[edit]Believe it or not, there are instances where natural "warping" of wood may be both useful and desirable, IF one knows what is most likely to happen... Please explain what is most likely to happen in the following Case: Consider a nominal 2" by 12" Wood Plank where the "Rings" of the Tree from which the Plank was cut are clearly visible in the end grain. Is this plank most likely to "Cup" in the SAME direction as the Curvature of the Tree Rings, or in the Opposite Direction?68.40.200.174 (talk) 00:19, 20 April 2008 (UTC)

whoa intro to subject??
[edit]..I don't care at all how much wood warping costs the wood industry, if I DONT KNOW WHAT IT IS.... 75.72.221.172 (talk) 03:04, 16 February 2009 (UTC)
it typically cups in the opposite direction of the grain —Preceding unsigned comment added by 68.143.184.162 (talk) 20:35, 16 September 2009 (UTC)
Problem is in the title?
[edit]Trying to explain why wood warps is irrelevant and not needed. You might as well ask why and how wood grows?
It would be better to have the title "Wood Defects" and then list these, the characteristics and reasons.
The article could then be expanded to include all defects including, 'warps', knots, sloping grain, blue sap, case hardening etc, etc.
To understand why such defects occurs needs an understanding of tree growth, conversation of the lumber (timber), and seasoning. 'Warping' as such is a generic term for some of the defects caused by some irregularity or problem during the growth, conversion and seasoning plus eventual storage.

Little Understood?
[edit]I believe that the body paragraphs, especially the line "This little understood process is finally being looked at in a serious way." are misleading and inaccurate. Wood obviously warps because the wood shrinks unevenly while drying, and warp is predictable depending on the orientation of the rings and knots and the way the lumber is sawn from the logs. These two paragraphs, composing most of the article, seem more like an advertisement for Dr. Zhiyong Cai's research, than encylopedic information.
I would prefer to see more information about the well known causes of warping, methods used to reduce or prevent warping, methods to correct or accommodate warping once it occurs, and historical information (such as antique carpentry "winding sticks", hand and jointing planes, and similar).97.121.20.16 (talk) 08:14, 11 September 2014 (UTC)
