You mean here? He seems to be advocating the usage of two words, one for "turning" and one for "rotating", which I advocate. You seem to be discussing the use of two different words for "rotating", which I don't. Later, in your latest email, you seem to mention saving the second word for now, which is a good idea.

In general, I don't care what gismu is chosen, as long as one is. However, I'm still afraid you've defined the wrong word. That is, we need counterclockwise, as these two definitions are equivalent:

> x1 is spinning about axis x2 such that if your right hand's fingers are curling in the direction of rotation, your thumb would be pointing in direction x3 (along the x2 axis).

from the BPFK page, and

> x1 is spinning counter-clockwise about axis x2 seen from side/perspective x3.

Also, if we're actually making a new word, I'd like to mention something. I generally find the axis usage clunky and rarely necessary, as it is often easier to give a more specific direction than an axis, in English or Lojban alike. Thus, the axis spot is mainly useful wrapped in {lo SE broda ku}. Shouldn't the x3 spot be the axis, then?
