    A friend who runs a restaurant has several pepper mills in which the ceramic grind cone has failed. I have not been able to identify either a replacement for the ceramic grinder pieces nor a whole grinder mechanism that will fit the existing body. Does anyone recognize this unit and know of a source for parts?

    Here are some of the dimensions: The rod is exactly 10 inches long and the non-threaded portion has a 3/16 inch square cross section. The maximum outer diameter of the larger ceramic cone is about 0.95 inch including an outer lip about 0.12 inch wide and the maximum outer diameter of the smaller cone is 0.75 inch. Thanks for any help. PepperMilljpg.jpg

    Check craft supply there kit may not be exact to just replace the broken part but you may be able to replace the whole mechanism. You can look at the instructions on there website to get the specs to measure the holes to see if it fits without modification.

    What's the diameter of the hole bored in the lower portion of the mill? It certainly looks as though a standard "made in USA deluxe" mechanism that most places sell would fit (most of the parts look very familiar). If the hole is too small it wouldn't be too bad to drill it out a little bit so that the common mechanism would fit. If it's already too big that's a harder problem.

    I would think a wood grinder would not even be in a restaurant during these Covid times. How do they sterilize those?

    Roger, the first 0.25 inch of the bottom is bored to 1.5 inches. Then the bore steps down to 1.25 inches to accommodate a 1.25 inch OD by 0.97 ID by 0.6 inch L nylon collar that provides lateral support for the outer ceramic grinder cone.

    Ah, so that's probably too big for the typical mechanism that wants a 1-1/16" hole, nothing for the screws to bite into. You could turn a donut shaped adapter, perhaps out of 3/16 or quarter inch BB plywood that would set into the hole and give you a surface to screw the mechanism to. You might have to drill the recess slightly deeper to allow it to fit. An adapter that would set inside the inner hole would avoid that step but require more precise sizing.

    All the mechanisms I've used have all wanted 1-1/16" center bore so I can't help with suggesting a different kit.

    It would be easier to plug the hole with a dowel and drill it out to the required size.

    I was hoping to save myself a bit of work if this was a commonly available grinder mechanism. Thanks

    That is what I was going to suggest. It's not that difficult to turn a stepped plug and then drill the appropriate size holes for a new mechanism.
