Be very careful with glue.

Panels are normally NOT glued.  They are set in grooves so that
movement is possible, and the direction of grain of the rails is
carefully chosen.

As humidity changes, the panels expand and contract and move in the
grooves.  But they only expand along the grain direction.

If you put glue in the wrong groove (depending on the grain direction)
then the panel WILL split.

I thought wood expands 'cross grain' as the cells fatten with
moisture, not "...along the grain..." thus lengthening a piece of
wood.

Which is it?
