I suppose I DO have a bit of a fixation...
I have been looking out for a true "wind-up" motor, but don't have one yet. My
solution is to have one gear in the drive train that slides out of position to
disengage the drive from the clockwork and allow for the pull-backs to be wound
up - they are connected so that winding one also winds the other - then I slide
the gear back into place, engaging the drive train. Not the prettiest solution,
but the most economical for now.
