"Slightly unscrewing tuning pin " (loose tuning pin. a technique of restoration)

Here a complete "scenario" as a way to apply a tighten loose pin:

1. Loosen the pin and, using a thin but hard screwdriver with a thin stinger remove the tip of the string from the hole of a pin (becket).
2. Do not removing the string from a pin with considerable effort compressed fingers, use a T-bar, starting unscrewing tuning pin from the hole. This can be 3-5 or more complete cycles counterclock-wise. It is very important to stop it's when your hand will feels the maximum pressure between a pin and "a body of wood". Should have the feeling that you as pull it's pin like the feeling when we use pliers, pulling a nail out of wood.
3. Set the end of the string into the hole of a pin and gradually use very slow movement, begin to screwing . If this couple string bring almost to the desired tone it's couple pin. Before that as to tune loose pin.

4. Have strong pressure by own hand (fist) directed to the iron plate, gradually and slowly twisting a pin. In the beginning tuning is necessary to tighten a rings string using a screwdriver so it's located as closely as possible to each other. 5. In begin to make tuning couple pin. 6. Set the tone just above the standard pitch, to ensure that "unscrew pin" has enough friction.

7. Set "last and standard pitch "our "tightening pin"

It can make any layman.
Good luck
