  • Interchangeable parts

    serch.it?q=Interchangeable-parts

    Interchangeable parts are parts (components) that are, for practical purposes, identical. They are made to specifications that ensure that they are so nearly identical that they will fit into any assembly of the same type. One such part can freely replace another, without any custom fitting, such as filing. This interchangeability allows easy assembly of new devices, and easier repair of existing devices, while minimizing both the time and skill required of the person doing the assembly or repair. The concept of interchangeability was crucial to the introduction of the assembly line at the beginning of the 20th century, and has become an important element of some modern manufacturing but is missing from other important industries. Interchangeability of parts was achieved by combining a number of innovations and improvements in machining operations and the invention of several machine tools, such as the slide rest lathe, screw-cutting lathe, turret lathe, milling machine and metal planer. Additional innovations included jigs for guiding the machine tools, fixtures for holding the workpiece in the proper position, and blocks and gauges to check the accuracy of the finished parts.

  • HMS Hood

    serch.it?q=HMS-Hood

    HMS Hood (pennant number 51) was the last battlecruiser built for the Royal Navy. Commissioned in 1920, she was named after the 18th-century Admiral Samuel Hood. One of four ordered in mid-1916, Hood had design limitations, though her design was revised after the Battle of Jutland and improved while she was under construction. For this reason, she was the only ship of her class to be completed. Despite the appearance of new and more modern ship designs over time, Hood remained the largest and most powerful warship in the world for 20 years after her commissioning, and her prestige was reflected in her nickname, "The Mighty Hood".Hood was involved in several showing-the-flag exercises between her commissioning in 1920 and the outbreak of war in 1939, including training exercises in the Mediterranean Sea and a circumnavigation of the globe with the Special Service Squadron in 1923 and 1924. She was attached to the Mediterranean Fleet following the outbreak of the Second Italo-Abyssinian War. When the Spanish Civil War broke out, Hood was officially assigned to the Mediterranean Fleet until she had to return to Britain in 1939 for an overhaul.
