Naphtha update and question

Michele,

        It is never a good idea to correct a hammer's travel that is grooved. 
Grooved, the hammer will not "obey" its correction. The hammer will want to 
"find" and  fall into the old string groove, and can even stick there, not to 
mention the stress it can cause on parts pieces because now its travel has been 
corredcted at its outset and when it gets to the string it wants to strike in 
a new place but fails to, and the old grooves cause the hammer to bounce to 
its old position causing unnecessary twisting or deflection to other parts 
offseting pins or whatver depending upon how far it was "corredcted". 

       A hammer should be first, degrooved (carded or filed) before it is 
realigned and travelled and this is part of regulating. 

Make sense?  If not, ask me questions.
