Stéphane My guess: this is a Band-aid for a geometry problem. An action with a wrong leverage need to much key dip like 11mm and if the diameter of the roller is too small with wrong spread between hammer flange pin and wip. pin The top of the jack will strike the bottom of the hammer flange at fortissimo and make a click no more click with the red felt but the problem is still there...
