Advice 1: How to wind the inductor

Coil inductance is a device able to store electrical energy in a magnetic field. These inductors are used in various selective circuits and smoothing filters. Coils of inductance it should be borne in mind that their electrical characteristics are determined by the number of windings, the properties of the magnetic material and configuration.
How to wind the inductor
You will need
  • Copper wire, frame, winding machine, Shuttle
Instruction
1
Determine the type of spool that you intend to make. Depending on the usage conditions and the design coil inductance are divided into low and high frequency. For low frequency coils you'll need to fabricate a magnetic core (core) of steel plates. In the high frequency coils the core is either not used or it is made of a nonmagnetic material. This core allows without changing the turns of the coil to change its inductance.
2
Pick up the wire for winding coils. As a rule, in coils both types use copper wire of different cross-section (copper has a low resistance). Pick up the wire in the insulation, depending on the purpose of the coil (often the preference should be given to the enamel insulation). The coil used in the high-frequency short-wave range, to reduce losses wound non-insulated wire.For winding coils of high quality factor used, for example, in narrow-band filters, use stranded wire consisting of several twisted together wires with enamel insulation.
3
Determine the diameter of the wire to evaluate the possibility of its application in the coil. In the absence of micrometer wrap a few dozen turns of wire on a pencil or other suitable rod (tightly, turn to turn), and then measure with a ruler the total length of the winding and divide by the number of turns. The more turns and tighter winding, the more accurate the measurement result.
4
Fabricate the coil form. At home when constructing improvised apparatus frame can be made from paper, organic glass, cardboard. Small size frames are manufactured from your camera roll, which you must first remove the emulsion. For rigidity, use multiple layers of film. This film fabricated the cheeks of the frame, gluing them celluloid glue.
5
If you master the contoured coil of the receiver, place it in the screen to protect from external electromagnetic fields. For the manufacture of screen use sheet copper or aluminium. The diameter of the screen, make the diameter of the coil about three times.
6
Winding wires on the coil produce manually or on a special winding machine (depending on the type of frame and core). The coil is made on a circular ferrite core, winded with a special device (Shuttle).
7
If you need soldering enameled wire, first remove the enamel. This is easily done by holding the wire in the flame of a burning match, Stripping with a sharp knife or rubbing the wire wool soaked in acetone.

Advice 2: How to make an inductor

Coil inductance is a rolled into a spiral conductor, storing magnetic energy in a magnetic field. Without this element it is impossible to build neither a radio transmitter nor a radio receiver, for use of the device wired connection. And TV, to which many of us are so accustomed to, without coil inductance unthinkable.
How to make an inductor
You will need
  • Wires of various sections, paper, glue, plastic cylinder, knife, scissors
Instruction
1
The basis of the coil inductance is a conductor. Around the conductor passing through it a current the magnetic field is always present. The strength of this field depends on the strength of current in the conductor. Another way to strengthen the magnetic field to collapse the conductor into a spiral. This is nothing more than a coil of inductance. The smaller the coil diameter, the more turns the stronger the magnetic field generated by the coil. Hams usually wound these coils on their own.
2
Inductance is the ability of the coil to create a magnetic field. Inductance is measured in Henry (H).
3
Coil inductance is not produced in the form of standard parts with standard specifications, as calculated and manufactured for each specific device separately. Therefore, in the manufacture of coil you will need to first consider the characteristics of input and output signals of your radio.
4
For VHF and short-wave oscillatory circuits are made coils with few turns of thick wire. Some of these coils don't have a frame.
5
For transmission and reception of radio signals at medium and long wavelengths are used multiturn coil (single-layer and multi-layer). To make the frame for these coils you will need paper or plastic.
6
The number of turns of the coil when you configure the radios and other equipment will have to pick up experimentally, changing the inductance of the coil. You can do it otmuchivaniem and Domitiana of turns of the coil, but this method is not quite useful in practice. This files most often placed inside the coil pull out a core of special magnetic material. This can be alsever (an alloy of aluminum, iron and silicon).
7
Magnetic cores concentrate the magnetic field of the coil, thus increase its inductance. With this you can reduce the number of turns of the coil, which leads to the decrease of its sizes and dimensions disturbed.

Advice 3: How to wind cord on the reel

As well in the early morning to give up on fishing! The fresh smell of wild flowers, birds chirping and the first rays of the sun a soothing effect on the human psyche. To maintain this state of mind, it is necessary to avoid any trouble during fishing. And this before you should care, in particular, and about the proper winding of the cord on the spool fishing.
How to wind cord on the reel
You will need
  • - solid cord;
  • - reel with the spool;
  • - metal rod (a pencil or ballpoint pen);
  • - thimbles (finger cots or pieces of foam).
Instruction
1
Choose snap for fishing. It can be quite strong and cheap nylon monofilament; woven in the form of a hollow pipe and has a good resistance to tear Dacron fishing line; cord, having a lead core; stranded or solid cord.
2
Use wire cord if you plan to fish deep water with a strong current. It is the lack of linear expansion and good opposition to a strong current. However, a single-core cord with twist easily torn, so it requires only the right winding coils.
The cord can be any color
3
Put on fingers sewing thimbles or purchased in a drugstore fingertips. You can hold between your fingers pieces of foam. So you can protect your hands from damage during winding of the cord on the spool. And will be able to avoid staining of the hands in the color of the cord, which sometimes paint the shed.
4
Put on a horizontal surface coil with a cord and start peremanivanie. To fishing would come out of your hands, insert it in the core of a pencil, metal rod of suitable diameter or a pen. If the household is not able to help in the winding of the cord on the spool, hold the rigid rod with coil independently using his feet.
5
Start to wind on a spool with a coil cord with a certain tension. If the coil winding was done poorly, then when casting heavy baits past the coils rewound stronger than the underpad. And it will be difficult to avoid formation of "beard" when casting spinning. Strong winding coils will reduce the durability of the cord and will have a negative impact on the spool. Empirically to get the optimal tension and density of the winding.
6
Make a regular thread # 10 for hand sewing the backing. It is the connecting link between the cord and the reel. For long distance throw rod when planting fish soft sewing thread will not spin. You will not lose control of caught fish. In addition, the weight of the backing from a simple thread much easier. And it positively affects the balance of a spinning.
7
Do not wrap the cord on the spool through the side – this leads to flushing of eyes or the formation of "beards". Optimally to the edge of the rim should remain up to 1,5 mm. With a larger distance to the rim will be difficult to carry out casting. Search for "Golden mean". Under optimum tension on the cord during winding and the height of his fishing reel, and with proper maintenance, you will certainly be successful fishing.
