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?

doi.djos., what's your opinion of this definition, then?

x1 is rotating counter-clockwise viewed from orientation x2 about rotational axis/axes (set if multiple) x3

For the actual word itself, since it seems to me that Gleki's going way off on the wrong track, here's my contribution:

(I got these words from Google translate, so don't yell at me if any are wrong.)
Chinese: lunliu
Hindi: gumai
English: rotait
Spanish: xirar
Russian: vraciat
Arabic: tonauibu

I asked Broca to run the algorithm on the above, and we got this:
(2.2040000000000002, 'gutni', [3.0, 3.0, 2.0, 0.0, 0.0, 3.0])
(2.0789999999999997, 'ramli', [2.0, 2.0, 3.0, 2.0, 3.0, 0.0])
(2.0339999999999998, 'ralni', [3.0, 0.0, 3.0, 2.0, 3.0, 0.0])
(2.0339999999999998, 'ranli', [3.0, 0.0, 3.0, 2.0, 3.0, 0.0])
(1.9769999999999999, 'glani', [3.0, 3.0, 0.0, 0.0, 2.0, 2.0])
