Hi Jeff. When I don't have sufficient after touch, I raise the hammer line (less blow distance). It is also good to check the rest position of the jack (aligned with the knuckle core border). Best regards. Stéphane Collin. ----- Original Message ----- From: Jeff Miller To: pianotech at ptg.org Sent: Sunday, January 07, 2007 4:57 AM Subject: regulation problem I am trying to regulate a Yamaha G1 grand. (trying being the key word here). This is my first regulation for pay and boy is it giving me problems. I have set key height at 45 .5 mm, blow at 47.5 mm, dip using the jaras key dip jig ( I think that would be 3/4 inch). Anyway, I get ready to check my after touch and nothing!!! The white keys are bottoming out on the black keys front rail felt. What in the world am I doing wrong? Please help.
