splicing strings

[John Pasterczyk]

Don't let the knot be a stumbling block to the
exams...

Truth be told, on the stringing portion...

I forgot to pass my new unison strings through the
agraffe, and went back and redid that portion
(nerves)...thus leaving myself no time (or very
little) for tying a knot on the third string.  On the
knot I put the new string through the wrong hole on
the agraffe and didn't get to tighten (but I think I
did pretty good with only 30 secs. to complete this
portion)

Anyway...I got 0 points for my knot (or lack thereof),
and still passed the exam...

If this is all that is holding you back...

Go for it.

I have yet to master the KNOT...and is probably the
major stumbling block for me, in trying the technical
exam for RPT. Any ideas ??

pix. One BIG warning: if the break is between agraffe
and tuning pin,
make sure you pass the string through the agraffe
*before* forming the loop
in that section of string!

Hi Matthew,

Here is one way to do a splice. I am sure there are at
least 6 or 7 other
methods that will work also!

splice1.jpg
Using round nose pliers, make a 270 degree bend in one
wire. Then make
another 270 degree bend in the wire you are using to
make the splice with.

Connect the two pieces of wire as shown.

As you pull on the ends of the wires, the knot will
begin to form.

Cut the ends of the wires so they are not sticking out
more than
1/4". 1/8" is better! Just don't cut the ends so close
that the knot
could slip.

Now that the knot is formed and pulling tight, you are
ready to put the
string in the piano. Attach the loop to the hitch pin,
thread it through
the bridge pins, up to the upper bridge pin (or
agraffe), up to the tuning
pin. Measure the length you need to make 3 turns
around the tuning pin,
and install the string. As you increase tension on the
string, the knot
will pull tighter and tighter. Voila!

Hope this is helpful!
