<snipped very interesting description>
Just to chime in here quickly, you could use the lego small chain links
instead of tons of gears to create gear trains. Advantages: gearing ratios
are retained as in trains, backlash/chatter is reduced *significantly*, and
idler gears are unnecessary as the direction of motion of gear1 is
transfered directly to gear2.
I'm not sure that they will be useful for what you intend, but have found
them to be indispensible in removing gear backlash and chatter and for
transfering motion over distances. And you can get 108 of the buggers for
$7.50 at Pitsco-Dacta's site.
Good luck on counter and let us know how it goes!
