I normally just hand straighten the music wire (guitar strings or rolls
from Precision Brand) I use. It is also easier to bring coiled wire to
contests. However, it is possible to mechanically straighten rolled
music wire at home. One just needs to take a length (a whole guitar
string is a good length) and pull on it until the wire breaks. One needs
to fasten the ends well so that the wire does not pull loose from the
ends. For 0.013" wire, it will take at least 50 pounds of force to break
the wire (if less, the music wire does not meet the tensile strength
specifications). I sometimes put a very small nick (with a file) in the
wire (just like a scratch) an inch or two from an end so that the wire
will break at the nick (so as to get the longest straight length and not
two shorter pieces). This method works by stretching the wire to a
stress level well past the elastic limit and resetting the wire's shape
(just like coiling straight wire resets the wire into a coiled shape).
If the wire breaks too soon, say at a defect or at the ends, the wire
will not be stressed well past the elastic limit and the wire will not
turn out very straight.
If I recall correctly, I think Ray Harlan first told me about this
method.
