Wood Panels and Humidity

Written by Dave Markel

Coping with wood movement

All wood workers need to be aware of wood movement when building furniture projects. Failure to consider this important factor can cause wood panels to crack or split.

My high school biology teacher comparedrepparttar structure of a piece of wood with a bundle of straws. The straws representrepparttar 116261 cells and capillaries ofrepparttar 116262 wood. When a tree is growing water and food are transferred up throughrepparttar 116263 cells and are carried throughoutrepparttar 116264 tree.

Once a tree is fellrepparttar 116265 free water inrepparttar 116266 wood is lost rather quickly butrepparttar 116267 bound water trapped inrepparttar 116268 straw like cell is slower to dissipate. Asrepparttar 116269 level of bound water is reduced these straw like cells get narrower in diameter but maintain their length. This isrepparttar 116270 fundamental reason that wood expands and contracts across its width but has almost no expansion length wise.

When working with wood it is very important to allowrepparttar 116271 wood to expand and contract with changes in humidity. As humidity risesrepparttar 116272 straw like cells expand in diameter withrepparttar 116273 opposite effect occurring asrepparttar 116274 relative humidity falls.

Ways to accommodate expansion

Lets use a cutting board forrepparttar 116275 first example. A solid wood cutting board with a bread board edge secured with a tongue and groove joint. One edge hasrepparttar 116276 bread board edge secured on both ends with a dowel throughrepparttar 116277 tongue The other bread board edge is secured withrepparttar 116278 same tongue and groove joint but this end only has a dowel inrepparttar 116279 center ofrepparttar 116280 piece.
