Abstract
A tool for refinishing a workpiece such as a brake drum includes an arm for a user to grasp the refinishing tool during operation. A pivotal swivel member is connectable to the arm. The swivel member is formed with an asymmetrical shoulder for compressively and rigidly fixing the swivel member and arm in a fixed linear alignment coincident with a longitudinal axis through the arm and swivel member during a refinishing operation. The asymmetrical shoulder also orients the swivel member in any angular position within a continuous range between zero degrees and forty-five degrees in one direction from the fixed linear alignment. A coupler is formed in the arm and in the swivel member to removably connect the swivel member and the arm. A plurality of demountable locking devices is included for variably positioning the swivel member in relation to the arm. A cutter is detachably mountable on the swivel member, and is adapted to refinish the rotating workpiece on a lathe.
