I have the PSI dedicated chuck and a 3/4" keyless chuck. I have tried it a couple of times and continue to get run out. I'm on slowest speed on the Jet, going in 1/2" then clean, Bit is sharp, 60 degree center points are matched up perfect if tailstock spindle is locked in place. When the tailstock spindle isn't locked in place, like when 60 degree center points are not matched up and I can lift up on the tailstock 60 agree center it moves at least a 1/32". Same when the keyless chuck with a bit is in, it's perfect, but when I unlock the tailstock spindle it moves up and down 1/32". Is this what is causing the run out? You can't lock the tailstock spindle in place when drilling so, how do I stop the run out?
It seems like when I pull the bit out after going in 1/2", the bit end rubs on the end of the blank reaming it out.
