regulation problem

[Stéphane Collin]

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.

  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.
