t, try-square, and all other appliances likely to be required.

Whenever it is possible to break up the process into steps, each step
can be taken with more deliberation. For example, in assembling framed
pieces that are doweled, it is well to glue the dowels into one set
of holes beforehand, making tenons of them, as it were. Time is
thus saved for the final assembling when haste is imperative. The
superfluous glue around the dowels should be carefully wiped off.

Likewise in gluing up framed pieces, sections may be put together
separately: as, the ends of a table, and when they are dry then the
whole may be assembled. When the pieces are together the joints should
be tested to see that they are true, and that there are no twists.

A good way to insure squareness, is to insert a diagonal brace on the
inside, corner to corner, as in Fig. 294, p. 195. Such a brace should
be provided when the trial assembly is made. Another good way to
insure squareness is to pass a rope around two diagonally opposite
posts, and then by twisting the rope, to draw these corners toward
each other until the frame is square.

The superfluous glue may be wiped off at once with a warm damp cloth,
but not with enough water to wet the wood. Or by waiting a few minutes
until the glue thickens, much of it can readily be peeled off with an
edge tool. Either of these ways makes the cleaning easier than to let
the superfluous glue harden.

The work when glued should remain at least six hours in the clamps to
harden.

HINGES

Hinges, Fig. 233, are made in several forms. The most common are the
butt-hinge or butt, the two leaves of which are rectangular, as in
a door-hinge; the strap-hinge, the leaves of which are long and
strap-shaped; the Tee-hinge, one leaf of which is a butt, and the
other strap-shaped; the chest-hinge, one leaf of which is bent at a
right angle, used for chest covers; the table-hinge used for folding
table tops with a rule joint; the piano-hinge, as long as the joint;
the blank hinge or screen-hinge which opens both ways; the stop-hinge,
which opens only 90 deg.; and the "hook-and-eye" or "gate" hinge.

The knuckle of the hinge is the cylindrical part that connects the two
leaves, Fig. 234. The
