The second edition of 'Synchronome: Masters of Electrical Timekeeping'

This post was written by Charles Ormrod

Robert Miles’s landmark work, Synchronome: Masters of Electrical Timekeeping , sold out a few years after its original publication in 2011. Since then, copies of this highly sought-after book have been selling for several times the original cover price of £50.

The AHS is therefore delighted to announce that a long-awaited second edition is now available, made to the same standards as the first, hard-backed and thread-bound, at a new low price of just £25 plus postage.

As a humble labourer in the vineyard of the second edition, assisting James Nye with administrative work but certainly not with Synchronome expertise, I’ve had a first-class opportunity to learn about the pitfalls of editing, proof-reading, and the finer points of book production.

The possibility of a second edition was mooted some years ago, and revisions to the first edition had been contributed by Bob Miles himself, Derek Bird, Norman Heckenberg, Arthur Mitchell and others.

One of my first jobs was to combine these various sets of revisions into one document, eventually about eight A4 pages long, for presentation to the designer of the first edition, Phil Carr. Phil very generously made no charge for all the work of entering revisions into a new version of the original book’s electronic file.

Examples of the high-quality colour illustrations and diagrams found throughout the book.

Double-checking the changes and exploring disagreements between contributors led to many absorbing hours searching for clarification. I now know far more than I did about the history of sonar and the extent to which Second-World-War sonar sound-pulses fell within an audible range (which depended on whether the listener was a fit young sailor or an old sea dog).

I also learned about the Doppler effect on the sound of swinging tower-clock bells, the problems of reproducing the appearance of pre-war electrical flex, alternative cabinet-making methods applied to Synchronome cases, and the best method of setting up the suspension of a Synchronome pendulum.

I must admit I hadn’t quite realised that high-quality hard-backed books, such as the first and second editions of Synchronome, really are still made by sewing groups of double pages together with thread. A machine does the sewing of course, but the principle is broadly the same as with the earliest surviving bound books of the eighth century.

A thread-bound book is much easier to use than a glued paperback because the pages naturally fall flat when the book is opened, and thread-binding lasts far longer.

This second edition of Synchronome: Masters of Electrical Timekeeping is dedicated to the memory of its author, who died earlier this year in the knowledge that work on a new edition was under way. The book is available to order on the AHS website via this link.
