[CAUT] breaking strings, Kawai KG-2A (1997)

[Jim Busby]

David, others,

 

Yes, I guess that's what I need to do (Restring). I guess it'll keep the
students busy... Ed's right. I should just consider it job security!

 

Thanks for the feedback.

Jim:

 

Restringing the top two sections of pianos is a common thing for me.
After 3 - 4 years they just get that way.  After restringing the capo
sections they calm down for a while and then in a few years it's time to
do the whole piano.  Kawai's might be more prone to that than some, but
our practice room pianos now are all Steinways and they do the same
thing.  It really is string fatigue.  They pretty much all break at the
capo bar.

List,

 

We have four KG-2As that now break strings regularly (weekly) in octaves
5-7. The bass is also becoming "thumpy". Granted, they are very heavily
used (Up to 17 hours a day), but we try to keep them voiced and
regulated so I don't believe maintenance is the issue; I think the
strings are simply fatigued. (I can break strings myself with 20 - 30
good solid blows.) I tried decreasing the blow to give a bit less power
hoping that it would diminish the breakage, and that helps somewhat, but
I don't like to sabotage piano performance just so I can work less...
BTW, the strings break mainly at the v-bar.

 

I will be restringing these pianos next month (I've HAD IT with them...)
so does anyone have any advice concerning the scaling, etc.? I will be
dressing the V-bar and doing all the usual prepping. This is a high
tension scale and I'd love to redesign it but don't want to put that
kind of time and money into these...

 

Any helps out there???

 

Thanks.
