Donald de Carle – författare

Now in its sixth edition, this book is the definitive work on the small precision lathe, past and present. The bulk of de Carle's original text has been retained and covers basic construction, selection, care of and accessories for the lathe, as well as its uses. Likewise, the chapter 'Lathes of the World' is still included, since it represents an unparalelled source of detailed information on lathes and accessories, the manufacture of which ceased many years ago. However, this new edition is fully up to date. The current scene is dealt with at length in the final section, 'Lathes Today', and is the result of extensive world-wide research. The directory of lathe, tool and material stockists has also been completely revised. "The Watchmaker's and Model Engineer's Lathe" is still, to quote one reviewer of a previous edition, 'The standard work on the subject'.

The repair of clocks calls for a variety of skills and crafts, few of which can be 'picked up' by bench work alone. In the horological trade, it is technical practice that the 'prentice hand' is first tried out on clocks, before attempting repair work on watches. Clocks have the advantage of possessing sizeable and robust parts and of being easier to handle. But there the advantage for the repairer ends. The sizes, shapes, complications and even the nationalities of clocks appear to be without end. Every movement has detail difference and, naturally, the defects when due for repair, are as varied. In this book, the author has dealt with the usual faults likely to develop in each type of movement in general use; from the lordly grandfather to the humble alarm. All the tools and equipment are described and illustrated, together with the ways of using them. The craftsman's most important and valuable tools of all - his skilful fingers - are shown in use in the clearest manner. As is usual in N.A.G. Press textbooks, the drawings have been specially made from parts under working conditions. A glance through the book will show their usefulness and clarity. Over 400 line drawings are used throughout and the reader is left in no doubt of what he is asked to do in following the author's clearly written technical and practical instructions.

This book's contents include: general condition of the movement; cleaning and oiling; balance pivots; fitting a flat balance spring; fitting a breguet balance spring; positional timing; further considerations when fitting a spring and observing the point of attachment; general notes on springing and timing; other methods of positional adjustment; and, timing machines."No writer can have added more volumes to the horological bookshelf than Donald de Carle, and his careful and detailed approach to the technical side of the craft has done a great deal to improve the standard of knowledge of a host of craftsmen, and has gained him readers in every part of the world. The many craftsmen who are already familiar with Mr de Carle's earlier work, Practical Watch Repairing, will note a great similarity in the attitude of mind behind both books, and, indeed, this latest volume is, to some extent, a companion and a follow-on from the previous book, for it carries the reader into what is, undoubtedly, the most exacting and skillful aspect of all work on watches."Horological Review

Dealing with a complicated watch used to be a rare job for the watch repairer, but with the popularity of the automatic, it is almost commonplace. Furthermore, the increased interest in calendar work, alarm watches, and chronographs will undoubtedly bring more and more complicated work into the workshop. This book deals with complicated work essentially from the repairer's point of view. The action of each mechanism is briefly and clearly described because understanding this is essential to proper servicing, repair and testing for functioning. Dismantling and assembly instructions are given, as well as oiling charts and - most important - hints on fault-finding and their rectification. Another essential feature of the book is that it deals with all complicated work - from the relatively simple automatic to the triple-complicated watch with chronograph, calendar and repeater work, and the very complicated clock watch. Exceptional care has been taken in the preparation of diagrams, which have been drawn from actual movements in various stages of assembly, so that the reader can actually work with the book illustrations beside the watch itself. As always with books by Donald de Carle, instructions are easy to follow and there is no reason why anyone well versed in ordinary work and able to use watchmakers' tools should not become a specialist in complicated watches and their repair.

This profusely illustrated volume forms a step-by-step instruction manual on the repair of mechanical clocks and watches. Donald de Carle was a Fellow of the British Horological Institute, and the author of many standard works on the subject of horology, who based his writings on many years of practical experience. The book begins with simple clocks and watches then proceeds to more complicated types. The tools and apparatus needed are described and illustrated. Modern types of mechanical clock are mainly dealt with, but attention is also given to the movements of older long case and fusee types as many of them are now being repaired as a result of interest in antique clocks. The chapters on watch repairing deal with chronographs and repeaters as well as self-winding mechanisms. The latest developments in ultrasonic cleaning of horological movements and their electronic timing are also described and illustrated. This work is an invaluable guide for all concerned with the repair not only of clocks and watches but also of small mechanisms in general.
