Trimming a spring shortens the length of the coiled spring wire- - - -effectively stiffening it. If you had a straight torsion bar instead of a coil made of the same piece of spring wire and cut three inches off the length, it would make the shortened piece harder to twist. Taking a coil off a spring wire wound into a circle has the same effect. Think about what you're doing before you start whittling on a spring.
