RE: Micrometer types - Mayhem - 12-20-2012 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. RE: Micrometer types - sasquatch - 12-20-2012 Thanks for the pic, i have never seen one.

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. "Billy G" RE: Micrometer types - TomG - 12-20-2012 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. Tom RE: Micrometer types - sasquatch - 12-20-2012 Bill, what is the manufacturer's name on that mic? I'd like to look that up if i could.

Don't worry sas, I'd wager a good percentage of users have "never seen one". RE: Micrometer types - DaveH - 01-15-2013 Here are a couple of my micrometers [attachment=4257] 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 DaveH RE: Micrometer types - PixMan - 01-15-2013 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. RE: Micrometer types - DaveH - 01-16-2013 M&W was basically UK and anywhere they played cricket. So if you didn't play cricket you didn't get them DaveH |
