Those cable eye's in that second post video are nice, if I had that press, I'd probably do the same thing, and if I had enough patience and know how, I'd make them like Shield Arc's way, but in my world I do what I can do and what works. My Fransgard pto winch has 8 mm cable, and from ware and tare, the cable brake's, so I use two 3/8 cable clamps, clamp the cable in the vise, cut it with a welder, the best way IMO to cut cable with no frayed wire ends, while hot round over with hammer, make the eye and put two camps on tight, those clamps are big enough to keep the end from pulliong through the cable slide while winching.
A short story that still give's me the creeps after 35 years when I used to log with cable skidder, one day the cable broke, had to be re-cut and get the slides
back on, the boss of our small woods crew had a cable cutter, passed it to me with a sledge hammer, I said let me go get my safety glasses in my car , not far away, the other skidder driver said something about, we don't have time for that and took the sledge hammer and cable cutter, and with one wack, the boss had to take him to the eye doctor. Lessons learned, ware safety glasses when duty calls.
