B 458198, string deflections

[David Skolnik]

Well, OK. Ron says that because CA was already used (information supplied 
by Kent on the CAUT version of this topic), epoxy would not, in my words, 
"address the problem".  So, questions -

Is epoxy a no-go because it won't set up in the presence of CA?  Is it 
redundant? Does CA achieve the same hardness as epoxy?  If the rear pin is 
not migrating, and the cracks are not widening, there will be no effect 
upon tone or tuning.  Under such circumstances, the remaining question is 
whether there is some, or enough inequality in the net side bearing to 
generate the sorts of conditions Ron suggested:

In any case, Kent, can you actually provide some angle measurements for the 
side bearing?
