Techniques for Sanding Different Curves

Curved table legs often feature a combination of convex, concave, and intricate decorative shapes. Each type of curve requires a slightly different sanding approach to maintain the leg’s profile without flattening or distorting it.

  • Convex curves (outward bulging): Use a flexible sanding block or a foam sanding pad that contours to the surface. Sand along the grain to avoid scratches, applying even pressure.
  • Concave curves (inward curves): Wrap sandpaper around a dowel or a contour sanding tool that fits the curve’s radius. Move the tool gently in a circular or back-and-forth motion to smooth inside edges without rounding them off.
  • Intricate details and grooves: Utilize folded sandpaper or small sanding sponges to reach tight spots. For very fine details, consider using sanding sticks or even fine steel wool to avoid damaging delicate features.

Tools and Accessories to Facilitate Sanding Curved Legs

Using the right tools can significantly improve efficiency and the quality of your sanding work on curved table legs.
