[pianotech] Key Bushing Job

[Paul T Williams]

Pianotek!

BTW.. I think the 'black' gunk on the bushings is probably from earlier 
graphite, or just key-pin oxidation rubbing off on the cloth.  I'm still 
not convinced on the VS-profelt yet.  I tried some on dented wippen 
cushions but nothing more than just putting on some water-alcohol solution 
or just rubbing alch....If you dribble some of either on the key bushings, 
be sure to put in some Spurlock cauls to set them. It'll work.

What is that VS made of.. Is it just a "hype" product??

Thanks Barbara and all,
 
I'm going to give it a try on some lower quality uprights in the piano 
store.  Now

 where do you buy the vs profelt?  I can't find it?
 
Thanks again

Steven,
 
Take a look on the CAUT archives--especially the posts written by Fred 
Sturm--in the past couple of months.

Hello,
 
Just left a customers piano that would benefit from new key bushings. 
However, on the way to lunch I thought the ones i looked at did not appear 
to be overly worn yet they are loose and make some side to side noise.  My 
question is:  is there anyway to swell the bushing and use an appropriate 
sized caul instead of completely rebushing the entire set?  Just wondering 
out loud so please don't beat me up. :)
 
Also the front rail bushings have black lines where the key rides on the 
pin.  What is the black stuff?
 
Thanks,
