Pinblock

Every piano must have a pinblock (also called a wrest plank) Schwetchen pianos utilize a pinblock of nineteen plies.

Material for the plies will be cut from quarter-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.
