Naphtha update and question

[David Ilvedson]

That's probably what's happening...make sure the hammer is hitting in the same place...use a blade to move the hammer a little and see what happens to the tone...also that you action is in the same place.  Repinning can make some change in the tone.  If the hammers are grooved pretty significantly you probably should file them whenever you starting pulling hammers and making changes...

Hi all.  A couple of days ago I asked the group about Naphtha and other liquids that might free up an old Steinway action.   The hammers were really stiff (1 to 1.5 swings) so I removed each hammer, lubricated, wagged them back and forth, and got about 5 swings out of them.  I was so proud of myself until I put the action back in the piano.  The action moved much better but two other things happened:
 
The piano had a more mellow tone--almost muffled in some areas 
About four notes have a strange small tinny sound almost like a guitar string is being plucked.  
 
Is it possible that the strings aren’t hitting exactly in the same (deep) grooves as before?  I put some travel paper under the tinny notes which helped some but not all.  
 
Still learning and looking forward to your opinions, 
 
Michelle Smith
