I'm re-using a old BT60 nose cone that has most of the base cut off including the molded in loop for the shock cord, it's just part of the shoulder left and a hollow base. I'm wondering how to connect a shock cord. The only thing I've come up with is to make a disk to glue in as a bulkhead right in front of the shoulder and connect a loop of wire or kevlar to that. I did this for my Big Daddy to eliminate the suspicious angle at one side of the original nose cone shoulder.
