The term commonly applied to the plates added between major components to facilitate
articulation . During the 14th century, this was generally accomplished with a maximum of three plates in the arm (two is better), and three in the leg. The vast majority of 14th century articulated
harnesses use only two plates, and the author's handling of two examples indicates that most harnesses probably did not allow for a full range of motion. In all probability, the motions allowed were what was required for the prevailing combat forms of the day, and the styles were in turn probably influenced by the armour technology available. Most lames were formed from very thin
iron plate, generally 18 or 20 or even 22 gage
steel . SCA lames are formed from 18 or 16 or even 14 gage steel, depending on the style of the armourer and the location to be defended. In my experience,
hammer -hardening lames helps to reduce the stress on the plate and gives it a resistance to tearing that helps a piece to endure. Additionally, most lames on the arms and the legs are rarely flat, as they are usually made in the SCA, but are rather slightly
dished or
flared . See also
