CA Glue for pin blocks

[Jonathan Best]

Thank you Fenton and everyone else for some great thinking!  This  
particular piano that I'm referencing has pins that are marginal in  
my opinion whereas another tuner feels that they are fine.  so from  
the feedback that I am hearing it looks like CA is the way to go and  
I don't have to worry about wrecking a recoverable pin block like I  
would if I used Pin-Tite.  This list is great!  I think I'll stay a  
while.

Thanks again.
