nks to form the deck. In fact,
this job is quite beyond the ability, to say nothing of the patience, of
the average young model-builder. A very simple method of producing
imitation planking is shown in Fig. 99. A sharp knife and a
straight-edge are the only tools for this work. The straight-edge is
merely used to guide the knife. The cuts should not be made too deep,
and they should be made a uniform distance apart. When the deck is
finished in this manner and varnished over, a very pleasing effect is
produced. In fact, if the work is done carefully, the deck looks very
much as if it were planked.

A small life-boat is shown in Fig. 100. This can easily be carved to
shape from a small piece of soft white pine. The center is gouged out,
and tiny little seats made of thin strips of wood are glued in place.
Two small screw-eyes are placed in the boat, for fastening it to the
davits. The davits are shown in Fig. 101, at _A_ and _B_. They are made
by bending a piece of small brass rod, as shown. One end of the rod is
hammered flat, and a hole is made in it with a very small drill. Holes
a little under size are drilled in the deck, and the davits are forced
into these. The method of suspending the life-boat from the davits is
shown at _B_, Fig. 101. The little blocks of wood are glued on to a
thread to represent pulleys, and they are, of course, only imitation or
dummy pulleys.

The method of producing port-holes is shown in Fig. 102. A hole is first
bored through the wood with a bit of the proper size. The size of the
port-holes depends entirely upon the size of the boat. A piece of brass
tubing is then cut off with a hacksaw to form a brass bushing. The
outside diameter of this tubing should be the same as the size of the
bit used. For instance, if a 1/2-inch bit is used, brass tubing 1/2 inch
in diameter should be purchased. Such tubing can be obtained from any
hardware store. Celluloid, such as that used for windows in automobile
curtains, is glued to the inside of the port-holes. This makes a
splendid substitute for glass. It
