<p class=MsoNormal><span style='color:#215868'>My only observations would be
that removing the action would make the job much easier and safer for the dampers.
Also you can just turn the pins out 1 turn if you make the coils on a dummy pin
and then put the pre-made coil on the tuning pin. That saves a lot of
turning of the tuning pin which will make it looser. Of course in my
situation broken strings are quite common so I do everything I can to minimize that
kind of wear since there is a great likelihood that the new string will also break.

<div>
<p class=MsoNormal>Hi List,<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I just finished my string replacement exercise and I would
like to share with you my step by step procedure. Any comments,
suggestions, do's and don't do agains will be greatly appreciated.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>The piano is a Yamaha P-2, and I chose F-57 for
replacement. The reason being it was the first string above the
overstrung area, and I wasn't about to delve in that area yet.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I used my wire cutters and nipped the string(s) as close to
the coil as possible. I then used my small screwdriver to pry the coil
off the pin, being careful not to scratch the finish of the plate. I
mic'd the string I took off, and it was size 15 wire. I mic'd the size 15
to make sure it was a match, and it was dead on.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I got my tape measure and measured from the hitch pin
to four fingers past the top pin (it was about 20''). Then I
took my size 15 reel of wire and measured out 20'', made my bend and
doubled the string. Then I cut.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I then took my tuning hammer, and backed the two pins out of
the hole approximately four turns each, making sure not to go too fast.
Then I made sure the hole of each pin was lined up and down.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I fed the string from the top. I had to manuever
it several times before I could get a hold of it from the bottom with
my stringing hook. I ran it to the hitch pin and seated it around the
pin, and then with my vise grips, clamped the pin. Then I popped the
string on the bridge pins.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Back at the top, I started with the middle pin and fed the
wire through the hole I let the wire run out the other side almost 1/4''.
As I began turning it, it did pop out once, so I had to straighten the wire
with my needle nose, and do it again. After the second coil, I used my
pliers and squeezed the coils. I was very careful not to let any wires
over lap, and to make sure my first coil was snug against the string that was
out the other side. After the third coil, I did the same procedure with
the top pin.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I had two errors thus far. First, when I went down
below to make sure the string was still around the hitch pin and bridge pin, I
discovered the string was caught up on the bridge pin on the adjacent
note! So I had to back the pin out and fix it.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>The second error was as I was cranking up the top pin, I
looked and found the string was caught in some dampers on the left and was
actually pulling them over! (Some of you may be cringing as I say
that...I sure did!) So, I backed out that pin, and fixed that situation.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>After that, I was pretty much home free. I was able to
make nice, neat coils. The top pin ended up with 3 1/2 coils, while the
middle pin had 3. In fact, the top pin is just a little bit higher than
the rest of the pins now. It is not bad, but it is sticking out just a
little farther.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I did this with the action in the piano. Figured I was
up to more of a challenge, and it actually wasn't that bad! The only
thing I did not do was really seat the string around the hitch pin. I
don't have a small brass rod with a rounded end, and I didn't want to do it
with my screwdriver.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Since the action was still in place, I wasn't able to do a
good job of stretching the string with my stretcher either.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I tuned the strings about one note sharp and that is where I
left it as I write this.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I think I remembered everything. Like I said, if any
of you have any comments or suggestions, I will take them all.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>

<p class=MsoNormal> <o:p></o:p></p>

<div>
<p class=MsoNormal>Thank you!<o:p></o:p></p>
