Here, the control lever has been moved upwards, raising all six of the pawls:
Same positions, but with the chain drum in place, shows where the pawls will push on the drum:
Working well! Next step will be to make the bushings for the inside of the chain drums - the center hole in them is larger than the shaft to leave room for them. The bushings will allow the drums to spin freely when the pawls are retracted.
