basically wood bending

Would putting more rubber bands around the stack, or heavy weight on top of the stack also decrease the chance of warping? Also, is thicker or thinner wood more likely to warp? Thanks.jander14indoor wrote:Don't believe in stupid questions, just something you haven't learned yet. So:
Warping. Wood shrinks as it dries and shrinks different amounts depending on which direction through the trunk you go. It shrinks much more along a circumference, than along a radius. As a result, a flat/straight cut piece of wood can twist and distort as it either dries from cutting, or as it absorbs/desorbs moisture from the air as humidity changes (dry, heated air in winter, humid hot air in summer if no AC). Which way it distorts depends on where you cut the wood from the trunk, which way the tree was leaning, which way the sun was, even which way the wind blew most of the time. This twisting/distorting is called warping.
So, why lay it flat? IF the warping forces are small enough, and if you lay the wood on a flat surface in a nice stack, gravity restrains the twisting forces so the wood stays flat and the forces become internalized. It may still warp when you unstack or cut the wood, but less likely. Standing on end, there's nothing to restrain this twisting and the wood can take amazing shapes.
