangu a kind of footboard, follow the running foot and it, stumbling, rolls the cubera. Drilled by such a stopper boomerang will be scores stronger.

6. Accounting by wind
How to launch boomerang we figured out, but the wind should be taken into account. The wind is not a major factor that affects the flight path not only boomeranga, but also all air shells and devices. Its influence should be taken into account when throwing no less than the force of the throw and the correct grip. If the wind is very strong, a sharply changing direction and power (intermittent), the training is better to postpone and work out once again the theoretical part. Training is better to start in calm windless weather or with a slight, non-changing wind direction. If you make throws in the wind, then the throw is recommended to direct the wind towards the wind a little right of its movement. With such a throw, the wind will help the boomerangu back to the thrower. Among other things, the wind has a strong impact on the accuracy of the return of the projectile, because the behavior of any aircraft depends on the existing air flows. With the wind can be made friends, but it comes only with experience and after numerous workouts. From the first time, comprehend this art is simply impossible.

Let's summarize

Note the main rules for handling boomerang:

Throwing boomerang follows from the center of a deserted place having a radius of at least 40-60 meters;
With a literate seizure, the thumb should be on the front side;
When throwing the boomerang, you need to tilt to the horizon line from 90to to 45o, otherwise the projectile will simply stick to the ground;
The correct throw is a sharp and strong, wicked. Boomerang in this case is well spinning;
If you train in windy weather, then the throw must be directed against the wind a little right.

Only perseverance and patience, purposefulness and perseverance will help you to gain a certain experience and learn how to throw boomerang correctly. It can fly perfectly in winter, and in summer, the ability to practice can always be accessed, but it is better not in conditions of deep snow.

Make a wooden boomerang is an ancient method of communication with the world and the surrounding nature. If you will persistently train, you will soon be able to understand the wind, air flows and other elements of nature. For many years, many people successfully comprehended this art and continue to study him.

You have successfully managed to familiarize yourself with the theoretical part, after reading this guide, therefore it is time to move to the important and main part - practical. Practice and experience will teach you the art of throwing boomeranga, delivering a unique pleasure from the union process with the outside world.

From AlexGyver, four-blade boomerang from undergraduates. Make such a boomerang can almost any, materials used in homemakes are available to everyone. This boomerang begins to work immediately after the assembly, if you follow all the recommendations and instructions, and small refinements that will be mentioned will help improve its characteristics.

So, for the manufacture of a four-odd boomerang, the author used the following materials:

Two rails, length 30 cm, width 4 cm, thickness of about 7 mm.
PVA glue on wood or liquid nails
Auxiliary tool - file, hacksaw, knife and sandpaper

Making boomeranga

To begin, it is necessary to prepare the material, for this you need to cut off the rails of the desired size and is well treated with their sandpaper. The author recommends not to use too dry wood, as the heavier it will, the better the boomerang will fly.

After preparing the material, you need to place the workpiece. They will be attached to the cross on the cross, if they need to fasten them in the same plane, for this it is necessary to make grooves in the center of the plane so that it would go to another. We place the rails as shown in the photo below, the dimensions are arbitrary, markup from the end, should be equal to half of the rack thickness.

The next step, you need to make rugs using a metal hacksaw in the places of markup, it is necessary to do it on the front side of the rail to the middle, it is necessary to do it with two blanks.

After all manipulations, both skimmets should be perfectly entering each other, forming one-piece and smooth surface. With a file, you can correct the grooves for maximum connection accuracy.

The next shal is needed to give each blade the shape of the wing, so that the design has earned. The diagram is shown in the drawings below.

To do this, with the help of a pencil, sodium from the middle of each blade in a circle, it will be necessary for this markup with a knife, make slices. What should happen see the photo below.

With the help of a rough file, we process sections of sections, removing all irregularities and snaps.

After coarse processing, we take sandpaper and clean all the edges of the boomeranga until the entire surface is smooth and smooth. It is also necessary to round all the edges.

Next, we take PVA glue or liquid nails, we applied it on both parts of the groove, smear it and glue it with each other. In order for two halves to glue perfectly, it is necessary to hold the place of gluing about the help of clamp or press. Leave to dry up according to the instructions, you can even a little more, that would surely.

After gluing surfaces, it is necessary to remove the glue with sandpaper to remove the glue and finally treat the ready-made boomerang, giving it a beautiful view.

In principle, the boomerang is ready and you can experience it. After tests, the author seemed that the boomerang did not like the fascination, and this affects the accuracy of the reverse flight. To eliminate this problem, the author decided to drag the boomerang. For this, he drilled a hole at the edges of each blade and placed fishing lead loads in these holes.

All irregularities in the places of holes, it is also necessary to clean the sandpaper and pour liquid nails. After the nails are dried, you need to stack an extra sandpaper.

Boomerang is a type of ancient weapon for throwing. Today it is only a toy that many boys dream of. To date, the question of how to make a boomerang at home is becoming increasingly relevant, because everyone knows his ability to return.

Types of boomerangs - Boomerang combat, hunting and entertainment

They acquired their popularity thanks to the return property after throwing back. But there is also a combat type of boomerangs.

Types of boomerangs:

A - combat.
B - "Pil-Pil".
In - "Kylie", which is returned, only when throwing against the direction of the wind,
M - Returning sports - hunting.
D, E - Multiboble returning.

To date, they are made of various materials such as fiberglass, wood, plywood, shockproof plastic and others.

How does the boomerang work and why boomerang returns back?

Boomerang is a kind of throwing weapon, whose history has many thousands of years. Initially, people used to hunt throwing batons, which were naturally not returned as modern boomerang. The first modified the throwing baton of Australian aborigines, who gave it a curved form, which was later called the boomerang.

Properly made and running boomrang always returns back. It does this thanks to physical laws, namely the laws of aerodynamics. Special shape and location of the bumaranga blades creates a lifting power of the flight, like the aircraft. In the Flight, the boomerang is spinning until a certain point. The measures opposed by the effect of the gyroscope does so that at a certain point, the boomerang on the arc changes its direction to the opposite and returns.

In order that the boomerang returned, it must be launched in the vertical plane and in its path are not obstacles. Also always need to make amend to the wind.

How to make a boomerang from the tree do it yourself

Do not know how to make boomerang at home? To make a weapon that returns, you need to accurately comply with the manufacturing technology and drawing compliance. Its drawing is quite simple, and the manufacture of boomeranga occurs in several stages:

If you decide to make a boomerang with your own hands, first of all, it is necessary to draw a boomeranga schema on a dense, but at the same time a thin sheet of cardboard. The drawing needs to be best done with black ink or a well-sharpened simple pencil. In addition, a mesh should be applied on the cardboard, the sides of the square is 5 cm. The size of the sheet must be 0.5 x 0.6 m. After that, overload the outlines of the future boomeranga to it, and from the resulting template they drink a plywood blank thickness 0 , 1 cm.

Drawing diagram of boomeranga

The second stage is the processing of the workpiece you made. It is done by small rules in vice or with a special device. Obtain boomerang from plywood is necessary from the middle to the edges of the blades. Both blades should be symmetrical and have a thickness of 0.6 cm. To facilitate the process of making weapons in the home conditions, you can prepare the counterclabs of the future weapons in advance and apply them to the workpiece to check the correctness of the form.
This weapon must have a perfectly smooth surface. It is for this reason that the next stage of the manufacture of a boomeranga is handling with their own hands. For this applies sandpaper. After grinding, the blank is ground, and after it is painted or vague.

If you have the opportunity, it is best to make a boomerang from a tree. For this, as a rule, severe bows and roots are taken. It should be noted that the tree should be quite well dried, dense and heavy. To do this, you can use such woods: beech, oak, lime or birch. The principle of manufacturing a wooden boomeranga with their own hands is no different from plywood. It should be remembered that the wood is spoiled faster than plywood, so it needs to be carefully covered with paint and varnish material.

Conducting boomerang - how to make a boomerang from plywood or wood

Material that is suitable for making this is any heavy tree.

Two-blade option boomeranga

In accordance with the schematic pattern, blades are made. After that, the grooves are cut into them. After that, the "wings" glued or connected with screws. In this case, it is necessary to monitor the balancing. Because with the slightest violation, you can make a boomerang that returns.

Three-bladed boomerang

This option has a greater range and flight time. In the case when you have no experience in throwing this weapon, the length of the blades should not exceed 0.25-0.3 m.

How to make a boomerang from cardboard (paper)

If you have a child who loves unusual entertainment, then a paper boomerang is suitable for it, made with their own hands. First of all, this is an exotic, you can even say ethnic craft, even though paper is only an alternative to wood. In addition, to launch a boomerang that you made yourself, even if you can even take your child an unforgettable pleasure.

If there are boomranga drawings with sizes, then make it easy. Paper boomers are three-, four - and five-eyed. In accordance with a schematic pattern, in order to make a boomerang of any design with their own hands it is necessary to cut the right amount of blades. After that, the finished items are required to be copped with flashes, with each next element must be superimposed from the same side.

Run can be carried out both in the open air, in the park, or in the courtyard and indoors, that is, in the office or apartment.

Differences between two-, three - and four-odd boomerangs:

Two-blade - You can leave much longer, but they take off is not very high.
Three-blade - can take off above, but they have a low sighting distance.
Four-blade - It takes off high due to the fact that they have excellent lifting force, but as long as they appear on the height reach, boomerangs are capable of making several laps. But it is not always convenient.

Remember: If you change the profile and drawing of the blades, then the main specifications, such as accuracy and range of flight. If at home conditions Boomerang was made according to technology, he does not differ anything from the specialist.

How to properly run boomerang and safety

It is necessary to throw it from behind the back, in the direction of ahead and a little up, at an angle of about 45 degrees to the horizon. He will make a circle in the form of petal and return. But in order for you to work out, you need to train.

But it should be remembered that this is not just a toy. He earlier with his help, people minted meal, and if it belongs to the boomerangu, it is negotiable, then you can get a serious injury. So it is necessary to train on startup in an open area, as far as possible from people and buildings, but at the same time constantly follow him.

Remember: The use of boomeranga made of plywood or wood without compliance with safety regulations may entail criminal punishment.

Today we will talk about how to make a boomerang yourself with your own hands at home from girlfriend. We also consider the methods and technologies for the manufacture of boomerangs different designs With visual drawings and illustrations

Wings of boomeranga - when they rotate in the air - are able to create sufficient lifting force. This is due to the fact that the wings have a special aerodynamic form due to their corner of the tilt and the bevelled lower part.

But the phenomenal in the flight of the boomeranga is the process known as the precession of the gyroscope - the effect in which physical body changes the direction of his movement - the key point in which the return movement of the boomeranga is provided to a person who bothered it

It is worth noting that the reception with the return of combat boomeranga was used by warriors and hunters exclusively in training purposes, well, or as a method of some intimidation

When the boomerang rotates in flight, in fact, one of its wing is moving a little faster relative to the air flow. And since this wing has a higher speed, then, accordingly, the lifting force under it acts stronger. The result of this is an unbalanced effort (the phenomenon of the precession), which gradually and returns the boomerang "

In other words: the difference in lifting power between the two sides of the boomeranga produces a sequential torque that makes the reverse turn. So boomerang soaring in the air so long and returns back, describing the arc

How boomerang works - it takes in hand in a certain way and with a force, it is rolled under some angle perpendicularly up, and the stronger the twisting, the further, it will be more powerful to throw and return to the starting point. So, you throw up, throw a boomerang, but in the last moment you do not let go to the end of the brush, and sharply, as it were, delay it and pull out, as they say, "Shake a thermometer".
With a sufficiently powerful throw, at a distance of a hundred meters you can freely raise the rear-year rabbit or knock the partridge on the lonely palm. They didn't get - not scary, the boomerang arrive back, only time to bounce (humor) well, and if seriously, we will not disassemble the processes leading a boomerang flight to its accuracy of getting and returning to the point of the throw in the absence of such. Our goal is to properly produce this terrible weapon of the past.

For the manufacture of boomeranga, solid wood varieties are needed, such as oak, birch, beech, linden, etc. To give greater aerodynamicity and strength, you can enclose the boomerang fiberglass with epoxy resin, then polish and polish. Profile need to make a slightly plane, but do not overdo it, is enough 8-12%

It will take to make a boomerang with your own hands:

Cardboard sheet;
Plywood or tree;
Varnish or paint;
Lobzik;
Plane;
Sandpaper.

First of all, you need to draw the selected boomeranga model exactly in a natural value on a dense and thin cardboard sheet. It is recommended to select the size of the leaf of 50x60 cm. After that, it is necessary to transfer the grid of the square to the cardboard, which is 50 mm. From the received template, drink a blank from plywood. Its thickness is 10 mm.

Now you need to handle the workpiece. This should be done by a small-sized batch in vice or with the help of a device that is shown in the image (g). Boomerang need to oversight, starting with the middle, moving towards the edges of the blades. Their end must result in a thickness of 6 mm. The blades must be absolutely the same in shape. To simplify the task, you can make counterbasks blades from plywood and apply them to check the correctness of the forms.

This is how relatively easy it is possible for an hour - two make a boomerang with your own hands. If it is possible, it is recommended to make a boomerang of wood. For this, as a rule, dried bits and roots are used. It is important that the tree is dense, heavy and well dried. For the manufacture of boomerang suitable: oak, birch, beech, linden. The manufacturing process is exactly the same as in the case of plywood. But it should be remembered that the tree will deter much faster plywood, so it needs to be covered with varnish or paint especially carefully.

If you have fulfilled all the rules when creating a boomeranga, it will have excellent flight qualities and a beautiful appearance. How to make a boomerang with your own hands we figured out, now you need to deal with how it is correct to run.

To run the boomerang for the first time, despite all the seeming simplicity, it is quite dangerous due to unpredictability, so it will take some caution and attention. Boomerang can be completely in someone to get, so you should not begin experiments in crowded places. The optimal place for training dexterity and accuracy - meadow or glade with a radius of 40-60 meters (the more, the better). A soccer field or a wasteland can become such a melayer.

.
Boomerang has two main surfaces. The convex facial side, which, as a rule, caused a drawing, creates its effects when rotating. The back side, in most cases, is flat, it can also see the drawing on it, but with proper throwing, usually, you can only see the front side.
Boomerang is customary to keep like this: the thumb always lies on the front side. Keep boomerang correctly - means keeping his face and see a good picture.
Boomerang can be kept and the wing back and the wing forward. It is not fundamentally and in any case correctly - as you will be more convenient.

Many newcomers on the subconscious level launch boomerang, tilting it as a sickle, which the grass is cut, almost in parallel to the Earth. It is absolutely wrong. In the boomeranga, the aerodynamics is designed so that it is correct to throw it - it means to throw almost perpendicular to the horizon, at the same time the slope to the horizon line should be to the right of the imaginary perpendicular. Release boomerang during the throw should be at an angle of no more than 45 ° to the horizon line.

Boomerang should throw sharply and strongly. When you start the boomeranga, it is necessary to take into account the fact that the projecture requires the force not only for flight from the thrower, but also for the return path and the loop behind the thrower. Therefore, throwing should be extremely strong and sharp, especially if for training you use a real wooden boomerang, and not a toy plastic copy. As a rule, the first throws are timid and careful, especially if a woman or child throws. But you should not be afraid! Any high-quality boomerang is designed for a powerful throw, because if you throw it weakly, it will lead to a rapid fall somewhere along the trajectory, which is not very good for him.

Throw boomerang is necessary right in front of yourself, looking and focusing on the horizon line. It is worthwhile to throw a boomerang up - it is better to throw it straight forward, because the design of the projectile is that it will independently gain the required height.
During the first throws, there may be a situation that you, as you may seem, throw a boomerang sharply and strongly, but it flies all the same smoothly, without spinning as required. In this case, you need to master some spin skills. If you throw the projectile correctly, it will be twisted as quickly as a propeller - the drawing is alive in a solid circle, it will not be visible to the blades. To ensure maximum twist, competent capture is extremely important. In addition, the boomerang should not be too much to drag in the fist.

How to launch boomerang we figured out, but the wind should be taken into account. The wind is not a major factor that affects the flight path not only boomeranga, but also all air shells and devices. Its influence should be taken into account when throwing no less than the force of the throw and the correct grip. If the wind is very strong, a sharply changing direction and power (intermittent), the training is better to postpone and work out once again the theoretical part.

Training is better to start in calm windless weather or with a slight, non-changing wind direction. If you make throws in the wind, then the throw is recommended to direct the wind towards the wind a little right of its movement. With such a throw, the wind will help the boomerangu back to the thrower. Among other things, the wind has a strong impact on the accuracy of the return of the projectile, because the behavior of any aircraft depends on the existing air flows. With the wind can be made friends, but it comes only with experience and after numerous workouts. From the first time, comprehend this art is simply impossible.

By the way, all the flight properties of the future boomeranga largely depend on the last operation, thoroughness of its implementation and accuracy, so it is better not to regret the time and with failure to take up the work again. If the boomeranga profiling turned out to be "five", taken for grinding and varnishing wood. Finish finish-bright oil or nitroemal. If there is no significant deviations from the form from the specified in the drawings, additional debugging will not be required.

Immediately it should be noted that the battle projectile was originally created by far ancestors, called boomerang, not necessarily returned. Special types of boomerangs did not expect a reverse trajectory at all and were called because they had the main classification features - rotation in flight around the transverse axis and the elongation of the flight range due to aerodynamic (planning) properties. The returnable boomerangs served mainly for hunting for small animals and birds.

For sports and entertainment purposes, much easier "shells" are currently used. They are practically safe, although during their launches it is necessary to observe some precautions. The best material for the manufacture of sports boomranga must be recognized as a olhovy five-layer phanener with a thickness of 6 mm (with smaller sizes that differ significantly from those indicated in our drawings, it is necessary to find a more subtle material, respectively).
After processing the sheet blank along the contour, it is carefully profiled. By the way, all the flight properties of the future boomeranga largely depend on the last operation, thoroughness of its implementation and accuracy, so it is better not to regret the time and with failure to take up the work again. If the boomeranga profiling turned out to be "five", taken for grinding and varnishing wood. Finish finish-bright oil or nitroemal. If there is no significant deviations from the form from the specified in the drawings, additional debugging will not be required.
When starting the boomeranga, use practical advice Our publication reflected in the drawings. In conclusion - about possible schemes. Search interesting decisions Not limited to the choice of shape and sizes. To a large extent, flight data depend on the material of the boomeranga. For example, the Multibore chamomile scheme in the complex using foam can lead to the creation of ... room option, the range of which does not exceed three meters.

Take a sheet of tight paper and apply a grid of a square of a square of 50 mm on it. The side of the boomeranga facing the reader is convex. Carefully transfer the contours of the model from the picture and cut out. You got a pattern. Shoulder symmetry Check by rebuilding it along the OA line. The shoulder contours must completely match. The best and perhaps the most affordable Material For the manufacture of boomeranga - plywood. Rubber glue Stick the template on the plywood sheet so that the outer layers of the plywood are perpendicular to the OA axis. Lobzik Cut the side of the shoulders of the boomeranga.

All subsequent processing is performed only on the one hand. The other party should stay flat. With the help of a flat filetry and calipers, achieve a smooth reduction in the thickness of the middle to the ends. Having done this, make up profiling. This is perhaps the most responsible part of the work. Cut from tin or fine plywood counterclands for each section specified in the figure. Profiling is performed using semicircular and flat files, and then clean the entire surface with the skin. All sharp edges round. .

The surface of each shoulder is carefully treated, the flight quality boomeranga will depend on it. Check the counterclamps of the obtained cross sections to the lumen. It is also very important to thoroughly balance the boomerang. To do this, hang it on the thread,
attaching it on the cross section of OA: none of the shoulders should outweigh. If one shoulder is harder than the other, it is necessary to establish the cause. This may be caused by either improper processing, or inhomogeneity of plywood. In the first case, the equilibrium is achieved by a heavier shoulder, in the second - by sealing into the edges of the light shoulder of a small lead rivet. Place of sealing must be carefully composed with the plane of the shoulder.

We warn you: Flying boomerang is a danger not only for the thrown, but also for others. It is best to run it on great. Open platform or lawn, removing viewers for a greater distance. So that the model is better visible, apply bright stripes on the shoulders different flowers. It can be given the necessary water resistance to it, covering the shoulder surface with colorless varnish. Ready boomerang color bright oil or enamel paint several times.

How to make three and four paddle boomerangs do it yourself

Material of manufacturing - medium and heavy varieties of wood, oak, linden, birch, beech, etc. Phaneru actually for this scheme is difficult and not advisable. In the middle of two blades, the grooves are cut on different sides, after which they glue the PVA liner or carpentry, in general, any sufficiently durable glue for the tree. For greater strength, you can connect small screws.

Usually offered to make mainly G-shaped boomerangs. In my experience, r - the figurative boomers are significantly inferior + (cruciform) in absolutely all characteristics. They do not fly away so far. It is necessary to throw them under a strictly defined angle with one definite force, whatever he returned for sure. The time of staying in the air is one and a half times less.

Flight of the boomeranga is a stunning spectacle. With a strong throw, in flight it describes a large loop, flying away far - forward and returns back. If you throw a stone with exactly such force, it will not fly and a third of how much a good boomerang flies. Boomerang can be taken with you on an active holiday. You will get a lot of interest from such a holiday. With him you can do as with sports shell In physical education and sports, developing muscles of the hands, coordination of movements, etc.

Launch boomerang, especially sports, I recommend only on large open areas, into few windy weather, in the absence of people's proximity. If there are buildings nearby, there may be a glass or shell flying somewhere on the roof. If people walk nearby, they can get on the kettle. The above are the schemes of amateur boomerangs. Sports are distinguished by large sizes and mass.

How to make the perfect boomerang with your own hands:

The blades are wider, tech as it increases the number of Reinwaldos.

The elongation of the blades do more, it will reduce the inductive resistance.

Mass concentrate at the ends of the blades, it increases the rotation energy stock

Reduce the number of blades, it will reduce the harmful interaction of the blades

If you do all this, then you will get up to 20% of the gains of flight data.

A diagram of a two-bladed direct boomranga, similar to a twist of a helicopter, is obtained. But the two-bladed will be absolutely not stable, and the application of the stabilization scheme is not justified. Three-blade scheme meets all requirements. If you give reverse speeds to the blades, then the inductive resistance at large angles of attack will decrease, this happens at the time of changing the flight path. And the energy of rotation on the cortic angles of attack will not be lost.

There are many ways to create a wooden boomerang independently capable of returning back.

So that it turns out to be truly "workers", it is necessary to devote a sufficient amount of time to design and develop a drawing, so it's better not to hope for imminent results.

This is a time-consuming and time procedure that can give a large relaxic and moral pleasure, but also in need of excerpt, perseverance, perseverance and accuracy.

How to independently create a drawing of a wooden boomeranga

Designing the boomeranga can be calmly considered to be truly engineering, and its first stage is the classical creation of a correct and accurate drawing.

The most reasonable solution will be the use of a finished and proven project.

Such drawings are usually already created with all the nuances and do not require mathematical calculations. You just need to fit the desired scale.

How to choose and prepare material

Make boomerang is most correct not from any boards or log found in the forest, but from solid wood, the most common and affordable representatives of which are Lipa, Birch and Oak.

It is best for these purposes curved by approximately one hundred degrees of the board - exactly of them will make it easier to make the required subject.

The most optimal option will search required Material In the near forest. It is better to take an ax or a saw blade with you.

If there is a desire to create several boomerangs at once, it is optimally chosen by a branch with a diameter of about ten cm. But if you plan to invent only one product, you can skip this recommendation.

If it was not possible to find dry snag, then it will be necessary a large number of time for drying. The whole procedure will take a period of time per year.

Neglect this rule is impossible. Wet wood will not succumb to the necessary manipulations during the processing, which can be pretty nerves.

To accelerate the drying process of fresh wood, it is required to get rid of the crust and anoint the ends of the material.

This will help heine a piece evenly and avoid the appearance of cracks. No matter how much I did not want to start making a boomerang rather, to dry the wood under the right sunny rays or the battery is prohibited.

The most qualitatively tree will only dry in 12 months, subject to the place in a ventilated place.

How to create a boomerang from the tree yourself

If there is a dry piece of wood, you can begin to design the desired boomerang.

This requires strictly and carefully follow the following plan:

Spile the peripheral parts with a joinery tool for planing of a tree
(Preferably) or circular saw, you need to make a bar flat and uniform in width.
Snain the bar of visets and, using a manual sawmill, saw. Must happen several
Squares width in one or two centimeters.
Note the border according to the selected drawing. In order for the boomeranga's wings to acquire the necessary look, apply the drawing on the bar and fidgeted unnecessary areas to be well noticeable, to where you need to negotiate. If you have difficulty drawings, you can resort to the help of the printer and glue it to the tree.
Using a jigsaw or grinding machine, get rid of the extra parts.
The next step is polishing - using a grinding machine or sandpaper, it is required to polish the edges of the workpiece. It is important to remember that the product is polished only from the front side, and the other party should remain smooth, not counting the edges. This is the chispping stage: it is necessary to work without hurrying and very carefully, in the opposite case you can spoil the entire work done.
Next, it is necessary to polish the product with shallow emery paper so as to completely get rid of all the nuances of the work done and give it the necessary smoothness.
To boomerang, do not conquer, did not get dirty and did not deteriorate, it is required to periodically apply lacquer. If you want, you can apply a pattern or picture with paint.

Upon completion of all the above stages, it is necessary to wait until the varnish and paint will be fastened in a well-ventilated place.

A safe place for testing is an empty stadium in a deserted clock or any other open space with good visibility.
