I *have* played around with the pinned gear idea. I used two 1x2 axle hole
bricks (stacked) with axles and two of the tiny gears, with the end of the
chain between the gears. This works quite well, and I may end up using it
to hold the chain at the chassis-end. It is a bit bulky for the forks,
however, though I'm leaning slightly toward Tim's rubberband idea,
substituting the white O-ring for a rubber band. I believe it may be small
enough, firm enough (and inconspicuous enough) for the fork-end of the chain.
Still, I'm not giving up. Maybe I'll get my Dremel out and cut a slot or
two in a brick or gently sand down a 1x1 plate-with-vertical-side-hook while
grinning fiendishly. With occasional maniacal laughter.
Thanks, gentlemen.
