    Just use one normal dial indicator. If you mount it on an arm, which can just be a bent piece of steel bar, you can take measurements at 4 points (i.e. 12:00, 3:00, 6:00 and 9:00 on the clock) and compare them to find how far out the spindle is in each axis. That tool is just a gimmick to make it slightly faster.

    Thanks Johnathon. If you could post a pic for ref, it would help me. I am new to all this, so still a learning curve. Where do I get a dial indicator and which one ?.

    Here:

    For the indicator you don't need anything special, just get a cheap one:

    If you get one on a stand you'll find it useful for other things, like checking backlash and spindle runout.
