An effective way of labelling any tool storage system is to use ideograms . A big cartoon representation of the class of tool stored in any particular drawer gives an immediate input of information to the eye which can be seen from a long way off . Allows very fast ' homing in ' on right drawer as you walk towards the drawer stack .
Can be extended to sub classes by using two ideograms – one large and one small – at each location or one ideogram and a number .
Some things once common but now less used are the shadow board for frequent use tools and the project box .
Project box holds all the small tools in frequent use for one specific job in hand – so getting the box out means you can make an immediate start on your job without having to search for multiple tools individually .
Incidentally another type of storage aid , which is a cousin of the project box , is the progress tray . Once commonly used in the aerospace industry these trays have compartments to hold work in progress on multiple part + multiple operation jobs . As job progresses parts move along tray . Compartments are labelled op1 , op2 ,etc .
In particular case of smaller engine parts which are identified with part numbers from early on in manufacture each part has its own set of sub compartments numbered with the part number . These are often 2D trays – part number left to right and progress top to bottom .
Op's can include interim and pass off inspections .
Tray's were often moved on trolleys from one machine to another throughout the factory .
