Also, put a dot (union a sphere onto your gears) to mark the rotational
position.

First, this gives a much nicer visual effect, because it gives your eye
something to lock onto and make better sense of the rotation.

Second, if you're going to make a cyclic animation, you need to have all of the
dots line up with where they started.

For long gear trains, that might be a LOT of frames.
You can likely put multiple dots on the gears so that you can use a fraction of
the frames to get a good cyclic result.

I can tell you now:  That would make a valuable macro.
