Default How do you measure runout on drill press?

I have a quill play in my Frox Shop 17" drill press.
When rotating with no load the runout is just 0.002" but if you move
chuck with your hands back and forth test indicator shows 0.030 runout.
Woodstock Int. (manufacturer of all Fox Shop tools) warranty guy is
saying that I am not suppose to try to move chuck while measuring
runout. "The right way" to measure runout is to do it while drill runs
on lowest speed with no load.


They are correct. You aren't returning the machine because of runout, you are
returning the machine for excessive slop in the quill. Get your money back, and
next time read http://www.tinyisland.com/htbdrillp.txt before buying one, and
don't buy an import DP without inspecting it in person.
