Lift cable

There is always silver solder!

I agree the best thing is to have a spool and not fasten the cable directly to the gearbox shaft. This is what we did last year. Ignore the rust and lack of cable management.

Also, put enough cable so that there is always a wrap around the shaft or spool core. As shown above (or as I described with a hub), you're requiring extra torque at startup, and putting more stress on the mount point than if you had a wrap or two of cable adding their friction to the tug.

I hope that was a joke, or meant to be used in conjunction with another means of securing the cable.

Silver solder is an amazing way of attaching to most types of cable(not plated) you can just silver solder on a nice neat little eyelet. Or any other fastening method you might wish to use, a bolt might be a great method as well.

Silver solder allows you to "weld" two same or dissimilar metals using a lot of heat. Like brass to stainless steel.

Last year we had 2 nails running parallel to our winch shaft. Those two nails held the nylon strap down to the shaft, and they were zip-tied in place on the ends. It's the first time we ever put nails on a robot. It worked well for the short nylon strap, and I'd imagine it would work fine for non-metal cable, like parachute cord. I'll try to remember to snap a photo tonight.

Small enough cable can also fit through set screw holes in a shaft collar. Though not sure how well it would work.

FYI, "silver solder" is a term I have heard used interchangeably with "brazing".
