I am working on a 1991 Kawai KG-1E (5'4") in a church. Among other things, I replaced key bushings. While easing keys, I realized that the balance pins are installed perfectly perpendicular to the rail, rather than angled back. Should this change my approach to easing the balance hole? I was taught to lift the front of the key anywhere from 1/4" to 1" while the back of the key rests on the back rail, and to ease for free fall of the key. It seems to me that on any piano, at some point lifting too far and easing to allow for a freely falling key will cause chucking (pulley key). In this particular case, does having the pins perpendicular require less, or no, lifting at the front, but rather lifting front and back of the key to check balance hole fit?
