Perhaps, a long way down the road to xsyon, we could a new craft, Metal Scrapping, which focuses on making metal Armour based on items from junkpiles.

New Items needed for this would be:
Tools: Mandrel (a metal rod with a handle which turns freely in a support. used for coiling wire)

Materials:
Wires Of Various Gauge and Metal.
Anvil

Simple Items:
A Spring is made by coiling wire using the mandrel.

Open Rings are made by cutting the metal spring along a straight line with shears.

Rings are linked together to make scraps of chain fabric.

Scraps of chain fabric are linked together to make sheets of chain fabric.

Beer Tabs can be cut and linked into the chain fabric to make Beer Tab Scale Fabric

Bottle Caps or Coins can be punched and cut, then linked into the chain fabric to make BottleCap Scale Fabric and Penny/Quarter Scale Fabric respectively.

Chain Fabric and/or Scale Is used to Craft ChainMaille shirts, chainmaille pants, chainmaille mittens, chainmail socks and chainmaille hoods.

Plate Armour is made from Metal Sheets and Metal Plates primarily, as well as leather and cloth parts. It would require a hammer and anvil at the very least. Anvils should be a very rare find. Plate Armour would include items for most body parts

There could be higher level sets of Armour which use combinations of plates and chain fabric to create.

Wire can also be wound into rope, but only by a master craftsman.
