Board hammer in a few nails to pass through them the wire, as shown in the figure and stretch it, storing the coil or drum. Wire, covered with insulating enamel, stretching in this way is not recommended — it is easy to damage the protective coating. For its straightening better to use another method. Will zahrajte the end of the wire and to the opposite end tie a stick — a wooden stick. Pull the loose end of the wire — it will become as straight and smooth as in the previous case.
