For testing drill press runout you can, with the power cord
unplugged, use a coat hanger chucked in the drill press such that it
lightly touches the drill press table top. When it is even all the
way around, the spindle is perpendicular to the table top. No
special tools needed!

??? I've never seen a precision-enough coat hanger that any part of
it would be straight/level enough in reference to any other that it
would be of any use as a measuring tool...

How does this work, exactly, again?????

It's the same procedure as leveling the table on an RAS to the blade. You
can use a coat hanger, a dowel, anything that gives you a reference
height.

He's assuming you have a radial drill press or a table that moves
laterally
and in and out I think.



No, he's not. Bend the wire like a Z. Put one end in the chuck. Bring the
table up (or the quill down) until the free end of the wire comes close to
touching the table and turn the spindle by hand. Keep creeping down until
the end of the wire touches the table all the way around as you turn the
spindle. The further the end of the wire is from the spindle centerline, the
more accurate it will be.
