Just in case you don't know...
Wood sometimes continues to stabilize (equalizing stress and moisture) after final sawing to length. The degree to which it does so depends on how thick was before it is cut to final shape, how the slab was sawed (what angle in relation to the growth rings), how dry it is (moisture content), and how dry the room is where it will be stored. Sometimes it doesn't move much, but other times it can bow or twist a bit, or crack, esp if the moisture content in the wood and the moisture content in the storage area are really different. Cracking can be a big problem, since it can ruin an otherwise great slab.
For that reason, a lot of guys like to dunk the last 3" or 4" of the ends of the newly sawed slabs (or stock blanks) into some hot (melted) wax as soon as the pieces are cut to length. That will slow down the release of moisture from the end grain, so as to help keep the end grain from cracking. (I've also used vaseline for this, but I wouldn't recommend it unless you knew you had plenty of margin. You'd hate to end up with an oily stain that wouldn't take colored stains.)
