Tip 1: How to make a weathervane
For many centuries, decorate the house andhelp to always be aware of the direction of the wind installed usually on the roofs of the houses weathercocks. If you want to make a weather vane and yourself, then you need to know some subtleties of its production and installation.
Instructions
1
A weathervane is a metallic flag withcounterweight. This flag under the action of the wind turns, and allows us to determine its direction. More precisely determine the direction of the wind will help install the weather vane on the wind vane.
2
The average size of the standard weather vane is 400x800x70 mm for the house. For a gazebo, you can take a weathervane and a smaller one. There are weathercocks from the axis or pillar, flyugarki and roses of winds.
3
A weather vane stand can be made from a smalla piece of pipe length of 12.5 cm and up to 1.5 cm in diameter. The thread is cut in the upper part of the stand, the bearing is fixed in the lower part. To the roof, the weather vane can be fixed with steel strips fixed on the side of the rack. The fastening of the strips should not interfere with the free rotation of the wind vane.
4
The weather vane cover is made of steela workpiece having an internal thread. The top of the weathercock can be decorated with a rose of winds - thin metal tubes pointing to the sides of the world. Above the weathercock can be covered with a protective cap.
5
The weather vane itself can be made of stainless steel in the formanimal or man, or just some object or figure. Then the resulting figure is bolted or welded at the very top to the tube of the rack.
6
Installation of weather vane requires the presence of metalbracket, a drill with a metal drill, a rivet with a combination of rivets, a washer, washers with a nut, a wrench and a swivel and consists of several stages.
7
The cap of the pipe is fastened diagonallymetal strip-brace (2 mm thick). This strip is bent at each end by a few centimeters. The bracket is then fastened with a rivet with combined rivets.
8
A hole drilled in the hood with a diameter equal to the diameter of the weather vane. At the end of the rod, the thread is cut with a thread. It is better to do this in advance.
9
Further into the hole of the cap is inserted an axisweathervane, and the washer is put on top and the nut is wound. The rod should be twisted into a brace, after which it is necessary to orient the wind rose against the sides of the world. Help in this compass.
10
Another nut with a washer is wound on the other end of the weather vane rod. This ensures that the weather vane is tightly fixed to the bracing. On this work on the installation of weather vane can be considered complete.
Tip 2: How to make a weathervane from improvised materials?
Weathercocks are placed on the roofs of homes since ancient times. These adaptations are convenient in that they allow you to determine and predict the movement of the wind. From the variety of modern weather vanes is breathtaking.
On the roofs of the houses you can see a variety of weathercocks, differing in design and complexity of manufacturing. Elementary weathercock can be made from the most improvised materials.
The weathervane indicates the direction from which the wind is blowing. If the wind blows from the north, then the weathervane will point north.
Weathercock from simple pencil and straws for a cocktail
You will need: - a simple pencil with an eraser on the end - a straw for a cocktail - thick paper - a pin - an adhesive - a marker - a plastic or a cardboard beaker.How to make a weathervane
Cut each end of the straw so thattwo longitudinal slits were obtained. Cut out two triangles from thick paper. Insert them into the notches in the straw. One triangle is an arrow, and the other is a tail. The "arrow" will be inserted into the notches by the base, and the "tail" - the vertex of the triangle. Secure the triangles with glue. Insert a pin into the eraser of the pencil, piercing the straw through it in the middle. The straw should rotate freely. Insert the pencil into a plastic or cardboard beaker. Secure the pencil with glue. At the bottom of the glass, glue a square of thick paper. Mark compass directions on it. Now you can go outside and see where the wind blows from.Simple and small weathercocks are put on lawns, attached to baby carriages so that during walks in the wind the child could observe how the device spins.
Weathervane from plastic bottle with sand
You will need:- a bottle with a lid - a square of thick paper 20 by 20 cm - a square of thick paper 5 by 5 cm - 2 thin wooden sticks, for example, for shish kebabs, 5 cm longer than a bottle - a pencil and a thread - 1 cup sand - scissors.How to make a weather vane
Fill the bottle with earth. Tie the sticks at a right angle 5 cm from the end. Draw a triangle of 5 by 5 cm on a small square of paper. Cut it out. Glue the triangle to one of the short ends of the stick so that it looks in the opposite direction from the cross. This is the arrow of the weathervane. Make a hole in the lid. Tighten the bottle with a lid. Insert the long end of the stick without the arrow into it. Immerse the end of the wand in the sand. The wick must not get stuck, but spin freely. At each end of the cardboard box write compass directions. Put a large square on the ground in the right directions. They need to know, then to determine the movement of the wind. To determine the directions, use the compass. Observe the movement of the arrow. It shows where the wind blows.Tip 3: How to attach a weather vane
The fixing and correct installation of the weather vane on the roof of the house plays an important role, since the operation of the device depends on the location of the arrowheads and the reliability of the structure.
How to attach weathervane? Also with its decorativeThe weathervane function serves to determine the direction and force of the wind, and so the fasteners must be strong enough. In addition to reliable fastening, it is necessary to properly adjust the weathercock during installation so that the readings are reliable. The weathervane is made of metal or wood, but the wooden figures are short-lived and may lead to failure in the testimony. In addition, the external arrangement of the structure provides for the deposition of precipitation on it. Therefore, it is rational to choose a metal (steel) weathercock.
