    Default What "advanced" metrology gear do you have?

    I see folks in various threads suggesting the use of sine tables or bars or gauge pins and blocks for various task solutions. So I'm curious as to what folks have managed to buy or make along the way for measurement and test instruments. Let's start with the basics and work up from there.....

    To make it easier to read and tabulate at a glance please cut and paste the block of options below and modify my own "yes" and "no" to suit your own collection. And then add any comments after that please.

    Sliding calipers (vernier, dial, digital)- yes
    Micrometers- yes
    Dial gauges- yes
    Test indicator- yes
    Sensitive (.0001"/.001mm) test indicator- no
    Telescoping gauges- yes
    Small hole gauges- yes
    Bore micrometer- no
    Granite or iron surface plate/table - yes 12x18 in
    Sliding height gauge- no
    Height tester - yes (shop made)
    Precision test centers - yes (shopmade)
    Reference square - yes (shop made)
    Gauge block set - no
    Gauge pin set- no
    Sine table or bar- no
    List any other advanced measurement gear you have which isn't covered.

    Other items in no particular order-
    Various sensitive or heavy item scales-6
    laser temp sensor-3
    fancy shmancy stabilized laser and nothing else
    Good Depth gauges - HOW DID I FORGET ABOUT THOSE ! ? -2
    Thread wire sets (another faux pas on my part) - 4
    And the coupe de grace.... a tool room microscope...... <drool>-5
    USB or older optical microscopes. This sort of fits in with the tool room microscope but perhaps not quite on the same level.-3
    Machinist's levels. Another DOH! moment for me. So far - 9
    Depth micrometers- 7
    Optical comparators - 3
    Radius gauges-6
    Balancing stand
    Surface finish comparator or comparison set- 3

    A couple of you are confused by my height tester. I may have the wrong name but it's a base with a column that you can attach a DTI onto and test the height of items. Some might just use a magnetic base or others may be using a sliding height gauge with a mount for their DTI. The really nice ones can also angle the finger for the DTI down or up to nearly vertical and with the bumper on the base use them as squareness comparators. I hope that clears up THAT entry.

    The fancy stuff lower on the list seems to be rising up in the percentages. Over half of the present list of responders have gauge block sets. And just under half have sine tables or bars.

    My list of metrology items is severely lacking. I started to acquire Mitutoyo outside mic's, and buy as I need something. No sine bars, no gauge blocks or pins. Do have a surface plate and height gauge. A couple of crappy HF calipers, and a set of tiny telescoping gauges that I suspect are fake Mitutoyo from Amazon as they feel Chinese with a Chinese or Indian finish.

    Gear tooth vernier callipers, imperial and metric.
    Not used often, but useful when they are needed.

    Thanks, that's a great start. I'll give it a couple of more hours then do the first tabulation update.
