PREFACE

The Audel line of books has been a mainstay for mechanics, millwrights, machinists, electricians, and engineering personnel since the early 1900s. This author has a personal collection of many of the early Audel texts. While reading books composed in the period from 1913 to 1928, it is interesting to note that it was not the degreed mechanical or electrical engineer who calculated the shaft fit of a bearing, the belt length for a drive, or the voltage required for a circuit. A knowledge of math was expected of craftsmen. They did the calculations and also possessed the craftsmanship and skill to effect changes in machinery and circuitry to keep the process running.

In today’s intensely competitive world, the old adage “Jack of all trades, master of none” is no longer a truth. Many facilities depend on a new type of employee, the multicraftsman, who possesses in-depth knowledge of many crafts and can apply that knowledge to keep things running. Where you work now, you may discover that the people who keep their jobs are those who understand that “survival of the fittest” means knowing more than just one trade—and being good at them.

The old Audel guidebooks stressed calculation and insisted that the craftsman be able to figure things out on paper. But the old books did something that newer books seem to have forgotten. They used worked-out examples so workers could relate the concepts to their jobs. It’s easy to learn a formula in class or remember it for a test, but how about weeks or months later? At that time, the review of a worked-out example really helps to make things happen.

Too many small books provide tables, charts, and formulas but never show how to use them, nor do they provide concrete examples of how this information can be used on the job to make the craftsman faster, better, and more sure that the job will be a success.

Books in the Audel Mini-Ref Series are geared to the craftsman who wants to learn individually outside of a classroom as well as the tradesman who was taught but needs a few memory joggers to remember what was learned earlier. The Mini-Ref Series uses real examples to show how to make the calculation, how to use tables to find the right answer, and how to read graphs to check the theoretical against the real-life situation.

ABOUT THE AUTHOR

Thomas (Tom) Bieber Davis owns and operates Maintenance Troubleshooting, an engineering business dedicated to diagnosis and repair of mechanical rotating equipment. For the past 40 years, Tom has worked in all 50 states in various industries. Tom’s mantra, “Machinery does not understand politics, only the laws of physics,” explains his insight into how rotating equipment works, as well as how it fails. As a practicing mechanical engineer, Tom enjoys teaching on-site classes of mechanical personnel about pumps, fans, and bearings, as well as writing on these subjects. Tom says his mother, Verna Bieber Davis, was the first multi-craftsman he ever knew. She could do anything. He can easily be reached by e-mail at [email protected], and he answers his mail.
