to head off these problems by using solid
construction techniques and stable mate-
rial to build square cases and doors.
Mind the gap—Every door needs as uni-
form a gap as possible around all four edges
so that the door doesn’t stick as it grows or
shrinks during seasonal changes in humid-
ity. A narrower gap looks better. Knowing
how much of a gap to leave is a matter of
Use marking gauges and
a marking knife to make
fine layout lines. Take all of
your settings directly from
the hinge for accuracy.
Again, use the hinge
itself to set the length
of the mortise. Hold-
ing the hinge in place,
cut tick marks into the
corner of the door stile.
Then carry those lines
across the mortise with
a square.

Set a second
marking gauge
for the depth of
the mortise. If
the hinge leaves
are tapered, set
the gauge at their
thickest point.
Set the first marking
gauge for the width of
the hinge. Set it about
(^1) ⁄ 32 in. short of the center-
line of the hinge knuckle.
The light pencil lines at the
end of the mortise indicate
where to stop the marking-
gauge cut.

experience and skill. I’m guided by a wide
board hanging in my shop whose width I
measure from time to time and mark on the
board. In early May I leave a slightly wider
gap to allow for the higher humidity in the
coming months. Somewhere between^1 ⁄ 16 in.
and^1 ⁄ 32 in. is about right.
Hinges vary in one way that usually isn’t
indicated in catalogs. If the two leaves do
