shortening interconnects

Anyone have any skills at making ic's . I have an oppurtunity to purchase a 4 meter pair of shunyata reseach constellation series. I would like to make three pair of shorter cables out of the 4 meter pair . I have noticed on my kimber hero ic;s a set screw that appears to hold the connector to the cable . Any thoughts on the skill needed to do this ? or tips ? thanks ! Or i could possibly send them off to be done professionally if cost would warrant this .
