I am a sailor-type, and you might want to look into the various ways of using sailboat rigging.... Easiest to use would be the Nicopress, which can be done really cheaply and quickly. I'd bet that there is a sailing/rigging outfit somewhere in Hotlanta.. If not, you could probably make it work with some big vice-grips, or even a bench-vise? .... or just sweet talk those sailorboys into letting you borrow the tool....!
Awesomeness in those rides, for sure!
