What Paul has kindly illustrated is what I referred earlier to the 'Weave Method'. I've been using it for years without failure. I now purchase plastic coated steel leader from a fishing supply store. I buy the A3 couplers from the fihsing supply store for 2-56 cabling systems as my crimpers, and A4s for my 4-40 systems. I use to cut my own tubing to use as crimpers, though I can buy the A3 & A4 crimps for making up steel leaders that its not worth my time anymore to make the crimpers manually. Then I purchase rigging couplers only from the LHS to make up my Pull-Pull cabling systems.
