Before you take on the manufacture of a wind vane by yourself, you need to study its device. Clearly, this is not the simplest design, if you remember the original functions of the device - at one time it was one of the most necessary for seafarers and was actively used for its intended purpose.
It's worth noting immediately that when you manufacture a wind vane your own hands can not do without welding. If welding is not at hand and it is not possible to get it, use a brass spike.
Before you get started, prepare a drawing of the future product. Drawings of weathercocks are easy to find on the Internet, as well as photos of weathervanes made by own hands, you need only choose the suitable model.
The main elements of the weather vane are the axle( support) and the body. It is from the combination of these elements that determines how your self-made weather vane will behave. The p
As an axis for a weathercock, a steel rod with a diameter of about 15 mm and a length of 5-12 cm is usually used. For such a support, a bearing of 2 cm in diameter is usually taken. Based on the dimensions of the bearing, it is necessary to select a pipe for the casing. That is a pipe where we will have to score the chosen bearing. For this purpose, a piece up to 13 cm long and a little less than 2 cm in diameter( about ¾ inch) is suitable. Now that all the basic materials are ready, you can start working.
