ABSTRACT:
A method of making a composite support structure and sander includes the steps of providing a rigid plate adjacent a mold such that a polyfoam layer can be formed to a front surface thereof which includes a wall defining a contained surface, the plate having a back surface for connection to a handle and introducing into the mold fluid components which react to form a polyfoam which is reaction bonded to the front surface of the rigid plate such that a back surface of the polyfoam layer forms within the contained surface and about the wall in a complementary manner thereto and a front surface of the polyfoam layer extends outward from the front surface of the rigid plate and is formed to have a relatively planar surface thereby rendering the composite support structure for removably connecting sandpaper to the relatively planar surface of the polyfoam layer.
