(2) Industrial Production: Manufacturing
(a) Tools
(1) Let cutting tools grow dull. They will be inefficient, will slow down production, and may damage the materials and parts you use them on.
(2) Leave saws slightly twisted when you are not using them. After a while, they will break when used.
(3) Using a very rapid stroke will wear out a file before its time. So will dragging a file in slow strokes under heavy pressure. Exert pressure on the backward stroke as well as the forward stroke.
(4) Clean files by knocking them against the vise or the workpiece; they are easily broken this way.
(5) Bits and drills will snap under heavy pressure.
(6) You can put a press punch out of order by putting in it more material than it is adjusted for—two blanks instead of one, for example.
(7) Power-driven tools like pneumatic drills, riveters, and so on, are never efficient when dirty. Lubrication points and electric contacts can easily be fouled by normal accumulations of dirt or the insertion of foreign matter.
(b) Oil and lubrication systems are not only vulnerable to easy sabotage, but are critical in every machine with moving parts. Sabotage of oil and lubrication will slow production or stop work entirely at strategic points in industrial processes.
