An abrasive sanding tool which utilizes a sanding loop stretched over a tensioning body which has a narrow lateral reaction bar at one end of the loop and a cylindrical retainer at the other end of the loop. A handle screws onto the retainer and moves a shaft on the body within the hands to shift the lateral reaction bar into a position to tension the sanding loop.

An endless belt sander comprising a drive pulley and an idle pulley to control an endless sanding or polishing belt having a length substantially longer than that required for surrounding the pulleys. The belt of any desired but applicable width and predetermined length is wrapped around a workpiece of limited accessibility, regardless of the diameter of such workpiece. The belt is kept from slipping on the drive pulley by use of a pressure pulley which forceably acts upon that portion of the be...
