Sticking centers again

[Roger Jolly]

Hi Dan,
       I have done dozens of these pianos with good results, 50% water 50%
rubbing alcohol. then dry with hair drier. check the wippen flanges as they
are probably slow as well. If the dealer will pay for two visits, wet both
sets of C/P and leave for 24hrs it is not quite as aggressive re shrinking,
you can reshrink and dry with drier any slow pokes the following day.
Regards Roger
