Yes and no...
With the webcam the axis of the spindle is the pixel that doesn't move
when you wiggle the spindle back a
$200 is the import version. The good ones are *MANY* times that.
There are no specs on the import but the good ones are tenths
reading/accurate. Often w/ replaceable templates so they work as a
mini optical comparator (sort of a mini toolmakers microscope
reticle.) They were used with jig borers

Richard,
Interesting device, but...
To avoid errors, I would have thought you need to eyeball the centre dot
directly, from above, otherwise the axis of eyeball and dot is at an angle and
will only be coincident with the spindle axis at one point along that axis.
I use a "proper" centering scope
check enco i think they have them for 25 or so
