If you can keep a consistent angle of pull with abrasive cord, and rotate it so that you create and follow the radius you are trying to create, then more power to you. Simpler by far is using the Foredom/Q-tip, and less invasive and uncontrolled. P In a message dated 11/27/2009 10:15:10 P.M.

I think the abrasive cord might be easier to work consistently than the file (unless you feel you need to aggresively remove some material).
