It would be nice to see exactly how the rope is sewn through the wheels. A better camera angle at that point. You mentioned a “steel shiv” and this viewer has no idea what you are referring too.
We need a real pull test. Looks like you swapped out the traps. The trap you pulled dodnt have a bar on the pull side. The trap on the deck does with a zinc. Looks liike you pulled a light pot and swapped it for a heavy pot.
