One problem that can give you grief is having stresses in the metal that
will cause the cut to close on the saw. This doesn't happen all the

work on both sides of the cut to keep it from springing and grabbing the
saw you will not have this problem.

Yup, I've been burned many times by this. I just wish I had kept notes on what material
and treatments closed up and which that seemed to open.
