Auto reversing from below - closeup
The reversing action a little closer up. A small rubber pulley on the tiny N20 motor shaft at right grips the shiny rod there to move it one way or the other. The rod is connected to the layshaft holding the two 1/2" pinions to engage the 1 1/2" gears as required.
I'm operating the microswitches here to demonstrate the action.
