Possibly just use solder on clevices?
I don't know how scale you are looking to be.
On my 1/3 pup I didn't actually use cable, I just soldered clevices on the ends of piano wire.. it is SUPER rigid when put together. I also use the trick of special holding foam racks that hold both left and right wings together when off the plane,
... Its a great way to save hassle if the wings are split from the fuse.
