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.

That's a beauty Marv, reaching otherwise inaccessible places answers a lot of issues in machinery repair. As micrometers increase in range, the frames deepen logically, but some repair work throws a wrench into the works only specialty items remedy.
There is another benefit; can be zeroed at any position or reading for comparative measurements against a sample or gauge. The Uni-mikes and other interchangeable anvil mikes don't have anything like it. Even a hub mike depends on a rigid frame.

very nice Marv I used to have one of these little numbers for measuring the grove widths inside of a hydraulic cylinder gland at times like you described I needed a mic to get in a tight spot this came to the rescue only had to deduct the zeroed thickness without true anvils on the undersides of the jaws body close was all I could expect but it was a lot closer than horse shoes & hand-grenades
made by that weird guy Starrett

I never got around to doing it but it would be a doodle to make an attachable cylindrical anvil for it and use it to measure wall thickness on cylindrical surfaces, e.g., tubing, pipe...

I like it.

I think we'd all be in shock knowing the full range of talent, right here within HMT.net
