The Doors (Fig. 22).--These are the most difficult parts to construct, as
the braces which prevent the front edges dropping must be carefully fitted
in order to do their work properly.

The eleven outside boards of each door are held together by two 4-inch
ledges 6 inches away from the ends, and one 5-inch central ledge. Allow a
little "spare" on the boards for truing up. Boards and ledges having been
nailed together, lay a piece of 4 by 1-1/2 inch batten across the ledges on
the line which the braces will take, and mark the ledges accordingly. Next
mark on the batten the ends of the braces. These project half an inch into
the ledges, and terminate on the thrust side in a nose an inch long, square
to the edge of the brace. The obtuse angle is flush with the edge of the
ledge. Cut out the braces, lay them in position on the ledges, and scratch
round the ends. Chisel out the notches very carefully, working just inside
the lines to ensure the brace making a tight fit. If there is any slackness
at either end, the brace obviously cannot carry the weight of the door
until the door has settled slightly, which is just what should be
prevented. Therefore it is worth while taking extra trouble over this part
of the work.

Cautions.--Don't get the nose of the brace too near the end of the ledge.
Nail the boards on specially securely to the ledges near the ends of the
braces.

Fitting the Doors.--The doors should now be laid on the top of the frame
and secured to it by the four hinges. The long ends of these are held by
