Claude,
A very useful book is "PRACTICAL ASTRONOMY: A User-friendly Handbook for Skywatchers", by H. Robert Mills and published by Albion Publishing of Chichester, Sussex, England. ISBN 1-898563-02-0 (hardback) or 1-898563-00-4 (paperback). Reprinted 2000. Don't be put off by the title. It is wide ranging but Chapter 2, (The Sun and Sundials) covers various sundial designs and shows how to make them using card, sticks, string and such like. It has a fair amount of mathematics but the author wrote it with the pocket calculator in mind. Beware of some rather odd type-setting in places! Hope you find it useful.
