Now Pull out the knob, shaft and wire assembly and set aside. With a marker, mark where you want the casing to cut. We have a nice shear to cut casing. For you, a Dremal tool, hacksaw will do. Lightly clamp the casing into a bench vise and carefully cut one coil of the casing on your mark. You can score it slightly and it will break on the score also. Be careful not to kink the casing. Deburr the trimmed casing and reassemble.
