Hello everyone -- long time lurker here, finally found a good reason to post as I've had some trouble drilling holes for my segmented blanks that remain centered throughout. I've recently transitioned to using my lathe for drilling and I've been using a Nova G3 chuck with Pin Jaws in the headstock and PSI 1/2" drill chuck in the tailstock. I invested in some fantastic flute bits as well, which do much of the work themselves of clearing dust as I move the bit forward (I go pretty slow and typically only have to back out a few times to clear).
As you'll see in the photos attached, I don't have any problems starting on-center.. the issue is getting out the other end centered, and I'm not sure why I'm getting so much drift. I have noticed a fair amount of wobble on the drill chuck as I move forward, but I wasn't sure if this could be causing the problem. I should add that my lathe is a Delta 46-460, and I typically drill at 1350 rpm.
Any thoughts?
