To replace a broken wire it is advantageous to make the coil on a dummy pin
and install the coil in the piano.

You start by installing the loop and cut the ends to 'four fingers'. 
Make the coil
on an extra pin, remove the coil and transfer it to the pin in the 
piano.  Lift the
coils as you tighten the pin and squeeze the becket in at or before it reaches
the "12:00" position. I use parallel pliers. Also use the pliers to 
tighten the coil
around the pin when it's up to pitch and tap the coil square. Tap the 
loop at the
hitch pin to insure seating.

When setting up the pin to receive the new coil, have the becket hole 
positioned
at 5:00; it only takes 3/4 turn to bring it to pitch. This is why 
transferring the coil
doesn't loosen the pin as much as backing the pin out three turns to make the
coil on the pin in the piano.

Get this down and you're ready for the next assignment...knot tying.

My dummy pin is cut off 1/4" below the becket hole to get into tight 
spots. It also
has a cut from the bottom up into the hole so the coil will slip off 
without having
to expand it; this is good for the treble wire but heavier bass wire 
has to have the
coil expanded because of the stiffness of the wire for the becket to 
be transferred
comfortably. Attached is a picture of my dummy pin in a stringing crank.
