Abstract
A pair of guide wheels are provided for a manually manipulated abrading device of the endless abrasive belt variety for preventing the gouging of the surface of a workpiece when a raised imperfection, such as a weld bead, is abraded by operation of the belt to lie flush with such surface. The guide wheels define an annular and radially outwardly opening groove in which a tire formed of a relatively non-deformable material is supported to undergo relative radially directed displacements incident to rolling of the tire along the surface of the workpiece. The guide wheels are adjustable to vary the width of the groove for purposes of controlling the extent of radially directed displacements of the tire, and thus the position of the belt relative to the surface of the workpiece.
