[pianotech] shrinking with H20 & alcohol-revisited

[David Weiss]

I have an old upright with perennial tight action centers.  Protek provides
only  temporary relief so I want to try using H2O with alcohol. 

 

Can I apply the alcohol to the hammer flanges without removing them from the
rail?  My concern is that the water/alcohol mixture will run over into onto
the hammer butt or spring punching and loosen the glue.

 

Thanks,

 

David Weiss
