Making a boomerang yourself at home is not difficult. In this article we will tell you about making several types of these flying objects.

Do you know that not all boomerangs return to their owner after being thrown? When hunting large animals such as kangaroos, the Australian Aborigines used non-returning boomerangs. They threw such a boomerang almost horizontally. And it itself was less curved than its modern counterpart and reached a length of up to 1 meter.
Today, boomerangs are not used for practical purposes. It is used to develop manual dexterity or just for fun. Overall this device is not tricky. Great for learning the basics of aerodynamics.

Classic L-shaped boomerang

Material for production: thin plywood.

First, let's prepare a template. Take thick paper and mark it with a square grid with a pitch of 50 mm. In the diagram, the convex side faces the reader. Transfer the contours of the boomerang from the diagram onto the prepared sheet of paper and cut it out. To check the symmetry of the resulting template, bend it along the OA axis. Check that both sides of the boomerang match.

Now glue the template onto the plywood sheet. In this case, the outer layers of plywood must remain perpendicular to the axis OA. Cut the boomerang along the contour with a jigsaw. Please note that finishing should only be done on the side shown in the diagram. Leave it on the bottom flat surface. To ensure that the thickness of the boomerang smoothly transitions from the middle to the edge, use a flat file.

For each section considered in the figure, make a counter-template from tin or thin plywood. Next, use the same flat file (or semicircular) to profile and sand the surface. The edges must be carefully rounded. During the entire procedure, do not forget to constantly compare the profiles of the boomerang sections with the templates in the light.

All that remains is to balance the boomerang. To do this, you need to attach a thread to it along the OA axis and then hang the resulting structure. None of the “wings” of the boomerang should outweigh. If such a situation does occur, correct the balance of the model by attaching a small lead rivet to the “wing” that is lighter.
Everything is ready. Now you can start decorating the boomerang and then coating it with varnish.

Cross-shaped boomerang

Material for production: linden, oak, birch or other heavy wood.

Two-bladed version

According to the diagram below, make boomerang blades. Cut grooves in them. Then glue the “wings” or connect them with screws, making sure that they are balanced.

Three-bladed version

The range and flight time of such a boomerang increase from 3 to 8 percent.
If you do not have experience with a boomerang, then it is advisable that the length of the blades in both variants of the scheme does not exceed 25-30 cm.

Safe boomerang

Material: paper.
This option is absolutely safe for others. Making a boomerang from paper is extremely simple. As a result, you will get a boomerang that duplicates the principle of operation of the wooden prototype. Following the diagram, cut out a blank from paper.

Bend the edges of the blades towards you. If you are left-handed, use the opposite direction of the bend.

Well, you have achieved the desired result, as you can see, making a boomerang at home turns out to be very simple, the main thing is to really want it.

Safety precautions

Making a boomerang also entails basic safety rules for its use. It is recommended to use a boomerang on large open areas in calm weather. There should be no people nearby. If you notice someone, you need to warn him about your actions.

Attention! Using a boomerang without following safety precautions may result in criminal penalties. The information in this article is for peaceful purposes only. Any person who uses the obtained data for criminal purposes bears full responsibility for his actions.

And finally, here’s a video on how to make a boomerang out of wood:

In ancient times, the boomerang was used as a formidable and powerful weapon. Nowadays it is used more for decorative and sporting purposes. Making a boomerang with your own hands is not very difficult if you follow the instructions. But in order for it to fly exactly as intended and return along the correct trajectory, attention should be paid to its manufacture.

What you need to know to make a boomerang

A boomerang is best made from hard rocks tree. These species include birch, oak, linden, beech, etc. But a boomerang can also be made from plywood.

To make the boomerang more durable and aerodynamic, it can be covered with fiberglass and epoxy resin.

Making a boomerang

As a rule, bent roots and branches are used for boomerangs. The wood must be well dried, heavy and dense.

• take wood or plywood 10 mm thick;
• draw a template;
• We cut out the workpiece from the resulting template using a small plane. We pre-clamp the workpiece in a vice;
• We sharpen the boomerang, starting from the middle and moving towards the edges. The ends of the boomerang should ultimately be 6 mm thick. Its blades must be absolutely identical in shape;
• polish the boomerang sandpaper;
• cover with primer and let it dry;
• then cover it with paint or varnish.

It is better to take bright paint so that the boomerang can be seen from afar. If you decide to varnish it, then it is better to use parquet varnish; it will help preserve the aesthetic structure of the boomerang.

How to make a boomerang with your own hands for fun and relaxation.

A good material for its manufacture is eight-mm alder plywood. We will need a piece measuring 8 x 450 x 450 (mm).

Let's consider the sequence of stages of work performed:

Preparing the template for cutting
profile production
painting and sanding

PREPARING A TEMPLATE FOR CUTTING

We will need a compass, a pencil and a conveyor. We will denote the coordinates of points by radius and angle.
Let's look at the picture

Let's draw bottom part boomerang. Upper part- This mirror image bottom part. We will draw section lines at the required angles. Let's draw circles of the indicated radii. The point of intersection of the circle with the section line is the point at which the model outline is constructed.

From the construction of the drawing, eight sections were obtained:

central section

seven lower sections

top seven

If from the radius value, draw the section length along its line to the center ( L), then we get the second construction point on the section line.

Table of values ​​of geometric dimensions of sections in millimeters:

2 – L = 80; l = 23 ; h = 7.80
3 – L = 74; l = 22 ; h = 7.80
4 – L = 68; l = 20 ; h = 7.20
5 – L = 64 ; l = 19 ; h = 6.80
6 – L = 62; l = 18 ; h = 6.50
7 – L = 59 ; l = 17 ; h = 6.25
8 – L = 46; l = 16 ; h = 6.00

The constructed circuit will be cut out with an electric or with a hand jigsaw, then align the end faces.

PROFILE MANUFACTURE

1. We carry out rough processing using manual grinder, a set of rasps, coarse sandpaper. On the cut template we draw a line for the material selection boundary.

We place the contour points along the section lines, at a distance ( l) outside the edge of the template

2. Removing excess material:

- along the wing width

- along the length of the wing

3. We will do similar work with the second wing, only we place the contour points along the section lines, at a distance ( l) With inside template edges.

4. Fine processing is carried out using fine-grained sandpaper stretched onto a flat plane of the block. When processing a surface, you must strive to perfect shape sections along the entire length of the wing.

5. At the final stage, we scrape the surface using a small piece of glass.

From AlexGyver, a four-blade boomerang made from improvised materials. Almost anyone can make such a boomerang; the materials used in homemade products are available to everyone. This boomerang starts working immediately after assembly if you follow all the recommendations and instructions, and the small improvements that will be discussed will help improve its characteristics.

So, to make a four-bladed boomerang, the author used the following materials:

1. Two slats, length 30 cm, width 4 cm, thickness about 7 mm.
2. PVA glue for wood or liquid nails
3. Auxiliary tools - file, hacksaw, knife and sandpaper

Making a boomerang

First you need to prepare the material; for this you need to cut the slats to the desired size and sand them well with sandpaper. The author recommends not using wood that is too dry, since the heavier it is, the better the boomerang will fly.

After preparing the material, you need to mark the workpieces. They will be fastened to each other crosswise, and they must be fixed in one plane; to do this, it is necessary to make grooves in the center of the slats so that one fits into the other. We mark the slats as shown in the photo below, the dimensions are arbitrary, the marking from the end should be equal to half the thickness of the slats.

The next step is to make cuts using a hacksaw for metal in the marking places, the cut should be made on front side slats to the middle, this needs to be done with two blanks.

After all the manipulations, both planks should fit into each other as perfectly as possible, forming a solid and smooth surface. Using a file, you can adjust the grooves for maximum connection accuracy.

The next step is to give each blade the shape of a wing in order for the design to work. The circuit is shown in the figures below.

To do this, use a pencil to shade from the middle of each blade in a circle; along this marking you will need to use a knife to make oblique cuts. See the photo below for what you should get.

Using a coarse file, we process the cut areas, removing all irregularities and dimples.

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

Next, take PVA glue or liquid nails, apply it to both parts of the groove, spread it and glue it together. In order for the two halves to stick together perfectly, you need to clamp the gluing area using a clamp or a press. Leave it to dry according to the instructions, maybe even a little longer to be sure.

After gluing the surfaces, be sure to remove the exposed glue with sandpaper and finally process the finished boomerang, giving it a beautiful look.

In principle, the boomerang is already ready and you can test it. After tests, it seemed to the author that the boomerang did not wax enough, and this affected the accuracy of the return flight. To eliminate this problem, the author decided to make the boomerang heavier. To do this, he drilled a hole along the edge of each blade and placed fishing lead weights into these holes.

All uneven areas at the holes must also be cleaned with sandpaper and filled liquid nails. After the nails are dry, you need to sand off the excess with sandpaper.

Boomerangs are a type of throwing weapon made from wood that was used in ancient times. However, the time when they were dangerous and serious weapons has long passed. Today, this throwing weapon is a simple, ordinary toy that both children and adults will be delighted with.

It is worth noting that you can make a boomerang yourself, at home. To do this you need to stock up on everything necessary materials and follow all instructions for making it. Main feature The boomerang is that when thrown correctly, it returns back to the person who launched it. However, it should be noted that there are special, combat models that do not return to their owner after being thrown.

Important! Despite the fact that the boomerang is a simple toy for entertainment, it can still cause harm to human health if used incorrectly. Therefore, before launching boomerangs, it is recommended to familiarize yourself with the relevant safety precautions and familiarize yourself with the rules for launching it.

Probably, most people have a completely logical question: how can you make a boomerang, what is necessary for this? In answer to this, it should be noted that making a boomerang out of wood that returns is not so difficult. After all, as a rule, when making it yourself, dense, durable wood is used.

As an analogue, when making it yourself, at home, instead of wood, you can use multi-layer plywood as the starting material. The thickness of the plywood should be at least 8 cm. Answering the question: how to make a boomerang from plywood, it is worth noting that in this case, during its manufacture, it is preferable to use imported waterproof plywood.

This is due to the fact that imported plywood, unlike similar products domestic manufacturer, will not delaminate during use. In addition, it is shock-resistant, so a boomerang made from it will not fall apart in the event of a collision, for example, with the first tree that comes along.

Note! For making boomerangs small size can be used as a starting material, ordinary cutting board, which is in every person’s kitchen. This board is made from seasoned, dry wood and is excellent for further processing. This is especially important when the material needs to be given the desired shape while respecting all angles.

There are many varieties of boomerang. They are:

1. Combat.
2. Sports - hunting.
3. Multi-lobed.
4. Peel - drink.
5. Kylie.

However, it is worth noting that not all boomerangs can return to their owner after launch. For example, combat models do not have this ability. Before you start making a boomerang with your own hands, you first need to get a drawing of it. Today this is not such a big problem, because a drawing of a boomerang of almost any type can be done without special effort get it on the Internet.

The product drawing must be printed or drawn on a sheet of paper and special coordination grids applied to it. The size of the mesh cells should be 5x5cm. Thanks to the use of such a mesh, it is possible to more accurately model and scale the workpiece. After drawing the drawing, you can proceed directly to the manufacture of the product itself.

Required materials and tools

For self-made To make a boomerang you will need a small amount of materials and tools. During the artisanal, independent production of this product you will need:

• a sheet of plywood or well-dried wood;
• one sheet of cardboard;
• varnish (as an alternative, it is fashionable to use paint);
• jigsaw (you can use a jigsaw if you have one).

Also during its manufacture you will need a plane for the initial processing of wood and sandpaper of different grain sizes. As an alternative to PVA glue, it is best to use epoxy. To apply paint or varnish you will need a brush. Also, during its manufacture you may need a knife and a hacksaw.

The manufacturing process does not take much time and effort. On initial stage production, you need to make a sketch of the product, while observing its proportions natural size, as well as forms. To do this, the drawing must be transferred to a sheet of cardboard. The cardboard should be dense and of small thickness.

Making your own boomerang out of wood, which returns at home on your own, is quite simple task, which will not take much time and will not cost much effort. Everything you need for self-production of this product is directly its drawing (diagram) and that’s all necessary tools, as well as consumables.

It is worth noting that when choosing a drawing, you need to take into account the fact that not all boomerangs are designed to return back to the original point of their launch. For example, the fighting or heavy models that were used by the Australian Aborigines for hunting do not return back to the person who launched them. Some homemade models made from wood with your own hands can only return if they were launched against the direction of the wind.

Cutting boomerang material

Once the drawing of the product has been found and its dimensions have been established, you can begin making the boomerang. For example, it can be made from 3 ordinary pieces wooden slats. The lath can be made of pine or birch. At the initial stage of manufacturing, it is necessary to make all measurements and cutting drawings on the slats, as well as their subsequent connection.

Then, along the previously drawn lines, you need to make cuts using a hacksaw, ½ of the thickness of the slats. It should be noted that the cuts must be without distortions, on both sides, both above and below the slats.

At the cut points, using a knife, you need to carefully, being careful, break out parts of the wood. As a result, you should get a groove with a depth of less than ½ of the thickness of the rail itself. The broken areas must be processed using a file. The surface of the wood must be perfectly flat.

Output of wing profiles

After the materials and individual elements the products have been prepared, you can start assembling it. Then you need to use a knife to give the boomerang blades an aviation wing profile. It is very important not to confuse the sides of the product.

Bending boomerang blades

During the manufacturing process, the blades of the product need to be given a slight bend. It should be noted that it should be on the convex side of the blade. It is worth noting that the bend affects the speed at which the boomerang returns to the original point from which it was launched. Simply put, the greater the bend, the faster it will return to the owner after launch.

To bend the blades, place them in a container of boiling water and wait a few minutes until the wood begins to soak and become flexible and soft. The blades can then be bent. It should be noted that the bend should be small. To give the blades the necessary bend, you can use cylindrical objects.

Painting and varnishing

Before painting, the boomerang must be assembled and its surface carefully treated with sandpaper so that there are no burrs or irregularities on it. It can be varnished or a special impregnation for wood that has no color can be used. It can also be painted using ordinary paint in any color. To do this you need to use a very ordinary brush.

To ensure that the product dries without the layer of applied paint being smeared on its surface, you need to use a special stand. An ordinary sheet of plywood with three nails hammered into it can serve as such a stand. It is necessary to carefully place the product on these nails so that the paint on it dries and does not smear.

Video on how to make a boomerang from wood

Wood is the most popular material that is most often used in the manufacture of boomerangs. This is due to the fact that wood is light, durable and at the same time available material, which you can easily find in your home or buy at the market or in hardware store. There are many different models of boomerangs made from wood. To get acquainted with them, as well as with the main nuances of their manufacture, circuit drawings, dimensions and pictures, you can watch a video posted on the Internet.
