As part of the permanent collection
of the Department of the Navy, it is reasonable to expect
a new ship model to last one hundred years before deterioration
is visible. Therefore, resistance of models and parts to
the actions of temperature, humidity, and light is essential.
Extreme care must be given to select materials which are
known to be compatible and will not, in time, interact chemically.
Although only a few materials
are prohibited in "Specifications for Construction of Exhibition
Models of U.S Naval Vessels," some recently developed model-building
materials and techniques should be avoided until sufficient
time has passed to properly evaluate their longevity. Though
some of these recently introduced materials may ultimately
test superior to more traditional techniques, substances
of unproven longevity should not be employed in models built
under these specifications. It is advised that fiberglass
resins, styrene, expanding foams, casting resins, and cyanoacrylate
glues be avoided when other materials can possibly be used.
Workmanship |
|
Workmanship shall be
in accordance, in every respect, with the best model-building
practices. Hulls shall be smooth, fair, and symmetrical;
without blemishes, sap pockets, or tool marks, and
shall be scraped and sand-papered to smooth surface.
Machined parts shall bear no tool marks. Castings
shall bear no visible mold marks. In no case shall
glue alone be deemed sufficient to hold deck houses,
fittings, or other appurtenances in place. Mechanical
fastenings such as screws and pins shall be used in
addition to adhesives.

Range |
|
Models shall be museum
quality and shall consist of the whole exterior of the
vessel from keel and appendages to the top of the highest
antenna or fitting, and shall include interiors of such
enclosures, conning stations, deck house topside stations,
gun and missile stations, hangars and bays as are accessible
to weather without opening watertight doors or ports.
Generally, all items on the prototype twelve inches
or larger for 1:96 scale (six inches or larger for 1:48
scale) will be reproduced.
Rigging.
Running and standing rigging and cable antennas shall
be represented. Windlasses shall be wound with appropriate
cable or line.
Ports
and Windows.
Large windows shall be indicated on the model by clear
acrylic plastic. Ports shall be transparent, and shall
have a hole bored behind them to give an appearance
of depth.
Gun Turrets.
Gun turrets shall have the openings in face plates required
for elevation of the guns. Where required, gun shrouds
shall be represented.
Aircraft
and Vehicles.
Where appropriate for the mission of the actual vessel,
and visible on the model, scale aircraft or vehicles
will be provided. Landing pads shall be provided with
at least one representative scale aircraft.
Small
Boats. Small
boats shall be mounted on davits or otherwise as actually
carried and shall show all details, motors, and equipment
twelve inches or larger in actual size. If represented
with weather covers, gripes and all fastenings visible
are to be shown. Landing craft and whale boats shall
be without covers and shall show all exposed details
and equipment.
Special
Features. Special
functional features peculiar to the vessel (for example:
stern doors, towing devices, special antennas, fire
fighting gear, etc.) shall be shown. |
