Recess
Divide the two exhaust pipes 132 and 133 centrally at an
angle of 45°, and glue them in the rear face of the exhaust
pillars.
The two servos required for rotating the fire monitors can now
be screwed to the underside of the servo mounts 119.

Fire monitors
Please take care to follow the sequence of the illustrations when
assembling the monitors.
Clean all the parts with warm soapy water and a brush to remove
any excess material, as it could come loose later and block the
monitors when they are operating.
Cut a slot about 3 - 4 mm deep on one side of the 3.0 mm brass
tube (2) at the top. Fit the tube in the bottom section (1); it should
project at the top by about 1 mm.
Glue together the top and bottom sections (1 + 3); thick cyano is
the best adhesive to use for these joints.
Thread the column (4) onto the 3 mm tube and glue the parts
together.
Push the 4.0 mm tube (5) into the bottom of the column (4) as far
as it will go, and glue the joint. Glue the spindle bridge (7) to the
top section (3), and glue the handwheel (8) to the spigot.
Fit the base (6) as shown, taking care not to glue it to the monitor
column or the tube, as it acts as the pivot bearing.
Glue together the jet nozzle and the spray nozzle.
The diameter of the front holes in the spray nozzle is 0.6 mm. You
may need to drill them out.
Glue the nozzle you wish to use in the main monitor body.
When painting the monitors take care to prevent paint blocking
the holes.

Installing the glazing panels
Don't remove the tabs in the sides of the glazing panels, as they help to align the
panels. Remove the protective film from one face of the glazing panel, leaving the
other in place.
Apply a small amount of adhesive to the back of the window frame (etched part).
Place the panel in position centrally, leaving a recess all round; apply a little glue
in the recess and insert the glazing panel in the painted wall.
From the inside the gap can safely be filled with a little adhesive, as the film
protects the panel from smearing. The inner film can be peeled off when the glue
is dry.
Note regarding adhesive: don't use cyano, as this always produces a milky 'bloom'
some time after drying.
Instead use clear contact cement, e.g. Canopy Glue (water-based), UHU Hart
Plastic or UHU extra.
The windows in the side walls 66 do not have etched frames; only the forward
windows in part 67 have frames.

A good method of swivelling the monitors is to fit pulleys on the brass tube and drive them from a servo using rubber bands. In this case the hole
in the servo mount should be fitted with a plain bush or ballrace. The fire monitor drive components are not included in the kit.
The pump can be installed aft of the battery support 22 on the bottom of the hull. The intake nipple (tube Ø to suit your pump) should be glued aft
of the pump on the centreline of the hull, projecting by 1 mm on the outside. Glue it in place on both sides of the hull.
Superstructure deck
Lay scrap pieces of 1.5 mm ABS sheet under the superstructure deck 138 to act as spacers.
Glue the base rails 139 to the edges of the deck; four separate parts are required on each side. The mitred joints must be trimmed individually. Add
the forward base rail, followed by the rear rail. The latter must not project at the sides, since it has to fit between the exhaust pillars.

Steel strip
Magnet
One option for making the deck detachable is to secure it with magnets; these are not included in the kit. The retaining magnets do not need to
be excessively strong.
Glue the magnet supports 140 in the corners of the superstructure to suit the thickness of the magnets you wish to use. When fitting the magnets
check that they do not block the openings for the railing stanchions. Glue the magnets in place. A piece of tinplate from a tin can is all you need
on the opposite face.
Lay the strip of metal on the magnet and apply adhesive to the exposed surface. Lay the deck on top and allow the glue to set hard.
The superstructure deck can now be painted.
