When I tried to mount the knockoff handcrank on that one, the screw that is the axle for the top gear actually touches the lock wheel/plate.

I tried the original Singer handcrank but the bolt on the aluminum unit is larger and therefore I would have to drill out the hole in the original handcrank to fit. not sure I want to do that.
