Abstract
A sanding block is disclosed having an elongate shape having a constant cross section along most of its longitudinal axis. The sanding block is formed of a flexible material and has a curved upper surface and a flat lower surface. The curved upper surface has a width less than that of the flat lower surface but has an arc length about equal to the width of the flat lower surface. The sanding block is used by securing strips of sand paper to one or both of the upper and lower surfaces. The width of the lower surface and the arc length of the upper surface are preferably chosen to be about equal to the width of the sandpaper.
Claims19
A method for sanding surfaces comprising:
- adhering a first sheet of sandpaper having a rectangular shape defined by a width to a flat lower surface of a sanding block having a curved upper surface;
- and
- adhering a second sheet of sandpaper to the curved upper surface, the second sheet having a rectangular shape having a width equal to the respective width of the first sheet, the curved upper surface of the sanding block having a first width and having a first distance across the curved upper surface, the flat lower surface of the sanding block having a second width, the first width being narrower than the second width and the first distance across the curved upper surface substantially equal to a second distance across the flat lower surface.
A sanding assembly comprising:
- a sanding block having a curved upper surface and a flat lower surface opposite the curved upper surface, the curved upper surface having a first width and having a first distance across the curved upper surface, the flat lower surface having a second width, the first width being narrower than the second width and the first distance across the curved upper surface substantially equal to a second distance across the flat lower surface;
- and
- the curved upper surface configured to receive a first sheet of sandpaper to substantially covers the curved upper surface, and the flat lower surface configured to receive a second sheet of sandpaper to substantially covers the flat lower surface, the first sheet of sandpaper and the second sheet of sandpaper having widths about equal to that of the flat lower portion.
