Frankly I was a little disappointed, as the title promised so much, which common sense would tell you is impossible to deliver in a book this size. At best it can only be a GUIDE. The measurements at the back, are, I think the most useful elements. The worst are the diagrams, which are immensely confusing and repetitive. If a picture says a thousand words you'd want to be very selective about labels on a drawing.
I think many of the design drawings, especially of the bridge, could have been reproduced in full scale!! Not much use for a template otherwise. Some of the instructions (eg fitting a soundpost) are also a bit wordy, and perhaps a series of little diagrams would have been better. There is virtually no sound advice on how to actually repair, eg how to take apart a damaged violin, and so the fact of the book's title really bamboozles me! No real advice on gluing, ie what viscosity for what job etc, which would be essential knowledge. Yet there is so much detail on quite skilled major jobs like making a saddle, resetting the neckpiece, cutting your own bridge(???) etc etc. Intructions like "remove the neck" are not very useful unless you say how.
Generally I got the feeling that the writer did not know for whom he wanted to write this book: beginner, amateur or advanced student of musical instrument technology, and so is not in touch with his intended readership. The writer advises "..familiarize yourself with all the figures in this book ....." (page 4) and in that job alone, you will have your work cut out (excuse the pun!).
