[Woodworkers] A question?

[jaspertops at bluemarble.net]

Sometimes it won't make a difference.  I actually had a board that was
kiln dried and was perfectly straight and flat.  As I was ripping it
roughly down the middle, I was able to watch each piece begin to twist and
warp toward each other on the other side of the blade.  There was still
internal tension in that otherwise perfectly straight and flat board.
