ABSTRACT:
A work-polishing tool including a rigid annular core having at spaced intervals around its periphery strips of readily-deformable material such as sheet rubber. These strips extend radially outwardly from the core and each has leaves of abrasive fabric secured to its extending end. The inner ends of the leaves are spaced an appreciable distance, for example, one fourth inch, from the outer periphery of the core. The core may be formed of an annulus of thin spacers in which the strips of readily-deformable material are interspersed at spaced intervals and which is rigidified or solidified by injecting adhesive, for example, an epoxy resin and a hardener, between the spacers and between the spacers and the adjacent strips and permitting the adhesive to solidify. The strips may be folded over so that they are of U-longitudinal section and the leaves secured to the arms of the U. A loop is then formed into which a block of cardboard or the like is inserted. The loops with the blocks and spacers are then locked together on a metal ring into a rigid annulus. Separate pluralities of leaves may also be connected to each folded-over strip of U-section. The strips are then strung onto a metal ring and an anchor pin is interposed between the head of each strip and the ring. The strips and anchor pins are then locked into a rigid annulus.
