Adjustable micrometer

[mklotz]

I needed a micrometer that would fit into a tight area where the frames of my commercial mikes just wouldn't go.

I made a fitting to hold a 0-1" micrometer barrel. As long as I was about it I decided to make it adjustable. The sliding rod converts it into any size between 0 and 3". The extra narrow anvil gets into really tight places.

Is it as accurate as a conventional mike? Of course not but I don't build spacecraft (although I had a hand in designing a bunch of them).

Since I built this I've acquired a 0-0.5" mic that handles many of the situations this tool was built to handle. Nevertheless, it still gets used occasionally.
