    I measured the diameter of one of my arm hairs with my newfangled digital calipers. It's .00034" in diameter. These calipers only cost me $30. I forgot how much my old school micrometer cost, but it was a lot more than $30. Some things are better nowadays.

    So quit yer whining about the good old days

    In general, machine shop stuff gives me the happies. I guess that's cuz I spent a lot of time in the garage with my dad, who designed helicopters for Hiller.

    Not to take away your fun , but I do not want to help encourage cheap / low quality tools , we are already short of people that are able to use them to make & repair .
    Dang , I probably did ;(
    Started metal working in 8th grade machining , welding etc. --- that does not happen anymore ;(
    I had a fire a couple yrs. ago & lost about $250,000 in tools & equipment .
    Went buy a replacement digital calipers , couldn't afford the $150 - $200 ones , so bought the $30 ones .
    If you get a chance / know someone that has a good pair , work-em side by side - a huge difference .
    You may get the same / correct readings , but the cheap ones are soo ruff , you could not do a lot of measurements as quickly , or as easily .
    It takes more finesse to make a poor tool work well , as compared to a quality tool .

    Yeah, you do still get what you pay for. The difference is that nowadays the economy options are pretty decent and the average guy can afford them. Same for radios, scopes, spectrum analyzers, etc.

    The high end equipment is still there and if one really needs it professionally it may still make sense to buy it. At work I used scopes and other equipment that each cost as much as a house and were well worth it. Now for my hobby use I have a $350 Rigol scope. I also have an HF micrometer :).

    I've never seen calipers that measured down to 1/100000 of an inch.

    Maybe 1 decimal place off.

    I've always used Starrett scales and instruments - but I'll tell you, some of these "disposable" Chinese digital calipers are not all that bad. :eek:
