Farmerbw, you were close enough with what goes into the bottom tray. PM me your address and I will mail you one. These are indeed grinder mills, but not for coffee. They are used for salt, pepper and dry spices when cooking. They are different from the norm in that for spices the grinder has to be sealed when not dispensing, so the spices do not lose their flavor, or pull moisture from humidity and start molding. I am actually doing one at our turning club as a demo tomorrow evening, which will be the one I will mail you. They are made from spalted Pecan.

The gizmo is complete, basically a kitchen tool for someone who enjoys coffee on the run while cooking.
