The piano is a 1928 Chickering Model M, Scale 141 (small concert size). The
problem is this:

 

As the key is depressed slowly-pianissimo-for the first millimeter or so the
key and hammer move smoothly. Then something starts binding, it feels like
something in the action is dragging, holding the key and action back. After
forcing the key down another three or four millimeters action becomes free
and everything operates normally. On a medium to hard blow there is good
power and the problem is hardly noticeable but at pianissimo the action will
hardly play.

 

What is the problem and what caused it?
