Weathervane with their hands : photos, drawings , instructions

materials weathervanes

Traditionally spinner is made of steel or copper.Less commonly, you can find quite expensive and complex to manufacture wrought iron weathervane.Almost did not make due to the impracticality of pinwheels of experimental materials (in the course are plywood, bottles and more) - this option is not desirable, although it is also the place to be.

What is Vane: photo

Before developing its own unique design and start designing a weather vane on its own, read with the necessary components of this meteopribora:

• body, submitted a 13-centimeter piece of three-inchtube;
• axis of 45 cm smooth valves 10 mm thick;
• Cover-cap for the case with pre-drilled 10-mm hole in the middle;
• wind rose in four 20-inch steel rods of 6 mm thick;bars fixed to the lid at an angle of 90 degrees to each other at such a height, so you can freely observe their testimony from the ground;rods are attached to the edges of the letters-designate areas of the world, often in Latin;
• vane, which is often made of a thin copper or stainless steel.

How do weathervane own hands: step by step instructions

Creating a working weather vane - is not such a difficult task.If you follow the instructions correctly, you all will certainly succeed.

• Step 1. On the case top to do the thread and put it below the bearing size (inner diameter of the bearing must be equal to 9 mm).
• Step 2. Tie the twig should be machined on a lathe or by hand to a thickness of 9 mm.If you plan to do this by hand, carefully check the accuracy of the parameters with a caliper and try on the item on the bearing size.
• Step 3. Weld the compass rose on the housing cover and screw it on the tube.
  

  Note!Given that the main task of modern weathervanes - decorative, try to carry out welding work with a jeweler's precision.

• Step 4. The axis is inserted into the pre-drilled hole in the lid;the main goal - to get exactly into the bearing bore and ensure ease of movement of the axis.The axis must be fastened securely within the bearing.
• Step 5. Cut a thin stainless steel cap slightly wider than the diameter of the body.Weld it over the cover to protect the unit from rain.
• Step 6. vymeryat desired axis length and cut the excess.
• Step 7. The most decorative step: manufacture of wind vanes.It was she who determines decorative items.The easiest way is to use a sketch, although the desire to develop before you can work out on their own drawings.
• Step 8. vane is attached to the axle by means of welding or soldering neat.

Installing a weather vane on the roof

Before installing vane on the roof of the gazebo or at home you need to fill the body with lithological (or grease).Armed with a simple compass, set exactly the compass rose.

several options for installing a weather vane:

• easiest way to fix the housing on the edge of a vane circular flange;
• fix by clamps or flat plates;
• can set the wind vane on the cap chimney with flat strips of spacers.

If there is a need to calculate the approximate strength of the wind, then the instrument should be placed loosely hanging metal plate.According to her deviation from the vertical and you can determine this value.
With proper design and installation of a weather vane it will react even to the slightest breeze active torsion.
