I had also thought about bike cables. Bike racing is my hobby so I know a lot of people in the bike biz and maybe I’ll be able to find something.
What kind of cable did you end up using? Did you use coated cable, or just plain stainless stuff?
I found this video which seems like it does a good job of describing what how to make cable ends.
I had also thought of using something like PC-7 or JB Weld onto the ends of the cable to make cable ends then grind to shape. I suppose I could try that on some scrap cable.
Thanks for the followup!
