Reading a 1/10000th micrometer

This has to be one of the strangest thread starters I've seen here. Why would admin. delete your message but keep the thread place open to be read? I'm sure that there's a reason you started to ask about making some kind of measurement at the 100 femtometer level but for now you've just baffled me.

did admin do it or I'm thinking ronseto did it.

No! I deleted it. I realized after writing it, it was a dumb question, but couldn't delete all, only the actual text.

great, now look what you did, you started something, but we don't no what it is yet......do I post this off-topic?

I have to believe that you know how to read these things.

I'll bet you can't anymore, if your eyes are as bad as mine. Calipers are worse than micrometers for me.

Thank modern technology for digital.

veneer caliber suck, dial calibers are still ok. digital are king. Have someone else do it for you is brillant.

I favor vernier reading tools over dial or digital, although I have all types in my arsenal of measuring tools. The fact that I have to zero in my digital caliper each time I take a reading, leads me to think the tool is not perfectly precise. To me, those little lines on a vernier do not lie.

I get the most consistant results with my vaneer......but reading metric those lines are too dam close..

I still won't switch to metric. I'm happy with my feet and inches, so no need to change.

I back you on the vernier approach - call me a Luddite but I don't trust those digital things. Then there's the duff battery problems, and neither digital nor dial jobs work very well after using them in situations where the only applicable tool is a very small hammer .

Pussnally I have no problems with metric ones - given a decent pair of specs .

I grew up with slide rules, which may to some extent explain my preference.

Huh? What was that...

I couldn't hear ya.

That too.

Figure 4-8. Micrometer Barrel

It's the thimble graduations.

OK my OT was: Is it possible to extend the range of a ten thous mike by estimating the space between lines on the barrel? For example, can you read .43745 on a ten thous mike? Is the resolution limited to the readings on the tool? I deleted it because I realized the space between lines on the barrel were too close to further subdivide.

thanks for clarifying ron.... it works for me Ray

You can subdivide the .001 graduations on the thimble, but not those on the barrel.

Like I said, if you can see them.
