sharpies 12 mm, key dip and after touch

[antares]

No, the 12 mm is a generally (by most manufacturers) agreed upon height.
It gives the pianists the 'right' touch in connection with the white keys
and it gives the piano technician ample 'space' to regulate what there is to
regulate.

The procedure for regulating key dip is in most factories like this :
First we regulate the key board (height and dip of white keys) and then the
rest of the action.
In a much later moment we regulate the key dip of the sharps by copying the
feel and movement of let off/drop of the white keys and we can check our
copy work by also checking the after touch in comparison with the after
touch of the white keys.
