This is awesome! I have that grinder, but haven't had this issue (yet...). My only issue is that the lowest grind setting isn't quite fine enough for some beans

This is awesome! I have that grinder, but haven't had this issue (yet...). My only issue is that the lowest grind setting isn't quite fine enough for some beans, but with your pictures I think I can actually see where to shove a tiny shim to make that work better too. I'd always intended to do that but hadn't ever gotten around to it.
