      Do not discount the lowley Coaxial indicator.
       
      Mine gets used regularly for such tasks as checking lathe tailstocks to see that they are "on centre" with the headstock spindle.
       
      I often get jobs in that require aligning to an existing hole and re-drilling, or boring out in size and it is quicker to set up the co-ax and dial it in, than it is to attempt to set up and find a reference point to set up and zero the DRO to, especialy if the hole spacing is not a known entity.

      Malcolm,

      I lost interest in the coaxial indicator when I got my DRO.

      You can make one for yourself. The mechanism is not difficult, well within the capabilities of most. You can use a DTI or as I am doing the mechanism from an old pressure gauge. You don't need accuracy, just repeatability. The design for one was in August / September MEW 2006, available if required or, alternatively, look up the patent as I did.
