Hello, I have been invited to lecture at our piano pedagogy classes in the past. I usually have as materials different action parts, i.e. hammers, wippens, backchecks, pieces of various felt and buckskin, tuning pins, etc. Also, if you have an old piece of pinblock material handy, you can cut through a section where the holes are and show the pins in place. I also bring in my action models and I have printed copies of vertical and grand actions for each student. I like to discuss things that they are not likely to hear in their normal class discussions,such as; construction, amount of accumulated string tension (that's always an eye opener), what happens when the key is depressed (in slow motion), setting the pitch, comparing the beat of the string against the fork. Many of the things we take for granted as technicians are extremely interesting to students and professors alike, and don't be afraid to ask for questions. Good luck and let us know how it goes.
