ABSTRACT:
A hand-held centerless grinding apparatus for grinding and refinishing convex, concave and flat surfaces. When a surface has been grooved or otherwise indented, the damaged surface can be built up, then must be ground back to the original configuration. A box-like body structure having and open side has inwardly extending V-shaped openings in opposite end walls. A grinder having a drive motor and grinding wheel is mounted on a bracket for grinding wheel movement along a line bisecting the V-shaped opening. The box structure is arranged with the open side against the surface to be repaired. In the case of a shaft, the sides of the V-shaped opening engage the shaft. The bracket is adjusted to bring the grinding wheel to a position conforming to the intended surface configuration. The motor is turned on and the body is manually moved along the surface so that the grinding wheel grinds away any repair material extending above the desired surface. In another embodiment, the body is formed from a solid block of material by machining, casting, etc.
