THUD

[John Minor]

Sometimes there is *JUST* enough forward tip on the hammer flanges to
create this situation. You might try simply loosening the screw and
tipping the flange away from the wippen, then re-tightening the screw.

Sometimes you can even see this by sighting down the tops of the hammer
flanges and checking for ones that appear to be lower than the rest, or
leaning forward.
