I'm having some issues with my PSI collet chuck. I turn the blank round, down to 5/8, and when it comes time to put it in the chuck for drilling I have one helluva time getting it to stay straight when tightening, or even getting it straight in the first place. It keeps ending up with me tapping it repeatedly while the lathe spins at 250 RPM until the hole from the dead/live center is the least "blurry" I can make it.
I figured the tolerances for a collet chuck were so tight it would pretty much be "slip in blank, tighten, drill". What am I screwing up?
