    Default My new Brother Speedio toolsetter offset mount

    Hi guys,

    The spirited discussion around MiamiCNC's machine selection motivated me to finally make an offset toolsetter mount. This is what I came up with:

    img_1384.jpg

    It's steel, so it will be super-duper accurate . I happened to have a piece of 3/4" wall steel angle on hand that I used.

    Couple things that I learned while making this:

    1. When mounted at the very corner of the table, you don't have any good options for skim cutting in-situ. A big facemill can reach in X and Y, but not in Z unless you have some big extended-length facemill. Endmills can reach in Z, but not in X and Y.
    2. Yes, parallelism of the mounting surface to the table is very important. After a couple tweaks, I got it close enough so that the error between big (5/8") and little (1/8") tools is ~.0001".

    Regards.

    Mike

    Steel? It has to be Inconel! Just kidding... Aircraft grade billet aluminum works fine too. Nice job. I am sure it will serve you well.

    I thought about facing mine after mounted, but ended up using the supplied conical washer and dti to get it flat.
