A gap of 2-3 mm will give adequate clearance.

Greeetings,


                 When the keystroke of a grand piano key is complete, how far front should the jack's final position be in relationship to the knuckle?  I know it shouldnt be as far front as to have it buried in the stop felt at the end of the rep lever or too far back either.
