I made a base for a digital indicator and turned it into a very useful digital depth gauge. The collet that holds the indicator is available from McMaster Carr, MCS, and Starrett. By using different indicator tips, it can be used on very small diameter holes. The base is tool steel that has been ground flat, but not hardened.
