Default How do you measure runout on drill press?

Grant,

you wrote an excellent article.
As for import DP it looks to me that you won't get anything with 0.001 runout for less
than $400-500 and even that number is very optimistic.

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.
