I sometimes get tool chatter with my cheap chinese lathe. I have found that wobbling the spindle speed up and down can kill the resonance. In fact this is so effective that I have considered adding a function generator comp to the spindle speed and a check-box that would automatically dither the spindle speed up and down by 10%.
You could try the same thing, see if it is a resonance that you can kill. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Mobile security can be enabling, not merely restricting.
