My question had nothing to do with Hinge Action. Just your #4 in and of itself, and as it relates to the term "Swivel". Your #4 describes the Turning and Rolling Wrist Actions defined in 4-C-2 and 4-C-3. However, you say that this action is "Swivel Action". Your definition of "Swivel Action" is the same as Homer's definition of Turning and Rolling.

And the problem is....?
No problem if that's what you are saying. But it seems to me that the Swivel is a Swivel whether you purposely do it, or it gets done by the orbiting of the tension free arms. It's still a Turning and Rolling, whether a deliberate action or a result of another action.
