MSM wrist 0.2 [prototype]
Posted on October 29, 2009
Our first prototype (also check the road map) had to be wiggle free, be rock sturdy and be fast to produce.
Our second prototype now is the type of lock that I always wanted - sleek, rock solid and superbly functional.
Functions:
- Lift as much weight as my silicon liner can transmit on the arm.
- No wiggle.
- Switch any rotational position and switch it fast

Benefits:
- Switch any rotational position and switch it fast.
- Stable.
Remaining issues [October 2009]:
- Internal part positioning and relative sizing to maximize robustness not yet fully optimized.
- Lock consists in a flat cover (see photo) that contains a patterned edge but a bigger handle would be more useful.

Benefits:
- Switch any rotational position and switch it fast.
- Stable.
- Comfortable grip mechanism.
Remaining issues:
- Internal part positioning and relative sizing to maximize robustness not yet fully optimized.
- Grip mechanism minimally oversized and so it can rip against cable unless it is very smooth (I smoothed it for time being).
Current status [December 2009]:
- The product works absolutely flawlessly. It is what I want it to be, functionally.
- There are design and robustness issues to be improved to allow for better wear and tear performance and to make it more robust to extreme strain. So the prototype is currently subject to revision 2.
