Nolan,
Why do you feel the need to correct me on every reply I send?
The fact of the matter is that anytime you apply heat to springs or modify them
in any way it is impossible to predict the properties afterwards to
any degree of surety. Cutting used springs is even less accurate because with
time and wear, springs will ALWAYS vary in the tensile strength they
were designed for.
Therefore, I STAND BY MY ORIGINAL STATEMENT! The math is only as good as the
metal's properties before and after the modification. You can't know
the properties of used springs any more than you can predict the affect that
the heat used in modifying them.
