stretching wire

[Dean May]

Heat will reverse the work hardening from cold forming, which will make the
wire weaker. It's why you'll see stickers on the frames of semi tractors
that say "No heat or welding on this rail."

Would it be helpful to heat wire before stringing to cause it to be more
pliable and create the bends faster.  Lights and sun can cause the string to
move quickly.
