hi pressure pressure bar

[Tvak@AOL.COM]

Tuned a Kimball console yesterday and broke a string.  A trichord unison at 
E3/F3 broke at the becket, which surprised me since the piano was not that 
flat.  And then I found out why it broke.  The pressure bar is extremely 
tight and creates way too much friction.  I judge this on the fact that it 
was extremely difficult just to remove the broken string.  I had to use a 
pliers.  And the needlenose pliers I tried first didn't do the trick;  I had 
to get the big pliers out of the tool case and pull as hard as I could to get 
it out of there, and it went millimeter by millimeter by tug by tug.  (My 
wrist is still sore today.)  I didn't replace the string because it goes 
under the bass strings and I didn't have the tool with me (that tube thing 
from APSCO, whatever it's called) to insert the new string in place.  (All in 
all, this was my lucky day.)

So I'm going back next week.  I'm worried that I won't be able to get the new 
string under the pressure bar.  I've been told NEVER loosen those screws on 
the pressure bar, but what if I can't get the string in there?  What will 
happen if I loosen that one little screw? And in fact there is one right 
there between E3 and F3.  I think that little bugger is the problem here.  

I would imagine that loosening the pressure bar a bit would put that register 
out of tune. OK, I can retune it.   Any other dangers here?  Will the piano 
bench fall apart or the logo decal come off?  

Seriously, I'd appreciate any thoughts on the subject.  It would be pretty 
embarrassing if I can't get a new string in there.
