    Looks to me like normal D1-3 without the studs. I sure hope it is. The key point is that it looks less dinged up than my current one.

    The easiest way to do it is to sketch the lines in CAD and pick off the points using dimensions. Otherwise, brush up on your trig skills.

    To get "work hardening" you need plastic deformation. The only plastic deformation I see is at the gripper ball contact points. It looks like the neck diameter should be 7 mm. If the drawbar force is...

    My Acu-rite DRO203, Fagor 30i, semi-antique Sony Model ??, and antique Acu-rite Master MP all have tool memories. The DRO Pros units I installed at the local high school robot shop have tool memories.

    The forces from being "flung around" won't be as high as the forces from normal drawbar retention. The pull stud had to be intact to create those indents. It looks like something went wrong with the...

    I have made a few chucked keys from 4140 pre-hard over the years. I did not do anything to the existing heat treatment, and they have held up better than OEM keys IMHO.

    My Acieras use the collar method for quill depth control. They are included from the factory. At the lower stop position the collar butts against a collar that rotates with the spindle, so there's no...

    Is that some sort of tool lifter? In some ways, it looks like an owner add-on. I have an Aciera slotting head that is similar in some ways, but does not have the extra mechanism on the front.

    When my D4 shifts, I am pretty sure the brake is released and stays released. I think I have had the machine fault out due to inability to shift only twice in a dozen years. Sometimes it does take...

    The consensus on Turcite and tailstocks is, don't do it. The Turcite is too slippery and the tailstock will slip. Instead, you need to scrape the base to the ways and then shim between the base and...

    I would not worry about it as long as the quill aligns parallel with Z and the spindle trams well. My Acieras have taper pins for aligning the vertical heads. Most of the time I tram them in manually...

    Did you see the sightglass? Fill to the middle of the sightglass with ISO 68 AW oil. ISO 46 would be ok.
