Lance,
Richard Madden gave credit to his sources of information:
"From the first time I saw pictures of Stuart Mortimers signature twist work, I knew I wanted to try one myself, but I feared it was too difficult and time consuming. Stuarts book, Techniques of Spiral Work- A Practical Guide to the Craft of Making Twists by Hand, and an article in the May 2006 issue of Woodturning were the sources of inspiration and also great learning tools."
It has been nearly a week since your post. Are you still searching for that Deltagram?
