In the repair of equipment there are times when a small detail falls into such a place, where to get it very difficult. And if a piece fell inside some mechanism? Then the continued operation is fraught with serious breakages.
But do not hurry to disassemble the mechanism. For fetching the details try using the following method: insert into the mechanism of the steel rod to contact with the fallen item. Then to the upper end of the rod attach a strong magnet, and, without taking it, carefully remove the shank — the item will be retrieved along with it.
