Baldwin termination bars

[fssturm@unm.edu]

Hi Roger,
   Thanks for the input. Problem is, this seems to apply to the entire unit, not to 
the individual terminations. My colleague says he tried any number of things 
with individual unisons, from a wide range of voicing techniques (filing, mating, 
needling here and there, etc.), To folling with bridge pins, to shifting strings back 
and forth (on the termination and backing to and fro on adjacent tuning pins), to 
lowering tension and filing the actual termination points. All to no avail. 
   He says the other termination section has no problem noises (or at least just 
the usual sort). That the noise seems definitely to come from the actual 
termination unit (moving ear around and listening to volume). And the fact that 
tightening screws silenced the problem by over 50% (his description) seems to 
clinch it - that either there is a noise produced between plate and termination 
unit, or within the unit itself. At least that's my conclusion, without having ever 
seen the instrument. 
   I told him I thought he'd just need to bite the bullet, pull the strings, pull the unit, 
and see what he saw.  He feels sqeamish about it, lacking the old devil may 
care spirit, and wondering what happens if he gets it apart and doesn't find 
anything. How can he charge for his time without assurance  it will be 
productive. The age old problem. (My own solution is to eat the time and call it 
educational expense). 
   So anyway, I thought I'd throw the problem before this forum of wise, 
experienced, skilled pandits in hopes that someone will say, "Hey, I had just that 
same problem, and this is how I solved it," so as to ease my poor colleague's 
nerves.
Regards,
Fred Sturm
