[CAUT] tight balancier

[Willem Blees]

At the NCRC this past weekend, someone mentioned that a tight 
balancier will cause a hammer to bobble. My question is, does anyone 
have a gram resistance measurement for this? 

I'm trying to visualize it. If the balancier is tight, then the spring 
will need to be tight, which could cause the hammer to bobble. But it 
is too loose, the spring would need to be loose, which could cause it 
not to hold the hammer. 

I have several pianos with bobbling hammers, especially in the 2nd and 
3rd octave. Before doing anything, I want to know what to do. 

Thanks for the input
