replacing plain wire

Wim,
as a matter of course, I try to find 'several' indicators before doing major
work. Denis Brassard ( Banff Centre for the Arts ), a careful, clever and
respected technician, really emphasized this principle to me.

As well, even after almost 20 years in the trade, I am still some what of a
"chicken" and like to "choose my fights" carefully. :>)

For example, our recital 'D' was 10 years old when I began here, and
entirely original.

I was aware this piano was "overdue" for stringing according to general
recommendations, but began to look for specific indicators. It didn't take
long:

1.) False beats that couldn't be eliminated through (gentle) string-seating
or advancing "fresh" wire into the speaking length.

2.) Poor rendering in the treble sections.

3.) Spontaneous string breakage, at the capo. (typical point of elongation)

I capitalized on the "visual aspect" of the latter by splicing rather than
replacing strings (I favor splicing over replacing, unless the stringing as
a whole is fairly new).

It was then a simple matter to demonstrate false beats, show a segment of
broken string, and point out several splices, to the 'peace of mind' of our
Dean (and myself), that re-stringing was overdue.

BTW, the false beats were actually caused by loose bridge-pins, barely
"finger-tight," from F#4 (gauge change) to C8.

Although I believe you can and will discern a difference between new and
older string Wim, the greatest benefits seem to come from servicing all
bearing and termination points at the time of a re-stringing.

best regards,

        As you increase the tension and approach the breaking point,  the
weakest
        point of the wire will begin to fail.  As it does, that section
becomes
        thinner.   If you stop at this point, you now have a wire with one
of the
        wildest false beats you ever heard.




    So if I understand it right, the time to restring should be when a piano
starts having more than its normal share of wild strings. (wild strings that
cannot be corrected at the bridge or other termination points).

    So how many of you have restrung a piano with this parameter?
