MINIMUM ASPECT RATIO
For a single ring size weave, the smallest AR at which the weave can be made. Can be broken down into an "absolute" minimum, in which the weave can be started, but quickly locks up as slack runs out, and a "practical" minimum, where a continuous weave can be produced.
MAXIMUM ASPECT RATIO
Some single ring size weaves will fall apart, and collapse into other weaves, if a certain aspect ratio is exceeded in their production. This A.R. is called the maximum aspect ratio.
Chainmail made with small rings. There has been much debate about the maximum ring size that must be used in a piece of chainmail for it to be considered micromaille. The ceiling ring size generally ranges from .020" (0.508mm) wire, 1/16" (1.5875mm) mandrel - .032" (0.8128mm) wire, 1/8" (3.175mm) mandrel, depending on who you talk to.
