Dial Indicator Rod Extensions

I make my own dial indicator rod extensions from 3/16 diameter O-1 drill rod. These can vary in length from 1” to 6” depending on the application. I hold a 4-48 die in the lathe tailstock die holder to cut the male end and cut 0.050” thread relief at the shoulder to provide a tight fit into the dial indicator. The female end thread is 4-48, threaded approximately 0.030” deep, and the first two threads are drilled out for a tight fit. Some examples of the various uses for the extensions include digital depth indicator extension on a small milling machine, hard to reach measurements with the dial indicator, and adding more travel length to a lathe carriage measurement where each extension is exactly 1” long. Thanks for looking.

Thanks Paul! I've added your Dial Indicator Rod Extensions to our Measuring and Marking and Metalworking categories, as well as to your builder page: Paul Jones' Homemade Tools. Your receipt:
