Dear Dianne, There is a small book by Philip Garrerd (sp) which is optimum for your intent. I have several copies that I will not be using, if I can find them, that I am willing to sell at cost, which is what I charged the students in the pedogogy classes I participated in. Take action parts, hammers, shanks, wippens and action models to the class with some tools. Make changes in the actions models so they can feel the differences. Talk about regular tunings and regular maintenance. I some outlines I can share if you are interested. Newton nhunt@jagat.com
