    i am in the market for a micrometer set. my first one.

    do i buy the set that reads to .001" or .0001". the price difference is over $200 (canadian).

    everyone i spoke to has different opinions. some say for the home engine builder/hobbyist .001" is more than enough, especially when you can eyeball between the markings.

    but others say that even the most simple motor rebuilds should have reading capability to .0001".

    cost is an issue, but not at the sacrifice of quality. any help?

    TIA

    If cost is important, get the .001 for now, then if that doesn't work for you, sell it and save up for the .0001 /forums/images/graemlins/waytogo.gif

    Depends on what you are doing. Do you have the tools to make parts down to .0001". You need a pretty nice lathe to hold that tolerance. Not many things need to be more accurate than .001" since not many machines are accurate to that tolerance. I've been a machinist for a few years now with medical device companies and I have yet to truely need .0001" on my micrometer. However it is nice when you are checking really small cylindrical fits and such.

    I have never used a .0001 micrometer and see no use for it unless you're working on something more critical than I am.

    I agree with sickquad....you shouldn't need anything smaller than .001. Good quality micro's should have line bars on the handle to show .0001 anyway. Unless you are getting digital/forums/images/graemlins/peace.gif

    All of mine are in the .001 range.
    0 - 5" outside mics
    0 - 8" inside mics
    0 - 6" depth gage

    well i spoke to a engine builder here. i am deciding on the .ooo1".

    after the few engines i have built (really enjoyed it), i really want to get in to building higher horsepower motors. i was told that in the long run the smaller reading will come in handy.

    also, this evening, the wife has approved the additional funds. /forums/images/graemlins/whistling.gif

    thanks for the opinions.
