    Default Knife Hinges Washer Re-machining

    I am building a small cabinet that has small 170mm high doors, I am using L-23 Brusso Offset knife hinges. However the washers on the hinges are to big 1.19mm for my small cabinet making the reveal to big.

    The door is a veneer plywood core with solid wood edge lipping.

    I am looking for someone to machine the washer to a more modest 0.5mm

    Here is what the cabinet looks like:

    This is what the hinges look like

    I do not have a lathe let alone a metal lathe so have no means to reduce the washer, I happy to reimburse you if you can help.

    I am in Coburg Melbourne but I can post them to you.

    Have you got a belt sander.

    Drill a shallow hole in a piece of wood the same diameter and depth as the washer. Place the washer into the hole and sand away.
    Periodically stop and check thickness and even-ness of sanding.
    I find its easier to thing them this way that to use a lathe.

    The tenon/spigot and the washer are a single piece and cannot be separated so that will not work. I also do not have a belt sander.

    In that case its going to be an awkward job on a lathe as well

    What is the diameter of the tenon? If it's 1/4", you could try a Pen mill, with a small piece of broken/short drill stub used as the arbor, in the Drill press or hand drill, using a slow speed checking constantly the amount removed.
    Have attached an image of a Pen Mill for your reference.

    You could also superglue them both to a board, glue a strip of 1.5mm wood next to them as a file rest and go nuts with a file.

    Assuming the pin can't be removed from the flat piece, I would screw the hinge to a square piece of MDF and mount it in the 4-jaw. Centre the pin and face the washer (flange?) to the desired thickness.

    Me thinks that the pin is machined with a shoulder such as
