Abstract : A grinder for preparing circular seats behind elliptical handholes of marine boilers. An air motor, mounted within an expandable housing, drives a grinding wheel against the inside surface of the handhole. The housing is expanded to be secured in the elliptical handhole. The center of the motor orbits on a circle about the center of the housing so that a circular seat is formed about the inside edge of the elliptical handhole.
