Overview

Ground with a U-shaped cross-section, a gouge cuts a concave channel rather than a flat plane. It is how you hollow a drapery fold, undercut a lip, or follow the inside of a curve without breaking the surface with a flat chisel. Sweep number controls how tight that curve is.

Using it

  • Match the sweep to the radius you are cutting. A mismatched gouge fights the form.
  • Cut downhill along the curve where the grain allows, so the edge exits the surface rather than diving.
  • Rotate the gouge slightly as you drive it to keep the cut continuous.
  • Use a shallow sweep for blending and a deep one for establishing hollows.
Safety notes
  • A gouge under a heavy blow can skate sideways out of the cut. Keep your holding hand behind the cutting edge, never in front.
  • Eye protection — a skipping gouge throws chips unpredictably.
  • Do not use a mallet so heavy that you cannot control the sweep.
