Actually the process begins with timber selection. It is considered to
be good practice to select out the most stable stock (ie: as near to
quartersawn as possible) for the door frames and such. It is usually
considered to be best to do the stock prep and joinery for these items
on the same day, as the reference planes can become out of spec quickly
and the joinery needs to be cut before any relaxation can occur. A
secondary consideration would be the selection and preparation of any
exposed members such as casing and pilasters. If your carcase is to be
of solid stock it would be best to joint and glue the panels on the
same day, for the above reason. The stickering of stock should occur
during the stage that the timber is in a rough state. You will do
yourself a great favor if you bring the timber to final dimensions and
create the joinery on the same day, whenever possible. If you do not
do this, you run the risk of your reference edges becoming out of
square to each other and your joinery will be the worse for it. The
concern for Equilibrium Moisture Content is most perfectly put at the
rough timber stage. If you remove more or less equivalent mass from
the opposing faces during prep, you will not have to worry about
distortion from unequal moisture content throughout the section.
