Belt sanding apparatus including a frame having parallel, spaced horizontal tubular elements, mounting head elements which are slideably positioned on the horizontal tubular elements, table members pivotally attached to vertical tubular elements adjustably mounted in the mounting head elements, the table members being adjustable as to fixed positions relative to horizontal about an axis perpendicular to the horizontal tubular elements of the frame, and a sanding mechanism, mounted upon an arbor element which is pivotally attached also to vertical tubular elements adjustably mounted in another mounting head element, the arbor element being adjustable as to fixed positions relative to horizontal, with the sanding mechanism including a rotatable sanding belt, a guide for the sanding belt adapting the belt to travel an extended path transversely of the horizontal tubular elements of the frame, and further including the motor drive for the sanding belt, whereby the apparatus is adapted to expose the edge of a work-piece, e.g., a flat wooden board, placed upon one of the table members to varying vertical angles of contact, i.e., from zero to 90 degrees, with the rotating sanding belt to sand the work-piece in a direction transversely of the horizontal tubular elements of the frame.
