    I am a tool hound. I love weird tools.

    This one was weird to me. Its almost like a joke piece. No way this thing could hold any dimension.

    Three foot tall Starrett square.

    Yes. love you guys are tool folks. JR

    Old Interferometer, it will measure distance down to a millionth without any issue. Other attachments can measure angular deflection, flatness, etc. I was able to measure the backlash in a starrett micrometer head in the lower pic. I have a newer one that should be able to do down to .3nm. These are often used to map ball screws on cnc machines, also they are used for positional feedback instead of encoders on machines that work with ICs on semiconductor wafers.

    as generations of brilliant and skilled model engineers have shown, you don't need a ton of fancy expensive equipment to turn out incredible work. But it is a heck of a lot fun and makes it easier/faster. i think I have everything mentioned in this thread plus tons more, I think I've 22 boxes at the moment plus lots on shelves. Well, I don't have an interfermoeter, it was no brainer macona would win measuring measuring contest. I did get to use one very neat. One practical use is a cheat for a carnival weight guesser - you can get within a few pounds by measuring concrete slab deflection when someone stands on the spot. The owner of it is a nut job so so don't play with it anymore....other the cool factor, not sure when I'd do with it. They're not hard to use but irrc, you do have to worry about/compensate for air density, and of course when you measuring millions temp matters. I've 1/100,000" mechanical comparator as well as a federal 1/100,000" indicator but passed on the 1/1,000,000 comparator (was in Spar, used to sort balls for the bearings for the Canada arm). Other than curiosity/pride of ownership I just couldn't conjure a use for it

    I was looking through the thread thinking I bet no one has a 36" square.....and then JR posts a pic! too funny, couple toolaholoics to have crap like that kicking around.

    Of course 99% of time its all covered off with a couple of mics, digital caliper, dti, telescoping gauges, depth mic, square and maybe small hole gauges....but its been fun wheeling and dealing and collecting the tools. Its only hoarding if you don't use them

    LOL, I do have some shiny toys. The cards for the other interferometers are VME so I have to figure out how I am going to talk to those. Fun.

    I didn't see these I believe so I will list some additionals I have

    Precision Square (Starrett)
    Precision Level (Starrett)
    Cylindrical Square
    Gear Measuring Pins ( Van Keuren)
    Gauss Meter (Magnetic measurement)
    Surface Finish comparator

    Rich
    So you have at least one of all the other things on the main list? I was looking at the initial list as being items to tabulate for the results in my first post. I'll leave out your entry until this is confirmed.

    The lower list in the first post is tabulated up to this point.

    BC, when you listed height tester I gather you meant what I know as a surface gauge. Sure, I've got one of those.

    One other thing I remembered - ten or twelve years ago a friend gave me a box of tools that had belonged to his grandfather. One nice item was a mechanical tachometer (Starrett). It has various size contact wheels that you touch to your rotating work or tool.

    Works fine, but I don't know why anyone would want one now instead of a simple electronic tach.

    There are no stupid questions. But there are lots of stupid answers. This is the internet.
