Micrometer types

That is a very interesting mic Bill. I've heard you speak of them before but I can't recall seeing a photo of one.

How the person uses it is quite simple. The +/- limits are set with that threaded rod at the bottom. This is done by the boss. The minus limit is read with the Braille marks to the left. Plus is read with the Braille marks to the right. If the user does not hit either of the stops the part is OK.

Interesting mic Bill, but I can't get around the thought of a blind machinist by the name of Stubs using the braille method in a machine shop.

Don't worry sas, I'd wager a good percentage of users have "never seen one".

Here are a couple of my micrometers

   

The top one is 0 -1" Moore & Wright still with it's original 'spectacle' case. Sort of a cheap M&W given to me as an apprentice 1965, no carbide ends and a plastic 'slip clutch' arrangement instead of the normal thimble.

The bottom one (0-25mm) is a CCC (cheap, cheerful and Chinese) must have cost all of $10, 16 years ago. Used nearly everyday for about 12 years - still going strong. I don't think I have ever dropped it, undone a few tight nuts with it
I'm kidding about the nuts

We don't see a lot of Moore & Wright tools here in the states, or at least in my area we don't. This area is still home to L.S. Starrett Co, the remnants of Brown & Sharpe (now part of Hexagon Metrology), Fred W. Fowler Co., and the US base for Mahr Federal Gage.

M&W was basically UK and anywhere they played cricket. So if you didn't play cricket you didn't get them
