As reviewed in The Australian Woodworker Issue 58

There is now a bewildering array of books for the novice woodturner to choose from - but nowhere near so many for the more experienced woodturner who is looking for 'something different'.

Perhaps this is one of the reasons why many woodturning exhibitions throughout the world consist of a relatively small amount of spindle work and a large number of not all that dissimilar bowls.

In this book, Jack Cox, who has been a woodturner for over 30 years, seeks to redress the situation.

He explores three extensions to basic woodturning - off-centre, coopered and laminated work. While these are by no means the only techniques that might be classified as 'beyond basic turning', the author fills around 250 pages in discussing them. His writing is careful and methodical and his descriptions, clear and unequivocal.

Because of the importance of preparation in much of the work dealt with in the book, a significant amount of space is given to 'segmentation principles', 'design and marking out' and 'the nomogram'.

Nomograms, for those who may be unfamiliar with them, are tabular bar style diagrams used to solve (ie. to supply the unknown factor in) simple equations. In these days of calculators and computers, they have all but disappeared from engineering, but Jack Cox shows that by learning a little about them, they can be extremely useful in calculating angles, segment lengths etc. when setting up segmented work.

The last third of the book is devoted to a series of Projects. Some of these are not only excellent examples of the type of work considered in the book, they are also very attractive pieces - worthy, we suggest, of any woodturner's efforts.

The offset straight-segment platter, curved-segment platter/bowl, curved segmented goblets and the cutlery handles (produced by the unusual technique of off-centre cage turning) all fall into this category. For those who have mastered the basic skills of woodturning, this book will push back the horizons of opportunity.
