Model #11374: Our Inflatable Long Drum Sander is perfect for sanding long flat and curved sweeping surfaces. Because this sander works best with very low air pressure it will conform to the shape of your work, e.g. the base and outside of a free form or turned bowl. Manufactured from very high quality, cloth backed sandpaper, the sleeves eliminate scratches and allow you to apply the sander's total width against the work piece, or use only the edge in all kinds of complex sanding. To eliminate deep scratches or gouges, start with the coarse, heavy 80 grit working your way up to the fine 220 and extra fine 320 grit sanding sleeves for a final finish.
