can be obtained at garages and
automobile supply stores for a few cents a square foot. The model boat
builder can also use either mica or glass for this purpose, although
thick glass looks somewhat out of place.

A binnacle is shown in Fig. 103. This is made from a solid piece of wood
cut with a semi-spherical top. The steering-wheel is made of a wheel
from an old alarm clock. The teeth of the wheel should be filed off.
Tiny pieces of wire are then soldered in place on the wheel, as shown. A
pin driven through the center of the steering-wheel is used to fasten it
to the binnacle. The binnacle itself can be held to the deck either by
glue or by a small screw.

A torpedo-tube for use on model destroyers and battleships is shown in
Fig. 104. First two disks of wood are cut. Then a circular piece is
cut, as shown. Two brass nails are then driven through this piece into
one of the disks. An upholstering tack is driven into the end of the
circular piece, as pictured. The method of attaching the torpedo-tube to
the deck is clearly illustrated in Fig. 104 and no further directions
need be given. If the model-builder has a small piece of brass tube on
hand suitable for use in this case, it will make a much better appearing
tube than the piece of wood illustrated.

A wireless antenna is shown at Fig. 105. This is a fitting that will do
much toward improving the appearance of any craft. Very fine copper wire
is used for the aerial. The little spreaders are cut to shape from wood,
and a tiny hole is punched through them through which the wire is
placed. Black beads slipped on the wire serve very well as insulators.
The lead-in wire which drops to the wireless cabin is attached to the
aerial by winding it around each one of the aerial waves. The aerial
should be suspended between the masts of the vessel. A few words should
be said about masts in general. If there is one way in which a
model-builder can destroy the appearance of a model boat, it is by using
badly proportioned masts. The average boy seems inclined to use a mast
of too great a diameter, which makes it out of proportion with the rest
of the boat. It is better to have a mast too small rather than too
large.

The method of producing railing is shown in Fig. 106. The same small
brass rod that was used for the davits can be used for the rail
stanchions. One end of the stanchions is hammered flat and drilled out.
The stanchions are fastened to
