    @ Tallen, good chance your welder is in “synergic mode” where the user adjusts one knob and the machine decides the other settings. The main advantage (old timey) was for somebody to set the machine...

    I’m not going to put my name on the inspection report but I just tried that with my starrett 120A 9” caliper & could tell a difference (hard to resolve it correctly though). I had a lot of trouble...

    You’ll get it. In the meantime attached below is lost motion in a machine tool from Caterpillar U.

    Since when did “old school” not include fundamentals (& maybe some intermediate stuff tossed in)?

    I can’t imagine the owners were worried about somebody stealing their repair type business, more likely is the worry of a customer seeing a video & questioning about how much time they were charged...

    I believe he was saying the tool is always advanced “toward” the new value. So that means when setting you touch off on the 0.625” bore and “move plus” in the same axis direction to enlarge the bore....

    I think both the optical and the end measuring system went on more or less the same way. There were 2 spot faced areas with tapped holes on the knee you could clamp most anything to.

    They also had...

    In post #1 last image, if that’s the view I’d get with jewelers glasses on you can divide inside of 5’, one minute would be a stretch though. I think it’s a parallax resistant feature. The one in...

    Yes, they’re for end measuring rods reading in tenths. I suppose ID mics would kinda work (to .001”) if you made some sleeves for the troughs.

    As an aside, (may have been stated here before) it...

    I think the OP was happy with the setup clamps he was linked to. Anyway I looked at the shop for my dog-bone clamps & found one of the small ones. The longer ones are maybe 10” OAL & this one 7 & ˝”....

    Not all tool flex, it goes through the whole machine structure to some extent. A #60 taper likely would break that endmill but will still show a little flexing in the machine tool. A 2"...
