  • Hieght gauge

    This is probably old hat to most of you guys but, it's new
    to me as I've never had one or even had my hands on one.

    This one I made in my shop using a cheap digital 6" caliper.

    I made it because I was having an awful tough time trying to
    get a reading of the height of a part while hand holding a
    dial caliper and just could not get consistant readings.

    Once all the parts were assembled, I locked the caliper
    and "lapped" the base unit and the extended jaw as
    a unit using progressively finer grits of wet dry paper
    on my surface plate.

    The digtal caliper reads 4 places to the right of the decimal,
    although the last character either reads blank or "5" for
    a half a thou. and nothing in between.

    The gauge seems to allow a much more controlable reading.

      Anyone recognize the red thing just to the left of
      the newly made height gauge?

      It was given to me a couple years ago and tucked away for
      a while as I did'nt really know what it was, and it was stiff
      as a board and did'nt seem to rotate.

      Well, during a recent rearranging, I found the red thing
      and decided to disassemble it, clean off all the old dried
      up grease/oil that was acting like glue preventing it from
      rotating, and re-oiled and assembled it.

      It has a collet that I had'nt seen until now.
      The collet looks like it's made more of "air" than metal.

      Looking up on google images I found out that it
      is a collet for the work head of a valve grinding
      machine, which is what the "red thing" actually is.

      Google can be a great help huh?

      Can you tell what I'm up to with the work head
      and the spindex?

        My plan is to convert the work head into a tailstock
        to use in combination with the spindex on the
        mill table.

        The height gage allowed a good reading to determine
        the amount the work head needs to be raised to
        bring it up to the same center height of the spindex.
