A motor-driven wheel for sanding irregular surfaces including a plurality of flexible support members projecting generally radially outwardly from a hub assembly and a plurality of separate nonconnected lengths of flexible abrasive-coated material projecting along the support members from within the hub assembly. Each of the lengths of abrasive-coated material is releasably secured in the hub assembly by separate members positioned adjacent the periphery of the hub assembly which permit, when released, individual movement of the individual lengths into or out of the hub assembly.

Sanding wheel

A tool including a wheel of a firm material adapted to be rotated by a drive assembly, and a support strip of elastic resilient cellular material permanently adhered around a cylindrical peripheral surface of the wheel with its leading end in a slot in the wheel. A predetermined length of pressure sensitive adhesive coated finishing material may be removably adhered around the outer surface of the support strip with its terminal end in a deeper portion of the slot which is disposed to press the end of the length of finishing material into firm engagement with the leading end of the support strip.
