I have the two terminating ends attach on the back of the motor arm. A spring will attach to the protruding bolt head. Stringing should be much simpler and less nerve racking. We will only have to do one loop between a pair of bolts.
*Better access to the termination of the strings
*I enlarged the clearance for the pulley. (You can't see that from this view.)
*I decreased from 1.5 loops to 1 loops. (Less stringing. Less confusion.)
*This setup is perfectly proportional.
*Double herringbone gears for slightly better registration. (I never had a problem with the single herringbone gears but these will be better.)
