...Nineteen Laminations of Maple
Grip the
Tuning Pins...
Every piano
must have a pinblock
(also called a wrest plank)
Rawlins & Co. pianos utilize a pinblock of nineteen plies.
Material
for the plies will be cut from quar ter-sawn Canadian Rocky Mountain maple.
Each ply
must be turned so that
the maximum amount of end grain grips the tuning pin.
Two
hundred twenty three strings require an equal number of tuning pins.
The pinblock
must hold the tuning pin in place but be loose enough for the tuner to
adjust each pin during the piano tuning.
This vital part
will often be hidden from view at the time of a customer purchase.
Many makers may
be tempted to use a less costly material.
Over several
decades of use a piano must be tuned many times. Only quality material
will stand up to this test. Inferior material will certainly fail.
