Can Lowes post instructions on how to properly use this tool and the ferrules thy sell.

I agree a video would help. I looked on line on how to properly use a ferrule and stop. There are a few videos ( not of this swaging tool) of how to properly crimp a ferrule. Most are using very expensive crimping/swaging (professional) tools. My particular use was to hang a mirror on a wall using 1/16 th inch wire rope. I ended up smashing the stop. I would prefer to also crimp the ferrule for added safety.
