HI Julia For a light filing, yes, you raise a practical issue. There is of course a tolerance at which performance won't suffer greatly. It would be great if the fix were as simple as a let--off adjustment but in order to maintain proper regulation/ i.e. blow distance .... hammer line needs to be raised as will the drop & let-off screw. The magic line changes & the hammers now over center more as well. All the while the touch becoming lighter due to felt loss & geometry changes. It always Strikes me as such a sticky wicket. Don't you think? And then there's the scruffing scuffing hammer thing. Dale I grands, wont a let-off adjustment compensate for a slight filing. If hammers that have had medium to moderate wear are filed, why not adjust let-off? Why replace the hammers so soon? Julia Reading, PA Dale Erwin--Piano Restorations Modesto, Ca.
