Hi Doug Contact David Stanwood is the master of those thing David C. Stanwood" <Stanwood@tiac.net> Serge -----Message d'origine----- De : owner-caut@ptg.org [mailto:owner-caut@ptg.org]De la part de doug condit Envoyé : 2 mai, 2001 01:25 À : caut@ptg.org Objet : leverage and touchweight To the list, I am a high school student who had made a computer automated device which measures the Active touch depth (key dip minus aftertouch)of all 88 keys of a piano action in less than an hour, and calculates the leverage from this. The device takes 3 samples of each key. If there is a deviation of more than .001" it takes three more samples and averages the numbers. It also takes the touchweigh of the action. This information is collected and graphed so the information is very accessible and easily saved so a record can be kept on the history of each piano tested and worked on. I am competing at International Science and Engineering Fair in San Jose, California next week and I need feedback from professionals in this field on the importance of these measurements and how useful this type of device would be to technicians who rebuild and or regulate actions. I would appreciate any responses, as this is important to my project. Thank your for your time.
