Abstract
A wrestplank includes first and second outer working plies, and at least seven median working plies stacked therebetween. Each working ply defines a direction of grain. The working plies collectively define a tuning pin hole configured to securely receive a tuning pin. The directions of grain of the outer working plies are oriented substantially parallel with respect to a longitudinal axis defined by the wrestplank. The directions of grain of two of the median working plies are oriented at an angle of between about 60° and about 75° with respect to the longitudinal axis. The directions of grain of two of the median working plies are oriented substantially perpendicular to the longitudinal axis. Furthermore, the directions of grain of two of the working plies are oriented at an angle of between about 105° and about 120° with respect to the longitudinal axis.
