  • Dial test indicator operator headspace

    CAUTION - incredible stupidity involved and possibly contagious

    I solved my earlier posted problem with an Interapid dti reading 0.012" on a 0.010" movement.

    I feel so ashamed to admit this but the indicator is actually 0.008" full scale. As I turned my lathe compound and watched its micrometer dial, I did not look up until the dti was reading 0.002" past zero (0-4-0 dial).

    For some reason, I had assumed it was 0.010" per revolution and expected it to stop on zero. The dti was reading perfectly

    Now I will go and hang my head in shame for a month.
