A basic DIY kite consists of three slats glued to a sheet of thick material. A tail with a small weight is attached to the end, serving as a rudder. It is important to place the center of gravity in the middle of the body, then the structure can rise into the air. The lighter the kite load, the higher the takeoff will occur. It is necessary to take into account the fact that as the lift of the kite increases, the thrust from the ground increases. Basic structure is exposed to air pressure, so the material for manufacturing must be strong and rigid.

What is a kite

Initially such aircrafts made in China in the shape of a dragon - not a single traditional ceremony was complete without this symbol in the sky. And although the manufacture of structures has long gone beyond the borders of China, the name has stuck. Various models of flying devices can be with a base, frameless, flat or multi-plane design. The finished apparatus is held in place by a long rope called a handrail. The aerodynamic shape promotes stability, and the strong thread helps keep the kite at the desired airflow angle.

Design

The design of a simple kite, from a flying frame with a tensioned covering, can be assembled at home. It won't gain much height, but it will be a good start for gaining initial construction skills. There is a single principle at work here, based on aerodynamic, physical properties items. Slings are attached to the corners of the body and combined into a bridle for sustainable management. Each model is decorated and stabilized by a tail. Maneuverability will be improved by additional cargo or multiple tails.

Operating principle

The main condition for a high launch is wind speed (3-4 m/s). It is recommended to launch the finished model in an open area where there are no trees or wires. A well-made structure will be lifted by the air masses themselves. You need to stand against the wind, releasing the rope 10-20 meters. In light winds, you can run to catch the moment when to send the flying device into the air. It is better to cope with this task together. The smoothness of the flight depends on how correctly the tail and the length of the lines are adjusted to the size of the structure.

Species

There is a choice for your choice a large number of models: flat, volumetric, curved, frameless, triangular or consisting of several links. The latter differ from a flat kite in their high structural stability. Multi-cell form, with a large number of individual links, connected in the form of polyhedra. A group of interconnected flying devices looks impressive in the sky. The width of such a product is suitable for attaching a small camera to it for aerial photography from a height.

How to make a kite with your own hands

To make a flying kite at home, you need to choose a model that determines the shape of the frame and the surface material. Determine the number of support rails that support the canvas in tension . Sheets of paper, fabric, plastic bags, and cardboard are used as canvas. The slings can be secured in one or two places on the base. Good aerodynamic force can be imparted to both uncontrolled (single-line) and controlled (multi-line) models. The thread winding spool will eliminate tangling during startup.

From paper

You can make a kite out of paper as follows:

1. Fold a square out of thick paper.
2. Label the axis of symmetry.
3. Fold the sides in half.
4. Fold the corners to form an accordion.
5. Pass a long thread through the center of the accordion.
6. Attach the adjustment rail.
7. Connect a bundle of threads prepared in advance.
8. Decorate the free end of the ponytail with bows or rags.
9. Pull the tail through the hole and secure it securely with a rope.

From fabric

Develop an original pattern to make a flying kite toy from wire using fabric:

1. Wrap a piece of flexible wire with threads and secure them at the ends.
2. Shape the wire into the desired shape.
3. Trace a piece of fabric along the contour of the frame, leaving an allowance of one and a half centimeters.
4. Glue the fabric to the wire blank.
5. Decorate the surface.
6. Tie the rope in several places.
7. Bring the ends of the ropes to one point, retreating 30 centimeters from the kite, and secure them together.
8. Tie the rope.

Made from polyethylene

DIY kite made of polyethylene:

1. Prepare two planks, one being twice as long as the other.
2. Fold them, moving away from the top of the long bar.
3. Secure the connection point with tape.
4. Wrap the strips with tape and make small cuts.
5. Pull a strong thread through the cuts and secure it.
6. Trace the outline of the finished frame on polyethylene, adding one centimeter.
7. Cut out and tape the edges.
8. Tie a 30 cm long thread onto a short stick.
9. Snap on top part a long stick, a piece of fishing line.
10. Connect all three ends of the fishing line to each other and secure the thread of the lower corners, by which you will hold the kite, with tape.
11. Decorate the product with ribbons.

Dragon Kite

Design big size, with contours resembling a dragon, is performed as follows:

1. Select materials for the frame and covering.
2. Make a support base for the desired shape of the flying dragon.
3. Secure the connected structures with thin rope.
4. Make a drawing of the model on paper, use it as a template.
5. Cut out the outline of the kite for the airfoil.
6. Decorate the surface with homemade designs or stickers.
7. Attach the outer trim to the frame.
8. Attach the slings, tie the rail.

Box kite

The box kite is a multi-plane kite. It's done like this:

1. Make 4 long wooden slats and 6 half-short wooden slats.
2. Secure the short ones crosswise with a self-tapping screw.
3. Attach the long slats to the small ones in the center and ends.
4. Tie the larger sides at the corners with wire or rope in a crisscross pattern.
5. Wind the rope around the slats, secure it with tape in shape rectangular parallelepiped frame.
6. Attach the plastic strips to the slats, making a complete rotation around the object.
7. Stretch a rope over the cellophane covering around the perimeter of the square and glue it tightly to the surface.
8. Make loops of wire for tying the line.

Diamond Kite

You can assemble a kite with your own hands so that the design has improved aerodynamic characteristics. The description will help you:

1. Make 6 long wooden slats and 4 slats half as long.
2. Make small crosses.
3. Cover the sides with wire and secure.
4. Attach long slats to the sides of the crosspieces.
5. Coat the wooden slats with drying oil.
6. Tape the frame around each cross piece.
7. Align the frame perpendicular to the position of the slats in the crosses.
8. Cover the body of the kite with two layers of tape, being careful not to damage the shape.
9. Tie a strong thread to each rail and secure with a strip of tape.
10. Attach the fishing line to the wide side of the diamond at both ends of the batten.

Good afternoon dear friends, today we will meet you and see the amazing works of a talented artist Brian Jewett, these are cacti from a hose. Unfortunately the author did not detailed master class of his work, he told us how to do it and what we need for this... Thanks to this idea, wonderful and beautiful cacti can now grow in our garden and decorate our site. To make cacti we need very little time, clamps and a hose. You can buy clamps at any hardware store, I think you won’t have any problems with this. We also need a hose, preferably Green colour. If not, you can paint it the color you want. You can also make such cacti from a soft corrugated tube. There is no need to run out and buy materials, look at your dacha or barn, I think you will definitely find old unnecessary hoses that can be used to create cacti. After all, to create a cactus, it doesn’t matter whether the hose is torn or not, the main thing is that there is one))). These crafts are very strong and durable. In addition, they are not afraid of rain, wind and sun. It is also very convenient that they can be rearranged to any place, they will not crumble or fall apart. Looking at these works it is impossible to fall in love with them. The idea of ​​creating cacti with your own hands from a hose is very interesting and once you start creating them, you will not be able to tear yourself away from this work. Let's start making them.

To make a cactus you will need:
* Plastic clamps.
* Hose.

Method for preparing cactus:
Despite the fact that we need few materials to make a cactus, it turns out very beautiful and original. We take the hose and begin to twist it in a circle, it is better if you have some kind of device, a base, to make it more convenient to do this. If not, carefully twist the hose in a circle and periodically secure the clamps on it. Having secured the clamp, we straighten the tails outward; if it seems to you that the tails are large, then you can safely cut them later to the length you need. Ours will imitate the needles on cacti. You can make any sizes of cacti at your discretion. It all depends on how much hose you have, and the diameter of the hose also plays a role. The thinner the hose, the smaller the cactus will be. If you have different pieces of hose left, you can try to assemble a cactus from them, just paint them all the same color.

You can also make flowers or baby cacti on cacti. To do this, we cut off small pieces of the hose and attach the flower to them, and then attach it to the finished cactus. We do the kids exactly the same as big cacti only small size. Flowers can be made from plastic bottles or pieces from a hose or attach artificial flowers. The main thing is that our flowers are bright and beautiful.

To make cacti, it is not necessary to use new hoses or green hoses; old unnecessary ones will do, and if the hose is a different color, it can be painted.
Cacti from a hose will be a wonderful decoration for the garden; they are not afraid of any weather, neither rain nor wind, etc.
I hope you liked the idea of ​​​​creating cacti from a hose, thank you to the author for the interesting material.

You may have seen a toy that is a small wooden box with a side curtain lid. There is a handle attached to the lid. If you move the curtain with the help of a handle, a wooden figurine of a snake suddenly appears from the box. When the curtain is closed, the snake hides. Master class from S.G. Rykhlitsky (teacher of technological education at the Lyceum named after Titu Maiorescu, Chisinau, Republic of Moldova)

One day my grandson was brought a toy from Romania (Fig. 1.). It was a small wooden box with a side curtain lid. There is a handle attached to the lid. If you move the curtain with the help of a handle, a wooden figurine of a snake suddenly appears from the box. When the curtain is closed, the snake hides. Almost all parts of the toy are made of beech. As you know, residents of Western Ukraine make many crafts from this type of wood. Maybe this toy was made by a Ukrainian master, or maybe a Romanian one. This is unknown to me.

Having studied the principle of operation of the toy, we developed our own manufacturing technology, which is given below. General form Our version of the toy is shown in Figure 2, the device is shown in Figure 3.

Device dynamic toy"Snake": 1-cheek left (plywood); 2-side wall of the case, high ( wooden slats 6x13 mm); 3-cheek right (plywood); 4-figurine of a snake (linden); 5-sting (nail diameter 1 mm); 6-thread (nylon, diameter 1 mm); 7-curtain (wooden slats 10x17 mm); 8-handle (beech, birch); 9-side wall of the case, low (wooden slats 6x13 mm); 10-side wall of the case, intermediate (wooden strip 6x13 mm); 11-axis (nail diameter 1.3 mm).

Operating principle toys next: because one end of the thread is fixed to the snake figurine 4, and the other is in the hole for handle 8, then when the curtain 7 moves to the right, the thread is tensioned, the snake rotates on axis 11 and, thus, moves out of the body. When the curtain moves to the left, the thread sags, and the snake figure returns to its original position under its own weight.

To make a toy you will need a blank made of three-layer beech plywood (or five-layer birch) measuring 150x90 mm, a 6x13 mm strip 250 mm long from any type of wood, a 10x100 strip 100 mm long also from any type of wood, a small beech or birch blank for the handle, linden board S = 13 mm 50x60 mm for a snake figurine, steel nails with a diameter of 1 and 1.3 mm, strong thread with a diameter of 1 mm and a length of about 100 mm, PVA glue, a small-sized circular saw with a fine-tooth cutter (can be used for metal), drills with a diameter of 1.3 mm, 2 mm, 3 mm, drilling machine or a drill, a wood lathe, a pencil, a ruler, a piece of cardboard for a snake template, stationery scissors, an awl, a file, pliers, a knife, sandpaper, an awl, a sawing table, a jigsaw.

Due to the fact that the presence of a small-sized circular and lathe woodworking can be problematic; when explaining the technology, advice will be given on how you can do without them, using more affordable equipment.

Manufacturing technology of the dynamic toy "Snake"

1. Mark and cut out two cheeks from S5 (beech) or S6 (birch) plywood. If you do not have a small circular saw, this operation can be performed using a jigsaw.

2. Mark and mill a groove in each cheek and drill a hole with a diameter of 1.3 mm (drill holes simultaneously in both cheeks, folding them with the grooves inward). In the absence of a machine, the grooves can be made manually using a hacksaw by inserting two blades into it.

3. Mark and cut three slats with a section of 6x13 mm. This operation can be performed using a circular saw or manually with a hacksaw, after first securing the workpiece in the clamp of a carpentry workbench.

4. Glue it with PVA glue to one of the cheeks of the slats and insert a nail with a diameter of 1.3 into the hole.

5. Mark and make a curtain from a 10x17 mm strip and drill a hole with a diameter of 6 mm in it. If you don’t have a machine, this operation can be performed by gluing two blanks 2x17 mm and 8x10 mm.

6. Turn out the handle. If you don't have a lathe, this part can be made by hand using a knife and sandpaper.

7. Make a template for a snake figurine from cardboard.

8. Mark according to the template on the linden board and cut out the blank for the snake figurine along the contour with a jigsaw. Drill through holes in it with a diameter of 1.3 and 2 mm. Open a hole with a diameter of 1.3 mm with a drill with a diameter of 3 mm to a depth of 7 mm (for a thread knot).

9. Place the snake blank on the axle, check whether it touches the walls of the body, and if necessary, remove excess wood.

10. Finish making the snake figurine: cut the neck and head with a knife until the required shape and size are achieved, trim, insert a sting nail with a diameter of 1 mm, cut off the cap, and blunt it.

11. Assemble the product in the sequence below and test it.

Assembly sequence:

1. Thread a thread through a hole with a diameter of 1.3 mm in the snake figurine, tie a knot and tighten it into a hole with a diameter of 3 mm;
2. Place the snake figurine with a hole with a diameter of 2 mm onto the axle;
3. Glue the second cheek of the body so that the axis passes through a hole with a diameter of 1.3 mm;
4. Thread the thread through a hole with a diameter of 6 mm in the curtain;
5. Insert the curtain into the grooves, adjust the length of the thread and fix it by inserting the handle spike without glue;
6. Test the toy: when the curtain is pulled out and retracted, the snake figurine should smoothly protrude and hide;
7. Cut off the ends of the stud-axle and blunt it. Cut off the excess thread.

Note: If it is necessary to replace the thread, remove the handle from the hole with a diameter of 6 mm, push out the axle, take out the snake, thread a new thread and assemble it in the reverse order.
