An apparatus and method for forming a valve seat while the valve body is positioned in-line are disclosed. The valve reseater apparatus (25) includes stabilizers (27) for positioning the valve reseater (25) near the valve seat (21) to be repaired, as well as a cutting tool (42) mounted on a tool head (41) which is rotated by means of a revolution shaft (44) interconnected with a motor (34). The cutting tool (42) is simultaneously translated by means of translation screws (66, 67) which are controlled by means of a rotatable hand knob (56). The circumference of rotation is automatically controlled by means of a star wheel arrangement.
