Hi Eric,
I actually intended that the inherent backlash in the z16s was
exploited to turn them in a little after the positioning. You could
replace my z16s with two z24s and a z8, making one of the z24s a
clutch gear so you could turn them against each other. Either way -
you can do the positioning by just turning one of the gears - which
saves the hassle which bryce described.

A very interesting trick, Danny. Here is my implementation of your no-backlash
transmission:
Of course there is a trade-off between backlash and friction, but your design
allows easy trimming.
