- Oct 31 6:10 PMRickDo 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.Walter----- Original Message -----From: Rick SparberSent: Thursday, October 31, 2013 4:03 PMSubject: RE: [mill_drill] RE: new article available: Avoiding Mill Head Repositioning
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.
