Why is it important to leave a thin layer of uncut material on one face in kerf bending?

What affects the bend radius in kerf bending?

How can the shape be set in kerf bending?


  • Kerf bending is a technique used to make curved structures from various materials, including wood, plywood, MDF, and vinyl.
  • The process involves removing small sections from a piece of material until it becomes flexible while still maintaining its integrity.
  • The cuts should not go all the way through the material; leaving a thin layer of uncut material on one face acts as a ligament.
  • Appropriate cut depth is important for material flexibility. Plywood is often used as a depth reference.
  • Testing on scrap materials is recommended before bending the main piece, to determine the optimal cut depth and flexibility.
  • Spacing of cuts affects the bend radius. Closer cuts result in tighter radii, while wider spacing produces shallower curves.
  • Two methods for setting the shape: 1) gluing the curves shut, 2) using another piece of material to hold the shape while bending.
  • The technique can be used to bend the material outwards as well, but requires more care and may involve saturating the material with water or steam.
  • Curve bending can be achieved with various tools, including a miter saw, radial arm saw, table saw, or circular saw.
  • Always practice safety precautions while bend bending.
