drill press assembly

OK clue me in on this.  Not being part of the tool police force, how is
runout controlled.  I thought it had to do more with play in the spindle
rather than lack of trueness of the chuck itself.  I've got a Delta
17-965 and it seems like it has the slightest bit of wobble in it.
Though I don't notice any inconsistency in pin block drilling, I'm about
to start drilling bridges on the press and wonder about that.  How much
runout is acceptable and how do you measure it and fix it.  What would
you look for in a non-after-market chuck or an after-market chuck?

Thanks

Check your runout on that chuck. Most chucks on new drill presses cost
about
$3. If you are not completely happy with the stability (runout) of your
new
drill, spend about $100 and get a nice after-market chuck that drills
properly. That's what I did on my Crapsman drill press and realized a
1,000%n (my estimate) increase in drilling accuracy.
