Working With Warped Wood

Working with thin wood may present a unique set of challenges. The process of resawing lumber yields beautiful results however you do run the risk of inducing a small warp. With the right techniques and tools, you can tackle any issue that may arise.

Understanding why wood warps

Warping occurs when wood dries unevenly or reacts to changes in moisture and temperature. When resawing, the process releases tensions in the board and may also induce warping. Thin wood is particularly susceptible due to its lack of rigidity and high surface area relative to its thickness.

Common types of warp include:

  • Cupping: When the edges of the board rise
  • Twisting: When the corners twist in different directions
  • Bowing: When the board curves along its length

What do I do if my wood arrives "warped"?

Firstly, this is in the realm of normal and is not considered a defect so refunds are not applicable.

Simply use clamps and/or heat to bring your piece back to normal! Here are our two favourite methods:

Moisten & Clamp
Lightly moisten the warped area, then use clamps to press it flat. Allow the wood to dry in the clamped position.

Heat Treatment
Applying heat can also help reshape warped wood. Use a heat gun carefully to warm the wood, then clamp it flat and let it cool.

Final Tips While Working with Warped Wood

  • Be sure to store your wood in an environment that has consistent temperature and humidity
  • After your project is complete, apply a finish on all sides
  • Be patient while removing the warp and feel free to reach out for advice during the process
