Many people who’ve spent time attaching boats to moorings have probably heard of line threading mechanisms like the Swiftie and EasyMoor. I’ve noticed several posts on the forums here where people have said they’d like to use Trident to retrieve heavy items from the sea floor, so I thought I’d try adapting this concept to work as a Trident payload. Using our laser cutter, I made a polypropylene part with holes to attach to the 50mm-spaced inserts on the bottom of the Trident, and I bent some piano wire in a shape that would both work as the threading gate as well as create spring pressure so the gate would close itself after being threaded.
In the future, I’d like to make a design with a wider gate and a protrusion beyond the gate so things don’t slip off while you’re pushing against them. In the meantime, I thought I’d attach some images and videos of my first attempt to get people’s minds turning on the concept.
I’ll aim to post CAD files for the parts once I get everything refined.
Let me know what you think!
