  • Dial Indicator help

    I was given a Hamilton Watch Co. DI, Model 414-002.
    Can't remember AGI #'s, but the face is about 3 & 1/2".
    Graduated by .00002", .002 range either side of "0"

    There are no obvious mounts, no lugs. A knurled screw at about the 2 o'clock position that has a quarter turn, maybe a damper.

    The stem is 3/8" but the bezel is so close, both by length and clearance, none of my other indicator mounts will fit.

    Anyone know anything?

    Picture?

    probably supposed to have a lug back, or a rack adjusting back... Machinerey's handbook has the AGD info....

    Keep eye on ball.

      Sorry, no picture. Luddite.com here.
      The back appears original.
      I found one 'net reference (PDF) but the file won't load.
      Given the resolution, removed from some sort of inspection device?

        Is it possibly this one?

        With that fine of a resolution coupled with the minimal movement it is a very specialized gauge.

          You say, "The stem is 3/8" but the bezel is so close, both by length and clearance, none of my other indicator mounts will fit."

          I am not sure what you are saying here. Most DI stems have some length: at least one half inch or so. Can't you make a clamp with a 3/8" hole and a screw to tighten it? Even if you only have 1/4" of available length on that stem, you should be able to grab it. A #4 or #6 screw would fit in a 1/4" wide clamp.

          And what about the other end? Most DIs have a second stem on the opposite end which covers the moving rack where it exits the circular body there. Can you devise a clamp that fits on that end?

          A photo would really help. It is not that difficult to do. Read the sticky at the top of the General Page.

          Another thought: are there any screws that are holding the back in place. If so, perhaps you could use some longer ones to add a mounting plate there. I have seen some DIs mounted that way.

          Make it fit.
          You can't win and there IS a penalty for trying!

            This one? See post 28 in this thread: http://www.practicalmachinist.com/vb...58/index2.html

            The one in the image would seem to be mounted by a clamp on the stem.

              Mr.Hannum, looks like a winner, has the same Model # but not the brand. However that one has a longer plunger. Thank You!

              Mr. Alciatore, making some sort of mount isn't a problem; from the above I'm concluding it wasn't intended for the standard mounts, and didn't want to damage a sensitive instrument thoughtlessly. There is +/- quarter inch of stem past the bezel, with perhaps .020 between bezel and stem.

              Thanks for the help!

                Didn't notice your post earlier.
                Yes, that's it. Seems a good endorsement.
