screws driven through the boards into the bearers; the cross pieces are
screwed to the uprights of the door frame. The doors when closed should
make a good but not tight fit with one another.


PUTTING THE PARTS TOGETHER.

The two sides, front, and back are now assembled, on a level surface, for
drilling the holes for the bolts which hold them together. The positions of
the bolts will be gathered from the drawings. Get the parts quite square
before drilling, and run the holes through as parallel to the sides as
possible. If the bolts are a bit too long, pack washers between nut and
wood until the nut exerts proper pressure.

Caution.--The hole must not be large enough to allow the square part just
under the head to revolve, for in such a case it would be impossible to
screw up the nut. Its size ought to be such as to require the head to be
driven up against the wood.

The Roof.--The boards of this are attached to a frame which fits closely
inside the tops of the sides, back, and front. To get the fit of the frame
correct, it must be made a bit too wide in the first instance, and then be
bevelled off at the front, as shown in Fig. 23, and the reverse way at the
back. The ends are notched for the stays AA, and the frame then tacked
firmly, by driving nails into the sides, etc., below it, in the position
which it will occupy when the roof is on, except that it projects upwards a
little. Cut off twenty-five boards 3 feet 7 inches long. Omitting the end
ones for the present, lay the remainder up to one another in order, their
