[Elecraft] DIY Hard-drawn copper wire

Copper is ductile, not elastic. So pulling it will cause it to stretch but
when it breaks it does not return to its original length releasing a lot of
energy. It will simply separate at the point of failure, as others noted. 

Even so, I am careful any time I'm applying a lot of pressure to anything.
Murphy reigns supreme over mere mortal Hams.

Those are what I was thinking.   Be sure to be safely inside the car and 
be willing to damage the car.

p.s. I think it's cheaper and better to just purchase harddrawn copper or
copperweld wire.  YMMV
