This video is going to be demonstrating
how to replace string in a piano.
I've set up a jig that has been used for
demonstration purposes, it's not an
exact piano, but we'll show the process
of how to replace a string.
There's a couple different ways, if you've got a broken string
you can leave the pins in the piano or you can take them out
but the first way I'm going to show you is,
if the pins are out of the piano
out of the pin block, and putting the
string on the pin, and then putting it
into the pin block. What we've got here is a piece of pin block with a couple of holes
drilled for tuning pins. Over here on this end, and then at the other end
I've got a hitch pin right here to wrap the the string around.
We're going to start her. I've got a regular tuning pin here
and here I have some piano wire, which
we sell both the tuning pins and the
piano wire in our online store. This tool
here is a tuning pin coil maker. This is
a good one for coiling the wire onto the
tuning pin when the pin is outside the
piano. It really doesn't work if the pin
is in the piano and you'll see why.
You'll put the tuning pin in the hole.
There's a set screw right here that the
wire is going to be pushing against as
it wraps around the tuning pin.
What you'll do is, you slide the wire
into the hole for the tuning pin
and then set the wire against the set screw and then pull the end of the
wire so that it just barely sticks out
of the end, of the side
of the tuning pin, just to slide them out
and once you've got that set there, this
is a tuning pin crank, which is
probably the best tool to use for this.
Now, what I'm going to do is, with
the crank on the end of the tuning pin,
and then I'm going to turn it. I'm going
to put about two and a half coils, okay,
so that's one, two, and about two and a
half coils on the tuning pin. Then I'm going to kind of hold the wire there
as I take the tuning pin out, take it off
of the stringing crank, and then I'll
set the wire into the hole. This is a
tuning pin punch. That's a good thing, if
you pound right on the end of the tuning
pin, doesn't always work so good, so we
use a tuning pin punch, and we'll put that, pound that tuning pin into the hole.
You won't want to go all the way because
you want some room to be able to coil
and then, of course, the bottom of the
coil should be a little bit away from
the plate, and put it in most of the way, and then what I'm going to do here then
is wrap the wrap the wire.
I'll pull it tight before I wrap the wire and I'll wrap that around
the hitch pin that I've got, or the mock
hitch pin that I've got here. Then I'll
pull enough wire out, and what I'll do is,
I'm going to cut off extra
because I want to make sure I don't run
short. So, you generally want about
three inches, and I'll show you how you
but I'm going to go more than 3 inches just to make sure I've got enough here.
So, I'll cut that off, and I've gone more than three inches, but now I'm
going to take my stainless steel rule
here, and I'm going to measure
three inches beyond, pulling the wire tight, I'm going to go three inches beyond the
tuning pin hole. So there I've got three inches. I'm just going to hold that
with my finger. I need to cut it off, and
it doesn't have to be an exact science
but if you're at least pretty close, that
will give you about three coils on the
end of the, three coils on the tuning pin,
when all is said and done
So, cut that off, then what I'm going to do is take my other tuning pin and again
I'll take the coil maker here, put the tuning pin in, and again, put it through the hole
pull the wire so that it's just barely sticking out the end
of the other side of the hole and then the
wire, up against the set screw, look, and
you want to make sure the wire goes
underneath the new coils, go underneath
and again, about two and a half turns, put
that whole pin punch
Only thing that we have to do yet here is tighten this, tighten these up.
Now, you want to make sure your
coils are nice and straight
and I can use a tuning hammer for
tightening the pins.
What I've got here is this, is a star tip
ratchet socket. It's got the star tip at
the end to fit the tuning pins. You can't
use, or not very well, you can't use a
regular ratchet socket because there's
not ones that would fit the tapered
tuning pins, but this one's designed, and
we sell these in our online store also
that fit over the ends of them on the
tuning pin. So what I'm going to do here
is just tighten these up a little bit, and as I tighten them I'm going to use
this is a coil lifter and string spacer. On one end it's got the end to
hold up the the coil, lift the coil. The
other end is a string spacer. It's got
three notches to space the three strings
of the note. So I'm going to kind of
hold those coils up as I tighten that. I'm not going to go all the way.
What you want to get, and again, you want
to make sure your, sometimes, if you're
pushing up too much on your coils the
wire is going to want to go back up
around, and then, as we get close, there's a little becket here
that you just want to push in with some pliers to make sure that the becket is
nice and tight, so tightening that until
it's mostly tight, and then I'll go back
and do the other side.
Tighten the becket on that one, and again
getting those coils nice and tight.
This is kind of a crucial thing.
So there we go.That's putting a string in
of course, where it wraps around the
hitch-pin, and put it in, and then
if because we didn't pound them in all
the way, you want to determine
how close you want to get the coils to
the plate, and then you can go
back and pound them in further, and
then once they're right
where they should be, they'd be able to fine tune them.
