    Here you go good buddy. Measured with a cheapo low ohm meter and verified against a semi-okay multimeter/oscilloscope.

    Standard Modern 11" (Manual Lathe)
    0.66 - 1.31 ohms from chuck to ways

    Hardinge VMC600ii (CNC 3 axis mill)
    Strange readings, assuming it's due to lubrication floating the spindle when it's turned
    Let it settle for a minute: 0.97 ohms
    Spin it slowly and let it settle over a few seconds 80 ohms
    Moving slowly by hand >1k

    Chiron FZ 08 KS Magnum (CNC 5/7 axis VMC)
    Spindle on XYZB head: OPEN (meter goes >1M, tried lots of things, couldn't get any reading)
    Lathe spindle 10k to over 300k. It looks like this is actually open, but there's some capacitance coupling the spindle to ground which changes as the spindle rotates.

    Craftex CX600 (Small Manual Mill)
    0.09 - 1.2 ohms from spindle to table

    Shark HD520 (CNC Router Table)
    Spindle is OPEN to table
    Spindle is 29 - 77 ohms to Z axis rails
