    Actually we didn't wonder.
    "We"? Reminds me of Queen Victoria's famous remark "We are not amused".
    Royalty never refer to themselves as "I".

    In the States, some Insize products are carried by Wholesale Tools:

I will increase that to 10mm and try again.

    In the meantime, I have found out about an Austrian brand that carries a lot of stuff that I have been searching for. The company is Insize. Headquarters are Austria, but it seems manufacturing is done in China. Bought a 50-75mm OD micrometer for $40. At home, I checked it with my 50mm Mitutoyo reference rod and it yielded exactly 50.00mm. Not as cheap as the ones that a Chinese farmer hammered out of soup cans, and not as expensive as a Mitutoyo. They even have the telescoping gauges! Would love to hear other people's experiences with this brand...
    I know the company INSIZE and the products are made by a Chinese company that isn't exactly popular with other Chinese manufacturers. I think the dislike had more to do with their sales methods than having an inferior product.
    I doubt if they still have but their agent in Austria was in fact English and before moving (?) to INSIZE had worked for Moore & Wright in England.
    I last spoke to them at an exhibition in Germany. The Chinese at the stand were definately NOT working for the agent. Vice versa.
    They don't seem keen on writing who owns the company or where HQ is based.

    With that remark I can't resist this 'un

    I hear the US is moving towards metric - inch by inch.

    Of course it's "safe" but I don't know as how I'd want to buy if you sell what you make

    Though I stll want to point out that nobody (else) suggested using (just) calipers, it was the OP who used them. While they are not accurate to the 0.01 mm in their readings, they can be used to transfer the dimension so it is easy to measure with a micrometer. Been there, done that hundreds of times, got the T-shirt

    Again, I do apologize for my bastard behavior and welcome you!
    Jaakko, no apology necessary. Even on a good day I can be a PITA It's below zero here too.

    I've been in Finland twice and loved both the country and the people

    Back to the title of the original post in this thread which is:

    ID micrometer, is it worth buying one?
    And from the texr of the post:

    Originally posted by taydin View Post
    I am currently making seats for 8 bearings, like the ones below. Made the first one, but really struggled with measuring using my caliper. I needed to spend several minutes seating the caliper properly, getting the right feeling about the caliper position and reading the dimension. This first one ended up being a nice tight fit.

    So my question is, will buying an ID micrometer make things easier? Based on how those look, it seems I will still need to spend several minutes positioning the mic to the hole, getting that right feeling and making the measurement.

    For others: is it worthwhile for the OP to buy an inside micrometer - or not?

    For the OP:
    the decision is yours alone.

    Thanks for the welcome folks

    As I live in Denmark (originally from Scotland) I didn't take the "warm" welcome too seriously although as he is from Finland it did surprise me They had to be neutral for decades so I guess he was just letting of some steam

    On the subject of caliper accuracy (and it happens to be another of my specialties) then this might interest some. To change from mm to inches divide by 25.4. Don't use any other method
