FWIW - don't know if this is exactly up your alley - but I find this helps me with hand/arm pain...... Is the trouble due to hitting the keys with your fingers during tuning? Have you tried using a key whacker (oops, I mean a key controlled-firm-depressor)? Here is my whacker fresh out of my tuning case in all its glory. An 18-second duct-tape job has held this assembly firmly together for about a year now. (Resting happily on some dusty piano plate somewhere is my more fancy epoxied whacker.) https://www.moypiano.com/ptg/files/attachments/14/4f/e6/ab/KeyWacker.JPG http://tinyurl.com/zgv9 Below is said tool in use. https://www.moypiano.com/ptg/files/attachments/39/71/46/cf/ KeyWacker2.JPG http://tinyurl.com/zgvc Keeps fingers happy.
