Searchlight
The searchlight is located in a separate frame on the etched parts
sheet. Always bend the sheet material towards the etched-in
groove to avoid the parts breaking.
First bend the two sides of the box 215 upwards through 90°.
Insert the two side panels 216 in the notches in the bottom.
Wrap masking tape round the box thus produced. Place this
assembly in a vice or between two pieces of wood in such a way
that the seam to be soldered is horizontal, and does not make
contact with anything.
Tack the parts together on the inside.
The box does not need to be watertight.
Repeat this procedure with all four corners and the bottom.

Pass the swivel tube 218 through the cover 217 and the
hole in the floor of the box. Align the cover, and tack it to
the side walls with spots of solder.
Tape the brackets 219 and 221 to a strip of balsa or similar,
with the bending grooves facing up.
Continue the holes in the brackets about 2 mm deep into
the wood using a 1.0 mm drill.
Fit the pivot pins through the brackets and into the wood,
and cut them off about 0.5 - 1 mm above it.
Solder the wires in place and clean up the soldered joints.
Now drill the 2 mm and 3 mm holes through the brackets
and into the wood. Insert the tubes 218 and 220 through
the wood, and fit the brackets on the tubes with about 1
mm projecting. Solder the joints using a minimum of solder.

Glue horizontal reinforcements 224 to the lamp housing, and drill holes
through the housing. Drill holes in the other side of the housing, taking care
that the holes are at right-angles and exactly opposite each other. Carefully
position the opposite reinforcement 224 using the drill as a guide.
Drill a hole for the cable in the bottom of the lamp housing.
Slip the two bracket tubes into each other. Cautiously bend the brackets to
shape, and fit the pivot pins in the reinforcements. Press the brackets firmly
against the lamp housing using two fingers, and swivel slightly to left and
right on the tube; this will cause the bends to align themselves. You may
need to apply more solder to the bending grooves.

Glue the backplate 225 to the housing 223.
Glue the handles 226 in the holes. Glue the latches 227 in the holes
above the housing. The searchlight can now be painted.
Cut the LED pins to length and solder the wires to them.
Insulate the soldered joints and pins with heat-shrink sleeves or similar.
Thread the wires through the hole in the housing, and fit the LED in the
reflector. Place the reflector in the lamp housing, followed by the lens.
Secure the lens with contact cement or canopy glue. Don't use cyano, as
sooner or later this will 'bloom' (turn milky).
The two 0.8 mm holes in the top and bottom of the backplate can be
used to push out the reflector with a pin, drill or similar, in case a repair
is necessary.
Chain stoppers
Two chain stoppers have to be built.
Glue together parts 231 - 233 to form the base. Note that part 232 must
be bevelled at the top.
Glue the shaft 239 in the centre of the retaining plate 238. Glue the two
side parts vertically to the slider plate 234. Fit the shaft and the retaining
plate 238 before the glue sets.
Cut the crankshaft to length and solder it to the angled crank.
Form a loop in the linchpin 242 as shown.
Insert both parts; the cranks face amidships.
Paint the chain stoppers.
These assemblies are glued in place together with the anchor winch and
chain.

Anchor winch
The winch base consists of the double-T supports 243 and the base
plate 244.
Glue the double-T supports 243 to the base plate as shown in the
drawing alongside.
The centre of the supports is indicated by a dotted line. Align the
supports with the slots in the baseplate. They must not project into the
slots.

Glue the two bearing brackets 245 together.
Glue this assembly in the slot in the base plate. Glue the bearing bracket
246 in the right-hand slot in the base plate.
Thread the shaft through the pivot holes. Glue the reinforcement 248 to
the base plate, flush at the bottom, and flush with the outside of part
246. Note that parts 245 and 246 must be set at right-angles to the
base plate.
Fit the plates 249 and 250 on the shaft, and glue them to the support
246 - not to the shaft. Glue the plates 251 and the distributor 252 in
place. Bend the guides 255 to the shape shown and glue them in place.
Glue the small cover 254 in place.
