Extension handle for a Starrett solid-rod inside micrometer set

[Paul Jones]

Thank you Toolmaker51 ,

This time I took advantage of the Starrett website where ironically they published the blueprints to some of their tools and luckily for me they had the simple blueprint to the extension handle for a Starrett solid-rod inside micrometer. Starrett blueprint has the exact thread specification. However, in more cases with adding additions to Starrett tools I had to measure the thread pitches and diameters with the tried and true ways using thread gages and three-wire method of measuring threads. It is not difficult but using the blue print is so much easier.
