I wore out my set of Molex open barrel crimping pliers on the last harness I built. They are a well made product and did exactly what was claimed. The pivot became slightly “rough” for lack of a better term, when I was 200-300 crimps into using them, requiring a little more effort to open after crimping. There is definitely a learning curve and most of that is looking at the crimp after crimping and doing a “pull test”. I will definitely buy another set. Most of the instructions on the connectors that require this type of crimp prohibit soldering at all saying it’s an unreliable solution. Del, I do not doubt your abilities or experience but most of them frown on soldering.
Next time look to see if Molex makes one for slightly larger wires and terminals. Yours looks like the 63811-1000, same as I bought for use with the micro-fit terminals.
