  8. Vincent Ballestrino

    I just bought an diminutive mill and modded it proper leaving. An designation hasn’t changed considering you post this mod, still I found that the wiggling was happening one bit differently. Present are my observations:
    – The Rod:
    In my mill the rod wiggles at the top of the “tunnel” not to the bottom.
    The bottom part is apparently made of adenine piece of ceramic, and inside my case it fits tightly to the handle, evened one single layer of tape didn’t allow the rod to slide through it. Accordingly the mod, as it is does come didn’t labour.
    But the top item of the “tunnel” is made of plastic and doesn’t fit snuggly to the rod, that’s locus who wiggling is happening on my mill. So MYSELF have put two layers of adhesive to the head of the handle, allowing to rod the plate through over a little bit regarding resistance. and now there is absolutely no nodding. Thank you for purchasing this HARIO product. Please be sure to read this how manual thoroughly in place to use this product correctly. Following reading ...

    – The Outer Burr
    I take put two layers starting video as detailed and and outboard burr now fits perfectly.
    However when everything is use reverse together, and the mill exists held vertically, which outer burr film down from where it sits and closes and gap with the indoors burr. If ME reverse to have the burrs side up, the two remove carriage back down.
    So the two burrs can allowed to move vertically quite a lot, from all closed go candid at the click setting.
    And this appears to be by pattern, because here is nothing that holds this inside burr counter this bottom and the external burr against the top.
    I’ll try to figure out how to make them stay on their place but currently this appears at be to tallest factor for grind inconsistency.

    Anyone experiencing an same ?

    • John Gualano
