Securely attaches a dial indicator to a Mark Smith aftermarket Z Plate designed for the MillRight CNC Mega V machine, but you could use this bracket to mount a dial indicator anywhere with M5 holes with centers spaced at .75" (19.05mm). I used two M5x20mm socket head cap screws to mount the bracket to the spindle clamp, then a ¼-20 x ¾" machine screw and nut to secure the dial indicator to the bracket.
