This book is well written and laid out, with sections to suit all experience levels of scroll saw users. However, be warned, if you're buying this book thinking it contains plans for 31 wooden geared clocks similar to the one pictured on the front cover - it doesn't. There is only one set of plans for a wooden clock - the same one shown on the cover - in the 'advanced' section and they are difficult to follow because the construction details are surprisingly brief. The remaining 30 plans are purely different scroll sawed designs that have modern quartz battery powered inserts mounted into them. A little disappointing for me.
