Micrometer types

[Bill Gruby]

Here are two more. The top one has a ball anvil and spindle. The other is the only NSK I have. It's a 2 inch. I will look tomorrow, I have some real oddballe in storage. I collect.

You should at least try to make it look good by taking the 1-2" Mitutoyo micrometer out of the plastic bag.

Nice stuff.

Ken,

Yup, I haven't used that one yet. I sure do like Mitutoyo stuff.

A few years ago i was offerd a mike that read 36 inches
I could hardly lift it ether i took it or it went to the scrap man
I cut the thimble off with a angle grinder and made a lathe stop with it
Strange how the same spindle is used no matter how big the mike

Wow! A 36" mike. I didn't know they made them that large.

You can get bigger than that
Just think about a ship engine crank shaft
They all use the last inch
The one i cut up had a webbed frame it must have cost a fortune

I would never cut up a big micrometer like that. They're worth so much money to a shop that makes big stuff!

On some other forum, years ago, there was a guy who posted pictures of his shop and the walls of his office area were decorated with mics even bogger than that one you posted in the link John.

Ken and I saw some real large ones when we toured the L.S. Starrett plant in Athol, MA last year. I cannot recall the largest but it was big.

. This is a P&W 1 inch. Take a good look. It has a wratchet but it is not the small knurled area, it is the large knurled area. Also the lock is larger than most.

Billy,

Do you know when that micrometer was made? Very nice!

That is basically a Lufkin micrometer. Pratt & Whitney bought out the precision measurement division of Lufkin in November, 1966, pretty much just changed the name on the tools and continued to sell them. Here is a shot out of the Lufkin #9 catalog showing that mic with the Lufkin name. I don't have any Pratt & Whitney mics, but I do have a few 6" rules, which are very nice.
