0-1 Micrometers

I don't very often use a micrometer these days, preferring the digital six inch rule otherwise known as a digital caliper but I was doing a job that required that little bit more accuracy and so went in one of my measuring instrument drawers for a 0 to 1 mic.

I realised that I have 4 very different ones to choose from and wondered if others might be interested.

The picture shows, at the top, my first mic, a normal sized but elderly Brown & Sharpe.

Below that is my first mic, another Brown & Sharpe but much bigger and heavier.

Next is a quite modern TESA which is the one I normally use and finally, a GKN Shardlow digital but it's a mechanical digital and not an electronic one.

If I could choose, it would be the Tesa.

I have around 4 or 5 if I include the 0 to .5 Just bought a new 0 to 1 because the older ones, some I have had for 55 + years are getting harder to read. Until I got the new one my go to was a Mitutoyo I bought around 1970. Maybe when they where first imported ? All the old hands told me I was wasting money because it would not last.

We were left an 0-1" Mitutoyo mic in a legacy, it is one of their early ones, in a tiny box with a picture of their Tokyo factory inside. The early ones have slotted screws for the lock and ratchet.

Any one that reads zero when closed and is accurate when checked with a test piece at the 1” size?

Lucky you, to have the choice of some decent examples.

I would more than likely choose the 0-25mm one, but all to their preferred system. I’m not even sure if I have an analogue metric micrometer of that range, so it might be the really too-precise mitutoyo digi, that tends to eat the cell if it is left in.

... which would fail your first test

Nice selection. I used to have a GKN Shardlow like the bottom one. I was gutted when it disappeared from my bench one day at work. Was always nice to use and accurate.
