Karen,
First, I am deeply saddened at upsetting Audrey and wish I had not done so. I would ask you not further contribute, we are friends and we need to allow each other our peace.
In answer to your question… And I would hope Bernhard will correct me here if I err…
Audrey,
It appears as if you might be upset and that was not my intent and I am sure it was not Bernhard’s.
And Audrey, when we catch you chasing your kids around with a bucket, we will know you have taken the traditional way too far!!
Audrey, pg. 10 of Bernhard’s article should be of interest to you…
“If the load of a string is near up to breaking limit, the
string will be continous elongatied by the constant
overload so it has to be compensated by tuning
again. During the time the string gets more and
more thinner and weaker until it breaks. This can
also happen after one year or later. One shouldn‘t
forget that the stress on the string is not spreaded
equal because of the friction at the bridge pins. The
bigger the bend is on the bridge pin the bigger is the
friction, and the bigger must be the reserver on the
wire.”It all makes sense.
I agree the area has to be cleaned first before anything is put on. The Renaissance Wax prevents this phenomena, it does not cure it.
Sorry Carl, I will continue to scrub with fine steel wool and scrub pads using copious amounts of mineral spirits, but no scraping!
Audrey,
I am really guessing…. but in my experiments I have noted that as the string stretches under tension, it decreases in guage. It gets thinner….so the mass per length actually decreases. The Mass per Length is part of the frequency, (Tone) equation…. So then you wind up compensating with tension….
Dawn, you raise a very good point. If sound integrity is not compromised and the instrument is structurally sound, I believe a crack might even lend some character and not be out of place on an instrument that old. I am concerned that they will take the instrument to a shop that will not appreciate the instrument for what it is and they will wind up with a total loss. While we know they could never sell it for it’s replacement value, it certainly would be that much to replace it.
I would look for a music shop in your area that handles Violins, Cellos etc. Ask them for a good luthier. Stay away from guitar stores which may be a problem in Nashville. Or contact someone like Lyon and Heally.
INSIST UPON REFERENCES AND SEEING EXAMPLES OF THEIR WORK!
Repairing a concert harp is something that will take special skills. I work on far simple folk harps and experiment with different configurations.
