Interesting post on HSM by Dorn:
Using annealed stainless steel wire (aka safety wire) that is not springy in this state, it can be work-hardened by stretching. Once work-hardened, it can be wound into a spring.
I also use a "Drawing" technique when I want smaller wire for a model or repair application. I open my vise about 4 or 5 inches and then wrap the wire around the jaws ( 2-3 wraps ). Now I open the jaws more and draw the wire down to a smaller size with
out having the use my legs or arms, only the vise leadscrew.
Never tried it... but it's something to keep in mind for when that someday comes along.
