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?

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. Terry Farrell man/listinfo/pianotech
