I cheated, I have a boring bar qc holder that I pass a threaded bar thru with a jacobs chuck on it. I use it for both drilling and rigid tapping. Biggest problem is when the drill is dull, the qc toolpost slips, rotating on the center hold down bolt so I lose the alignment. Keep the OLD drill doctor handy to keep the drills tuned up and its not a problem. One of those necessity being the mother of invention things. ;-) Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
