I've managed to acquire a motor for my new Crankandstein 3D and the plan is to attach a shaft directly to the mill, rather than use pulley's etc. I've read a few comments on various threads that talk about the likely damage to the mill if rocks or stones or whatever is pulled through the mill. Given my motor has huge torque, whatever is put in the hopper will get sucked through the mill.
My question is how often have people seen rocks or anything else come through in their grain and where did you buy it from? I would have thought the grain is a food grade product and as such items like rocks (or anything else) would be a one in a million event and therefore pretty low risk.
