Digital Height Gage (almost finished)

[TomG]

Chuck,

Rather than use a round scribe, you should consider making it out of flat stock. It can then be shaped so the scribe point is flush with its lower surface, enabling the height gauge to be calibrated by running the scribe down to the surface it is resting on. The scribe can be made into an L shape to help it reach and/or the base can be slotted for clearance.
