Yeah, this serves me right for de-lurking before rereading all of the previous
posts... :)

I just looked at your pictures, and I wonder if the way you've got the
final axles mounted (1x2 gray 2-hole beam, studs into side of 1x6
yellow 5-hole beam) is OK.  I seem to recall reading somewhere that
the parts fit that way, but that the mating caused deformation of
either the studs or the holes if left for a long time.

Does anybody else remember that passage?  Or am I just inventing
excuses for why I didn't think of this nice solution? :-)

Don't worry, someone did say that.  On page 14 of The Art of LEGO Design
(ftp://cherupakha.media.mit.edu/pub/people/fredm/artoflego.pdf), Fred Martin
admonishes us not to do that because the plastic will in fact eventually
deform.
