To All: Coil tapping is usually taken care of at the factory. All good rebuilders do this routinely because they know that this will save them several rough tunings. The technician in the field should not have to do any additional coil tapping on well made pianos. I have a 25 year old Baldwin SF10. I lightly tapped two pin coils. Nothing changed pitchwise. Perhaps there might be some change on a very new piano but I don't have one available just now. Jim Coleman, Sr. PS Of course if I tapped it hard enough to drive the pin or break the beckett, I might possibly be recording a different story here. Just remember, if a little downbearing is good, is a lot of bearing better? No way Jose! (sorry, I didn't know how to put an accent over the e).
