While I was replacing my cable sheath / cable housing I also decided it was time to get independent in terms of customizing my own cables. I cannot run this prosthetic setup and not be increasingly independent when it comes to repairs. At least, as long as the prosthetists prefer to be occasionally available and not on weekends or holidays.
So I was using the cable sheaths of Shimano.
So I have a quick lock adapter (fourth item above). That parts sits on the end of an Otto Bock cable equipped with a little nut (first item above). Now, the Shimano cable also has a nut (third above) but that nut is too large to fit into my quick lock.
So, I ground that piece down to a smaller size (second item above) and now I can run my prosthetic arm with a Shimano cable. Neat.
