Wim,
How high is checking when the hammers will check?  If you can't get  
high checking, it could be a geometry problem caused by hammers that  
are too short or backchecks that are too low.  The deeper the knuckle  
has to press the rep. lever to get the hammer to check, the stronger  
the spring gets.  If the hammers have been filed more than once or  
twice, that could be your problem.  Several of the newer (1994)  
Steinways we have wouldn't check very high after only one filing just  
to the string grooves.
