"Measure
twice, cut once,” said the old craftsman.
Only careful planning and
patient
skill make a dovetail.
Early
cabinetmakers were faced with the problem of joining two pieces
of wood together at a right angle so that they would bear the stress
not only of use but of the weather as well. Especially in places where
the summers are hot and humid and the winters are dry and cold, a plank
of wood might change its dimensions by a quarter- to a half-inch. Quite
enough to make joints fall apart and drawers stick.
The dovetail joint holds because
the two interlocked pieces of wood
expand and contract at the same rate. The direction of the pull is
against the locking of the joint. The byproduct of all this fine craft
is a joint so precisely fitted that it is a thing of beauty in and of
itself.
Cutting a dovetail joint is a
demanding skill. The lines must be laid
out with great care, and the cutting must be carefully done using a
thin saw. The waste must be slowly trimmed away with a sharp chisel
until both sides mate tightly. The making of a dovetail joint requires
planning, skill, and patience.
Nowadays, cheap synthetic materials
do not breathe with the seasons.
That might reduce inconvenience, but it has also reduced the change for
another relationship to Tao. For when the cabinetmakers sought to build
furniture that was compatible with the wood, the seasons, and their own
ingenuity, they were perfectly in tune with Tao.
