I have provided illustrations in the form of line drawings for two musical instrument-making books.
The first was Roy Courtnall's Making Master Guitars.
Roy taught me guitar making at an evening class in the early 90s and, as I was running an architectural business at the time, asked if I could draw some plans of guitars by some of the most renowned classical makers that he had surveyed. I obliged, and out of this came the idea for a book on classical guitar making that was a workshop manual but with the added perspective of these master makers' different approaches. In addition to the plans of eight makers' guitars I produced line drawings explaining many of the building techniques. My involvement in the book subjected me a large number of varied ideas on guitar making very early on in my career. The book became a classic of the genre and still sells well.
Following the success of Making Master Guitars, Roy came up with a second book in a similar format on violin making.
Roy enlisted the help of violin maker, Chris Johnson to write the workshop section and myself to produce the line drawings, this time drawn on computer.
