Yeah, I devised that. That could be corrected using aditional layers with an angular offset, so you can stop at half, or less, steps of the main ratchet. Another solution is a mechanism based on the Vernier, that can stop in even less fractions of a turn. We could make this by making the stationary part and the movable part with a different quantity of stoppers, and then a second layer with a radial symmetry of 180 degrees to assure at least 2 point of contact.
Well, it is just an idea towards a less vitamined Simpson.
