Increase of terminal device loading to a cable load of ~ 110N (~12 kg) has caused some issues. The cable housing so far contained a metal spiral and a silicone tube. These would rub on each other, and due to getting pressed hard the metal spiral would elongate and deform. Also, I wanted better control over pronation and supination.
Several attempts to remedy the situation have been undertaken.
Results are both theoretical and practical. They are shown below:
Already two days into wearing this setup we see clear degloving of the steel threaded PVC housing:
After these failures in conventional cable design I decided to redesign the cable setup from ground up.
