1939 Steinway wippens

[Erwinspiano at aol.com]

HI JD
  May I slightly remonstrate?
   On American Steinway parts with the green scum syndrome,  replacing the 
bushing & the pin will only result in a waste of time.   The culprit is in the 
wood. Having done this on my own piano years ago I first  removed all the 
bushings & soaked the parts in perchorlethylene as an  effort to remove or dislodge 
the chemical culprit from the wood  itself, & then I rebushed & pinned.  A 
year later green  slim & friction  was back with a vengence.  
  It's like disturbing it just made it angry. Fortunately all that  expensive 
white wood you refer to on new wippens comes with new bushings  and pinning 
making it worth while.grin

I  can't understand why anyone should suggest fitting new whippens. It 
sounds  to me as if you just need to re-centre or at the very most 
re-bush and  re-centre, since if by "vertigris" you mean verdigris, 
then you  are talking of oxidation round the centre pins that has made 
them  stiff.  The cost of a set of new wippens will be very high, they  
probably won't be an exact match, and there is nothing to be gained 
by  replacing them except the nice white-looking wood that will never 
be seen  anyway.
