When serving large dia' wire on to pull ropes, 350, 500 etc. I will strip out each conductor a minimum of 1' 1/2. After I have all conductors hooked in and around the pull rope. I take three or four of the excess strands and thread them between the conductors, (one at a time).

Using the backside of my kliens, pulling tight as I wrap, creates a nice crimping effect that realy makes the 'head' full proof. For me atleast, haven't had one fail yet. (knock on wood) [Linked Image]
