    I was also wondering about the chamfers. I can never get them even and it makes everything look out of square. Lovely work.

    I’ve also often wondered when you would use a horizontal over the vertical mill - doing the vee slots is a perfect example. I have the horizontal arbor bearing support for my 13 and will eventually get around to making the arbor and getting some tooling.

    How does the optical microscope work? I presume you don’t have a DRO on the Y axis.

    Default Part 2

    I had planned to make an adaptor for my Ifanger threading tool if the retractable worked. So here is the adaptor. The shaft is 4140, the end block, 1045 and the shoe, 1214. The shaft and its 12mm diameter extension were ground to size using the Hercus T and C as a cylindrical grinder. With a tenth dial indicator set up on the Y it is possible to acheive an infeed of less than 0.0001". Without the indicator it's hit and miss with the misses prevailing. The little Douglas provided a nice finish to the 1045.

    Hi BT,
    Somehow I missed your original post on this tool. Excellent work and photos, both of which are constantly improving.I especially like how you have the threading tool mounted as far forward as possible.

    Hi Bob,

    Sorry about the late reply. That tool holder is a work of art. You certainly are a master in the shed, and your photography is something that Donna Hay would be proud of. Thanks for posting AND thanks for being a continual source of inspiration.

    My apologies for the tardy response Leigh and a warm welcome to this forum. For some weird reason notification of your post only appeared yesterday in my gmail inbox???

    The small chamfers are roughly 45 degrees. I used a little protractor to position the holder in the vice at 45 degrees and then tried as best I could to hold the file flat. Seems to have worked well enough.

    I don't often use the mill in the horizontal mode but for the retractable's major vees it was essential.

    You are correct, my 13 is DRO-less. The optical micrometer was discussed in some detail a few years back - //metalworkforums.com/f65/t170823-optical-micrometers-chance-alsace/latest/post1653664#post1653664

    The thread is devoid of photos showing the device's innards so the photos below might help. The micrometers shown are metric. The silver micrometer on the mill was originally imperial and I have swapped its graduated bezel and cam with those from the better of the two metric mics.

    Getting the micrometer to focus and provide a usable image was another challenge -
