Flail chain link with interlocking link configuration

A method for removing bark from a log, said method comprising:

• (A) providing a flail assembly comprising:
• (1) a flail shaft that is adapted to be rotated about a flail axis of rotation;
• (2) a flail chain comprising:
• (1) an attachment end that is attached to the flail shaft;
• (2) a free end;
• (3) a plurality of interconnected links, each of which:
• (a) comprises a plurality of adjoining link sections including a pair of oppositely disposed end link sections, each of which end link sections has an internal surface that is adapted to engage an internal surface of an end link section of an adjacent link;
• (b) includes a center of mass which defines a center point;
• (c) includes a first axis through the center point of the link and through the center of each end link section;
• (d) includes a second axis through the center point of the link and through the center of at least two link sections, which second axis is not coincident with the first axis, so that said first axis and said second axis together define a central plane through the center of each link section of the link;
• (e) includes an orthogonal plane that passes through each of the oppositely disposed end link sections and is perpendicular to the central plane;
• wherein a radius of the internal surface of each end link section that is measured in the central plane is equal to a radius of the internal surface of such end link section that is measured in the orthogonal plane;
• (B) moving the log in a processing direction that is generally perpendicular to the flail shaft axis so that rotation of the flail shaft will cause the flail chains to contact the log.
