What is wood? Why wood warps? Cutting & Storage Methods

Post by Suso » Mon Jul 27, 2020 10:06 am

I wrote an article on the site's blog to clearly explain, once and for all, this matter.
Here you'll find the full article:

After reading the article, you may come back to this post to add information or ask questions.

In order to better understand wood sawing and drying methods, we must first understand what wood is and how it behaves on a structural level. Wood is an excellent raw material with good mechanical properties, as well as being easy to machine or process. It is made up of cellulose, hemicellulose, and lignin fibers.



A- The tree’s life starts in a forest somewhere in the planet.
B- The annual rings are far apart, the tree is growing in a favorable climate.
C- Elliptical rings, for 10 years the tree has been growing on a slope or swept by constant strong wind.
D- Narrow or compact rings, due to a few years of dry weather or because a bigger tree is stealing sunlight and nutrients from it.
E- The rings are, once again, far apart. The weather has improved or the tree that was stealing its nutrients has been cut down.
F- A sign of a small fire when the tree was 28 years old.
G- Once again, compact rings. Judging by the size of the tree at that point, it must have been caused by a few years of drought, rather than a tree stealing its nutrients.
H- Continuous slow growth. Either due to persistent drought or an insect infestation.

Wood that is warped is curved or bent in certain areas from the moisture content being different in specific areas of the wood. This causes some areas to dry faster than others and shrink in size, causing the wood to bend or curve.
