I think I see some of your chatter problem. You have an awful lot of holder sticking out of the spindle. I would have used a 1/2 inch set screw holder. That would have shortened your holder up by an inch or more. And that is not a Tormach spindle. Your long spindle nose could also be contributing to your problem, although that ZRN coated cutter seemed to work pretty well.
