Articulation

This discusses articulation as it relates to armour. Articulation describes the mechanical interaction between plates that compose a piece of armour. Pieces that are attached loosely via rivets, allowing a degree of rotation or movement between plates, is generally the goal of articulation.

Articulation is a critical skill for any armourer.

Methods

A variety of articulation methods exist.

• Shell Articulation: This is the most common method. It is used to attach lames to other pieces. The articulation in arm harnesses and leg harnesses is achieved via shell articulation. In general, two rivets are placed through both pieces, sharing a common axis, thereby allowing both pieces a degree of rotation.
• Leather Articulation: Sometimes articulation needs are best served with a flexible connector. Leather is simply riveted between to pieces, attaching them together, but allowing the leather to bend if necessary.
• Sliding Articulation: Similar to shell articulation, sliding articulation involves a slot instead of hole for each rivet used. The two attached pieces may then slide as required, compressing or expanding the shape. Sometimes combined with shell articulation.
