This is a dial indicator mount to measure runout on a lathe equipped with a CXA tool post holder.  Features a split holder with crush-ribs to create a tool-free snug fit on the indicator. The indicator can be easily be remove and securely positioned at 0 or 180 degrees to check both axial and radial runout.  The mount was designed for the Harbor Freight PN: 63521 (https://www.harborfreight.com/1-in-travel-machinists-dial-indicator-63521.html) but may work with other brands.  This design is in imperial units and hardware sizes (sorry but it is what I had on hand).
