“The Perfectionists” How Precision Engineers Created the Modern World

By: Simon Winchester

Narrated by: Simon Winchester

Simon Winchester has a remarkable ability to simplify, detail, and vivify history’s complexity. Winchester is not new to this listener. His erudition, writing, and narration are a pleasure to read or hear. His story of the origin of the first Oxford English Dictionary, is a fascinating recollection of Dr. William Minor who shot and killed a stranger on a London street. Dr. Minor was imprisoned in an asylum for his aberrant behavior but became an important source of information for James Murray, the leading lexicographer of the “Oxford English Dictionary”.

“The Perfectionists” is about the advance of the world economy from the perspective of entrepreneurs driven to succeed. Their success, in Winchester’s opinion, is based on understanding and capitalizing on the value of precision.

Though one may go back to the first century to find the first steam engine, it is the invention of James Watt, and the improvements of Matthew Boulton, and Sir Charles Algernon Parsons in the 18th and later 19th centuries that perfected steam engine utility and power. Watt created the steam engine, Boulton helped Watt perfect the steam engine for industrial use, and Parsons expanded its utility by creating steam turbines to power the propellers of steamboats. Each played a role in making steam engines more efficient with precise design and milling refinements that provided more power and wider utility.

With the advent of the industrial revolution, Winchester explains how speed and quality of production were geometrically improved by focusing on precision. He offers several industry examples, including weapon manufacture, automobile production, camera refinement, telescope resolution, airplane manufacture, watch making, and CPU design which now leads to the A.I. revolution.

Winchester tells the story of the French that insisted on standardizing parts for gun manufacture to increase the speed with which repairs could be made for damaged weapons. Winchester recounts the war of 1812 when Great Britain bloodied the nose of America by routing the capitol’s volunteer defense because of a lack of useable guns. He tells the story of an American rifleman with a broken trigger on his rifle who chooses to run from a British onslaught because trigger replacement would take two weeks for customization to fit his gun.

Honoré LeBlanc, a French gunsmith during the reigns of Louis XV and XVI, created the idea of interchangeable gun parts in the 18th century. Though it came to the attention of Thomas Jefferson, it did not catch hold in America until after the war of 1812. There was an effort by America to standardize parts in the early 1800s but Eli Whitney (the inventor of the cotton gin), hoodwinked the American government into a contract for standard gun parts that never materialized.

Winchester notes Whitney knew nothing about guns and hired a crew of customizing gunsmiths who manufactured unique weapons that could not be repaired with standardized parts. Because the parts were manufactured by individual craftsman, the guns produced were not interchangeable. They did not have precisely manufactured parts that would allow interchangeability. Whitney gave a demonstration to the government with only one gun that he assembled in front of Jefferson and a government committee. He did not demonstrate any repair with standard parts. Jefferson fell for the false presentation and initially lauded Whitney. This demonstration was in 1801 which explains why a soldier might have fled because of a broken trigger in the War of 1812.

Winchester explains standardizing and precision making of gun parts were an essential step in the industrialization of America. Standardization and precision-made interchangeable parts became the touchstone of success in the automobile industry in the 20th century. Winchester tells the story of Rolls Royce and Ford Motor companies to make his point. Both Royce and Ford recognized the importance of precisely made standard automobile parts to garner their success in the automobile business. Though their route to success is precise manufacture of automobile parts, the wealth they created for themselves was quite different.

Ford became one of the richest people in the world while Royce became wealthy but not among the richest in the world. Royce chose to pursue perfection of every part of the automobile which limited his unit production and increased manufacturing cost. Though Ford perfected standardized mechanical parts, they were precisely designed only for functionality. Ford added the dimension of standardized labor to the manufacturing process. By creating an assembly line of laborers with precise replaceable mechanical parts, Ford could produce more automobiles than Royce in a shorter period of time.

The point Winchester makes is perfection of standardization (production of precisely tooled engine parts) is a cornerstone of successful industrialization. Royce expanded the concept to every part of an automobile while Ford focused on replaceable mechanical parts of the automobile.

Winchester tells a story of ball bearing manufacturing during Henry Ford’s reign when some automobiles were failing. The bearing manufacturer proved it was not their bearings with tests that showed the bearings were perfectly within precise measurement requirements. What Ford realizes is that the ball bearings were milled exactly the same and met the precise dimensions required. The problem was found to be the assembly line and human assembly mistakes. One thinks of the loss of precision in Boeing aircraft today and wonders what that means for Boeing’s future if it is not immediately corrected.

Jet engines are precisely manufactured marvels of aviation. However, a tiny flaw in one oil pipe within the engine nearly caused the loss of over 400 passengers. Winchester explains Jet engines are dependent on superheated gas exchange that, if not properly cooled, will damage the engine. Every engine has a series of drilled holes that allow ambient air to cool the engine during flight. The holes are drilled in precise locations throughout the engine louvers and oil pipes to keep the engine from overheating. One of the oil pipes holes is in the wrong location which caused the engine to overheat after many flights. The failure of human oversight of the automated process and final checks by the manufacturer are the underlying cause of the near catastrophe.

More examples of the importance of precision are wonderfully offered by Winchester in “The Perfectionists”. His examination of the tech industry is as prescient as his analysis of the automotive industry and airline industry. He covers Moore’s law and how technology is advancing at an accelerating pace while inferring humanity may be at a turning point. That turning point is the crossroad between human and machine decisions about the future.

Winchester infers craftsmanship does not mean precision is to be sacrificed. He recalls the emphasis on precision in Japanese culture where many craftsmen assembled and repaired Seiko watches to revitalize the brand in the late 20th century. Precision is not a lost art whether work is done by machine or a craftsman, but the human factor remains a critical component of both processes. The point to this listener is that precision is only a part of what has advanced the welfare of society.
