The good master is always a stock of various parts, components, metal fasteners. But often to keep them all accounted for in the raw unheated outbuildings: the barn, the loggia or the balcony. The metal is not rusted, it is better to place it in an oil “bath”. Associate, for example, bearings of the same size copper wire and dip in a shallow container with butter — you will have a reliable storage for them. At the end of the wire fasten a tag with the number of bearings, and the top, close the reservoir cap.
