Chain is crazy easy to make. a rod with the O.D. that corresponds to the I.D. of the chain you want to make, with a hole across one end, and a electric drill, and a hacksaw are all you need. Stick the rod in the drill with the hole on the exposed end, stick the end of the wire you intend to make the chain links from through the hole and pull the trigger. After you have wound the wire on the rod, cut it lengthwise, and dump off a pile of links. hook them all together, and pinch them with some small pliers and you have hand made chain. Silver, brass, or copper, can be hammered with a rawhide hammer to work harden it after it is pinched closed.
