1st pic - The Corona grain mill has been disassembled and cleaned out using a pastry brush to remove leftovers which have remained inside from the last usage.
2nd pic - A dab of coconut oil (for lubrication) will be placed at the locations shown by the red arrows where a ball bearing inside the piece on the right aligns to the recess on the piece in the left. When reassembled, the piece on the left, which is a shaft with a spiral "worm" onto which one of the grinding plates is mounted, rotates against the piece on the right as the handle is turned.
3rd pic - The shaft with the spiral "worm" from the other side showing the grooves on the steel grinding plate. The "worm" feeds the grain to the grinding plates. The other grinding plate is still attached to the body of the grain mill. The two grinding plates are indicated by blue arrows in the 1st pic.
